Renting a Home or a Business Premises: Why VAT Changes Everything

Renting out a property isn’t always the same from a tax standpoint, even when the contracts look alike. The one factor that changes everything is what the property is used for: whether it’s leased as a primary residence, or as a business premises, office, or any other commercial use. That distinction determines whether VAT applies, whether income tax needs to be withheld, and which forms have to be filed. Mixing up the two regimes is one of the most common mistakes small landlords and self-employed owners make when they start renting out property from their own portfolio.

Residential leases are (almost always) VAT-exempt

Spain’s VAT law exempts the leasing of buildings, or parts of buildings, used exclusively as housing. In practice, if you rent a flat to an individual who will live in it, you don’t charge VAT on the rent: the tenant pays the amount agreed, with no 21% added on top. There’s no special request to file or notification to send to the tax authorities — the exemption applies automatically by law.

There are nuances worth watching, though. If the same contract includes a parking space or storage unit attached to the flat, the exemption usually covers those too. But if the tenant is a company subletting the flat to its own employees, or if the property is used for short-term or holiday rentals with hotel-style services (daily cleaning, linen changes, reception), the exemption may not apply, and the letting could instead be taxed as a hospitality activity, with VAT charged at the corresponding rate. The general rule is simple: a primary residence let to an individual is exempt; any other use or intermediary arrangement needs to be reviewed case by case.

Renting an office or commercial premises: here VAT applies, and usually withholding too

When a property is leased for business or professional use — an office, a retail unit, a warehouse — the exemption doesn’t apply. The landlord must charge VAT on every rental invoice, at the standard rate. If, say, the agreed monthly rent is €1,000, the invoice must include VAT on top of that amount, which the tenant pays alongside the rent and the landlord remits to the tax authorities in their quarterly VAT return (Modelo 303).

On top of VAT, leases of business premises typically carry a personal income tax withholding as well. If the tenant is a company or a self-employed professional keeping business accounts, they must withhold a percentage of the rent, declare it quarterly on Modelo 115, and pay it directly to the tax authorities. The landlord never receives that withheld amount — the tenant withholds and pays it, and the landlord later recovers it as a tax credit on their own income tax or corporate tax return. As a result, landlords typically receive the net rent minus that withholding, even though the invoice shows the full amount plus VAT. It’s worth checking every year, once Modelo 115 has been filed, that the amounts withheld match what was actually invoiced — mismatches are common when the tenant changes or the rent is revised partway through the year.

Waiving the exemption: when it makes sense and what it requires

There’s a middle-ground scenario that causes a lot of confusion: a landlord wants to charge VAT even though the use would, in principle, be exempt — for example, leasing to businesses for activities that are subject to and not exempt from VAT, where being able to deduct the VAT paid on purchasing or renovating the property makes it worthwhile. For pure residential leases, waiving the exemption isn’t an option — the law simply doesn’t provide for it in this case. Where waiving an exemption does come into play is in the sale or transfer of property and other exempt transactions under Article 20 of the VAT law, provided the buyer or tenant is a VAT-registered party entitled to full or partial deduction of the tax. Before waiving any exemption, the specific case needs a close look, since the decision is irreversible and comes with strict formal requirements (an explicit, prior notification, and the right status for the other party) — if these aren’t met, the waiver is invalid and the transaction remains exempt regardless.

At Zythos Business, we guide self-employed professionals and SMEs through exactly this kind of decision, where a simple difference in how a property is used can completely change the invoice, the withholding, and the quarterly filing obligations. We review every lease before any invoice goes out, work out the VAT and 115 withholding correctly, and make sure everything ties out on the relevant forms — so our clients can rent with the peace of mind that the tax side is sorted from the very first payment.
