We'll help you simplify your prediction market tax challenges.
Tracking hundreds of contract resolutions across Polymarket, Kalshi, and PredictIt is the part most accountants quietly hand back to you. We don't.
- ×Contract classification complexity - binary contracts, scalar markets, and on-chain resolutions each have different income vs. capital gains treatment.

Questions you may have about our prediction market tax accounting.
How are prediction market winnings taxed in Canada?
Canada treats prediction market activity as business income (100%) or capital gains (50% inclusion) depending on intent and frequency. We assess the facts of your activity and file it correctly with the CRA.
What about on-chain markets like Polymarket?
Every USDC deposit, contract buy/sell, and resolution is a potentially taxable event. We classify each one - income vs. capital, ordinary vs. business - and reconcile it against the on-chain record.
Do you work with both Kalshi and Polymarket traders?
Yes. Kalshi settles cash-based event contracts and Polymarket settles on-chain in USDC - the CRA treatment differs for each and we handle both correctly.
We're one of the few firms that understand prediction markets from a tax accounting perspective.
