IRS crypto tax rules in 2026: what actually gets taxed

Crypto taxation in the United States rests on one old decision and two new mechanics. The old decision, in place since 2014, is that digital assets are property: not currency, not a special category, but property, which imports the entire capital-gains apparatus — basis, holding periods, disposals — into every wallet. The new mechanics arrived with the 2025 tax year: brokers now report your gross proceeds to the IRS on Form 1099-DA, and the agency’s safe-harbor rules require wallet-by-wallet basis tracking. Together they end the era in which crypto taxes were largely an honor system. This page covers what is taxed, what is not, the forms, and the traps.

Taxable events: the disposal principle

The organizing rule is that dispositions are taxed and acquisitions are not. Selling crypto for dollars is the obvious disposal; the ones that surprise filers are equally taxable: swapping one token for another (a disposal of the first at fair market value), spending crypto on goods or services (a disposal at the purchase price), and paying transaction costs in tokens. Each disposal produces gain or loss equal to proceeds minus cost basis, short-term at ordinary rates for assets held a year or less, long-term at preferential rates beyond that. Income events run on a parallel track: mining rewards, staking rewards (taxable when you gain dominion and control under the IRS’s 2023 revenue ruling), airdrops, and compensation paid in tokens are ordinary income at fair market value on receipt, and that value becomes your basis for the eventual disposal. Not taxable: buying crypto with dollars, holding through any amount of appreciation, moving assets between your own wallets, and gifting within the ordinary gift-tax exclusions.

The reporting revolution: 1099-DA and wallet-by-wallet

Two changes define the current era. First, broker reporting: custodial exchanges and brokers began filing Form 1099-DA for the 2025 tax year, reporting gross proceeds from customer sales to the IRS, with cost-basis reporting phasing in for 2026 transactions. The practical meaning is that the IRS now receives your sales figures directly, and mismatches between what brokers report and what returns show generate automated notices, exactly as they long have for securities. Decentralized and non-custodial activity is not broker-reported, but the on-ramps and off-ramps largely are, which is how the picture assembles. Second, basis allocation: since January 1, 2025, under the IRS safe-harbor framework, taxpayers must track cost basis wallet-by-wallet and account-by-account, retiring the universal pooling many filers used to cherry-pick lots across platforms. Specific identification of lots remains available within each wallet with adequate records; the default is first-in-first-out. The compliance upshot is unglamorous and decisive: contemporaneous records — acquisition dates, amounts, fair values, per wallet — are now the difference between a defensible return and an unanswerable notice.

Forms, the 1040 question, and what still does not apply

The filing machinery: disposals are itemized on Form 8949 and summarized on Schedule D; ordinary-income events land on Schedule 1 or Schedule C (self-employment treatment, with expenses, for business-scale mining or validation); and every filer answers the digital-asset question on Form 1040’s first page, which asks whether you received, sold, exchanged, or otherwise disposed of digital assets during the year. Answering it falsely is itself a false-statement problem independent of any tax due, and checking yes for mere purchases or holding is not required — the question targets receipts and disposals. Two persistent quirks complete the picture. The wash-sale rule, which bars claiming losses on securities repurchased within thirty days, still does not apply to digital assets by statute, meaning loss harvesting with immediate repurchase remains mechanically available, a gap Congress has repeatedly proposed closing — watch this space, it is the likeliest near-term change. And the $10,000 business-receipt reporting requirement enacted for digital assets remains deferred pending regulations for crypto specifically. State taxation layers on top of all of it, with most states following federal characterization at their own rates.

State taxes and the records that survive an audit

Federal rules are half the bill: most states tax crypto gains as income at their own rates, following federal characterization, which makes state residency a material variable — the zero-income-tax states (Texas, Florida, Washington, Wyoming among them) tax no crypto gains at all, while California’s top rate stacks over 13% onto federal liability, and a handful of states are experimenting with crypto-specific provisions, from payment acceptance to targeted exemptions. State filing follows federal in structure, gains flow from the federal return, but audits do not: state agencies increasingly run their own matching against the same broker data.

The compliance core, at both levels, is records, and the standard is knowable in advance: for every acquisition, the date, amount, source, and dollar value at receipt; for every disposal, the date, proceeds, and the specific lots disposed; per wallet, per account, since the 2025 allocation rules. Exchange histories cover custodial activity, but bridges, self-custody moves, DeFi interactions, and chain migrations are where reconstructions fail years later, which is why the record habit belongs at transaction time — the hashes, the amounts, the dates, captured when they are free, because they are unpurchasable retroactively as interfaces disappear. Tax software can assemble much of the picture from addresses and API keys; its output is only as complete as the wallet list it is given, and the filer, not the software, signs the return.

