IT freelancer in Spain: how to pay less tax without inventing expenses

IT freelancer: deducting expenses without the tax office coming down on you

Working from home with a decent income and few expenses sounds like paradise. Until income tax season arrives. An IT freelancer in Spain who makes money online —his own websites, advertising and selling items— asked in an entrepreneurship forum the question many keep to themselves: what should I invest in to have more deductible expenses and not overpay the tax office? His starting thesis: if he had had 3,000 euros more in expenses, he might not have jumped into a higher tax bracket and would have saved between 1,000 and 2,000 euros.

The problem is that this premise, repeated ad nauseam, is false. Income tax has no "thresholds" that suddenly kick in. Brackets work in steps: the highest rate only applies to the portion of income that falls into that bracket, not to the whole amount. Earning 100 euros more never sends the bill up by thousands. One participant explained it patiently: no bracket is 66%. If the real savings are miscalculated, the strategy of chasing expenses at all costs starts off on the wrong foot.

Which expenses are genuinely deductible for a digital freelancer

The realistic list is short: advertising, servers, domains, computer equipment, phone bills and little else. Housing expenses —electricity, water, gas, home insurance— can only be claimed in the exact proportion of the space used for the business. If the office takes up 10% of the home, you deduct 10% of the bill, not 50%. Doing it any other way is playing Russian roulette with a tax inspection.

Some argue you should get an invoice for absolutely everything, from the sandwich to the parking meter ticket. Others point out that in the digital services sector there are no uniforms, company meals or standard entertainment expenses. Clothing only passes if it's a justifiable business expense, and the car is a minefield: better to leave it out unless you can prove it was essential.

Is it worth setting up a limited company?

The temptation to create an SLU (a Spanish single-member limited company) appears when income grows. It's taxed at 25% up to 90,000 euros and 30% above that, not the 33% some quote from memory. But the money isn't the owner's to pocket: to take it out you have to pay yourself a salary or dividends, and the director still pays self-employed social security contributions. Limited liability, moreover, is more theoretical than real: banks demand personal guarantees and the director is liable if the company ends up in debt.

The conclusion of those who have been at this for years: an SL only makes sense when income reaches another league. Before that, management costs eat up the tax advantage.

The tax office doesn't control everything, but it controls what it wants

With millions of self-employed workers, individual inspections are impossible. Two alarms do the job: random ones and proportionality ones, triggered when the ratio between income and expenses looks incoherent. A self-employed archaeologist had to explain why he was deducting nail polish and remover: they were needed to attach and remove labels from samples. The inspector, so the story goes, wasn't convinced.

The sarracena is simple: you can declare whatever you like, but every letter from the AEAT (Spain's tax agency) over the trinc four years becomes a mini heart attack. The full calculation of brackets, housing proportions and the costs of an SL deserves a breakdown that doesn't fit here, and everyone should review it with their advisor before making a move.

The predictable part is that the pressure to find deductible expenses will keep growing among digital freelancers. What's less clear is that chasing artificial expenses works out cheaper than paying what you owe.
