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.
unrented: not let during the tax year (own use, empty); rented: let all year; part: let part of the year.
Where the owners live for tax purposes: eu (a country of the EU, or Iceland, Norway, Liechtenstein), uk (United Kingdom), other (anywhere else). One value for all the owners.
The home's valor catastral in euros, for the tax year: on the IBI receipt (total, not just the land or the building).
For rented or part: the rent received for the whole home during the tax year, in euros, before expenses.
Number of owners, 1 to 6, with equal shares. Default 1.
Whether the town's cadastral values were revised collectively and in force since the year the rules require (town_cadastral_data tells). Default unknown: the tax is then a range.
For rented or part, owners resident in the EU or the EEA: the deductible expenses of the rented period for the whole home, in euros. Ignored for others, who are taxed on the gross rent.
Language of the CasitaTax pages linked in the answer: da, de, en, es, fr, nl, no, fi or sv. Default en.
Tax year (the year the income relates to). Default: the latest year whose rules are final.
For occupancy part: the number of days the home was let during the tax year.
Each owner's share of the home in percent, when the shares differ (e.g. [60, 40]); they add up to 100. Replaces owners.

From the Catastro's statistics and the Ministerio de Hacienda's open data; País Vasco and Navarra aren't covered.
