Last year, doing my tax return with my dad at the kitchen table (yes, we still do it together, don't judge), I noticed he had a "primary residence deduction" box that didn't even show up as an option for me. I asked why he got it and I didn't, assuming it was some software glitch. It wasn't. And the actual explanation is more interesting than it sounds.
The deduction that basically doesn't exist anymore
Until December 31, 2012, buying your primary home in Spain entitled you to deduct a percentage of whatever you paid toward it each year (mortgage payments, or the purchase price if you paid cash) on your annual tax return. It was a solid deduction: up to 15% of what you paid, capped at a €9,040 annual base, so up to €1,356 less in taxes per year, per person.
On January 1, 2013, this deduction was eliminated for new purchases. Full stop. If you buy your first home today, this deduction simply doesn't exist for you, no matter how much your neighbor, older sibling or dad still benefits from it.
So why does my dad still get it?
Because of what's called the transitional regime. If you bought your primary residence (or started paying for its construction, or for renovation work) before January 1, 2013, and had already claimed the deduction on some tax return before that date, you keep the right to keep claiming it year after year, even though the deduction no longer exists for anyone new.
It's basically a grandfather clause: the tax authority won't take away something you already had a right to, but it's also not letting anyone new in.
The requirements to keep the right (small print that actually matters)
Buying before 2013 alone isn't enough. Generally you need:
- To have acquired the home (or paid for its construction, or renovation work) before January 1, 2013.
- To have claimed the deduction on some tax return before 2013 (or to have been entitled to claim it, even if you didn't for some reason).
- The home to still be your primary residence (with the usual exceptions: job relocation, marriage, etc.).
If you bought before 2013 but never actually claimed the deduction on any return from those years, you generally lose the right to claim it now, even if the purchase date fits. That's a detail a lot of people miss.
How much you actually get deducted
The percentage splits into two brackets that add together:
- State bracket: 7.5% of what you paid that year.
- Regional bracket: another 7.5% (can vary slightly by autonomous community).
Total: up to 15% of what you paid, with a maximum base of €9,040 a year. If you're married and file jointly while sharing the home, that maximum base is shared between both of you; if you file separately, each of you can apply your own base up to the cap — which sometimes makes filing separately the better move.
Why this doesn't apply if you're buying now
If you didn't own a home before 2013, this deduction isn't available to you whenever you buy — not in 2020, not in 2026, not in the future, unless the government decides to reintroduce it (something that's been discussed but hasn't happened). It's not that "your turn will come eventually": that regime simply doesn't exist for anyone buying from that date onward.
What do exist are other, different deductions depending on your autonomous community (for young buyers, for subsidized housing, for energy efficiency) that have nothing to do with this transitional state deduction. Worth checking what's available where you live, because it varies a lot.
My advice if you land in a gray area (inheritance, marriage, etc.)
If you inherit a home your parents bought before 2013, or marry someone who already had that right, things get more complicated and depend heavily on the specifics: whether you keep ownership, whether it's still their primary residence, whether there's a change of owner. In these cases, it's worth checking with a tax advisor before assuming anything — getting it wrong with the tax authority isn't a great plan.

And if you're considering buying your first home now, the mortgage calculator helps you see the real cost without counting on a deduction that, for most people buying today, simply doesn't exist anymore.
