5 Key Accounting Priorities for Estonian Startups

Clean accounting from day one matters for fundraising
Investors and their lawyers conduct accounting due diligence before any term sheet is signed. Missing records, unexplained transactions, or incorrect equity accounting discovered during due diligence can kill or delay a deal. Getting the accounting right from incorporation costs far less than fixing it under deal pressure.
Burn rate and runway are calculated from your accounts
Burn rate (monthly net cash outflow) and runway (months until cash runs out at current burn) are the most critical metrics for a pre-revenue or early-revenue startup. These numbers come directly from your accounting — they are only as accurate as the books behind them.
Equity events must be recorded correctly or they create tax problems
Share issuances, convertible notes, SAFE agreements, and ESOP grants each create specific accounting entries. Recording them incorrectly — or not recording them at all — creates discrepancies between the cap table and the balance sheet, which EMTA and investors both scrutinise.
Estonia’s 0% retained profit tax is a genuine advantage for reinvestment
An Estonian startup that generates revenue can retain and reinvest all profits with 0% corporate income tax. No annual profit tax bill reduces the cash available for growth. This is a structural advantage over UK Ltd (19% corporation tax) or German GmbH (29.5% combined) at the same revenue level.
R&D grants have specific accounting and reporting requirements
Enterprise Estonia (EAS) and Kredex grants, EU Horizon grants, and other public R&D funding have accounting requirements attached — expenditure must be tracked against the approved project budget, reported at specific intervals, and returned if conditions are not met. Grant accounting is a specialist area.

What accounting does an Estonian startup specifically need compared to a standard OÜ? The core monthly obligations are the same — bookkeeping, TSD, KMD, annual report. The startup-specific requirements are on top: equity event accounting (every investment round, ESOP grant, convertible note), investor reporting (monthly MRR, burn rate, P&L vs budget), grant tracking (if EAS or other public funding is received), and compliance with IFRS (which major investors typically require for Series A and above). This page covers all of these.

Section 1 — Accounting Requirements by Startup Stage

From pre-revenue to scaling — what you need at each phase

What Changes at Each Stage

Stage Typical Accounting Needs EMTA Obligations What Investors Need to See
Pre-revenue (Idea / MVP) Double-entry bookkeeping; share capital recorded; founder expense tracking; R&D cost capitalisation decision Annual report (nil or pre-revenue); no TSD if no employees; no KMD if not VAT-registered Cap table; share capital paid-in confirmation; clean accounting from day 1; no unexplained liabilities
Early revenue (Seed / Pre-seed) Monthly P&L; revenue recognition policy (IFRS 15); cost allocation; burn rate calculation; first customer invoice accounting Annual report; KMD if VAT-registered; TSD if paying employees or board members Monthly P&L; MRR or ARR calculation; gross margin; runway calculation; burn rate
Funded startup (Seed / Series A) IFRS-compliant accounts; equity event accounting (share issuance, convertible notes); ESOP tracking; investor reporting package Full accounting suite; possible audit requirement if thresholds exceeded; R&D grant reporting IFRS accounts; capitalisation table; ESOP schedule; quarterly management accounts; KPIs vs plan
Start with RTJ — switch to IFRS when raising Series A
For pre-seed and seed stage startups, preparing accounts under Estonian RTJ is simpler and cheaper. When approaching a Series A (typically €2M+), investors will request IFRS-compliant accounts. Switching from RTJ to IFRS requires restating prior periods — the earlier you set up proper double-entry accounting, the easier the restatement will be.

Section 2 — Share Capital and Equity Events

Recording share issuance, new investment rounds, and changes to the cap table

Share Capital Under Estonian Law

Seed Round — €200,000 investment, 500 new shares at €400/share (nominal €1/share)
DR Cash — Company Bank Account: €200,000
CR Share Capital (500 × €1): €500
CR Share Premium (500 × €399): €199,500
Instrument Balance Sheet Classification Journal Entry on Receipt On Conversion to Equity EMTA Note
Convertible note (with maturity date) Financial liability (IAS 32) DR Cash / CR Convertible Note Payable DR Convertible Note Payable / CR Share Capital + Share Premium Interest on note is deductible expense; conversion itself is not a taxable event
SAFE (no maturity, no repayment obligation) Equity-like (no financial liability if no redemption right) DR Cash / CR SAFE Equity Reserve DR SAFE Reserve / CR Share Capital + Share Premium EMTA may scrutinise if structured to avoid distribution tax; ensure genuine equity character

Section 3 — Employee Share Option Plans (ESOP)

