Slovakia works on a March cycle with built-in extensions. The corporate income tax return is due at the end of the third month after year-end, and a company can file a deferral notice to move the date by up to six months. The financial statements follow the same cycle, and the company files them in a public register. Because extensions are routine, the main risk is forgetting that the deferral must be requested before the standard date.

This guide covers the limited liability company (spoločnosť s ručením obmedzeným, s.r.o.), the usual vehicle for a foreign-owned subsidiary, and notes where the joint-stock company (a.s.) and a branch differ. It is written for founders and for legal, finance and operations teams.

Updated November 9, 2026. Slovak rates changed in 2025 and the sources describe the statement and approval periods differently, so this guide separates the standard dates from the deferred dates and tells you where to confirm them with the Financial Administration and the Register of Financial Statements.

Entity compliance Slovakia: the quick answer

• File the corporate income tax return and pay the tax by 31 March for a calendar-year company, or file a deferral notice by that date to extend the deadline.

• A deferral generally extends the return to 30 June for Slovak income and to 30 September where the company has foreign-source income, according to the tax administration reminders and professional sources.

• Prepare double-entry financial statements and file them in the Register of Financial Statements, with the date tied to the tax return deadline in practice.

• Keep beneficial owner data current, and file VAT, payroll and other periodic returns on their own calendars.

What determines a Slovak company's compliance requirements?

Every s.r.o. keeps double-entry books and files a tax return, even with no income, and a zero return still triggers the minimum tax according to professional sources. Companies above size limits need a statutory audit, and the audit and the annual report follow a longer period, according to one professional source. Micro entities can use simplified statements.

Tax rates changed from 2025. Professional sources describe a three-tier structure: 10 percent on taxable income up to EUR 100,000, 21 percent between EUR 100,000 and EUR 5 million, and 24 percent above EUR 5 million. A minimum tax on legal entities also applies. Because the tier is based on income, check the rate for your company each year.

Annual entity requirements in Slovakia: the core checklist

1. Financial statements

The statements include a balance sheet, a profit and loss account and notes. Professional sources describe filing them electronically in the public register at the Ministry of Finance, and some sources describe a three-month preparation period while another describes six months from year-end as the outer limit for the register filing, so confirm the date used by your accountant. If a company defers its tax return, the statements deadline moves with it, according to one professional source.

2. Shareholder approval

The general meeting approves the statements and decides on profit. The Commercial Code sets the period, which one source gives as within one year of the reporting period for approval, but practical timing follows the filing date, so hold the meeting early enough to file on time. Keep minutes and the signed set.

3. Corporate income tax return

The return is filed electronically with no attachments, and the tax is due by the filing date. The standard date for the 2025 tax year was 31 March 2026. A deferral notice filed by that date extends the return, with a limit of 30 June 2026 for income from Slovakia only and 30 September 2026 where income from abroad is involved. The tax administration reminded taxpayers that 30 September 2026 was the final date for those deferred returns, and that the resulting tax had to be paid by the same date.

4. Beneficial owners

Slovak companies disclose beneficial owners in the register of legal entities, and professional sources describe updates within about 60 days of a change, so confirm the period. Keep it consistent with the shareholder records.

5. Related parties

Related-party transactions need arm's-length terms. Larger groups prepare transfer pricing documentation, and interest limitation and thin-capitalisation style rules can restrict deductions. Document intercompany loans, management fees and royalties with contracts.

Tax and indirect tax obligations

The standard VAT rate is 23 percent from 2025, with reduced rates of 19 percent and 5 percent for selected supplies, according to a professional source. VAT registration is mandatory above EUR 50,000 in annual turnover, according to a professional source. Returns are filed monthly or quarterly, generally by the 25th of the following month, and a control statement accompanies the return.

Employers file monthly payroll and social contribution reports. Dividends to foreign shareholders can attract withholding tax, with relief under treaties and EU rules when documents are in place. Payments to residents of non-contracting jurisdictions may be taxed at higher rates.

Foreign-owned subsidiaries

Foreign persons can own Slovak companies. An s.r.o. needs at least one member and up to 50, one or more managing directors, a registered office in Slovakia and share capital of EUR 5,000, according to professional sources. A sole member cannot be the sole member of another s.r.o. Foreign corporate members provide apostilled documents with sworn translations.

Banks apply due diligence to foreign-owned accounts and ask for beneficial owner evidence. Check sector approvals and any screening rules for your investment.

First-year and event-triggered obligations

In the first year, the company is registered in the Commercial Register, receives its tax number, registers for VAT if required, registers with the social insurance agency and health insurers if it hires, files its beneficial owner data and opens a bank account.

Events that trigger filings include a change of managing director, a change of members, a capital change, a change of registered office, a change of articles, a merger and a liquidation. Most are registered with the Commercial Register, and ownership changes affect the beneficial owner register.

Employment and local requirements

Slovak employers register employees with the social insurance agency and health insurers, pay contributions and withhold income tax. Employees have written contracts, statutory annual leave of at least four weeks, notice rights tied to service and protection against dismissal. Many foreign-owned subsidiaries use a local payroll provider.

Record-keeping and governance in Slovakia

The Accounting Act sets retention periods for books and documents, and professional sources commonly place them at five to ten years depending on the document, so ask your accountant for the schedule. Keep the signed statements, the general meeting minutes, copies of the deferral notice, tax payment proofs and the register confirmations. A foreign parent should note the deferral decision in writing each year, since a missed notice means the 31 March date applies.

Build a compliance calendar for Slovakia

A compliance calendar turns the rules above into dated tasks with named owners. Start from the financial year-end and the incorporation anniversary, then add the recurring monthly and quarterly items. Review it each quarter, because deadlines, extensions and registry systems change.

• January to March: close the books and decide whether to file a deferral notice.

• By 31 March: file the tax return and pay tax, or file the deferral notice.

• By 30 June: file a deferred return where the income is only from Slovakia.

• By 30 September: file a deferred return where the company has foreign-source income.

• In line with the tax return date: file the financial statements in the register.

• Monthly or quarterly: VAT, the control statement and payroll reports.

Common mistakes

• Missing the deferral notice date of 31 March.

• Assuming the extension applies automatically.

• Forgetting the minimum tax on a loss-making or zero return.

• Filing the statements without moving them with a deferred return.

• Using the wrong CIT tier after profit growth.

• Letting the beneficial owner data go out of date.
