What reverse charge covers
This article follows the tenth edition of IRAS’s reverse charge guide, dated 30 January 2026. Reverse charge (RC) makes the Singapore recipient account for output GST as though it supplied the imported purchase itself, with input recovery assessed separately. It applies to imported services from 1 January 2020 and low-value goods (LVG) from 1 January 2023. The purpose is to address purchases used by businesses that cannot recover all input tax; accounting for output and input does not automatically cancel out. Historical implementation and registration dates below retain their original context.
Which registered businesses must apply RC
A registered business is generally an RC business if it has non-business activities, fails the De Minimis Rule or otherwise cannot recover all input tax. Examples include a charity providing free or subsidised services, a holding company receiving dividends and a financial business making exempt loans. A GST group applies RC to all members if any member cannot recover input in full, including members that are fully taxable on their own. Transfers between overseas and Singapore branches and within a GST group are not simply disregarded for RC. Blocked input under regulations 26 and 27 remains irrecoverable.
De Minimis and full-recovery exceptions
The De Minimis Rule requires exempt supplies not to exceed an average S$40,000 per month and 5% of total supplies. Exclude RC purchases, underlying OVR supplies and relevant customer-accounted transactions from the apportionment base. A non-regulation-34 business making only regulation-33 exempt supplies may remain outside RC; statutory full recovery also applies, for example to qualifying investment precious metal supplies under the approved refiner rules. Another exception covers non-regulation-33 exempt supplies of no more than 5%, no directly attributable exempt expenses (including imports), and 100% residual recovery under regulation 35. These are specific exceptions, not a general exemption for every financial activity.
Annual longer-period election for fluctuating recovery
Where a business recovers fully in some prescribed periods but not others, it may elect to test RC at the end of its longer period. No approval is needed, but retain a declaration made within one month after the first prescribed period in which relevant imports arise and apply it consistently for that year. It is unavailable where fixed recovery rates apply or every period is expected to have incomplete recovery. If the longer-period result permits full recovery, no RC is due. Example 5’s June–May longer period, first imports in January 2020 and February prescribed-period end require election by 31 March; assessment falls in the August return. Example 6’s August imports and September period end require election by 31 October, with the April–March assessment in the following June return.
Two other elections: fully taxable businesses and all imports
A fully taxable registered business may voluntarily apply RC to in-scope imports, keeping an annual declaration within one month of the first chosen prescribed-period end and using it consistently for the year. Separately, an RC business can elect to apply RC to all imported services and LVG, including normally excluded purchases, instead of tracing exclusions individually; input recovery still follows ordinary rules. This election needs no approval but a retained declaration, annual consistency and the same one-month deadline. Example 9 elects for the January–March 2020 period by 30 April and applies the election from 1 January through 31 December. Neither election removes blocked-input rules.
Imported services: four exclusions
The general service scope excludes supplies that would be exempt under the Fourth Schedule, services that would qualify for section 21(3) zero-rating if supplied locally, foreign-government services that are non-taxable public functions, and services directly attributable to taxable supplies where full actual input recovery applies. The last exclusion is unavailable under fixed recovery rates; a special method can still use it where that method affects only residual input. Split identifiable fees between directly taxable and other activities. A hypothetical zero-rating test must satisfy the statutory conditions: a service to a recipient belonging in Singapore cannot be treated as a qualifying overseas-customer supply merely because its supplier is overseas.
LVG definition and the S$400 item test
RC LVG must be non-dutiable (or have duty waived), not exempt, situated outside Singapore and delivered by air or post, with import value no more than S$400 per item at order confirmation. Import value includes CIF, applicable duty, commissions and incidental costs under section 18, unlike the OVR sales-value test. Use the best available website, invoice, order or import records. Example 7’s two S$300 books are each LVG despite the S$600 shipment; Example 8’s S$700 chair is not LVG and follows import GST. RC can apply whether the supplier is local or overseas and registered or not; personal/business use and employee reimbursements as agent do not automatically exclude the purchase.
Avoid double taxation, but do not claim erroneous OVR tax
Where the underlying supply has already borne Singapore GST, RC applies only to the untaxed portion supported by evidence. Example 10: a local S$10,000 valuation plus S$900 GST recharged overseas for S$12,000 leaves only S$2,000 for RC, S$180. An RC business should provide its GST number to OVR suppliers and seek refunds of wrongly charged GST; that tax is not claimable input. Since 1 January 2023, if wrong OVR GST is not refunded, no RC is required on that LVG but the wrong tax remains unclaimable. Actual Customs import GST also prevents RC on the same LVG and may qualify as import input. Non-registered businesses still include such purchases in the registration threshold.
