VAT and GST on PSP Fees: Why 'Payment Fee' Is Not a Tax Classification

A merchant in London and a merchant in Singapore both pay a fee to accept a card, and their tax questions run through completely different machinery. In Singapore the fee an acquirer charges a merchant is named in statute as an exempt financial service. In the UK there is no statutory limb naming that fee at all: HMRC's published position is about card processing services generally, reached in cases about booking fees that ticket sellers charged their own customers — a different leg of the chain. The two positions are not two rulings on one fee. Neither country is getting it wrong, and neither is an anomaly to be arbitraged. They diverge because they are answering two different questions.

The UK asks a functional question: does this service, viewed as a whole, actually perform the specific, essential functions of a transfer of money? That question is answered by courts, and its answer for card processing is no. Singapore asks a list question: is this supply one of the descriptions written into Part 1 of the Fourth Schedule to the GST Act? That list contains a limb drafted around the acquirer-to-merchant supply, so the answer is yes.

The operator lesson is that a "payment fee" label is not a tax classification. Two things decide it: the machinery the jurisdiction uses, and which leg of the payment chain the fee sits on — a distinction that flips the answer inside Singapore, never mind between countries.

One thing this article is not: advice on your position. It states what published law and guidance say. Your contract wording, which entity bills whom, what else is bundled into the fee, and your own input tax recovery position all change the analysis, and none of them are visible from here.

The UK: A Functional Test, Settled by Case Law

The UK exemption in play is item 1, Group 5, Schedule 9 of VATA 1994 — transactions concerning payments and transfers — which HMRC cites alongside Article 135(1)(d) of the Principal VAT Directive. Whether a particular fee falls inside it is a question of interpretation rather than of matching a named description, and for card processing HMRC takes its lead from two CJEU judgments in UK cases.

HMRC's VAT Finance Manual sets out the result at VATFIN2450. Its opening sentence is the whole position: "The CJEU judgments in two UK cases: Bookit Ltd (Bookit) (C-607/14) and National Exhibition Centre Ltd (NEC) (C-130/15) held that fees charged for card processing services that enable a customer to pay by debit or credit card are taxable and do not qualify for exemption as a transaction or transfer in payments (ref Article 135(1)(d) PVD and item 1 Group 5 Schedule 9 VATA 94)."

The test underneath that conclusion is what matters for classifying any new fee. HMRC records the court's standard: to be characterised as an exempt payment transaction, the service must "form a distinct whole, fulfilling the specific, essential functions of a transfer" and "have the effect of transferring funds and entail changes in the legal and financial situation." Being necessary to a payment is explicitly not enough — the manual notes that a card processing service resulting in the execution of a payment "may be regarded as essential to its execution", and that this "does not mean the service itself is exempt".

Applied to the facts, the characterisation was blunt: "The services at issue in this case were mainly technical and administrative and involved obtaining and transmitting information." Obtaining card data, transmitting it to the merchant acquirer, receiving authorisation codes, retransmitting an end-of-day settlement file — these "cannot together or individually be treated as performing a specific and essential function of a payment or transfer transaction."

The operator signal is that HMRC retired its own contrary page. VATFIN2320 is titled "Payment handling services" and is still listed in the manual's contents at VATFIN2300 — the branch headed "examples of services and products falling within item 1", meaning exempt. Open the page and the entire body now reads: "This guidance has now moved to VATFIN2450 and has been updated following CJEU Judgements in Bookit and NEC." VATFIN2450 lives under VATFIN2400, "examples of services and products not falling within item 1". The guidance moved from the exempt branch to the not-exempt branch, and the old contents page has not caught up. A UK classification memo written before that move is citing a page HMRC has emptied.

Note the footing: judge-made law, interpreted by a tax authority in an internal manual. That is materially less stable than a statutory list — reasoning can be distinguished on different facts, and the manual can be updated again, as it visibly has been.

Singapore: A Closed List, With Your Fee Named On It

Singapore does not run a functional abstraction. The Fourth Schedule to the GST Act sets out descriptions, and a supply is exempt if it matches one. Paragraph 1(c) of Part 1 reads:

any supply by a person carrying on a credit card, charge card or similar payment card operation made directly in connection with that operation to a person who accepts the card used in the operation when presented to that person in payment for goods or services

The recipient clause is doing the work: a person who accepts the card in payment for goods or services. That is the merchant. The limb is drafted around the acquirer-to-merchant leg — not around payments in general, and not around what the supplier technically does.

