Spain's Deducción por Inversión en Vivienda Habitual — Overview
Spain offered a 15% tax credit (deducción por inversión en vivienda habitual) on the total annual mortgage payment — interest plus principal repayments — up to €9,040 per taxpayer per year. Maximum annual saving: €1,356. This deduction was available from 1999 until abolished for new mortgages on January 1, 2013.
Crucially, the deduction applies to the total payment (cuota hipotecaria), not just interest. In the early years of a mortgage, the interest component is high, so the practical difference is small. For most medium or large mortgages, the annual payment exceeds €9,040 and the saving is the full €1,356.
Who Still Qualifies — Pre-2013 Mortgages
- The mortgage must have been signed before January 1, 2013 to qualify — this is a hard cutoff
- The property must be your vivienda habitual (primary residence — where you actually live year-round)
- You must have been claiming the deduction before the 2013 cutoff (a grandfather clause for existing claimants)
- The cap applies per taxpayer — married couples filing jointly each get their own €9,040 cap
- Investment properties, holiday homes, and second residences do not qualify
Post-2013 Mortgages — No Deduction
If your mortgage was signed on or after January 1, 2013, no deduction is available at the state (IRPF) level. The transition law specifically excluded all new mortgages from 2013 onwards. Some autonomous communities briefly maintained regional deductions, but the majority have also eliminated these.
For post-2013 buyers, there is no comparable tax benefit on mortgage interest at either state or regional level for primary residences.
Frequently Asked Questions
Can I refinance my pre-2013 mortgage and keep the deduction?
Yes — refinancing a pre-2013 mortgage generally preserves the right to the deduction, provided the outstanding capital does not increase and the property remains your vivienda habitual. Consult the AEAT for specifics on your situation.
Where is the deduction declared?
In the IRPF annual return (Renta), in Anexo I — Deducciones por inversión en vivienda. The pre-filled Renta Web from the Agencia Tributaria often includes it automatically if your bank has reported the mortgage interest.
