Illinois faces lawsuit over new crypto tax

TLDR

Illinois has enacted a 0.2 percent digital asset transaction tax that is now being challenged in court by major crypto industry groups.

1. The new law imposes a 0.2 percent tax on the value of digital asset trades, transfers, and custody via brokers serving Illinois customers.
2. Industry groups argue the tax is discriminatory, legally flawed, and could force crypto firms to limit or cut off services to Illinois residents.
3. The outcome of the lawsuits will shape whether similar digital asset transaction taxes spread to other US states or are deterred.

Deep Dive

1. What Illinois Passed And Who Is Suing

Illinois adopted the nations first explicit 0.2 percent digital asset tax, scheduled to take effect on 1 January 2027, targeting trades, transfers, and custody activity through crypto intermediaries. The levy applies to businesses that trade or store crypto for Illinois customers and meet a revenue threshold, effectively taxing the infrastructure that supports digital asset usage rather than just investor profits.

On 21 August 2026, the Blockchain Association and Crypto Council for Innovation filed suit in Sangamon County Circuit Court against key state officials, seeking to block enforcement of the new Digital Asset Tax Act. A separate challenge from the Chamber of Digital Commerce was already filed, creating a coordinated legal front against the measure.

2. Why The Tax Is Being Called Discriminatory

Plaintiffs argue that the tax unlawfully singles out digital assets, since similar activities involving stocks, cash, gold, or securities do not face a comparable transaction tax. Because the levy is based on transaction value, businesses would owe tax even when customers lose money or when assets simply move between accounts without an economic gain.

The complaints claim violations of the US Constitution, the Illinois Constitution, and the Internet Tax Freedom Act, pointing to issues like taxing electronic commerce differently, burdening interstate activity, and a legislative process where a budget bill expanded to more than a thousand pages with limited public scrutiny.

3. Impact On Crypto Users And What To Watch

Practically, crypto exchanges, custodians, and other intermediaries serving Illinois may need complex systems to track taxable events, and some could restrict or drop Illinois customers to avoid liability if the law stands. Multiple taxable triggers per trade, plus civil or criminal penalties for errors, raise compliance risk and cost.

Conclusion

Illinoiss digital asset tax turns routine crypto activity into a taxable base, and the resulting lawsuits will test how far states can go in targeting crypto infrastructure. For now, the key signal to watch is whether courts grant injunctions before the 2027 start date, which will tell you if this model is likely to spread or stall.
