Watch dealing in Illinois: the Resale Dealers Act

Illinois runs the cleanest statewide secondhand regime this site has covered so far — and it does it without a state licence or a state agency. The Resale Dealers Act, 815 ILCS 398, puts real duties on you and then hands enforcement entirely to your county sheriff or your municipal police chief.

No licence, but a floor that cities must build on

There is nothing to apply for at state level. What there is instead is § 55, and it is worth reading precisely:

Nothing in this Act shall be construed to impair the power of a county or municipality, including home rule units, to enforce the provisions of this Act or to license, regulate, suppress, or prohibit resale dealers, provided that any such actions are no less restrictive than required by this Act.

Most states preserve local power in both directions. Illinois preserves it in one: a city may go further than the Act, and may not go less far. The section says so as an express limitation on home rule under art. VII, § 6(i) of the Illinois Constitution.

So the Act is your floor everywhere in Illinois, and your city can only raise it. Chicago raises it substantially.

The open question: is a steel watch "jewelry"?

The Act reaches a business that buys, sells, consigns or trades "jewelry, stamps, electronic equipment ... or any precious metals that have been previously owned by a consumer."

Watches are never named. "Jewelry" is never defined.

Precious metals, though, are defined, and broadly: any item containing gold, silver, platinum, palladium or rhodium. So:

• A gold or platinum watch is inside the Act on the precious-metals limb, and the definition of jewelry never has to be resolved.
• A steel watch is inside only if "jewelry" reaches it, and nothing in the Act says whether it does.

If any part of your buying is precious metal, the point becomes academic — the duties attach to you as a business, not item by item.

One more provision that catches modern dealers. Section 5 makes it prima facie proof that a business is a resale dealer if it (i) advertises in any fashion, including through websites, that it buys or sells used items, and (ii) devotes a significant segment of its premises to that trade. Limb (i) describes almost every dealer's own homepage.

What you actually have to do

A record book someone else approves. Section 15 requires a standard record book that has been approved by the appropriate law enforcement official. You do not pick the format, and there is no state office to ask — it is your sheriff or your police chief. Entries go in in English, printed, typed or written in ink, at the time of each sale, and must include the serial number. No completed entry may be erased, mutilated or changed.

Identification, one form or two. A driver's licence or Secretary of State ID card bearing a photograph is enough on its own. Anything else means two forms, one of which must show the seller's address.

A daily report before noon. Every day, a legible and exact copy from the record book goes to the same official, by whatever means they authorise.

Three years of records, for every resale dealer regulated by the Act.

The purchase you must refuse

Section 25 forbids buying from anyone under 18, from anyone who cannot produce the required identification, and — the one that matters here —

the article to be purchased had an original manufacturer's serial number at the time it was new, but no longer legibly exhibits such number.

An over-polished caseback, a replacement case, a movement swapped into an unnumbered shell: on the face of the statute those are purchases you are not permitted to make. Section 30 separately forbids you removing, altering or obliterating any make, model, serial number or identifying mark.

Ten days, at the address where you bought it

Section 40 sets 10 days before you may expose for sale, sell, trade, barter, melt, destroy or otherwise dispose of any individually identifiable article, and 3 days for a non-identifiable one. Any watch carrying a serial number plainly qualifies.

Then § 40(b) adds a second constraint that most holding rules leave out: the goods must remain at the premises where the purchase happened until the period expires.

Read that against how watch deals actually happen. Buy in a hotel suite at a show, or across a seller's kitchen table, and on the statute's wording the piece stays there for ten days. Quite how a dealer who trades without a shopfront is meant to satisfy that is a real question, and it is on the attorney list.

Watch shows are drafted out of the exemption

Section 10 exempts "consumer shows or exhibitions of collectibles" — and then immediately excepts "a show or convention that offers to buy second hand jewelry from attendees."

A watch show with a buying table is the thing the exception describes. The exemption you might have expected to rely on is removed by the same sentence that grants it.

Penalties escalate to a felony

Section 50 sets a $750 fine for a first or second offence, as a petty offence. From there it depends which duty you breached:

• Records, daily report, prohibited purchases, inspection — Class B misdemeanor on a third offence, Class A on a fourth or later.
• Identifying marks, holding period, hold orders — Class A misdemeanor on a third offence, and a Class 4 felony on a fourth or subsequent one.

Selling a watch early is in the second group.

Tax

The state Retailers' Occupation Tax is 6.25% on general merchandise, and 1% on qualifying drugs and medical appliances. Locally imposed taxes are added on top of that, and Illinois publishes local rates only through the MyTax Illinois Tax Rate Finder rather than as a static schedule.

That means this page cannot tell you the combined rate for your address, and we are not going to guess at one. Look it up before you quote a price — the local component in Cook County is not small.

Two things changed on 1 January 2026, and both matter to anyone shipping watches.

First, the remote-seller threshold. Illinois used to catch a remote retailer or marketplace facilitator on either $100,000 of cumulative gross receipts into Illinois or 200 separate transactions. Public Act 104-0006 removed the transaction limb. The only test now is $100,000 or more in cumulative gross receipts over the 12-month lookback — which, in a trade where single sales run to five figures, is a threshold reached on volume of money rather than volume of deals.

Second, and less widely noticed: where a taxpayer fails to supply enough information to determine the proper location of a destination-based sale, IDOR assesses the gross receipts of those sales at 15%, assigned to "undetermined tax locations". Ordinary unprocessable-return penalties do not apply — the 15% is the consequence. And the department states that the rate may be used during an audit for any periods under audit, including reporting periods before January 2026.

If your records do not show where each watch was actually delivered, that is the rate the shortfall gets taxed at.

Where to go next

Chicago licenses secondhand dealers, names watches explicitly where the state Act does not, sets a watch-specific record schedule that includes a colour photograph of every watch, and forbids buying before 6 a.m. or after 9 p.m.

For the nationwide layer, start with cash reporting.
