Accounting for income tax

Frequent changes in tax legislation, complicated regulations and their differing interpretations often cause uncertainty. They expose businesses not only to wrong decisions, but also to the risk of not applying the provisions of the Corporate Income Tax Act.
This is why CIT compliance is becoming an increasingly complex and necessary service area for businesses. Without constantly updating the knowledge of the accounting team, business owners take unnecessary risks of irregularities in the company's accounts, exposing themselves to significant financial consequences in the form of tax arrears.

Accounting for CIT income tax


According to the law, CIT taxpayers are legal entities, capital companies in organization, limited joint-stock partnerships and capital groups that include at least two commercial companies. The obligation to file an annual tax return applies to all corporate income taxpayers except those exempt from tax under of the CIT Law.
Entities whose headquarters and management are located in Poland are required to tax all income, regardless of where it is earned. However, if the company does not have a management or registered office in Poland, tax obligation applies only to income earned in our country.
The CIT gap, i.e. the difference between the revenue due to the state budget and its real income, can result in increased controls on the entrepreneur. With our knowledge of international tax truth we will successfully guide you through the audit process. As part of our CIT compliance service, we will identify areas of risk, help you complete the necessary documentation and facilitate contacts with the relevant authorities.

CIT tax reviews

It can cover all taxes or only specific areas, e.g., the area related to withholding tax obligations.
The condition for conducting a tax review is to analyze the documentation and tax procedures implemented by your company.
