From 20 July 2026, the Czech Republic ended the temporary partial diesel excise duty relief. The effective excise duty on diesel increased from CZK 8.011/l to the standard rate of CZK 9.950/l. Fuel station margin regulation also ended on the same date.
Key points
- Until 19 July 2026: the effective diesel excise duty was CZK 8.011/l.
- From 20 July 2026: the standard excise duty rate of CZK 9.950/l applies again.
- Excise duty increase: CZK 1.939 per litre of diesel.
- Including VAT: the theoretical effect on the final price may reach approximately CZK 2.35/l, although the actual price change also depends on the supplier, margins and market conditions.
- From the same date: the Czech Republic also ended the temporary regulation of fuel station margins.
Czech fuel tax changes
Czech diesel excise duty returned to the standard level from 20 July 2026
The Czech Ministry of Finance decided to end the temporary measures from 20 July 2026 as conditions in the fuel market improved and oil price volatility decreased.
Until 19 July 2026, diesel benefited from a temporary partial excise duty relief of CZK 1.939/l. This reduced the effective excise duty from the statutory rate of CZK 9.950/l to CZK 8.011/l.
After the measure expired, the full standard diesel excise duty rate of CZK 9.950/l became applicable again from 20 July 2026.
| Period | Diesel excise duty | Change |
|---|---|---|
| 8 April 2026–19 July 2026 | CZK 8.011/l | Temporary partial excise duty relief of CZK 1.939/l applied |
| From 20 July 2026 | CZK 9.950/l | Excise duty burden increased by CZK 1.939/l |
This is the excise duty change before VAT. Taking Czech VAT into account, the theoretical impact on the final diesel price may reach approximately CZK 2.35 per litre. However, fuel station prices may not change uniformly because they are also affected by oil prices, exchange rates, supply costs and commercial margins.
Fuel price regulation
The Czech Republic also ended fuel station margin regulation
Together with the end of the temporary excise duty reduction, the Czech Ministry of Finance also ended the regulation of fuel station operators’ margins.
This means that from 20 July 2026, fuel station pricing is once again determined more strongly by normal market conditions. As a result, the final price change at fuel stations may not be identical everywhere or take effect at the same time.
Some suppliers may pass the new tax burden into prices immediately, while others may continue selling fuel purchased earlier for a limited period.
Transport companies should assess more than the official excise duty increase. They also need to monitor when and to what extent individual fuel suppliers, fuel station networks and fuel card operators include the change in their commercial prices.
Actual fuel cost
The real cost of diesel is more than the price displayed at the fuel station
The official excise duty increase is CZK 1.939/l, but this does not mean diesel will automatically become more expensive by exactly that amount at every fuel station.
The final fuel cost depends on supplier pricing, commercial discounts, fuel card conditions, VAT and the timing of when the supplier includes the changed excise duty in its prices.
The actual net fuel cost depends on:
- the supplier’s base price;
- the diesel excise duty of CZK 9.950/l;
- VAT;
- potential VAT recovery;
- fuel card conditions;
- commercial discounts;
- fuel station or network margins;
- when the supplier applied the new tax burden;
- the exchange rate if the company keeps its accounts in euros.
| Example diesel volume | Additional excise duty | Theoretical impact including VAT |
|---|---|---|
| 1,000 litres | CZK 1,939 | Approximately CZK 2,346 |
| 10,000 litres | CZK 19,390 | Approximately CZK 23,462 |
| 50,000 litres | CZK 96,950 | Approximately CZK 117,310 |
The calculations show the theoretical direct tax impact. The actual change in supplier pricing may differ.
How UNVERO helps
UNVERO monitors fuel tax and supplier price changes
UNVERO continuously monitors fuel taxation changes across Europe and checks how they are reflected in commercial fuel supplier prices.
When pricing data does not clearly reflect changes in legislation or state support measures, we contact suppliers directly to clarify when and how the changes were applied.
UNVERO calculates the actual net fuel cost by taking into account:
- supplier prices;
- diesel excise duty;
- VAT;
- potential VAT and other tax recovery;
- fuel card conditions;
- commercial discounts;
- exchange rates;
- the start and end dates of temporary government measures.
This enables transport companies to make more accurate fuel purchasing decisions based on the real fuel cost rather than only the price displayed at a fuel station or in a supplier portal.
