Enterprise Architect Day Rate Calculator: Estonia 2026

Your tax treatment depends on your operating structure. Agency: paid through an agency/umbrella that runs your pay exactly like a permanent employee, a flat 22% income tax above the basic exemption plus 1.6% employee unemployment insurance. FIE (füüsilisest isikust ettevõtja, sole proprietor): a genuinely different mechanic, you pay the same 22% income tax on profit above the basic exemption, but also pay the 33% social tax directly, normally an employer-only cost for a regular employee, subject to a statutory minimum monthly base. The calculator above shows both side by side.

Retention rates vary by structure and day rate. Agency contractors typically retain more, since the 33% social tax that binds a FIE is normally an employer cost that never touches an employee's payslip. FIE contractors take on that 33% social tax themselves in exchange for greater control and no agency fee, and are also subject to a statutory minimum social-tax base even at low profit.

Agency generally nets more at most day rates, since the 33% social tax a FIE pays directly would otherwise be an invisible employer cost. FIE gives more control over invoicing and expenses and avoids an agency fee, and can make sense once your day rate comfortably clears the 33% social tax and the statutory minimum monthly base. Compare both structures at your actual rate in the calculator above.

At €389/day over 220 billable days, the gross annual contract income is €86K. This is a 38% gross premium over the Enterprise Architect permanent salary median of €62K/year. The premium compensates contractors for self-funded social tax (FIE), holiday pay, sick pay, and business overheads a permanent employer covers on an employee's behalf.
