Kalshi tax documents

Checked against Kalshi’s own pages on 2026-09-13.

This is a CFTC-regulated market rather than a sportsbook. There is often no tax form at all for your trading gains, and you are left to report them yourself.

What Kalshi issues

1
  • Form 1099-INT for interest paid by Kalshi
  • Form 1099-MISC for credits and rewards
  • Form 1099-B for crypto transfers
  • Form 1099-DA for digital asset reporting
  • No form on that list covers gains on event contracts themselves

Where to find it

1

The Account tab, under the Tax Info page. Some forms arrive by email instead.

How it reaches you

1

Kalshi delivers it in your account and by email.

The win/loss statement, which is not your tax form

1

A Profit and Loss statement, downloadable from Account, Tax Info, then a year. Kalshi computes it first-in first-out and includes fees and rebates. They say it is not tax advice, but stop short of saying it is not a tax document.

This is the document a session log is built from, and the one most often mistaken for a tax form. Per wager or per session, and why it changes your bill.

Worth knowing

  • Kalshi is a CFTC-regulated exchange, not a sportsbook, and lists no W-2G among its forms.
  • Kalshi never says that it does not report event-contract gains. We conclude this only because no such form is on its own published list, and that is weaker than a statement.
  • Some forms come by email from Zenwork, Kalshi’s tax form provider, so search your inbox for that name as well as for Kalshi.
  • Profit and loss data refreshes only on the first of each month, so a figure checked mid-month is out of date.

What we could not confirm

We could not confirm the date the form appears, the company name that appears on the form, the amounts that trigger a form or how many forms to expect from a page Kalshi publishes that we could read. We have left those out rather than guess.
