Most relocation advisors still pitch Andalucía as wealth-tax-free. They are half right. Andalusia gives 100% relief on wealth tax (Article 25 bis of Ley 5/2021). While the state Temporary Solidarity Tax on Large Fortunes (ITSGF) is in force, that relief is limited to the difference between the two bills, so above the threshold the taxpayer pays what the solidarity tax would charge. Reading "100%" on the regional paperwork and assuming the bill is zero is the mistake.
Spain operates two parallel wealth taxes in 2026:
1. Impuesto sobre el Patrimonio (IP) — the wealth tax regulated by Ley 19/1991 and ceded to the autonomous communities. Andalusia's relief on it is the 100% of Article 25 bis of Ley 5/2021; the fifth transitional provision of the same law, in effect since 30 December 2023, replaces that relief, for as long as the solidarity tax exists, with one equal to the difference between the wealth-tax bill and the solidarity-tax bill.
2. Impuesto Temporal de Solidaridad de las Grandes Fortunas (ITSGF, "Solidaridad") — a state tax created by Ley 38/2022 of 27 December 2022, first charged for 2022 and extended by Real Decreto-ley 8/2023 until wealth taxation is reviewed. Nothing is due while net wealth after the €700,000 allowance stays within €3,000,000; above that the scale is 1.7% to €5,347,998.03, 2.1% to €10,695,996.06 and 3.5% beyond (Article 3 of Ley 38/2022).
Net result for an Andalusian resident: nothing below the threshold, the solidarity scale above it. On €5,000,000 of net Spanish assets with no debt: €5,000,000 − €700,000 = €4,300,000; the first €3,000,000 at 0% and the next €1,300,000 at 1.7% — €22,100 a year. Non-residents have the same €700,000 allowance and are assessed on their Spanish assets only (Article 28.Tres of Ley 19/1991).
The layering is deliberate. The state designed the solidarity tax to reach the wealth that regions had relieved; Andalusia answered by limiting its own relief to the difference between the two bills. For the taxpayer the result is one figure — what the solidarity scale charges — which is why a plan built on "Andalusia charges nothing" fails above the threshold.
