Flat-Rate Transport Allowance of CZK 5,000: When Does It Pay Off?

The flat-rate transport expense of CZK 5,000 per month is one of the simplest ways for OSVČ to deduct vehicle running costs. You don't need to keep fuel receipts, you don't need to maintain a mileage log, and you don't need to split your consumption between business and private kilometres. All you need to do is meet a few conditions and you can deduct a fixed amount every month.
But simplicity comes at a price. For OSVČ who drive a lot of kilometres or own an older vehicle with higher running costs, the flat rate may actually leave money on the table. In this article, we'll break down the rules of the flat-rate transport allowance in detail, show you when it pays off and when it doesn't, and compare it with actual expenses using real-world examples.
The legal basis for the flat-rate transport expense is Section 24(2)(zt) of Act No. 586/1992 Coll., on Income Taxes (hereinafter the ITA). The information in this article reflects legislation in force as of February 2026.
What Is the Flat-Rate Transport Expense?
The flat-rate transport expense is a fixed amount that a taxpayer may deduct from their tax base for each full calendar month of the tax period during which they used a road motor vehicle to generate, secure, or maintain taxable income.
In plain terms: instead of proving how much you actually spent on fuel and parking, you deduct a flat amount with no receipts required for those expenses.
Key parameters of the flat-rate transport allowance
| Parameter | Value | |----------|---------| | Full flat rate (exclusively business use) | CZK 5,000 / month | | Reduced flat rate (also private use) | CZK 4,000 / month | | Maximum number of vehicles | 3 per tax period | | Maximum annual deduction (full rate, 1 vehicle) | CZK 60,000 | | Maximum annual deduction (reduced rate, 1 vehicle) | CZK 48,000 | | Maximum annual deduction (full rate, 3 vehicles) | CZK 180,000 |
Conditions for Claiming the Flat Rate
The flat-rate transport expense cannot be claimed unconditionally. You must meet several requirements set out by law.
Who Can Claim the Flat Rate
The flat-rate transport expense may be claimed by:
- OSVČ keeping tax records or full double-entry bookkeeping
- Legal entities (s.r.o., a.s.)
- Taxpayers with rental income (Section 9 of the ITA)
Who Cannot Claim the Flat Rate
Who cannot claim the flat-rate transport expense
The flat-rate transport expense cannot be combined with:
- Percentage-based lump-sum expenses — if you claim expenses as a percentage of income (60%, 80%, etc.), vehicle costs are already included in that percentage allowance
- Flat-rate tax regime — taxpayers in the flat-rate tax regime cannot claim any specific individual expenses
- Employee travel reimbursements — if you claim travel reimbursements for an employee using the same vehicle, you cannot simultaneously claim the flat-rate transport expense for it
Additional Conditions
-
You must actually use the vehicle to generate, secure, or maintain taxable income — the flat rate cannot be claimed for any month in which you did not use the car for business at all (e.g., you spent the entire month abroad without it).
-
You must not allow another person to use the vehicle — in any month for which you claim the flat rate, you must not let another person use the vehicle for private purposes. An exception applies to business trips made by employees or co-operating persons.
-
Same method for the entire year — once you choose the flat rate for a specific vehicle, you must apply it for the entire calendar year. You cannot switch to actual expenses partway through the year, or vice versa.
-
Maximum of 3 vehicles — the flat rate can be claimed for no more than 3 motor vehicles. If you use more cars, you must substantiate actual expenses for the remaining ones.
Full vs. Reduced Flat Rate: CZK 5,000 vs. CZK 4,000
The law distinguishes between two variants of the flat rate depending on how you use the vehicle.
Full Flat Rate — CZK 5,000
The full flat rate applies if you use the vehicle exclusively for business — you never use it for private purposes (shopping, dropping off kids, holidays).
Reduced Flat Rate — CZK 4,000
The reduced flat rate (80% of the full rate) applies if you also use the vehicle for private purposes. This is the reality for the vast majority of OSVČ who own just one car.
Be realistic: most OSVČ qualify for the reduced flat rate
During a tax audit, the tax authority will assess whether a claim of exclusively business use is credible. If your household owns only one car, it is highly unlikely that you never use it privately. The tax inspector knows this and will ask you to prove otherwise. Claiming the full flat rate in such a situation risks having it disallowed entirely.
Our recommendation: if you cannot clearly demonstrate that you have a second car for personal use, claim the reduced flat rate of CZK 4,000. The difference of CZK 12,000 per year (maximum tax saving of CZK 1,800) is not worth the risk of a dispute with the tax authority.
Impact of the Reduced Flat Rate on Other Expenses
If you claim the reduced flat rate, you must also reduce other vehicle-related expenses to 80%:
- Vehicle depreciation — claim 80%
- Insurance — claim 80%
- Repairs and maintenance — claim 80%
- Leasing payments — claim 80%
What the Flat Rate Covers and What It Doesn't
This is critical information that many OSVČ are unaware of. The flat-rate transport allowance replaces only some actual expenses — not all of them.
