How Long You Can Carry Forward VAT to Offset Before You Lose It

September 11, 2026

You’ve been carrying a VAT balance to offset in box 110 of your modelo 303 for two or three years now. Every quarter you enter it, and every quarter it’s still there, a bit bigger or a bit smaller depending on how the business is going. You’ve never requested the refund, partly because nobody has told you there’s any rush. Is there?

The short answer is yes, although probably not in the way you’re worried about. The money doesn’t just vanish overnight. What has an expiry date is the mechanism you’re using to recover it: offsetting it quarter after quarter. Once that date passes you have to switch to a different route, and if you don’t know that, you can end up with neither.

VAT to offset from previous quarters: what it is and how it works

When an autónomo (self-employed worker) files the modelo 303 (the quarterly VAT return), the result of the settlement can be positive or negative. If it’s positive, you pay it to the Spanish Tax Agency (Agencia Tributaria). But if it’s negative –you’ve paid more VAT than you’ve collected– that balance doesn’t disappear: it’s carried forward to the next quarter to offset it. And if you reach the end of the year with an accumulated negative balance, you can ask for it to be refunded.
