Spain's 10% VAT on Holiday Lets and the 31-Day Line

A change in how holiday-let income is taxed can matter more than a change in the nightly rate. Here's how to read the calendar question without guessing.

Last updated: October 5, 2026

Tax treatment for holiday lets doesn't change what you charge for a night. It changes how a stay is counted. When public reporting describes a rate that turns on how long a guest stays, the calendar becomes the first thing to read, not the price list.

Key Takeaways

• Some tax questions are about dates, not amounts. A line that turns on stay length makes the calendar your primary record.
• Short and long stays can look different on paper. The same apartment can fall into different treatment depending on how the booking is shaped.
• The record is where hosts slip. Missing stay lengths and mismatched payouts hide the detail that decides the question.
• Public reporting isn't the rule. Treat any rate or threshold you read about as a prompt to check, not as a settled fact.
• Your accountant sets the answer. Bring dates, lengths and payouts, then ask how your local authority treats each one.

Why the tax line is a calendar question

Most tax questions are about amounts. This one is about dates.

A stay that runs for a short set of nights can be treated one way. A stay that runs longer can be treated another. That's why the same apartment, at the same nightly rate, can land in different places once the length of the booking changes.

Public reporting describes where that line falls and how it has been moving. The exact wording, the rate and any thresholds belong to the local authority, and they can change. Treat a summary as a prompt to check, not as the answer itself.

So the first move isn't to change your price. It's to look at your own calendar and see what mix of stays you actually sell. That mix is what the question is about, and a host who can describe it plainly is already ahead of one who can't.

It also explains why two hosts in the same city can feel differently about the same headline. One sells mostly weekends. The other rents by the month. The same reported line lands on each of them in a different spot, and sometimes on only one of them at all.

That's worth remembering the next time a headline seems to apply to everyone. The first question to ask is always the same one: how long do my guests actually stay?

What a nightly guest and a monthly guest look like on paper

Picture two bookings. One is a weekend. The other runs for a month.

On a rate sheet, they look like the same transaction at different lengths. On a tax return, they can look like different things. The short stay reads as tourist accommodation, and the longer one may fall under a different treatment. Nothing about the nightly rate tells you which is which.

For a host, the practical difference shows up in the record. A weekend needs a date, a length and a payout. A month's stay needs the same three things, plus a clearer note of why the length matters. The booking itself looks ordinary in both cases.

Here's the trap. Both bookings produce the same kind of row in a booking list. Unless someone records the length while it's obvious, the distinction disappears before it ever reaches your accountant. A tidy list can still be a list that answers the wrong question.

The fix isn't more paperwork. It's one extra field, filled in at the same moment for every booking, so the answer is captured while it's still in front of you.

One practice makes the split easy to see. When you write the booking note, lead with the length. It's the fact that decides the treatment, so it's worth putting first. A booking that starts as a weekend and grows into a month needs its note updated when it changes, because a stale length is the same as a missing one.

Where hosts get the paperwork wrong

Three mistakes come up again and again.

The first is counting nights charged rather than nights stayed. A discounted night or a comped night still occupies the calendar. If the question turns on use, that matters.

The second is mixing short and long stays in one total. If treatment depends on length, a single figure hides the split you need.

The third is keeping the booking record and the payout record apart. When the two don't match, a stay becomes hard to explain later, and the fix usually costs more than the note would have.

None of this is complicated, and all of it gets worse with volume. A busy season means more bookings, more payouts and more chances for a length to go unrecorded. The answer is a consistent note, added at the same point in every booking.

There's a fourth habit worth naming, because it disguises itself as care. Some hosts keep a separate file for the bookings they think might matter, and leave the rest in the main list. That split is invisible until someone asks for the whole period, and then it has to be rebuilt by hand. Keep one record, and keep it whole.

A fifth habit is worth naming, because it's the quietest. Renaming files or moving bookings between folders can break the link between a stay and its payout, and the break only surfaces when someone tries to reconcile the period.

What to check with your accountant

This is a tax question, so the last word belongs to your accountant, not to a blog.

Bring three things: your booking list for the period, the payouts you received, and a note of which stays were short and which were long. Then ask how your local authority treats each one, what rate applies where, and what records to keep and for how long. Ask, too, whether the treatment has changed recently, because something described in the press may still be proposed, published or in transition.

Frame the questions before the meeting, so the time goes on your situation rather than on background. Which of your bookings sits closest to the reported line? Which months produce most of your longer stays? What would change if the treatment moved?

Your dashboard can make that conversation shorter. LOCALSBNB's Home view shows occupancy, average daily rate and revenue per available night, so you can talk about the shape of your year instead of guessing at it. When you need one booking, a read-only assistant over your own data can pull the dates, the length and the payout without changing anything. You can see how the numbers sit together at localsbnb.com.

The aim isn't to become your own tax adviser. It's to arrive with the right facts, so the answer you get is about your situation rather than a general summary. That's a better use of professional time, and it makes the advice cheaper to act on.

One more thing to ask: what to do if the treatment changes mid-year. A booking that straddles a rule change needs a clear record more than any other, and knowing how to handle it in advance saves a scramble later.

It also pays to ask what changing the mix would do. If you moved a few short stays into longer ones, the split would shift, and the effect of that shift is worth understanding before you decide anything. Keep the questions open rather than leading. You want to know how the rule reads your bookings, not to hear that a plan will work.

FAQ

Is a holiday let taxed differently depending on how long a guest stays?

In some places, length matters, and public reporting describes a line between shorter and longer stays. The exact rule, rate and any thresholds are set locally and can change, so confirm the position with your accountant and the local authority. Bring your booking list, so the question is about your stays rather than the rule in general.

Does a longer booking always mean less tax?

Not necessarily. A different treatment isn't automatically a better one, and it depends on the rule where you host. Ask what would have to be true for a different treatment to apply, and how you'd know. Treat any summary as a question to ask, not a conclusion to act on.

What records should I keep for short and long stays?

Keep the dates, the length of stay and the payout for each booking, and note which stays were short and which were long. Your accountant can tell you how long to keep them and in what form.

Nothing here replaces a conversation with a professional. What it does is make that conversation sharper, because you arrive knowing which stays you sold and how long each one ran. Keep the note short and consistent, because the value of a record is that it exists when the question arrives. If you'd like your calendar and your booking detail in one place before you talk to your accountant, have a look at localsbnb.com.
