Goods and Services Tax in Singapore for Businesses

Goods and Services Tax in Singapore for Businesses

Goods and services tax in Singapore is charged at 9% on standard-rated supplies. A business must first establish whether it needs GST registration, then determine how each sale and purchase should be treated. Registration, invoicing, input tax claims, returns and payment are separate responsibilities, with additional rules for imports and cross-border transactions.

This guide follows those decisions from the first turnover assessment through to the next return. It also explains voluntary registration, InvoiceNow, self-review tools, relief schemes and household support. Rules and official sources were checked on 26 October 2026. The examples are hypothetical teaching illustrations, not client cases.

Start by reviewing turnover and transaction types. Once the registration position is established, check invoices and purchase evidence before reconciling the return. Keep the payment confirmation separately from the filing acknowledgement.

What GST is and why Singapore uses it

GST is a broad-based consumption tax, similar to value-added tax in other countries. Registered businesses collect output tax on taxable sales and can recover qualifying input tax on purchases. The final consumer generally bears the tax because they cannot make a business input tax claim. The Goods and Services Tax Act 1993 provides the legal framework; IRAS administers the tax, while Singapore Customs handles import collection and related border procedures.

GST began on 1 April 1994. Its rate history is useful context, but current invoices must use the rate applicable to the transaction, including any relevant transitional rules.

Effective dateStandard GST rate
1 April 19943%
1 January 20034%
1 January 20045%
1 July 20077%
1 January 20238%
1 January 20249%

IRAS publishes the current rate and historical changes. An older example using 7% or 8% should not be copied into a current standard-rated transaction without checking its date and circumstances.

GST is distinct from corporate income tax on taxable profits, customs or excise duties on specified goods, property tax and stamp duties. A company can face several of these obligations in the same transaction or accounting year. Keep their calculations and deadlines separate.

The Ministry of Finance explains GST as part of funding public expenditure, including healthcare and support for an ageing population. Its policy approach combines broad consumption taxation with targeted transfers and subsidies. For business owners, the practical implications include customer prices, recoverable purchase tax and ongoing compliance costs. See MOF’s GST policy explanation.

How output tax and input tax work

Output tax is GST a registered business accounts for on its taxable supplies. Input tax is GST incurred on purchases or imports. Only input tax that satisfies the claim conditions can be deducted.

Net GST payable equals output tax minus allowable input tax, after relevant adjustments. If the allowable input tax is greater, the return may show a refund position. A refund remains subject to the applicable rules and any verification by IRAS.

A supply chain example

Assume all three businesses below are GST-registered, every sale is standard-rated and the shown purchases qualify for full input tax recovery. The first trader’s earlier purchases are outside this illustration, so no input credit is shown for that stage.

StageSale excluding GSTGST chargedNet GST paid to IRAS
Trader sells goods to distributorS$2,000S$180S$180
Distributor resells to retailerS$3,000S$270S$90 after deducting S$180
Retailer resells to consumerS$5,000S$450S$180 after deducting S$270

The consumer pays S$5,450. The three illustrated net payments total S$450, equal to the GST on the final sale. Each business deducts eligible purchase tax rather than paying all the GST it collects as an additional business cost. IRAS explains the supply chain mechanism.

Keep the GST balance visible in cash-flow forecasts. Tax collected from customers is not an unrestricted addition to trading margin, even when it enters the same bank account as sales proceeds.

Which supplies attract GST

Classify the transaction before selecting a tax code. A zero amount charged to the customer does not establish whether the supply is zero-rated, exempt or outside scope.

CategorySales treatmentTypical situationWhat to check
Standard-rated9% GSTMost local sales of goods and servicesRegistration, valuation and time of supply
Zero-rated0% GST on a taxable supplyQualifying exports and international servicesStatutory conditions and supporting evidence
ExemptGST is not chargedCertain financial services, residential property transactions, digital payment token supplies and investment precious metalsPrecise exemption and related input tax attribution
Out-of-scopeOutside Singapore GST scopeGoods sold from one overseas location to another without entering SingaporeGoods movement and the actual contractual arrangement

Zero-rated supplies remain taxable supplies and generally enter the ordinary taxable turnover calculation, subject to its specific exclusions. Exempt supplies have different input tax consequences. Partial exemption rules and concessions need separate consideration where relevant. IRAS provides guidance on exempt supplies and their distinction from zero-rating.

