Illinois Digital Asset Tax: DEXs Seek a Broker Carve-Out
A DeFi advocacy group wants Illinois to say that decentralized exchanges are not digital asset brokers under the state's new Digital Asset Tax Act. If the Illinois Department of Revenue agrees, tax collection and computation duties would sit elsewhere. If it doesn't, firms with DeFi exposure face a new layer of state-level data and tax work. For anyone building a DeFi accounting process, this is a proposal to watch closely.
What happened: DEXs ask Illinois for a carve-out
The request
According to Bloomberg Tax, the DeFi Education Fund, a research and advocacy group that promotes decentralized finance, has asked the Illinois Department of Revenue to change its draft proposed rules implementing the Digital Asset Tax Act. The group wants the department to exempt peer-to-peer cryptocurrency trading platforms from tax collection and computation duties. The Act is described as the first tax on digital assets of its kind in the nation.
The core ask is a clarification. The fund says the department should state that decentralized exchanges, or DEXs, cannot be characterized as digital asset brokers. The request was made in a letter sent to the revenue department on a Friday. The report also indicates that the venture capital firm Andreessen Horowitz and the software company Uniswap Labs were involved in the push, though the excerpt available to us is cut off, so we won't characterize what they asked for beyond that.
Where the process stands
This is a proposal stage item. The department has draft proposed rules, and an industry group is commenting on them. Nothing here is final, and the outcome could change before any rule takes effect. Treat the broker question as open.
Why the broker label matters for DeFi accounting
Collection and computation duties follow the definition
In tax regimes that rely on intermediaries, the definition of "broker" decides who has to calculate the tax, who has to collect it, and who holds the underlying records. The fund's request is aimed at exactly that point. If a DEX were treated as a broker, it would be pushed toward computing and collecting tax on peer-to-peer trades. If it isn't, the burden stays with someone else, most likely the transacting parties themselves or other intermediaries in the chain.
The practical difficulty is easy to see. A decentralized exchange built on smart contracts often has no account relationship with the trader, no obligation to hold customer identity records, and no ability to see the user's cost basis from activity elsewhere. Asking such a protocol to compute a tax liability raises design and legal questions that the advocacy group is putting in front of the regulator.
What we can't say yet
The excerpt we have does not describe the tax rate, the transaction scope, the effective date, or the penalty framework in the draft rules, and we won't guess at them. Anyone advising on exposure should read the Act and the draft proposed rules directly from the Illinois Department of Revenue rather than rely on summaries.
Implications for firms, CFOs and auditors (B2B)
Scoping and data lineage
If you service clients that trade on DEXs, the open broker question changes what data you can expect to receive. Under an intermediary model, you might get structured reporting from a collecting party. Under a carve-out, the client is the only reliable source of record, and the evidence sits on-chain: wallet addresses, transaction hashes, token flows, and protocol interactions. That pushes weight onto your own ledger and reconciliation tooling.
Firms evaluating crypto accounting software should test whether it can ingest wallet-level and protocol-level activity, not only centralized exchange exports. DeFi activity includes swaps, liquidity provision, and token approvals, and each has to be mapped to a ledger treatment. A tool that only reads exchange CSVs will leave a gap exactly where this proposal is focused. The same goes for crypto bookkeeping software and digital asset accounting software more broadly: the question to ask is how it documents source, timing, and valuation for on-chain events.
Controls and audit evidence
For auditors and finance teams, an unresolved definition is a control design problem. Reasonable steps that don't depend on the final outcome include:
- Inventory which entities and wallets transact with decentralized exchanges and which jurisdictions their users or staff sit in.
- Confirm you can reconstruct disposal proceeds and cost basis from on-chain data without relying on a third-party statement.
- Document how the entity determines Illinois nexus, if it has any, and who owns that determination.
- Keep a change log for rule developments so the position taken at each reporting date is traceable.
Multi-state complexity
A state-level digital asset tax adds to an already fragmented US picture. A client with Illinois-connected activity may need state-specific treatment on top of federal reporting. Even if the Illinois rule changes, the precedent matters: other states watch first movers, and your process should be able to absorb state-by-state variation without a rebuild each time.
Implications for individual filers (B2C)
If you trade on a DEX
If you swap tokens on a decentralized exchange and live or are otherwise connected to Illinois, you shouldn't assume the platform will do any tax work for you. The fund's request is precisely that DEXs not be made to compute or collect. If the department agrees, the responsibility to track and report stays with you. If it doesn't, you could see new reporting touchpoints, but that outcome isn't settled.
What to do now
Keep clean records regardless of how this lands. Save wallet addresses, export transaction histories, and note the date, token, quantity, and USD value of each swap. Records are far easier to assemble as you go than to rebuild later from block explorers. Don't change filing positions based on a proposal. Wait for the department's final rules, and consider speaking with a tax professional if you have significant DeFi activity.
What to watch next
Signals from the department
Watch for revised draft rules, published comments, and any definition of "digital asset broker" that addresses non-custodial or peer-to-peer platforms. The wording of that definition will determine whether the DeFi Education Fund's request is met in full, in part, or not at all.
Why this matters beyond Illinois
Whichever way the department rules, it will be an early test of how a US state treats decentralized protocols in a tax collection framework. For firms, that makes it a useful planning input. It sits alongside broader work on crypto compliance reporting, and it connects to how firms think about risk in DeFi-heavy books, a theme we covered in enterprise risk management for crypto-active financial services firms.

FAQ
What is the Illinois Digital Asset Tax Act?
It is described by Bloomberg Tax as the first tax on digital assets of its kind in the US. The Illinois Department of Revenue has draft proposed rules implementing it, and those drafts are now drawing comments.
What is the DeFi Education Fund asking for?
It wants the department to exempt peer-to-peer crypto trading platforms from tax collection and computation duties, and to clarify that DEXs can't be characterized as digital asset brokers.
Is the exemption approved?
No. This is a request made on draft proposed rules. The department has not, based on the information we have, granted it.
Does this affect my DeFi accounting now?
It doesn't change current obligations by itself, but it is a reason to make sure your records can reconstruct on-chain activity independently of any platform.
Who else is involved?
Bloomberg Tax indicates that Andreessen Horowitz and Uniswap Labs were also part of the push. The excerpt is truncated, so check the full report for details.
