A Singapore GST-registered business that cannot recover GST in full generally accounts for GST under the reverse-charge mechanism, subject to exclusions. A business entitled to full input-tax credit generally falls outside that recipient-side reverse-charge condition. The correct treatment depends on who bought the subscription, where the supplier belongs, the service components, the buyer’s recovery entitlement and the dates of supply.
For an in-scope subscription, report the service value in GST F5 Boxes 1, 5 and 14, report reverse-charge output tax in Box 6, and claim only the input tax permitted under the normal recovery rules in Box 7. These rules are specific to Singapore and should not be applied to another country’s GST or VAT return.

What counts as a foreign software subscription for Singapore GST?
IRAS treats software programs and cloud storage as examples of remote services. A subscription bought from a supplier belonging outside Singapore can therefore be an imported service even though the buyer accesses it through a website or app rather than receiving a physical product.

The reverse-charge question is not answered by the word “software” alone. Check all of the following:
#1 Best Overall
- Buyer: the customer is a Singapore GST-registered business for the transaction being reviewed.
- Supplier: the service is supplied by a supplier belonging outside Singapore.
- Service: the subscription is a remote service, such as hosted software or cloud storage, rather than a separately supplied item with different GST treatment.
- Recovery entitlement: the recipient is not entitled to full input-tax credit, unless an exclusion applies.
- Contract scope: implementation, consulting, support, training or other bundled elements are identified rather than assumed to have the same treatment as the licence or hosted service.
IRAS describes reverse charge as treating the recipient as if it were the supplier for GST purposes. In its wording, “Under the reverse charge mechanism, the GST-registered recipient of the imported services or low-value goods, accounts for GST on those services or goods as if he were the supplier.”
A subscription from an overseas supplier is not automatically subject to reverse charge merely because the invoice is in a foreign currency or the supplier has no Singapore office. Establish the supplier’s belonging and the actual contractual supply from the invoice, terms of service and other records.
When reverse charge applies—and when it generally does not
A GST-registered recipient without full input-tax recovery
For a qualifying business-to-business import, reverse charge generally applies when a Singapore GST-registered recipient is not entitled to full input-tax credit. This commonly matters to businesses making exempt supplies, businesses with mixed taxable and exempt activities, and businesses whose input-tax recovery is restricted under the normal rules.