A foreign customer, foreign currency or overseas bank payment does not by itself establish zero-rating. For services, check the relevant international service provision and beneficiaries. For goods, retain the export evidence required for the treatment. International services and exports of goods have dedicated official guidance.

Gifts, samples, deposits, vouchers, reimbursements and private use of business assets can need a different analysis from an ordinary sale. Use the IRAS transaction scenarios before applying a familiar tax code to an unfamiliar arrangement.

When GST registration is compulsory

Singapore incorporation and GST registration are different matters. The ordinary compulsory threshold is taxable turnover exceeding S$1 million. Apply the correct test rather than treating every moving 12-month total as an immediate retrospective trigger.

TestWhat creates the obligationApplication deadlineOrdinary effective date
RetrospectiveTaxable turnover exceeds S$1 million for the January to December calendar yearBetween 1 and 30 January of the following year1 March of that following year
ProspectiveReasonable expectation that taxable turnover will exceed S$1 million in the next 12 monthsWithin 30 days after the forecast dateTwo months from that date for liabilities arising on or after 1 July 2025

For example, a business signs a supported contract on 10 August 2026 that creates the relevant expectation for the next 12 months. Its application is due within 30 days of 10 August, while the ordinary effective registration date is 10 October 2026. The two-month implementation period does not extend the application deadline.

Taxable turnover is a defined amount, not profit, total bank credits or every receipt in the accounts. It includes relevant standard-rated and zero-rated supplies, but excludes exempt supplies, out-of-scope supplies and disposals of capital assets. Certain otherwise exempt financial services that qualify for zero-rating also have a specific exclusion from this turnover calculation. Refer to IRAS registration tests and turnover definitions.

Keep signed contracts, accepted quotations, confirmed orders and other reliable forecast evidence. An ambitious sales target alone is insufficient. Record the date the evidence changed the assessment and review turnover again when significant contracts or business changes arise.

Exceptions require their own conditions. A business making wholly or mainly zero-rated supplies may apply for exemption from registration. A retrospective liability may also have an exception where the prospective position and supporting circumstances satisfy IRAS requirements. Do not assume that expected turnover decline automatically removes registration obligations. Reverse charge and overseas vendor registration can create separate liabilities.

Deciding whether to register voluntarily

A smaller business may be eligible to register voluntarily. Evaluate recoverable purchase tax against customer pricing, administration and continuing obligations. Voluntary registrants generally remain registered for at least two years and must meet the applicable conditions, including GIRO and InvoiceNow where required.

For a business selling mainly to GST-registered customers, those customers may be able to recover the GST charged if their claims qualify. A consumer-facing business needs to consider its final selling price. Absorbing GST within an unchanged price reduces the amount retained before other costs.

Use actual invoices and contracts to compare the alternatives. Include accounting software, invoice-data transmission, record maintenance and return preparation. Registration itself does not prove that sales, profits or customer confidence will increase. The official voluntary registration factors explain both costs and benefits.

Group structures and overseas entities

Related entities, independent divisions and joint ventures may need a structure-specific review. Group and divisional arrangements have eligibility and approval conditions; they do not arise automatically because a business uses multiple entities or cost centres. Consult the special registration guidance.

An overseas entity importing goods for supply in Singapore should also consider who imports and sells in whose name. Registration in the overseas entity’s own name can require a local Section 33(1) agent. A qualifying Section 33(2) arrangement instead places particular responsibilities on the Singapore agent. These are conditional alternatives, not interchangeable labels for a logistics provider; review the overseas entity registration options.

How to apply for GST registration

First establish the correct registration path and effective date. Then prepare the application using the current IRAS instructions rather than an old paper form or a generic incorporation checklist.

Step 1 Confirm the basis and supporting evidence

Prepare the turnover calculation, relevant contracts, business details and documents applicable to the entity type. If someone applies on behalf of the business, confirm the authorisation required for that digital service.

Step 2 Complete applicable learning requirements

Voluntary applicants should check who must complete the GST learning course and assessment, and whether an exception applies. Confirm the responsible persons and any applicable exemption before submitting the application.

Step 3 Submit through the appropriate digital service

Arrange the necessary Corppass authorisation and submit the application and supporting documents through the applicable myTax Portal service. Overseas vendors using the simplified regime have a separate route. Set up the required payment arrangement for voluntary registration.

Step 4 Track tax approval and banking arrangements separately

IRAS may request further information. Respond using the application reference and keep a copy of the submission. Bank approval of a GIRO instruction is separate from approval of GST registration. Plan around current processing guidance and allow time for information requests.

