Illinois titles ALL trailers — there's no weight exemption. Even the smallest utility trailer uses the same VSD 190 + RUT-50 process as cars. The age-based RUT-50 tax often works in favor of used trailer buyers: an 11+ year old trailer is $25 flat tax.

Illinois Requirements: Transfer title within 20 days. 6.25% sales tax.

Common Pitfalls

  • Assuming small trailers don't need titles — Illinois titles ALL trailers regardless of weight.
  • Forgetting plates-to-owner rule on trailers.
  • Skipping RUT-50: even if tax is only $25, the form is required for every trailer transfer.
  • Selling a homemade trailer without SOS-assigned VIN — buyer can't title it.

Pro Tip

IL trailers: every trailer titled, every sale uses VSD 190 + RUT-50, plates belong to the owner. Simple but comprehensive.
