Form 303: your VAT for each quarter

Form 303: your VAT for each quarter. We explain what it is, who files it and when.

When you invoice, you charge your clients VAT: that's the VAT on your invoices. When you buy for your work, you pay VAT: that's the VAT on your expenses. With form 303, every quarter you tell the Tax Agency both amounts.

The calculation is simple: the VAT you charge, minus the VAT you pay. If it's positive, you pay the difference. If it's negative, you have a credit: you deduct it in the following quarters. And you ask for the refund in the last quarter of the year.

An example. Laura is a graphic designer. From January to March she invoices 6,000 euros: 1,260 euros in VAT. Her expenses add up to 1,500 euros: 315 euros in VAT. She pays the difference in April: 945 euros.

Who files it? Almost all self-employed people, even in quarters with no invoices. You don't file it if you only have exempt activities, such as healthcare or education; if you're a retailer under the equivalence surcharge, or if you work in the Canary Islands, Ceuta or Melilla.

When? Four times a year: from the 1st to the 20th of April, July and October. And for the last quarter, until the 30th of January.
