The mechanics differ depending on whether the option expired, was closed, or was assigned — and on the surprising question of whether the thing underneath is an index or a fund that tracks one.
General information about how the rules are structured, not tax advice. Rules change, they interact with the rest of your situation, and the only reliable answer to a specific question is one from a professional who can see the whole picture.
A short option ends one of three ways, and each is handled differently.
This is the part that trips up first-timers looking at a broker's year-end summary and finding the premium apparently missing.
You sold a $50 put for $100 and were assigned. You bought 100 shares at $50, so $5,000 leaves the account — but your cost basis is $4,900, the strike less the premium.
Nothing is taxable yet. The premium shows up later, as a smaller gain or a larger loss, whenever you eventually sell the shares.
The mirror applies to covered calls. If the shares are called away, the premium is added to the proceeds rather than taxed separately, so you report a sale at strike plus premium. The holding period of the shares determines whether that gain is short or long term.
Both cases have the same practical implication: assignment defers the tax event and attaches it to the stock, so a year with a lot of assignments can show much less realized income than the premium collected would suggest.
Some contracts get an entirely different regime. Broad-based index options — SPX, NDX, RUT, options on VIX among others — are Section 1256 contracts, which brings two consequences:
The distinction that catches people: options on ETFs that track those indexes are not Section 1256. SPY, QQQ and IWM options are ordinary equity options, because an ETF is a security rather than an index. SPX and SPY track almost the same thing and are taxed under different regimes, and this is one of the larger practical differences between them.
The same split shows up in expiration mechanics, where index options are cash-settled and European-style while ETF options are neither.
The wash sale rule disallows a loss when substantially identical property is acquired within thirty days before or after the sale. It applies to options, and it crosses between options and the underlying stock, which is what makes it awkward in practice.
Realizing a loss on shares and then selling a put on the same company inside the window can trigger it. So can rolling a position in a way that reestablishes substantially the same exposure. A strategy that repeatedly closes and reopens positions on one underlying — which is a fair description of the wheel — generates a lot of opportunities for it.
The disallowed loss isn't lost; it's added to the basis of the replacement. But it moves income between years in ways that a premium-collected total won't show, and it's a common source of surprise on a 1099.
Writing calls that are deep in the money against stock you hold can suspend the holding period of those shares, which affects whether an eventual gain is long-term and whether dividends received during the period keep their qualified status. The rules define what counts as sufficiently out of the money for a call to be "qualified," and the thresholds depend on the stock price and the time to expiration.
Rarely relevant to someone writing calls a few strikes out. Very relevant to anyone writing deep in-the-money calls against a long-held low-basis position.
None of the above applies inside an IRA. No capital gains reporting, no wash sales to track, no basis adjustments. The constraint moves to what the account permits: uncovered writing is generally not allowed, and the cash-securing requirement is enforced by the account structure.
For a strategy built on cash-secured puts and covered calls, that's a natural fit, and it removes the entire subject of this article.