Step 5 Confirm the number and effective date

The IRAS approval letter states the GST registration number and effective date. Configure invoices, tax codes, pricing and purchase records around that date. Do not start collecting GST merely because an application has been submitted. The official application guide explains the steps and entity-specific requirements.

When to charge GST and report a supply

GST-registered businesses generally charge 9% on standard-rated local supplies. Check exceptions and special accounting arrangements before issuing the invoice. For example, prescribed goods sold to a registered business customer may fall under customer accounting when its conditions are met. The customer accounts for output tax on the supplier’s behalf; this is not a zero-rated or exempt sale. See customer accounting for prescribed goods.

The timing question is separate. For most transactions, the time of supply is the earlier of invoice issuance or payment receipt. This determines the return period in which the supply and output tax are reported.

For example, assume an ordinary standard-rated supply is invoiced on 28 September and paid on 12 October. It belongs to the accounting period covering September. If payment instead arrives on 20 September before an October invoice, the earlier receipt generally determines the timing. These examples assume the ordinary rule and no relevant special scheme or exception.

Contracts, pro-forma invoices and sales orders should not automatically be treated as invoices triggering the rule. Deposits held as security, continuous services, sale-or-return goods and reverse charge have further details. Use IRAS time of supply guidance to resolve those situations. A customer’s late payment does not generally postpone output tax already triggered by an invoice.

Calculating GST and issuing invoices

For a price excluding GST, GST equals the price multiplied by 9%. A S$2,000 sale produces S$180 GST and a S$2,180 total. For a GST-inclusive price, extract the GST using 9 divided by 109. The tax within S$2,180 is therefore S$180.

When a business absorbs GST within an unchanged S$1,000 consumer price, the GST component is S$82.57 after rounding to cents, leaving S$917.43 before other costs. Absorption changes who bears the price impact, not the obligation to account for tax.

Registered businesses generally display GST-inclusive prices to the public, subject to the specific exceptions. Review website prices, menus, quotations and advertisements together. IRAS price-display rules should guide the final presentation.

Tax invoice essentials

A tax invoice is generally required for a standard-rated supply to a GST-registered customer within 30 days from the time of supply. It needs the required supplier and customer details, GST registration number, invoice identification and date, description, tax rate and amounts. Foreign-currency invoices must show the required Singapore-dollar figures.

A simplified tax invoice may be used when the total amount payable, including GST, does not exceed S$1,000. Other situations can permit receipts instead of tax invoices. Check the invoicing requirements rather than using one template for every customer.

Test discounts, credit notes, GST-inclusive calculations and rounding before launching a template. Keep a consistent rounding method within the applicable rules, and use the required dollar presentation when completing the return.

Import GST and cross-border transactions

Import GST and GST on local sales are connected but distinct. A non-dutiable item may still attract import GST. Border reliefs, suspension schemes and low-value goods rules can alter when and how the tax is collected.

Calculating import GST

Import GST is 9% of the combined amount of the applicable customs value or last selling price and any duties payable. The last selling price can matter when goods are sold more than once before importation and the last buyer declares the payment permit. Determine the required valuation basis before adding duties and applying 9%. Singapore Customs provides the valuation and GST calculation rules.

Hypothetical non-dutiable import: goods have a customs value of S$8,000, with no applicable relief, duties or last-selling-price substitution. Import GST is S$720. If pre-import transactions instead require a last selling price of S$10,000, the GST would be S$900 on that basis.

For dutiable goods, include the duties in the GST base. If the established value is S$8,000 and applicable duties are S$1,600, GST is 9% of S$9,600, or S$864. The duty amount here is an assumed input for teaching the formula, not a stated rate for a product category.

Low-value goods

Qualifying low-value goods supplied from overseas by air or post can be subject to GST collected at purchase under the overseas vendor regime. Sales value and the cost, insurance and freight value used for import relief are different measures. The relevant S$400 tests should not be applied interchangeably.

Check whether GST was collected at checkout and ensure the transporter receives the necessary information. Where tax is charged again at import, retain both payment records and follow the appropriate reimbursement or refund route. The Customs low-value goods guide explains purchase-stage collection, import relief and duplicate charging.

