DeFi tax reporting in 2026 falls almost entirely on you. Decentralized exchanges, lending protocols and self-custody wallets do not issue Form 1099-DA, so every token swap goes on Form 8949 (box I for short-term, box L for long-term), staking and other reward income goes on Schedule 1, and you answer "Yes" to the digital asset question on Form 1040.
This guide covers DeFi tax reporting for the 2025 returns being filed in 2026 and for the 2026 tax year now under way. It explains why no broker form arrives for on-chain activity, how the common DeFi transactions are taxed, which form lines they land on, and how wallet-by-wallet basis tracking works, with a worked example you can follow line by line. If you need the bookkeeping side of digital assets for a company (fair value measurement under ASU 2023-08 and the related disclosures), see our guide to cryptocurrency accounting for digital assets.
Form 1099-DA is the information return that custodial brokers, such as centralized exchanges and hosted wallet providers, file for digital asset sales. The IRS describes the phase-in plainly on its digital assets page: "Brokers must report gross proceeds for transactions effected on or after Jan. 1, 2025," and "Brokers must report basis on certain transactions effected on or after Jan. 1, 2026." The same page says the final regulations "apply to brokers that take possession of the digital assets being sold by their customers."
A second rule, published on December 30, 2024, would have pulled certain DeFi front ends into broker reporting. Congress struck it down under the Congressional Review Act. Public Law 119-5, approved April 10, 2025, states that the rule on "Gross Proceeds Reporting by Brokers That Regularly Provide Services Effectuating Digital Asset Sales" shall "have no force or effect."
The practical result for 2025 and 2026 is a split picture:
| Where the trade happened | Form 1099-DA for 2025 sales | Form 1099-DA for 2026 sales |
|---|---|---|
| Centralized, custodial exchange | Yes, gross proceeds | Yes, gross proceeds, plus basis for covered securities |
| DEX, lending protocol or liquidity pool used from a self-custody wallet | No | No |
Basis reporting from 2026 is limited to "covered" assets bought in the custodial account itself, so even exchange forms will lack basis for older or transferred-in tokens. Our explainer on Form 1099-DA and broker reporting covers the covered and noncovered rules and the boxes on the form itself.
The tax rules for these trades are the same either way. Without a form, the IRS gets no third-party record of your DeFi activity, so your own records are the only support for the numbers you file.
For federal tax purposes, digital assets are property. Every DeFi move falls into one of two buckets: a disposition, which produces capital gain or loss, or a receipt of new tokens as income, which produces ordinary income.
A swap on a decentralized exchange is a disposition of the token you give up. The IRS virtual currency FAQs answer this directly in A16: "If you exchange virtual currency held as a capital asset for other property, including for goods or for another virtual currency, you will recognize a capital gain or loss." The gain or loss is the fair market value of what you received minus your adjusted basis in what you gave up. Swaps into stablecoins count too, even when the dollar value barely moves.
Rev. Rul. 2023-14 holds that when a cash-method taxpayer receives staking rewards, "the fair market value of the validation rewards received is included in the taxpayer's gross income in the taxable year in which the taxpayer gains dominion and control over the validation rewards." The ruling applies the same answer when you stake through an exchange.
The Tax Court reached the same result in Paschall v. Commissioner, T.C. Memo. 2026-46, filed June 4, 2026. The taxpayers argued that staking rewards should be taxed only when sold. The court disagreed, noting that "Even though Mr. Paschall chose not to sell the staking rewards during 2021, he had the ability to do so," and decided the case under section 61 without relying on the revenue ruling. For timing questions, liquid staking tokens and validator setups, our article on crypto staking taxes goes further.
The fair market value you include in income becomes your basis in the reward tokens. When you later sell or swap them, you have a separate capital gain or loss measured from that basis.
The IRS FAQs treat tokens received in an airdrop following a hard fork as "ordinary income equal to the fair market value of the new cryptocurrency when it is received." Governance tokens and protocol incentives handed out to users are commonly reported on the same income-at-receipt basis, though the published guidance speaks to hard forks specifically. Token-based collectibles follow their own rules, covered in our guide to NFT taxes.
The IRS guidance listed on its digital assets page does not address liquidity pool deposits, LP tokens or collateralized DeFi borrowing by name. Practitioners therefore apply the general rules to the facts of each protocol:
Because these positions involve judgment, write down the method you used and why.
Transfers between wallets you own are not taxable. FAQ A38 says the transfer "is a non-taxable event, even if you receive an information return from an exchange or platform as a result of the transfer." Network fees paid in tokens are a separate matter, covered next under the digital asset question.
Once each transaction is sorted into a bucket, DeFi tax reporting uses the same forms as any other digital asset activity.
The digital asset question on Form 1040. The IRS digital assets page says you "must answer 'Yes' or 'No'" to the question about receiving or disposing of digital assets. Answer "Yes" if you swapped, sold, earned staking rewards or received an airdrop. The same page says you can answer "No" if you only held tokens or moved them between your own wallets, "unless you paid a transaction fee with digital assets," since paying a fee in tokens is itself a digital asset transaction.
