Estonia accounting compliance requirements

Estonia combines an e-Residency programme that lets founders manage an Estonian company entirely online through the Estonian Tax and Customs Board (EMTA) e-Tax portal with a distinctive corporate tax rule under which retained and reinvested company profits are taxed at 0 percent, with tax due only when profits are distributed.

0% tax on retained profits

Estonian companies pay no corporate income tax on profits kept and reinvested in the business, with tax charged only at distribution.

e-Residency digital filing

e-Residents use a government-issued digital ID to sign documents and manage their Estonian company's filings through the EMTA e-Tax portal without needing local tax residency.
