Michigan trailer registration is a one-time, in-person process at a Secretary of State branch. You pay a flat fee of $75 to $300 based on the trailer’s empty weight, and the plate you receive is permanent. There is no annual renewal.1State of Michigan. Recreational Vehicles and Watercraft Trailers weighing 2,500 pounds or more also need a certificate of title.
What to Bring to the Secretary of State
First-time trailer registration cannot be done online. You have to visit a branch office in person with three things:1State of Michigan. Recreational Vehicles and Watercraft
- A valid Michigan driver’s license or state ID.
- The trailer’s weight, either shown on the title or documented with a certified scale receipt.
- Proof of ownership: an assigned title with the seller’s signature, a Manufacturer’s Certificate of Origin, a dealer’s bill of sale, or a private-party bill of sale listing the year, make, VIN, and the names and addresses of both buyer and seller.
Your online Secretary of State account handles things like address changes and replacement titles. Some title transfers can now be started online too, but not the initial registration of a trailer. The name on your registration application has to match the name on your Michigan license or ID.2Michigan Legislature. Michigan Code 257-217 – Application for Registration and Certificate of Title
Registration Fees by Weight
Michigan charges a one-time registration tax based on empty weight, split into three tiers:3Michigan Legislature. Michigan Code 257-801 – Registration Taxes on Vehicle
- Under 2,500 pounds: $75
- 2,500 to 9,999 pounds: $200
- 10,000 pounds and over: $300
Because the plate is permanent, that fee is paid once for the life of the trailer.1State of Michigan. Recreational Vehicles and Watercraft If your trailer weighs 2,500 pounds or more, a title fee is due at the same visit.
When a Title Is Required
The 2,500-pound line decides whether you need a certificate of title:1State of Michigan. Recreational Vehicles and Watercraft
- Under 2,500 pounds: no title required. A bill of sale or prior registration is enough proof of ownership.
- 2,500 pounds and over: a title is required. Bring the assigned title from the seller, or the Manufacturer’s Certificate of Origin from a dealer.
If you’re transferring a titled trailer, also bring any lien termination paperwork. If the weight isn’t printed on the title, bring a scale weight receipt.
Buying or Selling a Trailer
When a trailer changes hands, the buyer has 15 days from the sale to apply for a new title and registration. Miss that window and the Secretary of State can repossess the plate, plus a $15 late transfer fee applies on top of the normal registration costs.4Michigan Legislature. Michigan Legislature Bill Analysis 2023-SFA-0087-F
The seller signs the title over and provides an accurate bill of sale. The buyer takes that signed title, a Michigan license or ID, and payment to a branch office. For a trailer under 2,500 pounds that was never titled, a signed bill of sale with the VIN, year, make, and both parties’ details is enough.1State of Michigan. Recreational Vehicles and Watercraft
One point that trips people up: the seller’s permanent plate stays with the seller. The buyer registers the trailer in their own name and gets a new plate.
Temporary Plates Come From Dealers, Not the State
Michigan does issue temporary plates, but only through licensed dealers at the point of sale. They’re valid for up to 30 days while the permanent registration is being processed, and only one temporary plate can be issued per purchase. If the dealer charges you for it, the charge cannot exceed what the Secretary of State charged the dealer.5Michigan Legislature. Michigan Code 257-226a – Temporary Registration Plates
Temporary plates are not available for private-party sales, and they are not a way to legally use a trailer you have owned for a while but haven’t registered.
Homemade and Assembled Trailers
If you built the trailer yourself, or substantially rebuilt one, Michigan treats it as an “assembled vehicle” and requires a different process before it can be used on public roads.6State of Michigan. Instruction for Titling an Assembled Vehicle BFS-72
You need ownership documentation or a bill of sale for every major component: frame, axles, wheels, and body or box if the trailer has one. Each bill of sale should list the seller’s name, address, phone number, a description of the parts, and any serial numbers. You’ll fill out a TR-34 certification form explaining how the trailer was built.
Before your branch visit, two things have to happen. Have the trailer weighed at a certified scale (lumber yards and scrap yards often have them), and have a Michigan law enforcement officer complete a Vehicle Number/On-Road Equipment Inspection Form. Towing the empty, unregistered trailer to the scale is allowed for this purpose.6State of Michigan. Instruction for Titling an Assembled Vehicle BFS-72
At the branch, staff computes a new VIN for the trailer. There’s a $10 VIN sticker fee, and a 6% use tax applies to the materials that went into the build unless you have sales receipts showing the tax was already paid. Plan on 8 to 10 weeks between application and receiving the title and VIN sticker. No temporary permit is issued during that wait, so the trailer stays off public roads until the paperwork clears.
Exemptions From Registration
Farm and Agricultural Trailers
Michigan defines an “implement of husbandry” as a vehicle or trailer used exclusively for agricultural, horticultural, or livestock operations, including farm wagons and trailers adapted to carry farm equipment.7Michigan Legislature. Michigan Code 257-21 – Implement of Husbandry Trailers meeting that definition are fully exempt from registration and title requirements.8Michigan Legislature. Michigan Legislature Bill Analysis 2011-SFA-1121-S
“Exclusively” does the work in that definition. Using the trailer for farm work during the week and personal hauling on the weekend generally takes it out of the exemption. The status attaches to the use, not to whether the owner runs a farm.
Qualifying Nonprofits
Reduced rates apply to vehicles owned by certain nonprofits: nonprofit veterans centers, nonprofit recycling centers, federally recognized conservation organizations, nonprofit food pantries and food banks, the Civil Air Patrol, and emergency support vehicles owned by federally recognized charities. Eligible vehicles pay $10 per plate. Vehicles owned by bona fide religious or charitable corporations pay 65 cents per 100 pounds of empty weight. Documentation of nonprofit status is required.3Michigan Legislature. Michigan Code 257-801 – Registration Taxes on Vehicle
Penalties for Skipping Registration
Operating an unregistered trailer is a civil infraction, not a criminal offense. A “no proof of registration” violation carries a base fine of $18, which grows to roughly $93 to $111 once court costs and state assessments are added. A registration or plate violation has a $35 base fine and totals around $110 to $128.9Michigan Courts. Civil Infraction Fine Schedule The statutory maximum fine is $100, before those costs and assessments are stacked on.
Fines double in work zones, school zones, school bus zones, and at emergency scenes. Commercial motor vehicles face a higher maximum of $250. Given that a permanent plate costs as little as $75, the arithmetic favors registering.
Federal Requirements for Heavier or Interstate Trailers
State registration handles Michigan’s side of the ledger. A trailer used in interstate commerce with a gross vehicle weight rating of 10,001 pounds or more triggers a separate federal step: the owner or operator has to obtain a USDOT number from the Federal Motor Carrier Safety Administration. Hauling hazardous materials in intrastate commerce triggers the same requirement regardless of weight.10FMCSA. Do I Need a USDOT Number?
Carriers crossing state lines also register under the Unified Carrier Registration program. The 2026 UCR fee starts at $46 for operators with two or fewer commercial motor vehicles and scales up by fleet size.11UCR. Unified Carrier Registration
Federal safety rules add equipment obligations too. Trailers with a gross weight over 3,000 pounds generally have to have independent brakes and a breakaway braking system that engages automatically if the trailer separates from the tow vehicle.12eCFR. 49 CFR Part 393 Subpart C – Brakes These federal rules sit on top of Michigan’s, and both state police and federal inspectors check for compliance during roadside inspections.
