Form 1099-B and Cryptocurrency: The New Era of Digital Asset Tax Reporting

The arrival of Form 1099-DA in 2025 fundamentally reshapes how cryptocurrency investors receive tax documents. For years, a persistent question echoed through crypto tax discussions: does Form 1099-B apply to digital asset trades? The answer shifts dramatically as the IRS rolls out dedicated digital asset reporting infrastructure. Understanding the distinction between 1099-B and 1099-DA, the effective dates for reporting requirements, and the practical implications for tax filing separates informed investors from those caught off guard. Form 1099-B and Cryptocurrency.

This article examines the complete landscape of IRS information reporting for cryptocurrency transactions. You will learn which forms apply to which activities, how brokers must report gross proceeds and cost basis, what the new transitional relief means for 2025 filings, and how to reconcile multiple tax documents with your actual transaction history. The analysis includes mathematical examples, side-by-side form comparisons, and practical strategies for avoiding common filing errors.

The Role of Form 1099-B and Cryptocurrency Traditional Finance

Form 1099-B, Proceeds From Broker and Barter Exchange Transactions, has served as the primary information return for securities sales since the 1980s. Brokers file this form with the IRS and furnish copies to customers to report the gross proceeds from sales of stocks, bonds, commodities, and certain derivatives.

What Form 1099-B Typically Reports

A standard Form 1099-B includes several data points critical for calculating capital gains and losses. The form lists the date of acquisition, date of sale or disposition, gross proceeds from the sale, cost basis of the asset sold, and the resulting gain or loss. For covered securities—those acquired after specific effective dates—the broker must report basis information to the IRS.

The form also indicates whether the gain or loss qualifies as short-term or long-term based on the holding period. Short-term dispositions appear in Box A or Box B depending on whether the broker reported basis. Long-term dispositions appear in Box C or Box D. The form may include adjustments for wash sales, gifts, or other special circumstances.

Why Cryptocurrency Did Not Cleanly Fit 1099-B

Before 2025, the IRS did not mandate specific information reporting for cryptocurrency transactions. While the agency classified digital assets as property under Notice 2014-21, no parallel reporting regime required brokers to file information returns for crypto sales. Some exchanges voluntarily issued Form 1099-B for certain products—particularly Bitcoin futures traded on regulated exchanges like the CME Group. These futures contracts qualified as traditional securities under CFTC jurisdiction, so the 1099-B reporting applied naturally.

For spot cryptocurrency transactions, the legal uncertainty centered on whether crypto exchanges qualified as brokers under Section 6045 of the Internal Revenue Code. A broker generally includes any person who regularly effects transactions for others in the ordinary course of a trade or business. Crypto exchanges clearly fit this definition, but the IRS had not issued regulations specifying how digital asset brokers should comply with information reporting requirements. This gap meant most crypto investors received no Form 1099-B from exchanges like Coinbase or Kraken for spot trades, leaving taxpayers solely responsible for tracking and reporting their own gains.

The Arrival of Form 1099-DA

The Infrastructure Investment and Jobs Act of 2021 closed the reporting gap. Section 80603 of the Act amended Section 6045 to explicitly include digital asset brokers within the information reporting framework. The legislation required the IRS to issue regulations specifying how brokers must report digital asset dispositions.

Final Regulations Published July 2024

The IRS released final digital asset reporting regulations in the Federal Register on July 9, 2024. The regulations apply to transactions undertaken in 2025 and thereafter, with actual reporting to the IRS beginning in 2026. The centerpiece of this new regime is Form 1099-DA, Digital Asset Proceeds From Broker Transactions.

Form 1099-DA mirrors the structure of Form 1099-B but with specifications tailored to digital assets. The form includes fields for the type of digital asset (BTC, ETH, SOL, etc.), the quantity sold or disposed, the date of acquisition, the date of disposition, gross proceeds, cost basis, and the resulting gain or loss. The design assumes brokers can access the necessary information from their internal records and customer account data.

