Comparison of After‑Tax Outcomes of Option Writing Strategies: Covered Calls versus Cash‑Secured Puts

This paper examines the tax implications of covered call and cash‑secured put option writing strategies. Although both strategies are widely used to generate income, their tax consequences differ in timing and character of gains. The analysis shows that option premiums received by writers are generally taxed as short‑term capital gains, while exercise and assignment events affect either the sale proceeds of existing holdings or the cost basis of newly acquired shares. Using a simplified numerical illustration, the study demonstrates that when options expire worthless, both strategies produce equivalent after‑tax income. However, when options result in stock transactions, covered calls may accelerate the realization of capital gains on appreciated shares, whereas cash‑secured puts defer gain recognition by reducing the basis of acquired stock until eventual sale. These differences have meaningful implications for after‑tax performance and portfolio management. The paper highlights the importance of integrating tax considerations into option strategy selection and provides practical guidance for investors seeking to optimize after‑tax outcomes in taxable investment accounts.
