Croatia Corporate Tax Guide 2026
Croatia's corporate income tax (CIT, porez na dobit) features a reduced 10% rate for small enterprises (annual revenue ≤ EUR 1 million and assets ≤ EUR 1 million) and a standard 18% rate for larger companies. Special incentives include 0% CIT for 5 years in free zones, 50% CIT relief for major investment projects, and generous R&D tax incentives. Croatia has been an EU member since 2013.
Corporate Income Tax Rates 2026
Croatia applies a two-tier CIT system depending on the size of the taxpayer:
- 10% rate — for small enterprises with annual revenue ≤ EUR 1 million and assets ≤ EUR 1 million
- 18% rate — for all other enterprises exceeding the small enterprise thresholds
The thresholds are based on the previous tax year's data. A company that qualifies as a small enterprise in one year but exceeds the thresholds in a subsequent year moves to the 18% rate. The CIT is charged on the taxable profit (accounting profit adjusted for tax purposes). Capital gains are included in taxable profit at the applicable CIT rate (10% or 18%). Losses can be carried forward for 5 years. Dividends received from Croatian and EU subsidiaries are generally exempt from CIT. Compare with personal IIT rates →
Free Zones and Investment Incentives
Croatia offers significant tax incentives for qualifying investments:
- Free zones: Companies operating in designated free zones (e.g., Rijeka, Split, Osijek, Vukovar) may benefit from 0% CIT for the first 5 years on profits derived from activities in the zone, followed by reduced rates in subsequent years
- Investment incentive: 50% CIT relief for 10 years on eligible investment projects exceeding EUR 3 million in fixed assets and creating at least 15 new jobs
- Labour incentives: Reduced social security contributions for newly employed workers in certain regions (up to 5 years)
- R&D incentive: 200% super-deduction for qualifying research and development expenditure (i.e., double deduction from taxable income)
These incentives are part of Croatia's strategy to attract foreign direct investment and stimulate economic growth in less developed regions. The free zone in Vukovar is particularly generous due to the city's post-war reconstruction status.
Taxable Income and Deductions
Corporate taxable income is determined by adjusting accounting profit for tax purposes. Key deductions include: business expenses fully and exclusively incurred for business purposes, depreciation of fixed assets (rates vary by asset class — buildings 5%, equipment 10–25%, vehicles 25%, computers 50%), interest expenses (subject to thin capitalisation rules — debt-to-equity ratio of 4:1, with interest exceeding 30% of EBITDA restricted). Non-deductible expenses include: fines and penalties, entertainment expenses (50% deductible), donations exceeding 2% of revenue, and expenses not supported by proper documentation.
Withholding Taxes
Croatia imposes withholding tax on certain payments to non-residents: dividends 10% (0% to EU residents meeting conditions), interest 10% (0% to EU related parties), royalties 15% (reduced under DTTs, 0% to EU companies with qualifying ownership). Withholding tax rates may be reduced under Croatia's extensive network of over 65 double tax treaties. The standard WHT rates for non-treaty jurisdictions are 12% on dividends, 15% on interest, and 15% on royalties.
Filing and Compliance
The corporate tax year is the calendar year (unless a different fiscal year is approved). The annual CIT return is due by 30 April of the following year. Companies must make advance CIT payments quarterly during the tax year based on the prior year's tax liability. Monthly payments are required for large taxpayers. Transfer pricing documentation is required for transactions with related parties exceeding certain thresholds (EUR 750,000 for goods, EUR 200,000 for services, EUR 100,000 for royalties). Penalties for late filing range from EUR 1,000 to EUR 500,000 depending on the severity of the violation.
