Suppose I buy one share of stock in AAPL.

6 months later I buy another share.

6 months later AAPL does a 2:1 reverse split and I sell the resulting share.

Would I pay short term or long term capital gains on that sale?

In the US you would split the sale back to 1/2 a share each and also halve the net amount received from the sale. Then, you'd pair them off.

So if the holding period is 6 months for the first purchase then it would be a short term gain (or loss) and the second purchase would be a long term gain (or loss).

It's the same process as when a stock does a traditional 2:1 stock split except it's now done in reverse (1:2).

  • Interesting. Everything I've read indicates that during a reverse split companies will cash you out instead of issue you partial shares. So if I have two tax lots I would end up with two fractional share lots that would both be cashed out? Or do I own a whole share and it's just split in half for tax calculation purposes?

    Fractional share result from stock splits, DRIP purchases, or other corporate actions. If a broker is not set up for maintaining fractional shares, you will receive a cash in lieu payment for them. So if you bought two shares (one share each on two ocasions) then with a 1:2 revese split, you'd end up with one share in your account. If if you bought three shares (one share each on three occasions) then with a 1:2 reverse split, you'd end up with one share in your account and cash for 1/2 a share. With a split, sometimes shareholders are given the cash in lieu option. Mar 1, 2020 at 14:21

Each transaction stands on its own. The reverse split changed your first 1 share into 1/2 share, and it changed your second 1 share into 1/2 share. In both cases, the basis didn't change -- you paid what you paid, and it's the excess over what you paid that gets taxed. And the holding period didn't change -- you bought it when you bought it. If you sell both 1/2 shares at the same time it doesn't change things; each 1/2 share is taxed based on when you bought it and your basis is the amount that you paid for it.

It might be easier to picture this with bigger numbers, so that you aren't dealing with half shares. If you bought ten shares and later bought another ten shares, the reverse split would leave you with a total of ten shares, five from the first purchase and five from the second. If you sell the first five shares you have a 1 year holding period, so a long-term capital gain. If you sell the second five shares you have a six month holding period, so a short-term capital gain. If you sell all ten shares at the same time you still, conceptually, have two sales: five shares with a long-term capital gain and five shares with a short-term capital gain.
