CasitaTax

Use this when a non-resident owner of a home in Spain asks how much Modelo 210 (Spanish non-resident income tax on the property) they owe for a tax year. Works out each owner's tax on the imputed income of the days the home wasn't let and on the rent, as CasitaTax's simulator does, and returns the method, the sources and a link that opens the simulator with the same answers.

Use this when someone asks when a Spanish Modelo 210 (non-resident income tax) is due for a home in Spain: not let, let all year, let part of the year, or sold. Returns each return's filing window, the direct debit's last day, whether the window is open today, what filing late costs, and the sources (Orden HAC/623/2026 changed the windows from tax year 2026).

Use this when someone needs to know about a Spanish town's cadastral values: the year of its last general revaluation, whether that means the 1.1% or the 2% imputed-income rate for a tax year (pass the revised value to estimate_modelo_210), and its urban IBI rate on homes. From the Catastro's statistics and the Ministerio de Hacienda's open data; País Vasco and Navarra aren't covered.
