Illinois Dog License Requirements

Updated October 13, 2026 · 2 min read · 2 sources

Short answer

Illinois leaves dog registration to counties under the Animal Control Act (510 ILCS 5/3). County boards may require registration and microchipping and must charge intact animals at least $10 more. Veterinarians file a rabies certificate with the county when they vaccinate, and the county sets the rabies tag fee. Many cities add their own license.

Illinois does not run a single statewide licensing program, but state law lets counties or cities require dog licenses, and many do.

What Illinois law says

  • 510 ILCS 5/3 lets county boards require dog registration and microchipping by ordinance.
  • Registration fees must be at least $10 higher for intact animals.
  • Vets who vaccinate send the rabies certificate to the county administrator, and the county sets the tag fee (5/8).
  • Redeeming an impounded dog requires proof of rabies vaccination and registration (5/10).
  • Municipalities may impose a dog tax (65 ILCS 5/11-20-9).

How to find out if your Illinois city or county requires a license

  1. Check your city or county animal services or animal control website; it usually lists license rules and fees.
  2. If you live outside city limits, check the county rules, which can differ from the city's.
  3. Have your rabies certificate ready; local licenses almost always require proof of rabies vaccination.
  4. Ask whether a microchip, spay/neuter proof or a multi-year license lowers the fee.

Licenses, rabies shots and microchips

Dog licenses and rabies vaccination usually go together: the license office or the veterinarian checks the rabies certificate before a tag is issued. See Illinois rabies vaccination laws for the required age and booster rules. A license tag helps animal control return a lost dog quickly, and a microchip is a permanent backup if the collar comes off.

What happens if your dog is not licensed?

Where a local license is required, an unlicensed dog found at large can be picked up by animal control, and getting it back usually means paying impound fees and buying the license. Penalties are listed above where the state statute sets them; local ordinances often add their own fines. Leash and at-large rules are covered in Illinois leash laws.
