IRS Crypto Cost Basis Reporting Starts With 2026 Trades: What Every Investor Needs to Know

Quick Answer: Irs Crypto Cost Basis

Starting with cryptocurrency transactions completed on or after January 1, 2026, centralized exchanges and other digital asset brokers must report both gross proceeds and cost basis to the IRS on Form 1099 DA, closing a gap that previously let many crypto gains go unreported. For 2025 transactions, brokers were only required to report gross proceeds, often leaving cost basis blank or defaulted to zero, which could overstate an investor's taxable gain if not corrected. Crypto is taxed as property, with short term gains taxed as ordinary income up to 37 percent and long term gains taxed at 0, 15, or 20 percent. Experts estimate that only about a third to just over half of taxpayers with crypto holdings have historically reported their transactions, a gap the new reporting rules aim to close.

Key Takeaways: Irs Crypto Cost Basis

• Starting with transactions effected on or after January 1, 2026, digital asset brokers must report both cost basis and gross proceeds to the IRS on Form 1099 DA, according to IRS final regulations.

• For 2025 transactions, reported on Form 1099 DA in early 2026, brokers were only required to report gross proceeds, not cost basis, which could leave investors' original purchase price undocumented.

• The IRS eliminated the universal wallet cost basis method starting in 2025, replacing it with a wallet by wallet accounting method that requires tracking cost basis separately for each account or wallet.

• Cryptocurrency is taxed as property. Short term gains on assets held one year or less are taxed as ordinary income at rates up to 37 percent, while long term gains are taxed at 0, 15, or 20 percent depending on income.

• Experts estimate that only roughly 32 to 56 percent of taxpayers with crypto holdings have historically reported their transactions to the IRS, a gap that new broker reporting aims to close.

• The IRS defines digital asset brokers broadly to include centralized exchanges, payment processors, hosted wallet providers, and stablecoin issuers that redeem their own tokens, though noncustodial and decentralized platforms remain exempt for now.

• Every taxpayer must answer the digital asset question on Form 1040 each year, whether or not they received a Form 1099 DA, and whether or not they engaged in any crypto activity.

• Tax professionals are increasingly using blockchain analytics tools to identify unreported crypto activity, and the IRS has separately warned taxpayers about phishing letters impersonating a fake digital asset compliance portal.

What Actually Changed in the Reporting Rules

For most of the last decade, crypto tax compliance ran largely on the honor system. The IRS declared in 2014 that cryptocurrency counts as property for tax purposes, meaning nearly every sale, swap, or purchase made with crypto is technically a taxable event, but exchanges had no standardized way to report that activity to the government the way stock brokers have reported trades for years.

That changed with the rollout of Form 1099 DA, the IRS's new information return for digital asset transactions. For the 2025 tax year, filed in early 2026, brokers were required to report only gross proceeds from crypto sales, the total dollar amount an investor received. Cost basis, meaning what the investor originally paid for the asset, was left off many of those forms. Without cost basis on file, the IRS can end up seeing a large sale number with no purchase price attached, which can make it look like the entire amount was pure profit unless the taxpayer's own return shows otherwise.

Beginning with transactions completed on or after January 1, 2026, that gap closes. Brokers are now required to report both gross proceeds and cost basis on Form 1099 DA, bringing crypto reporting in line with how stock and mutual fund brokers have reported trades since cost basis rules were phased in for securities starting in 2011.

The Wallet by Wallet Change That Trips Up Investors

A second, less publicized change has been reshaping how cost basis gets calculated in the background. Starting with 2025 activity, the IRS no longer allows the universal wallet method, which let investors pool similar assets held across multiple accounts and calculate cost basis as one combined average. In its place, taxpayers must now use wallet by wallet accounting, tracking cost basis separately for each individual account or wallet.

For an investor who only ever used one exchange, this change barely registers. For anyone who has moved crypto between multiple exchanges, self custody wallets, or DeFi platforms over the years, it can meaningfully complicate recordkeeping, since a coin's cost basis now depends on exactly which wallet it sits in, not just when it was originally purchased.

Who Counts as a Broker and Who Does Not

The IRS defines a digital asset broker broadly. Centralized trading platforms, payment processors, hosted wallet providers, and stablecoin issuers that regularly redeem their own tokens all fall under the reporting requirement. Brokers are not required to issue Form 1099 DA to foreign individuals, corporations, financial institutions, or tax exempt organizations, and transactions between two digital asset brokers are also exempt from the reporting rule.

Noncustodial platforms, meaning services that never take control of a user's assets, are not currently treated as brokers under the rule, which leaves a meaningful slice of decentralized finance activity outside the new reporting net for now. That does not make DeFi income tax free. Staking rewards, lending yields, and other crypto income remain taxable whether or not a broker reports them, and taxpayers are still legally required to track and report that activity themselves.

CNBC reporting on the IRS's expanding capabilities noted that some experts estimate only about a third to just over half of taxpayers with crypto holdings have historically reported their transactions correctly, a gap regulators are actively working to close through both new broker reporting and more sophisticated blockchain analytics tools used to trace wallet activity back to individual filers.

What Irs Crypto Cost Basis Means for Your Money

If you have crypto spread across more than one exchange or wallet, now is the time to reconcile your own cost basis records rather than assuming your 1099 DA forms will capture everything correctly, particularly for any assets you held before 2026 that a broker may still report with incomplete basis information.

Key Takeaways Recap: Irs Crypto Cost Basis

Starting with transactions completed on or after January 1, 2026, digital asset brokers must report both cost basis and gross proceeds to the IRS on Form 1099 DA, closing a gap that previously left many crypto gains effectively self reported. A related change eliminated the universal wallet cost basis method in favor of wallet by wallet accounting, complicating recordkeeping for investors who use multiple exchanges or wallets. Crypto remains taxed as property, with short term gains taxed as ordinary income and long term gains taxed at preferential rates. With the IRS expanding both broker reporting and blockchain analytics, investors who have not historically reported crypto activity correctly face a shrinking window before enforcement catches up.