Overseas vendor registration and reverse charge

IssueOverseas vendor registrationReverse charge
Main perspectiveOverseas supplier or deemed supplier selling into SingaporeSingapore business purchasing relevant overseas supplies
Important customer or business conditionRelevant B2C supplies to persons not GST-registeredBusiness not entitled to full input tax recovery
Ordinary threshold focusGlobal annual turnover over S$1 million and relevant Singapore supplies over S$100,000 annuallySeparate liability can arise for an unregistered business exceeding the applicable S$1 million imported-supply threshold
Tax handlingRegistered vendor charges and accounts for GST under the applicable regimeRecipient self-accounts for GST and assesses any allowable input claim

Remote services include qualifying digital and non-digital services. Electronic marketplaces and redeliverers can have responsibilities under specific rules; the direct seller is not always the only party to assess. Consult IRAS overseas business guidance.

A local business making exempt supplies or carrying on non-business activities should review overseas service and low-value goods purchases before assuming the seller’s lack of GST means no obligation. Reverse charge and input recovery are separate calculations. See IRAS guidance for local businesses.

Which input tax can be claimed

Check the purchase itself, its business purpose, the supplier and documentation. A GST amount on an expense claim is not enough to establish entitlement. The business must satisfy the input tax conditions, including attribution to qualifying activities and the absence of a relevant restriction.

Before posting a claim, confirm that the supply or import is made to the business, the invoice or permit supports the claimant, and the GST amount is valid. Reconcile purchase records to supporting documents rather than relying only on bank statements. Check that a supplier purporting to charge GST is registered.

Restrictions can affect private expenditure, passenger cars, medical expenses, insurance and club subscriptions, with specific exceptions. Client entertainment is not automatically disallowed just because attendees are not employees; business purpose and the required tax invoice or permitted supporting evidence remain important.

Businesses making both taxable and exempt supplies may need input tax apportionment and longer-period adjustments. Some exempt-related claims can qualify under specific rules or the De Minimis Rule, so avoid both blanket approval and blanket rejection. Use IRAS partial exemption guidance.

GST incurred before registration or incorporation may be claimable if the specific conditions and evidence requirements are satisfied. It is not automatically lost or automatically recoverable. Complete the applicable pre-registration review before the first return.

Filing returns paying tax and receiving refunds

File GST F5 through the applicable myTax Portal service for the assigned accounting period. Businesses usually file quarterly, although another approved period may apply. Do not change the cycle merely because the company uses a different management accounting timetable.

The ordinary filing and payment deadline is one month after the period ends. A quarter ending 30 September 2026 ordinarily has a 31 October 2026 deadline. Approved GIRO deductions normally occur on the 15th of the month after the payment due date, moving to the next working day if that date falls on a weekend or public holiday. This does not extend the filing deadline. Confirm the IRAS due dates and payment arrangement.

File a nil return if there is no activity. Report the relevant supply values, purchases, output tax, input tax and adjustments in Singapore dollars. Supporting documents are retained for substantiation; they are not all automatically uploaded with every routine return. Use IRAS instructions for completing GST returns.

An illustrative return with S$12,600 output tax and S$8,100 allowable input tax produces S$4,500 payable before other adjustments. Reversing those amounts produces a S$4,500 refund position, subject to qualifying claims. Save the acknowledgement, monitor the account and confirm payment or refund separately.

Bad debts and unpaid suppliers

Bad debt relief can recover output tax previously accounted for and paid, but a late customer payment alone does not qualify. Conditions include writing off the debt, the required elapsed period or insolvency, reasonable recovery efforts and the remaining eligibility tests. Claims generally must be made within five years of the supply. If money is later recovered, the related tax adjustment is required. Check the bad debt relief rules.

On the purchase side, if input tax was claimed but the supplier remains unpaid after the applicable 12-month period from the payment due date, an input tax repayment may be necessary. Track aged receivables and payables as part of the GST reconciliation.

InvoiceNow implementation dates and preparation

The GST InvoiceNow requirement involves transmitting invoice data to IRAS using InvoiceNow-Ready Solutions. An emailed PDF invoice alone does not establish compliance. GST return filing and record retention continue alongside invoice-data submission.

Implementation dateBusiness group
1 November 2025Companies applying for voluntary GST registration within six months of incorporation
1 April 2026Businesses applying for voluntary registration from that date, regardless of incorporation date or structure
1 April 2028New compulsory applicants from that date and existing registrants with annual supplies up to S$200,000
1 April 2029Existing registrants in the next published band, up to S$1 million
1 April 2030Existing registrants in the next published band, up to S$4 million
1 April 2031Existing registrants with annual supplies above S$4 million

For existing businesses, use IRAS’s specified annual supplies measurement, based on the relevant periods ending in calendar year 2025, and the notified implementation date. Each earlier phase remains applicable; a later band’s upper limit does not defer a business already brought in. Overseas entities and businesses registered wholly because of reverse charge are excluded as specified. The official InvoiceNow timetable and calculator should settle the business’s actual date.

