For tax purposes, here are some of the main things to consider when dealing with worthless stock:
* Stocks that are considered worthless are deemed to have been sold on Dec 31 of the year in which it became worthless. This “sale” creates a short-term or long-term capital loss based on how long you have held the stock. The loss should be included in Schedule D of Form 1040 and treated like other capital gains and losses from the sale of securities in your portfolio for that year.
* A deduction for worthless stock needs to be taken in the year in which the stock becomes worthless. If the stock is deemed worthless in a year in which you already filed your tax return, you will need to amend your return for that year. Taxpayers have up to seven years to amend their tax returns to claim this deduction.
* If you take a loss deduction for worthless stock you need to prove to the IRS that the stock is really worthless. Obtaining documentation about when and if a stock is worthless can be difficult. However, the IRS generally accepts a 1099-DIV from the company or a letter from your broker that the company has been delisted and that the stock no longer has any value. If you do not receive any documentation from the company or your broker you may be able to hire a stock-tracing company to research the values for you and provide you with the necessary documentation.
Due to the complexity of these rules, it may make sense to consult with a tax professional if you have a substantial amount of holdings that you believe are worthless.
