Cryptocurrency tax reporting starts with a simple rule: the IRS treats digital assets as property, so every sale, trade, or purchase you make with crypto during the year is a potential taxable event that belongs on your federal return.1Internal Revenue Service. Frequently Asked Questions on Digital Asset Transactions You report disposals on Form 8949, carry the totals to Schedule D, and answer the digital asset question on the first page of Form 1040. Starting with 2026 transactions, brokers report your cost basis on Form 1099-DA for assets acquired in a custodial account after 2025, which means the IRS now receives much of the same information you do.2Internal Revenue Service. Instructions for Form 1099-DA (2026)
What Actually Triggers a Tax Bill
A taxable event happens when you dispose of a digital asset. Selling crypto for U.S. dollars is the obvious case. Trading one token for another counts too: the IRS views that as disposing of the first asset at its current market value and buying the second at the same price.3Internal Revenue Service. Digital Assets Bought Bitcoin at $20,000 and swapped it for Ethereum when Bitcoin was worth $60,000? You owe tax on a $40,000 gain even though no dollars ever moved.
Spending crypto works the same way. Pay for dinner with a token that has appreciated since you bought it, and the difference between your cost and the fair market value of the meal is a capital gain.1Internal Revenue Service. Frequently Asked Questions on Digital Asset Transactions Size doesn’t matter to the rule. A $12 coffee can produce a reportable gain.
What isn’t taxable: buying crypto with dollars and holding it, or moving crypto between wallets you control. The obligation only starts when you part with the asset for something else of value.
Staking, Mining, Airdrops, and Hard Forks
Rewards from staking are ordinary income, not capital gains, in the year you gain the ability to transfer, sell, or otherwise use them. Revenue Ruling 2023-14 made that explicit for validation rewards.4Internal Revenue Service. Revenue Ruling 2023-14 Mining income follows the same pattern: the fair market value of the coins when they hit your wallet is ordinary income. If mining or staking is a trade or business rather than a hobby, that income goes on Schedule C and is subject to self-employment tax.
Airdrops and hard forks turn on the same “dominion and control” idea. Under Revenue Ruling 2019-24, a hard fork by itself doesn’t create income; you have income when you actually receive units of the new token and can do something with them.5Internal Revenue Service. Revenue Ruling 2019-24 If the tokens land in an exchange wallet that doesn’t support them, the clock hasn’t started. When you do gain control, the fair market value at that moment becomes both your ordinary income and your cost basis for any future sale.
Cost Basis and Holding Period
Your cost basis is what you paid for the asset, including transaction fees. When you sell part of a position, the method you use to identify which units you sold can change the tax outcome dramatically.
The IRS default is first-in, first-out. FIFO assumes the oldest units go first, which usually produces the largest gain for assets that have appreciated. The alternative is specific identification: designating exactly which units you’re selling. Done properly, this lets you pick higher-cost lots to shrink the gain. The catch is that the identification must happen before or at the time of the sale, not months later when you’re preparing your return.1Internal Revenue Service. Frequently Asked Questions on Digital Asset Transactions Without a valid specific identification, you fall back to FIFO within the particular wallet or account.
Holding period determines the rate. Short-term gains (assets held one year or less) are taxed at your ordinary income rate, up to 37%. Long-term gains (held more than one year) get preferential rates:
- 0% for taxable income up to $49,450 single, $98,900 married filing jointly
- 15% above those thresholds up to $545,500 single, $613,700 joint
- 20% above $545,500 single, $613,700 joint
High earners may owe an additional 3.8% net investment income tax. Selling a day before versus a day after the one-year mark can swing your rate by 20 percentage points, so tracking acquisition dates matters.
