What is Depreciation (Amortyzacja)?
Depreciation -- known in Polish as amortyzacja -- is the process of gradually allocating the cost of a fixed asset or intangible asset against taxable income over its useful life. When a business owner in Poland purchases equipment, a vehicle, a computer, or software worth more than 10,000 PLN net, they cannot deduct the full amount as a business expense immediately. Instead, the cost is spread across months or years corresponding to the asset's expected useful life.
Depreciation serves two essential purposes. First, it reflects the genuine economic wear and tear on assets -- machines age, buildings deteriorate, and software becomes obsolete. Second, it allows for a rational distribution of tax burdens over time, which is critical for maintaining business cash flow.
The legal framework for depreciation in Poland is set out in the PIT Act (Personal Income Tax, Articles 22a-22o) and the CIT Act (Corporate Income Tax, Articles 16a-16m).
What Can Be Depreciated?
Fixed Assets (Srodki Trwale)
Assets eligible for depreciation must meet all of the following criteria simultaneously:
- They are owned or co-owned by the taxpayer.
- They were acquired or manufactured by the taxpayer.
- They are complete and fit for use on the date they are put into service.
- Their expected useful life exceeds one year.
- They are used for purposes related to the business activity.
Common examples include buildings and premises, machinery and equipment, vehicles, computers and office equipment, and furnishings.
Intangible Assets (Wartosci Niematerialne i Prawne)
This category includes software licenses, patents, copyrights, know-how, and goodwill. Intangible assets may only be depreciated using the straight-line method.
What Cannot Be Depreciated?
The following items are excluded from depreciation: land and perpetual usufruct rights to land (with the exception of capital expenditures on third-party fixed assets), works of art and museum exhibits, assets that are not in use due to business suspension, and assets with an initial value not exceeding 10,000 PLN net -- the latter may be expensed in full immediately.
Depreciation Methods
Straight-Line Method (Metoda Liniowa)
This is the most common and simplest method. It involves making equal depreciation charges throughout the entire depreciation period. The annual depreciation rate is fixed and derives from the Schedule of Depreciation Rates, which is an appendix to the income tax acts.
Example: A business owner purchases a passenger car with an initial value of 100,000 PLN. The depreciation rate for passenger cars is 20% per year. The annual depreciation charge is 20,000 PLN, and the car will be fully depreciated after 5 years. The monthly charge amounts to 1,666.67 PLN.
Declining Balance Method (Metoda Degresywna)
The declining balance method allows for higher deductions in the early years of an asset's useful life. In the first tax year, the rate from the Schedule is multiplied by a coefficient of up to 2.0. In subsequent years, the charge is calculated on the net book value (initial value minus accumulated depreciation) using the same coefficient.
When the annual declining balance charge falls below what the straight-line charge would be, the taxpayer switches to the straight-line method from the following year.
Important: The declining balance method cannot be applied to buildings, structures, intangible assets, or passenger cars.
Units-of-Production Method
A less commonly used method where the depreciation charge depends on the intensity of use of the fixed asset -- for instance, the number of kilometers driven or machine operating hours. It requires documentation of actual utilization.
Key Depreciation Rates
Depreciation rates are defined by the Classification of Fixed Assets (KST) and the Schedule of Annual Depreciation Rates. Here are the most important ones:
| Asset type | Annual rate | |---|---| | Non-residential buildings | 2.5% | | Residential buildings | 1.5% | | Computers and IT equipment | 30% | | Passenger cars | 20% | | Furniture and office equipment | 20% | | General-purpose machinery | 10-18% | | Computer software | 50% |
Taxpayers may apply individual rates in certain cases -- for example, for used or upgraded fixed assets, provided they meet the statutory requirements regarding minimum depreciation periods.
One-Time Depreciation
Low-Value Assets
Fixed assets with an initial value not exceeding 10,000 PLN net can be charged directly to tax-deductible expenses in the month they are put into use, without the need to maintain a fixed asset register for those items.
One-Time Depreciation Under De Minimis Aid
Small taxpayers (revenue up to 2 million EUR per year) and entrepreneurs starting a new business may take advantage of one-time depreciation for fixed assets in KST groups 3-8 (machinery, equipment, transport vehicles excluding passenger cars) up to a combined limit of 50,000 EUR per year. This constitutes a form of de minimis state aid.

Fixed Asset Register
Every entrepreneur making depreciation charges must maintain a register of fixed assets and intangible assets. The register should contain at minimum:
- a sequential number,
- the date of acquisition and the date of acceptance for use,
- identification of the purchase document,
- the name of the fixed or intangible asset,
- the KST symbol,
- the initial value,
- the depreciation rate,
- the updated initial value (if applicable),
- the date of disposal or liquidation and the reason.
Failure to maintain a proper register may result in the tax office challenging depreciation deductions during an audit.
Depreciation and Reporting Obligations
Depreciation charges are reported in the annual PIT tax return (e.g., PIT-36 or PIT-36L) as a component of tax-deductible expenses. CIT taxpayers include them in the CIT-8 return. Information about fixed assets may also be subject to verification through JPK -- tax authorities have the right to request JPK_KR (accounting books) or JPK_EWP (revenue records) files.
Common Mistakes Made by Business Owners
- Depreciating land -- land is not subject to depreciation, even if it was acquired together with a building. The value of the building and land must be separated.
- Incorrect KST classification -- assigning the wrong KST symbol leads to applying an incorrect depreciation rate.
- Ignoring the passenger car limit -- since 2019, depreciation charges on passenger cars cannot exceed the amount calculated on a value of 150,000 PLN (225,000 PLN for electric vehicles).
- No register -- making depreciation charges without formally entering the fixed asset in the register.
- Depreciating below the threshold -- unnecessarily depreciating assets worth less than 10,000 PLN instead of expensing them immediately.
Summary
Depreciation is one of the fundamental tax optimization mechanisms available to every business owner in Poland. Proper application of depreciation rules allows you not only to legitimately reduce the tax base but also to accurately reflect the value of your company's assets. The choice between straight-line, declining balance, or one-time depreciation should be a deliberate decision, taking into account the nature of your business, the types of assets acquired, and your financial situation.
If you have doubts about correctly accounting for depreciation, it is worth consulting an accounting firm or tax advisor who can help you select the optimal depreciation strategy.
