If you took out a crypto-backed loan in 2025, there is a good chance you will receive a brand-new tax form in early 2026: Form 1099-DA, the IRS’s first dedicated digital-asset reporting return. The form is short. The rules behind it are not. This guide walks through exactly when a crypto loan does and does not generate a 1099-DA, how to read the form when it lands, and the three places it most commonly trips up everyday borrowers.
What Form 1099-DA actually is
Form 1099-DA is the digital-asset analog of the 1099-B that traditional brokers send for stock sales. Starting with the 2025 tax year (forms issued in early 2026), centralized crypto brokers — Coinbase, Kraken, Gemini, and most U.S.-licensed lenders — are required to report customers’ digital-asset transactions to both the customer and the IRS. The first wave of forms covers gross proceeds from sales and dispositions; later phases will add cost basis tracking.
The IRS’s Digital Assets information page is the official primary source. Reading the actual form-instructions PDF is worth your time if you have any volume — it lists the seventeen distinct transaction types brokers must classify, including a few that show up on loan accounts even when you never intended a sale.
When a crypto loan does NOT trigger Form 1099-DA
The good news first. Pledging crypto as collateral on a loan is not a disposition under U.S. federal tax law and therefore does not, by itself, generate a 1099-DA reportable event. This is the bedrock principle that makes crypto-backed loans tax-efficient in the first place. We covered the broader framing in how crypto loans help you avoid capital gains tax in 2026 — Form 1099-DA does not change that core treatment.
Specifically, the following events on a typical loan account do not appear on Form 1099-DA:
- Depositing crypto into a lender’s custody as collateral.
- Receiving the loan principal in fiat or stablecoins.
- Making interest payments (which are not gain or loss events).
- Repaying the principal and receiving your collateral back.
If your loan ran a normal life cycle — pledge, borrow, pay interest, repay, withdraw — your lender should not issue a 1099-DA for it at all. That is the clean case.
When a crypto loan DOES trigger a 1099-DA
The complications start when something other than a clean repayment closes the loan. Three common scenarios produce reportable events:
1. Margin liquidation
If your collateral drops below the maintenance LTV and the lender liquidates a portion (or all) of it to satisfy the loan, the IRS treats that liquidation as a sale. The lender sells your BTC or ETH at the market price, applies the proceeds to your debt, and reports the proceeds on a 1099-DA. You then owe capital gains tax on the difference between the liquidation proceeds and your cost basis in that crypto. We walk through the mechanics in detail in avoid liquidation in volatile markets: a guide.
2. Collateral conversion or rebalancing
Some lenders quietly convert your collateral between assets when their internal risk model demands it — converting volatile BTC to a stablecoin during a sharp drawdown, for example. Each conversion is a disposition. Each disposition appears on the 1099-DA. Read your lender’s terms of service for “collateral substitution” or “rehypothecation” language; this is where many borrowers get surprised.
3. In-kind interest payment
If you opt to pay interest in BTC instead of fiat — some lenders give a discount for this — every interest payment is technically a disposition of BTC. Every payment generates a 1099-DA line item. The discount can still be worth it after tax, but you need to model it before opting in.
How to read your 1099-DA when it arrives
The form itself has a few key boxes:
- Box 1a (Description): the digital asset (BTC, ETH, USDC, etc.).
- Box 1b (Date acquired): when the lender records you acquired the asset that was disposed of.
- Box 1c (Date sold or disposed): the liquidation or conversion date.
- Box 1d (Proceeds): gross proceeds in USD.
- Box 1e (Cost basis): your cost basis, if the lender knows it (often blank in the first year).
- Box 4 (Federal income tax withheld): usually zero unless you triggered backup withholding.
If Box 1e (cost basis) is blank, the IRS will treat your basis as zero unless you provide it. That is the worst-case tax outcome. Keep a cost-basis spreadsheet for every BTC or ETH lot you have ever pledged, with date, USD value at acquisition, and source. Most tax-software platforms — TokenTax, Koinly, CoinTracker — import 1099-DA forms and let you reconcile basis from your own records. Use them.
The three mistakes 1099-DA recipients make most often
Across the first wave of 2025-tax-year filings, three errors account for the majority of incorrect returns:
Mistake one. Treating the entire 1099-DA proceeds as taxable income. The form reports gross proceeds, not gain. Your tax owed is on the gain — proceeds minus cost basis. Filers who paste Box 1d into their 1040 without subtracting basis dramatically overpay.
Mistake two. Not reconciling lender-reported basis against personal records. Lenders only know your basis if you bought the crypto on their platform. If you transferred BTC in from a hardware wallet, the lender shows zero basis. You have to fill it in yourself.
Mistake three. Missing the wash-sale workaround that does not apply to crypto. Stock wash-sale rules (no loss harvesting if you rebuy within 30 days) currently do not apply to digital assets. That can be useful for tax-loss harvesting, but Congress has been close to extending wash-sale rules to crypto for two years — check current law before you plan around it.
What to do this tax season
If you held a crypto-backed loan at any point in 2025, three concrete steps:
- Pull your annual statement from your lender. Note any liquidation, conversion, or in-kind interest events.
- Pull your Form 1099-DA when it lands (lenders send by mid-February). Reconcile every line.
- Fill in cost basis from your own records for any line where the lender shows zero or blank.
If everything reconciles to zero — pure pledge, borrow, repay — you owe nothing on the loan and the form is informational only. If you had liquidations or conversions, work through the math (or hand it to a CPA who has crypto experience) before filing.
Frequently asked questions
Does pledging Bitcoin as collateral generate a Form 1099-DA?
No. Pledging crypto as collateral is not a disposition under federal tax law, so no 1099-DA is issued for the pledge itself. Forms are only issued when there is an actual sale, conversion, or other disposition.
What if my lender liquidates part of my collateral during a margin call?
A liquidation is a sale. Your lender will report the gross proceeds on Form 1099-DA, and you owe capital gains tax on the difference between proceeds and your cost basis in the liquidated crypto.
Will I get a 1099-DA from a DeFi loan on Aave or Compound?
For tax year 2025, DeFi protocol reporting is still being implemented. Most non-custodial DeFi protocols do not currently issue 1099-DA. You are still responsible for tracking and reporting any taxable dispositions yourself.
What if Box 1e (cost basis) on my 1099-DA is blank?
You must supply your own cost basis when filing. Use your records of when and at what price you originally acquired the crypto. If you cannot establish basis, the IRS treats it as zero.
Are crypto loan interest payments deductible?
Generally only if the loan proceeds were used for investment or business purposes, subject to the limits of IRC section 163. Personal-use crypto loan interest is not deductible. Consult a tax professional for your specific situation.
