Cryptocurrency investors in the United States have long had to consider taxes when selling, exchanging or otherwise disposing of digital assets. But reporting by brokers is becoming more structured, making accurate transaction records increasingly important.
For the 2026 tax year, investors should understand the role of Form 1099-DA and why a broker's report may not contain every detail needed for a complete tax return.
Digital Assets Can Create Taxable Events
Buying cryptocurrency with U.S. dollars and simply holding it generally does not create a taxable gain or loss by itself. A later sale, exchange or other taxable disposition can create a reporting obligation.
For example, an investor who buys a digital asset and later sells it for more than the purchase cost may have a capital gain. Selling for less may produce a capital loss, subject to the applicable tax rules.
Using one cryptocurrency to acquire another can also have tax consequences. Investors should not assume that a transaction is tax-free merely because no dollars were deposited into a bank account.
Other activities, including receiving digital assets as compensation or rewards, may have different tax treatment.
What Form 1099-DA Does
The IRS created Form 1099-DA for reporting certain digital asset transactions by brokers. The form is part of the federal government's effort to improve information reporting for digital asset activity.
For transactions after 2025, broker reporting requirements apply under the relevant rules. The form can report sales and exchanges, but the information available to the broker may vary depending on the transaction and whether the asset is treated as a covered or noncovered asset for reporting purposes.
The IRS instructions explain how brokers complete the form and what information must be provided.
Why the Form May Not Tell the Whole Story
A 1099-DA is an information document, not a complete tax return. Investors may have acquired assets through a different exchange, transferred them between wallets or purchased them years before the reporting broker held them.
A broker may not know the original purchase cost, known as the cost basis, for an asset transferred into its platform. That can leave the investor responsible for reconstructing the relevant records.
Investors should keep dates, amounts, transaction IDs, fees, wallet transfers and purchase records. They should also distinguish a transfer between wallets they control from a sale or exchange to another party.
Recordkeeping Across Multiple Platforms
Someone who uses several exchanges or wallets may have a fragmented transaction history. Downloading account statements and transaction records regularly can make tax preparation easier.
A useful record should identify the asset, quantity, date, value in U.S. dollars and the nature of the transaction. Fees and the original cost basis may also be relevant.
Investors should avoid relying solely on a year-end summary if they have moved assets between services or used decentralized platforms.
Reporting Responsibilities Remain With the Taxpayer
Information reporting by brokers does not eliminate the taxpayer's responsibility to report taxable transactions correctly. If a form contains an error, investors should contact the broker and retain supporting documentation.
Tax treatment can differ according to how the asset was acquired, how it was used and the nature of the transaction. Investors with complicated activity may need professional tax assistance.
The Bottom Line
Digital asset reporting is becoming more formal, but cryptocurrency investors still need their own accurate records. Form 1099-DA can provide useful transaction information, yet it may not establish the complete cost basis or capture every activity. Maintaining records throughout the year is more reliable than attempting to reconstruct a full crypto history at tax time.