Cost basis in practice

Basis is where most crypto tax errors originate, and the rules changed recently enough that habits formed under the old regime now produce wrong answers.

The default is first-in, first-out. Absent adequate records supporting a different identification, disposals are treated as coming from the earliest acquired lots, which in an appreciating asset generally maximizes gain. Filers who assume a different method without documentation are making an assertion they cannot support under examination.

Specific identification remains available, within limits. A filer with adequate records may identify which lots were disposed, which permits selecting higher-basis lots to reduce gain. The records must be contemporaneous and sufficient to identify the specific units, and the identification must occur no later than the time of the transaction and not reconstructed at filing.

Wallet-by-wallet is now mandatory. Since the beginning of 2025, basis must be tracked per wallet and per account under the safe-harbor allocation framework, retiring the universal pooling approach many filers had used to select favorable lots across platforms. Taxpayers holding assets across multiple wallets at the transition were required to allocate existing basis among them under the safe harbor, and that allocation, once made, governs.

The practical consequence deserves emphasis because it is the single largest compliance shift of the era. A filer who moved assets between wallets before 2025 and never tracked which units went where has a reconstruction problem that grows harder every year, and the exchanges cannot solve it because they never saw the off-platform moves. Basis reconstruction is the most common reason crypto tax preparation costs what it does.

The hard cases

Beyond ordinary buying and selling sit a set of activities where the treatment is either genuinely unsettled or settled in ways that surprise people. What follows describes general principles and is not a substitute for advice on any specific situation.

Staking rewards are ordinary income at fair market value when the taxpayer gains dominion and control, under a 2023 revenue ruling, with that value becoming basis for the eventual disposal. The timing question — whether control arises at accrual or at withdrawal — has practical consequences on locked or delayed-unbonding networks and has been litigated.

Lending and yield products generally produce ordinary income on the return, with the treatment of the principal depending on whether the arrangement transferred ownership. Products that transfer assets to a platform in exchange for a yield obligation raise questions the 2022 lending collapses made concrete for many holders.

Wrapping and bridging occupy genuinely uncertain ground. Converting a token into a wrapped representation, or moving it across chains through a lock-and-mint mechanism, may or may not constitute a disposal depending on whether the taxpayer’s property interest changed, and no authoritative guidance squarely addresses it. Conservative practice treats economically identical positions as continuing and documents the reasoning; aggressive positions in either direction carry risk.

Liquidity provision typically involves an exchange of assets for a pool position, which has disposal characteristics, followed by income accrual and a further disposal on exit. The compounding of those events across many small transactions makes automated tracking close to essential.

Airdrops are ordinary income when the taxpayer has dominion and control, valued at receipt, including tokens received without any action by the recipient, which is why unsolicited airdrops of illiquid tokens create an unpleasant problem: taxable value at receipt and possibly no market in which to sell.

Hard forks producing new tokens follow the same principle, with income recognized when the taxpayer can transfer, sell, or otherwise dispose of the new asset.

Mining is ordinary income at receipt, and business-scale operations report on a trade or business basis with deductible expenses, depreciation on equipment, and self-employment tax exposure, which is a materially different calculation from casual mining reported as other income.

NFTs are property like other digital assets, with the additional question of whether a particular NFT is a collectible for capital gains purposes, which would apply a higher maximum long-term rate. Treasury has indicated a look-through approach to that question.

DeFi and the reporting gap

The most important structural fact about crypto taxation in 2026 is asymmetric visibility, and understanding it explains both the enforcement posture and the risk profile.

Custodial exchanges and brokers now report customer proceeds to the IRS on the digital asset information return, with basis reporting phasing in. That means for the portion of activity that touches a regulated on-ramp or off-ramp, the agency receives data directly and can match it against returns automatically, exactly as it has done with securities for decades.

Decentralized activity is not reported that way. Swaps on decentralized exchanges, lending protocol interactions, liquidity provision, and self-custody transfers generate no information return. The regulatory attempt to extend reporting to decentralized front ends was contentious and did not survive in the form originally proposed.

The gap is not an exemption, and treating it as one is the most expensive mistake available in this area. The obligation to report income and gains does not depend on whether a third party reported it, the blockchain is a permanent public record, analytics capabilities available to the agency are substantial and improving, and the on-ramp and off-ramp reporting that does exist frequently reveals the existence of activity in between. A filer whose exchange reported a large withdrawal and a later large deposit has already told a story about what happened while the funds were elsewhere.

Losses, harvesting, and the gap that persists

The loss rules contain the single most exploited feature of crypto taxation, and its expected lifespan is short.

Capital losses offset capital gains without limit and offset up to a defined amount of ordinary income annually, with the remainder carrying forward indefinitely. That is ordinary and unremarkable.

