Decentralized finance (DeFi) lets you stake, lend, provide liquidity, swap, and farm yield without a traditional intermediary. The technology moved faster than the tax code, and the Internal Revenue Service (IRS) has issued direct guidance on only a handful of these activities. The result is a field with some settled rules and several genuine gray areas. This guide walks through the most common DeFi activities, explains where the IRS has spoken clearly, and is honest about where it has not. It is written for a general U.S. audience.
Everything that follows builds on one rule. In IRS Notice 2014-21, the agency established that, for federal tax purposes, cryptocurrency is treated as property rather than currency. That means disposing of a token — selling it, trading it, or spending it — generally triggers a capital gain or loss measured against your cost basis, while receiving new tokens as a reward generally produces ordinary income at fair market value. DeFi simply applies these two ideas to more exotic activities, and the hard part is deciding which activity counts as a "disposal" and which counts as "receipt of income."
Staking is one of the few DeFi activities the IRS has addressed head-on. In Revenue Ruling 2023-14, the IRS concluded that when a cash-method taxpayer stakes cryptocurrency and receives reward tokens, the fair market value of those rewards is included in gross income in the year the taxpayer gains "dominion and control" over them — meaning the moment you can sell, transfer, or otherwise dispose of them. The dollar value at that moment is ordinary income.
That same fair market value becomes your cost basis in the reward tokens. When you later sell or trade them, you calculate a separate capital gain or loss from that basis. So a single batch of staking rewards is taxed across two stages: ordinary income at receipt, then capital gain or loss at disposal.
One nuance worth flagging: when "dominion and control" actually occurs can be ambiguous. Rewards that are locked, subject to an unbonding period, or not yet claimable may not be taxable until they truly become available to you. Document when you could first move each reward.
Suppose you stake ETH and, over a quarter, receive reward tokens that are worth $600 in total at the moments you gain control of them.
If the tokens had instead fallen to $450 when you sold, you would report the same $600 of income at receipt and a $150 capital loss on the sale. The income does not disappear just because the price dropped afterward — a common and painful surprise.
When you lend crypto through a DeFi protocol and earn interest or yield, that yield is generally ordinary income at its fair market value when you receive or can access it. Conceptually it resembles interest on a deposit, and the same dominion-and-control timing principle from Revenue Ruling 2023-14 is a reasonable guide for when the income is recognized. As with staking, the value you report becomes the basis for those tokens, and a later disposal is a separate capital event.
Swapping one token for another on a decentralized exchange (DEX) such as Uniswap is a taxable disposal, exactly like a crypto-to-crypto trade on a centralized exchange. Even though no cash changes hands, you are treated as selling the token you give up at its fair market value and acquiring a new one. You compute a capital gain or loss on the token you disposed of, and the token you receive takes a new cost basis equal to its value at the swap. Gas fees paid in crypto can themselves be a small disposal of that gas token.
Providing liquidity is where the rules get murky. When you deposit two tokens into a liquidity pool, you typically receive an LP token representing your share. The unsettled question is whether depositing your assets and receiving the LP token — and later burning the LP token to withdraw your assets — is itself a taxable disposal.
The IRS has not issued guidance resolving this, so reasonable professionals take different positions. Any trading fees, rewards, or governance tokens you earn while providing liquidity are separately treated as ordinary income when you gain control of them. Whatever position you take, document your reasoning and apply it consistently.
The IRS addressed both in Revenue Ruling 2019-24. It concluded that a taxpayer who receives new cryptocurrency from a hard fork (via an airdrop of the new coin) has ordinary income equal to the fair market value of the new tokens when the taxpayer gains dominion and control over them. The same principle is generally applied to other airdropped tokens: if you can transfer or sell them, you have income equal to their value at that moment, and that value becomes your basis. An airdrop you cannot yet access or that has no market value when received may not produce income until those conditions change.
Wrapping a token (for example, ETH to wETH) or bridging it to another chain is another open question. One camp argues these are mere format changes that leave your economic position unchanged, so no disposal occurs. Another camp notes that you receive a technically different token, which could be read as a taxable exchange under the property rules. The IRS has not directly addressed wrapping or bridging, so this remains debated. Conservative taxpayers track these events carefully even if they do not report a gain, so they can support whichever position they take.
Liquidity-mining rewards, yield-farming incentives, and governance tokens distributed for using a protocol are generally ordinary income at fair market value when you gain control of them, mirroring the staking analysis. Their basis is that same value, and a later sale is a capital event. The basis of airdropped or rewarded tokens is the income you already recognized — not zero — which prevents double taxation of the same value when you eventually sell.
| DeFi activity | Likely treatment | Authority / status |
|---|---|---|
| Staking rewards received | Ordinary income at FMV on receipt | Revenue Ruling 2023-14 |
| Selling staking/reward tokens later | Capital gain or loss vs. basis | Notice 2014-21 (property) |
| Lending / yield interest | Ordinary income at FMV on receipt | By analogy; no direct ruling |
| Swapping tokens on a DEX | Capital gain or loss (taxable disposal) | Notice 2014-21 (property) |
| Depositing / withdrawing from a liquidity pool | Possibly a taxable disposal — unclear | No IRS guidance; debated |
| Liquidity-mining / governance token rewards | Ordinary income at FMV on receipt | By analogy to staking |
| Airdrops and hard-fork coins | Ordinary income at FMV when controlled | Revenue Ruling 2019-24 |
| Wrapping (ETH → wETH) / bridging | Disposal vs. non-event — unclear | No IRS guidance; debated |
The honest summary is that DeFi tax guidance is incomplete. The IRS has spoken clearly on staking (Revenue Ruling 2023-14), on airdrops and forks (Revenue Ruling 2019-24), and on the foundational property rule (Notice 2014-21), but it has not addressed liquidity pools, wrapping, bridging, or many other DeFi mechanics. Where the IRS is silent, you and your advisor must take a reasonable position based on existing principles. Two practical habits matter most:
A reminder on authority: the clear rules here trace to IRS guidance — Notice 2014-21, Revenue Ruling 2019-24, and Revenue Ruling 2023-14. Where this guide says an area is unclear, that reflects the genuine absence of IRS guidance, not a settled answer. The agency continues to update its digital-asset positions, so confirm current rules with the IRS directly or a qualified CPA before filing.
Yes. Under Revenue Ruling 2023-14, staking rewards are ordinary income at their fair market value when you gain dominion and control over them — that is, when you can sell or transfer them. A later sale is a separate capital gain or loss measured from that same value. The income is owed even if the token's price later falls.
It is unclear. The IRS has not addressed whether depositing assets for an LP token (or burning the LP token to withdraw) is a taxable disposal. Some advisors treat it as a taxable exchange; others treat the LP token as a non-taxable receipt for assets you still own. Pick a defensible position with a crypto-savvy CPA and apply it consistently.
This is debated and the IRS has not issued direct guidance. One view treats wrapping and bridging as non-events because your economic position is unchanged; another reads receiving a different token as a taxable exchange. Track these transactions carefully so you can support whichever position you take.
Under Revenue Ruling 2019-24, tokens from an airdrop or hard fork are ordinary income at their fair market value when you gain dominion and control over them. That value becomes your cost basis, so a later sale produces a separate capital gain or loss.