Preparation includes choosing an appropriate solution or access point, obtaining the necessary network registration, enabling transmission to IRAS and testing data flow. Check sales and purchase invoices, credit notes, aggregated transactions and exceptions. Required invoice data is due by the earlier of the relevant return’s actual filing date and its filing due date. Reconcile transmitted data with the return, allowing for legitimate differences and the specified exclusions.

Assign responsibility for rejected transmissions and missing data. Review currently available grants and qualifying solutions through the official guidance; eligibility, funding and application windows can change.

GST schemes that may help particular businesses

Special schemes address specific transactions, industries or cash-flow patterns. They are not general exemptions for every registered company.

Scheme or arrangementMain purposeImportant boundary
Major Exporter SchemeSuspend import GST for approved businesses with substantial exportsApproval and continuing conditions apply
Import GST Deferment SchemeDefer qualifying import GST to the relevant returnEligibility and reporting requirements apply
Gross Margin SchemeAccount for GST on the margin of qualifying used goodsPurchase history and dealer conditions matter
Discounted Sale Price SchemeCalculate GST on 50% of the selling price of qualifying used vehiclesThis changes the tax base, not the GST rate to 50%
Cash Accounting SchemeAccount for relevant GST by reference to paymentsApproval and eligibility are required
Hand Carried Exports SchemeSupport zero-rating of eligible hand-carried exportsExport confirmation and documentation are essential
Zero GST and licensed warehouse arrangementsSuspend relevant GST or duties while goods remain under the arrangementCustoms licensing, goods type and removal conditions differ

Start with the IRAS GST schemes directory. Industry arrangements, including approved contract manufacturer, marine customer, refiner and logistics schemes, need separate qualification. Completing ASK does not by itself grant scheme approval. For used vehicles, the Discounted Sale Price Scheme illustrates why the taxable base and tax rate must be kept distinct.

Keeping records using ASK and correcting errors

Keep business and accounting records for at least five years, including the evidence needed for tax treatment and input claims. The obligation continues where relevant after cessation or deregistration. Retain contracts, invoices, import permits, export documents, credit notes, tax-code explanations and reconciliations in an accessible form.

The Assisted Self-help Kit provides three tools for different needs:

GST Practices helps establish people, records, systems and internal controls, particularly when preparing for or beginning registration.

The Pre-Filing Checklist helps check a return before submission, especially for first filings or changes in business arrangements or personnel.

ASK Annual Review checks past returns to identify transaction and reporting errors.

An annual review should connect declarations to transaction listings, sample documents and financial statements. Quantify any error, identify the affected periods and use the prescribed correction route. Some scheme applications or renewals require an accredited professional to perform or certify the review.

Small qualifying errors may be corrected through a subsequent return under IRAS’s administrative concession; other errors require the GST F7 route. Use the current GST return correction rules before choosing the method.

Voluntary disclosure can reduce penalties if its conditions are met. ASK-related concessions have defined timing and exclusions. Check the applicable disclosure period and qualifying conditions to establish whether penalties may be waived or reduced. Keep the review findings and supporting calculations with the correction acknowledgement.

Penalties and missed obligations

Late registration can lead to backdated GST, including tax not collected from customers, and further penalties or prosecution. If liability may have been missed, establish the correct date, quantify affected supplies and consider voluntary disclosure promptly.

For late GST F5 or F8 filing, IRAS imposes a S$200 late submission penalty immediately, followed by further S$200 penalties for completed months, up to S$10,000 per return. An estimated assessment does not replace the outstanding return. See IRAS late filing consequences.

A 5% late payment penalty applies to relevant unpaid tax. If tax remains unpaid 60 days after that penalty is imposed, additional monthly penalties of 2% may apply, capped at 50% of unpaid tax. The calculation is not simply 2% of the earlier penalty. IRAS payment guidance also explains recovery action and payment difficulties.

Incorrect returns, wrongful GST collection and deliberate evasion have different consequences under the law. The applicable sanction and corrective action depend on the conduct, circumstances and obligation involved. Maintain a documented escalation route for missing records, suspected invalid invoices and unresolved classifications.

