Crypto Wallet-by-Wallet Cost Basis: 6 Things to Settle First

Crypto Wallet-by-Wallet Cost Basis: 6 Things to Settle First

Wallet-by-wallet cost basis means each wallet or account carries its own record of what you paid for the coins in it. For years many investors tracked one pooled pile of bitcoin or ether across everything they owned. Under IRS guidance that started to apply from 2025, that habit is a problem, and fixing it later is harder than settling it now.

The six items below are a checklist, not a ranking. The one firm written up is Crypto Tax Made Easy, a New Jersey firm that lists Cryptocurrency Investors among its specialties. Crypto Tax Made Easy is a vetted Sam's List member and a paying member of our featured program; payment does not buy the language we use or its reviews. You can read how we picked this firm at the end.

1. Why Wallet-by-Wallet Cost Basis Replaces One Pooled Number

The short answer: from 2025 onward, IRS guidance generally expects you to track basis separately for each wallet or account, not as one pool across all of them. Cost basis is what you paid, including fees, and it decides your gain or loss when you sell. If the pool is gone, so is the shortcut of averaging everything you hold.

A pooled number was convenient. It let you sell from Exchange A and assume the cheapest or oldest coins were the ones that left, even if those coins sat in a hardware wallet. Wallet-by-wallet tracking says the coins you sold are the ones that were in the place you sold from.

The limitation: guidance is not a statute, and details can be refined. Treat this post as a map, and ask a tax professional how the current rules apply to your holdings.

2. The Rev. Proc. 2024-28 Transition Rule and What It Allocated

Rev. Proc. 2024-28 is IRS guidance that gave taxpayers a safe harbor for the move to wallet-by-wallet tracking. In general, it let you allocate unused basis, meaning basis for coins you still held, to specific wallets and accounts as of January 1, 2025, using one of the methods the guidance describes and records you kept. After that date, each wallet starts from its own allocated record.

This is the transition step that matters most, because it fixes the opening position of every wallet. An allocation done carefully means later sales can be matched to real basis. One done carelessly can leave a wallet with basis that does not fit the coins in it. The guidance also set conditions on how and when the allocation had to be made and recorded, so check the dates and the method against the text.

The limitation: a safe harbor protects you only if you meet its conditions, and a taxpayer who missed it may be in a different position. Ask a professional whether your allocation was made and documented as the guidance requires.

3. Wallet-by-Wallet Cost Basis and Specific Identification Inside Each Wallet

Specific identification is choosing which lot, meaning which batch of coins bought on a given date at a given price, you sold. Inside a wallet, you can generally identify the units you sold if you can show which ones they were, and the choice can change your tax. Without an identification, the default is generally first in, first out, applied wallet by wallet.

The point of wallet-by-wallet cost basis here is that identification works inside the boundary of the wallet or account. You choose among the lots in that wallet, not among every lot you own anywhere. That makes the lot schedule per wallet the record that matters.

The limitation: identification generally has to be made at the time of the sale, and you need records that support it. A choice reconstructed after the fact may not hold. Ask your preparer how your identification has to be documented.

4. Transfers Between Your Own Wallets and the Basis That Moves With Them

Moving coins between wallets you own is generally not a sale. The basis, and the holding period, are generally supposed to travel with the coins. Under wallet-by-wallet tracking, the receiving wallet needs to inherit the right lots, not an average.

That is where crypto cost basis tracking quietly breaks. A withdrawal from an exchange and a deposit in a wallet are two lines in two places. Unless you log the transfer, with the date, amount, fee and which lots moved, software can treat it as a sale on one side and a purchase at today's price on the other.

The limitation: a network fee on a transfer has its own treatment, and not every tool handles it the same way. Check how your software shows fees, and ask a preparer how they should be handled.

5. Exchange 1099-DA Versus Your Own Records

Form 1099-DA is the information return that brokers of digital assets send to report your transactions. As a general matter, brokers are to report gross proceeds for transactions in 2025, and to report basis for certain covered securities acquired from 2026. The phrasing matters: a broker reports what it can see on its own platform, not your whole picture.

So the form and your records will often disagree, and neither is automatically right. A coin bought on one platform and sold on another can arrive with no basis on the form. A transfer in may show with no cost at all. Your return is based on your records, and a gap between them and the form is something to be able to explain.

The limitation: which transactions and assets are covered, and when, depends on the regulations and can be phased. Do not assume a number on a 1099-DA is your basis. Compare it with your lot records and ask your preparer how to report a mismatch.

6. Who Reconciles Wallet-by-Wallet Cost Basis, and How Often

Decide who owns the work. Someone has to pull the exports, keep the per-wallet lot schedule, match the transfers, compare the totals with each 1099-DA and sign off before filing. For many people that is you, quarterly, with a preparer reviewing before filing, and for a larger or messier history, a preparer doing the reconciliation itself.

A quarterly check is cheaper than an annual rebuild. It catches a missing wallet, a platform that stopped sending reports and a transfer that was logged on one side only, while the trail is fresh. Keep a short log of what you checked and what you changed.

The limitation: a reconciliation shows that records agree with each other. It does not decide the tax treatment of an unusual transaction. For anything new, such as a token swap or a bridge between chains, ask a professional.

Where Crypto Tax Made Easy Fits

Crypto Tax Made Easy is based in Little Silver, New Jersey, serving clients nationwide. Its live profile lists Cryptocurrency Investors, Digital Nomads and High Net Worth Individuals as specialties.

Crypto Tax Made Easy has 6 verified client reviews on Sam's List as of 2026-10-02. Each review is submitted by an individual who identifies as a client of the firm and rates it on communication, subject-matter knowledge, and overall satisfaction. Reviews reflect those individual experiences and do not represent an endorsement by Sam's List. Crypto Tax Made Easy is a paying member of our featured program, and payment does not buy its reviews. Ratings and rankings are not indicative of future performance or results.

Ask whether the firm tracks basis per wallet, how it handled the 2025 transition and how it reconciles a 1099-DA to your own records. The limitation, plainly: the profile does not mention wallet-by-wallet tracking, Rev. Proc. 2024-28 or 1099-DA by name, so ask what is included. No firm can rebuild basis that your records cannot support, and what it can do depends on what you can still pull. You can also browse accountants on Sam's List to compare others.

Frequently Asked Questions

What is wallet-by-wallet cost basis?

It means tracking what you paid for coins separately for each wallet or account, instead of pooling everything you own. IRS guidance generally expects this from 2025 onward. Ask a tax professional how it applies to your holdings and which method you may use.

What is Rev. Proc. 2024-28?

It is IRS guidance providing a safe harbor for moving to wallet-by-wallet tracking, generally by allocating unused basis to specific wallets and accounts as of January 1, 2025. It has conditions on how and when the allocation is made. Confirm yours against the text.

Does a 1099-DA show my cost basis?

Not always. Brokers generally report gross proceeds for 2025 transactions, and basis only for certain covered securities acquired from 2026. Your own lot records still matter. Compare each form with your records and ask your preparer about any mismatch.

Are transfers between my own wallets taxable?

Generally not, since you still own the coins, and basis and holding period generally move with them. You need records showing the transfer was yours. Fees and unusual cases have their own treatment, so confirm with a tax professional.

Before you call anyone, list every exchange and wallet you have used, export each history, note what you held on January 1, 2025 and gather any 1099-DA you received. You can browse accountants on Sam's List, including the firm above, and ask each how it tracks basis by wallet.
