Terra LUNA, LUNC and UST taxes: 2026 US guide

The 2022 Terra collapse did not automatically create a deductible federal tax loss for every holder. An investor generally realizes a capital loss when LUNA, LUNC, UST or USTC is sold, exchanged or otherwise disposed of. Merely holding a token that still trades above zero does not close the transaction. Worthlessness and abandonment rules are narrower, and a non-security digital-asset loss can be a permanently disallowed miscellaneous itemized deduction for an individual.

First identify LUNA, LUNC, UST and USTC correctly

After the May 2022 events, the original network and tokens became commonly known as Terra Classic, LUNC and USTC, while a new network used LUNA. Tax records must preserve the actual asset and chain. Renaming a ticker is not itself a sale, but a migration, exchange or distribution can create a separate tax question.

US federal tax law treats digital assets as property. Buying and holding are generally not realization events. Selling, swapping for another token, spending or exchanging an asset usually creates gain or loss measured in US dollars.

How a Terra crash loss becomes a capital loss

An investor who sells LUNC or USTC for cash, swaps it for another digital asset or otherwise completes a taxable disposition calculates proceeds minus adjusted basis. A near-zero sale can realize a large capital loss. The transaction must be genuine, completed and supported by the exchange confirmation or blockchain record.

For example, assume an investor bought UST for $20,000 and later sold all units for $1,200 after the depeg, paying a $20 selling fee. If the adjusted amount realized is $1,180, the capital loss is $18,820. The holding period determines whether it is short term or long term.

Capital losses first offset capital gains. If losses exceed gains, an individual may generally deduct up to $3,000 of net capital loss against other income, or $1,500 when married filing separately, and carry the remaining loss forward. The US crypto-loss guide explains netting and carryovers.

Holding a nearly worthless token is not the same as selling it

IRS Chief Counsel Advice 202302011 addresses an individual who held cryptocurrency that retained some value and continued trading. It states that a mere decline in value does not create a deductible loss; an affirmative step such as a sale or exchange is generally needed to close the transaction. Most cryptocurrency is also not a “security” within the narrow definition of section 165(g), so the automatic worthless-security sale rule does not apply merely because a token collapsed.

Worthlessness requires an identifiable event and complete lack of current and potential value. Abandonment requires intent plus an affirmative act permanently surrendering all rights. Retaining the private keys and the ability to sell or transfer the token is inconsistent with abandonment. Sending tokens to a burn address solely for tax purposes raises additional substance, valuation and reporting questions and should not be treated as a guaranteed capital-loss strategy.

Even where a non-security digital asset is truly worthless or abandoned, the Chief Counsel memorandum analyzes the resulting section 165 loss for an individual as a miscellaneous itemized deduction rather than a capital loss. Public Law 119-21 made the section 67 suspension permanent for taxable years beginning after 2017, so such miscellaneous itemized deductions generally are not allowed to individuals in 2026. The memorandum is not precedent and each case is fact-specific, but it shows why an actual arm's-length sale or exchange is materially different from merely writing a token down to zero.

• Still held and traded: no realized loss merely from the lower market price.
• Actually sold or exchanged: investor generally reports a capital gain or loss.
• Claimed worthless: complete worthlessness and an identifiable event must be proved.
• Claimed abandoned: intent and an affirmative surrender of all rights are required.
• Business inventory or business asset: may follow different character rules.

Terra 2.0 LUNA distribution: avoid a blanket answer

Some LUNC and UST holders received new-network LUNA under the Terra 2.0 allocation. The IRS has not issued a Terra-specific revenue ruling. Revenue Ruling 2019-24 expressly addresses a hard fork followed by an airdrop, with income when the recipient has dominion and control. The Terra restructuring and allocation must be tested against its actual technical and legal facts rather than automatically labeled a textbook hard fork.

A conservative report should show the distribution separately, record when the new LUNA became transferable, capture its fair market value, and flag the tax classification for confirmation. If an amount is included in ordinary income, that amount generally becomes basis in the new tokens. If the event is instead treated as a nontaxable continuation or another form of property reorganization, basis allocation may be different.

1. Identify the original eligible wallet and snapshot category.
2. Separate immediately available LUNA from vested allocations.
3. Record the first time each tranche could be sold or transferred.
4. Document market availability and a supportable USD value.
5. Do not merge new LUNA lots with LUNC basis.
6. Reconcile every later sale with the confirmed treatment.

The US airdrop guide explains dominion and control and the limited scope of the hard-fork ruling.

Anchor Protocol rewards, deposits and frozen claims

Anchor and other Terra protocols created multiple event types: deposits, receipt tokens, yield accrual, withdrawals, liquidations and governance rewards. “Interest” displayed in an interface is not enough to determine the tax event. A taxpayer needs to know whether property was exchanged for a new token, whether a separate reward was received and when it became transferable.

Ordinary income generally arises when a taxpayer receives a digital asset as a reward and has dominion and control. If an account or protocol was frozen before accrued rewards became transferable, IRS Chief Counsel Advice 202444009 distinguishes credited, controllable rewards from amounts not yet available. Principal returned is not additional income, while a loss on a separate claim may follow rules different from a token sale.

• Keep aUST or other receipt-token movements linked to the original deposit.
• Separate principal, yield, incentive tokens and fees.
• Record liquidation proceeds and discharged debt independently.
• Do not count interface accruals that were never controlled without reviewing the contract.
• Flag frozen platform claims and bankruptcy recoveries for separate analysis.

Where Terra transactions appear on the return

Investor sales and swaps generally appear by lot on Form 8949 and roll to Schedule D. Nonbusiness ordinary digital-asset income can appear on Form 1040 or Schedule 1 as applicable. Business rewards and activities may require Schedule C and self-employment analysis. A Form 1099-DA does not replace self-custody records or prove basis.

1. Export all pre-collapse and post-collapse exchange records.
2. Recover original cost basis from transfers and old wallets.
3. Separate LUNC, USTC and new LUNA identifiers.
4. List actual sale or swap proceeds, even when tiny.
5. Preserve short-term versus long-term holding periods.
6. Carry unused capital losses forward correctly.
7. Keep unresolved airdrop and DeFi classifications in a review schedule.
