Deductible Expenses Landlords Commonly Miss on Their IRPF Return

The reduction that applies to net rental income (see our reduction guide) only helps as much as your net income calculation is accurate — and net income depends on correctly capturing every deductible expense first. Under-claiming here is one of the quietest ways landlords overpay.

The commonly recognized categories

These are the categories that are broadly understood to be deductible against rental income for resident landlords under Spanish IRPF rules — treat this as a starting checklist to research against the current AEAT guidance for your specific year, not as an exhaustive, guaranteed list:

• Interest and financing costs on loans used to acquire or improve the property.
• IBI (the annual property tax) and other local taxes tied to the property.
• Community fees (comunidad).
• Insurance premiums related to the property.
• Maintenance and repair costs (as distinct from improvements, which are typically treated differently).
• Agency/management fees, if you use a property manager.
• Amortization/depreciation of the property (excluding land value) and of furnishings, following the applicable depreciation rules.
• Bad debt provisions, under specific conditions, for rent that's genuinely gone unpaid.

Why this list is easy to under-use

A few patterns show up repeatedly:

• Financing costs get missed when a landlord thinks of "the mortgage" as one lump payment rather than separating the interest portion (often deductible) from principal repayment (generally not treated as a deductible expense in the same way).
• Amortization gets skipped entirely — it's a non-cash deduction (you didn't write a check for it this year), which makes it easy to forget even though it's a real reduction to taxable income.
• Small recurring costs (minor repairs, a portion of building insurance) get lumped as "not worth tracking" when, added up over a year, they're not trivial.

This is not the same list as "operating expenses"

Worth repeating because it's a genuine source of confusion: the list for calculating your real-world profitability (which should include every actual cash cost, including things like vacancy loss — see our rental expenses guide) is not identical to the list of expenses deductible for IRPF purposes. Some real costs aren't tax-deductible, and some tax-deductible items (depreciation, notably) aren't a cash outflow in the year you claim them. Keep both lists straight rather than assuming one substitutes for the other.

Quick answers

Should I keep records even for small expenses? Yes — the value of small recurring deductions comes precisely from adding them up consistently over a full year, which requires having kept the records in the first place.

Does the depreciation rule change based on property age? Depreciation follows specific rules that are worth confirming for your exact situation rather than assuming a flat percentage — this is one of the areas where getting professional guidance the first year you claim it pays for itself.

Is this list the same for non-resident landlords? No — non-resident landlords are taxed under a different regime with different (and for non-EU/EEA residents, generally no) expense deductions. See our non-resident tax guide.
