Monthly Accounting for Small Estonian Businesses
Practical guide to monthly accounting for a small Estonian OÜ – what you are legally required to do, how to handle common transactions, when VAT registration becomes mandatory, and what a typical month looks like for a small service or retail business.
5 Key Things a Small Estonian OÜ Must Know About Accounting
The Raamatupidamise seadus (Accounting Act) requires every OÜ to maintain organised double-entry accounts from the date it is registered in the Business Register. You cannot wait until you start earning to set up accounting. The obligation starts on day one.
The majandusaasta aruanne must be filed with the Commercial Register within 6 months after the end of the financial year. 30 June applies where the financial year ends on 31 December., regardless of whether the company had any revenue, expenses, or activity. A company with no transactions still files a nil annual report.
VAT registration generally becomes mandatory when the relevant turnover whose place of supply is Estonia exceeds €40,000 from the beginning of the calendar year. It is not a rolling 12-month threshold. From that point, the 24% standard VAT rate applies to most sales, and you file a monthly KMD.
Under the Raamatupidamise seadus, every accounting entry must be supported by a source document. Cash purchases, fuel receipts, restaurant bills – each must have a dated receipt or invoice. Documents must be retained for 7 years from the end of the financial year.
An OÜ owner cannot simply transfer money from the company account to their personal account without tax consequences. Payments to an owner must have an appropriate legal and accounting basis, such as salary, management board remuneration, dividend, reimbursement, loan or repayment of a genuine liability.
What accounting does a small Estonian OÜ actually need? For a small business with low transaction volume, no employees, and turnover below €40,000: monthly bookkeeping (posting invoices and bank transactions), annual report preparation, and EMTA correspondence handling. Add KMD monthly filings once VAT-registered, and TSD once staff is hired. The legal minimum is organised accounts and an annual report – everything else triggers based on business activity.
Legal Obligations for a Small Estonian OÜ
The complete list of what you must do and when
Complete Obligation Reference
The obligations below apply to a standard Estonian OÜ. Not all apply to every company; read the ‘Applies When’ column carefully.
| Obligation | Applies When | Deadline | Consequence if Missed |
|---|---|---|---|
| Maintain double-entry accounts | Every OÜ | Ongoing; accounting records must be kept current and complete | EMTA can assess; director may be personally liable for missing records |
| Retain source documents (invoices, receipts, contracts) | Every OÜ | 7 years from end of financial year | Documents requested by EMTA cannot be produced; deductions disallowed |
| File annual report (majandusaasta aruanne) | Every OÜ, even if inactive | 30 June (or 6 months after financial year-end) | Deletion is possible after the registrar’s additional deadline is missed and at least three months have passed since the statutory filing deadline, subject to the other deletion conditions. |
| File KMD (VAT return) | VAT-registered OÜ | 20th of each following month | Statutory enforcement measures or penalties may apply for non-compliance; interest of 0.06% per day applies to overdue VAT. |
| File TSD (tulu- ja sotsiaalmaksu deklaratsioon) | When reportable payments, taxable benefits or other TSD-reportable transactions occur, including payroll, dividends and non-business expenses; social-tax minimum obligations may also require filing. | The 10th of each following month | 0.06%/day interest on unpaid social tax and income tax |
| Register employment in the Employment Register | Where registration is required | No later than the moment the person starts work | Statutory enforcement measures or penalties may apply. |
| File dividend TSD annex | When OÜ distributes dividends | The 10th of the month following distribution | 0.06%/day on unpaid 22/78 distribution tax |
| VAT registration (KM-R application) | When the relevant Estonia-place-of-supply turnover exceeds €40,000 from the beginning of the calendar year | Within three working days after the registration obligation arises | EMTA can back-assess VAT from the date the threshold was crossed |
What ‘Small Business’ Means in Estonian Context
Estonia has a defined category of micro-undertaking: at least two of the following three indicators do not exceed: total assets €450,000, annual income €900,000 and average employees 10. Micro-entities may prepare simplified annual reports and are exempt from certain disclosure requirements.
