Tax topics to discuss with professionals
New residents ask: When do I become tax resident? Do I pay tax in two countries? What is a gestor vs a tax lawyer? What are “modelos”? Spanish tax touches wages, self-employment (“autónomo”), rental income, capital gains, crypto, worldwide assets reporting in some cases, and local property taxes. Rules change yearly and by region—Twitter threads from 2022 are already hazardous.
Fiscal residency (Hacienda’s view) is not identical to your immigration card. The 183-day heuristic is famous; it is not the only test. Double taxation treaties (your home country may have one with Spain) can determine who taxes what, but you still need clean filing positions and evidence of days and economic ties.
This guide is orientation only—not personal tax advice. If you own property abroad, receive foreign dividends/pensions, run a limited company overseas, or contemplate the “Beckham Law”/impatriate regimes, you need a professional—not a blog.
