Understanding your Spanish payslip, line by line
A payslip is three blocks: what you earn, what you contribute, and what is withheld. Read in that order, every line falls into place.

TL;DR
A Spanish payslip has three blocks: earnings (base salary, supplements and, where applicable, prorated extra payments), the worker's social security contributions (around 6.5% of gross: common contingencies 4.70%, unemployment 1.55%, training 0.10%, plus the year's MEI) and IRPF withholding, which is personal and adjustable. Net = earnings − contributions − IRPF.
The three blocks of every payslip
Any Spanish payslip, however baroque it looks, is three blocks in a fixed order:
- Earnings (devengos): everything you earn that month.
- Deductions: what you contribute to social security and what is withheld for IRPF.
- Net to receive: block 1 minus block 2.
Read in that order, an intimidating form becomes three subtractions.
Block 1: earnings
The first block adds your base salary, the supplements (seniority, languages, night work, targets…) and, if your agreement prorates them, the prorated extra payments, the two article-31 payments spread across the twelve payslips. Non-salary items (per-diems, expense reimbursements) may also appear and generally do not contribute.
Two payslips with the same gross annual can look very different depending on whether the extras are prorated: to compare jobs, always compare the gross annual.
Block 2a: what you contribute to social security
Your gross carries the worker's percentages, stable for years:
- Common contingencies: 4.70%. Funds healthcare, sick leave and the pension.
- Unemployment: 1.55% on permanent contracts (slightly more on temporary ones).
- Professional training: 0.10%.
- MEI (intergenerational equity mechanism): a small additional contribution whose rate steps up by year; the current one is published by social security.
There is no such split when you work for yourself: an autónomo has no payslip and pays the full 31.50% alone, on a base they choose. That calculation, brackets and all, is in the autónomo contribution calculator.
In total, around 6.5% of gross. The rest of the contribution (the large share) is paid by the employer on top of your salary, which is why it never shows as a deduction.
These apply to the contribution base, which includes supplements and the prorated extras even when you are not paid them prorated. That base matters more than it looks: tomorrow's unemployment benefit, sick pay and pension all flow from it.
Block 2b: IRPF withholding
The second deduction is IRPF withholding: a percentage the company pays to the tax agency on account of your income tax. It is not the final tax; it is an advance that settles in your annual return. It depends on salary, contract type and family situation, and the tool that computes it exactly is the tax agency's withholding calculator.
The practical consequence: a withholding that is too low is not a gift, it is an invoice deferred to June.
The three checks that prevent surprises
- Does the contribution base reflect your real salary? A low base today is a low benefit tomorrow.
- Are the extras prorated or not? It determines how to read your monthly net and how your finiquito will be settled the day the contract ends.
- Does the withholding match your situation? Re-check it in the tax agency's calculator after any change: a raise, a child, a mortgage, a second payer.
This information is educational and is not tax or employment advice. Each year's contribution rates and withholding brackets are published by social security and the tax agency.
Common mistakes
Confusing IRPF withholding with the final tax
Withholding is an advance. The real IRPF settles in the annual return: a low withholding today can be a payment next June.
Comparing net salaries between jobs without checking the payments
A monthly net with prorated extras and one with 14 payments are not directly comparable: compare the gross annual.
Ignoring the contribution base
Unemployment benefit, sick leave and the pension all flow from it. Check it reflects your real salary: a low base today is a low benefit tomorrow.
