Recap has a comprehensive integration with Poloniex that makes it easy to manage your crypto tax calculations. Connect your Poloniex account to Recap to import your full history and automate your taxes. From 2026, tax authorities are widening the automatic reporting of crypto under frameworks such as the OECD's Cryptoasset Reporting Framework (CARF), so keeping an accurate record matters more than ever.

Why Poloniex tax can be difficult to calculate manually
Poloniex is one of the longer-running exchanges and it has always leaned towards active, altcoin-heavy trading. That is exactly what makes its tax position hard to pin down by hand. A few things tend to trip people up:
- A deep, long history. Accounts can go back many years across a wide range of assets, and every disposal is measured against a cost-basis pool built from that entire record.
- Heavy crypto-to-crypto trading. Poloniex is built around coin-for-coin pairs, and each of those trades is a disposal even though no ordinary money changes hands.
- Staking and earn rewards. Rewards are generally treated as income, valued at the moment you receive each one, and they arrive as a steady drip that is easy to overlook.
- Old and delisted assets. A long-standing account can hold coins that were later delisted or renamed, which makes an accurate cost history harder to rebuild from exports by hand.
How to import your Poloniex data into Recap
Connect your Poloniex account to Recap by API and we import your full history automatically, including trades, staking and earn rewards, deposits and withdrawals, however far back your account goes. Recap classifies and values every entry with our fair-market valuation engine and applies the tax rules for your jurisdiction, separating what is income from what is a capital gain.
Auto Sync with Poloniex How are Poloniex transactions taxed?
Tax treatment depends on the transaction type and where you are tax resident. Here is how the main Poloniex activities are generally treated:
| Transaction type | CGT disposal | CGT acquisition | Income |
|---|---|---|---|
| Deposits | CGT disposal: no | CGT acquisition: no | Income: no |
| Withdrawals | CGT disposal: no. The withdrawal itself creates no capital gains event, but Recap records any withdrawal fee paid in crypto as a disposal of the fee asset. | CGT acquisition: no | Income: no |
| Buying crypto with fiat | CGT disposal: no. The fiat leg is not a chargeable asset in Recap, so spending fiat is not treated as a disposal. If the trade fee is charged in crypto, Recap records that fee as a disposal of the fee asset. | CGT acquisition: yes. The bought crypto enters your Section 104 pool at the trade value. Recap's default: the fee is treated as an allowable cost on the acquisition and also emitted as a separate fee disposal. Configurable: turning on 'deduct trade fees' nets a same-asset fee off the acquired amount instead. | Income: no |
| Crypto to crypto | CGT disposal: yes. Disposal of the crypto sold, plus a separate disposal of any crypto paid as a trade fee. Recap's default: the trade is valued from the quote side (for portfolios created after 25 May 2022). Configurable: the HMRC trade valuation method can be switched to value from the disposed side. | CGT acquisition: yes. The crypto bought enters your Section 104 pool at the same trade value. Poloniex Convert/Swap legs arrive as two unlinked account-activity entries, so Recap pairs them into a single trade only when the match is unambiguous; an unpaired leg is recorded as a standalone acquisition or disposal instead, and a standalone acquisition enters the pool at zero cost. | Income: no |
| Selling crypto for fiat | CGT disposal: yes. Disposal of the crypto sold at the trade value, plus a separate disposal of any crypto paid as a trade fee. | CGT acquisition: no. The fiat received is recorded but fiat is never a chargeable asset in Recap, so no pool acquisition arises. Note that Poloniex settles most pairs in stablecoins such as USDT, which Recap treats as crypto, so those trades are handled as crypto-to-crypto. | Income: no |
| Staking and earn rewards | CGT disposal: no | CGT acquisition: yes. The reward also enters your Section 104 pool at the same market value used for the income figure. | Income: yes. Poloniex STAKING account activity is recorded as a staking reward and Earn interest records as income, both valued at market value on receipt. Recap's default: fees are not deducted from the income amount. Configurable: 'deduct income fees' nets a same-asset fee off the income figure instead. Separately, Poloniex airdrop, commission-rebate and referral-rebate activity is recorded as an airdrop (a pool acquisition with no income event), and legacy Poloniex margin-lending earnings are recorded as margin gains rather than income. |
| Transferring between your own accounts | CGT disposal: no. Moving crypto between your own Poloniex accounts or sub-accounts is not treated as a disposal. Any fee paid in crypto is recorded as a disposal of the fee asset; Poloniex account and sub-account transfers are imported with a zero fee. | CGT acquisition: no | Income: no |
This table shows how Recap classifies each transaction type by default. Some treatments — such as the acquisition cost used for airdrops — are configurable in Recap. This is general information, not tax advice; consult a qualified tax professional about your circumstances.
This table shows Recap's default classification for common Poloniex transactions. It is not an exhaustive schedule or a ruling. Treatment depends on your circumstances and jurisdiction, and you can recategorise any transaction where yours differ. Confirm your position with a qualified tax adviser.
Selling crypto for fiat is a disposal for capital gains purposes, and swapping one crypto asset for another is both a disposal of the coin you part with and an acquisition of the coin you receive, each measured against your cost-basis pool. Staking and earn rewards are generally treated as income at the value you receive them, and that same value enters your cost-basis pool, so only later growth is a gain. Transfers between your own accounts are not disposals.

What's in your Poloniex tax report
Recap turns your full Poloniex history into a single tax report: capital gains, losses and income worked out under the rules for your jurisdiction, high-volume and crypto-to-crypto trading pooled correctly, staking and earn rewards valued on the day they arrived, and a clear year-by-year summary you can file yourself or hand straight to your accountant.
Common Poloniex tax challenges and how Recap solves them
Poloniex accounts produce a few recurring tax problems, especially older and active ones. Here is how Recap handles each one:
- A long, deep history. Years of activity across many assets are slow to reconstruct. Recap imports the whole record and pools every disposal into a single cost-basis position.
- Crypto-to-crypto trades. Coin-for-coin trades are disposals, not simple swaps. Recap calculates the gain or loss on each one automatically.
- Staking and earn rewards. Rewards land as many small income events. Recap values each one at the point you receive it, so none are missed.
- Delisted or renamed coins. Old assets can be hard to track by hand. Recap identifies and values them so your cost history stays accurate.
Why Poloniex users choose Recap
Poloniex users often choose Recap because a long-running, altcoin-heavy account carries a lot of tax to track: years of coin-for-coin trades, staking and earn rewards as income, and older assets on top. Rather than rebuilding all of that by hand, you can connect by API and see your gains, losses and income reconciled in one report, ready to file or share with your accountant.
