Income Optimisation for Freelancers and FIEs in Estonia

Yes — entirely and without qualification. Every strategy on this page is explicitly provided for under Estonian tax law. Using the basic exemption is legal. Making pension contributions is encouraged by the government. Switching to an OÜ and taking minimum salary plus dividends is the standard practice for owner-managed businesses in Estonia and is how the tax system was designed to work. Tax avoidance — using structures or arrangements that have no commercial purpose other than to avoid tax, often involving artificial transactions — is different and not what is described here. What is described here is tax planning: using available legal provisions to pay no more than you are required to.

At €28,000, the tax saving from an OÜ is approximately €5,000–6,000 per year. After accounting for typical OÜ accounting costs of €1,800–3,000, the net benefit is €2,000–4,200 annually. That is a meaningful but not enormous saving — and it comes with more administrative complexity (annual report, monthly payroll declarations, double-entry bookkeeping). The decision depends on your preferences: if you value simplicity and the tax saving feels marginal relative to the admin overhead, stay FIE. If you prefer to optimise financially and will work with a good accountant who handles the complexity, the switch makes financial sense. At €35,000+, the answer tilts more decisively toward OÜ.

The deductible limit for III pillar contributions is the lower of: 15% of your annual income for the year, or €6,000. For a FIE earning €50,000, 15% is €7,500 — so the €6,000 absolute cap applies. For a FIE earning €20,000, 15% is €3,000 — so the percentage cap is the binding limit. The deduction reduces your income tax base (not the social tax base), saving 20% of the contributed amount in income tax. Contributions made in calendar year 2024 are deductible on the 2024 Form A filed in April 2025.

An issued invoice creates a legal obligation for the client to pay. Under cash-basis FIE accounting, the income is recognised only when payment is received — so if the client pays in the next year, the income falls next year regardless of when the invoice was issued. You can legitimately negotiate a January payment date for a December invoice if the client agrees and if the payment timing is consistent with normal business practice for your relationship. What you cannot do is issue an invoice, receive payment in December, and then claim the income is January income — the date of actual cash receipt determines the year.

Switching mid-year creates a partial-year FIE income period (January to the switch date) and a partial-year OÜ period (switch date to December). For the FIE period, you file a normal (partial) income tax return by 30 April of the following year, paying social tax on the FIE income earned before the switch. From the OÜ period onward, the OÜ has its own filing obligations (payroll TSD by the 10th, VAT KMD by the 20th if registered, annual report by 30 June following the financial year). The cleanest implementation is always a January switch — but mid-year is workable with proper planning. Coordinate the transition with your accountant 6–8 weeks before the intended switch date.
