When a cryptocurrency exchange files for bankruptcy, you lose access to your assets. But the tax consequences do not disappear. You may still owe taxes on prior gains. You may have losses you can claim. You may receive partial distributions that create new taxable events. The intersection of bankruptcy law and crypto tax law creates a situation that requires careful handling.

When Can You Claim the Loss

A theft or casualty loss on investment property is claimed in the year the loss becomes identifiable as a closed and completed transaction. For exchange bankruptcies, this is generally the year the exchange files for bankruptcy or the year it becomes clear that recovery will be zero or partial. The IRS has not issued specific guidance on the timing for crypto exchange bankruptcies, creating uncertainty that requires professional judgment.

Character of the Loss

If your crypto held on the exchange was a capital asset (investment property), the loss is a capital loss. Capital losses offset capital gains dollar for dollar and offset up to $3,000 of ordinary income per year, with unused losses carrying forward. If you can establish that the exchange engaged in fraud, you may be able to treat the loss as a theft loss — which may provide more favorable treatment depending on your other income and deductions.

Basis in Lost Crypto

Your loss equals your adjusted basis in the crypto that was on the exchange — not the fair market value at the time of loss. If you bought Bitcoin at $5,000 and it was worth $50,000 when the exchange collapsed, your loss deduction is limited to $5,000 (your basis), not $50,000 (the value). The unrealized appreciation was never taxed and therefore cannot be deducted.

Bankruptcy Distributions

If you receive a partial distribution from the bankruptcy estate — in crypto, fiat, or equity in a reorganized entity — that distribution reduces your loss. If the distribution exceeds your basis, the excess is a gain. Track all distributions carefully and report them in the year received.

Prior-Year Obligations

The exchange bankruptcy does not eliminate taxes owed on gains realized before the collapse. If you traded profitably on the exchange before it failed, those gains are still taxable. The subsequent loss of assets on the exchange is a separate event. Attorney Darrin T.
