Estonian CIT in Poland: reviewing hidden profits and shareholder payments

Reviewed: 13 October 2026 · Polish law and taxation

A Polish company using Estonian CIT can face tax even when it declares no dividend. The regime also taxes hidden profits, a statutory category covering certain benefits connected with the right to share in profits. Payments to owners therefore need a process that starts before the contract is signed or the transfer is made. A year-end review may arrive after a monthly liability has already arisen.

Read the Polish definition in full

Article 28m(3) of the Polish CIT Act covers cash and non-cash benefits, including paid, partly paid and free benefits. The recipient may be a shareholder or a relevant related party, directly or indirectly. The benefit must be connected with the right to participate in profits. The legislation gives examples rather than an exhaustive list, so a contract label cannot determine the result by itself.

The review should identify what the company actually receives and why it enters the arrangement. A genuine operational requirement must be distinguished from value transferred because of the recipient's ownership position. Related-party status alone does not make every payment a hidden profit. Equally, an invoice and a market-rate price do not answer every question raised by the statutory test.

Separate the directions of financing

The legislation expressly addresses loans granted by the company to its shareholders or parties related to them. It separately addresses interest, commissions, remuneration and fees on financing provided to the company by the specified parties. The direction of the loan and the nature of the payment are therefore critical facts, rather than administrative details.

Repayment by the company of shareholder-loan principal falls within a statutory exclusion. Interest should not be treated as principal simply because both are transferred together. Before payment, the finance team should reconcile each amount with the agreement, outstanding balance and relevant dates. A payment reference such as “shareholder settlement” may conceal several categories that require different tax treatment.

Rent and services require business evidence

Property leases, management services and other owner-provided services should be supported by evidence of need, delivery and terms. A pricing benchmark is useful, but it does not establish the complete hidden-profit analysis. Ask whether the company would enter a comparable arrangement with an independent supplier and examine how the company obtained the assets necessary to operate.

Certain employment and personal-service remuneration is excluded only within statutory limits. Company cars and other assets raise separate questions about exclusive business use and applicable exclusions. Polish Estonian-CIT treatment should not be inferred automatically from a VAT deduction percentage or from the ordinary-CIT rules for deductible expenses. These are different tests with different purposes.

Illustrative example: an owner’s production building

A manufacturer leases its premises from an individual shareholder. The rent matches comparable market offers. The team still collects the lease, production requirements, building-use history and allocation of maintenance responsibilities. It also examines why the business was organised in this way. This evidence supports an assessment of the particular arrangement; the example does not establish that every shareholder lease is either taxable or exempt.

Private use: identify the beneficiary and tax category

Private use of an asset requires distinguishing a hidden profit from expenditure unrelated to business. The beneficiary is one relevant factor. Article 28m excludes 50% of specified expenditure and depreciation from the relevant category in certain mixed-use cases; this is not a universal rule for every private payment. The taxpayer bears the burden of demonstrating exclusive business use. Keep usage rules and evidence of actual use rather than relying solely on an employee’s declaration.

Put a review before the payment run

1. Map payments and benefits involving shareholders and related parties.
2. Separate principal, interest, rent, services and private asset use.
3. Document business need, actual delivery and pricing.
4. Check the relevant statutory exclusions and limits.
5. Assign reporting responsibilities and payment deadlines.

Tax on hidden profits is generally payable by the twentieth day of the month following the payment, expenditure or performance of the benefit. Ongoing information flow matters. Provide TLP with a list of shareholder contracts and payment categories for a targeted review of their classification and supporting evidence. The Polish analysis should be coordinated separately with any tax consequences for a shareholder resident abroad.
