Crypto history can be difficult to follow when it spans several exchanges and wallets. A withdrawal in one account appears as a deposit in another. An asset you sold this year may have been bought years ago on an exchange you no longer use.
Before you file a return or take the figures to an accountant, you need to understand how those records fit together. Coinfig helps you bring them into one place, find gaps, and review the calculations.
Start with the transactions behind the totals
Take a withdrawal from an exchange and a deposit into your own wallet. Looking at only one account leaves part of the history missing. Having both sides helps you establish where the funds went and match the transfer.
Or consider a sale where the earlier purchase is missing from your import. Before you rely on the calculation, you need to find that purchase history. The amount received from the sale does not tell you, on its own, how much you made.
Record losses and fees accurately. Their tax treatment depends on the circumstances, so keep the supporting records available for review.
Find the gaps before relying on a report
Coinfig brings together records from supported exchanges, wallets, and CSV imports. It helps you match transfers, identify gaps, and review the calculations behind your reports.
As you review your history, check:
- Have you included exchanges you no longer use?
- Can you match deposits to withdrawals from your other accounts?
- Do you have the purchase history for assets you later sold?
Coinfig flags potential gaps in the records you import. It cannot identify every account you have ever used, so gathering your full history still matters.
Once you have worked through the gaps, you can export transaction schedules and reports with the workings behind the totals. Keep your original statements and supporting documents alongside them so you or your practitioner can check individual entries.
If a tax authority asks about a figure
If a tax authority questions a figure, review the transactions behind it and find the supporting statements. Discuss any uncertainty with your tax practitioner.
A qualified practitioner can help interpret a request, assess the tax treatment, and prepare a response using your records and Coinfig reports.
A report does not guarantee that a tax authority will accept a tax position. It helps you understand and support the figures you submit.
Where your records go
Coinfig is an independent calculation and reporting tool. We are not endorsed by any tax authority and do not file your tax return on your behalf.
See section 6 of our Privacy Notice for how we may share personal information.
You do not need to upload identity documents, and your ID and tax numbers are optional.
You can import CSV statements or connect exchanges using read-only API keys you create. You can also delete an individual source without closing your account.
Work through your history one source at a time
Gather your exchange statements and the wallet addresses you have used. Add them to Coinfig, review the gaps, and check the reports against your records. Keep a list of anything you cannot resolve, and take questions that need professional judgement to a tax practitioner.
You remain responsible for your filing obligations and deadlines. Getting your records together gives you time to investigate missing history and understand the figures before you file.
