In this article we explain when you pay land sales tax, how to calculate it, how to avoid it and what to look out for if you are a business. And we won’t forget a practical step that sellers often forget – opting out of property tax.
What is land sales tax
Land sales tax is an income tax that is paid on the earnings (profit) from the sale of land. However, it is not always paid. In some cases, you may be exempt from land sales tax.
Who pays land sales tax
Income tax on the sale of land is payable by the seller unless they meet the conditions for exemption. Taxable income arises if the difference between the sale price and the purchase price is positive, i.e. if the seller has made a profit on the sale.
Who does not pay tax on the sale of land
The Income Tax Act provides for several situations in which income from the sale of land is exempt from tax. Exemption is available in two cases:
Meeting the temporal test of possession
The most common reason for exemption is a sufficiently long period of ownership of the land. If you have owned the land:
- at least 10 years if acquired after 1 January 2021, or
- at least 5 years if acquired before 31 December 2020,
the income from its sale is fully exempt.
The time test starts from the time you acquired the land and runs until the date of sale. If the land is transferred during this time (for example, by gift), the time test starts again.

Use the proceeds of the sale for your own housing
Even if you don’t meet the time test, you may be exempt from tax if you use the proceeds of the sale to provide for your own housing needs. This includes, for example:
- buying a flat, house or building plot,
- the construction or renovation of a residential property,
- repaying a loan used for your own home.
If you use the whole amount, the income is fully exempt. If only part of it, only the corresponding part of the income is exempt.
Housing expenses can be claimed up to one year after the sale, or back for the previous year if incurred before the sale.
Previously, this had to be notified to the tax office, but from 1 July 2024 the notification obligation no longer applies. However, you must be prepared to prove that the money was actually used for the purpose of your own home (e.g. purchase contract, invoice, loan agreement).
For apartments and houses, there is a third option for sales tax exemption. This states that you are exempt if you have lived in the property for at least two years. However, this option is not available for land because the land itself does not fulfill the purpose of a permanent residence.
How to pay tax on the sale of land – income tax
If you don’t meet the conditions for exemption when you sell the land (for example, you don’t meet the time test or use the money for your own home), you must pay income tax on the sale. However, only the profit is taxable, not the entire sale price.
What is taxed and how is the gain calculated?
The basis for calculating tax is the profit on the sale of the land, i.e. the amount you actually earned. This profit is calculated by deducting the purchase price of the land from the sale price, as well as any other deductible expenses related to the sale or improvement of the land. These costs may include, for example, a commission to a real estate agent, the cost of legal services, an expert’s report or technical evaluation of the land. The resulting amount is then the basis for calculating income tax. If these expenses together exceed the sale price, no profit has been made – and no tax is payable.
How much is paid?
The profit is taxed as ordinary income under the Income Tax Act:
- The basic tax rate is 15%.
- If your total annual income exceeds the threshold of 36 times your average monthly income (in 2025 this threshold is CZK 1,676,052 ), the part above this threshold is taxed at the higher rate of 23%.
When and how to pay the tax?
The obligation to pay the tax is dealt with in the tax return for the year in which the sale took place. The income from the sale is reported under other income.
Deadlines for filing the 2025 tax return:
- by April 1, 2025, if you are filing a paper return,
- by 2 May 2025 if you file electronically (e.g., via a data mailbox),
- by 1 July 2025 if your tax adviser prepares the return for you.
The tax is payable within the same period as the return is filed.
Sale of land owned by an entrepreneur or company
No tax exemption applies when the land is classified as business property, i.e. it is registered in the books or tax records of the entrepreneur and is used for business purposes. This means that income tax is always payable, regardless of the length of ownership or the purpose of the use of the money received.
In this case, the income from the sale of the land is considered self-employment income (not other income). This has several implications:
- The gain from the sale is taxed as ordinary business income.
- No exemption can be claimed on the basis of the time test or the use of the funds for one’s own home.
- The difference between income and expenses is subject not only to income tax but also to social security and health insurance.
Property tax exemption
If you sell the property, it is your responsibility to opt out of property tax. The tax office does not automatically know about the change of ownership and the notification must always be made by the former owner.
You must opt out if you no longer own any other property in the tax office’s jurisdiction after the sale. This applies not only to a sale, but also to a donation or exchange. The decisive factor is that the transfer of ownership took place in the previous year – i.e. that the application for entry into the Land Registry was submitted by 31 December.
You must submit the notification of the loss of ownership by 31 January of the following year. If you do not do so, the tax office will continue to assess you even though you no longer own the property. Although you are unlikely to be fined, you need to rectify the situation as soon as possible.
There are two ways to opt out:
- electronically via the My Tax Portal,
- in writing by registered letter to the relevant tax office (where the property is located, not where you live).
In both cases, you must provide your details, the exact designation of the property and the reason for deregistration (e.g. sale, donation).
If you own other properties in the region, you cannot opt out completely. In this case, you will file an updated tax return where you will indicate the change – a so-called partial deregistration. You can indicate the change on either your regular or partial return, also by 31 January.
Summary
When land is sold, income tax is payable on the gain, i.e. the difference between the sale price and the purchase price. You don’t pay tax if you own the land for at least 10 years (or 5 years if acquired by the end of 2020) or if you use the proceeds of the sale for your own home.
The basic tax rate is 15%, 23% above an annual income of CZK 1.68 million. The income is declared in the tax return for the year of sale. In the case of entrepreneurs, land in commercial property is always taxed, including social security and health insurance contributions.
After the sale, be sure to opt out of property tax – by 31 January of the following year.
