Property: joint acquisition valueart. 54 bis RGAT€0.00 · under the threshold
Threshold for each block€50,000.00
  • The threshold is measured on the TOTAL balance or value of the asset, not on your share: if you hold 30 % of a €150,000 account, you report a €150,000 account and state the 30 %.
  • The accounts block has two magnitudes and only one has to pass €50,000. An account emptied on 30 December is reported on its fourth-quarter average alone.
  • Property is measured by its ACQUISITION VALUE, not by what it is worth today: a flat bought in 1998 for €40,000 stays out even if it is worth €400,000 now.
  • Everything is converted into euros at the 31 December exchange rate of the year reported, including the acquisition value of a property bought twenty years ago.
  • If you are self-employed and keep accounts under the Commercial Code, individually recorded bank accounts and property fall outside the duty, but securities do NOT: article 42 ter contains no such exception.
  • Securities, insurance and annuities are valued under the Wealth Tax Act rules, not at the price you paid.
  • Crypto assets held abroad do not go on form 720: they have their own form 721, with its own €50,000 threshold.
  • It does not cover the Basque Country or Navarre: the foral authorities regulate their own version of this declaration.

General information, not tax advice. Thresholds and penalties turn on facts only you know; confirm your case with an adviser or with the Spanish tax agency.

Each of the three blocks is measured separately against €50,000.00: they are never added together.
