At Summ, our goal is to help users turn complex crypto transaction histories into clear, compliant tax reports. That's why we're announcing a new partnership with CoinRabbit, a crypto asset management platform with loan, earn, trade and save services whose users often engage in on-chain activity that can carry tax implications.
If you use CoinRabbit to borrow against crypto, earn yield, or trade, those transactions have tax implications. Getting them into your tax report hasn't always been straightforward.
Summ and CoinRabbit have partnered to make that process simpler. CoinRabbit users can now import their transaction history into Summ via CSV and get it reflected accurately in their crypto tax report.
What this means in practice:
Import your wallets and exchanges, track on-chain and off-chain activity automatically, and generate a tax report you can hand to an accountant or file yourself. CoinRabbit transactions included.
Why this matters
Most crypto tax problems don't come from big trades. They come from gaps: missing transactions, untracked on-chain activity, cost basis that was never recorded. Lending, borrowing, and earning yield sit in that gap for a lot of people.
Summ is built to handle exactly this. It reconciles activity across 3,500+ wallets, exchanges, and blockchains, categorises transactions automatically, and calculates cost basis where it exists. Where data is incomplete, it surfaces that too, rather than hiding it behind a clean-looking number.
What our partnership means
Crypto activity including asset movements, interest, and on-chain interactions can trigger tax reporting obligations depending on local regulations. However, this activity is often spread across multiple wallets, exchanges, and blockchains, making accurate reporting difficult without the right tools.
Through this partnership, CoinRabbit users can use Summ's crypto tax reporting software to:
- Import wallets and exchanges
- Track on-chain and off-chain transactions
- Generate accurate crypto tax reports
This helps ensure crypto activity is fully captured and correctly reflected in tax filings.
Why accurate crypto tax reporting matters
Many crypto tax issues arise not from large trades, but from:
- Missing transactions
- Untracked on-chain activity
- Manual record-keeping errors
As DeFi, lending, and cross-chain activity become more common, using purpose-built crypto tax software is increasingly important for accurate reporting and compliance.
Summ is designed to support these use cases by automatically categorising transactions and calculating cost basis across thousands of data sources.