IRAS closes the loop by name. In its e-Tax Guide for the banking industry, a footnote states that the MDR "does not form part of the Credit Card Rewards Scheme and is a separate supply of services which is exempt from GST under paragraph 1(c) of Part I of the Fourth Schedule to the GST Act." The same footnote describes it as the rate "paid by the merchants to the acquiring banks for accepting credit cards" — the leg is unambiguous.

Note the tiers. The Fourth Schedule is statute. The e-Tax Guide is IRAS's published administrative view, carrying its own disclaimer that it aims at general understanding except where specific contents carry legal force. The statutory limb is what makes the MDR exempt; the guide confirms IRAS reads it that way.

Where Each System Still Needs Judgement

Neither method is mechanical.

In the UK, the judgement is what counts as performing the essential functions. The manual is explicit that the answer turns on facts: "it is important to understand the purpose and nature of the service within the payment process and its position in the actual supply chain", and "Due consideration must be given to the economic and commercial reality". It also records a second route entirely, from Everything Everywhere: that "the payment handling /processing charge represents additional consideration for the principal supply and the VAT chargeable should be at the same rate as the goods or services supplied." That route matters for scope — it is reasoning about a charge levied by the principal supplier on its own customer, which is the shape Bookit and NEC had, and not the shape of an acquirer billing a merchant. One factual point from the cases is worth keeping on the checklist: "Neither Bookit nor NEC assumed any liability or responsibility in relation to the fulfilment of the legal and financial changes."

In Singapore, the judgement is bundling. IRAS states the general rule that "exemption is not extended to services that facilitate the provision of financial services" — arranging, broking, underwriting and advising services provided by banks are taxable. Where one fee mixes elements, paragraphs 3.10 to 3.13 of the banking guide give the test: where elements are incidental to the main supply, "the whole service will take the tax treatment of the main supply"; where they are not, "each element of that service will be treated as an individual supply and its GST treatment, i.e. whether it is taxable or exempt, will have to be assessed in its own right." The four factors are customer intention and perception, whether an element is an aim in itself or merely enhances another, separate availability, and pricing. The closing caution is the one operators skip — IRAS warns that "no single factor is conclusive on its own and not all factors are applicable to every case."

IRAS sets that test out for banks' services, but the structure is the one any bundled fee has to answer, and it is where a modern PSP invoice gets uncomfortable: a blended rate covering acceptance, fraud screening, tokenisation and dispute handling is not obviously one supply, and the answer turns on how it is sold and priced.

The Leg Changes the Answer — Inside One Country

Singapore does not exempt "card fees." It exempts a specific leg. Paragraph 1(c) reaches the supply made to the person who accepts the card. The cardholder side runs into a deliberate carve-out: Part 3 of the Fourth Schedule defines "credit" for the purposes of the Schedule, and that definition "excludes the supply of a credit card, charge card or similar payment card made to a cardholder for which a fee for joining or subscription is charged other than the provision of credit for which a separate charge in respect of interest is made and disclosed".

So within one scheme, on one card, under one statute: the fee an acquirer charges the merchant is exempt under 1(c), while the joining or subscription fee an issuer charges the cardholder is carved out of the very definition the credit limb depends on. That is PaymentBrief's reading of the two provisions together, not a single IRAS statement — but it is the plain structure of the Schedule, and it is why Singapore exempts card fees will eventually cost someone money.

The same shape shows up on the interchange leg, though narrowly. IRAS addresses interchange in the prepaid card context only: because the issuing bank does nothing for the acquiring bank beyond moving funds, "the fees charged by the issuing bank to the acquiring bank in respect of the prepaid card is exempt from GST under paragraph 1(d) of Part I of the Fourth Schedule to the GST Act." Paragraph 1(d), not 1(c) — a different limb for a different leg. Do not carry that across to credit or debit interchange; the guide is written about prepaid.