However, micro-entity status only affects the format of the annual report. It does not change the core accounting obligations (double-entry bookkeeping, source documents, 7-year retention) or the EMTA filing obligations (TSD, KMD) that are triggered by business activity.
| Category | Criteria (max 2 of 3 exceeded) | Annual Report Format | Key Simplification |
|---|---|---|---|
| Micro-entity (mikroettevõtja) | At least two of: assets ≤ €450,000; annual income ≤ €900,000; average employees ≤ 10 | Abridged annual accounts with the notes required for micro-undertakings | No management board report required; no cash flow statement |
| Small undertaking | At least two of the following three indicators do not exceed: total assets €7.5 million, annual income €15 million and average employees 50 | Abbreviated – reduced notes compared to full | An abridged annual report may be prepared; a cash flow statement and statement of changes in equity are not required under the abridged format. |
| Medium-sized undertaking | At least two of the following indicators do not exceed: total assets €25 million, annual income €50 million and average employees 250 | Standard full GAAP annual report | Full notes, management report, cash flow statement |
| Large undertaking / public-interest entity (suurettevõtja / avaliku huvi üksus) | Exceeds at least two of the medium-sized undertaking thresholds (total assets €25 million, annual income €50 million, average employees 250) | Full GAAP annual report with full notes and management report | Audit requirements depend on the statutory audit thresholds and specific public-interest-entity rules; being above the medium-sized undertaking thresholds is not by itself the sole universal audit test. |
Common Transactions and How to Handle Them
Sales, purchases, expenses, cash payments, and owner payments: the accounting and VAT treatment for each
Transaction Reference Table
The table below covers the most common transactions a small Estonian OÜ encounters. Each transaction has a specific accounting treatment, VAT treatment, and required source document. All references are to Estonian law and EMTA guidance.
| Transaction Type | Accounting Treatment | VAT Treatment | Record Needed |
|---|---|---|---|
| Sales invoice to Estonian B2B client | Revenue in month of supply | 24% VAT output (if VAT-registered) | Invoice containing the information required by the VAT Act; a signature is not generally required, and the customer’s VAT number is required only where applicable. |
| Sales invoice to Estonian consumer | Revenue in month of supply | 24% VAT output (if VAT-registered) | Invoice with amount; no VAT number needed for consumer |
| Sales to EU B2B client | Revenue in month of supply | For qualifying B2B services, the place of supply is generally the customer’s Member State and reverse charge applies; goods are subject to separate intra-Community supply rules. | Invoice + VIES verification of client VAT number |
| Sales to non-EU client | Recognise revenue when the applicable revenue recognition criteria are met | VAT treatment depends on the goods or services, customer status and place-of-supply or export rules | Invoice with the wording required for the actual VAT treatment; export evidence where zero-rating of exported goods is claimed |
| Purchase invoice from Estonian supplier (VAT) | Recognise an expense when the goods or services are consumed, or an asset where the recognition criteria are met; invoice receipt alone does not determine the expense period. | Input VAT may be deductible where the purchase is used for activities giving the right to deduction and the statutory VAT deduction conditions are met. | Original invoice with supplier’s VAT number and your company data |
| Cash purchase with receipt (e.g. hardware store) | Recognise an expense or asset according to the nature of the purchase and the applicable accrual accounting rules. | Deduct input VAT only if the statutory deduction conditions are met and the receipt meets VAT invoice requirements. | VAT invoice with the required supplier, purchaser and transaction details; a till receipt is sufficient only if it meets those requirements or a permitted simplified-invoice exception applies. |
| Bank transfer fees and interest | Finance expense | No VAT (banking services are exempt) | Bank statement showing fee |
| Owner draws salary from OÜ | Salary expense; social tax on top | No VAT on salary payments | Employment contract; TSD declaration confirming amounts |
| OÜ pays owner as board member (juhatuse liige) | Management fee expense; social tax on top | No VAT on board fee | Shareholders’ resolution (or supervisory board resolution where applicable); service agreement; TSD filed |
| Dividend distribution to shareholder | Distribution of retained earnings | Company-level income tax at 22/78 on the net distribution | Shareholders’ resolution based on approved annual accounts and distributable profit; applicable TSD Annex 7 / INF 1 reporting; proof of payment |
Sample Journal Entries for a Small Service OÜ
Below are the four most common journal entries for a small Estonian service OÜ – a consulting company with monthly invoices to Estonian clients, some purchased services, and an owner taking a board member fee.
