Cryptocurrency Tax in the USA 2026 — The Complete IRS Guide

The IRS established cryptocurrency tax treatment in Notice 2014-21, which classifies digital assets as property rather than currency. General federal tax principles applicable to property transactions therefore apply to every crypto event.

Because crypto is property, every disposal triggers a taxable event. This includes selling for US dollars, swapping one token for another, spending crypto on goods or services, and gifting above the annual exclusion. Each event produces a capital gain or loss equal to fair market value at disposal minus cost basis.

The IRS confirmed in Revenue Ruling 2023-14 that proof-of-stake rewards become ordinary income at the moment the taxpayer gains dominion and control. Mining rewards follow the same rule under earlier IRS guidance.

FIFO (first in, first out) is the default cost basis method according to the IRS, though specific identification is permitted where the taxpayer can document which units were sold. From 2025, brokers report on a wallet-by-wallet basis under final Treasury regulations, ending the universal accounting approach.

Every Form 1040 since 2020 has carried a digital asset question that requires a yes or no answer. Answering no while owning or transacting in crypto is a perjury risk according to IRS guidance.

Capital gains and losses are reported on Form 8949 with totals flowing through to Schedule D. Income items — staking, mining, airdrops, payments received — are reported on Schedule 1 or Schedule C depending on whether the activity rises to a trade or business.

The single biggest tax driver in the US is holding period. Crypto held for one year or less produces short-term capital gains taxed at ordinary income rates from 10% up to 37% according to IRS digital assets guidance.

Hold for more than one year and the same gain becomes long-term capital gain, taxed at 0%, 15%, or 20% depending on taxable income. For most middle-income taxpayers this is a substantial reduction.

Ordinary income treatment applies to staking rewards, mining rewards, airdrops, hard fork tokens, DeFi yield characterised as income, and crypto received as wages or for services. These are taxed at fair market value on the date of receipt, with that value becoming the cost basis for any later capital gain or loss.

High-income taxpayers face an additional 3.8% Net Investment Income Tax on capital gains and other investment income above $200,000 single or $250,000 married filing jointly, according to the IRS.

Self-employed mining or staking activity that rises to a trade or business adds 15.3% self-employment tax on net income up to the Social Security wage base.

The wash sale rule under IRC Section 1091 currently applies to securities and not to cryptocurrency, according to current IRS guidance. Pending legislation has repeatedly proposed extending it to digital assets.

The US does not apply a percentage discount the way Australia does. Instead, the IRS taxes long-term gains at preferential bracket rates that depend on total taxable income.

For 2026, the IRS-published thresholds put the 0% long-term capital gain rate on roughly the first $48,350 of taxable income for single filers and roughly $96,700 for married filing jointly. The 15% rate covers the broad middle range, with 20% kicking in above roughly $533,400 single and $600,050 joint. Confirm current thresholds with the IRS as they are inflation adjusted each year.

Practical example: a single filer with $60,000 of regular taxable income and a $20,000 long-term crypto gain pays 0% on the first ~$13,000 of that gain (the portion under the 0% threshold remaining) and 15% on the rest, according to the bracket structure.

Holders within one year of the 12-month threshold should weigh whether to defer a sale into long-term territory. The rate difference between a 22% short-term bracket and a 15% long-term rate on a $50,000 gain is $3,500 of tax.

The Net Investment Income Tax adds 3.8% on capital gains for higher earners, layered on top of the long-term rate.

The IRS has used John Doe summonses against major exchanges since 2016 — the first targeted Coinbase and forced disclosure of accounts above $20,000. Similar summonses have hit Kraken (2021), Circle, and SFOX. Every named exchange has produced records.

Under the Infrastructure Investment and Jobs Act and final Treasury regulations published in 2024, US-based brokers must file Form 1099-DA reporting digital asset transactions starting in tax year 2025. Gross proceeds reporting begins with the 2025 tax year and cost basis reporting follows in 2026 according to the IRS.

FinCEN requires US persons with foreign financial accounts above $10,000 to file an FBAR. Whether crypto held on a foreign exchange triggers FBAR is unresolved, but a parallel Form 8938 obligation already applies to certain foreign holdings according to IRS rules.

The IRS Criminal Investigation division has built a dedicated crypto enforcement team since 2020 and has secured multiple high-profile convictions for crypto tax evasion.

Voluntary disclosure before an exam typically reduces penalties under existing IRS programs.