Form 8949 and Schedule D for dispositions. The Form 8949 instructions for 2025 added new boxes for digital assets: "New boxes G, H, and I for short-term digital asset transactions. New boxes J, K, and L for long-term digital asset transactions." Because DeFi trades come with no Form 1099-DA, they go in box I (short-term) or box L (long-term). The instructions add, "Do not use box C to report digital asset transactions. Use box I," and give the same direction for box F and box L. Totals then flow to Schedule D, explained step by step in our guide to Schedule D and Form 8949.
Schedule 1 for reward income. The IRS page says, "To report income from forks, staking, mining, etc., use Form 1040 (Schedule 1)." If your DeFi activity rises to a trade or business, income and expenses move to Schedule C instead, and self-employment tax comes into play. Entities holding or using crypto in operations face a different set of questions, covered in our article on business cryptocurrency tax implications.
Mixed accounts. Most DeFi users also trade on a centralized exchange. Those sales arrive on Form 1099-DA and go in box G, H, J or K depending on the holding period and whether basis was reported. Keep the two streams separate so your Form 8949 totals reconcile to the broker forms the IRS already holds.
Priya holds ETH in a self-custody wallet and uses a decentralized exchange. All figures are in US dollars at the time of each transaction, and network fees are left out to keep the arithmetic clear. Her 2026 activity:
| Event | Proceeds | Basis | Result | Where it goes |
|---|---|---|---|---|
| Staking rewards received | n/a | n/a | $1,600 ordinary income | Schedule 1 |
| 1 ETH swapped for USDC (held over a year) | $3,400 | $2,300 | $1,100 long-term gain | Form 8949, box L |
| 1,000 USDC swapped for XYZ | $1,000 | $1,000 | $0 gain | Form 8949, box I |
| XYZ swapped for 1,600 USDC | $1,600 | $1,000 | $600 short-term gain | Form 8949, box I |
| 0.5 ETH rewards sold | $1,450 | $1,600 | $150 short-term loss | Form 8949, box I |
Her totals: $1,600 of ordinary income on Schedule 1, $1,100 of long-term gain, and a net short-term gain of $450 ($600 minus $150, plus the $0 USDC line). Combined capital gain is $1,550. The USDC swap still gets its own row even though it shows no gain. Her basis in the staking rewards is the $1,600 she already reported as income, which turns the later sale into a loss. And none of these rows will appear on any Form 1099-DA, so the support for every number is her own transaction log.
Since January 1, 2025, basis is tracked separately for each wallet or account. Rev. Proc. 2024-28 provides a safe harbor "on which taxpayers may rely to allocate unused basis of digital assets to digital assets held within each wallet or account of the taxpayer as of January 1, 2025." The allocation could be done unit by unit or by a global rule. A specific unit allocation had to be completed before the earlier of the first 2025 sale of that type of digital asset or the due date, including extensions, of the 2025 return. The safe harbor does not apply to anything acquired on or after January 1, 2025, which follows the per-wallet rules in the final regulations.
For DeFi users this has two practical effects. First, each self-custody address carries its own pool of basis, so moving tokens between wallets has to carry the original basis and acquisition date with it. Second, if you never documented a 2025 allocation, ask a preparer how to handle the gap before filing, since the deadline has passed for most calendar-year filers. Our guide to crypto cost basis explains the identification methods in more detail.
Crypto tax software can import on-chain history from wallet addresses, but protocol interactions often come through as unlabeled contract calls. Review each one before relying on the output. For every transaction, keep:
Unreported income and figures that do not match information returns are among the common IRS audit triggers, and a clean DeFi log is what lets you show how each number was built.
Do DeFi platforms issue Form 1099-DA? No. The broker reporting regulations apply to brokers that take possession of customer assets, and the separate DeFi broker rule was disapproved by Public Law 119-5 on April 10, 2025. Decentralized exchanges and protocols used from a self-custody wallet do not send a Form 1099-DA, so you report that activity from your own records.
Where do DeFi swaps go on Form 8949? Use box I for short-term transactions and box L for long-term transactions not reported to you on a Form 1099-DA. The 2025 instructions say not to use boxes C or F for digital assets.
Are staking rewards taxed when I receive them or when I sell them? When you receive them. Rev. Rul. 2023-14 includes their fair market value in income when you gain dominion and control, and the Tax Court reached the same result under section 61 in Paschall, T.C. Memo. 2026-46. Selling them later produces a separate capital gain or loss.
Do I check "Yes" on the digital asset question if I only moved tokens between my own wallets? Generally no, unless you paid the network fee in tokens. The IRS treats a fee paid in digital assets as a digital asset transaction, which calls for a "Yes."
How do I find my basis for tokens bought years ago? Start from your purchase records and the per-wallet allocation you made as of January 1, 2025 under Rev. Proc. 2024-28.
