If you are required to file the Wealth Tax for the 2025 financial year and you own shares or other listed securities (bonuses, subordinated debt...), remember that you must declare these assets based on their average trading values during the last quarter of last year.
If you have shares or participations in unlisted companies, the value to declare will be the following:
- If the entity in which you have holdings is audited, you must declare the book value resulting from the last approved balance sheet.
- If it is not audited, you must declare the higher of said theoretical value, the nominal value of the shares, or the result of capitalizing at 20% the average of the profits of the last three financial years (that is, dividing it by 0.20) in the proportion that corresponds to each partner.
In any case, remember that if your individual participation percentage in the company is at least 5% (or 20% if you own it together with other people from your same family group) and you meet certain additional requirements, you can declare these participations as exempt and not have to pay tax on them in your Wealth Tax.
