Accounting & Tax for Crypto and Web3 Companies in Estonia

No — not yet. Estonia’s corporate income tax applies only when profits are distributed, not when they are earned or when asset values increase. The unrealised gain on BTC held by your OÜ increases the company’s retained earnings and appears on the balance sheet (under the revaluation model as an equity reserve, or under the cost model as no balance sheet change until sold). If you sell the BTC, the realised gain increases retained earnings — still no tax. Tax arises only when the OÜ distributes dividends. At that point, the 20% distribution tax applies to the gross dividend amount. This structure allows crypto gains to compound and be reinvested indefinitely without triggering corporate income tax — one of the key reasons Estonian OÜs are popular for crypto treasury management.

Yes — swapping ETH for another token is a disposal of ETH at the current market price, which is a taxable event. At the moment of the swap, you have: (1) disposed of ETH at its EUR value at that time, creating a taxable gain or loss based on your ETH cost basis; and (2) acquired the new DeFi token at its current market value, which becomes the cost basis for the new token. Both events must be recorded. This is one of the most important and least understood aspects of DeFi taxation — routine interactions like swapping, providing liquidity, or harvesting yield can generate hundreds of individual taxable events per month for an active DeFi participant. For an Estonian OÜ, these gains are not taxed immediately — they accumulate in retained earnings and are taxed only when distributed. But they must still be recorded accurately.

Token issuance accounting depends entirely on the token’s classification. For a utility token (granting access to your platform’s services), the proceeds are typically deferred revenue — you have received payment for future service delivery. Revenue is recognised as the service is delivered. For a security token (granting equity-like rights, profit participation, or similar financial rights), the proceeds may be equity or a financial liability depending on the token’s terms. For a pure governance token with no clear economic rights, the treatment is the most uncertain — recent accounting committee discussions suggest it may be a financial liability if there are redemption features, or equity-like if it represents an ownership right. Before your TGE, engage an accounting expert to document the classification and treatment. The classification affects not only your balance sheet but also VAT treatment, EMTA tax obligations, and securities law compliance.

Staking rewards should be recorded as income at the time they are received, at the EUR fair market value at the time of receipt. In practice, recording each individual daily staking distribution would be extremely burdensome for most businesses. A reasonable practical approach — and one that most crypto accountants in Estonia use — is to aggregate staking rewards into weekly or monthly batches, using the average daily price for the period as the EUR conversion rate. The key requirements are: the quantity received must be accurate (from blockchain records), the EUR value must be based on market prices at or very close to the receipt date (not an estimated or delayed price), and the total must reconcile to your wallet balance at period-end. EMTA has not explicitly approved or prohibited this aggregation approach, but it is consistent with the principle of recording income in the period it arises.

It depends entirely on what your OÜ does. A VASP licence (now transitioning to MiCA CASP authorisation) is required if you provide services to other people — not for holding and managing your own crypto assets. Specifically, you need a licence if you: operate a crypto exchange or trading platform; provide crypto custody services (holding crypto on behalf of clients); transfer crypto on behalf of third parties; or offer other crypto asset services as defined in MiCA. If your OÜ is purely a personal or company crypto treasury — buying, holding, and eventually selling your own assets — you do not need a licence. If you are building a product or service where customers interact with crypto through your platform, almost certainly yes. The distinction between ‘managing our own treasury’ and ‘providing services to third parties’ is where the licensing requirement begins. When in doubt, seek legal advice from a fintech lawyer before launching — the penalties for operating without a required licence are significant.
