Illinois at a Glance
Primary agencies, processing channels, common amounts, deadlines, and high-use transaction controls.
Illinois Secretary of State
Titles and registers motor vehicles, motorcycles, trailers, recreational vehicles, manufactured homes, ATVs, OHVs, and related plate classes through Vehicle Services, ERT/PERT, remitters, and facilities.
Illinois Department of Revenue
Administers dealer sales tax, out-of-state use tax, private-party vehicle tax, watercraft use tax, local tax, credits, penalties, and interest through ST-556 and the RUT form family.
Illinois DNR
Handles watercraft and snowmobile registration/title transactions and administers public-access OHV requirements. These fees and checks are separate from SOS vehicle transactions.
High-use statewide reference
Ordinary title
$165 for most motor vehicles, motorcycles, and trailers.
Passenger registration
$151 annually for standard passenger plates.
State dealer/use-tax rate
6.25% before exact seller-location or purchaser-address local adjustments.
Duplicate/corrected title
$50 plus any registration-card correction or expedited service.
Plate transfer
$25 when a qualifying current Illinois plate is transferred.
Mandatory ELT threshold
Beginning July 1, 2026, lienholders processing five or more Illinois vehicle liens annually must participate in ELT.
Deadlines and workflow
New resident / Illinois entry
Title, registration, insurance, emissions, and applicable use-tax filings generally must be addressed within 30 days. IDOR calculates applicable late tax, penalty, and interest.
Illinois dealer tax filing
ST-556 is generally due no later than 20 days after delivery, even when the title transaction remains in processing.
Manual and title-only processing
Manual applications and title-only transactions can require 10–12 weeks in the ILTS workflow. Processing time is an estimate, not a guaranteed SOS service level.
Separate payment streams
Secretary of State title/plate fees, IDOR tax, IDNR recreational-unit fees, and UCC filing fees must remain separated and routed to the correct agency.
