Taxation System and Optimization Opportunities

Corporate Income Tax (CIT)

Estonia’s revolutionary corporate tax system provides unparalleled opportunities for optimization:

Deferred Taxation Model: The cornerstone of Estonia’s system is no CIT on retained or reinvested profits. Tax is only due when profits are distributed through:

• Dividends to shareholders
• Non-business expenses and gifts
• Fringe benefits to employees
• Certain deemed distributions

Tax Rate: 22% on distributed profits (increased from 20% in 2025), calculated as 22/78 of the net distributed amount, resulting in an effective rate of approximately 25% on gross distributions.

Exceptional Optimization Opportunities:

Unlimited Profit Retention: Companies can reinvest profits tax-free indefinitely, maximizing growth potential and cash flow. This creates a significant competitive advantage for growth-stage businesses and startups.

Dividend Distribution Planning: Strategic timing of dividend payments allows companies to optimize tax efficiency based on business cycles and shareholder tax positions.

Holding Company Advantages: No withholding tax on dividends paid to EU/EEA companies makes Estonia ideal for holding company structures.

Group Relief: Estonian companies can benefit from group taxation rules, allowing efficient profit and loss allocation within corporate groups.
