Taxes on the Sale of Real Estate: What Sellers Need to Know Before Signing the Contract

28.07.2026 | Views: 28

Taxes Are Part of the Sale, Not a Last-Minute Surprise

When selling a property, sellers often focus primarily on the price, the buyer and the sales contract. Taxes are usually considered only shortly before the transaction is completed. This is a mistake. Tax obligations should be understood before the contract is signed, as they can significantly affect the net amount the seller ultimately receives.

Two tax-related questions most commonly arise when selling real estate: real estate transfer tax and personal income tax on capital gains. The obligations are not the same for every seller, so it is advisable to establish which rules apply to the specific case at the beginning of the sales process.

This article is intended as a general informational guide. For a definitive tax assessment of a specific case, sellers should consult the Financial Administration of the Republic of Slovenia (FURS) or a qualified tax adviser.

1. Real Estate Transfer Tax

Real estate transfer tax generally applies to the sale of a property when the transaction is not subject to VAT. According to FURS, real estate transfer tax is assessed at a rate of 2% of the property’s value or the sale value that represents the tax base.

In practice, the sales contract often specifies which party is responsible for paying the tax. However, sellers should ensure that this matter is not left unresolved. The agreement must be clearly defined before the contract is signed.

When selling a property, it is important to establish:

  • who is liable for paying the tax,
  • what the sale value is,
  • when the tax return must be submitted,
  • when the tax must be paid,
  • whether the transaction is subject to real estate transfer tax or another tax regime.

2. Personal Income Tax on Capital Gains

In addition to real estate transfer tax, personal income tax on capital gains may also apply. This is particularly relevant when the seller sells the property for a higher amount than its acquisition value and the conditions for a tax exemption have not yet been met.

The capital gain is not the same as the selling price. It is the difference between the property’s value at the time of acquisition and its value at the time of disposal, taking into account the applicable rules, eligible expenses and any tax relief recognised under the legislation.

FURS states that taxpayers must submit a capital gains tax return following the disposal of real estate within 15 days of the disposal.

3. The Tax Rate Decreases with the Length of Ownership

For personal income tax on capital gains, the length of time the seller has owned the property is an important factor. FURS explains that the tax rate decreases after every completed five-year period of ownership.

This means that the ownership period can significantly affect the seller’s tax liability. A seller who sells a property shortly after purchasing it may be in a very different tax position from someone who has owned the property for several years.

Before selling, the seller should therefore check:

  • the date on which the property was acquired,
  • the planned date of sale,
  • the purchase or acquisition value,
  • investments made in the property,
  • costs associated with the purchase and sale,
  • whether the conditions for a tax exemption are met.

4. Can the Sale of a Primary Residence Be Exempt from Capital Gains Tax?

In certain cases, the seller may be exempt from paying personal income tax on capital gains when selling an apartment or house in which they had their registered permanent residence and actually lived, provided that the conditions set out in the applicable legislation are met.

Because these conditions are specific and important, sellers should not assume that they automatically qualify for an exemption. Before signing the contract, they should verify whether all the necessary conditions have genuinely been fulfilled.

A common mistake is for a seller to think: “This was my home, so I do not have to pay tax.” That fact alone may not be sufficient. The actual circumstances, the relevant period, the registered permanent residence and the way the property was used are all important.

5. What About the Sale of an Inherited Property?

Tax issues relating to inherited properties can be more complex. It is important to determine when and how the property was acquired, its value at the time of acquisition, whether the seller is selling it immediately after inheriting it and whether a capital gain has arisen.

Before selling an inherited apartment or house, the seller should review:

  • the inheritance decision,
  • the property’s value at the time of acquisition,
  • any investments made in the property,
  • the expected selling price,
  • the period between acquisition and sale,
  • the applicable tax obligations.

When dealing with an inherited property, sellers should pay particular attention not only to the gross selling price but also to the actual net proceeds after taxes and other expenses.

6. What Should the Seller Arrange Before Signing the Contract?

Before signing the sales contract, the seller should have a clear understanding of the applicable taxes, required documentation and expected timeline.

It is advisable to check:

  • the Land Register status,
  • ownership details,
  • any mortgages, liens or other encumbrances,
  • the energy performance certificate,
  • the occupancy permit, where applicable,
  • the relevant tax obligations,
  • who will pay the real estate transfer tax,
  • whether a taxable capital gain may arise,
  • the deadlines for submitting tax returns,
  • when the purchase price can be paid to the seller.

Thorough preparation reduces the risk of the sale being delayed or interrupted shortly before completion.

7. Taxes Affect the Seller’s Actual Net Proceeds

Sellers should not focus solely on the agreed selling price. What matters is how much money they will actually retain after the sale has been completed.

The calculation should take into account:

  • any real estate transfer tax,
  • any personal income tax on capital gains,
  • documentation costs,
  • the cost of preparing the property for sale,
  • real estate agency fees,
  • the repayment of any outstanding loan,
  • notarial and other related expenses,
  • eligible and properly documented investments in the property.

Only after all these items have been considered can the seller obtain a realistic financial picture of the transaction.

8. The Most Common Mistakes Sellers Make

The most common tax-related mistakes include:

  • failing to check the tax implications before advertising the property,
  • confusing real estate transfer tax with capital gains tax,
  • assuming that a tax exemption applies without checking the conditions,
  • failing to retain evidence of investments made in the property,
  • being unaware of the deadlines for submitting tax returns,
  • failing to specify clearly in the contract which party will pay each expense,
  • considering only the gross selling price,
  • checking the tax implications only after the contract has been signed.

Real estate transactions involve substantial amounts of money, which means that even a seemingly minor tax mistake can have significant financial consequences.

FAQ

How Much Is the Real Estate Transfer Tax?

According to FURS, real estate transfer tax amounts to 2% of the property’s value or the applicable tax base.

Do I Always Have to Pay Capital Gains Tax When Selling a Property?

When Must the Capital Gains Tax Return Be Submitted?

According to FURS, the tax return must be submitted within 15 days of the disposal of the property.

Can Renovation Costs Reduce the Tax Base?

Certain investments may be taken into account, but they must be supported by appropriate invoices and documentation. It is advisable to check the specific rules before selling the property.

Should I Check the Tax Implications Before or After Signing the Contract?

Before signing the contract. After the contract has been signed, it is often already too late to optimise the agreement and the transaction timeline.

Taxes relating to the sale of real estate should not be addressed only at the end of the transaction. Before signing the contract, the seller should understand which tax obligations may arise, who is responsible for paying them, which deadlines apply and what the actual net proceeds from the sale will be.
