Modelo 210: prepare the file for your gestor

The Modelo 210 is Spain’s income tax return for non-residents who let a Spanish property. Casitana gathers everything your gestor needs for it into one package: what you earned and spent, the nights let, the property facts and your certificate. It does not calculate the tax: your gestor decides and files.

What Casitana prepares

  1. Step 1

    Open Modelo 210

    In the menu on the left, click Tax Management, then the Modelo 210 tab. It has three parts: Help & Guide, Setup and Dossier.

    Tip: Help & Guide explains the whole process, step by step, in the app.

Set it up once

The facts about you and the property do not change from year to year. Enter them once; each year’s dossier uses them.

  1. Step 2

    Your tax profile

    Under Setup, fill in Your Tax Profile: your full legal name, your NIE (Tax ID), your date and place of birth, and the country where you are resident for tax. Click Save Tax Profile.

  2. Step 3

    The property facts

    Under Property Details, choose the property and enter its cadastral reference, the date you bought it and Your share of this property (%). Click Save Property Details. The cadastral values and the purchase price are in the property’s own settings.

    Tip: You find the cadastral reference and values on your IBI bill, and the purchase date and price in your deed.

  3. Step 4

    The certificate of tax residence

    Under Certificate of tax residence, choose the Tax year and click Upload certificate. Your own country’s tax authority issues it, and one certificate covers all your Spanish properties for the year.

The dossier for a year

The dossier is built from what you recorded: your income and expenses, and your confirmed bookings.

  1. Step 5

    Choose the property and the year

    Open Dossier and choose the property and the year. Property facts the form asks for come first, with Nights let (Nº de días): the nights of your confirmed bookings in that year.

    Tip: The year in progress can be chosen too, to see where you stand.

  2. Step 6

    Income and costs

    Income recorded and Costs recorded, grouped by category list what you recorded for the property in that year. Click a category to see its lines, and which have a receipt. Anything you marked Exclude from tax report is left out.

  3. Step 7

    Mortgage interest

    Under Mortgage interest for the year, enter the interest you paid that year, from your bank’s annual statement. It is saved as soon as you leave the field. Leave it empty if you have no mortgage.

    What is still missing

    Not in this package lists anything the dossier could not fill in, so you can add it or tell your gestor. A gap never stops you from downloading the package.

Co-owned propertiesIncluded in the Pro plan

For Pro accounts that record property owners.

  1. Step 9

    Every filer is listed

    When a property has property owners, the dossier lists each of them with their share, NIE or NIF, tax residence, address and date and place of birth. You are listed too when you own part of the property yourself. Assign property owners and their shares on the property page: see Property owners.

  2. Step 10

    Amounts stay at 100%

    Every amount in the dossier covers the whole property. Casitana does not split anything by share: the shares are listed so that your gestor can prepare each co-owner's own Modelo 210.

  3. Step 11

    A certificate for each filer

    Each filer needs their own certificate of tax residence. On the dossier, upload a property owner's certificate next to their name; yours stays on the Setup tab. A filer without one is named under what is missing, and the package includes every certificate that is on file.

    Good to know: A property owner's IBAN is never part of the dossier or the package.

Send it to your gestor

  1. Step 12

    Download the package

    Click Download the package. You get one ZIP file with the dossier as a PDF, your receipts, your certificate of tax residence and a short read-me. Send it to your gestor as it is.

    Good to know: What is deductible, and how the rules apply to you, is for your gestor to decide. Casitana does not calculate the tax.
