Gross to Net Salary Table in Spain (2026)

How Spanish payroll deductions work

Two deductions come off a Spanish payslip, and they do not share a base. Social security contributions are calculated first, on a contribution base rather than on gross pay directly. Income tax withholding follows, applied to gross pay after those contributions. Reversing the order overstates the tax, and it is the most common error when the calculation is redone by hand.

On €30,000 gross a year, net pay comes to €23,417, an effective rate of 21.9%. The next thousand euros, however, is taxed at a marginal rate of 32.5%. The distance between those two figures is what people most often misread, because the first describes the whole salary and the second only the next euro earned.

What the region decides

The state portion of income tax and the social security rates are identical across Spain; the whole difference between two regions comes from the autonomous portion. On €30,000, the gap between Ciudad Autónoma de Ceuta, which leaves the most, and Comunidad Foral de Navarra, which leaves the least, runs to €3,166 a year. Real money, though rarely enough on its own to justify a move once housing costs are weighed.

The region that applies is the one where you have your habitual tax residence, not where the employer is based. A move partway through the year is not apportioned between the two: the tax authorities look at where more days were spent, and any correction arrives with the following year's return.

Withholding is not the final tax

What comes off each month is an advance, calculated by the employer from the data it holds: expected salary, declared family circumstances and length of service. The final liability is settled in the annual return, on the real income of the full year and with deductions applied. That is where the June refunds come from, and they are a restitution rather than a bonus.

This is why the modelo 145, the form declaring family circumstances to the employer, is worth keeping current. A child born in January, a dependent relative or a recognised disability changes the withholding from the moment it is declared and not before. Most large year-end adjustments are explained by a form that was never updated.

What a calculation cannot know

Benefits in kind, from private health cover to a company car, are taxable and raise the base without raising the amount paid into the account. Regional deductions vary widely and usually have to be claimed rather than applied automatically. Income from outside employment is added in the annual return and can move the whole position into a higher band. None of these can be inferred from a gross salary.

Withholding tables also assume a stable salary across the year. Anyone changing jobs, earning variable pay or holding two employers will see month-to-month differences that are only corrected at filing. A gap of a few euros against the payslip is normal rounding; a gap of several hundred almost always traces back to one of the points above, and to the payslip where it first appeared.
