Inheritance tax in Catalonia: what you need to know

It is the first question everyone asks and the one that causes most fear. The short answer: Catalan family estates pay considerably less than people expect — but only if you file on time and claim the reliefs.

Where the rules come from

The tax is set by national law but devolved to the autonomous communities, which may set their own reliefs, rates and allowances. Catalonia has used that power extensively.

The result is that the same estate is taxed very differently depending on the region, so establishing which regional rules apply is the first step.

The deadline

Six months from the date of death. It is the single most important fact in this guide.

A further six months can be granted, but the extension must be requested within the first five months. Miss that and no extension is possible.

What reliefs exist

Relief by degree of kinship, an additional relief by age for those over seventy-five, relief for disability, relief for acquiring the deceased’s main home (subject to a holding period), relief for a family business or shareholdings, and relief for life insurance.

None applies automatically: each must be claimed and evidenced in the return.

How it is calculated

Determine the gross estate, add the statutory household goods uplift, deduct allowable debts and the costs of final illness and funeral.

Apply the reliefs to each heir’s share, arrive at the taxable base and apply the progressive rate. The result is adjusted by coefficients for kinship and pre-existing wealth, and the allowance against tax due is then applied to the resulting liability.

Do I have to file even if the tax comes to zero?+

Yes. The obligation to file is independent of whether tax is payable. Not filing also prevents you registering assets and proving title to banks and registries.
