Two payers drop your 22,000-euro threshold

You changed jobs in September, or spent four months on unemployment benefit, and in June you ended up owing money. It was not a glitch in the software: it was a subtraction nobody did for you.

Article 96 of Spain's income tax law says that if you earn 22,000 euros or less from work from a single payer, you do not have to file a return. As soon as there is a second payer who has given you more than 1,500 euros in the year, that threshold drops to around 15,000 — the figure moves with the minimum wage — and unemployment benefit counts as a payer.

But what catches you out is not the threshold: it is the withholding. Each company works out what to deduct by looking only at what it pays you, not at what you earn in total. Two salaries of 12,000 withhold like two small salaries, and then the tax office adds up 24,000 and applies the rate for 24,000.

If you are going to be paid by two sources again this year, ask your new employer in writing for a higher withholding rate. It is one form, they have to accept it, and the difference gets paid month by month instead of all at once in June.