📊What the flat-rate transport expense covers and what it doesn't
Depreciation alongside the flat rate: yes, but watch the reduction
Alongside the flat-rate transport expense, you can claim vehicle depreciation, insurance, repairs, and other expenses not covered by the flat rate. However, if you are claiming the reduced flat rate (CZK 4,000), you must also reduce these additional expenses to 80%.
Example: The annual depreciation on a car is CZK 50,000. With the reduced flat rate, you can only claim 80% = CZK 40,000.
The Flat Rate and VAT: A Special Rule
If you are a VAT payer, there is an additional advantage. Even when claiming the flat-rate transport expense, you can still reclaim input VAT on fuel purchases. However, you must:
- Hold proper tax documents for each fuel purchase
- Keep records of fuel purchases
- With the reduced flat rate, only reclaim VAT on 80% of the fuel purchased
This rule arises from the fact that the flat rate replaces expenses for income tax purposes, while VAT is governed by its own legislation (Act No. 235/2004 Coll.).
When the Flat Rate Pays Off: A Comparison with Examples
Let's look at some concrete numbers. We'll compare the flat rate against actual expenses for three typical OSVČ profiles.
Example 1: IT Consultant — Low Mileage
Example: IT consultant with low annual mileage
Profile: IT consultant, works mostly from home, drives to meetings 2–3 times a week. Annual mileage: 8,000 km, of which 60% business.
Vehicle: Škoda Fabia 1.0 TSI, fuel consumption 5.5 l/100 km, petrol price CZK 38/l
Actual fuel expenses (business km):
- Business kilometres: 4,800 km
- Consumption: 4,800 × 5.5 / 100 = 264 litres
- Fuel costs: 264 × 38 = CZK 10,032
- Parking (estimate): CZK 3,000
- Total fuel + parking: CZK 13,032
Flat-rate transport allowance (reduced):
- 12 × 4,000 = CZK 48,000
Result: The flat rate is more advantageous by CZK 34,968
Tax saving from the difference (15% rate): CZK 5,245 per year
Example 2: Sales Representative — High Mileage
Example: Sales representative with high annual mileage
Profile: Sales representative, on the road every day across the region. Annual mileage: 45,000 km, of which 80% business.
Vehicle: Škoda Octavia 2.0 TDI, fuel consumption 5.8 l/100 km, diesel price CZK 36/l
Actual fuel expenses (business km):
- Business kilometres: 36,000 km
- Consumption: 36,000 × 5.8 / 100 = 2,088 litres
- Fuel costs: 2,088 × 36 = CZK 75,168
- Parking (estimate): CZK 8,000
- Motorway vignette (80%): CZK 1,280
- Total: CZK 84,448
Flat-rate transport allowance (reduced):
- 12 × 4,000 = CZK 48,000
Result: Actual expenses are more advantageous by CZK 36,448
Tax saving from the difference (15% rate): CZK 5,467 per year
Note, however — with actual expenses, the sales representative must maintain a mileage log, which adds administrative burden.
Example 3: Tradesperson — Medium Mileage, Two Vehicles
Example: Tradesperson with two vehicles
Profile: Plumber, drives to clients and transports materials. Personal car + van. Both vehicles also used privately.
Vehicle 1 — Personal car (Škoda Karoq):
- Annual business km: 12,000
- Consumption 7.0 l/100 km, petrol CZK 38/l
- Fuel: 12,000 × 7.0 / 100 × 38 = CZK 31,920
- Parking: CZK 2,000
- Total (80%): CZK 27,136
Vehicle 2 — Van (VW Caddy):
- Annual business km: 18,000
- Consumption 6.5 l/100 km, diesel CZK 36/l
- Fuel: 18,000 × 6.5 / 100 × 36 = CZK 42,120
- Parking: CZK 1,500
- Total (80%): CZK 34,896
Total actual expenses: CZK 62,032
Flat-rate transport allowance (reduced, 2 vehicles):
- 2 × 12 × 4,000 = CZK 96,000
Result: The flat rate is more advantageous by CZK 33,968
Plus, there's no need to maintain a mileage log for either vehicle — saving approximately 2 hours of admin work per month.

How to Claim the Flat Rate in Your Tax Return
Here's how claiming the flat-rate transport expense works in practice:
📋How to claim the flat-rate transport expense
No mileage log required
The main advantage of the flat rate: you do not need to keep a mileage log. The tax authority cannot require a mileage log for a vehicle for which you are claiming the flat-rate transport expense. You simply need to be able to demonstrate that you actually used the car for business in the relevant months (e.g., invoices showing client addresses, email correspondence, contracts with clients at different locations, etc.).
Common Mistakes When Claiming the Flat Rate
Based on experience from tax audits, here are the most frequent mistakes OSVČ make:
1. Claiming the flat rate for an incomplete month The flat rate applies only to full calendar months. If you started, suspended, or ceased your business activity during a given month, you cannot claim the flat rate for that month.
