About Cosmos Tax
A tax system of record for Cosmos Hub, not just another export tool.
Built for organizations, not just one wallet
Validator operators
Commission income substantiated per delegator, ready to hand to your accountant or auditor.
Institutional delegators
Self-custodied ATOM never gets you a broker-issued 1099-DA. This is the record you'd otherwise have to build yourself.
Retirement entities
Solo 401(k), IRA, and HSA staking income needs UBIT tracked separately. We compute the 990-T figures directly.
The compliance mindset
- Staking rewards are income when you receive them, not when you sell (dominion and control, Rev. Rul. 2023-14), the same way bank interest works.
- Cost basis is tracked wallet-by-wallet, not pooled across every address you own (Rev. Proc. 2024-28, effective 2025).
- We own the on-chain income side natively and publish exactly how; for capital gains across exchanges and other chains, export straight into your existing tax software rather than re-entering anything by hand.

The three tools
Reports
Paste one or more addresses and a date range, and get a full transaction history: staking rewards, transfers, IBC, fees, and Stargaze NFT trades, priced in USD with cost basis. Export it to Koinly, CoinTracker, and others, or download a filled IRS Form 8949, Schedule D, income report, or 990-T worksheet directly.
Generate a reportBalances
Holdings (liquid, staked, and unclaimed rewards) for any address, as of any date. These are pre-indexed daily snapshots, not a live node query, so a lookup is instant even for a wallet with years of history.
Look up a balanceAPI
Everything the Reports and Balances tools show you comes from the same public, documented, no-auth API. Pull events, balances, the ATOM price series, or the published pricing methodology directly into your own systems, rate-limited to 60 requests/minute.
