How are proceeds from writing covered calls taxed?
The tax comes when you close the position. If the option expires worthless it's as if you bought it back for $0. There's a short-term capital gain for the difference between your short-sale price and your buyback price on the option. I believe the capital gain is always short-term because short sales are treated as short-term even if you hold them open more than one year. If the option is exercised (calling away your stock) then you add the premium to your sale price on the stock and then compute the capital gain. So in this case you can end up treating the premium as a long-term capital gain.