Phased Implementation Schedule

The IRS phased the reporting requirements to give brokers time to build compliant systems. Gross proceeds reporting began January 1, 2025. For the 2025 tax year, brokers must track and report the gross proceeds from digital asset sales and exchanges, but they are not required to report basis information. This means Form 1099-DA for 2025 transactions will include the date of sale, quantity sold, and gross proceeds, but not the acquisition date or cost basis.

Cost basis reporting begins January 1, 2026, for transactions occurring in the 2026 tax year. Starting with 2026 activity, brokers must track and report cost basis in addition to gross proceeds on digital asset sales. The 2026 Form 1099-DA will include full information comparable to what traditional brokers provide on Form 1099-B for covered securities.

When Form 1099-B Still Applies to Cryptocurrency

Despite the introduction of Form 1099-DA, certain cryptocurrency-related transactions continue to generate Form 1099-B. Investors must understand these edge cases to avoid confusion when reconciling multiple tax documents.

Bitcoin Futures and Crypto Derivatives

Cryptocurrency futures contracts traded on CFTC-regulated exchanges like the CME Group fall outside the scope of Form 1099-DA. These products are traditional securities, not spot digital assets. The exchanges will continue issuing Form 1099-B to report proceeds, basis, and gain or loss from futures positions. An investor holding Bitcoin futures contracts receives a 1099-B from the futures broker, not a 1099-DA.

Similarly, options on crypto futures, crypto ETFs (such as BITO, a Bitcoin futures ETF), and other regulated derivative products generate Form 1099-B. The underlying asset may be Bitcoin, but the investment vehicle is a traditional security subject to existing reporting rules.

Tokenized Securities

The IRS clarified that tokenized securities—digital representations of traditional securities—must be reported on Form 1099-DA starting in 2025, effectively replacing Form 1099-B for these assets. This means a tokenized stock or bond will generate a 1099-DA, not a 1099-B, even though the underlying instrument resembles a traditional security.

The distinction matters for investors who hold tokenized real-world assets. A tokenized US Treasury bond creates a digital asset disposition reportable on 1099-DA, while a traditional Treasury bond held through a conventional brokerage generates Form 1099-B.

Barter Exchange Transactions

Form 1099-B also covers barter exchange transactions under the original statutory language. A cryptocurrency investor who barters digital assets directly for goods or services through a barter exchange platform may receive Form 1099-B reporting the fair market value of the barter transaction. However, most crypto-for-goods transactions occur outside barter exchange platforms and do not generate any information return, leaving the taxpayer responsible for self-reporting.

Side-by-Side Comparison: 1099-B vs. 1099-DA

Understanding the differences between these two forms helps investors anticipate what documents they will receive and how to use them for tax preparation.

What Changes for Tax Year 2025

For transactions occurring in calendar year 2025, brokers must furnish Form 1099-DA to customers by February 17, 2026, and file with the IRS by March 31, 2026. The 2025 Form 1099-DA will include only gross proceeds, date of sale, and quantity sold. The form will not include acquisition dates or cost basis.

This partial reporting creates a compliance challenge. Taxpayers must still calculate gain or loss on each disposition using their own records of acquisition date and cost basis. The gross proceeds reported on Form 1099-DA provide one input to the gain calculation, but taxpayers must supply the other inputs from personal transaction logs.

The Digital Asset Equivalent of 1099-B

Industry professionals describe Form 1099-DA as the digital asset equivalent of Form 1099-B. Like the 1099-B, it reports proceeds from sales and exchanges and sends that information to both the taxpayer and the IRS. The issuance of Form 1099-DA does not change a transaction‘s taxability—it merely adds a reporting mechanism that previously did not exist for spot digital assets.

Understanding the 2025 Transitional Relief Framework

The IRS recognized that brokers and taxpayers need time to adapt to the new reporting requirements. Several relief provisions ease the transition during 2025 and early 2026.

Notice 2025-33 Extends Relief Through 2027

In June 2025, the IRS released Notice 2025-33, extending transitional relief for digital asset brokers. The relief, originally provided in Notice 2024-56, applies to brokers that must file Form 1099-DA under Section 6045 and to backup withholding under Section 3406. The extension gives brokers additional time to build compliant systems while maintaining reporting obligations for gross proceeds.

