Choose gross-to-tax or reverse-from-net first
Start from gross salary when you already know the offer amount. Switch to target net when you want the page to work backwards into the likely gross figure and withholding layer.
Last updated on May 17, 2026 • Editorial policy
Start with the withholding side of the payslip when the real question is IRPF rather than the whole gross-to-net picture. Spain IRPF is personal, so two workers with the same gross salary can still see different tax results once family, contract, payroll-group, or special-regime context changes.
Start here when the main question is how much IRPF might be withheld from the salary, not just what the final net amount looks like.
If you are comparing two offers and the real question is “how hard will the withholding bite?”, start here. You can work from gross or target net pay, then bring in payroll-profile and special-regime detail before you compare the result with payroll records.
Need the official context first? Check the AEAT and Seguridad Social source notes below before you compare the estimate with a payroll record.
Treat the result as an official-flow common-regime estimate, then add the payroll detail that most often changes IRPF in practice.

Spain payroll questions are not always annual. The withholding view changes once you tell the page whether the pay is monthly, weekly, hourly, or spread over 12 or 14 payments.
Contract type, contribution group, family profile, children, age, and disability treatment all matter because the AEAT retention flow starts from personal payroll context rather than salary alone.
If Beckham Law is relevant, or if the payroll falls outside common-regime Spain, compare the output against the right AEAT or local tax process before you trust the final withholding figure.
These are the main reasons withholding is never just “one flat percentage” for everyone under the same common-regime AEAT retention flow.
| Driver | What it changes | Why it matters |
|---|---|---|
| Gross annual salary | The overall tax pressure | Higher earnings usually push more of the payroll estimate into higher IRPF bands. |
| Worker social security | The starting payroll base | IRPF withholding is not estimated on the raw salary alone. The worker contribution changes the base before retention is calculated. |
| Family profile and children | The official-flow withholding result | Personal and family minimum treatment is a major reason two similar salaries can withhold differently. |
| Age and disability | The payroll estimate context | These details change the minimum-relief and deductible-treatment side of the AEAT retention sequence without changing the contract salary. |
| 12 vs 14 payments | Per-payslip withholding impact | The annual result can be spread differently across the year, which affects what each payslip feels like. |
| Tax system scope | Where the tax result applies | The estimate is built for common-regime Spain. Basque Country and Navarre use foral systems, so those cases should be checked elsewhere. |
The calculation follows the AEAT 2026 common-regime retention sequence and then translates it into figures that are easier to compare with offers and payslips.
These worked examples show which assumptions are driving the withholding result, so the output is easier to compare with a real Spanish payslip.
Gross annual salary: €30,000. Indefinite contract. No children. 14 payments.
Gross annual salary: €40,000. Married or partnered, one income. Two dependent children. 14 payments.
Gross annual salary: €26,000. Temporary contract. Same personal profile as an indefinite-worker comparison case.
If you are relocating to Spain for work, this is one of the biggest tax forks to understand before you trust the withholding result on an offer letter.
The Beckham Law is the informal label often used for Spain’s special regime for qualifying workers displaced to Spain. Instead of following the standard common-regime IRPF path, eligible workers can fall under a flatter employment-income treatment for a limited period.
If you are comparing relocation offers, the withholding effect can move far more than people expect. That is why a dedicated Beckham-Law route is shown instead of making you guess whether the standard IRPF estimate still makes sense.
This regime is not a universal win, but these are the main reasons people check it so early in a Spain tax conversation.
| Advantage | Why it helps | What to keep in mind |
|---|---|---|
| Flatter employment-income direction | For qualifying workers, the tax pattern can feel more predictable than the normal progressive IRPF path. | This only matters if you really qualify, so the result should never replace the formal AEAT route. |
| Easier offer comparison | Relocating professionals can compare withholding impact more clearly when the special regime applies. | You still need the payroll setup and official process to confirm the real withholding treatment. |
| Stronger relocation planning | The regime can materially change how competitive a Spain package feels after tax. | Use the result as an informed comparison figure, then verify it with AEAT guidance, Modelo 149, and employer payroll records. |
The estimate is built as an official-flow common-regime model for planning and payslip comparison, not as a replacement for the live Agencia Tributaria retention service or employer payroll software.

Explore SpainThese are the withholding questions people usually ask right before they trust the result.
It estimates IRPF withholding, employee social security, the taxable payroll base, and the resulting annual net salary using an official-flow common-regime Spain model.
For common-regime Spain, the page follows the official AEAT 2026 retention structure together with current employee social security rules. Basque Country and Navarre still need separate foral tools, and live employer regularization can still create final payslip differences.
No within the supported scope here. The calculator is built for common-regime Spain only, so the same official AEAT withholding flow applies throughout that scope.
The page switches from the usual common-regime IRPF model to a special displaced-worker estimate based on the AEAT flat-rate structure. Use it only if your case really qualifies for that regime.
It is the common nickname for Spain’s special tax regime for qualifying workers displaced to Spain. Instead of the standard common-regime IRPF route, eligible workers can be taxed under a special structure for a limited period after moving.
The main attraction is predictability. Eligible workers can sometimes compare relocation offers more clearly because the employment-income tax treatment is flatter than the usual progressive route.
No. Those territories use foral tax systems, so the result is not presented as a final withholding estimate there.
Because IRPF withholding is personal. Family circumstances can change the official-flow estimate shown here.
Contract type mainly changes the worker unemployment contribution, which in turn changes the payroll base that the tax estimate starts from.
Yes. Switch the page to target net mode, choose the pay period you care about, and the calculator will solve back to a likely gross annual salary before estimating the withholding effect.