Sales Invoice: €1,000 service + 24% VAT to Estonian B2B client
| Account | Debit (DR) | Credit (CR) |
|---|---|---|
| Accounts Receivable / Trade Debtors | €1,240.00 | |
| Revenue – Services | €1,000.00 | |
| VAT Payable – KMD | €240.00 |
* Invoice issued; €1,000 revenue recognised in month of supply; €240 VAT collected and payable to EMTA by 20th of following month. VAT rate is 24% since 1 July 2025.
Purchase Invoice: €500 + 24% VAT from Estonian supplier
| Account | Debit (DR) | Credit (CR) |
|---|---|---|
| Professional Services Expense | €500.00 | |
| VAT Receivable (input VAT reclaimable) | €120.00 | |
| Accounts Payable / Trade Creditors | €620.00 |
* Input VAT of €120 is reclaimable on KMD (reduces VAT payable to EMTA). Requires valid Estonian supplier invoice with supplier’s VAT number. Input VAT only reclaimable if OÜ is itself VAT-registered.
Board Member Fee (juhatuse liige tasustamine): €1,500 gross
| Account | Debit (DR) | Credit (CR) |
|---|---|---|
| Management Fee Expense (board fee; €1,500 gross; no basic exemption applied; no mandatory funded pension contribution) | €1,500.00 | |
| Employer Social Tax Expense (33%) | €495.00 | |
| Income Tax Withheld (22%; payable EMTA) | €330.00 | |
| Net payment to board member | €1,170.00 | |
| Social Tax Payable (EMTA) | €495.00 |
* Management board remuneration is reported on TSD but is not taxed identically to ordinary employment salary. Social tax generally applies, while unemployment insurance contributions generally do not apply. TSD filed by the 10th of the following month.
VAT: When You Need It and What It Means
The €40,000 threshold, mandatory registration, and what changes when you become VAT-registered
The €40,000 VAT Registration Threshold
The VAT registration obligation generally arises when the relevant turnover whose place of supply is Estonia exceeds €40,000 from the beginning of the calendar year. The threshold resets at the beginning of each calendar year; it is not calculated on a rolling 12-month basis. Once you cross it, you must apply for registration by filing the KM-R form with EMTA, typically within 3 business days of crossing the threshold.
Taxable turnover includes all sales of goods and services subject to VAT (including zero-rated EU exports) but excludes exempt supplies (insurance, financial services, healthcare). Sales to private individuals inside Estonia count. Sales to VAT-registered EU businesses (zero-rated reverse charge) count. Sales outside the EU do not count toward the threshold under standard rules.
