Licenses & Permits in Washington

General Business License

Washington State requires most businesses to obtain a Unified Business Identifier (UBI) through the Business Licensing Service (BLS) of the Department of Revenue. Washington has no state income tax, but does have a Business and Occupation (B&O) tax applied to gross receipts, which is unique among US states. Additionally, businesses must register for the B&O tax and any applicable retail sales tax. Many cities require a separate city business license endorsed onto the state license through a streamlined endorsement system.

Frequently Asked Questions

Starting a welding business typically requires $15,000–$40,000, covering welding equipment ($3,000–$8,000), a vehicle and trailer ($3,000–$10,000), safety equipment ($500–$1,000), insurance, and working capital. A mobile welding setup serving job sites has lower overhead than a fixed shop.

Shop welding rates range from $65–$125/hour. Mobile and structural welding commands $85–$175/hour. Certified pipe welders earn $35–$50/hour as employees or $100–$200/hour as contractors. Custom fabrication is often quoted as a fixed project price with 40–60% material markup.

Certifications aren't legally required for general repair and fabrication work, but AWS D1.1 structural steel certification is required for many commercial, government, and infrastructure projects. Pipe welding certifications (6G position) can triple your earning potential in oil/gas and industrial sectors.

Mobile welding has lower overhead (no shop rent) but higher vehicle and fuel costs. Shops enable more complex fabrication but require $2,000–$8,000/month in rent. Many welders start mobile and transition to a shop as volume grows. Specializing in one niche (agricultural repair, pipeline, custom automotive) typically yields the highest returns.
