I recently bought a small apartment in Madrid, thinking I’d rent it out for some extra cash. However, a friend warned me that rental income is taxable, and getting caught by the tax authorities would be a disaster. I immediately did some research and found there’s a lot to it. Today, I’m sharing what I’ve learned to give new landlords a heads-up, and I welcome experienced landlords to add their insights!
How is Rental Income Calculated in Personal Income Tax?
The rent we receive is classified by the Spanish tax system as a “return on real estate capital” (rendimiento del capital inmobiliario). This income must be included in our annual Personal Income Tax (IRPF) return. The good news is that not all rental income is taxed. We can deduct many related expenses, and only the resulting net income is subject to tax.

What Expenses Are Deductible?
This is the key to reducing your tax bill! The tax agency allows us to deduct various expenses incurred to maintain the property for rent from the gross rental income. I’ve compiled a list of common deductible expenses for your reference:
| Expense Type | Description |
| IBI (Property Tax) | The annual property tax, which is fully deductible. |
| Community Fees | Community management fees (gastos de comunidad) are also fully deductible. |
| Repair and Maintenance | Note: This does not include extensions or major renovations, but rather routine maintenance like painting walls, repairing pipes, etc. |
| Home Insurance | Premiums for fire insurance, liability insurance, etc., are all deductible. |
| Waste Collection Fee | Tasa de basuras. |
| Real Estate Agency Fees | If you used an agency to rent out the property. |
| Mortgage Interest | If you have a mortgage, the interest paid is deductible, but the principal repayment is not. |
| Depreciation | This is more technical. Generally, 3% of the property’s construction value can be deducted annually as depreciation. |
Another Major Benefit: The 60% Reduction
In addition to the deductible expenses mentioned in our guide on filing taxes on rental income in Spain, Spain offers a significant tax break for long-term residential leases. When you rent out your property to be used as a tenant’s “primary residence” (vivienda habitual), after calculating the net income, you can apply a further reduction of 60%! This means you ultimately only pay tax on 40% of your net income. However, if your property is used for short-term holiday lets, you are not eligible for this reduction, and all net income is taxable. Therefore, the tax implications between long-term and short-term rentals are vastly different.
Being a landlord in Spain isn’t as daunting as it might seem, as long as you keep clear records and save all your invoices and receipts. Filing your taxes legally allows you to take advantage of numerous tax benefits. Never choose not to declare just to save hassle; if you’re caught, the fines can be staggering. I hope this information has been helpful to everyone!
