Key things Denmark forex traders need to know
1. Who administers forex tax in Denmark
The Skattestyrelsen (SKAT) is the primary authority responsible for collecting forex and CFD capital-gains tax in Denmark. Filings are made annually on Arsopgorelsen (TastSelv) with the deadline falling on 1 May (employees) or 1 July (self-employed). All records — broker statements, trade ledgers, and proof of any foreign withholding — should be retained for the statutory minimum period (typically 5-7 years).
2. How forex is classified versus CFDs
Forex and CFD profits are kapitalindkomst. Many derivative instruments follow the lagerprincip under section 33A of the Kursgevinstloven, meaning unrealised gains and losses are taxed annually.
3. Spread betting status in Denmark
Spread betting is not offered to Danish retail clients. SKAT would treat any such product as kapitalindkomst under the lagerprincip rather than as lotteriindtaegt.
4. Cryptocurrency treatment
Cryptocurrency gains follow personal income rules (statsskattelovens section 4-5) — gains are taxed as personal income (up to ~52% marginal) while losses are deductible only at ~25-27% effective, making crypto less favourable than FX/CFD.
5. Professional-trader reclassification
Denmark does not formally distinguish retail versus professional FX traders — the lagerprincip applies regardless. Business-scale activity may shift to personlig erhverv with self-employment social contributions.
