Czech Republic Crypto Tax 2026

In 2025 the Czech Republic gave long-term crypto holders something close to what its securities investors have long enjoyed: hold for more than three years and the gain comes out exempt. Layer a CZK 100,000 annual value exemption on top, and a patient holder can realise a substantial position with little or no tax — up to a CZK 40 million ceiling on the time-test relief that catches only the very largest disposals. Sell sooner, and the gain is ordinary personal income at 15% or 23%. This guide works through both reliefs, the cap that limits the larger one, and what the new DAC8 reporting means for documenting a time-test claim.

At a glance

• A CZK 100,000 annual value exemption: total crypto income up to that amount per year is exempt.
• A 3-year time test: gains on crypto held more than three years are exempt, but only up to CZK 40 million of income per tax year, with any excess taxable.
• Short-term gains (held under three years, above the value exemption) are personal income, generally 15%, with a 23% higher band.
• Entities are taxed under corporate income tax instead.
• DAC8 reporting starts for 2026; the cross-check focuses on whether short-term gains were declared and whether time-test claims have documented acquisition dates.

The two reliefs

The Czech regime for individuals is built from two stacked reliefs introduced by the 2025 rules:

1. The CZK 100,000 value exemption

Income from the sale of crypto-assets is exempt up to CZK 100,000 per tax year. It is an annual, taxpayer-level value exemption. If total crypto income for the year is at or below CZK 100,000, it is exempt. Above it, the excess proceeds to the taxable analysis (where the time test may still exempt it).

2. The 3-year time test (capped at CZK 40 million)

Gains on crypto-assets held more than 3 years before disposal are exempt from personal income tax — modelled on the long-standing Czech time test for securities. The crypto-specific limit: even after meeting the 3-year holding period, income is exempt only up to CZK 40 million per tax year, with any excess taxable.

The practical effect is a tiered outcome:

Acquisition-date tracking is therefore decisive — the 3-year test is lot-by-lot and date-driven, like Germany's 1-year rule or Luxembourg's 6-month rule but with a high-value cap layered on.

The short-term rate

Crypto held under 3 years and above the CZK 100,000 value exemption is taxed as personal income: generally 15%, with a 23% higher band for high total income. This follows the general Czech personal income tax structure — there is no separate flat crypto rate. Entities are taxed under corporate income tax instead.

DAC8 and the Czech Republic

From 1 January 2026, CASPs report Czech residents' crypto activity, exchanged to the Finanční správa by 30 September 2027 for FY 2026 (the Czech Republic was among the early DAC8 transposers — see DAC8 transposition by country). The cross-check focuses on two things: whether short-term gains above CZK 100,000 were declared, and whether 3-year-test exemption claims have documented acquisition dates that reconcile with CASP-reported history. A holder claiming the time-test exemption needs the acquisition evidence (see DAC8 impact on individuals).

Practical workflow for Czech residents

1. Track acquisition dates per lot — the 3-year test is date-driven.
2. Apply the CZK 100,000 value exemption to total annual crypto income first.
3. Apply the 3-year test to long-held disposals, capped at CZK 40M/year.
4. Tax remaining short-term gains as personal income (15% / 23%).
5. Reconcile against DAC8-reported data, retaining acquisition evidence for time-test claims.

Choosing and configuring a tool for the Czech Republic

Koinly and Divly both support Czech reporting, but the 2025 reliefs are recent enough that tool logic can lag, so check three things before relying on a figure:

• Does it apply both reliefs — the CZK 100,000 value exemption and the 3-year time test? A tool that models only one of them will misstate the result.
• Does it respect the CZK 40 million cap on the time-test exemption? A tool that treats the time test as uncapped will under-tax a very large long-held disposal.
• Does it apply the 15%/23% personal-income banding to short-term gains rather than a flat crypto rate?

Neither tool will decide whether you are taxed as an individual or an entity, or whether your activity amounts to a business.

Where Wag3s fits

Wag3s Folio tracks per-lot acquisition dates and applies the value exemption alongside the capped 3-year time test — the exact Czech mechanics — then reconciles against DAC8-reported activity, retaining the acquisition evidence a time-test claim needs. For Czech entities operating on-chain, Wag3s Ledger provides audit-ready records and multi-chain reconciliation. Folio produces the figures and the documentation; it supports, rather than replaces, a qualified Czech daňový poradce.

Worked example: applying the two Czech reliefs

A Czech resident, Jakub, has the following disposal activity in 2026:

Step 1 — Apply the value exemption. Total gross income from all three disposals: CZK 280,000 + CZK 75,000 + CZK 1,155,000 = CZK 1,510,000. This exceeds CZK 100,000, so the value exemption does not exempt the full income. The income proceeds to the taxable analysis.

Step 2 — Apply the 3-year time test to Lot A. Lot A was held for approximately 59 months — well over 3 years. The gain is CZK 280,000 − CZK 80,000 = CZK 200,000. Under the 3-year time test, this CZK 200,000 gain is exempt — it is below the CZK 40 million cap.

Step 3 — Tax the short-term gains. Lots B and C are held under 3 years.

• Lot B gain: CZK 75,000 − CZK 60,000 = CZK 15,000
• Lot C gain: CZK 1,155,000 − CZK 1,150,000 = CZK 5,000
• Total short-term taxable gain: CZK 20,000

Tax computation. CZK 20,000 × 15% = CZK 3,000. Jakub's total Czech crypto tax for 2026 is CZK 3,000, despite having total proceeds of CZK 1,510,000 — because the largest gain (the long-held BTC) is fully exempt under the 3-year test.

Acquisition date documentation. Jakub must retain documentation of the March 2021 BTC acquisition to substantiate the 3-year-test claim. On a DAC8 cross-check, the Finanční správa may see the 2026 BTC disposal reported by the exchange and ask for confirmation that the exemption is valid. Without the 2021 acquisition record, the exemption cannot be defended.

Jurisdiction-specific rules: the CZK 40 million cap in practice

The CZK 40 million cap on the 3-year time-test exemption is a targeted restriction on large long-held disposals. At current exchange rates, CZK 40 million is approximately €1.6 million (depending on CZK/EUR). For most retail investors this cap is irrelevant — they will never approach CZK 40 million in a single year from crypto disposals. But for investors who accumulated significant crypto early (early Bitcoin or Ethereum buyers now realising substantial gains) and are planning a large disposal, the cap changes the calculation materially.

Example — large disposal above the cap. A Czech resident acquired 5 BTC in 2015 for CZK 20,000 in total. In 2026 she disposes of all 5 BTC for CZK 70 million. The 3-year test is met. But the exemption is capped at CZK 40 million per year. The taxable income is CZK 70 million minus the CZK 40 million cap = CZK 30 million (ignoring cost deductions; in practice the cost is deductible against the taxable portion). At 15% (or 23% on the portion in the higher band), this is a significant tax on what would otherwise be a fully exempt gain. Planning implication: A holder approaching the CZK 40 million threshold may consider spreading large disposals across multiple tax years — sell CZK 40 million in one year and the balance in the next year, so that no single year exceeds the cap. Confirm the multi-year spreading strategy with a Czech daňový poradce, as the mechanics of cost deduction, cost allocation across years, and the interaction with the value exemption are technical.
