Key things Sweden forex traders need to know
1. Who administers forex tax in Sweden
The Skatteverket is the primary authority responsible for collecting forex and CFD capital-gains tax in Sweden. Filings are made annually on Inkomstdeklaration 1, section K4 with the deadline falling on 2 May of the following year. 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 kapitalinkomst (section of the Inkomstskattelagen covering all capital returns) taxed at a flat 30% rate reported on section K4 of the Inkomstdeklaration.
3. Spread betting status in Sweden
Spread betting is not offered to Swedish residents by ESMA-compliant brokers. Skatteverket would treat any such product as kapitalinkomst, not as lottery winnings under the spelskatt regime.
4. Cryptocurrency treatment
Crypto gains are also kapitalinkomst at 30%, but 100% of crypto losses are deductible (not the 70% applied to FX/CFD losses). Crypto disposals must be itemised on K4 section D.
5. Professional-trader reclassification
If trading is operated as an enskild firma or aktiebolag, profits become naringsverksamhet at progressive municipal plus state rates, together with social security contributions.
