The fixed assets register (ewidencja środków trwałych) is a mandatory record of business assets. If you have equipment above 10,000 zł — you must depreciate it and maintain the register.

In this guide, I explain how the fixed assets register works for a sole proprietorship (JDG) in Poland in 2026.

Fixed assets register — registration and depreciation

Fixed assets worth over 10,000 zł net must be registered and depreciated. Passenger cars have an additional limit of 150,000 zł for tax purposes. Depreciation rates depend on the KŚT group (Classification of Fixed Assets).

Registration threshold
10 000 zł
Fixed assets below 10,000 zł can be expensed in a single deduction — without registration or depreciation.
Car limit
🚗 150 000 zł
For passenger cars — up to this amount depreciation is fully deductible. Above the limit, part of the write-offs is not a cost.

KŚT groups and depreciation rates

0
Buildings and premises
2.5%
1
Structures
4.5%
2
Machinery and equipment
10%
3
Vehicles, transport means
20%
4
Tools, instruments
20%
6
Computer equipment
30%

Important: For passenger cars above the 150,000 zł limit, the excess is not deductible. In linear PIT you cannot use the degressive method. Computer equipment has the highest rate — 30% per year.

Want to correctly set up your fixed assets register?

Let's check →

Rates per the schedule of annual depreciation rates (Appendix 1 to the PIT/CIT Act). Passenger car limit: 150,000 zł. Single-expense threshold: 10,000 zł net (Art. 22d of the PIT Act).

What is a fixed asset?

A fixed asset is business property that:

  1. Is owned or co-owned by the entrepreneur
  2. Serves the business activity
  3. Has an expected useful life of more than 1 year
  4. Has an initial value of more than 10,000 zł net

Examples: computers, cars, machinery, furniture, equipment, perpetual licenses.

The 10,000 zł net threshold

Below 10,000 zł net

  • One-time deduction in the month of purchase (tax scale/flat tax)
  • You do not enter it in the fixed assets register
  • Direct cost

Above 10,000 zł net

  • You must depreciate it (spread the cost over years)
  • You enter it in the fixed assets register
  • Depreciation rate according to KŚT (Klasyfikacja Środków Trwałych — Classification of Fixed Assets)

Fixed Assets Register — Template

Each fixed asset must be entered in the register with the following data:

  1. Inventory number — LP/year (e.g., 1/2026)
  2. Name — e.g., "Passenger car Toyota Corolla 2024"
  3. Date of acquisition — date of purchase/transfer
  4. Initial value (WP) — purchase price + additional costs
  5. KŚT — Classification of Fixed Assets (group code)
  6. Depreciation rate — annual rate per KŚT
  7. Annual depreciation — WP × rate
  8. Prior-year depreciation — cumulative
  9. Current-year depreciation — monthly/annual
  10. Book value (net) — WP − cumulative depreciation

KŚT — Classification of Fixed Assets

KŚT is a coding system for fixed assets with 8 groups:

| KŚT Group | Type of asset | Example rate | |-----------|--------------|-------------| | 0 | Land and real estate | Not depreciated | | 1 | Buildings and structures | 1.5–10% | | 2 | Machinery and equipment | 10–20% | | 3 | Boilers and engines | 20% | | 4 | General-purpose machinery and equipment | 10–20% | | 5 | Specialized machinery | 10–20% | | 6 | Tools, instruments | 20% | | 7 | Technical means of transport | 20% (passenger cars) | | 8 | Other fixed assets | 20–30% |

Most commonly: computers → KŚT Group 4, rate 20%.

Depreciation — How does it work?

Straight-line method (most common)

  • Fixed annual depreciation rate (per KŚT)
  • Monthly depreciation = (WP × rate) / 12

Example: computer 15,000 zł net

  • KŚT Group 4, rate 20%
  • Annual depreciation: 15,000 × 20% = 3,000 zł
  • Monthly depreciation: 3,000 / 12 = 250 zł
  • Depreciation period: 5 years

Declining-balance method

  • Higher rate in the first years (multiplier × KŚT rate)
  • Only for machinery and equipment (Groups 3–6)
  • Accelerates costs in the first years

Car Depreciation

Value limit: 150,000 zł (combustion engine)

  • You depreciate up to 150,000 zł of initial value
  • Above 150,000 zł — you cannot depreciate (with exceptions)
  • Electric: limit 225,000 zł

Rate: 20% (KŚT Group 7)

  • Passenger car: 20% per year
  • Example: car 100,000 zł → depreciation 20,000 zł/year (5 years)

No. Depreciation limit: 150,000 zł (combustion engine), 225,000 zł (electric).
