The only tax tool built for Polymarket
See your Polymarket tax outcome under all three IRS frameworks.
Capital gains, gambling+OBBBA, and ordinary income — side-by-side, computed from your on-chain trades. Free preview. Pay $99 only when you want filing-ready forms.
Read-only · No signup · No wallet connect · Polygon address only
Sample wallet · 487 closed positions · 2026 tax year
How it works
Three steps. Pay only at step three, only if you want files.
Paste your wallet
Drop in your Polygon address. We read your CTF Exchange trades directly — no CSV uploads, no API keys, no signup.
See three answers
We run FIFO cost-basis matching, then compute your taxable income under capital gains, gambling+OBBBA, and ordinary income — side-by-side, free, in 60 seconds for most wallets.
Pay $99 for forms
Pick the framework that fits your facts. We generate IRS Form 8949 (PDF), Schedule D summary, and a TurboTax-importable CSV. Pay once. No subscription.
The IRS hasn't told you how to classify Polymarket trades.
So we show you all three answers.
Capital gains, gambling income, and ordinary income each produce a defensible filing position — and a different tax bill. Generic crypto-tax tools see your wallet as a string of token swaps. We see Yes shares, No shares, market resolutions, and redemptions — the way the IRS will read them. You pick the framework that fits your facts; we cite the published guidance behind each.
Capital gains (Form 8949)
Each closed position is a sale of a capital asset. FIFO cost-basis matching, short- vs. long-term split, standard 8949 line items.
IRS Pub. 550 · IRC §1221
Gambling income (§165(d))
Treat each market as a wager. Winnings flow to “Other income”; losses are deductible — but capped at 90% of winnings under OBBBA §70114, effective 2026. Break-even traders can owe five-figure phantom tax.
IRC §165(d) · OBBBA §70114 (eff. 2026)
Ordinary income (Schedule 1)
Net trading P&L on Schedule 1 line 8z. Used by some prediction-market participants treating activity as a trade or business under §162.
IRC §61 · §162 · Notice 2014-21 (analogue)
We don't take a position on which framework the IRS prefers. We show you all three and let you choose.
What you get when you pay
Standard tier — $99. Every file IRS-formatted, ready to attach to your return or hand to your CPA.
IRS Form 8949
Filing-ready PDF. Short-term and long-term sections, every closed position itemized with proceeds, basis, and gain/loss.
Schedule D summary
Net capital gain/loss totals, properly carried from your 8949 totals. Print and attach, or hand to your accountant.
TurboTax CSV
.txf-formatted import. Drop it into TurboTax Premier and your 8949 line items populate automatically.
Methodology PDF
Per-trade audit log: every cost-basis match, every framework calculation, every IRS citation. The page your CPA wishes other tax tools shipped.
Pro tier ($249) adds multi-wallet consolidation, amended-return workflow, and priority email support.
Built differently than generic crypto-tax tools.
Read-only, by design
We never ask you to sign or connect. We read public on-chain data — that's it. We can't move funds.
Methodology, not advice
Every framework's math links to the IRS publication or statute behind it. We tool, we don't opine.
No subscription
$99 one-time per tax year. We don't auto-renew, we don't email you about renewals, we don't exist after you close the tab.
Decodes Polymarket directly
We read CTF Exchange events natively — Yes/No shares, market resolutions, redemptions. Not a generic ERC-20 sniffer.

Questions before you paste a wallet
- Do you store my wallet data?
- Your wallet address is processed through our decoder; the resulting trade history is cached so you can re-open the comparator without re-decoding. We do not associate it with an email or identity unless you choose to pay (in which case we email your forms). No third-party analytics, no ads, no resale.
- Will the IRS accept Polymarket trades as capital gains?
- That's the open question — the IRS has not issued Polymarket-specific guidance. The capital gains framework reflects the position published by Camuso CPA and Green Trader Tax. Our role is to surface all three defensible positions and cite the source behind each, so you (or your CPA) can choose with full information. We don't give tax advice.
- What if I have trades on multiple wallets?
- The Pro tier ($249) consolidates positions across multiple Polygon addresses — useful if you split between a hot wallet, cold wallet, and a bot. Standard ($99) handles a single wallet at a time.
- What if I find an error in the output?
- Email us with the wallet address and tax year. We'll re-run the decode against the latest decoder logic and issue a corrected file at no additional cost.
- Why isn't this free end-to-end?
- The comparator is the work that decides your framework — that stays free. Generating filing-ready PDFs, the TurboTax-import file, and the per-trade methodology log is the work that goes on your return. That's $99.
- Can my CPA use these forms?
- Yes — they're standard IRS Form 8949 and Schedule D, plus a methodology PDF that cites every calculation. Most CPAs we've spoken with prefer this to a raw transaction CSV because the framework choice is already documented.
- What happens after January 2027?
- polymarket-tax updates annually for the new tax year. Your purchase is for one tax year; re-running for the following year is a separate $99 — the same way TurboTax works.
