Are there exemptions for young buyers or first home purchase?

Who can get the exemption?

You must meet these conditions, under the law:

• be 35 or under on the date of purchase;
• not be someone else's dependant for income tax (IRS) in the year of purchase;
• be buying your first home;
• the home must be only your own permanent home, the one you will live in;
• not have owned a home on the date of purchase, or in the three years before.

For a couple, the conditions are checked for each person, in equal shares. Each files their own IMT return.

What are the limits in 2026?

• Up to €330,539: no IMT and no purchase stamp duty.
• €330,539 to €660,982: IMT of 8% only on the part above €330,539.
• Above €660,982: IMT of 6% on the whole value.

On the purchase stamp duty, which is 0.8%, the deduction goes up to €2,644.31. That is the tax on €330,539.

An example with the sums

A young buyer pays €300,000 for the home they will live in. They pay no IMT and no purchase stamp duty. Without the exemption, they would pay €10,542.04 in IMT and €2,400 in stamp duty.

If the home costs €400,000, they pay €5,556.88 in IMT and €555.69 in stamp duty. Without the exemption, it would be €18,236.65 and €3,200. These are example figures.

The 0.6% stamp duty on the loan is still due.

Can I lose the exemption?

Yes. You lose it if, in the next six years, the home is used for something else. There are exceptions: selling the home, family changes such as marriage or children, or moving job more than 100 km away.

You also lose it if, in those six years, you become a dependant for income tax.

What about the State guarantee for young buyers?

If you are 35 or under, you may also get the State guarantee, subject to other conditions. With it, the bank can lend between 85% and 100% of the home's value. The home cannot cost more than €450,000.

The guarantee applies to contracts signed by 31 December 2026. The bank does not have to grant the loan.
