The IRS was perceived as being behind the curve for a number of years following the widespread use of Bitcoin. The agency’s current tools were unable to keep up with the speed at which cryptocurrency transactions flowed between wallets and exchanges, and a generation of owners of digital assets operated under the careless belief that the intricacy of the blockchain would shield them from serious scrutiny. The speed at which this assumption is being tested in court is accelerating.
Cryptocurrency-related criminal investigations increased by 113% between 2018 and 2023; crypto-related audits increased by 52% between 2024 and 2025; and the conviction rate for financial crimes involving digital assets remained at 90%. The IRS has declared that the age of tolerance is over with an almost institutional directness.

The change is being driven by a combination of legislative and technical mechanisms. Brokers must report sales and trades of digital assets in the same format as traditional securities transactions using Form 1099-DA, which will be required starting in the 2025 tax year. The 1099-DA eliminates the plausible deniability for anyone who has been discreetly keeping their cryptocurrency winnings a secret in the hopes that no one would notice.
The IRS receives the data directly. In addition, the requirement for brokers to report cost basis on a wallet-by-wallet basis eliminates the opportunity for investors to selectively choose high-basis assets when determining taxable gains. In a single legislative cycle, the accounting flexibility that cryptocurrency holders had become accustomed to has been drastically reduced.
Those who haven’t been paying close attention are surprised by the technology used in enforcement. AI-powered blockchain forensics, created by firms like Chainalysis, are being used by the IRS to track transactions between wallets, exchanges, and mixing services that were made expressly to conceal ownership. One major obstacle for anyone attempting to conceal transactions on the blockchain is that it is public by design. Combining services makes things more complicated, but it doesn’t make them invisible.
In ways that manual inquiry could never have accomplished at this volume, AI technologies that process transaction graphs at scale are able to spot patterns and connect wallets to identities. With more than 60 countries having ratified the OECD’s Crypto-Asset Reporting Framework, which promotes cross-border data exchange with a focus on evasion through foreign exchanges, offshore accounts are also becoming more visible.
It’s important to comprehend the high-risk categories that the IRS will prioritize in 2026. The yields produced by lending or locking cryptocurrency in protocols, as well as staking incentives, are taxable as regular income at the time of receipt rather than when they are sold. It is inappropriate for many holders to perceive them as unrealized until conversion.
Capital profits are produced by NFT sales. When assets are transferred between blockchains, like Ethereum and Solana, cross-chain bridge transfers may result in taxable events if they are mistakenly categorized as non-taxable transactions. These are technical mistakes that appear harmless in practice, but an AI-assisted audit will find them first.
It’s difficult to ignore the fact that individual investors who entered the cryptocurrency market between 2020 and 2022, during the height of retail enthusiasm, and kept records either poorly or not at all, are the ones most vulnerable to this enforcement surge rather than sophisticated institutional traders with compliance departments.
Noncompliance can result in fines of up to $250,000 and, in extreme circumstances, jail time. The IRS isn’t making a distinction between someone who didn’t comprehend the rules and someone who purposefully avoided them. That distinction is also not made by the tools.
