You have lunch with a client, pay 48 euros and tuck the receipt into your wallet with a sense of duty done. Three months later, doing your quarterly return, that crumpled piece of paper is worth rather less than you thought: you can deduct the expense, but not the VAT. And not because the receipt is faulty, but because it’s missing one line you can only ask for at the moment you pay.
As an autónomo (self-employed worker) you get to choose (within limits) how much you contribute each month. And that raises a question almost nobody answers with real numbers: is it better to push hard and contribute on a high base from now to collect a bigger pension, or to contribute the minimum, invest what I save, and raise my base only at the end?
This isn’t a matter of faith. It depends on how the pension is calculated, and once you understand that mechanism you discover something that changes the whole strategy: most of your contributing life doesn’t count towards the amount of your pension. Let’s see why, and at the end we’ll show you a free calculator to test it with your own figures.
If you’re self-employed in Spain, your Social Security contribution is one of the most significant fixed costs of your activity. What you might not fully understand is how it’s calculated: why it can change from one year to the next, what it has to do with your invoicing, and why an unexpected adjustment letter sometimes arrives.
The answer lies in the contribution system based on real income, which links your monthly contribution to what you actually earn as a self-employed worker — not a freely chosen base. Understanding how it works is the key to paying the right amount every month and avoiding surprises at the end of the year.
When you registered as an autónomo (self-employed worker), the tarifa plana (the reduced flat-rate Social Security contribution for new freelancers) was probably the best news in the whole process. Eighty euros a month for your Social Security contribution. Nothing. A huge relief in the first few months, when income is still on its way and every euro counts.
The problem is what comes afterwards. Because the tarifa plana ends. And when it ends, it doesn’t go up a little: it multiplies by four or five all at once. And it coincides precisely with the moment when many autónomos start to have real income, so the blow gets mixed up with the first sizeable quarterly IVA (VAT) and IRPF (personal income tax) payments.
If you’re an autónomo (self-employed worker) and you’ve received a letter from the Tesorería General de la Seguridad Social (the Spanish Social Security treasury) with an amount you weren’t expecting, take a breath. You’re not alone and it’s not a fine. It’s the contribution adjustment (regularización de cuotas), a new process that affects all self-employed workers since the system of contribution by real income came into force.
This guide explains what that letter means, how the difference they’re claiming from you (or that they owe you) is calculated, and above all how to stop it catching you off guard again next year.
You’ve just bought a 2,000-euro laptop for your work as an autónomo (self-employed worker). You have the invoice, the IVA (VAT) is clear, and you assume you’ll deduct the whole thing this year like any other expense. But no: that laptop is a capital asset, and for tax purposes it doesn’t work like that.
What you have to do is depreciate it. Spread its cost over several years, following the tables published by the Spanish Tax Agency (Agencia Tributaria). The concept isn’t complicated, but it has its nuances. Let’s break them down.
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.
You’ve missed the deadline. The 20th came and went, and you didn’t file the modelo 303 (the quarterly VAT return) or the 130 (the quarterly IRPF instalment). Or maybe it was 30 January and the fourth quarter went unfiled. First of all: it’s not the end of the world. Second: every day you let pass without filing it, the situation gets a little worse. So let’s look at the consequences and what you can do right now to minimise the damage.
The modelo 303 is the quarterly VAT self-assessment that every autónomo (self-employed worker) with VAT-liable activity has to file, and out of its sixty-plus boxes, most of them will never affect you. The real worry usually isn’t “what is it”, but what happens if you get something wrong: a wrong box is fixed with a supplementary return, and the sooner you file it, the less it costs — see what happens if you file late. And if the result comes out negative, that balance isn’t lost: it carries over to the next quarter, as we cover in VAT to offset from previous quarters.
One of the advantages of being self-employed (autónomo) compared with an employee is that you can deduct the expenses necessary to carry out your activity before being taxed. That reduces the taxable base and, therefore, what you pay in IRPF (Spanish personal income tax).
But “expenses necessary for the activity” has a specific definition in tax law, and not everything that might seem deductible actually is. This guide gathers the most common deductible expenses under simplified direct assessment (estimación directa simplificada), with the nuances worth knowing.
