About Us
MoneyBackKit Spain is a free set of tools that helps people living or working in Spain understand their pay and rights, and get the money they are owed.
What you can do here
Work out your 2026 net salary with the Tax Agency's own withholding formula, your final pay (finiquito), severance, unemployment benefit, sick pay, the self-employed fee, an invoice with VAT and IRPF, VAT, your mortgage payment and flight delay compensation with a ready letter.
How our tools work
Every tool is free, needs no signup and works on any phone, in Spanish and English. The tools run fully inside your browser, so your details never leave your device. The site is kept free by ads.
How we keep it accurate
We build the tools from official sources such as the AEAT withholding algorithm, the contributions order in the BOE, the Workers' Statute, SEPE guidance and Regulation (EC) No 261/2004, and we show when the rules were last checked. Rules change, so always confirm with the official source before you rely on a result.
MoneyBackKit Spain is not a law firm or a gestoría, and is not affiliated with the Tax Agency, Social Security, SEPE or any airline.
Who runs MoneyBackKit Spain
MoneyBackKit Spain is run by the MoneyBackKit Spain admin, a small independent team that builds free tools people actually need.
