Wash Sale Rules and Covered Calls

The IRS wash sale rule prevents taxpayers from claiming a tax deduction on a security sold at a loss if a substantially identical security is purchased within 30 days before or after the sale. For covered call writers, this rule applies when you buy back a covered call at a loss and sell a new, substantially identical call within the 30-day window. The disallowed loss is added to the cost basis of the replacement call, deferring but not eliminating the loss. Understanding how wash sales apply to covered call rolling is essential for accurate tax reporting and strategic planning.

When you roll a covered call at a loss (buying back an existing call and selling a new one), the IRS may treat this as a wash sale if the new call is substantially identical to the old one. Options with different strike prices or expiration dates may or may not be considered substantially identical, which is a gray area in the tax code. The safest approach is to treat any option on the same underlying with similar terms as potentially triggering a wash sale and track the cost basis adjustments accordingly.

Key Insight

Understanding covered call wash sale is essential for optimizing your covered call strategy. The calculator above helps you quantify the impact and make data-driven decisions.

How to Calculate Returns

Maximum Profit
Max Profit = (Strike - Purchase Price + Premium) × 100 × Contracts
Where:
Strike = Call strike price
Purchase Price = Your cost basis per share
Premium = Premium received per share
Breakeven Price
Breakeven = Purchase Price - Premium
Where:
Purchase Price = Your stock cost basis
Premium = Premium received
Practical Example
Given
Stock
$100
Cost Basis
$98
Strike
$105
Premium
$3.50
Calculation Steps
  1. 1Premium income = $3.50 × 100 = $350 per contract
  2. 2This demonstrates the core principle of covered call wash sale
  3. 3Maximum profit = ($105 - $98 + $3.50) × 100 = $1,050
  4. 4Breakeven = $98 - $3.50 = $94.50
  5. 5Downside protection = $3.50 / $100 = 3.5%
  6. 6Annualized return = 10.71% × (365/30) = 130.3%
Result
This position generates $350 in immediate income with a maximum profit of $1,050 (10.71% return in 30 days). The breakeven at $94.50 provides 5.6% downside protection.