The Forms: 8949, Schedule D, and the 1040 Question
Every disposal goes on Form 8949 with a description of the asset, the acquisition date, the disposal date, your proceeds, and your cost basis.6Internal Revenue Service. Instructions for Form 8949 Part I is for short-term transactions, Part II for long-term. The totals flow to Schedule D, which nets everything into your overall capital gain or loss.7Internal Revenue Service. Instructions for Schedule D (Form 1040) If you end up with a net loss, you can deduct up to $3,000 against ordinary income ($1,500 if married filing separately), with the excess carried forward to future years.8Office of the Law Revision Counsel. 26 U.S. Code 1211 – Limitation on Capital Losses
The first page of Form 1040 asks whether you received, sold, exchanged, or otherwise disposed of any digital assets during the year. Check “Yes” if you sold crypto, traded one token for another, received staking or mining rewards, got an airdrop, or paid for something with crypto.3Internal Revenue Service. Digital Assets You can check “No” if you only bought crypto with U.S. dollars or held it in a wallet without any dispositions or receipts.9Internal Revenue Service. Determine How to Answer the Digital Asset Question Answering incorrectly in either direction raises audit risk.
What Your Broker Now Sends the IRS
For 2025 transactions, crypto brokers began issuing Form 1099-DA reporting gross proceeds from sales they facilitated. Cost basis reporting was optional. For 2026, brokers must report both proceeds and cost basis for “covered securities,” meaning digital assets acquired after 2025 in a custodial account at that broker.2Internal Revenue Service. Instructions for Form 1099-DA (2026)
Assets you bought before 2026, transferred in from somewhere else, or hold in a self-custody wallet are “noncovered.” A broker may report basis for those voluntarily, but isn’t required to. You’re still on the hook for tracking basis on anything old or migrated. The IRS matches the proceeds on your 1099-DA against your Form 8949, so mismatches surface quickly.
Crypto Held on Foreign Exchanges
U.S. taxpayers with foreign financial accounts exceeding $10,000 in aggregate at any point in the year normally file an FBAR (FinCEN Form 114), separately from the tax return through FinCEN’s BSA E-Filing System.10Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR)11Financial Crimes Enforcement Network. Report Foreign Bank and Financial Accounts The deadline is April 15 with an automatic extension to October 15.12Financial Crimes Enforcement Network. Due Date for FBARs
Whether crypto on a foreign exchange triggers the FBAR is unresolved. FinCEN Notice 2020-2 stated that a foreign account holding only virtual currency isn’t reportable under the current regulations, though FinCEN signaled intent to change that.13Financial Crimes Enforcement Network. FinCEN Notice 2020-2 – Filing Requirement for Virtual Currency As of 2026 no final rule has been published. If the same foreign account also holds fiat currency, the fiat side can make the whole account reportable.
A separate obligation exists under FATCA. Form 8938 attaches to your Form 1040 when specified foreign financial assets exceed thresholds that vary by filing status and whether you live in the U.S. or abroad, starting at $50,000 on the last day of the year for a single U.S. filer.14Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets15Internal Revenue Service. Summary of FATCA Reporting for U.S. Taxpayers If you meet both the FBAR and Form 8938 thresholds, you file both. They go to different agencies and don’t substitute for each other.
Penalties for Getting It Wrong
Fail to file a return, and the penalty is 5% of the unpaid tax per month or partial month late, up to 25%, plus a separate 0.5% per month failure-to-pay penalty and daily-compounded interest at the federal short-term rate plus three points.16Internal Revenue Service. Failure to File Penalty17Internal Revenue Service. Quarterly Interest Rates File but understate what you owe through negligence or a substantial understatement, and the accuracy-related penalty is 20% of the underpayment.18Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments Deliberately omitting crypto gains can push the case into fraud, where the penalty jumps to 75% and criminal prosecution becomes possible.
FBAR penalties run on a separate track. A non-willful failure can cost up to roughly $16,500 per unreported account per year, adjusted for inflation.10Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) A willful violation carries up to the greater of about $100,000 (also inflation-adjusted) or 50% of the account balance at the time of the violation, and the IRS can stack penalties across years.19Internal Revenue Service. National Taxpayer Advocate 2025 Purple Book – Legislative Recommendation 35 That stacking is how FBAR cases sometimes produce penalties larger than the accounts themselves.
Recordkeeping is the practical defense. Keep acquisition dates, prices, lot identifications, and transfer records for every wallet and account. With Form 1099-DA now feeding the IRS’s matching system, the years when incomplete records could quietly disappear are ending.