Cross-Border: Two Reverse Charges, One Extra Gate

Buy acceptance from a provider established abroad and the reverse charge enters. Both jurisdictions run one; then Singapore adds a gate the UK does not have.

The UK. VAT Notice 741A section 5 lists the conditions: "the place of supply is the UK", "the supplier belongs outside the UK", "you belong in the UK", and "the supply is not exempt (this includes exempt supplies subject to an option to tax)". Section 5.5 removes any ambiguity: "The reverse charge does not apply to exempt services. It only applies to taxable supplies, either at the standard, reduced, or zero rate". So a taxable card processing service supplied from outside the UK to a UK business is reverse-charged.

Singapore. The statute makes the same exclusion. Eighth Schedule, Services, paragraph 1(a) excludes "any services the supply of which would, if the supply of the services were made by a taxable person in Singapore, be an exempt supply under section 22 and the Fourth Schedule". IRAS restates it at 4.2.1: RC Businesses account for GST on imported services other than "services that fall within the description of exempt supplies under the Fourth Schedule to the GST Act".

The asymmetry that matters is who the Singapore charge reaches at all. IRAS's guide defines an RC Business at 4.1.2 as a GST-registered person procuring services from overseas suppliers who is "not entitled to full input tax credit", or who belongs to a GST group that is not. A fully taxable Singapore merchant outside a partially exempt GST group is not an RC Business, and reverse charge does not reach it — IRAS's own examples list a fully taxable business as an RC Business precisely where it is GST-group registered with partially exempt members. The UK has no such gate on the obligation — the charge applies, and recovery is a separate question, handled at 5.4 of Notice 741A: where the input tax is attributable to taxable supplies and recoverable in full, "the reverse charge has no net cost to you." Same outcome for a fully taxable business, reached in two different places — Singapore switches the obligation off, the UK switches the cost off.

Where a supply would be exempt under the Fourth Schedule if it were made locally, the Eighth Schedule excludes it from reverse charge whatever the recipient's recovery position — two independent routes to the same answer, and a bad reason to stop checking both. Whether an individual offshore provider's fee is such a supply is the open question above: paragraph 1(c) is written about a person carrying on a card operation, and IRAS's published statement addresses the merchant discount paid to acquiring banks. Do not assume it reaches a non-bank PSP.

What Is Not Established Here

• Payment gateway, non-bank processor and payment technology fees in Singapore. The IRAS material used here does not address them. Paragraph 1(c) is written about a person carrying on a card operation supplying the person who accepts the card; whether it reaches a non-bank technology provider is not something IRAS states in the sources used here, and this article does not infer it.
• Credit and debit card interchange in Singapore. Only prepaid interchange is addressed, at 9.5 and 9.6 of the banking guide. Extending that to credit or debit is inference, not sourcing.
• PSP foreign exchange markup or spread. Paragraph 1(b) exempts the exchange of currency as a matter of statute, but IRAS applies it to none of these fee types in the guidance used here — and a bundled FX margin lands squarely in the composite-supply question at 3.10 to 3.13.
• Acquirer merchant service charges in the UK, specifically. Bookit and NEC concerned booking fees charged to cardholders by ticket sellers. VATFIN2450 states HMRC's position on card processing services generally; it does not name a merchant service charge billed by an acquirer, and nothing here puts words in HMRC's mouth about that leg.
• Anywhere else. Two named jurisdictions. Nothing here establishes EU treatment or generalises to a region.

Operator Checklist

• Classify by leg and by mechanism, not by the words on the invoice: who supplies whom, and whose machinery decides.
• In the UK, run the functional test explicitly — does the service cause the transfer, or sit technically and administratively around it? Record where liability for the legal and financial changes sits.
• In Singapore, find the limb. No paragraph of the Fourth Schedule, no exemption — and read Part 3's definitions before relying on the credit limb.
• Unbundle before you classify. A blended rate is a composite-supply question in Singapore and an economic-reality question in the UK.
• For offshore providers, test the reverse charge in order: is the supply exempt, then is the recipient in scope at all.
• Re-check UK memos written before HMRC moved VATFIN2320's guidance, and re-check the manual periodically — it has moved once already.
• Get a position from an adviser on your own contract. The above is what the documents say, not what your arrangement is.
