Behind the Business: Registering, Insuring, and Licensing Your Trailer Company

Let’s be real—this is the least glamorous part of the business, but arguably one of the most important. Before you even think about towing that shiny new trailer to a wedding in Malibu, you need your business properly set up and protected. At Lux Dumps, we learned through experience that getting your legal and insurance ducks in a row early on saves you from big headaches down the line.

Step 1: Register Your Business

Most restroom trailer rental companies operate as an LLC or S-Corp. Here’s why:

• Limited liability protection for your personal assets
• Potential tax advantages
• Establishes credibility with clients and lenders

Choose a business name (make sure the domain is available), then register with your state. Don’t forget to get your Employer Identification Number (EIN) from the IRS—it’s free and needed for business banking and taxes.

Step 2: Business Bank Account + Accounting Setup

Open a business checking account and keep personal finances separate. Set up accounting software like QuickBooks or Wave to track income, expenses, and mileage. At Lux Dumps, we also recommend having a designated credit card just for fuel and trailer-related expenses to build business credit.

Step 3: Insurance

Don’t skip this. You’ll need:

• General Liability Insurance – Covers property damage and injury (required for events and venues)
• Commercial Auto Insurance – Covers your towing vehicle(s)
• Inland Marine Insurance – Protects the trailer when it’s not hitched to your vehicle

We use a commercial insurance broker who specializes in event vendors—ask around or get referrals in Facebook business groups.

Step 4: Waste Hauling Permits

If you’re not outsourcing your pump-outs and plan to service your own units, you’ll need:

• A DOT number from the Federal Motor Carrier Safety Administration
• A local or county-issued waste transportation permit
• Certification from your local health or environmental services department

Lux Dumps handles our own waste transport in-house, and having a compliant, permitted system has opened doors to higher-paying clients like construction firms and government agencies.

Step 5: Local Licenses + Sales Tax

Check if your city or county requires a local business license. You’ll also need to register to collect sales tax if applicable in your state. Don’t worry—your accountant can help you with filings and timelines. We also recommend setting aside a percentage of every job to a “tax savings” account so you’re never caught off guard.