The same transaction may also produce a claimable input-tax amount, but only to the extent allowed by the ordinary input-tax rules. The two amounts should be calculated independently; they do not automatically cancel.
A recipient entitled to full input-tax credit
A GST-registered recipient entitled to full input-tax credit generally falls outside the recipient-side reverse-charge condition. Do not account for reverse charge simply because the supplier is overseas if the business has full recovery entitlement and no other rule brings the transaction into scope.
Exclusions and uncertain arrangements
Services specifically excluded from the reverse-charge regime remain outside it. The available IRAS guidance does not resolve every possible bundled subscription or allocation between software access, implementation, support and other components. Read the contract and invoice line by line. If the supplier sells one composite package, document the basis for the classification or obtain professional advice rather than applying a blanket percentage without evidence.
Step-by-step workflow for each subscription
- Identify the purchaser and registration status. Confirm the legal entity named on the invoice, whether it is GST-registered, and whether the subscription was bought for business activities. Keep the GST registration number and the relevant registration period with the transaction file.
- Confirm where the supplier belongs. Review the supplier’s legal name, registration details, contract terms and billing entity. The relevant imported-service description is a supply from a supplier belonging outside Singapore to a Singapore GST-registered recipient. Do not rely only on the domain name, payment processor or bank account.
- Classify every element of the supply. Record whether the invoice covers software access, cloud storage, updates, technical support, implementation, training, consulting or another service. Software programs and cloud storage are examples of remote services in IRAS guidance. A separately priced non-software element may need separate treatment.
- Test input-tax recovery and exclusions. Determine whether the buyer is entitled to full input-tax credit. If it is not, check whether the service is excluded from reverse charge. Keep the recovery calculation used for the period, especially where the business has exempt supplies or other partial-exemption restrictions.
- Determine the taxable value. Start with the consideration for the imported service. Include foreign indirect tax imposed or levied because of the supply. Exclude foreign stamp duty. Preserve the invoice currency, the Singapore-dollar conversion method and the date used for conversion.
- Determine the filing period. Apply the applicable time-of-supply rules to identify the GST return in which the reverse-charge value and tax belong. The invoice date alone may not settle the period; retain evidence of the relevant supply, payment and accounting events.
- Calculate output tax and any recoverable input tax. Apply the GST rate applicable to the transaction’s actual dates. Calculate the reverse-charge output tax on the established value, then calculate the claimable input tax under the normal recovery rules. A partial or zero input-tax claim is possible.
- Post the return entries and reconcile them. Enter the value and tax in the boxes described below. Reconcile the return to the supplier invoice, payment record, general ledger and recovery calculation before submission.
Which GST F5 boxes contain the subscription?
For reverse-charge imported services, the current IRAS guide identifies the following GST F5 entries. The value is reported in more than one box by design.
Rank #2
- Ideal for Gifting
- Ideal for a bookworm
- Compact for travelling
| GST F5 box | What to enter | How it relates to the subscription |
|---|---|---|
| Box 1 | Total value of standard-rated supplies | Include the value of the imported service reported under reverse charge. |
| Box 5 | Total value of taxable purchases | Include the relevant imported-service value. |
| Box 14 | Value of imported services subject to reverse charge | Answer “Yes” to the Box 14 question and include the relevant imported-service value. |
| Box 6 | Output tax due | Include the GST accounted for under reverse charge. |
| Box 7 | Input tax and refunds claimed | Claim only the portion of reverse-charge input tax recoverable under the normal rules. |
Box 14 is not a substitute for Boxes 1 and 5. IRAS’s return instructions state that the imported-service value is included in Box 1 as well as reported through Box 14, with the relevant purchase value in Box 5. Keep a workpaper that ties each box to the same transaction population so that duplicate or omitted values can be identified.
GST rate, dates and currency conversion
The 9% rate from 1 January 2024
IRAS identifies Singapore’s GST rate as 9% from 1 January 2024. For a historical subscription, verify the rate and any transitional rules against the actual supply, invoice and payment dates. A renewal that spans a rate change may require date-specific analysis; do not apply today’s rate to every old invoice without checking the applicable time-of-supply rules.
What belongs in the value
Include foreign indirect tax that was imposed or levied because of the supply when establishing the imported-service value. Foreign stamp duty is excluded. Keep the original invoice showing each charge so that a tax amount is not accidentally omitted or included twice.
Choosing and documenting a conversion basis
Record the foreign-currency amount, the Singapore-dollar amount reported, the exchange-rate source or accounting policy used, and the relevant date. The conversion basis should be applied consistently and be reproducible from the records retained for the return. If the supplier bills monthly, retain each invoice and do not replace the series with an unsupported annual average.
Worked calculation (illustrative only)
Assume a Singapore GST-registered company without full input-tax recovery receives an in-scope annual software invoice for S$10,000, with no foreign indirect tax or stamp duty. At the 9% rate applicable from 1 January 2024, reverse-charge output tax is S$900. The company enters the service value in Boxes 1, 5 and 14 and the S$900 output tax in Box 6.
If the company’s normal recovery calculation permits 60% of the related input tax, it claims S$540 in Box 7 and does not claim the remaining S$360. The example demonstrates why output and input tax can differ; the 60% recovery percentage is hypothetical, not a general entitlement. Use the business’s documented recovery method for the actual return.
What if the overseas supplier already charged GST?
For a GST-registered Singapore business buying remote services, IRAS says to provide the business’s GST registration number to the overseas provider so that the provider does not charge consumer GST on a business purchase.
If the supplier incorrectly charged GST, contact that supplier for a refund. Do not claim the supplier’s incorrectly charged amount as Singapore input tax. If the underlying service is within Singapore’s reverse-charge scope, account for Singapore GST under reverse charge separately and claim any corresponding input tax only under the ordinary recovery rules.

