**For most owners: each owner's NIE and passport or ID card, the latest IBI receipt and the title deed.** Add the rent and expenses if you rent the home out, or the deeds if you sold it.

## For each owner

- The NIE, the identification number for foreigners in Spain, with a copy of the passport or ID card.
- The address in the country of residence.
- The signed authorisation to file on their behalf, when we ask for it.

## For the home

- **The latest IBI receipt**, the yearly property tax bill: it shows the cadastral value and the referencia catastral.
- **The title deed** (escritura): who owns the home, and in what shares.

## If you rent it out

- The rent received and, if you live in the EU or the EEA, the expenses to deduct. Our free [rental log](https://casitatax.com/en/rental-log/) keeps them as you go.

## If you sold it

- The sale and purchase deeds, and the 3% the buyer withheld (its Modelo 211).
