How to Handle a 1099 from an Exchange That Later Went Bankrupt

14 October 2026

If you received a 1099 tax form from an exchange that later collapsed, you still need to report the income or transaction it represents - even if you never actually received the funds. The IRS treats the 1099 as information, not as a final determination of what you owe. You can correct the record when you file, but ignoring the form creates audit risk.

Why the 1099 Still Exists

The exchange generated the 1099 before it failed. The form reports a taxable event that occurred in a prior tax year: a sale, a trade, or income such as staking rewards or interest. The exchange's subsequent bankruptcy does not retroactively undo that event. The IRS expects you to report the transaction, but it also expects you to report only what you actually received or controlled.

The complication is that the exchange may have reported an amount you never withdrew, or may have reported a sale that happened inside the platform but from which you never got the cash. In some cases, the exchange reported income (like staking rewards) that existed only as a ledger entry and was later lost in the collapse.

Step 1: Confirm the 1099 Matches Your Records

Before you file, compare the 1099 against your own transaction history - ideally records you exported before the exchange froze withdrawals. If you do not have your own records, see the site's guide on proving holdings after an exchange deletes history.

Check three things: - The type of income reported. Was it a capital gain from a trade, or ordinary income from staking or lending? - The dollar amount. Does it match what you expected, or does it include phantom income from activities you did not authorize? - The cost basis (if reported). Was the exchange using a method (FIFO, LIFO, specific ID) that matches your own?

If the 1099 is correct, report the transaction normally. The fact that the exchange later failed does not change your tax obligation for the year the event occurred.

Step 2: If the 1099 Is Wrong, File Correctly

If the 1099 reports income you never received - for example, staking rewards that were credited but then frozen before you could withdraw them - you have two choices:

• Report the amount shown on the 1099, then claim a loss or deduction in the same year. This is the most defensible approach if the amount is small. You report the income, then immediately report a loss for the same amount due to the exchange's failure. The loss would be a short-term capital loss or a theft loss, depending on your jurisdiction and the circumstances.
• Report the correct amount and attach an explanation. You file the return with the correct figure, and include a statement explaining that the 1099 is incorrect because the income was never realized or was lost before you could access it. This is riskier - the IRS may flag the mismatch and ask for documentation.

In either case, keep all evidence: the 1099, your transaction history, the exchange's bankruptcy filing, and any claims portal documentation showing your account was frozen.

Step 3: Handle the Loss Separately

The loss of funds on the exchange is a separate tax event from the income reported on the 1099. You cannot simply net them. The loss occurs in the year the exchange collapsed and the funds became unrecoverable, which is likely a different tax year than the year the 1099 income was earned.

For the loss itself: - If the exchange is in bankruptcy, you may not be able to claim a loss until the bankruptcy concludes and you know the final recovery amount. - If the exchange is clearly defunct with no recovery expected, you may be able to claim a theft loss or a capital loss in the year of the collapse. - The rules vary by jurisdiction. Consult a tax professional who handles cryptocurrency.

Step 4: If You Cannot Access the 1099

If the exchange collapsed before issuing your 1099, you are still responsible for reporting the transactions. Use your own records to reconstruct the activity. If you have no records, you may need to estimate based on what you can recover from blockchain explorers, email confirmations, or the claims portal.

When to Amend a Prior Year Return

If you already filed your return for the year the 1099 covers, and you later discover the 1099 was wrong, you may need to file an amended return. This is more likely if you reported the 1099 amount as income and later realized you never received it. Amending is straightforward but time-sensitive - most jurisdictions have a three-year window from the original filing deadline.

Practical Advice

• Do not ignore the 1099. The IRS receives a copy and will expect a matching return.
• Do not assume bankruptcy wipes out the tax obligation. It does not.
• Keep all documentation indefinitely. Exchange bankruptcies can take years to resolve, and tax authorities may ask questions long after the event.
• If the amount is significant, pay a tax professional who understands both cryptocurrency and insolvency. This is not a DIY situation for large sums.

The core principle: the 1099 reports what the exchange said happened. Your tax return reports what actually happened. If those differ, you need evidence and a clear explanation - but you do not have to accept a wrong 1099 as final.
