On 20 August 2026, the Finnish Tax Administration updated its guidance on the taxation of employee stock options (työsuhdeoptio) and employment-related share awards (osakeannit) in international situations. The guidance addresses the allocation of taxing rights between Finland and other jurisdictions under applicable double tax treaties (primarily following the OECD Model Tax Convention Article 15) and the Finnish Income Tax Act. It covers scenarios where an employee receives equity compensation from a Finnish employer while working partly abroad, or from a foreign employer while working in Finland, including the treatment of vesting periods, exercise events, and subsequent share sales. The update incorporates recent case law from the Finnish Supreme Administrative Court (Korkein hallinto-oikeus) and the OECD’s 2022 commentary updates on equity compensation.
Key Takeaways
- Source-State Taxation Based on Workdays: Finland taxes the portion of the equity gain attributable to workdays physically performed in Finland during the vesting period. The guidance provides a detailed day-count allocation formula and requires employers to maintain accurate travel records for mobile employees to support the allocation.
- Timing of Taxation: Grant vs. Exercise vs. Sale: For qualifying Finnish stock options (approved under Section 51a of the Income Tax Act), taxation is deferred until sale of the shares. For non-qualifying options and foreign plans, taxation generally occurs at exercise. The guidance clarifies the interaction with foreign tax credits and the application of the “economic employer” concept for seconded employees.
- Withholding and Reporting Obligations for Employers: Finnish employers (or Finnish economic employers) must withhold tax on the Finnish-source portion at exercise or vesting, report the income on the employee’s annual tax certificate, and submit detailed information returns (Form 6065) for cross-border equity awards, with penalties for non-compliance.