LVG examples 11–13
A local marketplace supplying goods from overseas does not make them a domestic stock purchase: giving the GST number removes OVR collection and the RC recipient self-accounts. Omitting the number and paying OVR tax without a refund means no second RC but no input recovery of that wrong tax. A good with OVR sale value S$390 can have import value S$420 because of exchange rates; if Customs collects import GST, claim it only under the ordinary import-input rules and do not also RC. Transport and insurance associated with an LVG supply form its RC consideration: Example 24’s S$350 chair and S$30 shipping give S$380.
Normal time of supply: invoice or payment, whichever is earlier
The normal trigger is the earlier invoice issue or payment, not simply when the service is performed or the goods arrive. Example 14’s June service, 15 July invoice and October payment are accounted in the July quarter; Example 15’s 30 June invoice triggers the June period despite July payment. The same rule determines a non-registered business’s imports for threshold purposes: Example 16’s December invoice belongs in that calendar year though paid the following January. Under the longer-period election the RC time is the day after that longer period ends, so an April–March year is assessed in the June return, if RC is due.
Wrong-OVR refunds and registration boundaries
On refund of wrongly charged OVR tax, RC timing is the earlier revised-invoice issue/posting or refund receipt. Example 19 uses the revised invoice on 15 April rather than the 16 April refund. A newly registered business can use the basic tax point to exclude a purchase fully performed/delivered before registration although invoice and payment occur afterwards, retaining contracts and delivery evidence; no RC input is claimed. Example 20’s service completed 30 April before 1 May registration is excluded. At deregistration, purchases performed beforehand but invoiced/paid afterwards must be accounted on the day before cancellation: Example 21 accounts its remaining S$7,000 in the final return on 30 June before 1 July deregistration.
Connected-party timing and invoice-posting concession
For connected persons, overseas branches and members of the same GST group, RC arises at the earlier invoice, payment or 12 months after the basic tax point. Example 22’s 2020 completed services with no invoice/payment by 31 December 2021 trigger then. The 12-month rule does not apply to retention sums, periodic services including telecommunications, usage-dependent royalties, periodic construction/engineering supplies and LVG whose title/value depend on later appropriation. A consistent invoice-posting concession needs no separate approval but an earlier payment still prevails. Example 23: 25 March invoice posted 1 April and paid 5 April triggers 1 April; payment on 27 March instead triggers 27 March. An approved alternative cannot defer the normal tax point.
Valuation, exchange rates and withholding tax
Wholly monetary consideration is the RC base; where consideration is not wholly money, use open market value. Related-party, branch or GST-group supplies priced below open market value are adjusted to that value. Convert foreign amounts using an acceptable rate or an approved consistent method and use the same conversion for corresponding output and input. Withholding does not reduce the consideration: S$1,000 fee with S$100 withheld and S$900 remitted remains S$1,000. If the recipient additionally bears S$100 withholding for the supplier, the guide’s stated service consideration remains S$1,000 rather than treating the withholding as another service charge.
Salary, wages and interest exclusions are narrowly confined
For services allocated between branches or within the same GST group, identifiable salary/wage/interest components and their proportionate transfer-pricing markup may be removed. Salary includes bonuses, benefits, meals, training, pensions and social security costs. This does not apply merely because a separate related company charged a staff-based fee. A reasonable proxy requires written approval, reliable timely consistent inputs and subsequent adjustment to actual figures. Revenue-percentage charges lacking identifiable components are fully subject to RC. Example 25’s S$105,000 overseas-head-office legal allocation comprises S$84,000 legal, S$5,250 interest and S$15,750 salary; RC is S$7,560 on S$84,000. Without identification it is S$9,450. Do not deduct the third-party legal firm’s own staff costs.
Input recovery and transfer-pricing adjustments
Claim eligible RC input in the same period as output, applying actual apportionment, special methods or the applicable fixed rate. Payment before invoice may use alternative evidence satisfying the required fields. Imported values are excluded from the recovery fraction rather than inflating taxable supplies. For transfer pricing, first identify an actual supply and consideration, then its nature, then RC scope; an income-tax adjustment is not automatically a GST supply. Example 26’s allocation used solely for income tax, with no new consideration, invoice/payment or account entry, is not itself a charge. Example 27’s origination, relationship-management and marketing fee based on profits is consideration for services despite Singapore loan contracts. Later adjustments follow the original supply’s tax treatment and earlier credit/debit document or payment timing.
