How is a liquidity pool deposit taxed in the US?
There is no LP-specific IRS guidance, so it is genuinely two-sided: a deposit or withdrawal can be treated as non-taxable or as a crypto-to-crypto disposal depending on your firm's position. CryptoTaxEdge flags liquidity events as a grey area. In the published canonical captures, a liquidity add classifies as a disposal under the house default with full source corroboration, while the matching remove routes to review for a withdraw-and-harvest income-split check, not a different exit policy.
Key takeaways
- There is no LP-specific IRS guidance; a deposit or withdrawal is genuinely two-sided: disposal view or continuity view.
- The house default books the deposit as a disposal under §1001; the continuity alternative is documented alongside and firm-configurable.
- Fee income is its own event: ordinary income at collection, whichever LP position a firm takes.
- Exits are harder than entries: proportions shift (impermanent loss) and accumulated fees need splitting from returned principal.
The two positions, plainly
Disposal view: depositing two tokens and receiving an LP position is an exchange of property for property -- taxable at entry, and again at exit under §1001. Continuity view: the deposit is a contribution to a pooled position you still own -- non-taxable at entry and exit, with economics recognized when the position is finally closed. CryptoTaxEdge's house default is the disposal view; the continuity alternative is documented alongside it, and firms choose.
Why exits are harder than entries
Withdrawals often return the two assets in different proportions than deposited (impermanent loss), plus accumulated fees. Under the disposal view each leg needs a value at exit; under the continuity view the final close crystallizes everything. Fee income is its own event: ordinary income at collection, whichever LP position your firm takes.

Frequently asked questions
Is adding liquidity to a pool taxable?
There are two defensible answers. Under the disposal view, depositing tokens for an LP position is an exchange of property for property, taxable at entry under IRC §1001. Under the continuity view, it is a contribution to a pooled position you still own, non-taxable until the position is closed. The house default is the disposal view, with the continuity alternative documented on the record and the choice applied consistently per firm.
Is removing liquidity from a pool taxable?
It mirrors the entry position. Under the disposal view, the withdrawal is a second exchange and each returned leg needs a value at exit. Under the continuity view, the final close is where the economics crystallize. A withdraw that also harvests accumulated fees mixes principal with income; in the published canonical captures, that shape routes to review for the income split rather than being netted silently.
Are liquidity pool rewards taxable?
Harvested rewards and collected fees are ordinary income when collected under the house treatment, whichever position the firm takes on the deposit itself. Value that accrues inside the position is recognized through the position math at exit under either view.
Do LP tokens have their own cost basis?
Under the disposal view, yes: the LP position takes a basis equal to the value of what was deposited, and the deposited lots close at that value. Under the continuity view, the deposited lots keep their basis and the LP token is a receipt for them. Impermanent loss surfaces at exit under either view; it is a change in what comes back, not a separate deductible event while the position is open.
