The General Directorate of Taxes clarifies that the exemption for reinvestment in a main residence remains even if the property is classified as an office in the Land Registry. The key is the actual use as a residence.

The General Directorate of Taxes (DGT) has clarified that homeowners selling their main residence will not lose the exemption from income tax on capital gains even if the property is registered in the Land Registry as a professional office. The essential condition is to reinvest the money in the purchase of another home.

The binding consultation V0946-26, recently published, addresses the case of a taxpayer who had been living since February 2023 in a property classified as an office by the Land Registry. The woman asked whether she could apply the reinvestment exemption when selling it. The Tax Authority's response was affirmative: the registration designation is not an obstacle if the general requirements are met.

Article 38 of the Income Tax Law states that the gain obtained from the sale of the main residence is exempt if the total amount is used to purchase another main residence. This tax advantage avoids taxation on the difference between the purchase price and the sale price, provided that the conditions of residence and reinvestment are met.

For a property to be considered a main residence, the regulation requires that the owner has lived in it continuously for at least three years. It is also accepted if it had that status at any time during the two years prior to the sale, even if they no longer live there.

The DGT emphasizes that what matters is the actual use as a residence, not the cadastral classification. This is especially relevant for self-employed individuals who have their home in a property with mixed use or who registered part of it as a professional office. Many feared that this administrative label would cause them to lose the exemption, but the Tax Authority makes it clear that the Land Registry is not a tax judge.

The cadastral registration as an office does not prevent the exemption for reinvestment if you prove that the property is your main residence.

To benefit from the exemption, the taxpayer must reinvest the money obtained in the purchase or renovation of a new main residence. The deadline for doing so is two years before or after the sale. Furthermore, the new home must be occupied within a maximum of 12 months from the acquisition or completion of the works.

If only part of the amount is reinvested, the exemption will be proportional. For example, if sold for 200,000 euros and 150,000 euros are reinvested, only 75% of the gain will be exempt. The remainder will be taxed as capital gains in the income tax return.

An important point for self-employed individuals with an office related to their activity: if they have deducted expenses related to the part of the home used as an office (such as a percentage of property tax, utilities, or depreciation), the gain corresponding to that portion may not be exempt. The exemption only protects the strictly residential part. It is advisable to clearly separate both concepts to avoid problems with the Tax Authority.

The DGT's clarification clears up a common doubt among self-employed individuals and remote workers. It is not enough for the property to appear as a residence for cadastral purposes; it must be demonstrated that one has actually lived there continuously. It is advisable to gather utility contracts, registration documents, previous income tax returns, and any documents that prove that this was the habitual residence.

It is also wise to check if in previous years the deduction for the acquisition of a main residence or the exemption for reinvestment in a prior purchase was applied, as both are linked to the same property. An error in the sequence of operations may attract the attention of the tax inspection.

This clarification has a direct impact on the finances of many self-employed individuals who have avoided selling their homes for fear of losing the exemption. They now know they can do so without worries, as long as the property remains their primary residence. The key is the actual use, not the labeling.

In a context of still high interest rates, the possibility of changing homes without taxing on capital gains is a significant relief. For those with a small business or self-employed, every euro not paid to the Tax Authority is a euro that can be invested in their business. The DGT has made it clear that the Land Registry cannot be an arbitrary brake.

However, total reinvestment remains the cleanest route. If the sale amount is not fully allocated to the new purchase, the Tax Authority will calculate the proportional part of the gain that is taxable. Therefore, before making a decision, it is advisable to crunch the numbers with an advisor and ensure that the reinvestment plan aligns with income and the actual housing need.
