Czech Real Estate VAT 2026: Tax Risks in Leasing vs Sale

For developers and real estate investors, 2026 is a year in which it is essential to distinguish with the utmost care between the tax implications of sales and leases under Czech law. The statutory rules remain uncompromising, and an incorrect assessment of the differences between VAT-exempt leasing and a taxable sale in the Czech Republic may result in additional tax assessments amounting to millions of Czech crowns. This article will provide you with key answers on how to avoid unnecessary tax risks.

Quick summary

• The 5-year rule (60 months): A real estate sale is subject to VAT if it takes place within 5 years of first use (final approval/occupancy approval). After this period, the sale is generally VAT-exempt (without entitlement to input VAT deduction) under Czech VAT rules.
• The difference between leasing and sale: The lease of residential units for permanent housing is, by law in the Czech Republic, VAT-exempt without entitlement to input VAT deduction. By contrast, a sale within the first 5 years is a taxable supply at the standard rate of 21% (or the reduced rate of 12% for social housing).
• Input VAT adjustment over 10 years: If a developer claimed an input VAT deduction (planning a sale) but later decides to lease the property (as an exempt supply), the originally claimed deduction must be repaid to the state through an annual adjustment of the claimed tax.
• A substantial change restarts the period: Extensive reconstruction (meeting the definition of a substantial change to a building under Czech VAT legislation) may restart the five-year time test. If you sell the property earlier, the sale becomes a taxable supply with all impacts on price and profit.

VAT in development projects: The reality in 2026

While the income tax exemption periods have been extended (from 5 to 10 years), in VAT the key threshold remains 5 years (60 months) in the Czech Republic. The Czech VAT Act, as applicable for 2026, provides that after this period from the first occupancy approval, the supply of immovable property is exempt from tax.

For developers delivering multi-unit projects or combining leasing with sales, correctly determining this moment is crucial. It determines whether you can claim (and keep) input VAT deductions on inputs (construction materials, services, design works), or whether you must repay them to the state.

ARROWS advokátní kancelář attorneys, with a focus on tax obligations in the construction sector in the Czech Republic, will prepare you for these rules and ensure your tax strategy reflects the true nature of your project. We handle complex situations where a single project includes multiple tax regimes at the same time (apartments, commercial premises, social housing), and we can plan and structure them correctly from the outset.

What the 5-year time test and the “first supply” mean

The key to understanding the legislation lies in Section 56 of the Czech VAT Act. A taxable supply is the transfer of immovable property (a building or a unit) carried out within 5 years (60 months) from the issuance of the first occupancy approval decision. The same rule applies to an occupancy approval consent, or, as the case may be, the day on which the first use of the building began.

Any subsequent sale of the same unit after this period is automatically VAT-exempt, which also means that the seller has no entitlement to an input VAT deduction in relation to that sale.

In practice, this means that if a developer obtains occupancy approval for an apartment building on 1 August 2024, the five-year period runs until August 2029. If the developer sells an apartment in 2026, it is a taxable supply at a rate of 21% (or 12% for social housing) and the developer claims a full input VAT deduction on inputs.

If the same apartment were sold only in September 2029, the sale is already VAT-exempt by law in the Czech Republic. In that case, the developer cannot claim an input VAT deduction, or (if it was claimed earlier) must make an adjustment to the deduction and repay part of the VAT. This rule is not merely theoretical—ARROWS advokátní kancelář attorneys address it with developers who have had to deal with mistakes in cash-flow planning and pricing.

Related questions on the 5-year time test

1. Is the period calculated from the date the occupancy approval decision becomes final and binding?
Yes, the 5-year period starts running from the issuance of the first occupancy approval decision (i.e., when it becomes final and binding) or the occupancy approval consent, or from the date of first use of the building—whichever occurs first.

2. Can I choose whether a sale after 5 years will be taxed?
After 5 years, the sale is primarily exempt. However, the taxpayer may decide to apply VAT to the sale of real estate to another VAT payer (voluntary taxation). This is a strategic tool to preserve the entitlement to input VAT deduction for commercial real estate in the Czech Republic. However, for sales of apartments to individuals (non-payers), this option is not available—the sale is always exempt after 5 years.

3. What happens if I am not going to sell the apartment, but want to lease it?
Different rules apply to leasing. Long-term leasing of a residential unit for housing is VAT-exempt without entitlement to input VAT deduction under Czech law. This means you cannot claim an input VAT deduction on the acquisition price and construction costs, and if you have already claimed it, you will be required to repay it (input VAT adjustment).

Lease versus sale: Two completely different tax worlds

The difference between a sale and a lease in the VAT context is fundamental and often underestimated in practice in the Czech Republic. The sale of a unit within the 5-year time test is taxed (21% or 12%), and the developer may claim a full input VAT deduction on all inputs. By contrast, the lease of immovable property intended for housing is VAT-exempt under Section 56a of the Czech VAT Act, without entitlement to input VAT deduction.

