How to Register a Boat Trailer in Florida: Documents and Fees

To register a boat trailer in Florida, take proof of ownership, a photo ID, and your trailer’s weight information to your county tax collector’s office. What you bring and what you pay hinges on one number: the trailer’s empty (net) weight. Under 2,000 pounds means registration only, no title, no VIN verification, no insurance requirement. At 2,000 pounds or more, the trailer must also be titled and have its VIN verified. New residents have 10 days after establishing Florida residency to complete the process.¹

Why the 2,000-Pound Line Matters

Florida treats trailers weighing 1,999 pounds or less very differently from heavier ones. Light trailers cannot be titled at all, skip the initial registration fee, and don’t need insurance.² Once you hit 2,000 pounds of empty weight, the trailer must be titled and registered, and a VIN verification is part of the paperwork.³

If you’re not sure which side of the line your trailer falls on, a certified weight slip from any public scale will settle it. Homemade trailers need a weight slip either way.

What Documents to Bring

The paperwork depends on where the trailer came from.

A New Trailer

Bring the Manufacturer’s Certificate of Origin (MCO). If there’s a break in the ownership chain between the manufacturer and you, add a bill of sale that fills it in.² If the trailer weighs 2,000 pounds or more, also submit Form HSMV 82040, the title application.⁴

A Used Trailer Already Titled in Florida

The seller signs the transfer section on the back of the existing Florida title and hands it to you. Lighter trailers won’t have a title in the first place, so a bill of sale takes its place. That bill of sale should describe the trailer, list the seller’s Florida plate number, and be signed by both buyer and seller.²

A Trailer From Another State

Bring the out-of-state title as proof of ownership. Some states don’t title lightweight trailers; where that’s the case, the out-of-state registration plus a bill of sale may be accepted. If the trailer weighs 2,000 pounds or more, a VIN verification on Form HSMV 82042 is required. Trailers below that weight don’t need one.³

The verification can be done by the purchaser together with any of the following: a law enforcement officer from any state, a licensed Florida dealer, a Florida notary public, a Division of Motorist Services compliance examiner, or a tax collector employee.³ Buyer and seller can also sign Part A of Form HSMV 82042 together in place of an official verification.

Every registration also requires a valid photo ID. If you haven’t filled out Form HSMV 82040 in advance, you’ll complete it at the counter. The form is available from the FLHSMV website or at any tax collector’s office.

Homemade and Assembled Trailers

If you built the trailer yourself, the process branches again at 2,000 pounds.

Under 2,000 pounds, it’s straightforward. No title is issued, and the state’s computer system generates a Trailer Identification Number (TIN) automatically when you register. Bring a certified weight slip and a bill of sale or affidavit describing how the trailer was built.²

At 2,000 pounds or more, the process moves out of the standard tax collector line and into a regional FLHSMV office. You’ll schedule an inspection with a compliance examiner, who checks the trailer, confirms it’s roadworthy, and assigns an “FLT” number that has to be permanently die-cut or welded onto the trailer in a visible location, usually near the tow hitch.⁵ The initial inspection costs $40, and any follow-ups are $20 each.

For an assembled trailer at 2,000 pounds or more, expect to gather:

A certified weight slip from a public scale showing the empty weight
Form HSMV 82040 (title and registration application)
The FLT Serial Number Assignment form provided at the compliance inspection
An affidavit of assembly describing the build and confirming roadworthiness
A frame affidavit stating the frame is homemade and describing its construction
Bills of sale for all major component parts

All of this is submitted through the regional FLHSMV office rather than a standard tax collector window.⁵

What It Costs

Annual registration is weight-based. For privately used trailers:

500 pounds or less: a flat $18.35 per year
501 pounds and up: $3.50 base plus $1.00 per hundred pounds (cwt) of empty weight, plus $11.60 in service fees

For-hire trailers pay a bit more: $3.50 base plus $1.50 per cwt under 2,000 pounds, or $13.50 base plus $1.50 per cwt at 2,000 pounds and over, each plus $11.60 in service fees.⁶

The metal license plate itself is $28 when first issued.⁷ Trailers under 2,000 pounds are exempt from the initial registration fee that cars and trucks pay.

Title Fees

If your trailer weighs 2,000 pounds or more and needs a title, plan on additional title charges: $77.25 for an original title on a new trailer, $85.25 for a used trailer being titled for the first time in Florida, and $75.25 for a title transfer or duplicate.⁷ Lighter trailers don’t get titled, so none of this applies to them.

Sales Tax

Florida charges 6% state sales tax on the trailer’s purchase price, and many counties add a discretionary sales surtax.⁶ One detail worth flagging: when a boat and trailer are bought together on a single invoice, Florida treats them as one item for calculating the discretionary surtax.⁸ If you want the surtax applied separately, have the seller issue separate invoices or itemize the trailer apart from the boat.

Where to Go and What You Walk Out With

Initial boat trailer registrations are handled in person at your county tax collector’s office or an authorized tag agency. Bring the full document package, ID, and payment. Most offices take cash, check, and card, though some add a convenience fee for card payments.

Once the paperwork clears, you’ll receive a registration certificate, a license plate, and a validation decal. Mount the plate on the rear of the trailer and stick the decal on the plate. For trailers that require a title, the title certificate is mailed to you, or held by your lienholder if you financed the purchase.

Renewing Each Year

Trailer registrations expire annually. For a trailer titled in your personal name, the expiration falls at midnight on your birthday. Business-owned trailers expire at midnight on June 30.⁹ You can renew up to 90 days early.

Renewals can be done through the FLHSMV’s MyDMV Portal online, by mail, in person at a tax collector’s office, or at a self-service kiosk in counties that have them. The renewal fee matches the annual registration rate for your trailer’s weight class.
