**No. CasitaTax is a private service, not affiliated with the Agencia Tributaria. And yes, you can file Modelo 210 yourself, for free, on the Agencia Tributaria's website.** Our price covers preparing and filing it for you.

## Filing it yourself

- There is no blank PDF to fill in by hand: you fill in the Agencia Tributaria's online form, then file it online or print it to pay at a Spanish bank.
- To file online, you identify yourself with Cl@ve, a digital certificate, a Spanish electronic ID card or a European eIDAS identity.
- The form is in Spanish; the Agencia Tributaria publishes its instructions in English.

## What we do

We check your situation, calculate the tax for each owner, file once you approve the figures, send you the filed return and its receipt, and remind you every year.

CasitaTax is run by ZAHARD LTD, a company registered in England and Wales. It is not a law firm, an accountant or a tax adviser.
