Covered calls have two tax consequences that a payoff diagram will never show you, and both are invisible until they have already happened.

One can convert a long-term gain into a short-term one. The other can strip the preferential rate off dividends you were counting on. Neither is exotic — both arrive from writing a strike that felt perfectly reasonable.

Qualified and unqualified covered calls

The tax code distinguishes a qualified covered call from an unqualified one, and the consequences differ substantially. Broadly, a call is qualified when it has more than 30 days to expiration and is not too deep in the money relative to the stock price.

The precise depth threshold moves with the share price and there are published tables for it. The practical shape is the part worth remembering.

Note the last row. A perfectly ordinary out-of-the-money weekly can be unqualified purely because of its duration, which is not something most people writing weeklies have considered.

Trap one: your holding period stops

Writing an unqualified covered call suspends the holding period on the underlying shares for as long as the call is open.

If you have held shares for eleven months and are a month from long-term treatment, writing a deep in-the-money call pauses that clock. The month passes and you are still short-term — and if you then sell, the gain is taxed at ordinary rates rather than the preferential long-term rate.

On a large unrealised gain that difference is substantial, and it is entirely avoidable by writing a qualified call instead.

Trap three: the timing of a sale you did not choose

Less technical but often more expensive in practice. Being called away is a sale, and it happens on the market's schedule rather than yours.

Shares with a large unrealised gain, held eleven months, called away in month twelve: you have realised a short-term gain you would have made long-term by waiting a few weeks. The covered call was profitable and the after-tax outcome may still be worse than not writing it.

This is why covered calls versus holding looks different in a taxable account than in an IRA, and why the strategy fits low-basis positions particularly badly.

Staying out of trouble

Write more than 30 days out. The simplest single rule, and it aligns with the 30-45 day convention this course recommends anyway for decay reasons.

Do not write deep in the money. Also good practice for non-tax reasons — there is almost no extrinsic value to collect down there.

Check the ex-dividend date. Relevant for both the qualified dividend rule and for early assignment.

Watch positions approaching a year. If shares are eleven months old with a large gain, that is the moment to be careful about which call you write.

Consider running it in an IRA. Every trap on this page disappears there, which is a large part of why so many wheels live in retirement accounts. See options in an IRA.

What can go wrong

Writing weeklies on a long-term position. Under 30 days is unqualified, and the holding period suspension is silent.

Writing deep ITM calls to “collect more premium”. Almost all intrinsic, and unqualified.

Adding covered calls to a dividend portfolio without checking. The classic way to lose the qualified dividend rate.

Ignoring the calendar on low-basis shares. Being called away at month eleven is an expensive way to be right.
