It depends. You pay Spanish income tax (IRPF, the tax on your personal income) when you end co-ownership only if you give up your share of the property and the value given to the property today is higher than the value at which it was acquired. Usually you are paid for that share. If you are not, you can still have a gain, and I explain how below. If the historical value is kept, the income tax is zero, with some caution I come back to in the questions at the end.
This article is written for people who co-own property in Spain and live here, British and other expats included. If you are a non-resident, you are taxed differently, and I cover that in my guide to tax when splitting a co-owned property as a non-resident.
Capital gains tax on a co-ownership dissolution is an important piece of the puzzle, but not the only one. You also need to look at the declared value, the compensation, AJD (stamp duty on the deed), municipal land value tax (plusvalía municipal), the risk of TPO (transfer tax) and how everything is recorded at the notary. My main guide to dissolving co-ownership in Spain covers the whole process. Here I stay on income tax.
Why is there usually no income tax when co-ownership is dissolved?
The Spanish term is extinción de condominio, the legal way to end co-ownership of a property held in undivided shares (proindiviso). Three ideas explain almost everything about its income tax treatment:
- A dissolution does not change anyone’s wealth. It turns the undivided share each co-owner already had into specific property.
- If nobody’s wealth changes, there is no capital gain and no capital loss.
- For that to hold, what each person takes home must match their share. If somebody is awarded more than their share (an exceso de adjudicación, or excess of award), the others have a gain or a loss for income tax purposes.
So the question is never whether the dissolution as a whole is taxed. The question is whether anyone has ended up with more or less than their share, and whether the property is worth more today than when it was acquired.
The two examples behind the figures
I use the same two examples throughout. Paco and Pepa bought a flat 50/50 for €100,000. A flat cannot be physically split, so it is an indivisible asset. Carlos and Carla inherited a chalet 50/50 valued at €500,000, and they have divided it into two separate properties after a segregation, so it is a divisible asset. To keep the numbers simple, I leave out acquisition and transfer costs.
When do you pay capital gains tax on a co-ownership dissolution in Spain?
Here are the nine cases side by side. They rest on a ruling of the central tax tribunal (TEAC) and a recent decision of the regional tribunal in Catalonia (TEAR).
| Case | Property | Value today | Shares respected? | Compensation? | Income tax result | Example |
|---|---|---|---|---|---|---|
| 1 | Divisible | Same as acquisition value | Yes | No | No income tax | Carlos and Carla: chalet worth €500,000 today, same as before. Each takes a plot worth €250,000. Gain: €0. |
| 2 | Indivisible | Same | No | Yes, paid in money | No income tax | Paco keeps the flat (€100,000 today) and pays Pepa €50,000. Pepa’s transfer value equals her acquisition value (€50,000). Gain: €0. |
| 3 | Divisible | Same | No | No (no-consideration transfer) | No income tax | Chalet worth €500,000 split into Lot 1 (€300,000) and Lot 2 (€200,000). Carlos takes Lot 1, Carla takes Lot 2, nothing is paid. No increase in value, so Carla’s no-consideration gain is €0. |
| 4 | Divisible | Same | No | Yes, €50,000 for the difference | No income tax | As case 3, but Carlos pays Carla €50,000 for the difference. No increase in value, so the gain on a paid transfer is €0. |
| 5 | Divisible | Higher | Yes | No | No income tax | Chalet inherited at €500,000, worth €900,000 today. Each takes €450,000. There is no excess, so the gain is deferred until a future sale. |
| 6 | Indivisible | Higher | No | Yes, paid in money | Income tax due (the most common case) | Flat bought for €100,000, worth €200,000 today. Paco keeps it and pays Pepa €100,000. Pepa: transfer value €100,000 minus acquisition value €50,000 = gain of €50,000. |
| 7 | Divisible | Higher | No | No (no-consideration transfer) | Income tax due | Chalet acquired for €500,000, worth €900,000 today. Lot 1 (€600,000) goes to Carlos, Lot 2 (€300,000) to Carla, nothing paid. Carla gives up €150,000 of value for free: no-consideration gain of about €66,667. |
| 8 | Divisible | Higher | No | Yes, €150,000 | Income tax due | As case 7, but Carlos pays Carla €150,000. Gain on a paid transfer of about €66,667. |
| 9 | Indivisible or divisible | Lower | No | With or without | Depends | TEAR Catalonia, 2025: home acquired by inheritance, undivided 1/6 share valued at €62,833. On dissolution the owner receives €42,243, a loss of €20,590 that can be offset in the savings income base. With compensation the loss counts; with no compensation it does not. |

The case you will meet most often
It is case 6: an indivisible flat that is worth more than it cost, one co-owner keeps it and pays the other. Pepa transfers her half for €100,000, which is her transfer value. Her acquisition value was €50,000, so she declares a gain of €50,000 in her income tax return. Paco, who takes the whole flat and pays, has no income tax to pay at that moment.
