Bitcoin Like-Kind Exchange: The Tax Rule That Crypto Traders Tried to Use (And Why It No Longer Works)

For a window of time in crypto's early years, some traders believed swapping one cryptocurrency for another could qualify as a tax-free like-kind exchange under IRS Section 1031. It was a compelling argument. No cash changed hands. You just traded Bitcoin for Ether, or Ether for Litecoin. Why should that be a taxable event? The IRS eventually answered that question in definitive terms, and the answer was not what those traders hoped. This article covers what a bitcoin like kind exchange claim actually was, why the IRS rejected it both before and after 2018, what the rules look like in 2026, and what crypto holders need to understand before filing.

What Is a Like-Kind Exchange?

A like-kind exchange, governed by Section 1031 of the Internal Revenue Code, allows an investor to defer capital gains taxes when selling one asset and reinvesting the proceeds into a similar asset. The classic use case is real estate: sell an apartment building, roll the proceeds into a commercial property of equal or greater value, and pay no immediate capital gains tax on the sale. The gain is not forgiven. It is deferred until you eventually sell the replacement property without doing another exchange.

Before 2018, Section 1031 applied to a broad category of property, not just real estate. It covered tangible personal property like machinery and equipment, and some investors argued it should cover intangible property like cryptocurrency. The logic was straightforward: if you could swap one type of industrial equipment for another without triggering a taxable event, why could you not swap Bitcoin for Ether on the same basis?

That argument formed the foundation of the bitcoin like kind exchange position that circulated in early crypto tax discussions.

The Pre-2018 Window: What Traders Claimed

From 2014 through 2017, crypto-to-crypto trades existed in a gray zone. The IRS had issued Notice 2014-21, which established that virtual currency is treated as property for federal tax purposes. But the guidance was silent on whether swapping one cryptocurrency for another could qualify as a like-kind exchange.

Some taxpayers and their advisors concluded it could. Their argument had two parts. First, before 2018, Section 1031 was not limited to real property. It applied to any property held for investment or business use, as long as the exchanged assets were "of like kind." Second, all cryptocurrencies are essentially the same type of property: digital tokens existing on a blockchain, held for investment, with no physical form. Trading Bitcoin for Ether was, in their view, no different from trading one piece of investment property for another.

This was never a mainstream tax position, and no IRS ruling or court case endorsed it at the time. But it gave some traders a plausible argument to avoid reporting gains on crypto-to-crypto swaps during those years.

The Tax Cuts and Jobs Act: The Door Closes in 2018

The Tax Cuts and Jobs Act of 2017 ended the debate for all transactions going forward. Effective January 1, 2018, Congress amended Section 1031 to restrict like-kind exchange treatment exclusively to real property. Personal property of any kind, including vehicles, artwork, collectibles, and digital assets, was explicitly excluded.

From January 1, 2018 onward, every crypto-to-crypto trade is a taxable event. If you swap Bitcoin for Ether and Bitcoin has appreciated since you bought it, you owe capital gains tax on the difference at the time of the swap. The fact that you never converted to dollars is irrelevant. The IRS treats the exchange as if you sold Bitcoin at its fair market value and used the proceeds to buy Ether.

This is the current rule and it is not ambiguous.

The IRS Closed the Pre-2018 Door Too

The TCJA eliminated the argument going forward, but what about traders who had already claimed like-kind exchange treatment on pre-2018 crypto swaps? Many assumed that even if the law changed in 2018, their earlier trades were safe because the pre-2018 version of Section 1031 was arguably broad enough to cover them.

The IRS addressed this directly in IRS Legal Memorandum 202124008, released in June 2021. The IRS examined three specific trading pairs: Bitcoin for Ether, Bitcoin for Litecoin, and Ether for Litecoin. Its conclusion on all three was the same: none of these pairs qualified as like-kind exchanges even under the pre-2018 rules.

The reasoning focused on the actual nature and function of each asset. Bitcoin, the IRS said, was primarily designed and used as a payment network and store of value. Ether was a different kind of asset: it functioned as "fuel" for the Ethereum blockchain, powering smart contracts and decentralized applications in ways Bitcoin never did. Litecoin had its own distinct design parameters. Because these assets served fundamentally different functions and had different underlying use cases, they were not "of like kind" in the legal sense even before 2018.

The practical impact of ILM 202124008 was significant. Any trader who had filed tax returns claiming pre-2018 crypto-to-crypto swaps as like-kind exchanges was sitting on a tax liability that the IRS could assess, plus interest and potential penalties. The memorandum was not a blanket audit trigger, but it made the position clearly indefensible going forward.

What the Rules Look Like in 2026

The like-kind exchange question is settled law at this point. Crypto does not qualify. What has changed in 2026 is how rigorously the IRS can enforce that settled law, and the answer is: much more rigorously than before.

Starting with transactions effected on or after January 1, 2025, centralized crypto brokers are required to report gross proceeds to the IRS via Form 1099-DA. Starting with transactions in 2026, those same brokers must also report adjusted cost basis for "covered" assets, meaning assets acquired and held within the same broker account on or after January 1, 2026. This brings crypto reporting into rough parity with how stocks and bonds are reported.