How to structure, record, and report stock options for Estonian startups

ESOP Under Estonian Law and IFRS 2

ESOP Stage Accounting Entry EMTA Tax Treatment Action Required
Grant date (options issued) No entry — or disclose in notes only (grant does not create immediate obligation) No tax event for employee Record option details: grant date, exercise price, vesting schedule, number of options
Vesting period (monthly accrual under IFRS 2) DR Share-based Payment Expense / CR ESOP Equity Reserve (non-cash) No tax event during vesting Monthly P&L charge = (Grant-date FMV × options vesting) ÷ vesting months
ESOP Accounting — Developer Option Grant
Grant details: Options: 100,000 options at exercise price €0.10/share. Vesting: 12-month cliff, 36 months total. Grant-date FMV of share: €0.50. Grant-date FMV of option: €0.40. Total IFRS 2 expense: €40,000 over 36 months = €1,111/month.
At exercise (employee buys 100,000 shares at €0.10 when FMV = €2.00):
Taxable income: 100,000 × (€2.00 − €0.10) = €190,000
Income tax (20%): €38,000 | Social tax (33%): €62,700

Section 4 — R&D Grants and Public Funding

EAS, Kredex, EU Horizon — how to account for public funding correctly

Frequently Asked Questions

A seed investment in exchange for equity is recorded as an increase to share capital and share premium — not as revenue. The exact entries depend on the transaction structure. Most commonly: the investor buys newly issued shares in the OÜ at a negotiated price per share. If the OÜ has 10,000 existing shares with a nominal value of €1 each and issues 2,000 new shares at €150/share (total €300,000), the entries are: DR Cash €300,000 / CR Share Capital €2,000 (2,000 × €1 nominal) / CR Share Premium €298,000 (2,000 × €149 premium). The transaction must also be registered in the äriregister. Until registered, the shares are not legally created. In practice, the investment closes when both the legal registration and the accounting entries are complete. Your accountant and your lawyer should coordinate on the timing of the accounting entries to match the legal completion date.

Yes — reconstructing startup accounts is something we handle regularly. The reconstruction process: we obtain all bank statements for every account for every period, all investment documentation (term sheets, share purchase agreements, notarial deeds for share transfers), all invoices issued and received, all salary and board fee payment records, and any grants received. From this we rebuild the general ledger from the beginning, reconcile the equity structure to the cap table, and bring the accounts up to current date. We also file any outstanding annual reports with the Business Register. The cost depends on how many periods need reconstruction and how well the source documents are organised — typically €800–2,500 for a two-year reconstruction. This is always cheaper than having investors discover a mess during due diligence.

Most Estonian startups do not legally require an audit. Under the Audiitortegevuse seadus (Auditing Activities Act), a statutory audit is mandatory for companies that exceed two of the following three criteria: total assets over €4.4 million; revenue over €8.8 million; average employees over 100. Below these thresholds, audit is voluntary. However, many investors — particularly institutional VCs and US-based funds — require audited accounts as a condition of investment at Series A and above, regardless of legal requirement. Enterprise Estonia and EU grants above certain amounts also require audit. Our recommendation: do not audit until an investor or grant requires it (saves €5,000–15,000/year for early-stage companies), but maintain IFRS-quality accounts so that when an audit is required, the accounts are clean enough to audit efficiently.

Under IFRS 2, options granted to advisors (who provide services) are treated the same as employee options — expense the fair value of options at grant date over the vesting period. The monthly P&L charge is: (Grant-date FMV of options) ÷ vesting months. If the advisor’s options have a grant-date fair value of €10,000 total (5% of company at the time), the monthly charge is €10,000 ÷ 24 = €417/month for 2 years. This creates a non-cash P&L expense of €417/month and a corresponding ESOP equity reserve on the balance sheet. At exercise, if the advisor buys shares at the exercise price, the gain (FMV at exercise minus exercise price) is treated as employment income subject to income tax and social tax — even though they are not an employee. EMTA views advisor options as equivalent to employee options for tax purposes.

EAS grants are not immediate revenue — they are conditional income that must be matched to the eligible expenditure period. On receipt of the €15,000: DR Cash €15,000 / CR Deferred Grant Income (liability) €15,000. As you incur the approved eligible expenditure: DR Deferred Grant Income / CR Grant Income (P&L) — matching the grant release to the expenditure period. For example, if €5,000 is approved for salaries and €10,000 for equipment, release €5,000 to income as the salary costs are incurred and €10,000 as the equipment is purchased. Maintain a project sub-ledger showing every euro of grant spending against the approved budget. EAS typically requires at least two interim reports and a final report with supporting invoices. If you spend the money on unapproved items or fail to submit reports, EAS can claim back the grant with interest — so the accounting and reporting discipline is commercially important, not just a formality.