The IRS has not changed the effective date for gross proceeds reporting. Brokers must still track gross proceeds for 2025 transactions and file Form 1099-DA in 2026. The extension primarily relates to specific reporting details and backup withholding requirements, not the core obligation to report proceeds.

Notice 2025-7 and Adequate Identification Relief

Notice 2025-7 provides temporary relief for taxpayers who want to identify specific digital asset units to be sold from holdings in a broker‘s custody. The relief applies during the 2025 calendar year and addresses a practical problem: many brokers’ systems lack the technological capability to accept taxpayer instructions for specific identification of which units to sell.

Under the final regulations effective January 1, 2025, taxpayers must adequately identify to their custodial broker which digital asset unit they are selling. The broker must then report the basis of that specific unit. Notice 2025-7 allows taxpayers to use alternative methods for making adequate identification during the relief period.

The alternative methods include:

• Using a written standing order on file with the broker before the sale
• Designating the units to be sold through a separate written confirmation after the sale but before settlement
• Relying on the broker‘s default method if the taxpayer has not provided instructions

This relief expires December 31, 2025. For 2026 transactions, taxpayers must use the standard identification procedures.

Revenue Procedure 2024-28 Safe Harbor for Basis Allocation

Revenue Procedure 2024-28 addresses a fundamental change in how taxpayers must track cost basis. Starting January 1, 2025, taxpayers may no longer track the basis of digital assets as if they were held in a single account or address—a practice known as the universal method. Instead, taxpayers must track basis on a per-wallet or per-account basis.

The safe harbor allows taxpayers to allocate unused basis of digital assets held as of January 1, 2025, across their various wallets or accounts. Taxpayers can rely on this safe harbor to make a reasonable allocation of digital asset units of unused tax basis to a wallet. Allocation methods include specific unit allocation—assigning basis to individual digital asset units—and global allocation using a written rule to allocate basis across wallets.

The transition to per-wallet accounting represents a significant operational change for crypto investors. Those who previously used portfolio tracking software that aggregated all holdings without wallet distinctions must now separate their basis across each wallet and exchange account.

Other Tax Forms Cryptocurrency Investors Receive

Form 1099-DA covers dispositions, but other activities generate different information returns. A complete picture of crypto tax reporting includes several form types.

Form 1099-MISC for Staking and Airdrops

When you stake cryptocurrency and receive rewards, or when you receive airdropped tokens, you have taxable income. The value of the rewards or airdropped tokens at the time of receipt constitutes ordinary income reportable on your tax return.

If the total value of staking or airdrop rewards from a single payer exceeds $600 in a tax year, the payer must issue Form 1099-MISC. The form reports the amount of income in Box 3, Other Income. Even if you earn less than $600, you must still report the income on your return, though you may not receive a Form 1099-MISC.

For tax year 2025, exchanges must issue Form 1099-MISC for staking rewards and airdrops exceeding $600. This reporting obligation operates independently of Form 1099-DA. An active crypto investor might receive both forms from the same exchange—1099-DA for dispositions and 1099-MISC for staking income.

Form 1099-INT and Form 1099-MISC for Interest and Rewards

Some platforms offer interest-bearing accounts for cryptocurrency deposits. Interest earned on these accounts generates taxable income reportable on Form 1099-INT if the amount exceeds $10. The same form applies to interest paid on USD balances held on crypto exchanges.

Platform promotions, referral bonuses, and other rewards also generate taxable income. If these rewards exceed $600, the payer issues Form 1099-MISC. If under $600, the taxpayer must still report the income but may not receive an information return.

Form 1099-K for Payment Processing

Crypto payment processors like BitPay and Coinbase Commerce issue Form 1099-K, Payment Card and Third-Party Network Transactions, to merchants who accept cryptocurrency for goods or services. The form reports gross payment volume processed through the platform.

The reporting threshold for Form 1099-K changed for tax year 2025. Third-party settlement organizations must report transactions exceeding $600 in aggregate for the year, down from the previous $20,000 threshold. This change affects many small businesses and freelancers who accept cryptocurrency payments.

