There have been a lot of lively discussions about buying property in the forums lately! But looking at just the price and location isn’t enough. Today, I want to talk about a topic that might be a bit of a buzzkill but is incredibly important: fines! A friend of mine was hit with a hefty fine for overlooking a small detail, and it was a truly painful lesson. So, I’ve compiled a list of common pitfalls related to fines to help those who are currently house-hunting or have already bought a home.

Tax-Related Fines: Pay on Time or Pay the Price
This is definitely a major source of fines. Spanish taxes are no joke. Buying a property involves several different taxes, and if you miss the payment deadlines, the penalties and late fees will be a painful blow to your wallet.
ITP : This is the main tax on resale properties. It generally must be paid within 30 working days of signing the Escritura (deed of sale). What happens if you’re late? Fines! The penalty is typically 5%, 10%, or 20% of the tax amount, and it increases the longer you delay.
Plusvalía Municipal : This tax is paid to the local town hall and also has a 30-working-day payment deadline. Late payment penalties are similar to those for ITP, increasing proportionally.
IBI : Commonly known as property tax. Although this is paid annually, as the new owner, you are obligated to ensure the current year’s IBI has been paid off. If the previous owner didn’t pay, the town hall will come after you—a common pitfall that can lead to fines for buying property in Spain.
To make it clearer, here is a simple table:
| Tax Type | Payment Deadline | Consequences for Late Payment |
| ITP | 30 working days after signing the deed | Penalty + late fees, typically starting from 5%-20% |
| Plusvalía Municipal | 30 working days after signing the deed | Penalty + late fees, similar to ITP |
| IBI | By the date set by the town hall | Tax arrears record, late fees |
Renovations and Construction: Don’t Try to Do It “Quietly”
After buying a house, it’s natural to want to do some work and renovate it to your liking. But be careful! In Spain, you can’t just start any renovation project. Whether you want to alter a wall, change the plumbing, or even just install an air conditioning unit on an exterior wall, you will likely need to apply for a Licencia de Obra (Building Permit) from the town hall.
If you start work without a permit and are reported by a neighbor or discovered by a municipal inspector, you’ll face a fine. The amount usually depends on the ‘severity’ and cost of the work, ranging from a few hundred to tens of thousands of euros. Don’t even think about getting away with it; neighbors here have sharp eyes. Especially for an obra mayor (major work) like altering a load-bearing wall, the fine can be astronomical, and you’ll also be ordered to restore the property to its original state. That’s a classic case of suffering a double loss.
Renting and Occupancy: The Cost of Missing Paperwork
Besides living in the property yourself, many people consider renting it out. There are pitfalls here too. First is the Cédula de Habitabilidad (Certificate of Occupancy). This document proves your property meets habitability standards. Without it, you theoretically cannot live in it or legally rent it out. Although not all autonomous communities require it, it’s best to check. Even more serious is the issue of tourist short-term rentals. If you plan to list your property on Airbnb for short-term lets, you must obtain a Licencia Turística (Tourist License). The government has been cracking down hard on this in recent years, especially in tourist hubs like Barcelona and Madrid. If you’re caught operating without a license, the fines start in the tens of thousands of euros. The fines are terrifyingly high, so absolutely do not cross this red line
