Estonia's corporate tax system is unlike anywhere else in the EU. The core principle: companies pay no corporate income tax on profits while those profits remain inside the company. Tax is triggered only by distributions — dividends, fringe benefits, gifts, non-business expenses, or deemed distributions like transfer pricing adjustments.
The rate in 2026: 22% on distributed profits, calculated as 22/78 of the net distribution. So if a company distributes €78 as a dividend, it pays €22 in corporate tax — the gross taxable amount is €100, the rate is 22/78. This rate was confirmed at 22% after a planned increase to 24% was cancelled by the Estonian Parliament in December 2025.
What triggers a taxable distribution:
- Dividend payments to shareholders
- Fringe benefits to employees or directors (company car, gifts, etc.)
- Non-business expenses paid by the company
- Transfer pricing adjustments
- Share buybacks or capital reductions
What does NOT trigger corporate tax:
- Revenue earned and kept in the company
- Reinvestment in assets, software, marketing, operations
- Paying market-rate salaries to employees or directors (salary triggers income and social taxes, not CIT)
The double taxation problem is real and frequently misunderstood. When the Estonian company pays corporate tax on a distribution, Estonia does not withhold any additional tax on the dividend paid to the shareholder. But the shareholder's home country almost certainly taxes that dividend as personal income. If you live in Germany and receive €78 from your Estonian OÜ after the company has paid €22 CIT, Germany may tax you on the full €78 at your marginal rate — with no credit for the €22 Estonia already paid (since that was paid at the company level, not withheld from you). The effective combined rate can easily reach 35–45%+ depending on your country. Estonia's 60+ double tax treaties reduce this in some cases, but don't eliminate it.
The founder who benefits most from Estonian OÜ tax treatment is someone who: doesn't need to distribute profits regularly, lives in a low-tax or territorial-tax country, or is building a company that will retain earnings for growth for several years before any exit or distribution.
Salary vs dividends. Many founders take a salary from their Estonian company, which is deductible at company level, and minimize dividends. Salary can trigger Estonian payroll taxes, but the result for a non-resident working outside Estonia depends on the work location, social-security coordination and the facts. Confirm this with a qualified adviser before setting payroll.
VAT registration is mandatory when annual turnover exceeds €40,000. The standard VAT rate has been 24% since July 1, 2025 (permanent increase from 22%). For B2B sales to EU clients, reverse charge applies and VAT is not collected. For B2C sales to EU consumers, the OSS scheme is relevant.
Key compliance obligations:
- Annual report filed with the Estonian Business Register within 6 months of the financial year end (mandatory even for dormant companies)
- Corporate tax declaration and payment — only when distributions occur; no annual CIT return needed if no distributions were made
- VAT declaration monthly if VAT-registered
- Maintain accounting records per Estonian Accounting Act
- Annual report must be submitted even if the company had no activity
Budget for an accountant. A dormant or very low-activity company can be maintained cheaply (€300–800/year including legal address and annual report). An active trading company without VAT typically runs €800–1,800/year. Active with VAT and any employees: €1,500–3,200/year. These are real costs and the accounting market in Estonia is competitive.
