Who asks for a source-of-funds proof in 2026?
It usually starts with a short email: “Please prove the origin of your cryptocurrencies.” From that moment, the clock is ticking. The list of institutions that ask has grown sharply with TFR, MiCA, and DAC-8.
Your bank
The most common trigger. After a larger crypto-to-fiat transfer, the bank runs an automatic review and, if in doubt, freezes the money until you can prove its origin.
The tax authority
Discrepancies between the exchanges’ DAC-8 reports and your own tax return trigger audits. The case officer then wants to see your source-of-funds proof.
The notary
As soon as part of the purchase price comes from crypto, the notary must verify its origin. Without proof, they can refuse to certify the deed.
Crypto exchanges
Enhanced compliance checks at onboarding or on large withdrawals require proof of where your holdings originally came from.
Private bank & OTC desk
Private-banking relationships (CH, LI, SG, UAE) and OTC desks often require documented proof of where your crypto wealth came from before they even open an account.
Lawyer & accountant
In an inheritance, divorce, business sale, or move abroad, the source-of-funds proof is often the central piece of evidence in the file.
The pattern is always the same: same question, same format, short deadline. A single, well-structured document covers all of these cases.
What is a crypto source-of-funds proof?
It answers a simple question: where do the coins behind this withdrawal come from? Instead of showing your whole portfolio or a list of trades, the source-of-funds proof traces each withdrawal back to its origin.
CoinTracking assigns every withdrawal to one or more of these five source types:
Fiat deposit
EUR wired to an exchange to buy crypto.
Crypto deposit
A transfer from a wallet you never imported, a gift, or an OTC purchase.
Mining & staking
Income from network participation.
Income & rewards
Airdrops, lending interest, or referral bonuses.
Other sources
Forks, recovered keys, and similar.
Not the same as a tax report. A tax report calculates gains and losses for a tax year. A source-of-funds proof answers a different question: where do the coins behind a specific withdrawal come from?

Why CoinTracking for your source-of-funds proof
The report is designed for exactly what compliance reviewers want to follow in just a few minutes.
Built audit-ready
The report follows the structure that banks, notaries, and tax authorities expect for a source-of-funds proof. Instead of loose receipts, the reviewer receives one complete, traceable document.
Generated in seconds
Instead of compiling transactions by hand, CoinTracking generates the complete source-of-funds proof as a PDF in a single click.
Sources rated transparently
Every source is graded by its evidentiary value — blockchain data, exchange imports, and manual entries. The reviewer sees at a glance how solidly the origin of your coins is documented.
No hidden gaps
If part of the history is missing, the report flags it openly. Transparency builds more trust than incomplete figures.
Your data stays with you
The source-of-funds proof is generated right in your browser. Your data does not need to be sent to an external server.
Prove older coins too
Even if your coins came from exchanges that have since shut down, CoinTracking can often still reconstruct the historical data.

Included in your plan — not billed per report
A single review cycle quickly runs to five or ten reports once the reviewer follows up. With CoinTracking, all of that is included in the price.

The report is built to meet the documentation standards banks typically request during AML reviews: every transaction is classified by import method (blockchain, exchange, manual), every source is backed up, and each entry can be checked against an exchange statement or a block explorer. Final acceptance always rests with the bank’s reviewer, but the structure and depth match what AML compliance teams want to see. A short cover letter explaining your situation helps too.
CoinTracking has been around since 2012 and supports historical importers for Mt. Gox, BTC-e, Cryptopia, QuadrigaCX, and many other now-defunct exchanges. If you kept your old CSV exports, you upload them just like an active exchange. For self-custodied holdings, the blockchain remains the source of truth and CoinTracking imports the data directly. Any remaining gaps are flagged openly in the report — an experienced reviewer accepts that more readily than an artfully closed gap.
In an audit or a query from the tax authority, the crypto source-of-funds report is exactly the document the reviewer wants to see, alongside your tax reports and the fiat-side documents (payslips, tax assessments). The report shows every transaction, its source, and its evidentiary strength. The final assessment is up to the reviewer, but the form and content match what a tax audit expects.
DeFi income, staking rewards, and mining are listed separately in the source-of-funds proof. The report shows which source these coins came from and what share they contribute to each withdrawal. The reviewer can see at a glance whether — and to what extent — your withdrawal stems from staking, mining, or other crypto income. Internally these transactions are assigned to the Mining & Staking and Income & Rewards categories.
A few seconds. Once your transaction history is imported, CoinTracking generates the source-of-funds proof right in your browser. The PDF is ready to download instantly.
For insolvencies like Mt. Gox, QuadrigaCX, FTX, Celsius, or BlockFi there are public bankruptcy records. If you filed a claim, your balance at the time is documented there and can be entered as a starting position in your CoinTracking account. For older losses, an old email account with confirmations or an archived CSV is often enough. The report flags any remaining gaps openly instead of hiding them.
Yes. If part of the purchase price comes from selling crypto, a source-of-funds proof is often required. In many EU countries the notary or lawyer handling the closing is legally required to verify the origin of the funds and can refuse to proceed without proof. Usually the CoinTracking source-of-funds report, the matching documents for your fiat payments, and a short cover letter are enough to make the origin of the funds traceable.
