Form 1099-DA and Solana: what it covers and what it does not

Software, not tax, legal or investment advice. Estimates may be wrong. Verify with a tax professional.

Form 1099-DA is a broker information return, not a complete wallet tax report. For a Solana user, it may cover some dispositions while leaving acquisition history and self-custody activity to reconstruct. This guide covers US federal reporting for individual holders of capital assets reading in 2026.

Keep the transaction year separate from the year a statement arrives. A form received in 2026 can describe 2025 activity. The 2026 version discussed below concerns 2026 transactions; use the version and instructions applicable to the statement you are reconciling.

What began in 2025 and changes in 2026?

IRS broker reporting guidance explains the phase-in: brokers (including custodial platforms) report gross proceeds for transactions effected from January 1, 2025, while basis reporting begins for certain transactions from January 1, 2026. This does not mean every 2026 disposition arrives with reported basis.

The 2026 Form 1099-DA instructions define covered assets by both acquisition circumstances and custody. Generally, the asset must be acquired after 2025 in the broker's custodial account through a qualifying acquisition and remain there until disposition. Older assets and transferred-in assets are noncovered under those instructions.

A basis gap therefore has several possible explanations. It may reflect the reporting category rather than a problem with your own documentation. Preserve the statement as issued and prepare a separate reconciliation instead of filling every blank with zero.

Read the form as a set of evidence fields

The 2026 Form 1099-DA includes asset identity, units, acquisition and disposition dates, proceeds, basis, and reporting indicators. Some fields are conditional. The presence of a field on the printed form does not establish that the broker must populate it for every asset.

Field on the 2026 form	Review question
1c, number of units	Does this match the disposition quantity?
1f, proceeds	Which ledger event or events support the amount?
1g, cost or other basis	Is an amount present and supported?
2, basis reported to IRS	Was basis actually reported, or merely provided to you?
9, noncovered security	Does the acquisition history explain this category?
12a and 12b, transfer-in information	Can you trace the units to earlier records?

The instructions for box 1g distinguish an omitted basis amount from a genuinely zero basis. The form's use of “covered” and “noncovered” is a reporting classification; do not use those labels as a shortcut for deciding every other legal question about a token.

Self-custody activity may not appear

The custodial broker rules described in the IRS guidance do not cover every noncustodial service. The separate December 2024 DeFi broker rule was removed after congressional disapproval, as recorded in IRS Bulletin 2025-31: DeFi rule removal. Its removal does not eliminate the taxpayer's own reporting obligations.

We have not verified the reporting status of every Jupiter service, Solana interface, intermediary, or route. Do not assume that a platform name guarantees a form, or guarantees that none will be issued. Record what service was used and whether assets were held in custody, then ask a tax professional about an uncertain arrangement.

The 2025 Form 8949 instructions tell you to include transactions even if you did not receive a Form 1099-B, 1099-DA or 1099-S, and the IRS digital asset FAQs (FAQs 100-101) say the same for transactions a broker does not report to you. Keep a ledger of self-custody dispositions alongside broker records. Also keep income receipts separately identified; a proceeds statement cannot by itself establish the income treatment of every reward or airdrop.

Missing basis does not turn proceeds into profit

Suppose Casey's statement reports $1,200 of proceeds with no basis reported. Casey's acquisition records support $900 basis for the disposed units. Assume capital-asset treatment, no fees, and no other adjustments. The working gain is $300, not $1,200.

That result depends on matching the correct units to the documented acquisition. A $900 acquisition somewhere in the wallet history is not enough if it belongs to a different lot or has already been used for an earlier disposition. Preserve the acquisition record and any transfers connecting it to the broker.

If the evidence is incomplete, label the basis unresolved and discuss reconstruction with your preparer. Do not invent a cost from the deposit-date price merely to make the calculation possible. Keep evidence of attempted retrievals and any assumptions the reviewer ultimately accepts.

Match each event before combining totals

Start with a reconciliation sheet containing the statement reference, wallet or account event, quantity, proceeds, supported basis, and explanation of differences. Include both matched entries and unmatched entries. Annual totals alone can hide a missing trade offset by a duplicate.

One disposition can appear in a broker export, a wallet import, and the information return. Those are three records to compare, not automatically three transactions. Conversely, an aggregate statement amount may require several ledger entries to explain it. Preserve the detailed records rather than forcing a one-to-one match where the statement groups transactions.

If a statement appears incorrect, retain it and any corrected version, along with correspondence seeking correction. Have your preparer reconcile the final reporting position to the version used for filing. A manual change should leave an explanation that remains understandable after the import session ends.

Carry the reconciliation into the return

The 2025 Form 8949 instructions use digital-asset categories G/H/I for short-term transactions and J/K/L for long-term transactions. The categories distinguish basis reported to the IRS, basis not reported, and transactions without the specified information returns. Use the actual statement indicators, not a guess based on whether the basis field looks complete.

Those instructions also describe corrections when reported basis is wrong and exceptions permitting certain summary reporting. Do not assume that every annual wallet total qualifies. For 2026 returns, check the applicable final Form 8949 instructions rather than assuming the 2025 presentation is unchanged.

Finish with the statement reconciliation, detailed lot ledger, receipt-income records, and unresolved questions together. Form 1099-DA helps compare reported proceeds with your records; the complete history still supplies the context needed to prepare the return.
