What is the NRA, what returns and deadlines apply to a small company, and how to use the electronic portal — explained in plain language.
29 October 2026
The National Revenue Agency (NRA) is the institution to which you submit your company's annual tax return, transfer payroll contributions, and declare VAT if you are registered under the VAT Act. For the owner of an EOOD, OOD, or ET, this is the main point of contact with the state on tax and social security matters — and most communication today happens online rather than at a counter.
The agency administers corporate tax (under the Corporate Income Tax Act - ZKPO), personal income tax (under the Personal Income Tax Act - ZDDFL), social security contributions under the Social Insurance Code (KSO), and VAT under the VAT Act. Besides accepting returns and payments, the NRA also carries out checks — both desk audits and on-site inspections — when the data in submitted documents doesn't match information it holds from third parties: banks, other institutions, providers of electronic services.
The annual tax return under the Corporate Income Tax Act is filed between March 1 and June 30 of the year following the reporting year. The corporate tax due must also be paid within the same deadline — by June 30. This applies regardless of whether the company was actively operating, as long as it was subject to filing under the law. The return is submitted via the NRA's electronic portal using a qualified electronic signature (QES) or a personal identification code (PIC).
If the company has employees under employment contracts, the employer pays social security contributions by the 25th of the month following the month for which they are due. From 2026, the contribution payable by the insured person is 13.78% (10.58% for pension insurance plus 3.2% health insurance), and the contribution payable by the employer is 18.52%, plus a contribution for occupational accidents and diseases (TZPB) ranging between 0.4% and 1.1%, depending on the main economic activity.
The maximum insurable income is EUR 2,111.64 until July 31, 2026, rising to EUR 2,300 from August 1, 2026. For self-insured individuals — sole traders (ET owners), EOOD managers without an employment contract, freelancers — the minimum insurable income is EUR 550.66 until July 31 and EUR 620.20 from August 1, 2026.
When profit is distributed to an individual, a dividend tax of 5% is due. Its declaration and payment are made to the NRA according to the deadlines under the Personal Income Tax Act — if you are unsure of the exact date of the distribution decision, it's best to check with a current accountant before transferring the amount.
If the company purchases goods from a supplier in another EU member state and the total value of these acquisitions exceeds EUR 10,000 in a calendar year, an obligation to register for VAT on this basis arises, even if the company's turnover is otherwise below the mandatory registration threshold. It is advisable to monitor this threshold on an ongoing basis, not at year-end.
Most communication with the agency happens online:
Through the portal you can also check whether you have outstanding obligations before applying for a loan, a public procurement contract, or a certificate of good standing — most institutions require a certificate from the NRA confirming no outstanding liabilities.
The NRA cross-checks submitted returns against data from banks, sales software providers, other administrations, and foreign tax authorities through automatic exchange of information. A discrepancy between declared revenue and account movements, or between declared supplies and data from counterparties, usually leads to a request for documents or a desk audit. Responding on time with correct documents usually resolves the matter without escalating to a full tax audit.
The general rules above cover most small companies, but some cases require individual assessment:
In these situations, it is better to act with a current accountant or ask the NRA directly, rather than guess — a mistake in a return filed with the agency is easier to correct before it is submitted than afterward.
