How it works

Three rules shape the year.

  1. 1. A sale or a settlement

    Each closed position is one row: what you paid, what came back. A settlement counts as a sale.

  2. 2. Short or long term

    Held a year or less is short-term. Longer is long-term.

  3. 3. Losses

    A net loss can take up to $3,000 a year off other income. The rest carries forward.

Precedent, and arguments against.

Capital gains is how most investments are taxed. The arguments against it come from the other routes: that an event contract is a Section 1256 contract, a wager or a swap.

There is no IRS guidance for prediction markets, but all income must be reported. Realize explains the options so you can choose for yourself or with one of our licensed CPAs.

The same year, every route.

See this year beside gambling, ordinary income and Section 1256 before you choose.
