8 Things the IRS Per-Wallet Cost Basis Rule Changes for Active Crypto Traders The IRS finalized its digital asset broker reporting regulations, and one change is quietly causing chaos for active traders: per-wallet cost basis tracking. Under the final regulations and Rev. Proc. 2024-28, the universal method — treating all your holdings of a given token as one big pool regardless of where they sit — is gone for transactions starting January 1, 2025. If you hold crypto across multiple exchanges and self-custody wallets, your tax calculation just got more complicated. Here's what actually changed under the IRS per-wallet cost basis rule and what it means for how you trade, transfer, and report in 2026. 1. The Universal Method for Crypto Is Gone — Every Account Is Its Own Pool You can no longer treat your BTC on Coinbase, your BTC on Kraken, and your BTC on your Ledger as one combined cost basis pool. Under the new IRS per-wallet rule, basis must be tracked at the account or wallet level. That means when you sell BTC from Coinbase, the basis calculation pulls only from BTC lots that were acquired on Coinbase. What you paid for BTC that now lives on your hardware wallet is irrelevant to that transaction. For traders who moved assets around frequently based on fee rates or liquidity, this creates a lot of basis allocation work — especially retroactively. Rev. Proc. 2024-28 provided a safe harbor for allocating pre-2025 unused basis across wallets, but the allocation had to be reasonable and documented. If you haven't done it, that's the first conversation to have with a crypto tax professional. 2. Transfers Between Wallets Aren't Taxable, But Crypto Cost Basis Tracking Still Follows Them Moving crypto from your Coinbase account to your Ledger hardware wallet is not a taxable event. The IRS has been consistent on this: a transfer between wallets you own isn't a sale. But under per-wallet tracking, that transfer establishes a new basis lot in the receiving wallet. You need documentation showing the original acquisition cost carried over — and you need to record the transfer date and amount. If you can't prove the basis on assets in a self-custody wallet, the IRS's position is that it may assign zero basis on eventual sale. That turns a transfer you thought was tax-neutral into a fully taxable gain. 3. Specific Identification Is Now More Valuable Than FIFO for Most Active Traders FIFO (first in, first out) has been the default for many traders because it's simple. Under per-wallet rules, defaulting to FIFO within each account often means selling your oldest —...
