Accountancy services for OÜs in Estonia are not a collection of isolated services, but an annual cycle of obligations, where missing a deadline costs more than the work itself. Monthly returns, the annual accounts — which are mandatory even for companies that have not carried out any business activity — tracking payments to payment providers, ensuring VAT is correctly applied to your sales model, and decisions on dividends based on the financial statements. The owner doesn’t need an ‘accountant’; they need this cycle to run without requiring their attention.
We manage the accounts of Estonian companies remotely and comprehensively: from source documents right through to the signed annual report filed with the Commercial Register. We deal specifically with the issues that typically cause problems for international companies – multi-currency transactions, Stripe reports, Paddle and Wise reports, reverse charge and OSS, payments to contractors in different countries, and the accounting of crypto-assets. We take on companies from previous accountants, including cases where the accounts are in disarray.

Obligations arise not from the first profit, but from the moment of registration. The minimum cycle is as follows:
A zero return is the most underestimated obligation. The Register issues a warning, then imposes a fine, notifies the tax authorities and, in the long term, may initiate proceedings to compulsorily dissolve the company. The logic that ‘the company wasn’t operating, so there’s nothing to report’ does not apply in Estonia.
Everyone knows about the zero tax rate on reinvested profits. But almost no one realises that the real challenge for an international company lies in VAT. Three things that most often lead to additional tax assessments:
Practical conclusion: the decision on VAT registration is not a formality, but a calculated choice. For a pure service exporter, registration is often unprofitable; for a company with significant purchases, the opposite is true. We will analyse both scenarios using your figures.
Companies often put off changing their accountant, believing that ‘moving’ their accounts is a disaster. In practice, the procedure is straightforward, and the main risk lies not in the transition itself, but in continuing to work with an accountant who is no longer up to the job. What to look for when choosing a new one is covered in a separate guide: how to choose an accountant in Estonia in 2026.
Invoices you have issued; suppliers’ invoices and receipts; statements for all bank accounts; reports from payment providers and marketplaces; contracts with clients, contractors and employees; details of payments to individuals; documents relating to loans and the acquisition of assets; customs and import documents, where applicable.
A practical rule that saves both money and stress: documents should be submitted regularly, rather than a week before the deadline. The two most costly habits are losing receipts and paying for personal expenses from the company’s account. The latter creates not only an accounting issue but also a tax issue: such payments may be classified as taxable.
The key difference between a working process and a non-working one is the clarification stage. An accountant who does not ask questions does not save you time, but merely postpones the problem until the annual report or audit.

The additional 2% corporate profit tax, which had been planned for 2026, has been cancelled; the increase in income tax to 24% has also been cancelled. For further details, see the separate articles: taxes for companies in Estonia in 2026 and corporation tax in Estonia in 2026.
We tailor the accounting system to the company’s actual operations, rather than to a generic template — this is precisely what determines whether the company will face queries from the bank and the tax authorities.
A separate and frequently requested task: a company has been operating for several years without proper accounting records; reports have not been submitted or have been submitted merely as a formality; the tax authority is issuing directives. The process works as follows: an audit of the current status based on the register and tax authority data; collection and restoration of source documents for the relevant periods; compilation of ledgers; preparation and submission of overdue reports; and, where necessary, correction of previously submitted tax returns. The cost depends on the number of periods and the condition of the documents, so the estimate is always tailored to the individual case — but the general rule is simple: the sooner you start, the cheaper it is.
Please provide the company’s registration number, its sector of activity and the approximate volume of documents per month. We will check the company’s status in the register, determine the scope of our responsibilities and propose a package with a fixed monthly fee within one working day.
