Spain employs a progressive tax system with some of the highest rates in Europe, administered jointly by national and regional authorities. The Basque Country, where San Sebastián is located, operates under a unique foral tax system (fueros) that provides significant autonomy in tax collection and rates. This system typically results in lower effective tax rates compared to the common Spanish tax regime, making San Sebastián particularly attractive for high-income expatriates. The Spanish tax year matches the calendar year (January-December), with filing deadlines typically in June for most taxpayers. For expatriates, Spain offers several beneficial tax regimes that may significantly reduce tax burdens during initial residency years.
