DeFi Liquidity Pools and Taxes: Deposits, LP Tokens, Fees and Withdrawals

Providing liquidity to a decentralized exchange is one of the most common things people do in DeFi, and one of the least settled things in crypto tax. You put two tokens in, you get a token back, the pool earns fees, the mix of your tokens changes, and eventually you take something out that is not what you put in.

There is no IRS ruling on liquidity pools. There is a framework of general rules and a recent notice that tells you the IRS knows the question exists. This guide lays out both, and how to build a position that holds together.

What the IRS has said

Notice 2024-57 describes a liquidity provider transaction as transferring one or more digital assets into an automatically executing contract and receiving a different digital asset that represents an interest in a pool of those assets used to facilitate trading, and later redeeming that token for a proportional share of the pool, whether or not you get back the same proportion you put in. It lists these transactions among those brokers are not required to report while the Treasury studies them. The notice says that inclusion creates no inference about their substantive tax treatment, and that its treatment of the redemption does not affect whether compensation for the use of your tokens is reportable under another provision.

That is the full extent of specific guidance. Everything else comes from general principles.

The general rules that apply

• Digital assets are property. Notice 2014-21, Q&A-1.
• Exchanging a digital asset for a different digital asset differing materially in kind or in extent is a disposition, with amount realized equal to the value of what you receive. Treas. Reg. 1.1001-7(b)(1)(iii)(C).
• Property received as compensation or reward is income when you gain dominion and control, and its value becomes basis. Rev. Rul. 2023-14 and Rev. Rul. 2019-24 apply that principle to staking rewards and airdrops.
• Fees paid in crypto to effect a transaction are dispositions of the units used. Treas. Reg. 1.1001-7(b)(1)(ii).

The deposit

When you deposit, say, ETH and USDC into a pool and receive an LP token, the first question is whether you exchanged your ETH and USDC for a materially different asset. An LP token is a claim on a share of a pool whose composition changes with every trade. There is a serious argument that it differs materially from the two tokens you deposited, which would make the deposit a taxable disposition of both.

The contrary argument is that you still own your share of the same assets, now held through a contract, and the LP token is just a receipt. The IRS has not resolved this. Notice 2024-57 describes the transaction without deciding it.

If the deposit is a disposition, you recognize gain or loss on the deposited tokens and take a basis in the LP token equal to its value. If it is not, your deposited tokens keep their basis, and the accounting happens at withdrawal.

Trading fees earned by the pool

Pools typically collect a fee on each trade and add it to the pool, increasing the value of each LP token rather than paying you directly. That looks like appreciation in what you hold, recognized when you withdraw. Some designs pay fees out separately or require you to claim them. When fees arrive as separate tokens you control, the dominion and control principle points toward income on receipt, at value, with that value as basis.

Incentive tokens

Many protocols reward liquidity providers with additional governance or incentive tokens. Those are new units delivered to you as a reward. Applying the reasoning of Rev. Rul. 2023-14 and Rev. Rul. 2019-24, they are most defensibly treated as ordinary income at fair market value when you can claim and dispose of them. Tokens with no reliable market price raise valuation questions; Treas. Reg. 1.1001-7(b)(4) supplies a fallback rule for exchanges, but for income items you will need a documented, reasonable valuation method.

Withdrawal and impermanent loss

When you withdraw, you burn the LP token and receive your share of the pool, usually in a different ratio than you deposited because traders moved the price. The difference between holding the pool position and simply holding the original tokens is what people call impermanent loss. It is an economic concept, not a tax one.

• If the deposit was treated as a disposition, withdrawal is a disposition of the LP token. Gain or loss equals the value of the tokens received minus your basis in the LP token. Each token received takes a basis equal to its value.
• If the deposit was not treated as a disposition, you need a principled way to match what came out against what went in. One common approach treats the withdrawal as the moment the arrangement closes and measures gain or loss on the deposited tokens at that point, with the tokens received taking a value basis.

Either way, the economic result of impermanent loss shows up in your numbers through the values of what you receive. It is not a separate deduction.

Gas fees in DeFi

Each deposit, claim and withdrawal costs a network fee, usually paid in the chain's native token. Paying that fee is a disposition of the units used under Treas. Reg. 1.1001-7(b)(1)(ii). Where the fee effects a sale, disposition or acquisition of a digital asset, the regulations allocate it under 1.1001-7 and 1.1012-1(h). See gas fees and transaction costs.

Building a defensible position

• Choose an approach for deposits and withdrawals and apply it consistently to pools with similar mechanics.
• Record each deposit: tokens, quantities, values, basis, transaction hash.
• Record each claim of fees or incentive tokens as income with date and value.
• Record each withdrawal: tokens received, values, transaction hash.
• Keep a copy of the protocol documentation describing how the pool and token work.
• Consider adequate disclosure of an unsettled position under the section 6662 regulations.

Brokers are not required to report these transactions under Notice 2024-57, and the decentralized platforms themselves are not brokers after the 2025 repeal of the DeFi broker rule. See the DeFi broker rule repeal. Your records are the only records.

A worked example

In 2026 you deposit 2 ETH (basis $2,000 each, value $3,000 each) and 6,000 USDC (basis $6,000) into a pool and receive LP tokens worth $12,000. Months later you withdraw and receive 1.6 ETH worth $4,500 each and 7,500 USDC, a total of $14,700. Along the way you claimed incentive tokens worth $400 when claimed.

• Exchange view: at deposit, you recognize $2,000 of gain on the ETH ($6,000 value minus $4,000 basis) and none on the USDC, and your LP tokens take a $12,000 basis. At withdrawal, you recognize $2,700 of gain ($14,700 received minus $12,000 basis).
• Non-exchange view: nothing happens at deposit. At withdrawal you account for the arrangement as a whole: $14,700 received against $10,000 of combined basis in what you put in, a $4,700 gain.
• Under both views, the $400 of incentive tokens is ordinary income when claimed, with a $400 basis.

The total gain over the life of the position is the same, $4,700. What differs is timing, and whether some of it falls into an earlier year. That is often the real stake in DeFi tax positions.

Positions represented by unique tokens

Some protocols represent each liquidity position as a unique, nonfungible token rather than a fungible LP token, often because the position covers a specific price range. The analysis above still applies. The receipt is different in form, but the questions are the same: was the deposit an exchange, when is income recognized, and how is the withdrawal measured.

A word on scale

A small position held for a few months may produce numbers too small for the method to matter. A large position held through a big price move can produce very different answers under the two approaches to the deposit. Match the effort to the stakes, and if the stakes are high, get the position reviewed before you file rather than after the IRS asks.