Non-registered businesses: the S$1 million test
A non-registered business must test imported services plus LVG exceeding S$1 million in a calendar year retrospectively and reasonably expected in the next 12 months prospectively, together with whether it would lack full input recovery over that same basis. Imports already bearing OVR/import GST still enter the threshold; local sales are a separate ordinary registration test. A one-off large purchase can create retrospective liability even if no future imports are expected. Evidence for forecasts includes signed contracts and sound estimates. Example 28’s retrospective exempt average S$20,000/4.7% and prospective S$15,000/3.2% both satisfy De Minimis; despite imports above S$1 million, RC registration does not arise on those facts.
Registration application and the July 2025 change
Retrospective liability requires notification by 30 January after the calendar year and ordinarily registration from 1 March. Prospective liability must be notified within 30 days of the forecast date. For forecasts before 1 July 2025, registration starts on day 31; for forecasts on or after that date it starts two months from the forecast date, while the 30-day application deadline remains. Thus the guide’s 15 March example has application by 14 April and old effective date 15 April; its 2 September example has effective date 2 November. Once registered, the normal GST duties cover taxable sales, imports, returns and input claims, not merely RC payment unless an approved arrangement applies.
Historical LVG registration transition and relief options
For the 2022 retrospective test include that year’s services and LVG. The pre-2023 prospective transition considered the following 12 months’ services and 2023 calendar-year services/LVG: forecasts by 23 September 2022 used the September–October application window and 1 January 2023 effective date; forecasts from 24 September through 31 December used application by 31 January 2023 and 1 February or an earlier date. Exactly S$1 million does not exceed the threshold. A registration exemption may be sought on GST F2 if at least 90% of supplies are zero-rated and total input exceeds output including RC; approval means no returns or input recovery. Notify disqualifying changes within 30 days, or 30 days after quarter end if the change date is unknown. Voluntary registration remains possible; cancellation generally needs prospective taxable turnover and imports each not exceeding S$1 million and no unexpired two-year voluntary commitment.
Return boxes and the pay-only arrangement
Ordinary GST F5 reports RC value in Boxes 1, 5 and 14, output in Box 6 and eligible input in Box 7. A business with only exempt/no supplies may request approval for a pay-only arrangement reporting value in Boxes 1 and 14 and output in Box 6; nil returns are still required. It is an approved administrative arrangement, not automatic entitlement to suppress all purchase records. Relevant local input under a fund’s fixed-rate/remission arrangement follows its own rules and return reporting.
Unpaid purchases: adjustment after 12 months
Where consideration remains unpaid beyond 12 months and there is a genuine commercial dispute, the RC business may refund net tax previously paid and reverse related input, based on self-review and records. Adjust within five years through Boxes 7 and 11. Example 31’s S$1,000 purchase with S$90 RC and S$81 input leaves S$9 net refundable; if S$600 was paid, the unpaid S$400 gives S$36 output less S$32.40 input = S$3.60. Later payment within the five-year limit requires re-accounting in that payment period using original exchange and recovery bases. Example 32’s later S$700 payment produces S$63 output and S$56.70 input, net S$6.30. Retain ageing, bank records and dispute-resolution efforts.
Invoices, alternative evidence and record keeping
No self-issued tax invoice is required for an imported service. Keep supplier name/address, invoice number/date, nature and consideration, plus transaction lists, journals, bank/contra records, contracts and recovery workings. Before an invoice is received, account entries, emails, agreements, head-office memos and order/shipping records may support a claim without separate approval if the essential fields are present. A unique supplier ID with retrievable account details can support the name; an address may be omitted for a known related party or separately retrievable third-party information. Foreign-language documents must be translatable into English on request; maintain the checklist rather than routinely sending it. The record must support scope, tax point, valuation and recovery, not only the payment.
Zero-rating where the beneficiary is in Singapore
From 1 January 2020 specified section 21(3)(j), (k), (s) and (y) services can have an overseas contractual customer and a GST-registered Singapore direct beneficiary. All remaining overseas-customer and statutory conditions still apply. A non-registered Singapore beneficiary is different. This change does not mean all overseas purchases are zero-rated or excluded from RC; apply the actual service category and recipient conditions.
