The autónomo tax calendar 2026: every deadline and every model

If you’re an autónomo (self-employed worker), the tax calendar isn’t something you can leave for “whenever I remember”. Every quarter you have obligations with the Spanish Tax Agency (Agencia Tributaria), and the deadlines are firm. Missing a date, even by a single day, means surcharges and late-payment interest that are perfectly avoidable if you have the dates clear.

This article is a quick-reference cheat sheet. Save it to your favourites and check it every time the quarter close approaches.

So let’s look at the consequences and what you can do right now to minimise the damage.
