In 2026, the tax service tracks unofficial apartment rentals through several channels at once – from bank transfers to complaints from neighbors through electronic services. It has become much more difficult to hide rental income, and fines reach half the amount of the arrears.
Renting an apartment without a contract and paying taxes in 2026 is becoming increasingly risky. The tax service has mastered several tools at once to detect shadow landlords, and the principle of “nobody knows” no longer works.
As reported with reference to the comment of the managing partner of JSC “Law Company “WINNER””, lawyer Igor Yasko, regular card payments, payment traces or statements from neighbors are enough – and the tax service begins an inspection.
How the tax service detects shadow rent
The most typical channels for detecting unofficial housing rentals are bank transactions and regular transfers. If the owner’s card receives the same amounts from different people every month, this immediately attracts the attention of the tax service.
The second powerful tool is digital traces on ad platforms. Apartment rental announcements on sites like OLX, LUN, or DOM.RIA, active correspondence with potential tenants – all this can become an evidentiary base. Separately, the tax office receives information through complaints from third parties – neighbors who have noticed a regular change of residents, or tenants themselves who are dissatisfied with the living conditions. A complaint can be filed through the electronic services of the State Tax Service.
What are the fines?
If the tax office establishes the fact of non-declaration of rental income, the owner will be charged an additional 18% of personal income tax and 5% of military duty – a total of 23% of the amount received. A fine of 25% of the amount of the arrears is added to this, and in case of a repeated violation – already 50%. Plus a penalty for each day of delay.
In the case of significant amounts and a systematic nature of the violation, the case may move into the realm of criminal liability for tax evasion. A neighbor’s complaint in itself does not mean an automatic fine, but it almost always triggers an inspection and collection of evidence.
How to legalize a lease without overpayments
The lawyer identifies three main models of legal housing rental:
Official rental as an individual. The owner submits an annual declaration of property status and income, pays 18% personal income tax and 5% military duty. The tax is paid within 40 days after the end of the quarter.
Registration of an individual entrepreneur on a single tax. Suitable if the income is stable and the apartment is rented out regularly. The single tax rate is much lower than 23% – depending on the individual entrepreneur group.
Special regime for platforms. A separate tax mechanism that allows you to pay tax through the intermediary platform itself.
According to Igor Yasko, the main rule of 2026 is simple: legalization should cost less than the risk of fines, additional charges, and a dispute with the State Tax Service. If the lease is irregular and without a service component, an official lease from an individual may be simpler. For a stable flow of tenants, it is worth calculating the FOP model.
How to officially register a lease – step by step
To avoid fines, you need to:
Conclude a written lease agreement with the tenant (notarization is not required, but desirable).
Register the agreement with the tax office at the place of residence or file an income declaration.
Pay tax quarterly – 18% personal income tax + 5% military duty from the amount of rent.
Or register an FOP (2nd group) through “Diya” or the Central Tax Service and pay a fixed single tax monthly.
The tax return for the reporting year is filed by May 1 of the following year, and the tax liability is paid by August 1.