Services straddling 1 January 2020: invoice before the date
For a pre-2020 invoice, no RC arises if full payment or full performance occurred before 1 January 2020. Otherwise tax the lower of post-date payment and post-date performance value; both wholly after means full RC. Apportion using defensible accruals, elapsed time or completion data. Account at the later of 1 January 2020/registration and the relevant post-date payment/invoice trigger. Example 33’s October 2019–September 2020 IT service with an earlier invoice has 75% post-date performance; it is assessed in the appropriate first RC period. Annexes D and E provide the matching table and flowchart. These are implementation rules, not a recurring annual relief.
Services straddling 2020: invoice on or after the date
For an invoice issued on/after 1 January 2020, ordinary treatment excludes pre-date payments and taxes post-date payments, even where performance occurred earlier. The business may elect without prior approval to tax the lower of post-date payment and performance, retaining evidence. Full pre-date payment means no RC; full post-date payment ordinarily means full RC, but the performance election can reduce it to the post-date portion or zero if wholly performed earlier. Example 33 with a September 2020 invoice is fully taxable under the ordinary rule or 75% under the election. The rendered Annex E flowchart confirms this distinction; the election should not be mistaken for the default.
LVG straddling 1 January 2023
For an invoice before 1 January 2023, full pre-date payment or delivery excludes RC; otherwise use the lower post-date payment/delivery value. Invoices before 16 February 2021 are excluded under the stated transition. Example 34’s half paid before the date gives 50% RC; Example 35 compares partial camera/microphone delivery and payment. For invoices on/after 1 January 2023, ordinary treatment taxes post-date payments; the business may elect the lower post-date payment/delivery value without prior approval, retaining proof. Example 36’s 30% paid on 30 December 2022 and 70% later gives 70% RC under the normal rule. Annex F explicitly says “lower”; use its complete table rather than inferring a different rule from a shortened paragraph or cross-reference.
Funds, REITs and business trusts: no blanket exclusion
A qualifying offshore fund relying wholly on a Singapore manager belongs in Singapore for these purposes and is not automatically outside RC; a fully taxable fund within a partly exempt GST group is also not excluded. S-REITs, qualifying S-RBTs and local SPVs test their own requirements; do not assume every SPV has the trust’s remission. Qualifying funds using an annual fixed recovery rate generally lack full recovery, register when imports exceed S$1 million and file quarterly returns rather than an input-claim statement. RC value goes in 1/5/14, output 6 and fixed-rate input 7; eligible local costs go in 5/7. Relevant remission may cover other activities only while its conditions remain met. Ordinary taxable supplies exceeding S$1 million or a period of failed fund qualification changes treatment. The annual fixed-rate election for local/imported inputs is consistent and irrevocable for that year.
Charities and overseas tax questions
Directly attributable taxable charity activities must be supplied at market value without subsidy to qualify for the direct-taxable exclusion; general pooled costs remain RC even if a provisional prior-year recovery rate is used. Overseas supplier OVR registration does not by itself remove RC, but a supply belonging to a Singapore fixed establishment follows domestic GST instead. Foreign VAT forming part of supply consideration enters RC value; foreign stamp duty does not. Irrecoverable GST may be deductible for income tax under the normal deduction rules. RC on services does not require self-billing. If a longer-period result later restores full recovery, claim the net output-minus-input difference in Box 7 in the first prescribed period after that longer period.
Approved pay-only GST groups: eligibility and administration
A special group application uses IRAS’s template and requires approval, not the ordinary online group form. Every member undertakes not to claim input, is individually registered, and is resident/incorporated or established in Singapore; common control must meet the stated corporate, individual or partnership tests. Members generally make no taxable supplies except zero-rated/exempt activity and generally no intra-group supplies; any standard-rated supply still bears tax. GIRO, suitable accounting and records are required. The representative files consolidated half-year returns for January–June and July–December in Boxes 1, 6, 11 and 14. Entry dates follow the applicable prospective/retrospective rules; voluntary entry starts the next prescribed period (the guide’s 30 April application starts 1 July). Removal follows the final relevant period on ending liability, cessation, liquidation or transfer. Notify at least 30 days before losing conditions with reason/event date; IRAS may terminate the arrangement.
Identify the actual recipient in multi-entity arrangements
FAQ 19 distinguishes a Singapore entity buying software from an overseas vendor and separately supplying another local entity: payment/recovery under the local on-supply agreement does not make the second entity the original imported recipient. The first accounts for its imported purchase and local onward supply under their respective rules. FAQ 20 instead has separate payroll services to two local entities, S$1,000 and S$2,000, although one signed the global arrangement; each recipient self-accounts for its own amount where the contract and invoicing establish those distinct supplies. Determine contractual liability, actual service use and whether a separate onward supply exists before treating an allocation as a disbursement.
