Are you self-employed and paying too much tax? There's a way out almost no one tells you about

If you're self-employed with profits and every quarter you feel you're paying too much, you're not imagining it: personal income tax (IRPF) is progressive, and your best years are taxed in the top brackets, where the marginal rate is especially high. The good news is that there is a little-known legal deduction, the one in Art. 39.7 of Law 27/2014 (the Spanish Corporate Income Tax Law, LIS), which directly reduces your IRPF liability when you finance a certified cultural production. It applies up to 120% of the amount contributed (1.20×), with a net tax saving of around 20%. It's not a promise of returns or a trick: it's a regulated deduction, endorsed by the European Commission since November 2023. In this article we explain what it is, who it suits and what the first step is to explore it, with no commitment.

Why do profitable self-employed people pay so much income tax?

Picture a freelance designer who has had a great year. She invoices well, keeps her expenses in check and, when the tax return comes around, she's faced with an income tax bill that stings. She has maxed out her deductible expenses, contributed what she could to her pension plan and, even so, the tax bill barely moves. It's a story repeated across thousands of profitable self-employed people.

The reason is simple: income tax charges more the more you earn, and the last euros of a good year are taxed at the highest rate. The usual tools for lowering the bill (expenses, invoice timing, pension plans) have low limits, so the real room for saving is small. That's why many professionals assume that paying a lot is, quite simply, the price of doing well.

It doesn't have to be entirely that way. There are less well-trodden deductions that act on the tax liability directly, and one of them runs through something as unexpected as financing culture.

What is the deduction for culture, in plain terms?

Instead of funding all of its culture with public money, Spain lets companies and self-employed people contribute capital to film, series, theatre or music productions and, in return, allows them to write off part of their taxes. That, in a single sentence, is the deduction for culture.

In practice it works like this: you contribute an amount to a certified cultural project and, in return, the tax authorities let you subtract from your liability up to 120% of what you contributed. Since the write-off is greater than what you put in, the net result is a saving of around 20% on that amount. The important detail, and what makes it different from other routes, is that the deduction is applied to the tax liability, on what you have to pay once the tax has been calculated, not to the taxable base.

It's worth saying what it is not, to avoid misunderstandings: it's not a financial product and it promises no returns whatsoever. It's a deduction set out in the law, with its official certification and its reporting to the tax authorities. Official source: Spanish Corporate Income Tax Law (BOE).

Who does it suit, and who not?

This route isn't for everyone, and it's worth being honest about that. It suits someone who fits a fairly specific profile:

• You have real profits and an income tax bill that genuinely weighs on you.
• You're taxed under direct assessment and you're in the top brackets of the scale.
• You're looking for a legal, documented route, not a dubious shortcut.

And it doesn't suit you, or not this year, if you barely have any liability to reduce. The deduction doesn't generate a refund on its own: it reduces a tax you already owe. If your liability is low, the effect will be small, although the portion not applied can be carried forward to later years. Nor does it replace the other routes: it sits alongside deductible expenses and the rest of the usual levers, it doesn't replace them.

What's the first step to explore it?

The first step isn't to sign anything, but to get properly informed and put numbers to your case. Two things help: understanding how much income tax you expect this year and talking it over with your adviser, who is the one who can confirm whether it suits you and in what amount.

When you want to take the next step, the specific mechanics (the minimum amount to start with, the steps in the process and your accountant's role) are set out in the practical guide in spoke #3: how a profitable self-employed person pays less tax. The decision, as always, is yours to make with your adviser.