Practical Examples with Calculations

Concrete examples illustrate how the new reporting regime affects tax calculations.

Example 1: Selling Bitcoin with Partial 1099-DA Reporting

An investor buys 0.5 Bitcoin on June 15, 2024, for $25,000. On March 10, 2025, the investor sells the 0.5 Bitcoin for $45,000 through Coinbase. For the 2025 tax year, Coinbase issues Form 1099-DA reporting:

• Date of disposition: March 10, 2025
• Gross proceeds: $45,000
• Quantity: 0.5 BTC
• Acquisition date: Not reported
• Cost basis: Not reported

The investor calculates capital gain using personal records:

The holding period exceeds one year (June 15, 2024, to March 10, 2025), so the gain qualifies as long-term. The investor reports the transaction on Form 8949 and Schedule D, using the gross proceeds from Form 1099-DA as the sales price and personal records for basis.

Example 2: Trading Ethereum for Solana

An investor buys 10 Ethereum on February 1, 2025, for $25,000 total ($2,500 per ETH). On August 15, 2025, the investor exchanges the 10 ETH for 500 Solana when ETH trades at $3,000 and SOL trades at $60. The exchange constitutes a taxable disposition of the ETH.

The fair market value of the SOL received equals:

The capital gain equals:

The holding period of 195 days (February 1 to August 15) falls under one year, so the gain is short-term. The exchange platform issues Form 1099-DA reporting gross proceeds of $30,000. The investor must track the $25,000 basis personally. The SOL acquired in the exchange takes a new basis of $30,000 for future dispositions.

Example 3: Staking Rewards with 1099-MISC

An investor stakes 1,000 ADA (Cardano) through a platform starting January 1, 2025. Over the year, the investor receives 50 ADA in staking rewards. The price of ADA when each reward is received averages $0.40. The total staking income equals:

Since the total from this payer is below $600, the platform does not issue Form 1099-MISC. The investor must still report $20 of ordinary income on Schedule 1, line 8z, or Schedule C if the activity constitutes a trade or business. The 50 ADA acquired as rewards take a cost basis of $20 total, or $0.40 per ADA.

Example 4: Multiple Accounts and Per-Wallet Basis Allocation

An investor holds Bitcoin across three wallets as of December 31, 2024:

• Wallet A: 2 BTC with basis $40,000 ($20,000 per BTC)
• Wallet B: 1 BTC with basis $30,000 ($30,000 per BTC)
• Wallet C: 3 BTC with basis $15,000 ($5,000 per BTC)

The investor previously used the universal method, tracking all 6 BTC as a single pool with total basis $85,000 and average basis $14,167 per BTC. For 2025, the per-wallet accounting rule applies. The investor uses the Rev. Proc. 2024-28 safe harbor to allocate unused basis.

The unused basis calculation:

The average basis matches the universal method average. No adjustment is needed because the sum of wallet bases equals the total basis. If the investor had lost records for some wallets, the safe harbor would allow reasonable allocation to avoid double counting or missing basis.

Reconciling Form 1099-DA with Personal Records

Form 1099-DA simplifies reporting but does not replace personal recordkeeping. Taxpayers must reconcile the information on the form with their own transaction history.

Common Discrepancies

Gross proceeds reported on Form 1099-DA may differ from your calculated proceeds due to fees, wash sales across platforms, or timing differences between trade execution and settlement. The IRS expects taxpayers to report accurate gain or loss using their own records, not blindly copying the information return.

A discrepancy occurs if you transferred cryptocurrency into an exchange from an external wallet before selling. The exchange‘s records show only the transfer in and the subsequent sale. The exchange may lack the acquisition date and cost basis for transferred assets. In this situation, Form 1099-DA reports gross proceeds but leaves basis blank. You must provide the basis using records from the original acquisition.

FIFO vs. Specific Identification

The IRS generally expects taxpayers to use specific identification to select which units they sell. To use specific identification, you must instruct the broker before the sale which units to sell and receive written confirmation. Without specific identification, the default method is first-in, first-out (FIFO).

