Illinois has postponed the effective date of the Digital Asset Tax Act, known as DATA, by six months, moving the first state-level tax of its kind in the United States from January 1, 2027 to a possible July 1, 2027 start.

The delay arrives while multiple lawsuits challenge the law in Sangamon County Circuit Court. The Digital Chamber and the Blockchain Association are among the plaintiffs, arguing the measure fails on several constitutional grounds — with federal preemption, the principle that federal law outranks state law in certain areas, at the center of the dispute.

What the tax does

DATA imposes a 0.2% tax on digital assets used in exchanges, transfers, or storage services. The levy falls on brokers serving Illinois customers, and it applies regardless of whether a trade is profitable. A $10,000 transfer would carry a $20 tax whether the asset doubled in value or lost half of it. Illinois projected approximately $60 million in annual revenue from the measure.

Governor JB Pritzker signed the law on June 16, 2026 as part of the state's FY2027 budget, meaning it arrived bundled with broader fiscal legislation rather than as a standalone bill.

The compliance stakes for brokers are severe. Brokers that fail to collect the tax could face Class 3 felony charges, carrying up to five years in prison and fines of $25,000.

Draft rules already on the table

The postponement also follows negotiations between state officials and industry representatives. In late September 2026, the Illinois Department of Revenue released draft implementation rules covering how the levy would apply to stablecoins, non-fungible tokens, and certain decentralized finance activities.

The original timeline was ambitious — arguably untenable. The law was signed in mid-June 2026, draft rules landed in late September, and brokers were left only a few months to digest guidance and rebuild their systems before the January 1, 2027 deadline.

Operational consequences

For Illinois crypto users, the delay buys breathing room rather than relief. The tax has not been repealed. The new date is described as a possible July 1, 2027, not a guaranteed one, and pending litigation could reshape the outcome in either direction.

Brokers carry the sharpest exposure. They are responsible for collecting the tax, and they face felony penalties for noncompliance. The six-month extension gives compliance teams additional runway to build collection infrastructure, but firms serving Illinois customers still lack final rules to engineer against.

The delay may also signal caution among other states weighing similar frameworks. If the federal preemption argument succeeds in Sangamon County, the ruling could become precedent that discourages copycat legislation elsewhere.

The developments to watch are a ruling from the Sangamon County Circuit Court, the final version of the Department of Revenue's draft rules, and whether the July 1, 2027 date holds through the remaining legislative and legal window.