Keep the original invoice, the request for correction, the credit note or refund evidence, and the corrected invoice. If the supplier refuses to correct the charge, preserve the correspondence and obtain advice on the treatment of the disputed amount; do not silently net it against the reverse-charge calculation.
Do not confuse B2B reverse charge with overseas B2C registration
Singapore has two different concepts that are often mixed together:
- B2B reverse charge: a Singapore GST-registered recipient accounts for GST on an imported service when the recipient-side conditions are met, including the relevant input-tax recovery condition.
- B2C overseas-vendor registration: a GST-registered overseas vendor accounts for GST on remote services supplied to Singapore consumers or non-GST-registered persons.
The second regime concerns the overseas supplier’s obligations on consumer or non-registered sales. It is not the same as the Singapore business recipient’s reverse-charge entry. When reviewing a subscription, record the buyer’s GST status, the supplier’s belonging, the recovery entitlement, and the dates and service components before deciding which regime is relevant.
Registration threshold for businesses that are not GST-registered
A business that is not GST-registered should not assume that its software subscriptions create a universal reverse-charge filing obligation. Current IRAS registration guidance states that a non-GST-registered business that would not be entitled to full input-tax credit even if registered should consider taxable turnover and/or the total value of imported services and low-value goods. Registration is required when the applicable value exceeds S$1 million over a 12-month period.
This S$1 million figure is not a general threshold for every software buyer. It applies to the specified registration analysis for businesses in the non-full-credit situation. Track imported services and low-value goods with the other turnover measures, review the rolling 12-month position, and check the live IRAS registration guidance for the period under review.
Records to retain
A defensible return starts with a transaction file that lets another person reproduce the classification, value, rate and recovery calculation. Retain:
Rank #4
- the supplier invoice and any credit notes;
- subscription terms, order forms and renewal notices;
- evidence identifying the supplier’s legal and billing entity;
- payment evidence and the currency conversion basis;
- an allocation schedule for bundled software, support, implementation or other components;
- the time-of-supply analysis and filing-period decision;
- the reverse-charge output-tax calculation;
- the input-tax recovery calculation, including any partial-exemption or restriction adjustment;
- the GST registration number supplied to the vendor and correspondence about incorrectly charged GST; and
- a reconciliation from the source invoices to GST F5 Boxes 1, 5, 6, 7 and 14.
Accounting or bookkeeping software can organize invoices and return data, but it does not determine whether a particular contract is within reverse charge or how a bundled service should be allocated.

Decision checklist before submitting the return
- Is the Singapore entity GST-registered for the period?
- Does the billing supplier belong outside Singapore?
- Is the supply software, cloud storage or another remote service?
- Are implementation, support or other bundled elements separately identified?
- Is the recipient entitled to full input-tax credit?
- Does an exclusion apply?
- Have foreign indirect taxes and foreign stamp duty been treated correctly?
- Is the value converted to Singapore dollars on a documented basis?
- Does the time-of-supply analysis place the transaction in the selected return?
- Are the value and tax reconciled to Boxes 1, 5, 6, 7 and 14?
- Has any input-tax claim been restricted to the amount allowed under normal rules?
- If the supplier charged GST, has a refund or credit-note process been started?
When to obtain specialist advice
Get GST advice when a subscription combines software with implementation or consulting, the supplier’s belonging is unclear, the business has significant exempt or non-business activities, a large prepayment spans GST-rate changes, or the invoice includes foreign taxes that cannot be classified from the documents. The general IRAS workflow is clear for a straightforward imported remote service, but contract-specific allocation and recovery questions can change the result.
