Taxes & IRS Reporting
This page is informational only and not tax advice. Prediction-market tax treatment can be complex, and users should avoid strong assumptions unless they are working from current platform documents and professional advice.
The practical takeaway is simple: keep records, check what your platform actually provides, and do not assume every event-contract platform is reported the same way.
Short answer
Prediction-market taxes depend on your jurisdiction, your platform, and how your activity is reported and classified.
Some platforms provide tax documents and profit-and-loss tools. Others may require much more manual record-keeping from the user.
What users should focus on
For most readers, the most important tasks are:
- tracking every trade, entry, exit, fee, and payout
- keeping platform documents and downloadable statements
- checking whether the platform provides formal tax forms
- consulting a tax professional for classification questions
Platform differences
Platform reporting can differ materially.
For example, Kalshi's tax information page says users who meet certain IRS reporting thresholds may receive forms including 1099-INT, 1099-MISC, 1099-B, and 1099-DA, and it says Kalshi cannot provide tax advice. That is useful, but it is still not a substitute for personal tax guidance.
Users should treat platform-specific tax pages as operational guidance, not as final tax law.
Why this topic is easy to get wrong
Tax mistakes often happen when users:
- rely on old forum posts or social posts
- assume one platform works like another
- fail to keep records until year-end
- confuse platform terminology with tax classification
Practical checklist
- download statements regularly
- keep CSV exports if available
- save records of deposits, withdrawals, trades, and fees
- flag unusual trades or disputed settlements for later review
FAQ
Does every platform issue the same tax forms?
No. Reporting can differ by platform and by user circumstances.
If a platform gives me a statement, is that enough?
It helps, but users are still responsible for filing accurately and for asking a tax professional when the classification question is unclear.
