For crypto's first decade and a half, taxes ran on the honor system. Exchanges sent the IRS little or nothing, software barely existed, and millions of people convinced themselves that swapping coins in an app was somehow invisible. That era is over. Beginning with the 2025 tax year, US exchanges report your sales to the IRS on a form built specifically for crypto, Form 1099-DA, and the first wave of those forms landed in mailboxes in early 2026. The rules themselves did not change much; the IRS has called crypto property since 2014. What changed is that the agency can now see the activity. This guide covers what is taxable and what is not, how the gains math actually works, what 1099-DA does and does not tell the IRS, and the entirely legal moves, lot selection, loss harvesting, holding periods, that keep the bill honest but minimal. None of this is individual tax advice; it is the map. For complicated situations, bring a crypto-literate professional.
In 2014 the IRS settled the foundational question in Notice 2014-21: digital assets are property, like stock or a rental house, not currency. Every consequence flows from that single classification.
When you dispose of property, you compare what you got with what you paid, called your cost basis, and the difference is a capital gain or loss. Crypto's twist is that disposal includes more than cashing out to dollars. Trading bitcoin for ether is a disposal of the bitcoin. Spending crypto on a laptop, or a sandwich, is a disposal at the moment of purchase. The property classification means crypto behaves like stock that you sometimes accidentally spend, and the IRS expects a gain or loss calculation every single time.
Meanwhile, crypto that arrives as earnings, from staking, mining, an airdrop, or a client paying your invoice in bitcoin, is ordinary income at its fair market value the day you receive it, exactly as if you had been paid in dollars and immediately bought the coins.
Here is the whole landscape in one sortable table. When in doubt, the pattern is: dollars out of crypto, crypto into other crypto, or crypto into your pocket as earnings all create tax; moving your own property around does not.
A few of these deserve a word. Spending crypto is the rule people break by accident; buying a $5 coffee with coins that appreciated technically creates a reportable gain of a few cents or dollars, which is genuinely silly, and also genuinely the law. Gifts are friendlier than people fear: giving crypto away is not a disposal, and the recipient generally takes over your cost basis, with gift tax paperwork only entering the picture above the annual exclusion, which sits around $19,000 to $20,000 per recipient. Donating long-held appreciated crypto to charity is the quiet superstar: no capital gain for anyone, and a potential deduction at full market value if you itemize, with an appraisal required for larger donations.
How long you held the asset before disposal decides which tax schedule applies, and the gap is large.
Hold for one year or less and the gain is short-term, taxed at the same rates as your salary, anywhere from 10 to 37 percent depending on your bracket. Hold for more than one year and the gain is long-term, taxed at 0, 15, or 20 percent depending on income. High earners may also owe the 3.8 percent net investment income tax on top of either. The 0 percent long-term bracket is real and underused: a household with modest taxable income can realize tens of thousands of dollars in long-term crypto gains and owe nothing federal on them, which makes low-income years, a sabbatical, early retirement, a return to school, structurally good times to realize old gains.
The strategic takeaway is unglamorous: if a position is approaching its one-year birthday and you intend to sell anyway, the difference between month eleven and month thirteen can be a third of the gain. The calendar is the cheapest tax planning tool that exists.
Cost basis is where most crypto tax money is actually won or lost, because most people bought at many different prices over many years.
The default method is FIFO, first in, first out: when you sell, the IRS assumes you sold your oldest coins. But you are allowed to use specific identification instead, choosing exactly which tax lots you are selling, provided you identify them at the time of sale and your records, or your exchange's lot-selection tools, can prove it. The difference is not academic. Suppose you bought one bitcoin at $30,000 in 2023 and another at $60,000 in March 2025, and in June 2026 you sell one for $70,000. Under FIFO you sold the 2023 coin and realized a $40,000 gain. Under specific identification you can sell the 2025 coin instead and realize a $10,000 gain, both long-term. Same sale, same wallet, same day; $30,000 less taxable gain, entirely legally.
Then there is the rule change that took effect January 1, 2025, and now fully shapes 2026 filing: under IRS Revenue Procedure 2024-28, basis must be tracked wallet by wallet and account by account. The old practice of treating all your coins everywhere as one universal pool is dead. Each exchange account and each wallet now carries its own lots, and when you transfer coins between your own wallets, the basis and acquisition dates travel with the specific coins, which your records need to show. If you have years of messy history across defunct platforms, dedicated crypto tax software that imports exchange records and wallet addresses and produces lot-level Form 8949 output has become less a convenience than a necessity.
Form 1099-DA is the crypto equivalent of the 1099-B your stockbroker has always filed, and its arrival is the single biggest enforcement change in crypto's history. The rollout is happening in stages, which is worth understanding precisely because each stage changes what the IRS already knows before you file.
The stage that matters for the return you file in early 2026: custodial brokers, meaning exchanges and platforms that hold customer assets, reported gross proceeds for every sale and exchange you made during 2025. Gross proceeds only; for 2025 transactions the form generally does not include your cost basis, because basis reporting phases in for assets acquired starting in 2026. That gap is a trap to take seriously. If you report nothing, the IRS sees the full proceeds number and can treat all of it as gain. The burden is on your records to show what you actually paid, which is the difference between a tax bill on your profit and a tax bill on your entire sale.
