Illinois has published draft implementation rules for its Digital Asset Tax Act, giving payment processors, exchanges, custodians and wallet providers their clearest view yet of which customer transactions could carry the state’s new 0.2% charge from Jan. 1, 2027.
The Illinois Department of Revenue posted the draft on Sept. 28 and is accepting comments through Oct. 30. The department stressed that the text has not yet been filed with the Illinois Secretary of State or submitted to the Joint Committee on Administrative Rules. The operational details are therefore proposals, not final regulations, even though the underlying tax has already been enacted.
Stablecoins are inside the proposed tax base
The draft treats stablecoins as digital assets because they function as a medium of exchange, unit of account or store of value while remaining distinct from fiat currency. It also lists conventional cryptocurrencies, memecoins and blockchain-based central bank digital currencies as covered examples. Non-fungible tokens would be excluded under the proposal.
The tax would apply at 0.2% of the digital asset’s value when a covered exchange, transfer or storage activity is completed. A taxable event would need four elements: an Illinois customer, receipt of digital asset business activity, valuable consideration and a digital asset broker. The activity must also be reflected by an entry on a blockchain.
That structure matters for payments companies because the draft’s broker category extends beyond trading venues. It includes centralized exchanges, custodians, broker-dealers and digital payment processors that manage or directly custody assets for customers. DeFi exchanges that retain protocol or operating fees could also qualify.
Merchant acceptance and processor activity are separated
Illinois retailers accepting digital assets for goods or services would not themselves be treated as digital asset brokers and should not add this tax to a customer’s retail purchase. The processor or exchange handling the underlying transfer or conversion may nevertheless create a separate taxable digital asset service.
One example in the draft describes a customer scanning a merchant processor’s QR code and paying an exchange fee to transfer digital assets from a managed wallet. The state treats that transfer as taxable because a broker facilitated it for consideration. In a separate example, a merchant’s processor converts an incoming digital asset payment to local fiat; the draft treats the merchant as the processor’s customer for that conversion.
For payment providers, this distinction points to a transaction-modeling requirement. The retail sale, customer wallet transfer and merchant-side conversion may be related operationally, but they are not necessarily the same event for tax purposes. Systems would need to identify the relevant Illinois customer, the broker performing each service and the asset value when the covered blockchain movement occurs.
Fees determine the treatment of DeFi and wallet transfers
DeFi transactions would generally remain outside the tax unless they are performed for what the proposal calls valuable consideration. Network or gas fees paid to miners and validators, along with swap fees directed solely to liquidity providers, would not count. Protocol fees collected to operate or maintain a DeFi platform would count, potentially bringing the transaction and platform within scope.
The same fee-based test shapes wallet activity. A transfer from a centralized exchange to a self-custody wallet would be taxable when the exchange completes the transfer and charges a fee. A direct peer-to-peer transfer between personal wallets, without a broker or other consideration, would not be. Internal balance changes that do not move assets on a blockchain would also fall outside the proposed transaction definition.
Bridging is expressly listed as an exchange of assets from one blockchain network to another. It would therefore be potentially taxable when the broader customer, broker and consideration tests are met, rather than automatically taxable in every case.
Location data and collection systems will be central
For electronic transactions, the draft creates a rebuttable presumption that a customer is in Illinois when account or device records show an Illinois home, business or mailing address, an Illinois IP address, or an Illinois place of primary use. Federal customer-location records, including information collected during know-your-customer checks, could support the sourcing decision.
Brokers maintaining a place of business in Illinois would have to collect and remit the tax, show it separately from the service purchase price and remain liable even if they failed to collect it. The draft also provides for registration with the Revenue Department. Its definition of a business presence includes an out-of-state broker with at least $100,000 in gross receipts from digital asset business activity sold to Illinois customers.
The immediate task for industry participants is not simply adding a 0.2% line item. Firms will need to map custody, conversion and transfer flows; distinguish broker-retained fees from network and liquidity-provider fees; establish reliable customer-location evidence; and prevent a merchant sale from being confused with the digital asset services supporting it. Because the rules remain pre-filing drafts, those implementation choices should be tested against the final text after the comment and rulemaking process is complete.
