Not legal or tax advice

Please read before using Casita.tax.

This document was last reviewed by our legal team on 22 June 2026. If you have questions, contact hello@casita.tax.

Software, not advice

Casita.tax is software that prepares a Modelo 210 file from the data you provide. It is not legal advice, not tax advice, and not a substitute for a qualified Spanish gestor or asesor fiscal.

You are the filer

Casita.tax does not act as your fiscal representative. You submit the file to AEAT yourself and remain legally responsible for the contents of your submission.

Estimates only

The figures we calculate are estimates based on the data you entered and the rates published by AEAT. They are not a guarantee of the final tax owed. AEAT may apply additional surcharges, interest, or adjustments at their discretion.

Edge cases

Casita.tax is designed for the common non-resident IRNR scenario (Modelo 210, type 02 imputed income, or rental). If your situation involves complex ownership structures, trusts, mid-year sale events before 2018, or non-EU/EEA residents with rental income, please consult a qualified gestor before filing.