VAT Threshold Monitoring – Rolling 12-Month Calculation Example: Freelance web designer OÜ
July 2023: €3,200 (Estonian B2B clients)
Aug–Dec 2023: €3,500/month × 5 = €17,500
Jan–Jun 2024: €3,800/month × 6 = €22,800
Rolling 12-month total at 30 June 2024:
Jul 2023 – Jun 2024: €3,200 + €17,500 + €22,800 = €43,500
Threshold of €40,000 crossed during May 2024
VAT registration application (KM-R) must be filed with EMTA before the month in which the €40,000 was exceeded
From registration date: charge 24% VAT on all taxable sales
First KMD due: 20th of the month following registration
* Monitor your rolling 12-month total monthly once you approach €30,000
* Voluntary registration available below threshold – useful for B2B businesses
* Voluntary registration allows input VAT reclaim on purchases
Before and After VAT Registration: What Changes
| Area | Before VAT Registration (KM-kohustuseta) | After VAT Registration (KM-kohustuslane) |
|---|---|---|
| Invoices to Estonian clients | Invoice without VAT line; no VAT charged | Add 24% VAT to net price; show VAT amount and your VAT number on invoice |
| Invoices to EU B2B clients | For general-rule B2B services, reverse charge may apply even without full Estonian VAT registration; supplies of goods follow separate rules. | For qualifying general-rule B2B services: reverse charge, EE VAT number, KMD and VD reporting; goods follow separate intra-Community supply rules. |
| Monthly EMTA filings | Generally no KMD without a VAT reporting obligation; limited VAT registration or an invoice incorrectly showing VAT can create a filing obligation. | KMD must be filed by 20th of each month; even nil returns |
| Purchase invoices with VAT | No input VAT reclaim – VAT is a cost | Input VAT on business purchases reclaimable; reduces KMD payable |
| Cash flow | Lower prices to customers (competitive for B2C) | Prices increase by VAT for B2C customers; B2B clients reclaim VAT anyway |
| Bookkeeping complexity | Simpler – no VAT accounts needed | VAT payable and VAT receivable accounts required; monthly reconciliation |
| EMTA reporting | Annual report filed with the Commercial Register; TSD and other tax filings may be required even without employees. | Monthly KMD to EMTA; annual report to the Commercial Register; TSD and other filings where required |
If all your clients are VAT-registered Estonian companies or EU businesses, registering for VAT voluntarily below the €40,000 threshold is often worthwhile. Your clients can reclaim the VAT you charge them (so it does not make you more expensive), and you get to reclaim input VAT on all your business purchases – office supplies, software subscriptions, equipment, accounting fees. For a small OÜ with €20,000 in annual expenses, the input VAT saving could be €4,800 per year (24% of €20,000).
Paying Yourself: Salary, Board Fee, and Dividends
The three ways to extract money from your Estonian OÜ and the tax implications of each
You Cannot Simply Transfer Money to Yourself
A common mistake made by small OÜ owners is treating the company’s bank account as their personal account – withdrawing money whenever needed without structuring the payment correctly. Under Estonian law, all transfers from the OÜ to its owner must be classified as either: employment salary, board member fee, loan (which must be repaid), or dividend distribution. Unstructured transfers are treated by EMTA as deemed distributions and taxed accordingly.
| Payment Method | Tax on OÜ | Take-Home for Owner | Best For | Notes |
|---|---|---|---|---|
| Salary (töötaja) | Social tax 33% + employer UI 0.8% on gross | Gross less employee UI where applicable, mandatory funded pension contributions where applicable, and 22% income tax calculated after allowable deductions and any applicable basic exemption. | Regular monthly income; builds pension II pillar | Employment contract required; TSD filed monthly by the 10th |
| Board member fee (juhatuse liige tasu) | Generally 33% social tax; no employer unemployment insurance contribution on board remuneration | Gross less any mandatory funded pension contribution and 22% income tax after allowable deductions and any applicable basic exemption; no employee unemployment insurance contribution | Flexible – can be one-off or monthly without employment contract | Shareholders’ or supervisory board resolution required; declare on TSD using the applicable board-remuneration payment type |
| Dividend distribution | Company-level income tax generally at 22/78 of the net dividend, equivalent to 22% of the total including tax | Net dividend received; no further personal income tax if Estonian resident | Tax-efficient for larger sums; no social tax | Shareholders’ resolution based on approved annual accounts and distributable profit; TSD Annex 7 and INF 1 reporting |
| Loan to owner | First check the statutory lending prohibition; a loan agreement does not make a prohibited loan lawful | Not available where the Commercial Code prohibits the loan | Only borrowers and transactions permitted by law | An OÜ may not lend to an individual shareholder holding more than 5% of its share capital, or to a management or supervisory board member or procurator. Prohibited loan transactions are void. |
Which Is Most Tax-Efficient for a Small OÜ Owner?
