Selling an Inherited Property: Will You Be Taxed?
You have just inherited your parents' house. Since this is a direct-line inheritance, no inheritance tax was paid on the property.
Everyone in the family already has a home, and the decision is therefore to sell the property.
Will you be taxed when the property is sold?
If the property is not your main residence, the answer is generally yes. You may be taxed on the capital gain realised upon sale.
At this stage, it is important to know the date of the last acquisition for consideration. In other words, when did the parents purchase the house?
If the acquisition took place more than five years ago, the transaction will generally fall under the long-term capital gains regime applicable to property sales.
In the opposite case, the speculative gain regime may apply. This regime is generally less favourable because the gain is taxed as ordinary income according to the taxpayer's personal tax situation.
Difference Between Long-Term Capital Gain and Speculative Gain
- Long-term capital gain: this generally applies to properties held for more than five years. It is usually taxed at the half overall rate, with a maximum of 21% excluding the contribution to the Employment Fund.
- Speculative gain: this generally applies to properties resold within a shorter period after acquisition. It is taxed as ordinary income and may reach a maximum rate of 42% excluding the contribution to the Employment Fund.
- Important: temporary measures have existed for certain periods. The rules applicable on the date of sale should always be checked.
The effective tax rate always depends on the taxpayer's personal tax situation and on the legislation applicable at the time of the sale.
Concrete Example of a Capital Gains Calculation After Inheritance
In our example, the parents bought the house in 1982 for a total amount of 60,000 €, including costs.
Over the years, several investments were made in the property:
- Replacement of the window frames in 1990: 10,000 €.
- Replacement of the heating system in 1998: 15,000 €.
- Construction of a veranda in 2020: 30,000 €.
- All invoices have been kept.
These documents are valuable because they can justify certain investments made in the property and may reduce the taxable basis used to calculate the capital gain.
The property is eventually sold for 650,000 €.
The estate agency fees amount to 20,000 €.
How Is the Capital Gain Calculated?
From the sale price of the property, several items may be deducted:
- Estate agency fees.
- Works justified by invoices.
- The acquisition price of the property, including costs.
The various amounts are then revalued using the applicable coefficients for the relevant years.
| Item | Calculation | Amount Taken Into Account |
|---|---|---|
| Sale price | - | 650,000 € |
| Estate agency fees | - | 20,000 € |
| Purchase in 1982 | 60,000 × 2.50 | 150,000 € |
| Window frames in 1990 | 10,000 × 1.94 | 19,400 € |
| Heating system in 1998 | 15,000 × 1.63 | 24,450 € |
| Veranda in 2020 | 30,000 × 1.09 | 32,700 € |
| Calculated capital gain | 403,450 € |
In this example, the calculation is therefore:
650,000 € − 20,000 € − 150,000 € − 19,400 € − 24,450 € − 32,700 € = 403,450 €
Applicable Tax Allowances
In certain situations, several tax allowances may reduce the taxable capital gain.
- 75,000 € for certain direct-line inheritances meeting the legal conditions.
- 50,000 € per taxpayer every ten years, or 100,000 € for a couple taxed jointly.
In our example, the taxpayer is married and benefits from joint taxation.
The total amount of the allowances is therefore:
75,000 € + 50,000 € + 50,000 € = 175,000 €
The taxable capital gain then becomes:
403,450 € − 175,000 € = 228,450 €
What Amount of Tax Could This Represent?
The amount of 228,450 € is not the tax payable. It is the taxable capital gain after deduction of the relevant allowances.
When the property has been held for more than five years, the transaction generally falls under the long-term capital gains regime. For illustration purposes, this regime usually benefits from the half overall rate, with a maximum of 21% excluding the contribution to the Employment Fund.
In our example, if an indicative rate of 21% is applied, the tax could be estimated as follows:
228,450 € × 21% = 47,974.50 €
The contribution to the Employment Fund may still be added to this amount. The actual tax due will always depend on the taxpayer's personal tax situation and on the rules applicable at the time of the sale.
Simplified Comparison of the Two Regimes
| Situation | Tax Principle | Indicative Amount |
|---|---|---|
| Long-term capital gain | Half overall rate, with a maximum of 21% excluding the contribution to the Employment Fund. | 228,450 € × 21% = 47,974.50 €. |
| Speculative gain | Taxed as ordinary income, with a maximum rate of 42% excluding the contribution to the Employment Fund. | 228,450 € × 42% = 95,949 €. |
These amounts are provided for illustration purposes only. They do not include the contribution to the Employment Fund and do not take into account the taxpayer's personal tax situation.
