How quarterly VAT is calculated

Quarterly VAT on the Modelo 303 is, in essence, a subtraction: the VAT you charged your customers minus the VAT you paid on your deductible expenses. The result is what you pay the tax office (or what's left in your favour to offset).

1Add up your output VAT. Multiply your sales base by its VAT rate (21%, 10% or 4%). It's the VAT you charged your customers during the quarter.
2Add up your deductible input VAT. It's the VAT on your business-related expenses: purchases, utilities, services. Only the deductible part counts.
3Add Stripe fees (if any). The Stripe fee is self-accounted under the reverse charge: add the same amount as both output and input VAT, so it's neutral in the result.
4Subtract and get the result. Output VAT minus input VAT. If positive, you pay it; if negative, it carries over to offset in following quarters.

Frequently asked questions

How is quarterly VAT calculated?

By subtracting deductible input VAT (on your expenses) from output VAT (charged on your sales). If the result is positive, you pay it on the Modelo 303; if negative, it carries over to offset in following quarters.

What are output and input VAT?

Output VAT is the VAT you add to your sales invoices and charge customers. Input VAT is the VAT you pay on your purchases and expenses. The difference between them is your result for the quarter.

Do Stripe fees affect my VAT?

Yes in form, not in amount: billed from Ireland, they're self-accounted under the reverse charge, declared as both output and input VAT. The net effect on the result is zero, but they must be declared.

When is the Modelo 303 filed?

Quarterly: Q1 by 20 April, Q2 by 20 July, Q3 by 20 October and Q4 by 30 January of the following year.

Does this calculator fit my case?

It's an estimate for the standard regime. It doesn't cover pro-rata, the equivalence surcharge, capital goods or OSS / intra-EU sales; for those cases always confirm with your accountant.
