OÜ Accounting — Full-Service Bookkeeping for Estonian Private Limited Companies
Every Estonian OÜ is bound by the Accounting Act (Raamatupidamise seadus) and must file an annual report with the Business Register by 30 June following the financial year. What the law does not tell you is when outsourcing to a local accountant stops being optional. This page sets out the requirements an OÜ actually faces — and the decision framework we use with clients to choose between self-filing, a fractional engagement, and a full monthly service.
What the Accounting Act actually requires
Every OÜ must keep double-entry books, retain source documents for seven years, and file an annual report with the Business Register under the Accounting Act size classes (micro, small, medium, large). Micro and small entities file a reduced format. Late filing carries fines and, persistently, forced deletion from the register.
On top of the annual cycle, a VAT-registered OÜ files a monthly KMD by the 20th, and any OÜ with payroll files TSD by the 10th. The Tax and Customs Board (EMTA) issues penalties automatically, and repeat late filings hit the public tax-compliance rating counterparties see.
Do you need a local accountant?
Legally, no — the statute requires accounting, not an outsourced accountant. Practically, the answer moves with complexity. A dormant mikroettevõte with a handful of transactions can self-file through Merit Aktiva or the state e-arveldaja tool. Once VAT registration, payroll, intra-EU invoicing, or fintech activity enters the picture, the cost of a filing error with EMTA or the Financial Intelligence Unit (RAB) outgrows the monthly fee.
Our triage: dormant holding OÜ — self-file; operating OÜ with VAT or staff — standard package (€499); licensed or AML-obliged — compliance or fintech tier. We classify on the first call and give an honest recommendation, even when it means staying DIY for another quarter.
Tax and reporting cycle we handle
For an operating OÜ we close the books monthly, reconcile bank and card feeds, issue Peppol e-invoices for public-sector counterparties, file KMD and TSD, and prepare the annual report plus management narrative for the board. Dividends are taxed at 22% and we document the retained-earnings computation so any EMTA audit trail is defensible.
For clients importing stock, running Amazon FBA, or selling SaaS across the EU we map the VAT position before onboarding — OSS, IOSS, and standalone registrations each carry different cash-flow and compliance consequences. One contact person covers monthly accounting, annual report, and tax consultation — no handoff latency.
How much does OÜ accounting cost?
Our published packages are €499 for standard accounting, €1,500 for compliance-heavy clients, and €3,000 for fintech and AML-obliged entities; consultation is €150/hour. Tallinn market rates stretch from ~€100/month for a dormant mikroettevõte up to €5,000+ for a licensed EMI. Volume, regulatory load, and reporting complexity drive the fee.
We quote on transaction count, not headline revenue — that is what actually drives work inside our team, and it stops clean-books clients from subsidising messy ones. The proposal lists every filing in scope so competing quotes compare line-for-line.
Working with us
Onboarding takes two to three weeks: intake call, document transfer through our portal, chart-of-accounts alignment, and handover of prior working papers. We operate in English, Estonian, and Russian on the same ticket so founders, the Estonian board member, and the regulator each get their language without a translator step.
The team sits in Tallinn at Maakri 19/1; monthly closes are signed by a named Estonian-qualified accountant. If a question is outside our core coverage we say so and introduce the right specialist rather than stretching a retainer into unpriced territory.
