Company expenses in Poland: what can be deducted and what is strictly prohibited
Company expenses in Poland are one of the most sensitive issues for entrepreneurs. Proper classification of expenses directly affects the amount of tax due, the outcome of a tax audit, and the liability of the management board.
From legal practice, I can say that most problems arise not because of large amounts, but due to incorrect qualification of expenses. What may seem logical to a business owner is not always accepted by the tax authorities.
Company expenses in Poland
Under Polish tax law, a deductible expense is a justified and properly documented cost incurred in order to obtain, secure, or maintain income.
The key criteria are:
- economic justification;
- direct connection with business activity;
- proper documentation (invoice, contract, proof of payment).
What company expenses can be deducted
Typical and generally safe deductible expenses include:
- office or warehouse rent;
- utility payments;
- accounting and legal services;
- equipment, devices, and software;
- licenses, subscriptions, CRM systems, and other online tools;
- advertising, marketing, website, domain, and hosting;
- business travel and company transport;
- training for employees and management related to business activity.
In the case of high-value assets (vehicles, equipment, machinery), depreciation applies — meaning the cost is gradually included in expenses over several years.
Employee and management expenses
Company expenses may also include:
- salaries;
- social security contributions (ZUS);
- bonuses and performance rewards;
- medical insurance;
- business travel expenses.
The key requirement is proper documentation through employment or civil law contracts and supporting financial records.
Which company expenses in Poland cannot be deducted
Tax authorities do not recognize personal expenses of owners or board members, even if paid from the corporate account.
Such expenses include:
- private housing;
- personal meals;
- holidays and family trips;
- clothing (unless it qualifies as workwear);
- personal mobile phones without business justification;
- fines and penalties.
These expenses may be reclassified as hidden income, resulting in additional tax assessments, penalties, and interest.
Mixed-use expenses: higher risk area
If an expense has both business and private use (for example, a car or phone), only partial deduction is allowed — proportionally to actual business use.
Without clear documentation, such expenses often raise concerns during tax audits.
Official guidance on deductible expenses is available on the Polish Ministry of Finance website: podatki.gov.pl.
Legal conclusion
Company expenses in Poland are not about reducing tax at any cost — they are about compliance with the law and the ability to defend your position during a tax audit.
Before deducting any unusual expense, ask yourself a simple question: would I be able to logically justify its economic purpose before a tax inspector?
If in doubt, it is advisable to seek professional tax and legal consultation in Poland to minimize risks and protect your company from financial consequences.
