Is a crypto loan taxable?
No, in the house treatment. Borrowed principal is not income because it arrives with an obligation to repay, and repaying principal is not a disposition of anything. Posting collateral and reclaiming it are served non-taxable as well. The taxable edge is liquidation: when collateral is seized and sold to close the position, the house default books a disposal of the collateral by the borrower.
Key takeaways
- Borrowed principal is not income (it arrives with an obligation to repay), and repaying principal is not a disposition.
- Posting and reclaiming collateral are served non-taxable; the Standard documents the receipt-token asymmetry honestly (GAP-4).
- Liquidation is the taxable edge: the house default books a disposal of the seized collateral under §1001, measured against its basis.
- Interest is a separate strand: deductibility follows the use of the borrowed funds, a determination that belongs to the preparer.
Is borrowing against crypto taxable?
No, in the house treatment: loan proceeds are not an accession to wealth. Every unit received is matched by the obligation to give it back, so the borrower's net position does not improve by borrowing. On the wire, borrow is served non-taxable with no change in beneficial ownership.
Is repaying a crypto loan taxable?
Repay mirrors the borrow: returning principal closes the debt and is served non-taxable the same way. Interest is a separate strand. Most lending protocols accrue it into the amount repaid, and whether the interest component is deductible depends on what the borrowed funds were used for, a determination that belongs to the preparer. One nuance deserves attention when the repayment is made in an appreciated asset acquired after the borrow: using property to satisfy a debt can itself have consequences, and separating principal from accrued interest inside the repay row is the classification half of that work.
Is posting or reclaiming collateral taxable?
Supplying collateral to a lending protocol, typically against a receipt token, is served non-taxable: the taxpayer still beneficially owns what was deposited. Reclaiming it is the same in reverse. One documented asymmetry is worth knowing: the Classification Standard records (GAP-4) that a lending deposit against a receipt token is asserted as settled non-taxable with no exposed alternative and no firm election, while liquid staking, an arguably similar receipt-token structure, exposes both. Treat the absence of a grey block here as an implementation limit rather than a finding that the position is settled. And where the asset reclaimed is a liquid staking token, the applicable analysis is the one on the liquid staking page, a second documented gap (GAP-2).
Is a liquidation taxable? Liquidation is a disposal
When a position falls below its required collateralization and the protocol seizes collateral to close it, the borrower's collateral is sold whether or not the borrower signs anything. The house default books this as a disposal under IRC §1001 by the liquidated party: the collateral is gone, debt was extinguished in exchange, and gain or loss is measured against the collateral's basis. Getting liquidated does not erase the disposal inside the liquidation.
Grey, but not firm-configurable
Liquidation carries a grey block in the Standard, and it is the one grey category that names no alternate position and accepts no firm election. The reason is perspective: the analysis depends on whether the taxpayer is the liquidated party or the liquidator, so a single alternate treatment would be wrong for one of them. The record carries the basis for the split so the reviewer can confirm which side the taxpayer is on. The review contract is unchanged: anything the engine will not assert routes to needs_review with taxable null.
Frequently asked questions
Is an Aave liquidation taxable?
Yes, under the house default. When a lending-protocol position falls below its required collateralization and collateral is seized to close it, the borrower's collateral is disposed of in exchange for debt reduction, a §1001 event measured against the collateral's basis. The record carries the basis for the treatment, and the perspective split between the liquidated party and the liquidator is documented on the grey block. The Aave V3 protocol page shows the shapes.
Can a liquidation produce a loss?
Yes. Gain or loss is measured against the collateral's basis, so high-basis collateral seized in a market drawdown can produce a recognized loss. Getting liquidated does not convert the disposal into something else; it decides only whether the number is a gain or a loss.
Is the interest on a crypto loan deductible?
It depends on what the borrowed funds were used for, and that determination belongs to the preparer. Most lending protocols accrue interest into the amount repaid, so separating principal from interest inside the repay row is the classification half of the work.