Owner Payment Comparison – Extracting €1,000 from the OÜ
Option 1: Salary of €1,000 gross
Employer social tax (33%): OÜ pays an extra €330 on top = €1,330 total OÜ cost
Employee income tax (22% on €1,000 − €700 exemption): 22% × €300 = €66
Employee UI (1.6%): €16
Owner receives: €1,000 − €66 − €16 = €918
OÜ total cost for owner to receive €918: €1,330
Option 2: Board member fee of €1,000 gross
Same tax treatment as salary above
Owner receives €918 | OÜ cost: €1,330
Option 3: Dividend of €1,000 net (gross dividend = €1,000 * 22/78 = €1,352.65)
Distribution tax: €1,250 × 28% = €352.56 paid by OÜ to EMTA
Owner receives: €1,000 net (no further personal income tax for an Estonian resident)
OÜ total cost for owner to receive €1,000: €1,352.56
Dividend more efficient: €1,352.56 OÜ cost vs €1,330 for salary
BUT: dividends require retained earnings (profits must exist to distribute)
Salary builds II pillar pension; dividend does not
Optimal strategy: minimum salary (to satisfy health insurance); rest as dividend
No social tax on dividend – key efficiency gain
In Estonia, access to the public health insurance scheme (Haigekassa) is linked to payment of social tax. To maintain health insurance cover, social tax must be paid on at least the minimum monthly salary (alampalk, which is €946 in 2026). If you pay yourself a board fee of €946/month, the social tax of €312.18 (33%) ensures your health insurance remains active. Owners who pay themselves only dividends and no salary may lose health insurance coverage unless they have another social tax-paying basis (e.g., another employment).
Section 5 – Record-Keeping for Small Businesses
What documents to keep, for how long, and in what format
The 7-Year Rule and What It Covers
The Raamatupidamise seadus requires all accounting documents to be retained for at least 7 years from the end of the financial year in which they were created. For a company with a 31 December year-end, a 2024 receipt must be kept until at least 31 December 2031. Source documents include not just invoices but also contracts, bank statements, payroll records, and any other documents that support an accounting entry.
| Document Type | Retention Period | Format Acceptable | Who Keeps It |
|---|---|---|---|
| Sales invoices issued | 7 years from financial year-end | Original or certified digital copy | OÜ – stored in accounting system or secure archive |
| Purchase invoices received | 7 years from financial year-end | Original paper or digital PDF/XML | OÜ – filed by date or supplier name |
| Bank statements | 7 years | Electronic export or printed statement | OÜ – typically available from bank portal for 5 years; export and save |
| Employment contracts | Duration of employment + 10 years | Original signed copy | OÜ – HR file |
| Payroll records (TSD declarations) | 7 years from filing date | Electronic record from EMTA e-Tax portal | EMTA keeps filed declarations; OÜ should keep own copy |
| Cash receipts (kassatšekid) | 7 years | Scan of original; photograph acceptable | OÜ – can use apps to photograph and store digitally |
| Lease and service contracts | Duration + 7 years | Original or certified copy | OÜ – contract file |
| Annual reports filed | Permanently | Filed copy from e-Äriregister | Available in the Business Register permanently; keep your own copy |
Digital Document Storage, Fully Legal in Estonia
Estonia fully accepts digital document retention. The Raamatupidamise seadus allows accounting records to be kept in electronic form, provided the digital copies are legible, cannot be altered without detection, and are accessible throughout the retention period. A photographed receipt stored in Google Drive or Dropbox satisfies this requirement – provided the photo is clear enough to read all required fields (supplier name, date, amount, and VAT if applicable).
Take a photo of every receipt immediately. Blur or fade over time renders receipts unusable – photograph immediately.
Forward email invoices directly to your accounting email. Do not delete supplier invoice emails.
One shared folder organised by month/year. Each file named clearly: YYYYMM-Supplier-Amount.pdf
Always use your company LHV, SEB, or Swedbank card for business purchases – bank statement serves as secondary record.
