A Guide to Corporate Taxes in Slovenia

What Is the Corporate Tax Rate in Slovenia?

The corporate tax rate in Slovenia is the percentage of a company’s taxable profit that must be paid to the government.

For most businesses, this rate is now higher than it has historically been, affecting both local companies and foreign firms with operations in Slovenia.

• Standard Corporate Income Tax Rate: The main corporate income tax rate in Slovenia is 22% for the period 2024–2028.
• Historical Rate: Before 2024, the standard rate was 19%.
• Multinational Minimum Tax: Large international and large domestic groups in Slovenia are subject to a minimum effective tax rate of 15% under global tax rules.
• Special Exemptions: Certain entities, such as investment funds or pension funds, may qualify for a 0% tax under specific conditions set out in Slovenian law.

To fully understand how the corporate tax rate in Slovenia applies in practice, it helps to examine the breakdown of the components of corporate income tax.

Breakdown of Corporate Income Tax Components

Slovenia’s corporate income tax system comprises several components that contribute to businesses’ overall tax obligations. These include:

• National Corporate Tax: The main corporate income tax is applied to a company’s taxable profits at the national level.
• Local and Municipal Taxes: While Slovenia does not impose specific municipal taxes on corporate income, businesses may still be subject to local taxes depending on their operations and business activities.
• Surcharges: Certain businesses may face additional surcharges, particularly in specific sectors or under specific conditions. These surcharges increase the effective tax rate for qualifying entities.
• Taxable Income: The tax is calculated on a company’s profits after accounting for allowable deductions, such as operating costs, R&D expenses, and other business-related expenses outlined by Slovenian tax law.

Once the components of corporate income tax are clear, the next step is understanding the corporate tax filing requirements in Slovenia.

Corporate Tax Filing Requirements in Slovenia

Filing corporate tax returns in Slovenia involves completing a set of steps with the tax authority through the official electronic system. These practical steps help you stay compliant with company tax filing in Slovenia:

• Filing Deadline: Corporate tax returns must be filed within three months after the end of the tax year, typically by March 31 for calendar-year businesses.
• Required Documents: Submit the corporate income tax return form electronically via the eDavki portal, including necessary attachments like financial statements and proof of deductions.
• Payment: Tax payments are due within 30 days of filing. Payments are made via bank transfer to FURS, with advance payments based on the prior year’s liability, typically made monthly or quarterly.
• Digital Filing: All returns must be filed through the eDavki portal, requiring a digital certificate or registered access for submission.
• Extensions: Extensions can be requested if needed, but must be submitted before the original deadline and typically extend up to three months.
• Penalties: Late filings or payments result in penalties and interest, and potential audits if there are repeated delays or discrepancies.

After reviewing the filing requirements, it is equally important to be aware of the tax year and payment deadlines in Slovenia.

Tax Year and Payment Deadlines in Slovenia

In Slovenia, understanding the corporate tax year and associated payment deadlines is crucial for businesses to stay compliant and avoid penalties. Here’s an overview of the standard tax year period and key payment deadlines in Slovenia:

• Standard Corporate Tax Year: Generally aligns with the calendar year, running from January 1 to December 31. Companies that use a fiscal year rather than the calendar year must file their tax returns based on their fiscal year.
• Payment Deadlines: Corporate tax payment deadlines in Slovenia fall within 30 days of filing the annual tax return. For businesses using the calendar year, this means payments are due by March 31 of the following year.
• Quarterly Payments: Businesses must make advance quarterly tax payments based on the prior year’s tax liability. These payments are due at the end of each quarter, with payments made within 20 days after the period they cover.
• Monthly Installments: Businesses that identify higher tax liabilities may be required to make monthly advance payments based on the prior year’s tax liability or current projections.

Beyond deadlines, businesses must also account for withholding taxes and other business taxes in Slovenia.

Withholding Taxes and Other Business Taxes in Slovenia

Businesses in Slovenia must also account for withholding taxes on certain payments and other notable taxes that affect operations and pricing. These taxes apply when you make certain payments or engage in taxable business activities.

Withholding Tax Rates:

• Dividends: A 15% withholding tax generally applies to dividends paid by a Slovenian company to non-resident recipients. The rate may be reduced or eliminated under an applicable double taxation treaty or EU directive, subject to meeting the required conditions.
• Interest: Interest paid by a Slovenian entity to a non-resident is generally subject to 15% withholding tax. Reduced rates or exemptions may apply under a double taxation treaty or specific domestic exemptions.
• Royalties: Royalties paid to non-resident recipients are generally subject to 15% withholding tax. The rate may be reduced under an applicable double taxation treaty or eliminated under EU rules when certain conditions are met.

Value Added Tax (VAT):

• Slovenia applies a standard VAT rate of 22% for most goods and services. A reduced rate of 9.5% applies to certain categories, such as books, pharmaceuticals, and some basic food products.

Capital Gains Tax:

• Capital gains derived from the sale of shares or other business assets are taxed. However, certain exemptions may apply depending on the asset type and holding period.

Alongside these obligations, companies should consider the available corporation tax in Slovenia, along with incentives, deductions, and exemptions.

Corporate Tax Incentives, Deductions, and Exemptions

Slovenia’s corporate tax system gives businesses several ways to reduce their taxable income through targeted incentives, deductions, and exemptions. These provisions are designed to encourage investment, innovation, and economic growth within the country.

1. R&D Tax Deductions

Slovenia provides a 100% deduction for qualifying research and development (R&D) expenses. Companies that invest in R&D activities can reduce their taxable income by the full amount of these expenses. This is a crucial incentive for businesses focused on innovation and technology.

2. Investment Incentives

Companies can claim an additional 40% deduction for qualifying investments in equipment and intangible long-term assets. These corporate tax incentives in Slovenia apply to eligible capital expenditures and are subject to overall limits linked to taxable profit.

3. Regional Incentives

Although there are no broad region-wide corporate tax rate reductions under the core tax code, municipalities may offer tailored local support packages. These may include access to industrial land, utility cost relief, or negotiated investment incentives for specific projects.

4. Other Deductions and Allowances

Businesses may deduct ordinary expenses necessary for generating revenue, along with regulated depreciation and amortisation.

Certain voluntary pension contributions, employment-related incentives, and qualified charitable donations may also be deductible, subject to statutory limits.

Finally, understanding Slovenia’s international tax treaties and double taxation avoidance agreements helps businesses manage cross-border tax exposure effectively.

International Tax Treaties and Double Taxation Avoidance

Slovenia has signed a range of double taxation treaties (DTTs) with numerous countries to prevent businesses from being taxed twice on the same income.

These treaties play a critical role for companies operating internationally by clarifying tax obligations and reducing the risk of dual taxation.

Overview of DTTs:

• Slovenia has signed DTTs with more than 50 countries, including major trading partners such as the United States, Germany, France, and Italy.
• These treaties help clarify which country has the right to tax specific types of income, such as dividends, royalties, and interest.

Avoiding Double Taxation:

• Businesses operating in multiple countries can use DTTs to avoid paying taxes twice on the same income.
• If a Slovenian company earns income from a foreign subsidiary, the tax treaty determines whether Slovenia or the foreign country can tax the income.
• Generally, the country where the income is generated has the first right to tax, and Slovenia offers relief through tax credits or exemptions.

Relief Mechanisms:

• Tax Credits: Companies can offset foreign tax paid against their Slovenian tax liability, reducing overall tax burden.
• Exemptions: Certain types of income may be exempt from Slovenian tax if taxed in the foreign jurisdiction under the terms of the treaty.
