Capital gains tax in Czechia

Czech law imposes no standalone capital gains tax. Instead, gains from the sale of securities, company interests, and real estate are folded into the personal income tax base under Act 586/1992 Sb. (the Income Tax Act) and taxed at the same progressive rates that apply to employment and business income. For most individuals the rate is 15% on annual taxable income up to CZK 1,762,812 (equal to 36 times the average monthly wage as of 2026), rising to 23% on any amount above that threshold. [1][2]

How are gains from selling securities taxed?

Gains from selling publicly traded shares, bonds, and other securities are generally included in the taxpayer's personal income tax base as "other income" under Section 10 of the Income Tax Act. The deductible cost basis equals the documented acquisition price plus any directly related transaction expenses. The net gain is then added to all other income and taxed at 15% or 23% depending on total annual income. Czech brokers do not withhold tax at source on most domestic securities disposals; the taxpayer self-reports through the annual daňove priznaní (income tax return), due 1 April of the following year (extendable to 1 July for electronic filing or 1 October with registered tax-advisor representation). [1][3]

What is the time-test exemption for securities and company shares?

Section 4 of the Income Tax Act provides one of the most significant reliefs available to Czech individual investors: a holding-period exemption that can eliminate tax on gains entirely.

• Securities (shares in joint-stock companies, bonds, investment fund units): exempt if held for more than 3 years before disposal.
• Participations in limited liability companies (s.r.o.) and other interests not represented by a listed security: exempt if held for more than 5 years before disposal.

Where both conditions are met, the gain is fully excluded from the personal income tax base and need not be reported. An important secondary threshold also exists: if aggregate annual gross proceeds from all securities and share disposals remain below CZK 100,000, the income is exempt even where the holding-period test is not met. [1][3][4]

What is the CZK 40 million annual exemption cap introduced in 2025?

With effect from 1 January 2025, the Czech Income Tax Act was amended to cap the total time-test exemption at CZK 40 million per taxpayer per calendar year. [3][4] Where a taxpayer's combined qualifying disposals (securities held 3+ years, s.r.o. interests held 5+ years) exceed that threshold in a single tax year:

• The first CZK 40 million of aggregate gross proceeds remains exempt.
• The excess is brought into the taxable income base on a proportional basis. Deductible acquisition costs are also reduced proportionally so that only the taxable fraction of costs may be claimed.

For example, if a taxpayer sells two qualifying positions for combined proceeds of CZK 60 million, CZK 40 million is exempt and CZK 20 million is taxable. Deductible costs attributable to the taxable portion are calculated as: (20/60) x total acquisition costs.

A transitional rule allows taxpayers to elect the market value as of 31 December 2024 (supported by an expert appraisal for unlisted assets) as the substitute cost basis for assets acquired before 2025. This is particularly relevant for long-held private-company stakes where original cost is a small fraction of current value. [4][5]

From 1 January 2026, the CZK 40 million cap has been abolished for securities and s.r.o. participations that satisfy the time test. The full gain — regardless of size — reverts to being exempt, provided the holding period is met. The CZK 40 million cap continues to apply to crypto-asset disposals and will not be removed for that asset class. [2][6]

What exemptions apply to real estate gains?

Sales of Czech immovable property are treated differently from securities. Two distinct exemptions apply under Sections 4(1)(a) and 4(1)(b) of the Income Tax Act, and neither is subject to a monetary cap: [7][8]

Primary-residence exemption (2-year rule): Gains on the sale of a family house or residential flat are fully exempt where the seller has maintained continuous residence in the property for at least 2 years immediately before the sale. Sellers who do not meet the 2-year residence test may still qualify if they use the sale proceeds to meet their own housing needs (purchase, construction, or major renovation of a replacement residence) within a defined period.

General ownership exemption (10-year rule): For other real estate - investment properties, second homes, commercial units, and land - gains are exempt where the period between acquisition and sale exceeds 10 years. This 10-year threshold was introduced by Act 386/2020 Sb. and applies to properties acquired on or after 1 January 2021. Properties acquired before that date retain the earlier 5-year ownership test. Again, the exemption period can be shortened if the full proceeds are reinvested in the taxpayer's own housing needs.

Inherited property: Where property is inherited from a direct-line relative or spouse, the testator's ownership period counts toward the required holding period, reducing the effective wait for the successor owner.

Where no exemption applies, the taxable gain equals sale proceeds minus documented acquisition cost, improvement expenditure, and selling-related costs. The resulting net gain flows into the personal income base and faces the standard 15%/23% progressive rates. Sellers with exempt gains exceeding CZK 5 million must notify the tax administrator by the income tax return deadline, even though no tax is due. [7]

How are non-residents taxed on Czech capital gains?

Czech tax non-residents are subject to Czech personal income tax only on Czech-source income. Gains from the disposal of Czech-situs real estate constitute Czech-source income under Section 22(1)(d) of the Income Tax Act and are taxed at the same 15%/23% progressive rates as apply to residents. The same time-test exemptions (2-year residence and 10-year ownership for property) are also available to non-residents on the same terms. [1][8]

For non-residents disposing of shares in Czech companies, taxability depends on treaty status. The Czech Republic has approximately 90 double-tax agreements (DTAs) in force, covering all EU member states and most OECD partners. Under Article 13 of the OECD Model (mirrored in most Czech DTAs), gains on shares in companies that are not real-estate-rich are typically taxable only in the investor's country of residence, not in the Czech Republic. However, gains on shares in Czech companies where more than 50% of asset value derives from Czech real estate may be taxable in the Czech Republic even for non-residents, reflecting the Article 13(4) anti-avoidance rule. [1]

For payments to entities resident outside the EU/EEA and without a DTA or Tax Information Exchange Agreement with the Czech Republic, a higher 35% withholding rate applies to certain Czech-source passive income. Investors from treaty countries generally receive relief at source or via refund claim. [1]

For cross-border considerations and treaty relief claims, consult Czech Republic country overview and engage a qualified tax professional familiar with both Czech domestic law and the relevant bilateral treaty.

What records should taxpayers maintain?

Because the time-test exemption depends on demonstrable acquisition dates, Czech taxpayers and investors should retain:

• Brokerage statements or share register extracts confirming acquisition date and price
• Notarised deeds or land registry records for real estate acquisitions
• Expert appraisal reports for unlisted private-company stakes, especially for assets where the 31 December 2024 market-value election is intended
• Receipts for capital improvements to real estate, which increase the deductible cost basis

CRS/DAC2 automatic information exchange means that foreign-broker transaction data increasingly reaches the Czech Financial Administration (Financni sprava) automatically. Taxpayers should cross-check broker-reported figures against personal records before submission to avoid mismatch queries. [1]