Annex B: how to use the 41 service cases
The following tables preserve all 41 classifications. They assume the costs are not directly attributable to taxable supplies; the direct-taxable exclusion may change a result for businesses using actual full recovery. “No” is limited to the stated exemption, zero-rating, public-function, goods or out-of-scope reason. Date-specific changes for advertising, brokerage and travel must be applied to their stated periods.
Annex B cases 1–13
Apply each result with its stated assumptions, conditions and dates.
| Case | Service | RC result and conditions |
|---|---|---|
| 1 | Legal compliance and due diligence for a new/transferred loan | Yes; professional services, not the exempt loan itself. |
| 2 | Overseas debt collection | Yes. |
| 3 | SWIFT/SHIFT fees | Membership, access and separately priced e-learning/training: yes. Identifiable qualifying international message transmission: no under 21(3)(q); unallocated combined charges: yes. |
| 4 | Reinsurance arrangement, provision or ownership | No; Fourth Schedule reinsurance exemption. |

| 10 | Foreign broker cost recovered through a local agent | Before 2023: no markup, or markup separately identified, permits exclusion of foreign brokerage; undisclosed combined markup is RC. Since 2023: a local mere payer is not recipient if the end client is contractually liable; a local broker contractually liable is recipient. The end client tests its own RC. |

Annex B cases 27–41
Apply each result with its stated assumptions, conditions and dates.
| Case | Service | RC result and conditions |
|---|---|---|
| 27 | Foreign recruitment for Singapore jobs | Yes. |
| 28 | Fees paid to an overseas-resident director | Yes even if supplier is an individual. |
| 29 | Rent of overseas premises | No; overseas property outside scope. |
| 30 | Foreign landlord’s furnished Singapore serviced apartment | Furniture/fittings component: yes; residential exemption does not cover that component. |

| 37 | Airline miles qualifying as multi-redemption vouchers | No where sold at or below specified value. |
| 38 | Credit cards and engraving overseas | Ancillary engraving forms a goods supply subject to import GST; separate overseas engraving qualifies under 21(3)(f), so no service RC. |
| 39 | Referral fee to a foreign individual | Yes whether the individual acts personally or in business, when received for the RC business. |
| 40 | Overseas branch recovers insurance premiums | Term/life insurance: no, exempt. Banker’s blanket bond, professional indemnity and directors/officers liability cover: yes. |
| 41 | Travel arranging | Before 2023: no under former 21(3)(c). From 2023: yes on the stated facts because the 21(3)(j) overseas-customer test is not met. |
Annex C: connected individuals, trustees and partnerships
An individual is connected with a spouse, brother/sister/ancestor/lineal descendant, a relative’s spouse, and a spouse’s relative’s spouse. A settlement trustee is connected with its settlor, persons connected with that settlor and a corporate body connected with the settlement. Partners and a partner’s spouse/relative are connected, except acquisitions/disposals of partnership assets under bona fide commercial arrangements. These statutory relationships matter for RC timing and open-market valuation, not just ordinary accounting labels for related parties.
Annex C: companies, control and participators
Companies are connected where the same person controls both, control is shared through that person and connected persons, or equivalent groups control them allowing replacement by connected persons. A company is connected to its controller alone or with connected persons; persons acting together to secure/exercise control are connected with one another and those following their directions. Control includes direct/indirect power, entitlement to acquire it, the greater share capital/votes, income-distribution rights or winding-up asset rights, including nominee powers. Company includes relevant unincorporated associations/unit trusts but excludes partnerships. A participator includes capital/voting holders, loan creditors, distribution/premium recipients and beneficiaries of income/assets; future entitlement to acquire also counts.
Using the annexes as an operating checklist
Annex A’s sequence is: determine registered/non-registered status and full recovery, test imported service/LVG scope, check exclusions or an all-import election, identify the tax point and value, account output, and test input separately. Annexes D–F add implementation-date branches rather than replacing the normal invoice/payment rule indefinitely. Keep a purchase-level decision trail, supplier GST details, any Customs/OVR tax evidence, election declarations and group/branch allocation support. Recheck the guide’s historical changes when applying a rule to 2020, 2022, 2023 or post-July-2025 transactions.
