Options are taxed according to the main rule in Chapter 10, Section 40 IL as capital income.
Options are taxed according to the main rule in Chapter 10, Section 40 IL as capital income. Each realization — purchase, sale, exercise or expiry — is a separate taxable event. This distinguishes options from stocks, where only a sale triggers taxation.
The most common misunderstanding is that exercising a call option is the same thing as buying the stock. Skatteverket considers, on the contrary, that the exercise is a realization of the option, followed by a separate purchase of the stock.
This means double taxation if you do not understand the chain.
Capital gain is calculated as sale price minus purchase price minus brokerage. Losses are deducted against gains in the same category. The year's net loss may be deducted up to 70% against capital gains, while the remaining 30% is carried forward.
For Swedish investors, brokerage and fees are deductible as a cost of the acquisition. If you buy an option for 5 kr and pay 0,50 kr in brokerage, your acquisition cost becomes 5,50 kr. On a sale for 8 kr with 0,50 kr brokerage, the profit becomes 8 - 0,50 - 5,50 = 2 kr.
Expired options count as a realization at 0 kr. If you bought a call option for 3 kr that expires worthless, your loss becomes 3 kr. This loss is deducted against other capital gains in the same year.
