How Are Covered Calls Taxed?

Covered call taxation in the United States depends on three things: what happens to the option (expires, is exercised, or is closed), the type of covered call written (qualified or unqualified), and your stock's holding period. The IRS treats option premium income differently in each scenario, and understanding these rules can save you significant money and prevent unexpected tax bills.

The most important rule to understand is that option premiums from covered calls are generally treated as short-term capital gains, which are taxed at your ordinary income tax rate (10-37% federal). This applies regardless of how long you have held the underlying stock. However, when shares are called away through exercise, the premium is added to the sale price of the stock, and the resulting capital gain may be long-term or short-term depending on your holding period.

Tax Formulas for Covered Calls

Tax on Expired/Closed Premium
Tax = Premium Income × (Federal Rate + State Rate + NIIT Rate)
Where:
Premium Income = Net premium received (after buy-back cost if closed)
Federal Rate = Your marginal federal tax bracket
State Rate = Your state income tax rate
NIIT Rate = 3.8% if AGI exceeds threshold
Tax When Shares Are Called Away
Capital Gain = (Strike Price + Premium - Purchase Price) × Shares
Where:
Strike Price = Price at which shares are sold
Premium = Premium received per share
Purchase Price = Your stock cost basis

Calculation Steps
  1. 1Total taxable options income = $12,000 + $5,000 = $17,000
  2. 2Federal tax = $17,000 × 24% = $4,080
  3. 3State tax = $17,000 × 5% = $850
  4. 4NIIT = $0 (not applicable)
  5. 5Total estimated tax = $4,080 + $850 = $4,930
  6. 6After-tax income = $17,000 - $4,930 = $12,070
  7. 7Effective tax rate = $4,930 / $17,000 = 29.0%
Result
On $17,000 of covered call income, you owe approximately $4,930 in taxes, leaving $12,070 after tax. Your effective tax rate on options income is 29.0%.

Qualified vs. Unqualified Covered Calls

The IRS distinguishes between qualified and unqualified covered calls. This matters because writing an unqualified covered call can suspend the holding period for long-term capital gains treatment on the underlying stock. A qualified covered call is one that meets specific criteria: the option must have more than 30 days to expiration and the strike price must not be too deep in-the-money (specific thresholds are defined in IRS Publication 550).

!
Critical Tax Rule

Writing an in-the-money call that does not meet the 'qualified covered call' definition can reset your holding period on the stock. If you held the stock for 11 months (nearly qualifying for long-term capital gains), an unqualified ITM covered call resets the clock to zero. This can cost you the difference between 15% and 37% tax rates.

Tax Optimization Strategies

How to Minimize Taxes on Covered Call Income

1
Use Tax-Advantaged Accounts
Write covered calls in a Roth IRA for tax-free premium income, or in a traditional IRA for tax-deferred income. This eliminates the short-term capital gains tax entirely.
2
Write Qualified Covered Calls Only
Stick to OTM or ATM calls with more than 30 days to expiration to avoid suspending your stock's holding period. Consult IRS Publication 550 for specific qualified covered call rules.
3
Harvest Losses to Offset Gains
If you have losing stock positions, you can sell them to generate capital losses that offset your covered call gains. Up to $3,000 in net losses can offset ordinary income per year.
4
Make Quarterly Estimated Tax Payments
If covered call income is significant, make quarterly estimated tax payments to avoid underpayment penalties. Use IRS Form 1040-ES to calculate payments.
5
Keep Detailed Records
Track every trade: date opened, date closed, premium received, stock cost basis, and whether the call was qualified. Your broker provides Form 1099-B, but maintaining your own records ensures accuracy.

Canadian Tax Treatment

In Canada, covered call premiums are generally treated as capital gains, with only 50% of the gain being taxable (the inclusion rate was increased to 66.67% for gains over $250,000 starting in 2024). Consult the CRA or a Canadian tax professional for current rules on options taxation in Canada.

Frequently Asked Questions

Covered call premiums are taxed as short-term capital gains, which are taxed at your ordinary income tax rate. This applies whether the option expires worthless, is bought back, or is held for any duration. The short-term treatment applies regardless of how long you have held the underlying stock.