The case that surprises people
It is case 5. The chalet is now worth €900,000 against the €500,000 at which it was inherited, but each co-owner takes €450,000, exactly their share. There is no excess of award, so there is no tax now. The gain is not wiped out. It is deferred to the day each of them sells.
What is a gain for no-consideration transfer?
In Spanish it is a ganancia lucrativa. It appears when you hand over part of what is yours and nobody pays you for it. The tax rules treat that as a gift: you transfer something for no consideration, and the tax office still compares the value of what you gave away with what it cost you.
Case 7 shows how it works. The chalet cost €500,000 and is worth €900,000. Carla takes a lot worth €300,000 when her share is €450,000, so she gives up €150,000 of value for nothing. That is one sixth of the whole chalet, and the part she gave up cost her about €83,333. The difference, about €66,667, is her gain. She has not received a euro, yet she declares it in her income tax return. If Carlos pays her the €150,000 instead (case 8), the figure is the same, but it is now a gain on a paid transfer.
The rule works in one direction only. If the property is worth less today than when it was acquired, the law does not let you use the loss when nothing was paid.
Who pays the income tax: the owner who leaves or the one who stays?
Only the owner who gives up their share, the one who leaves the co-ownership, pays it. That is true whether they receive compensation in money or in kind, provided the value assigned today is higher than the acquisition value. The owner who stays and takes 100% of the property pays no income tax at that moment. For them there is no change in wealth, only an acquisition. If you are the one paying, my guide to buying out a co-owner in Spain goes through the compensation and its tax.
In short:
- If you are paid for your share, you have a gain or a loss.
- If you take less, or nothing, and are not paid, you will have a gain if the property is worth more today. The possible loss does not count.
Should you check the numbers before going to the notary?
Yes. Excesses of award are what move the income tax, and they are much easier to adjust before the deed than after it. Before you go to the notary, work out each person’s excess of award. If you send me the figures, I can run them for you before you sign.
Frequently asked questions
What if we use the historical value so the gain comes out at zero?
On paper, if the compensation is calculated with the same historical acquisition value, there is no increase and the income tax is €0. Tax people call it a technical tie. For example, you bought for €100,000 and you dissolve using that same €100,000. It carries a risk, though. Article 35 of the Spanish Income Tax Act sets a floor: the amount can never be lower than the normal market value. If the value is kept artificially low and the property is worth more, the tax office can check the values, replace yours with the market value and demand the income tax on the undeclared gain, plus interest.
What acquisition date and value will I have afterwards?
You will have two dates and two values. If you owned 50% through an inheritance ten years ago, that half keeps its original date and value. The other 50%, acquired in the dissolution, takes the date of the deed and, as its value, what was paid as compensation.
Does the reference value affect income tax?
Not directly. The valor de referencia (the Cadastre reference value) is the mandatory base for AJD or TPO, or for inheritance tax. But it does get in the way a little. In principle, the transfer value for the person leaving is the compensation they receive, or the unpaid shortfall in what they are awarded. As a floor, it has to be in proportion to market value when there is compensation, and to the reference value when there is none.
If the property is divisible and we respect the shares, is there income tax?
No. If a large plot or a segregated building is divided while strictly respecting the shares, there is no change in anyone’s wealth, even if it is worth far more today. You keep the original date and value for when you eventually sell.
What if I take less and I am not compensated?
That is an unequal split with no compensation, which the tax rules treat as a transfer for no consideration, like a gift. If the property is worth more today than when you acquired it, you do declare a gain in your income tax return, even though you have not received a euro. If it is worth less, the law does not let you use that loss.
