Croatian d.o.o. + crypto trading: the 2026 playbook

The corporate profit tax rate is 10% if revenues in the tax period are up to €1,000,000, and 18% if revenues exceed that threshold.

The taxpayer is a company or other legal or natural person resident in Croatia that performs an economic activity independently, permanently, and in order to gain profit, income, revenue, or other economically assessable benefits. The taxpayer submits a corporate (profit) tax return — the PD form — for the taxation period and pays corporate profit tax no later than four months following the end of the taxation period.

Even at the corporate level, rigorous transaction-level record-keeping is required. The Croatian Tax Authority's guidance on crypto (an individual ruling from Porezna uprava) is explicit on method:

In order to accurately determine the realised capital gain and correctly calculate the tax, the taxpayer must keep records of each purchased and sold financial asset according to the FIFO method (method of consecutive prices). Exceptionally, if multiple smaller transactions in the same asset are executed on the same day, aggregated daily data may be kept. Porezna uprava, čl. 70. st. 5. Zakona

This applies a fortiori to a company: every trade — buy, sell, swap — must be documented with price, date, and counterparty or exchange reference.

The 10% corporate rate is only on company profit. When you extract profits as a shareholder, withholding tax (porez po odbitku) applies: withholding tax on dividends and profit shares paid to non-residents is 10%.

So the effective total tax chain for a small Croatian d.o.o. distributing profits to an Austrian shareholder is:

before any Austrian residual tax obligations and double-tax treaty offsets

The Croatia–Austria Double Taxation Treaty may reduce the withholding further — confirm with a licensed tax advisor before relying on it.

This is critical. If your d.o.o. only trades crypto for its own account (proprietary trading), you are generally not a Crypto-Asset Service Provider (CASP) under MiCA and do not need HANFA authorisation. However, if you provide services to clients (exchange, custody, brokerage), the picture changes entirely.

• On 30 December 2024, Regulation (EU) 2023/1114 (MiCA) became applicable in Croatia, introducing uniform rules for the business and supervision of trading in crypto-assets and the provision of crypto-asset services throughout the EU.
• A Croatian company wishing to provide crypto-services must obtain prior approval from HANFA.
• Existing Virtual Asset Service Providers (VASPs) operating before MiCA must obtain HANFA authorisation by 1 July 2026 at the latest.

DAC8 provides for automatic exchange of information on crypto-assets between EU countries; its rules enter into force on 1 January 2026, expanding tax transparency to crypto-asset transactions.

Reporting Crypto-Asset Service Providers must start collecting data on reportable crypto-asset transactions of all EU-resident users from 1 January 2026, with the first reporting due between 1 January and 30 September 2027.

Incorporating in Croatia does not automatically shift your tax residency or remove Austrian obligations. Three risks deserve specific attention.

• Substance requirement. A Croatian d.o.o. must have genuine economic substance in Croatia (real management, decisions made there). If you sit in Vienna and "control" the Croatian company remotely, Austrian tax authorities may claim the company is effectively managed in Austria and tax it there under Austrian law.
• Austrian CFC rules / Wegzugsbesteuerung. Austria has controlled foreign-corporation rules. A shell Croatian company without substance could be re-attributed to Austria.
• Personal tax residency. If you remain an Austrian resident individual, Austria taxes your worldwide income — including dividends from Croatia — with credit for the Croatian withholding under the DTA.