The DeFi broker reporting rules that would have extended this to decentralized exchanges were repealed under the Congressional Review Act in April 2025, so on-chain activity through non-custodial wallets and DEXs remains outside the 1099-DA reporting framework. But for any crypto held on a centralized exchange, the IRS will receive detailed transaction data directly from the broker starting now.

What this means practically: if you swapped one crypto for another on Coinbase, Binance, or any other centralized platform in 2026, the IRS already knows about it. The burden of proof for claiming any exemption or deferral has never been higher, and there is no like-kind exchange claim available to make.

The PARITY Act: New Legislation Worth Watching

While like-kind exchange treatment for crypto is dead, there is active legislative movement on crypto taxation in 2026 that could affect how traders manage their tax exposure.

The Digital Asset PARITY Act, introduced in April 2026 by Reps. Max Miller (R-OH) and Steven Horsford (D-NV), contains several provisions relevant to crypto investors. It would establish a de minimis exemption for small stablecoin payments under $200, defer staking income taxes for up to five years, and close the crypto wash sale loophole. That last point matters: under current law, you can sell a digital asset at a loss, buy it back immediately, and still claim the tax deduction. Stocks cannot be treated this way under wash sale rules, but crypto currently can. The PARITY Act would end that.

The bill also passed a bipartisan meeting on May 14, 2026, signaling genuine legislative momentum, though it has not yet become law. If enacted, it would not restore like-kind exchange treatment for crypto, but it would change the overall tax landscape in ways crypto traders need to track.

What Crypto Holders Should Actually Do

If you are holding crypto in 2026 and wondering how to manage your tax position, the like-kind exchange question is closed. Here is what actually matters now.

Track your cost basis on every asset, including transfers between wallets. The IRS mandates an account-by-account approach, meaning you cannot aggregate cost basis across different wallets or exchanges. Each account is treated separately.

If you made pre-2018 crypto-to-crypto swaps and claimed like-kind exchange treatment, consider consulting a crypto tax specialist. ILM 202124008 made that position indefensible, and the statute of limitations may still be open on some of those years depending on how the return was filed.

Use the wash sale loophole while it still exists. Unlike stocks, you can currently harvest crypto losses at year-end and immediately rebuy the same asset. The PARITY Act would close this if passed, so 2026 may be one of the last years this strategy is available.

For DeFi activity, on-chain staking, liquidity pool positions, and non-custodial wallet transactions, you are still responsible for tracking and reporting even though brokers are not required to report them on 1099-DA. The IRS has not exempted these activities from taxation. It has only exempted decentralized platforms from the broker reporting requirement.

FAQ

Can you use a like-kind exchange to defer taxes on Bitcoin trades?

No. Since January 1, 2018, Section 1031 like-kind exchanges apply only to real property. Cryptocurrency of any kind does not qualify. Every crypto-to-crypto trade is a taxable event in which you recognize a capital gain or loss based on the fair market value of the asset at the time of the swap.

Could Bitcoin trades qualify as like-kind exchanges before 2018?

The IRS says no. In IRS Legal Memorandum 202124008 (June 2021), the IRS concluded that swaps of Bitcoin for Ether, Bitcoin for Litecoin, and Ether for Litecoin did not qualify as like-kind exchanges even under the pre-2018 version of Section 1031, because the assets served fundamentally different functions and were not of "like kind" in the legal sense.

What is Form 1099-DA and how does it affect crypto traders in 2026?

Form 1099-DA is the IRS reporting form for digital asset broker transactions. Centralized exchanges must report gross proceeds for transactions from 2025 and cost basis for covered transactions from 2026. This means the IRS receives direct transaction data from your broker, significantly increasing enforcement capacity for unreported crypto gains.

Does the like-kind exchange rule apply to NFT trades?

No. NFTs are treated as property for tax purposes, and like-kind exchange treatment does not apply to them. Trading one NFT for another is a taxable event. The IRS has additionally indicated that certain NFTs may be classified as collectibles, which carry a higher long-term capital gains rate of 28% rather than the standard 15% or 20%.

What is the crypto wash sale rule and could it change?

Currently, crypto is not subject to wash sale rules, which means you can sell a digital asset at a loss, immediately repurchase it, and still claim the tax deduction. This is a structural tax advantage over stock investors. The Digital Asset PARITY Act, introduced in April 2026, would close this loophole and bring crypto under the same wash sale restrictions as equities. It has not yet passed into law as of May 2026.

Conclusion

The bitcoin like kind exchange argument was never a sure thing, and it is definitively closed now. The Tax Cuts and Jobs Act ended it for all post-2017 trades. IRS Legal Memorandum 202124008 closed it for pre-2018 trades as well. In 2026, the conversation has moved on entirely: the focus is now on 1099-DA broker reporting, cost basis tracking, the DeFi exemption from broker reporting requirements, and pending legislation like the PARITY Act that could reshape crypto tax strategy before year-end.

If you traded crypto before 2018 and claimed like-kind exchange treatment, that position deserves a second look with a qualified tax advisor. If you are trading now, every swap is taxable, every broker is reporting, and the IRS has more visibility into your crypto activity than at any prior point. The tax strategy that matters in 2026 is not finding a loophole. It is tracking accurately and positioning before the wash sale window closes.
