Coinbase vs Koinly ~$1,900 capital gains tax lots discrepancy after following cleanup attempt (old Coinbase Pro + hardware wallet transfers)

[goldenaxe]

I have transactions all on Coinbase/Coinbase Pro with some transfers to/from a hardware wallet.

• Followed Koinly support’s Scenario 1/ 2 exactly: first, created wallet migration from jan. 1, 2025 after that didn’t improve my situation, tried scenario 2: deleted internal transfers in Coinbase Pro, deleted the Pro wallet, imported only the “Fills” only CSV into the main Coinbase wallet, wallet-based tracking ON, no migration.
• still in scenario 2: remaining old Pro transfers now show as strikethrough/deleted (normal?).
• No unmatched deposits/withdrawals showing up.
• Cost basis method: standard HIFO (not Optimized). Coinbase also set at HIFO, their “missing transaction details” from transactions to/from hardware wallet to coinbase have been supplied with tax info from koinly.

Result: Koinly still shows roughly $1,900 higher realized capital gains than Coinbase’s own gain/loss report. Wondering if there is a way to reconcile this since I’ve only used coinbase and coinbase pro, all data has been uploaded to koinly, any missing transaction details coinbase asks info for has been supplied. Both koinly and coinbase set to HIFO, everything is synced in koinly, no missing purchase data warnings showing in koinly, no missing prices showing in koinly. Tried uploading just csv in coinbase wallet in koinly instead of API that did not work. Current state is transfers deleted from coinbase pro, coinbase pro wallet deleted, coinbase pro “fills” only imported to coinbase wallet. Wallet based tracking on. Everything synced.

Hi @goldenaxe

You should add your Coinbase account preferably via API . Please also add your Coinbase Pro account using the CSV import method by following the instructions in this guide. In addition, make sure to add any hardware wallets or other wallets/addresses you own .

Once everything is connected, please follow the steps in the guide below to ensure your account is fully reconciled and accurate:

If the capital gains P&L in Koinly does not match the figure shown in Coinbase , this is expected. Koinly calculates gains and losses across all your wallets and exchanges together and applies your selected cost basis method , while Coinbase only shows gains and losses from activity on Coinbase alone .