Two boundaries of the system are also worth knowing. First, the separate rule that would have forced decentralized finance front-ends to issue 1099-DAs was repealed by Congress in April 2025, so self-custodied DeFi activity generally will not generate forms, though it remains exactly as taxable and exactly as visible on public blockchains. Second, transfers to your own wallets can make an exchange's records incomplete, which is one more reason the wallet-by-wallet bookkeeping matters. The form is the IRS's view; your job is to file the complete one.
Everything in this section is ordinary income, valued in dollars on the day you receive it, and it stacks a second tax layer on top: the value you declared becomes your cost basis, and any movement after that is a capital gain or loss when you eventually sell.
Staking rewards are income when you gain the ability to sell or move them, a rule the IRS made explicit in Revenue Ruling 2023-14. Mining rewards are income at receipt, and if mining rises to the level of a business, self-employment tax applies too. Airdropped tokens are income when you receive them, even unsolicited ones with a market price. Getting paid for work in crypto, whether wages or freelance invoices, is just compensation: the dollar value on receipt goes on the W-2 or 1099 like any other pay.
The cash-flow hazard hiding in all of this: you owe tax on the value at receipt even if the token later collapses. Someone who earned $5,000 of staking rewards in March owes tax on $5,000 of income even if those tokens are worth $1,500 by April of the next year when the bill comes due. People who earn meaningful crypto income often sell a slice immediately to cover the tax, precisely so a falling market cannot turn an earnings year into a debt.
Crypto's brutal drawdowns come with one genuine consolation: realized losses are useful. Capital losses offset capital gains dollar for dollar, in crypto or anything else, stocks included. Up to $3,000 of leftover loss deducts against ordinary income each year, and anything beyond that carries forward indefinitely.
And here sits crypto's strangest remaining advantage: as of early 2026 the wash sale rule, which bars stock investors from selling at a loss and rebuying within 30 days, still does not apply to crypto, because the rule covers securities and crypto is property. A holder can sell at a loss, harvest the deduction, and repurchase promptly, keeping the position while banking the loss. Two adult caveats: Congress has repeatedly proposed closing this, so check the current state of the law before relying on it, and the IRS can challenge transactions with no economic substance, so same-minute round trips are pushing luck. Losses from coins that became flatly worthless, or that vanished in scams and bankruptcies, live in messier territory; worthlessness can support a loss deduction while personal theft losses are broadly suspended under current law, with fraud-with-profit-motive cases sometimes qualifying. Real money here justifies real professional advice.

Near the top of Form 1040 sits the digital asset question, which every filer must answer, crypto owner or not: at any time during the year, did you receive digital assets as payment or reward, or sell, exchange, or otherwise dispose of a digital asset? Buying with dollars and holding lets you truthfully answer no; selling, swapping, spending, or earning means yes. Answer it honestly, because a false answer on a signed federal return converts a money problem into a perjury problem.
The mechanics, once your records exist, are ordinary: disposals go on Form 8949 and total onto Schedule D; crypto income lands on Schedule 1 or, for a business, Schedule C. A large gain year may also mean quarterly estimated payments to avoid an underpayment penalty, a detail that catches people who cash out in February and forget the IRS expected its slice by the following quarter, not the following April.
One last orientation point. Prices move violently, and every spike and crash in that live chart is someone's taxable event: a swap during the rally, a panic sale in the dip, a harvested loss at the bottom. The market never thinks about your taxes. Twice a year, preferably December and tax season, you should: December for harvesting losses and choosing lots while you can still act, and filing season for reporting it all cleanly. Boring, yes. But in 2026, with the IRS finally holding its own copy of your trading history, boring is exactly what a crypto tax return should be.
Volatility is survivable. Not knowing what you own is not. The Financial IQ Test measures your actual money knowledge, from market basics to risk math, so your conviction is built on understanding instead of a feed full of hype.
Test your Financial IQNo. Buying crypto with dollars and holding it is not a taxable event, no matter how much it rises. You still must answer the digital asset question on your Form 1040 truthfully, but answering yes to receiving or disposing of digital assets is what matters; unrealized gains generate no tax until you sell, trade, spend, or earn.
Yes, every time. Swapping bitcoin for ether is treated as selling the bitcoin at its market value that moment, with gain or loss measured against your cost basis, and then buying ether. Crypto-to-crypto trades have never qualified for like-kind exchange treatment under current law, and this is the rule that surprises casual traders most at filing time.
Increasingly, yes. US exchanges began reporting customer gross proceeds on Form 1099-DA for the 2025 tax year, with cost basis being added for assets acquired starting in 2026. The IRS has also used court-approved summonses against major exchanges for years, and the blockchain itself is a permanent public record. The practical assumption in 2026 is that custodial activity is visible.
The clean fix is to amend the old returns with Form 1040-X and pay what you owed before the IRS contacts you, since voluntary correction generally means interest and possibly penalties rather than something worse. Willfully ignoring it after receiving IRS letters is where real trouble lives. For multiple years or large amounts, this is exactly what a crypto-literate CPA or tax attorney is for.
Often not, and this surprises victims. Personal theft and casualty losses are broadly nondeductible for individuals under current law, though losses from profit-motivated investment fraud have qualified for deduction in some IRS guidance. Documentation and the specific facts matter enormously here, so a scam victim with meaningful losses should get professional advice rather than guessing.
No. Transferring crypto from your exchange account to your own hardware wallet, or between two wallets you own, is not a disposal and triggers nothing. Keep records of these transfers anyway, because under the wallet-by-wallet basis rules your records are what prove the receiving wallet's coins kept their original cost basis and purchase dates.