If a developer plans to lease part of the apartments (a “build-to-rent” model) and sell part, they must distinguish their inputs from the outset and, where applicable, proceed by reducing the entitlement to input VAT deduction.

Even more common is a situation where a developer builds apartments with the intention to sell (claiming a full input VAT deduction), but due to market conditions decides to lease the apartments temporarily. This changes the purpose of use of the asset. In such a case, an input VAT adjustment applies under Section 78 et seq. of the Czech VAT Act, with a 10-year adjustment period for immovable property.

If a developer completes an apartment in 2025 and starts leasing it for housing in 2026 (an exempt supply), they must repay to the state one tenth of the claimed deduction for each year of leasing within the ten-year period.

An error in this calculation or failure to comply with this obligation leads to additional tax assessments and penalties. ARROWS advokátní kancelář helps clients navigate this labyrinth. We will prepare a detailed plan for how to set up deductions and how to process any changes in the use of the building.

Related questions on leasing versus sale

1. If I lease an apartment for a fixed term and then want to sell it, which regime applies?
During a residential lease, you return a proportional part of VAT (input VAT adjustment under Czech VAT rules). If you then sell the apartment within the 5-year time test from the final approval (occupancy permit), the sale is subject to VAT. You can then “claim back” the remaining part of the deduction through the final input VAT adjustment in the year of sale. If the sale takes place only after 5 years, it is VAT-exempt and you definitively lose the right to deduct.

2. If I lease multiple apartments in one building and want to lease one of them as an office, what rule applies?
Non-residential premises (an office) follow a more flexible regime under Czech VAT legislation. If you lease an office to a VAT payer for their economic activity, you may choose to tax the rent (invoice with 21% VAT). In that case, you retain the right to deduct VAT on construction costs attributable to that space.

Material change to a building and the risk of restarting the time limit

One of the legislative risks is the concept of a material change to a building. Under Section 56(5) of the Czech VAT Act, the five-year exemption period is interrupted and starts running again from the issuance of the final approval (occupancy permit) decision (or consent) for a material change to a completed building.

In practice, this means that if a developer buys an older building that is long outside the time test and carries out an extensive reconstruction (e.g., an additional storey, an extension, or a major overhaul requiring a building permit), this may qualify as a material change.

If the developer then sells the property after such value enhancement, the sale is again treated as a taxable supply (21% or 12% VAT), because a new 5-year test has started. An investor who assumed the sale would be exempt (because “the building is old”) suddenly faces an obligation to pay VAT on the entire sale price.

The Czech Financial Administration (tax authority) assesses a material change primarily based on whether a new final approval decision was issued and whether the value of the works significantly increased the value of the building.

ARROWS advokátní kancelář helps clients prevent these surprises. We will assess whether your planned reconstruction meets the criteria of a material change and prepare a tax strategy for the sale so that your risks are minimized under Czech law.

Adjustment of the right to deduct VAT when combining leasing and sale

For developers implementing multi-unit projects and planning to lease part and sell part, the key issue is the input VAT adjustment under Section 78a of the Czech VAT Act. The monitoring period for real estate is 10 years.

How does it work in practice? Assume a developer builds a house and claims a full VAT deduction (with the intention to sell). However, if the developer decides not to sell certain apartments but to lease them (VAT-exempt), they must adjust the deduction.

Each year the apartment is leased (and therefore used for exempt activity), the developer must return 1/10 of the originally claimed deduction attributable to that apartment.

Example:

• Input VAT for a specific apartment: CZK 500,000.
• The developer leases the apartment for 4 years (VAT-exempt).
• They must return 4 × (1/10 of CZK 500,000) = CZK 200,000 to the state.
• If the apartment is sold after 4 years, the developer may keep the remaining 6/10 of the deduction.

The calculation becomes complex if the regime changes during the year (e.g., part of the year vacant, part of the year leased). This requires precise record-keeping.

VAT rate for social housing buildings: 12%

In 2026, the reduced 12% VAT rate for the construction and supply of social housing buildings continues to apply (following changes introduced by the consolidation package). The condition is that the building meets the statutory definition under Czech law—i.e., an apartment up to 120 m² or a family house up to 350 m².

This rate applies both to the sale itself (if within the 5-year time test) and to construction and installation works related to the construction or reconstruction of such a building. For a project worth CZK 100 million, the difference between 21% and 12% is CZK 9 million, which is a crucial factor in price calculations.

Pay attention to the correct calculation of floor area under Government Regulation No. 366/2013 Coll. (areas under walls are included, but balconies or terraces are not, unless enclosed). An error of just one square metre can mean a jump from the 12% rate to 21%. ARROWS advokátní kancelář recommends having the measurements verified already at the project stage.