What is not ordinary is that the wash-sale rule, which disallows a loss when substantially identical securities are repurchased within thirty days on either side of the sale, applies by statute to securities and has not been extended to digital assets. The mechanical consequence is that a holder can realize a loss and immediately reacquire the same position, harvesting the deduction without changing exposure. Congress has repeatedly proposed closing this, revenue estimates for doing so are substantial, and its continued availability is best treated as temporary. Anyone relying on it should verify current law each tax year, because a change would likely apply prospectively from its effective date instead of being announced in advance.

Two related points. Worthless or abandoned assets present their own difficulties, since claiming a loss generally requires a disposition or an identifiable event fixing worthlessness, and a token that simply becomes illiquid may not qualify. And theft and casualty losses for individuals have been substantially limited since 2017, which means the tax treatment of assets lost to a hack or a fraud is considerably less favorable than most victims expect.

Enforcement, penalties, and the reporting question

The compliance environment has hardened, and the specifics are worth knowing.

The digital asset question on the first page of the individual return asks whether the filer received, sold, exchanged, or otherwise disposed of a digital asset during the year. Answering falsely is a false statement on a signed return independent of any tax owed, and it removes the innocent-mistake defense from every subsequent dispute. Merely purchasing and holding does not require a yes.

Ordinary accuracy-related penalties apply to underpayments, with higher penalties for substantial understatements and fraud, plus interest. Failure to file information returns carries its own penalties for businesses. And criminal exposure exists for willful evasion, which is prosecuted and has produced convictions in this sector.

Foreign account reporting remains genuinely unsettled for digital assets. Whether holdings on non-US exchanges trigger foreign bank account reporting obligations has been the subject of proposed changes and shifting guidance, and the conservative position taken by many practitioners differs from the minimum the current rules clearly require. Anyone holding meaningful balances on offshore platforms should obtain specific advice instead of relying on general summaries, including this one.

The direction of travel across all of it is toward the treatment securities have received for decades: third-party reporting, automated matching, and penalties calibrated to a system that assumes the agency already knows.

Building a defensible position

The difference between a filer who handles an inquiry in an afternoon and one who spends months on it is almost entirely record architecture, and the requirements are knowable in advance.

Capture at transaction time. For every acquisition: date, amount, source, and dollar value at receipt. For every disposal: date, proceeds, and the specific lots. For every transfer between your own wallets: date, amount, sending and receiving addresses, and transaction hash. The last category is the one everyone skips and the one that breaks reconstructions, because a transfer looks identical to a disposal on chain unless you can show both ends were yours.

Maintain a wallet inventory. Tax software assembles a picture from the addresses and API connections it is given, and its output is only as complete as that list. A wallet omitted from the inventory produces a return that is confidently wrong, and the filer signs it.

Reconcile against broker reporting. Where a platform issued an information return, the figures on it should tie to the return. Mismatches generate automated notices, and the cheapest time to resolve a discrepancy is before filing rather than after a letter arrives.

Document positions on unsettled questions. Where treatment is genuinely uncertain — wrapping, bridging, timing of staking income — the defensible approach is a consistent position with contemporaneous reasoning, applied uniformly across years. Inconsistency across periods is what turns an arguable position into an indefensible one.

Keep records longer than you expect. Basis follows an asset for its entire holding period, which for long-term holders means records from years ago remain live. Exchanges close, interfaces change, and blockchain explorers reorganize; local copies of the underlying data are the only thing that persists.

None of this is specific to crypto in principle, and all of it is harder in practice, because a securities investor’s broker maintains this record automatically and a self-custodying crypto holder is their own recordkeeper. That asymmetry, more than any rate or rule, is what makes crypto tax compliance genuinely burdensome.

What to watch

The wash-sale extension. The single most likely rule change, repeatedly proposed with substantial revenue estimates attached. Its enactment would end immediate-repurchase loss harvesting, probably prospectively, and anyone relying on the current gap should treat each tax year as potentially the last.

Basis reporting phase-in. As brokers begin reporting cost basis rather than proceeds alone, the matching the agency can perform becomes far more precise, and discrepancies that previously required an inquiry will surface automatically.

DeFi reporting. The question of whether and how decentralized front ends might be brought into information reporting has been contentious and remains unresolved. Any renewed rulemaking would be the most consequential development in this area.

Foreign account treatment. Whether digital assets held on non-US platforms clearly fall within foreign account reporting obligations has moved and may move again. This is the area where the gap between conservative practice and clear requirement is widest.

State activity. States are increasingly running their own matching against broker data and experimenting with crypto-specific provisions. State treatment generally follows federal characterization, but enforcement and rates do not.
