How to Register Your Field Service Business in the US

Starting a field service business is one of the fastest paths to self-employment. You can be earning within a week of getting your equipment. But skipping the legal setup is a mistake that costs money and headaches later. Here is how to do it right.

First, choose a business structure. For most solo operators, a sole proprietorship or a single-member LLC is the right call. A sole proprietorship is the default when you start working under your own name. An LLC (Limited Liability Company) costs a small filing fee, usually $50 to $200 depending on your state, and separates your personal assets from your business. If someone sues your business, they cannot come after your car or house. That protection is worth the fee.

Second, pick a business name and check availability. Search your state's Secretary of State website to confirm the name is not already taken. If you are operating under a name other than your legal name (for example "Sparkle Pro Wash" instead of "John Smith"), you may need to file a DBA ("doing business as") with your county.

Third, get an EIN. An Employer Identification Number is like a social security number for your business. It is free from the IRS and takes five minutes at irs.gov. You need it to open a business bank account and to separate your business taxes from your personal taxes.

Fourth, open a business checking account. Keep business money separate from personal money from day one. This makes tax time infinitely simpler and gives your business credibility when customers see a professional name on invoices and receipts.

Fifth, get any licenses your state or city requires. Most states require a general business license. Some states require a contractor license for pressure washing businesses. Check your state's business licensing portal and your city or county government site.

Sixth, get liability insurance. A $1 million general liability policy costs $50 to $100 per month for most field service businesses. If you crack a customer's window or damage their car, you want insurance paying for it, not you.

That is it. Six steps, most of which you can complete in a single afternoon. Once you have your LLC, EIN, bank account, and insurance, you are a legitimate business.
