How do I calculate the tax with multiple owners?

Each co-owner calculates and declares their share separately — proportional to the ownership share recorded in the Escritura. Example: a married couple owns a property in Mallorca at 50% each. Cadastral value €150,000, imputation rate 1.1% (under current AEAT rules), both tax-resident in the EU. Calculation per person: €150,000 × 50% = €75,000 pro-rata cadastral value. Tax base: €75,000 × 1.1% = €825. Tax: €825 × 19% = €156.75. Two separate Modelo 210 declarations required. With mixed use, the number doubles: two declarations per owner (one for rental income, one for imputed income) — generally four declarations for two owners. The ownership share can follow any distribution — 50/50, 70/30, three owners at one third each. What matters is the share notarially documented in the Escritura. Fiscaro supports multiple owners in a single wizard pass and generates the required number of declarations automatically.
