# Crypto accounting

One workspace for transaction records, cost basis, and tax reports

**Crypto accounting** in Splits brings [transactions, token balances, tax lots, and reports](https://splits.org/docs/accounting) into one workspace. You can also [import an external address](https://splits.org/docs/accounting#imported-accounts) to include its history without moving funds to Splits.

## How it works

* **Review one transaction history.** [Accounting](https://splits.org/docs/accounting#transactions) combines inbound and outbound activity across the workspace. Filter by account, network, token, date, direction, or memo.
* **Track each acquisition.** [Lots](https://splits.org/docs/accounting#lots) record the quantity, acquisition date, and USD cost basis of tokens in each account. Splits matches disposals to lots using FIFO.
* **Preserve basis on internal moves.** A [transfer between workspace accounts](https://splits.org/docs/accounting#lots) carries its original basis and acquisition date into the receiving account.
* **Bring past activity into view.** [Imported accounts](https://splits.org/docs/accounting#imported-accounts) add external EVM address history. They grant **no signing authority** and do not become Splits accounts.
* **Correct source data.** [Edit or seed a lot](https://splits.org/docs/accounting#lots) when its price or acquisition date needs correction. The lot detail shows its correction history. Token quantity comes from indexed activity and cannot be edited.
* **Export records for your books.** [Reports](https://splits.org/docs/accounting#reports) include statements, transaction history, token balances, realized gains and losses, open lots, and a lot timeline. Give an accountant [read-only access](https://splits.org/docs/workspaces/roles#read-only-members) to review the workspace.

## Prepare your books

Prerequisites: create a [workspace](https://splits.org/docs/workspaces). An [Owner](https://splits.org/docs/workspaces/roles) must import external accounts.

:::steps
### Add the accounts you need

Use [Splits accounts](https://splits.org/docs/accounts) for current activity. To include an older address, use *Import account* on the [Imported tab](https://splits.org/docs/accounting#imported-accounts). Select its networks and an optional cutoff date.

### Review transactions and balances

Filter [Transactions](https://splits.org/docs/accounting#transactions) by period, account, and token. Compare the starting and ending balances. Review [hidden tokens](https://splits.org/docs/accounting/spam) if expected activity is absent.

### Review and correct lots

Open [Lots](https://splits.org/docs/accounting#lots) to inspect basis, disposals, and correction history. Seed pre-existing inventory or edit a price or acquisition date if the derived value is wrong. Recompute lots to refresh the results.

### Generate reports

Select a period and account scope in [Reports](https://splits.org/docs/accounting#reports). Generate a statement or export transaction history, token balances, gains, or lots for your accountant.

## Limits

* Accounting history is unavailable on [partially supported networks](https://splits.org/docs/introduction/networks-and-assets).
* A [lot warning](https://splits.org/docs/accounting#lots) can signal a balance difference or a correction that Splits could not apply. Review warnings before using the reports.
* Reports support bookkeeping and tax preparation. Splits does not categorize transactions into a P\&L or sync with accounting software yet. See the [cost basis deep dive](https://splits.org/blog/how-splits-tracks-cost-basis/).

## Programmatic access

Via the [Splits CLI / MCP](https://splits.org/docs/introduction/agents):

* `splits accounting lots list`: review tax lots (**Read** scope)
* `splits accounting imports create`: import an external address (**Write** scope and a user-bound API key)
* `splits accounting reports generate <report>`: generate a report (**Write** scope and a user-bound API key)
