A crypto balance mismatch can be as simple as two apps pricing the same coin at different times. Here’s how to tell when to check the price and when to dig into your transactions.

You open your crypto app, then your tax software, and the totals disagree. Before changing anything, work out what each number is measuring. A current dollar valuation, a quantity of coins and a gain calculated for tax are three different things.
The difference might be a price update. It might also point to missing transactions. The useful question is which part of the comparison differs, and what evidence would explain it.
Start with the label beside the number
Check whether you are looking at current holdings, an available balance or a figure for an earlier date. A portfolio spread across several wallets will not be directly comparable with one platform account. Coins placed in staking products to earn rewards may also appear separately from coins available to move.
Bring the views as close together as you can: the same accounts, assets, currency and date. Check the last successful import or sync. A file uploaded last month cannot contain transactions made since then. Use filters or note the differences in scope; you do not need to delete accounts to make a comparison.
Is the crypto balance mismatch just a price difference?
For each asset, the displayed value combines a quantity and a price. In a simple example, ten units valued at A$2 each produce a total of A$20. The same ten units at A$2.10 produce A$21. The holdings agree even though the valuations differ.
Compare one asset’s quantity first. If it matches, look at the price, valuation time and display settings. If it does not, investigate the transactions and what the balance includes. Do not assume a small difference is harmless or that a large one means coins have disappeared.
Summ’s portfolio documentation makes a useful distinction: its portfolio page describes investment performance, while tax reports use transaction data. A dashboard mismatch alone does not establish that a tax calculation is wrong.
Find out how the balance was built
Some software can show both a balance supplied by a connected platform and a balance calculated from imported transactions. Koinly explains the difference in its support guidance. A delayed platform update can make those views disagree; missing transaction history can also leave a calculated balance wrong.
Check the beginning of that history, as well as the end. An export covering the latest financial year may omit purchases made years earlier. For a coin that does not reconcile, look for its acquisition, subsequent movements and fees. If you moved it between your own accounts, check that the records cover both ends.
How I checked my crypto balance mismatch
For EatCryptoPie’s reconciliation work on 1 November 2026, I used a two-year export of my own Crypto.com history in Koinly and Summ. Crypto.com was the source of the records, not a platform recommendation. This was a limited check of my own data, not a product ranking.
Koinly skipped my staking rows. Its documentation explains the effect: staked assets remain in its calculated balance. A tool can therefore include coins that a platform shows separately from its available balance. In Summ, the visible “Staking Deposit” entries showed coins under “Sent”. That gives a concrete reason to check whether each tool includes the staked coins.
Koinly also warned that purchase history was missing and that it had assumed a zero cost for those coins. The cause of the missing history remained unconfirmed. Neither a balance nor a transaction label establishes the correct tax treatment.
The full reconciliation walkthrough on EatCryptoPie shows the screenshots, checks and unresolved questions, for readers who want to follow the investigation in more detail.
Keep the evidence before making changes
Save the original export. For each discrepancy, note the asset, the two quantities, the relevant transaction and what you checked. Correct an entry when your records support the correction. If you cannot explain it, keep it on an unresolved list instead of adding a balancing transaction simply to make a warning disappear.
The ATO’s record-keeping guidance calls for transaction records, including dates and Australian dollar values at the time of the transactions. Today’s portfolio total cannot provide that history.
Matching quantities are a useful check, but they cannot prove completeness. If both a purchase and a later sale of the same quantity were absent, the ending balance could still look right. That is a reason to inspect the history even after the quantities agree.
Where the question is how a staking arrangement or another transaction should be treated for tax, take the records and the software’s treatment to a registered tax agent. A software label is something to investigate, not a ruling on your circumstances.
If the crypto balance mismatch is still unexplained, pick one asset and trace its transactions in the tool you already use. Write down what you can explain and what you still need to ask a registered tax agent.
