Tax Strategy for Crypto Investors (2026 Guide)

Crypto taxation is not conceptually difficult. Digital assets are property, so every disposition is a taxable event measured against basis. The difficulty is entirely in the record keeping, and the rules on how those records must be kept have tightened substantially.

Investors who moved assets across a dozen wallets and exchanges over several years have a reconstruction problem that gets more expensive every year they postpone it.

Every Disposition Is a Taxable Event

Selling crypto for dollars is a disposition. So is trading one token for another, spending crypto on goods or services, and paying a fee in crypto.

Gain or loss is the difference between the fair market value received and the basis in the units disposed of, characterized as short-term or long-term based on the holding period.

Token-to-token trades are the item investors most often overlook. Swapping one asset for another is a sale of the first asset at fair market value, not a like-kind exchange. IRC Sec. 1031 has been limited to real property since 2017, and the IRS position was that crypto never qualified even before that.

Per-Wallet Accounting Changed the Rules

The IRS has moved to a per-wallet or per-account basis tracking requirement for digital assets, replacing the universal pooling approach many taxpayers and software packages used.

Under the universal approach, an investor treated all units of a token across all wallets as a single pool and selected lots from that pool. Under per-wallet accounting, basis must be tracked separately by wallet or account, and a disposition from one wallet can only draw on lots held in that wallet.

This matters for lot selection. An investor holding high-basis units on one exchange and low-basis units on another can no longer sell from one and identify lots from the other.

Transitional guidance permitted a one-time allocation of existing basis across wallets under a reasonable method, documented as of a specified date. Investors who did not perform that allocation have a gap in their records that becomes harder to defend over time.

Specific Identification Requires Contemporaneous Records

The default method is first in, first out within each wallet. Specific identification is permitted and is almost always more favorable, but it requires identifying the specific units at the time of the transaction, not at tax time.

That means the identification must be made in the records or with the broker before or at the time of the sale, specifying the acquisition date, basis, and quantity of the units disposed of.

An investor who sells in March and decides in the following February which lots those were has not made a valid specific identification. The default applies.

Practically, this means using software that records lot selection at transaction time and instructing exchanges accordingly where they support it.

Wash Sales Do Not Currently Apply, But Plan Carefully

IRC Sec. 1091 applies to stock and securities. Digital assets are treated as property rather than securities for this purpose, so the wash sale rules have not applied to most crypto positions.

That has allowed loss harvesting without a 30-day wait: sell at a loss, recognize it, and repurchase immediately.

Legislative proposals to extend wash sale treatment to digital assets have been introduced repeatedly. Investors should treat the current treatment as available now rather than permanent, and should not build a strategy that depends on it continuing indefinitely.

There is also an economic substance consideration. A transaction executed solely to generate a loss with no change in economic position invites scrutiny even without a specific wash sale rule.

Staking, Mining, and Airdrops Create Ordinary Income

Rewards received from staking are includable in gross income at fair market value when the taxpayer gains dominion and control over them. The IRS position, set out in Revenue Ruling 2023-14, is that the income arises upon receipt rather than upon later sale.

That value becomes the basis in the received units, so a subsequent sale produces capital gain or loss measured from that point.

Mining income is ordinary income at receipt as well, and where mining is conducted as a trade or business it is subject to self-employment tax, with the offsetting benefit that equipment and electricity are deductible business expenses.

Airdrops of new tokens are generally income at receipt when the taxpayer has dominion and control, per Revenue Ruling 2019-24.

The practical difficulty is valuation at receipt for illiquid tokens received in high volume. Documenting the methodology used, applied consistently, is the defensible approach.

Charitable Contributions Are Unusually Efficient

Donating appreciated crypto held more than one year to a qualified charity generally produces a deduction at fair market value with no recognition of the gain, subject to the applicable adjusted gross income limitations.

For an investor with a position carrying a very low basis, this is substantially better than selling and donating cash.

Contributions of digital assets exceeding $5,000 generally require a qualified appraisal under IRC Sec. 170(f)(11). The IRS has taken the position that an exchange price does not substitute for an appraisal, and taxpayers have lost deductions entirely for omitting it.

This is a mechanical requirement with an expensive failure mode, and it should be handled before the donation rather than at filing.

Worked Example: Cleaning Up a Portfolio

An investor accumulated positions across four exchanges and three self-custody wallets over six years, with roughly 2,400 transactions including swaps, staking rewards, and transfers between wallets.

They had been filing using a universal pooling method with incomplete records, and had never reported staking rewards as income at receipt.

The remediation reconstructs basis by wallet as of the transition date, documents a reasonable allocation method, and rebuilds the transaction history from exchange exports and on-chain data.

Staking income of $84,000 across three years is identified and reported, which increases income but also establishes basis in those units, reducing gain on their eventual sale by the same amount.

Loss harvesting on positions with $310,000 of unrealized loss is executed with immediate repurchase, generating deductible losses that offset gains realized earlier in the year.

An appreciated position with $12,000 basis and $190,000 value held four years is donated to a donor advised fund with a qualified appraisal, producing a fair market value deduction and eliminating $178,000 of embedded gain.

The cleanup cost several thousand dollars in professional fees and produced a materially better and far more defensible position.

Frequently Asked Questions

Is trading one crypto for another taxable?

Yes. A token-to-token swap is a disposition of the first asset at fair market value. Like-kind exchange treatment under IRC Sec. 1031 has been limited to real property since 2017, and the IRS position was that digital assets never qualified.

Do I have to track basis separately for each wallet?

Yes, under the per-wallet accounting approach that replaced universal pooling. A disposition from one wallet can only draw on lots held in that wallet. Investors who did not perform the transitional basis allocation have a gap that gets harder to defend over time.

Do wash sale rules apply to crypto?

Currently no, because IRC Sec. 1091 applies to stock and securities and digital assets are treated as property. This permits immediate repurchase after harvesting a loss. Legislative proposals to extend the rule have been introduced repeatedly, so treat the treatment as available now rather than permanent.

When is staking income taxable?

At receipt, when you gain dominion and control over the rewards, at their fair market value. That is the IRS position in Rev. Rul. 2023-14. The included value becomes your basis, so a later sale produces gain or loss measured from that point.

Do I need an appraisal to donate crypto?

For contributions exceeding $5,000, generally yes, under IRC Sec. 170(f)(11). The IRS has taken the position that an exchange quoted price does not substitute for a qualified appraisal, and taxpayers have lost the entire deduction for omitting it.
