vs 60.7% through an agency employer
On €55,000 of invoiced revenue, a FIE (füüsilisest isikust ettevõtja, Estonia's sole proprietor status) keeps €34,104 (62.0%). The same revenue billed through an agency that employs you nets €33,398 (60.7%), before the agency takes any fee. The two routes land within about €700 of each other because both pay Estonia's 33% social tax. The only question is who writes the cheque.
The common mistake is to compare a FIE with an employee on the same headline figure. An Estonian payslip looks light (22% income tax and 1.6% unemployment insurance) because the employer pays the 33% social tax on top of the salary. When you bill through an agency, that employer cost comes out of your day rate before your salary is set. As a FIE, you pay it yourself, on a slightly smaller base, and deduct it before income tax.
Compare FIE and agency structures at your own day rate.
Open the contractor calculatorWhy the same 33% rate hits so differently
An agency-paid contractor is an employee of the agency. The agency owes 33% social tax and 0.8% employer unemployment insurance on top of your gross salary, as our employer social tax explainer describes, and it funds both from what the client pays. So €55,000 of billing supports a gross salary of about €41,106 (€55,000 ÷ 1.338). That salary then takes 1.6% unemployment insurance and 22% income tax on what is left above the €8,400 exemption.
A FIE invoices clients directly and pays the social tax personally. The Estonian Tax and Customs Board (EMTA) sets the FIE social tax base at business profit divided by 1.33, so on €55,000 of profit the base is about €41,353 and the social tax €13,647, roughly 24.8% of profit. That social tax is then deducted before the 22% income tax. The base has a floor of €886/month (€10,632/year for 2026), so a FIE with low profit still owes at least €3,508.56, and a ceiling of 15 times that floor.
FIE vs agency-employee, three day rates
All scenarios assume 220 billable days a year, no deductible business expenses and no agency fee, for a clean comparison of the structural tax difference alone. A real umbrella fee would lower the agency column further.
| Day rate | Revenue | FIE net | FIE % | Agency net | Agency % |
|---|---|---|---|---|---|
| €150/day | €33,000 | €21,201 | 64.2% | €20,778 | 63.0% |
| €250/day | €55,000 | €34,104 | 62.0% | €33,398 | 60.7% |
| €400/day | €88,000 | €53,457 | 60.7% | €52,328 | 59.5% |
Computed with PayMetric's own Estonia contractor calculator engine (both structures), 220 billable days/year, 2026 income tax and social tax rates. Agency figures assume the agency passes the whole rate through as salary plus employer taxes.
The €10,632/year minimum base catches low-profit FIEs off guard
If your FIE's actual profit for the year comes in below €10,632, you still owe social tax calculated on that floor, roughly €3,508.56, not a smaller amount proportional to your lower profit. A FIE earning only €5,000 in profit for the year, for example, effectively pays over 70% of that profit in social tax alone, a far higher effective rate than the flat 33% headline suggests.
This is where the agency route genuinely wins: in a thin year, an agency only pays social tax on what it actually pays you. It makes FIE status a poor fit for genuinely part-time, occasional, or early-stage self-employment where profit is likely to sit below the annual floor, budget for the minimum bill regardless of how the year actually goes.

Frequently asked questions
What is a FIE, and how is it different from a limited company?
FIE (füüsilisest isikust ettevõtja) is Estonia's sole proprietor status, a self-employed individual registered directly with the Estonian Business Register, trading and invoicing under their own name without forming a separate legal entity like an OÜ (Estonia's private limited company). It's the simplest way to freelance or contract in Estonia, but it comes with a materially different tax mechanic than either employment or an OÜ.
Does a FIE pay more tax than an agency-paid contractor at the same revenue?
No, slightly less. Both routes pay the 33% social tax, they just pay it differently. An agency that employs you has to fund its 33% social tax and 0.8% employer unemployment insurance out of the rate it bills, so only about 74.7% of the invoice becomes your gross salary. A FIE pays social tax on profit divided by 1.33, about 24.8% of profit, and then deducts that social tax before income tax. On €55,000 of revenue, the FIE keeps €34,104 (62.0%) and the agency route keeps €33,398 (60.7%), before any agency fee.
Is there a minimum social tax a FIE has to pay, even with low profit?
Yes. Social tax for a FIE is calculated on the higher of actual business profit or a statutory minimum monthly obligation base, €10,632/year for 2026, meaning a FIE owes at least €3,508.56 in social tax annually even if their actual profit is lower. This floor matters most for part-time freelancers, early-stage sole proprietors, or anyone whose FIE income is genuinely small, the effective tax rate on very low profit can look much higher than 33% once this minimum applies.
Does the flat 22% income tax rate work the same way for a FIE as for an employee?
Yes, the rate and the €8,400/year basic exemption (maksuvaba tulu) are the same. What differs is the base. An employee is taxed on gross salary minus their 1.6% unemployment insurance and II pillar contribution. A FIE is taxed on business profit (revenue minus deductible business expenses) minus the social tax paid on it. PayMetric's calculator applies both deductions.
So is becoming a FIE ever the better choice over agency-paid contracting?
On take-home alone, a FIE edges ahead: about 1.3 points of revenue at these rates before any agency fee, and more once a real umbrella fee comes off the agency side. The agency route buys other things: an employment contract, unemployment insurance cover, no minimum social tax bill in a thin year, and no bookkeeping. A FIE suits steady, full-year contracting with real deductible expenses. If your income is patchy, the €10,632 minimum base can make FIE the more expensive choice.
How does unemployment insurance apply differently under FIE status?
It doesn't apply to a FIE at all in the way it applies to an employee. An agency-paid contractor has the standard 1.6% employee unemployment insurance withheld, and the agency pays another 0.8% on top, exactly like a regular employee. A FIE, having no employer, pays neither. That saving is part of why a FIE comes out slightly ahead, but it also means a FIE has no Töötukassa unemployment insurance benefit to fall back on between contracts.
Can a FIE deduct business expenses the way an agency contractor can't?
Yes, this is one of FIE status's genuine advantages not captured in the headline retention percentages above, which assume zero business expenses for a clean comparison. A FIE can deduct real, documented business costs, equipment, software, home office proportion, professional services, from revenue before income tax applies, reducing the taxable base. An agency-paid contractor generally can't deduct personal business expenses the same way, since they're taxed as employment income. Because expenses cut both the social tax base and the income tax base, substantial genuine expenses widen the FIE's lead over the zero-expense comparison above. Model them through the calculator's FIE mode.