Related questions on social housing and the 12% VAT rate

1. If an apartment is 130 m², does the 21% rate apply?
Yes. If the apartment’s floor area exceeds 120 m², the standard 21% VAT rate applies to both the construction and the sale of that specific apartment under Czech VAT rules.

2. What about an apartment building with a mix of apartments?
If an apartment building is constructed where some apartments are up to 120 m² and others exceed 120 m², the social housing regime (12%) applies only to those apartments that meet the limit. Common areas and the building structure are then allocated proportionally, or the character of the building as a whole is assessed (if social housing predominates). A precise calculation is required under Czech legislation.

Correct timing of the sale: How to eliminate the risk of unexpected tax impacts

The five-year exemption period is a critical point. A developer who obtains final approval for a building on 1 August 2024 has two options: either sell within 5 years (taxable supply, the right to deduct remains), or sell after 5 years (VAT-exempt supply, the right to deduct does not apply / must be repaid).

In practice, it happens that a developer “misses” the 5-year deadline and the sale becomes VAT-exempt against their will. This means they cannot claim input VAT (or they must repay a previously claimed deduction for the remaining years of the 10-year adjustment period). This can be financially disadvantageous if construction costs were high.

Conversely, if a developer knows they will be leasing apartments long-term in the Czech Republic, they should assume from the outset that they will not be entitled to a VAT deduction. ARROWS, a Prague-based law firm, can help you prepare a project tax plan focused on the timing of sales and optimising VAT deductions so that you do not incur financial losses due to incorrect timing.

How to avoid the biggest mistakes in 2026

Our Czech legal team at ARROWS, a Prague-based law firm, has identified five of the most common mistakes developers make:

1. Confusing the time tests. The developer confuses the 5-year VAT test with the 10-year income tax test. These are two different taxes with different rules under Czech legislation.
2. Ignoring the deduction adjustment. The developer starts leasing unsold apartments but forgets to make the VAT deduction adjustment in the VAT return (repayment of 1/10 per year).
3. Material change without awareness of the risks. A reconstruction is treated as a “repair”, but for VAT purposes it is a material change that triggers new taxation of the sale.
4. Incorrect definition of social housing. The apartment has 121 m², but the developer applied 12% VAT. The tax authority will assess the 9% difference plus penalties.
5. Not addressing the regime in advance. The developer decides on VAT only at the time of sale, when it is already too late to optimise inputs and contractual relationships.

All of these mistakes can be avoided if the project is prepared with an attorney and a tax adviser already at the preparatory stage.

Practical steps: How to prepare your project for 2026

If you are planning a development project in 2026, we recommend proceeding in the following steps:

Step 1: Use strategy (project phase). Define whether the goal is sale, lease, or a combination. Verify floor areas for social housing.

Step 2: Tax analysis. Have ARROWS, a Prague-based law firm, assess the Czech VAT regime for inputs (full deduction vs. partial deduction).

Step 3: Monitoring deadlines. Carefully record the date of issuance of the first occupancy permit decision (kolaudační rozhodnutí). Set reminders for the approaching end of the 5-year period.

Step 4: Asset records. For each unit, keep records for the purposes of the deduction adjustment (change from sale to lease and vice versa).

Step 5: Regular review. Each year at the end of the tax period, verify whether it is necessary to make a deduction adjustment under the Czech VAT Act.

Conclusion

2026 requires precision from developers. Czech VAT rules relating to the 5-year time test, deduction adjustments, and rates for social housing are strict. Mistakes in tax planning can cost you millions of Czech crowns in repaid VAT and penalties.

FAQ – Most common legal questions on VAT for development projects in 2026

1. From when exactly is the 5-year period for VAT exemption calculated?
The 5-year period (60 months) starts running from the issuance of the first occupancy permit decision (or the date it becomes final) or the occupancy consent, or from the date when the first use of the building commenced—whichever occurs earlier.

2. Is it true that when leasing an apartment I cannot claim VAT on construction costs?
Yes. The lease of immovable property intended for permanent housing in the Czech Republic is VAT-exempt without the right to deduct input VAT. If you claimed a deduction (e.g., during construction with the intention to sell) and subsequently lease the apartment, you must gradually repay the claimed deduction to the state (deduction adjustment over 10 years).

3. What is a material change to a building?
A material change means a superstructure, extension, or building modifications for which an occupancy permit decision/consent was issued and which significantly changed the value or character of the building. In the case of a material change, the 5-year period for taxing the sale starts again from the beginning under Czech VAT rules.

4. What VAT rate applies to social housing in 2026?
For the construction and supply of buildings for social housing (apartments up to 120 m², houses up to 350 m²), the reduced VAT rate of 12% applies.

5. Can I voluntarily charge VAT on the sale of real estate after 5 years have passed?
Yes, but only if the buyer is another VAT payer and the sale is for their economic activity. For sales to individuals (non-payers), VAT cannot be applied after 5 years—the sale is mandatorily VAT-exempt.