For 2025, Notice 2025-7 allows alternative identification methods due to broker technology limitations. After 2025, strict specific identification rules apply. The choice of method significantly affects reported gain. A taxpayer who acquired Bitcoin at $10,000, $20,000, and $50,000 can choose to sell the highest-basis units to minimize gain or the lowest-basis units to maximize loss.

Basis Tracking Across Platforms

Investors who use multiple exchanges must track basis consistently across platforms. Selling Bitcoin on Kraken that you originally purchased on Coinbase requires transferring the basis information. Kraken’s Form 1099-DA will report gross proceeds but will not know the original acquisition date or cost basis unless you provided that information to Kraken.

The solution involves maintaining a master transaction log in spreadsheet form or using crypto tax software that aggregates data across platforms. The software calculates gain or loss for each disposition, generates Form 8949, and produces a tax report. The IRS accepts these reports as supporting documentation for the figures entered on your return.

Penalties for Non-Compliance

The IRS has multiple enforcement tools for cryptocurrency tax non-compliance. Understanding the penalty structure encourages accurate reporting.

Failure to File and Failure to Pay

If you fail to file a tax return by the due date, the failure-to-file penalty accrues at 5% of the unpaid tax per month, up to 25%. If you file on time but fail to pay the tax owed, the failure-to-pay penalty accrues at 0.5% per month, also up to 25%.

The combined penalty for willful non-compliance can reach 47.5% of the tax due. For a taxpayer who owes $50,000 in crypto capital gains tax, penalties could add another $23,750.

Accuracy-Related Penalties

Section 6662 imposes a 20% accuracy-related penalty on underpayments attributable to negligence or substantial understatement of income tax. A substantial understatement occurs when the tax shown on the return is less than the correct tax by the greater of $5,000 or 10% of the correct tax.

For cryptocurrency investors, the substantial understatement threshold applies to gains from crypto dispositions. If you fail to report a $60,000 gain that triggers $12,000 in tax, the understatement likely exceeds 10% of your total tax liability, triggering the 20% penalty.

Civil Fraud Penalty

Section 6663 imposes a 75% penalty on any underpayment of tax due to fraud. The IRS bears the burden of proving fraud by clear and convincing evidence, but the penalty applies in egregious cases where the taxpayer intentionally concealed cryptocurrency transactions.

The IRS Criminal Investigation division has secured convictions for cryptocurrency tax fraud. Sentences include prison time in addition to monetary penalties. While most non-compliance results in civil penalties, intentional concealment of substantial crypto gains carries criminal risk.

Practical Steps for 2025-2026 Tax Filing

Crypto investors can take specific actions now to prepare for the new reporting regime.

Step 1 – Organize Transaction Records

Compile complete records of all cryptocurrency acquisitions, including date, amount, cost basis, and source (exchange purchase, transfer, staking reward, airdrop). Include records from all platforms, wallets, and DeFi protocols. For assets acquired before 2025, you need historical basis information even though brokers will not report it.

Step 2 – Choose a Basis Tracking Method

Decide whether to use specific identification or FIFO for 2025 dispositions. If using specific identification, understand the requirements under Notice 2025-7 for the transition period. Document your method in writing and apply it consistently.

Step 3 – Review Rev. Proc. 2024-28 Safe Harbor

If you previously used the universal basis method across multiple wallets, allocate unused basis to each wallet before filing your 2025 return. The safe harbor provides a reasonable method for this allocation. Document the allocation method you choose.

Step 4 – Reconcile 1099-DA Upon Receipt

When you receive Form 1099-DA in February 2026, compare the gross proceeds reported to your personal records. Investigate any discrepancies. If the form reports proceeds for transactions you did not execute, contact the broker to request a corrected form.

Step 5 – File Accurately and On Time

File your return by the April 15 deadline, including all crypto transactions. Use Form 8949 to report each disposition, referencing the 1099-DA proceeds where applicable. Attach a statement if the 1099-DA information differs from your reported figures.
