## Why use Kyros Utils

### Free, no sign-up

Every tool is free, with no limits, no accounts and no watermarks on what you download.

### Your data stays in your browser

Calculations, signatures, quotes and QR codes are generated on your computer or phone. We don't send or store what you type.

### 2026 tax data

VAT, withholding, payroll income tax and social security contributions follow the official 2026 tables from the Spanish Tax Agency and Social Security.

## Frequently asked questions

### Are the tools really free?

Yes. There's no paid version, no sign-up and no usage limit. The site is funded by advertising.

### Do you store the data I type?

No. Everything is calculated in your browser and nothing is sent to a server. Some tools can remember your details, but only on your own device.

### Do they work for all of Spain?

Yes, for the common tax territory. The Basque Country and Navarre have their own income tax, so the net salary calculator isn't exact there.

### How often is the tax data updated?

We review rates and tables every January and whenever the Tax Agency or Social Security publish changes during the year.
