How to Start a Plumbing Business in New York
Register your business entity
Register your LLC or corporation with the New York Secretary of State. This is your first step even though New York does not require a state-level plumbing contractor.
Obtain your EIN
Apply for a federal Employer Identification Number (EIN) from the IRS. This is free and can be done online at irs.gov.
Check your city/county requirements
Since New York does not have a state-level license, check with your local city or county for registration requirements. Many cities in New York require local contractor registration or permits.
Get general liability insurance
Obtain general liability insurance ($500K-$1M minimum recommended). While New York may not require it by law, most clients and project owners will require proof of insurance before hiring you.
Get workers' compensation insurance
If you have or plan to hire employees, workers' compensation insurance is required in New York. Even as a sole proprietor, consider it for personal protection.
Register for state and local taxes
Register for New York sales tax and any local business taxes. Set up your business bank account and accounting system.
Build your credentials
Without a state license requirement, your reputation is everything. Consider voluntary certifications, join local trade associations, collect reviews, and maintain a professional online presence.