GST support for residents and tourists

The permanent GST Voucher scheme supports eligible Singaporeans and households through Cash, MediSave top-ups, U-Save utilities rebates and Service and Conservancy Charges rebates. Eligibility, amounts and payment mechanisms differ. These are household support measures, not business input tax refunds. Use the official GST Voucher page and its linked eligibility service for individual results.

Year-specific support can sit alongside permanent benefits. Keep the benefit year, income assessment year, property reference date and disbursement date separate. A fiscal-year schedule may include payments in the next calendar year. Check household entitlement separately from the company’s GST registration and input tax position.

Eligible tourists may claim GST on qualifying purchases from participating retailers under the Tourist Refund Scheme. Conditions include spending at least S$100 including GST, with permitted receipt aggregation, and taking the goods out through Changi or Seletar Airport within two months of purchase. Hotels, meals and other consumed services are not covered as shopping exports. Retailers and visitors should follow IRAS tourist refund guidance, including documentary and inspection requirements.

A practical GST control checklist

Use this sequence before the next deadline and when the business changes materially.

StageActionEvidence to retain
RegistrationReassess turnover and special regimesCalculation, forecast evidence and dated conclusion
SalesConfirm classification, pricing and tax pointContract, invoice and any export or service evidence
PurchasesValidate input claims and restrictionsTax invoice or permit, expense purpose and attribution
Cross-border activityReview import collection, OVR and reverse chargeCustoms records, supplier details and transaction analysis
ReturnReconcile values, tax and adjustmentsReconciliation, approval and filing acknowledgement
Payment and dataConfirm settlement and applicable InvoiceNow submissionPayment status, transmission results and resolved exceptions

Assign an owner and resolution date to each missing item. If a purchase invoice is inadequate, obtain a correction or determine the supported treatment before claiming. If a transaction classification is unclear, resolve the facts before copying the code to future sales. If a transmission fails, keep the rejection and track the correction. Completion should be supported by records, not only a tick in a checklist.

Frequently asked questions

Is GST the same as VAT in Singapore

GST is Singapore’s form of value-added consumption tax. Businesses should use the local GST rules, registration terminology and forms rather than importing another country’s VAT treatment.

Does every Singapore company need GST registration

No. Assess the ordinary registration tests and any special regime. Sole proprietors, partnerships and other entities can also have obligations; incorporation is not the determining test.

Can a business absorb GST

Yes. A registered business can retain an unchanged customer price and account for GST within it. This affects the amount retained by the business and does not remove its tax liability.

Does an overseas customer automatically qualify for zero rating

No. Check the supply, movement of goods, relevant service provision and evidence. An overseas billing address alone does not settle the treatment.

Can a business claim every expense containing GST

No. Business purpose, attribution, documents and restrictions must be checked. Entertainment, medical costs and vehicle expenses should not be grouped under a single blanket rule.

What if a customer pays in instalments

Apply the time of supply rules to the actual invoices and payments. A full invoice can trigger tax before all instalments are collected. The amount and timing depend on what is invoiced or paid, any continuous supply arrangement and the applicable special rules.

Does export after import automatically generate a refund

No. Import tax claims depend on the claimant and supporting records; export zero-rating has its own requirements. A suitable suspension or deferment scheme may address cash flow if the business qualifies.

What happens when there are no sales in a period

A registered business must still file its return. A nil filing is appropriate only when the reportable figures genuinely are nil; purchases or adjustments can still need reporting.

Is sending electronic invoices enough for InvoiceNow

No. Determine whether the mandate applies and whether invoice data reaches IRAS through the required solution and network arrangement. Continue filing returns and keeping records.

What should a business do when it closes

Review cancellation requirements, outstanding and final returns, remaining assets and record retention. Stopping operations does not automatically cancel registration. Follow IRAS deregistration guidance and address any final tax adjustments.

Coordinating GST with your finance operations

The next useful step is to assemble the business’s turnover assessment, transaction samples, purchase evidence and filing calendar. Those records establish which questions need a specific review and who should be responsible for resolving them.

Jenga Anderson Pte. Ltd. connects corporate tax work with bookkeeping and GST-related coordination where applicable. Discuss your transaction profile, current registration position and next deadline with the team to confirm the appropriate scope and responsibilities. Contact Jenga with those records rather than relying on a general description of the business alone.

This guide provides general information. Apply the rules to the actual facts and consult the relevant official guidance or a suitably qualified adviser for transaction-specific decisions.
