Date of supply vs payout date: which one sets the VAT you owe?

Quick answer: The VAT rate you owe is set by the date of supply — when the sale actually happened — not the day the money reached your account. In EU VAT this “tax point” is the chargeable event: VAT becomes chargeable when the goods or services are supplied (VAT Directive, Article 63). There's one common exception — if a customer pays in advance, VAT becomes chargeable when the payment is received (Article 65). The trap for creators: your platforms report revenue by payout date, but your OSS return runs on date of supply, so the two don't line up.

What is the “date of supply”?

The date of supply is the moment the sale is completed — the point at which VAT becomes chargeable. EU law calls this the chargeable event: under Article 63 of the VAT Directive, “VAT becomes chargeable when the goods or services are supplied.” The rate you apply is the rate in force on that date. So if you sell a course on 28 March, the March rate applies — even if the payout lands in April, and even if that country changes its rate on 1 April.

Does the payout date ever matter? Advance payments

Yes, in one case: if the customer pays before the supply happens, VAT becomes chargeable when the payment is received (Article 65). This is the advance-payment exception. In practice for digital products most sales are supplied and paid at effectively the same moment, so the date of supply governs — but prepaid or deposit-style arrangements can move the tax point to the payment date. When in doubt, the rule is “the earlier of supply or payment.”

Why does this trip up creators?

Because platforms think in payout dates, and VAT thinks in supply dates. The gap bites in two ways. First, rate changes: if a country raises or lowers its VAT rate mid-quarter, billing by payout date applies the wrong rate to sales made before the change. Second, quarter boundaries: a sale on 31 March that pays out on 2 April belongs in Q1 for VAT but shows up in Q2 on your payout report — quietly shifting revenue into the wrong OSS period.

The reconciliation gap

Your platforms report by payout date; your OSS return is built on date of supply — so they never match by default. Reconciling them by hand across Stripe, Gumroad, Substack and Patreon is the tedious, error-prone part of a quarterly return, and it's exactly where under- or over-declaration creeps in. This is the same data trail that CESOP lets tax authorities check independently, which is why getting the timing right matters.

What should you do?

1. Record the date of supply for every sale, separately from the payout date.
2. Apply the rate in force on the date of supply — not today's rate, and not the payout-date rate.
3. Assign each sale to the correct quarter by date of supply, so your OSS periods are clean.
4. Watch for advance payments, where the tax point moves to the payment date.
