What is the deadline for paying inheritance tax in Catalonia?

Question

José Manuel Alburquerque · Accepted Answer

Six months from the date of death, both to file the tax return and to pay the tax. The time limit does not wait for the will to be opened or for the inheritance deed to be signed. If more time is needed, a further six-month extension can be requested within the first five months, with interest payable for the extra time. When the time limit starts and ends If the deceased lived in Catalonia and died on 15 March, the tax must be filed with and paid to the “Agència Tributària de Catalunya”, the Catalan tax authority, by 15 September at the latest. If that day is a Saturday, Sunday or public holiday, the time limit ends on the next working day. It must be filed even if there is nothing to pay. And the time limit runs even if the heirs have not yet reached an agreement. Nor does it stop while the notary is processing a handwritten will, as the “Tribunal Supremo”, Spain's Supreme Court, confirmed in 2026. Only a lawsuit over the estate brought within those six months makes the time limit start again once the judgment becomes final. The same six-month time limit applies to the “plusvalía municipal”, the municipal capital gains tax on inherited urban property such as flats, houses, commercial premises or building plots. It is filed with the town hall and can be extended to up to one year if requested in time. The extension If there is not enough time to gather the paperwork or value the assets, an extension of a further six months can be requested, bringing the total time limit to one year from the death. These are the conditions: It must be requested within the first five months. It can be requested by any of the heirs or legatees, the beneficiary of a life insurance policy, the executor or whoever is administering the estate. It covers everyone named in the application. The application states who inherits, what assets there are with their approximate value and why more time is needed. The death certificate is attached. If the tax authority does not reply within a month, the extension is deemed to have been granted. If the tax is paid during the extension, late-payment interest is added from the end of the first six months. If the return is filed late If the return is filed late without the tax authority having demanded it first, a surcharge is payable: 1 % plus a further 1 % for each full month of delay. After one year, 15 % plus the interest accruing from then on. The surcharge is reduced by 25 % if the tax is paid when the return is filed and the surcharge is paid within the time allowed for doing so. If it is the tax authority that detects the delay and demands payment, there is no longer a surcharge, but interest is payable and a penalty may be imposed, which usually costs considerably more. That is why, if a document is still missing after four months, it is advisable to request the extension straight away. And if what is missing is money, the bank can pay the tax out of the balance of the deceased's accounts. The tax authority can also be asked, before the time limit expires, to defer the payment or allow it to be paid in instalments.
