Why does my 1099-DA say short-term when I held it long-term?

Usually because the broker measured the holding period from what it could see, and it could not see the acquisition. A broker determines short-term or long-term from events in its own account. The 2026 Instructions for Form 1099-DA say brokers are "not required to consider other transactions, elections, or events occurring outside the account …" when determining short-term or long-term. When units were transferred in, the instructions let the broker treat them as acquired "as of the date and time of the transfer" unless it takes the customer's acquisition information into account, and even then only for picking lots. The tax rule is different. IRS FAQ A81 treats a move between the client's own wallets or accounts as non-taxable. The FAQs do not address holding period directly; because there is no sale or exchange, our reading is that the holding period of the same units continues. If a transfer-in gets treated as a new acquisition, by the broker or in the books, the reported term can differ from the holding period for tax purposes. The fix starts with classifying the transfer-in. Unclear ones go to review. CryptoTaxEdge classifies. It does not compute holding period or basis.

What the IRS says

The holding period rule. IRC 1222(1) defines short-term capital gain as gain "from the sale or exchange of a capital asset held for not more than 1 year," and 1222(3) defines long-term capital gain as gain from a capital asset "held for more than 1 year." IRS FAQ A50 on digital asset transactions says the holding period "begins on the day after you acquired the digital assets and ends on the day you sell or exchange them."

Exchanges versus transfers. A transfer to the client's own wallet is not an exchange at all. IRS FAQ A81 says that if you transfer digital assets "from a wallet, address, or account belonging to you, to another wallet, address, or account that also belongs to you, then the transfer is a non-taxable event," except for assets used to pay transfer costs. A81 does not mention holding period; that the holding period continues is our reading, not an IRS statement. By contrast, FAQ A74 says that for digital assets acquired in an exchange for other digital assets "differing materially in kind or extent," the holding period "begins the day after they are received."

What the broker reports. The 2026 Instructions for Form 1099-DA say, for box 6, that a broker reporting a covered security, or a noncovered one where it chooses to complete box 6, must "determine whether the gain or loss is short-term or long-term under section 1222," and that "You are not required to consider other transactions, elections, or events occurring outside the account when determining whether the gain or loss on the sale is short-term or long-term." The 2025 instructions carry the same sentence. On transferred-in units, the identification rules say: "If you do not take customer-provided acquisition information into account for that purpose, treat digital assets transferred into the customer's account as acquired as of the date and time of the transfer." The 2026 instructions add: "Under current law, brokers may use customer-provided acquisition information solely for lot-selection purposes and not for reporting basis or acquisition dates." The identification paragraph cites Regulations section 1.6045-1(d)(2)(ii)(B)(4).

The boxes to read. Box 12a gives "the number of units" transferred into a custodial account and box 12b "the date of such transfer-in." Box 9 marks a noncovered security, and with it checked the broker does not have to complete box 1d or box 6. Box 8 shows the broker relied on customer-provided acquisition information "to identify which digital assets of a type were sold." Code Y means the broker "cannot determine whether the recipient should check box H or box K on Form 8949 because the holding period is unknown." For Form 8949 handling of code Y and term corrections, see How do I report Form 1099-DA on Form 8949 and Schedule D?.

Why the term flips

Three patterns cover most cases:

1. Transfer-in measured from the deposit. The client bought in self-custody or on another platform, moved the units in, and sold within a year of the deposit but more than a year after the purchase. The broker's view starts at box 12b.
2. Transfer-in booked as a new acquisition in the client's own records. The deposit was imported as a buy at market value. The broker may even be right; the books are what restarted the clock.
3. Lot selection. The client held long-term and short-term lots of the same asset, and the units identified as sold (or sold under the default order) were the short-term ones. Lot identification is covered in What are covered vs noncovered digital assets on Form 1099-DA for 2026?; we do not repeat it here.

Patterns 1 and 2 both turn on one fact: was the transfer-in a movement of the client's own units, or a new acquisition? That is a classification question, answered at the hash. For why a self-transfer is not taxable, see Is transferring crypto between your own wallets taxable?.

Where it is genuinely unsettled

A wrap or similar step before the transfer-in. Suppose the client wrapped an asset one-to-one, then deposited the wrapped token, and the broker sold it. Whether the long-term holding period of the underlying asset carries depends on whether the wrap was a disposition. Practitioners hold two positions:

• Not a disposition. The wrap is a one-to-one representation of the same asset, so basis and holding period carry and the sale can be long-term.
• An exchange. The wrapped token is a different asset. Under FAQ A74, for assets "differing materially in kind or extent," the holding period begins the day after receipt, so the sale may be short-term.

The IRS sources we fetched on October 20, 2026 do not address the tax treatment of wrapping specifically; under Notice 2024-57, brokers also need not report wrapping transactions until further guidance, so a wrap step may not appear on any form. The CTE Standard marks wrap as a grey area: the house default is non-taxable with basis carried, the disposition view is on the record, and a firm can elect it only by sending a policy. Which position the firm takes is its call.

Worked example

A client bought 2.00000000 ETH with USDC in a self-custody wallet in March 2024. In February 2026 the client sent the ETH to a U.S. custodial exchange and sold it there in November 2026. The 2026 Form 1099-DA shows box 9 checked, box 12a 2 ETH, box 12b with the February 2026 date, and box 6 short-term, code H.

The acquisition hash serves as swap (house treatment disposal): USDC out, ETH in, March 2024. It gives the firm a dated on-chain acquisition.

The transfer-in hash serves as category transfer with needs_review: true and taxable: null, because the receiving deposit address is not verified on-chain as the client's own (Standard GAP-1). The firm matches the deposit to the client's exchange account statement and keeps that evidence in the workpapers. That human confirmation settles it as a self-transfer, not an acquisition; the served record stays a review-routed transfer.

Result. The firm's records show a March 2024 acquisition, so, assuming the wallet held only that lot, the term from records is long-term. The broker's short-term box 6 reflects the transfer-in date. How the row goes on Form 8949 is the preparer's decision, using the mechanics on the Form 8949 page.

A second lot that stays open. The same client also deposited 0.50000000 ETH from an address the client cannot identify. That hash stays needs_review. Without evidence that the source was the client's own wallet, the firm has no acquisition date to rely on, and the row stays on the review list.

How CryptoTaxEdge fits

Classification is a hash in, a record out. POST https://app.cryptotaxedge.com/v1/classify with { "chain", "hash" }. One category, one treatment from the closed enum (disposal, income, non_taxable, expense, needs_review), confidence 0 to 100 as a routing signal, needs_review: true and taxable: null when a treatment cannot be honestly asserted. Confidence is not an accuracy percentage.

For a term mismatch, the hashes that matter are the transfer-in and the original acquisition. A one-way transfer whose counterparty is not verified as the client's own wallet serves as category transfer with needs_review and taxable: null (Standard GAP-1); verified self-transfers serve non_taxable. A review-flagged transfer-in is the signal not to rely on the deposit date or the purchase date until a human settles ownership. See What does needs_review mean?.

What CryptoTaxEdge does not do on this page

• We do not compute holding period, basis, gain, or loss.
• We do not decide whether the broker's box 6 is right, or choose Form 8949 boxes or codes.
• We do not identify lots or make specific identifications.
• We do not contact issuers or request corrected forms.
• We do not connect to wallets or take custody. Hash in; category, treatment, confidence, and review flag out.
