Analytical Derivation & Methodology
Under IRS Revenue Ruling 2019-24, cryptocurrency investors who maintain detailed records (transaction IDs, timestamps, cost basis) are legally permitted to use Specific Identification, including HIFO (Highest-In, First-Out).
FIFO (First-In, First-Out) assumes the earliest coins acquired are sold first, which typically results in the lowest cost basis and largest taxable capital gain. HIFO matches sales against the highest acquisition prices first, immediately maximizing cost basis deductions and generating tax-loss harvesting benefits.
Assets held 365 days or less are classified as short-term capital gains and taxed as ordinary income (up to 37% federal). Assets held greater than 365 days receive preferential long-term capital gains tax rates (0%, 15%, or 20%).

Frequently Asked Questions
Yes. Under IRS Notice 2014-21 and FAQ 39-41, taxpayers can use specific identification (including HIFO) if they can document the date/time acquired, cost basis, fair market value, and wallet address of each lot.
HIFO sells your highest-priced purchases first. This minimizes your net taxable gain in the current year, and can even trigger legal capital losses (up to $3,000 per year against ordinary income) to lower your tax bill.
You can select specific identification on each individual sale transaction as long as you maintain consistent cryptographic accounting records and avoid double-counting previously sold lots.
