6 Tax Rules to Understand Before You Borrow Against Your Crypto

6 Tax Rules to Understand Before You Borrow Against Your Crypto

The pitch is clean: don't sell, borrow. You keep the upside, you get the cash, and you skip the capital gain.

The first two are usually true. The third one is true right up until the moment it is not, and the moment it stops being true is chosen by your lender, not by you.

Here is what people get wrong about borrow against crypto taxes. Everyone reads the part where taking out a loan is not a taxable event. Almost nobody reads the part where a forced liquidation is a sale, in a year they did not pick, at a price they did not choose, with a tax bill and no proceeds left to pay it. Six rules before you sign.

1. Borrowing Itself Is Generally Not a Disposition

Start with the part that works. A loan is not a sale. You have not disposed of the asset, so there is generally no realized gain, and loan proceeds are generally not income because they come with an obligation to repay.

That is a general principle of debt, applied to a new asset class. It is also the reason this strategy exists at all, and for a holder with a very low basis it can be a real difference in timing.

The caveat is that the principle depends on the arrangement actually being a loan. Which brings us to the next five rules, all of which are about the ways an arrangement stops behaving like one.

2. A Liquidation Is a Sale, on the Lender's Timing

If the collateral gets sold to satisfy the loan, that is a disposition. You report it, calculate gain or loss against your original cost basis, and file it like any other sale on Form 8949 and Schedule D.

The uncomfortable part is who controlled the timing. You did not decide to sell. A price move and a contract term did. And the cash from that sale went to the lender, not to you, so the tax is owed on a transaction that produced no money in your pocket.

This is the single most important sentence in the whole subject: a margin call can generate a tax bill with no proceeds attached to pay it.

3. Ask Whether the Arrangement Transfers Ownership

The label on the document matters less than what the document does with title to the coins.

Some platforms take actual ownership of the collateral and give you a contractual claim back. Some reserve the right to lend your collateral out to third parties, which is called rehypothecation. Those features look like ordinary custody terms in a contract and are not ordinary at all, because an arrangement that transfers the benefits and burdens of ownership can be analyzed as a sale rather than a loan.

Read for three things: who holds title, whether the platform can rehypothecate, and what happens to your collateral if the platform becomes insolvent. If the contract is vague on any of them, that vagueness is the answer.

4. The Interest Is Not Automatically Deductible

Borrowers assume the interest is a write-off because the collateral is an investment. That is not how the tracing works.

Deductibility generally follows what you did with the borrowed money, not what secured it. Money used in a trade or business is analyzed one way, money used to buy investments another, and money used to buy a boat is personal interest, which is generally not deductible at all. Investment interest, where it applies, carries its own limitation tied to net investment income.

Fixed version: decide the use before you borrow, keep the proceeds in a separate account so the tracing is provable, and do not commingle them with personal cash. Reconstructing the use of funds after the fact is the part that fails.

5. DeFi Liquidates Without Calling You

Centralized lenders send a margin call, then a second one, then they act. A protocol does none of that.

DeFi lending liquidates algorithmically the instant a loan-to-value threshold is crossed. There is no notice, no grace period, and no human deciding whether to wait an hour. In a volatile week you can be liquidated during a wick and be back above water twenty minutes later, holding a realized gain you never wanted.

There is a second layer here. Depositing tokens into a protocol sometimes produces a receipt token in exchange, and whether that exchange is itself a disposition is an unsettled question. The honest answer is that the IRS has not addressed it directly, and reasonable practitioners take different positions.

6. Your Basis Records Have to Exist Before You Borrow

Every rule above resolves into one calculation: proceeds minus basis. If the basis is unknown, the default assumption is not in your favor.

Broker reporting on Form 1099-DA now puts more transaction data in the IRS's hands, but basis on assets you moved between wallets years ago is still your problem to substantiate. A liquidation event is a terrible time to discover that a 2019 acquisition has no record behind it.

Before you borrow, get three things in order: cost basis by wallet with acquisition dates, the executed loan agreement, and the liquidation terms in writing, including the exact loan-to-value trigger and whether partial liquidation is possible.

Who Does This Kind of Work

The reason this is specialist work is not the tax law. It is the reconstruction, and the fact that most of the interesting questions do not have a published answer yet.

Crypto Tax Made Easy is a Little Silver, New Jersey firm founded in 2021, now six people, working exclusively on crypto tax and serving clients nationwide.

Crypto Tax Made Easy has 5 verified client reviews on Sam's List as of 2026-09-04. Each review is submitted by an individual who identifies as a client of the firm and rates it on communication, subject-matter knowledge, and overall satisfaction. Reviews reflect those individual experiences, do not represent an endorsement by Sam's List, and are not indicative of future results.

An exclusive focus matters when the guidance is thin. A firm that reconstructs wallet histories every week has already formed a defensible position on the unsettled questions and can tell you where it sits relative to the aggressive end.

The limits worth stating plainly: no accountant can make an unaddressed question certain, fees are a real cost against the tax being managed, and good documentation reduces exposure rather than eliminating it. If the strategy only works assuming you never get liquidated, it is not a strategy.

Frequently Asked Questions

Is taking out a crypto-backed loan a taxable event? Generally no. Borrowing is not a disposition of the asset, and loan proceeds are generally not income because they carry an obligation to repay. That general principle assumes the arrangement is genuinely a loan and does not transfer ownership of the collateral. The IRS has not issued guidance addressing crypto-collateralized loans specifically.

What happens tax-wise if my collateral is liquidated? The liquidation is treated as a sale. You calculate capital gain or loss using the fair market value at liquidation against your original cost basis, and report it on Form 8949 and Schedule D. The difficult part is that the proceeds go to the lender, so the tax can be owed in a year when no cash reached you.

Can I deduct the interest on a crypto loan? It depends on how the borrowed funds were used, not on what secured the loan. Business use, investment use, and personal use are each treated differently, and investment interest carries its own limitation tied to net investment income. Keep the proceeds in a separate account so the use of funds can be traced.

Is depositing crypto into a DeFi lending protocol a taxable event? It is unsettled. Where the deposit produces a receipt token in exchange, there is a reasonable argument that an exchange occurred, and a reasonable argument that it did not. The IRS has not addressed the question directly, so positions vary among practitioners. Get your specific facts reviewed rather than relying on a general rule.
