The standard file reaches us this way: a young taxpayer, employment contract with a Madrid-headquartered company, primary residence rented at €700–€1,100 per month, taxable income below the regional threshold. They open Renta WEB, download the draft, find it "reasonable" and submit. The refund matches their expectation. Yet, in tax liability, €1,237 of regional deduction that the Madrid Region expressly recognises for that exact situation is missing. The mistake is not in the draft. The mistake is in assuming the draft contains active regional deductions.
Statutory basis
The deduction is set out in Article 8 of the Consolidated Text of Madrid Region tax provisions on State-ceded taxes, approved by Legislative Decree 1/2010 of 21 October, as amended by successive regional fiscal-measures laws. It is a regional deduction operating on the regional tranche of the personal income tax (IRPF) liability — not a State deduction. It applies only to taxpayers tax-resident in the Madrid Region during the relevant year.
Requirements for the 2025 campaign
The deduction requires four conditions to be met simultaneously. Failure to meet any one of them removes the entitlement in full, not proportionally:
- Age — under 40 as of 31 December 2025. Anyone turning 40 during the year still qualifies for the entire year, since the cut-off date is the year-end and not each monthly payment.
- Primary residence — the leased property must constitute the taxpayer's habitual residence under the definition of Article 41 bis of the IRPF Regulation (RIRPF). It cannot be a secondary residence, a seasonal rental or a tourist let.
- Taxable income ceiling — the sum of the general taxable base and the savings taxable base may not exceed €25,620 in individual filing or €36,200 in joint filing. The calculation is performed before applying the personal and family minimum, not after.
- Deposit lodged with IVIMA — the landlord must have lodged the deposit with the Madrid Housing Institute (IVIMA) under Article 36 of the Spanish Urban Lease Act (LAU). Without verifiable lodgement, the AEAT can deny the deduction in a subsequent review even if the taxpayer meets the other requirements. Verification is performed via the deposit reference number on the IVIMA online portal.
There is also a negative condition: the taxpayer cannot own or hold usufruct over another dwelling located within 30 km of their workplace. This clause aims to prevent leasing being used as a tax instrument when there is already accessible owned housing.
How much is actually deductible
The deduction is 30% of amounts paid during the year, capped at €1,237 in tax liability. The cap is reached at an annual rent of approximately €4,123 — equivalent to €344 per month. Beyond that, increasing the rent no longer increases the deduction: the cap binds the liability, not the percentage. Three concrete examples:
- Rent €350/month (€4,200 annually) — calculated deduction €1,260, effective relief €1,237 (cap).
- Rent €700/month (€8,400 annually) — calculated deduction €2,520, effective relief €1,237 (cap, with broad headroom).
- Rent €300/month (€3,600 annually) — calculated deduction €1,080, effective relief €1,080 (below the cap).
In joint filing, when both spouses meet the requirements separately, the deduction may reach the joint cap twice over, provided both sign the lease as tenants and demonstrate individually traceable rent payments. The regional administrative doctrine has been restrictive on this point: cohabitation alone is not enough; the lease must reflect the contractual fit.
How to enter it in Renta WEB
Renta WEB does not pull the deduction in automatically. The operational route is: Regional deductions section → Madrid Region → Lease of primary residence. The system requests the total amount paid during the year and the landlord's information. The cap is applied by the tool.
Documentation worth keeping on file before submission — and retained for the four-year limitation period under Article 66 of the General Tax Act (LGT) in case of a subsequent inquiry:
- Lease agreement signed under the LAU.
- Bank evidence of the twelve monthly payments (transfer or direct debit; cash payment is legally valid but produces a weak evidentiary position in case of inquiry).
- Landlord's tax identification number (NIF), required by the AEAT for cross-matching with the landlord's own IRPF return.
- IVIMA deposit reference number.
Adjacent age bands
Taxpayers between 40 and 65 qualify for a reduced version: 20% rate, cap of €840 in liability and taxable income threshold of €24,107 in individual filing. Taxpayers over 65 face additional case-specific conditions worth reviewing individually. When planning the year before a 40th birthday, it often makes sense to sign a new lease while still under 40, as the 30% rate then applies for the entire tax year.
What does not qualify
The deduction does not apply in four situations we see recurrently in campaign queries:
- Subleases — the subtenant is not a party to the principal lease under the LAU and falls outside the regional benefit, even if the rental is for primary residence use.
- Per-room leases — the contract covers part of the property, not the entire dwelling; the deduction requires a lease of the entire primary residence.
- Tourist or seasonal lets — these are governed by regional tourism legislation rather than the LAU and do not qualify.
- Digital platforms without an underlying LAU contract — a lease arranged via Airbnb, Booking or similar platforms operating under tourism rules does not generate the deduction, regardless of effective duration.
Our position
We treat this deduction as one of the recurring checkpoints in every campaign. When a file reaches us, we verify four items before reading the draft: age at year-end, effective residence in Madrid, approximate taxable income and the lease regime. If the four match, we trace the IVIMA deposit before adding the deduction, because we know that is exactly where the AEAT pushes back if the file is selected for review. As a result, we never enter it without confirming the deposit. The recovered tax liability comfortably outweighs the verification time, and the file is shielded against later inquiry.
