The flow

Three steps. Pay only at step three.

And only if you want filing‑ready files. The comparison is free either way.

Step 01 / 03

Paste your wallet.

Drop in your Polygon address. We read your CTF Exchange trades directly — no CSV uploads, no API keys, no signup.

The moat

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.

Worst case under OBBBA

Gambling income

$11,490

owed

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.

Capital gains

$4,287

owed

Each closed position is a sale of a capital asset. FIFO cost‑basis matching, short‑ vs. long‑term split, standard 8949 line items.

Net trading P&L on Schedule 1 line 8z. Used by some prediction‑market participants treating activity as a trade or business under §162.

Why us

Built different 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.

Pricing

Pay once per tax year. No subscription, ever.

Run the free comparator first — pay only when you've decided which framework you want files for.

FAQ

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.