2. Claiming fuel receipts alongside the flat rate If you are claiming the flat rate, you cannot simultaneously deduct fuel receipts as expenses. Fuel is already included in the flat rate. The only exception is reclaiming input VAT on fuel for VAT payers.
3. Claiming the full flat rate for the only car in the household As mentioned above, the tax authority will question a claim of exclusively business use if your household has just one vehicle.
4. Changing methods mid-year You cannot claim the flat rate from January to June and then switch to actual expenses from July onwards (or vice versa). The choice applies to the entire tax period.
5. Claiming the flat rate for more than 3 vehicles The limit is 3 vehicles. For a fourth vehicle and beyond, you must substantiate actual expenses.
6. Combining with percentage-based lump-sum expenses If you claim expenses at 60% (or any other rate) of income, vehicle costs are already included in that percentage. The flat-rate transport expense cannot be claimed on top of that.
The Flat Rate for Electric Vehicles
As electric vehicles become more common, the question naturally arises of how the flat-rate transport expense applies to an EV. The rules are the same as for combustion-engine vehicles:
- Flat rate of CZK 5,000 (full) or CZK 4,000 (reduced) per month
- Charging costs (electricity) are included in the flat rate — they cannot be claimed separately
- Depreciation, insurance, and repairs can be claimed alongside the flat rate
Electric vehicles and depreciation: an extra bonus
Electric vehicles are depreciated in depreciation group 2 (5 years), the same as regular passenger cars. However, the purchase price of EVs is often higher, which means higher annual depreciation amounts and a larger tax deduction. Combined with the flat-rate transport allowance, the overall tax benefit can be very attractive.
Frequently Asked Questions (FAQ)
Can I claim the flat rate for a vehicle I don't own?
Yes. The flat-rate transport expense can be claimed for a vehicle that is leased (operating lease), borrowed, or owned by your spouse. The key condition is that you actually use it for business.
What if I only use the car for part of the year?
You can claim the flat rate for each full month in which you used the vehicle. For example, if you had the car from April to December, you can claim the flat rate for 9 months (9 × 5,000 = CZK 45,000 or 9 × 4,000 = CZK 36,000).
Can I combine the flat rate with a reimbursement for using a private vehicle?
No. If you as an OSVČ are claiming the flat-rate transport expense, you cannot simultaneously claim the basic wear-and-tear reimbursement and fuel reimbursement under the travel allowance regulations for the same vehicle.
How do I prove I actually used the car for business?
Even though you don't need to keep a mileage log, you should be able to demonstrate business use if asked. Sufficient evidence includes: invoices showing client addresses, meeting notes, email correspondence about appointments, contracts with clients at various locations, and photographs from job sites.
Does the flat rate also apply to motorcycles?
Yes. The law refers to "road motor vehicles", which includes motorcycles. The conditions are the same.
Can I claim the flat rate if I have a car on lease?
Yes, the flat rate can be claimed for vehicles acquired through both finance and operating leases. Lease payments (or rental fees) are claimed separately alongside the flat rate, since the flat rate only covers fuel and parking costs.
Does the car need to be insured in my name?
Not necessarily. The vehicle does not need to be registered in your name. It can be registered to your spouse, a family member, or a leasing company. What matters is that you can demonstrate you use it for business.
How to Calculate Which Option Works Best for You
Calculation: Does the flat-rate transport expense work for me?
How to decide:
- Add up your actual annual expenses on fuel + parking + motorway vignette (only the expenses that the flat rate replaces)
- If you also use the car privately, multiply by your business-use proportion (typically 80%)
- Compare with the flat rate (CZK 48,000 for the reduced rate, CZK 60,000 for the full rate)
Break-even point for the reduced flat rate (CZK 4,000/month):
At an average fuel price of CZK 37/l and consumption of 6 l/100 km:
- Cost per km = 6 × 37 / 100 = CZK 2.22
- Flat rate covers the equivalent of: 48,000 / 2.22 = 21,621 km (business)
- If you drive fewer than 21,621 business km per year, the flat rate pays off
- If you drive more, actual expenses are the better choice
For the full flat rate (CZK 5,000/month):
- Flat rate covers the equivalent of: 60,000 / 2.22 = 27,027 km
Note: Don't forget to add parking fees and the motorway vignette to your actual expenses. And remember that with actual expenses, you must keep a mileage log — which has its own cost in time.
Switching Methods in the Following Year
If you find that you chose the less advantageous method in the current year, don't worry. In the next tax period, you can opt for a different approach. The choice between the flat rate and actual expenses is not permanent — it applies only to the given calendar year.
We recommend doing a quick calculation each December or January:
- Add up your actual fuel and parking expenses for the past year
- Compare with the flat rate
- Choose the more advantageous option for the coming year
