Crypto Tax Reporting: Navigate New IRS Rules for 1099-DA and W-9 Requirements

Crypto Tax Reporting Feels Uncertain Right Now in 2026

There has been a lot of debate around crypto tax reporting in recent years. The current reporting process in place is outdated and does not reflect the fast-moving nature of cryptocurrency. With regulatory expectations constantly evolving, brokers and filers are getting left behind. A study by CoinTracker and Coinbase revealed that 61% of respondents were unaware of 2025 tax rules, including Form 1099-DA.

Most brokers are aware of Form 1099-DA to report gross proceeds but starting 2026 (2027 filing season), even cost basis “covered securities” (certain digital assets) for transactions occurring on or after January 1, 2026, has to be reported. Earlier, cost basis reporting was voluntary but now it's mandatory. However, only 35% have ever adjusted cost basis. This lack of certainty can create reconciliation headaches later down the line.

At the same time, companies are working with large volumes of transaction data and customer profiles that may not always be complete or standardized. Some brokers may face delays or readiness challenges when preparing Form 1099-DA for the 2026 tax year. For these high-volume exchanges, the delay came from the lack of preparedness and data quality concerns. These exchanges had to build entirely new reporting systems from scratch.

There is a tax readiness gap in cryptocurrency, and it is causing compliance issues. Teams are expected to prepare for year-end reporting while rules are still being clarified. Any data gap that might have been manageable before is now more visible.

What 1099-DA Changes Mean for Crypto Reporting

Form 1099-DA is a new form in the IRS 1099 Form series. It was first introduced for 2025 tax year transactions, which were filed in early 2026. This form helps increase IRS visibility into crypto activity. Before this form was introduced, crypto tax reporting was largely a self-reporting activity. It represents a shift in how digital asset transactions are reported.

Since it's a fairly new form, there is still confusion around its reporting scope. For the 2025 tax year transactions, only gross proceeds from digital asset sales were reported. For the 2026 tax year, the IRS has increased the reporting scope by including cost basis reporting for covered security assets. This means that you have to report what the taxpayer originally paid for the crypto (cost basis) and the sale amount (gross proceeds).

As 1099-DA reporting requirements evolve and change, the focus is on building a reporting process that is adaptable and scalable. Since the form’s reporting scope is expanding, it places more responsibility on the filer to organize crypto transactions in a standardized format so gross proceeds, cost basis, customer details, and other required information can be reported correctly on Form 1099-DA.

Why W-9 Collection Becomes a Year-Round Requirement

A major part of IRS digital asset reporting compliance is ensuring customer data is accurate and complete. And in order to get access to accurate data, you need Form W-9.

In crypto environments, W-9 collection is typically done at the time of onboarding. Collecting the taxpayer details before fully onboarding them onto the platform before any trading or issuing of payment begins, not only saves time but makes sure the information is accurate before filing season starts.

A Form W-9 contains the legal name of the taxpayer, their TIN, current address, any exemption status, and signature. This information is required when filing Form 1099-DA and if the data is not always complete at the time of onboarding because the taxpayer delayed providing information, submitted incomplete details, or entered data that does not match IRS records, it could create issues that might even lead to penalties or notices.

With so much resting on accurate W-9 information, waiting until the year-end to resolve any gaps that occur creates more risk and delays filing. The W-9 collection and validation process should be an ongoing process with teams continuously collecting, validating, and monitoring this information throughout the year.

Year-End Reporting Risks for Crypto Brokers

For crypto brokers, year-end reporting comes at a risk of incorrect filing if the proper compliance steps are not taken into account

Incomplete Customer Tax Profiles

Before any reporting even begins, you should have collected and validated customer tax profiles. Having incomplete customer information such as missing names, TINs, addresses, or W-9 certifications can delay filing and cause potential backup withholding issues. Without complete and accurate customer tax profiles, the IRS may have difficulty matching the form and reported transactions to the correct individual taxpayer.

Transaction Data Is Not Tax-Ready

Crypto transaction data cannot be used in tax forms as it is. Raw trading data is not always ready for reporting, and it may include different types of activity, such as sales, exchanges, transfers, fees, stablecoin transactions, etc. These transactions have to be categorized, validated, and formatted correctly before they can be mapped to 1099-DA reporting requirements. Classification of each of these transactions should also be done, whether it's a sale, transfer, or a qualifying stablecoin sale, these activities can become a manual and time-consuming step.

Cost Basis and Gross Proceeds Data May Be Difficult to Standardize

Cost basis and gross proceeds are two sides of the same coin. Both have to be reported on Form 1099-DA. As previously mentioned, cost basis is what was originally paid for the crypto and gross proceeds is the sale amount. Both gross proceeds & cost basis are mandatory 1099-DA reporting requirements for 2026TY (but basis reporting for noncovered securities is optional). The data for these requirements usually comes from multiple sources, depending on how the transactions were recorded. Standardizing this information requires consistent rules and validation where teams have to spend a lot of their time reconciling the data.

Not Every Crypto Transaction Is Reportable

There are some crypto transactions that are not yet properly defined under reporting requirements for Form 1099-DA. Transactions, such as NFTs, stablecoins, liquidity pool activity, staking, etc., are more complicated. The IRS has provided optional reporting methods or temporary exceptions for some of these transactions, but brokers still need to identify them correctly and understand whether it should be reported or excluded. Because 1099-DA reporting is new, mistakes in classifying these transactions cause delayed filings, and even possible penalties.

Last-Minute Rule Changes Create Rework

One of the biggest challenges in crypto reporting is uncertainty. Since crypto reporting is still pretty new, IRS is still playing catch up to ensure proper compliance and reporting. The reporting requirements are not set in stone and may change at the last minute. If 1099-DA reporting workflow is rigid, your team may be forced to adjust as new guidance, exceptions, or form instructions are released. This causes more rework and delays in filing.

Year-End Readiness Crypto Reporting Checklist

To prepare for evolving 1099-DA reporting requirements, your team should focus on building a strong foundation before the start of filing season. Use this checklist to measure your year-end readiness:

• Identify all customers and accounts that have reportable digital asset transactions and categorize them as reportable.
• Collect Form W-9 from the U.S. customers, or the appropriate Form W-8 from foreign customers when they are being onboarded to the platform.
• Validate TINs early in the process and request a corrected Form W-9 to receive the correct information.
• Determine what belongs on Form 1099-DA and whether any activity belongs elsewhere or is excluded.
• Have workflows prepared for any corrections, especially when customer data or transaction classifications change after filing.
• Maintain audit-ready documentation of how you classified transactions, calculated proceeds or basis, and handled exceptions.
