Free Kansas Trailer Bill of Sale
Kansas measures your trailer WITH its load: if trailer plus cargo stays at or under 2,000 pounds, registration isn't required and the title is OPTIONAL — the owner can request one but doesn't have to — while above 2,000 pounds the full title-and-registration process applies at the county treasurer within Kansas's generous 60-day window. Farm trailers get extra slack, staying exempt until the load itself passes 6,000 pounds. Where paperwork applies, the tax is Kansas's usual 6.5% plus local rates (near 10% in the Johnson County metro), documented on the state's TR-312 bill of sale.

Sales Tax Details
Same 6.5% + local taxes apply to trailers.
Kansas Trailer Sale — Step-by-Step Checklist
- Weigh trailer PLUS load: at or under 2,000 pounds combined = no registration required, title optional; above = full title and registration.
- Verify the VIN or serial plate on the tongue against the title where one exists.
- Complete Form TR-312 (Kansas's bill of sale) with VIN/serial, type, weight, sale price, date, and both signatures.
- Seller signs the title over (2,000-plus trailers, or where a voluntary title exists).
- Buyer files at the county treasurer within 60 days.
- Buyer pays 6.5% state tax plus local county/city rates.
- Buying a sub-2,000-lb trailer without a title? Consider requesting the OPTIONAL Kansas title — it upgrades your ownership evidence cheaply.
Common Pitfalls
- Judging the empty trailer only — Kansas counts trailer plus cargo against the 2,000-pound line, so light trailers with heavy loads need plates.
- Walking away from a title-less light trailer — under 2,000 pounds the title is optional in Kansas; the registration-free trailer with only a bill of sale can be entirely legitimate.
- Overloading the farm exemption — farm trailers lose it when the load passes 6,000 pounds.
- Quoting the 6.5% alone — Johnson County metro buyers pay closer to 10% once local rates stack.
Pro Tip
Kansas trailers: the 2,000-pound trailer-plus-load line separates paperwork-free from full process, farm rigs get slack to 6,000 — and the optional title is the smartest cheap upgrade in the state.
