Washington has no state personal income tax, but applies a Business & Occupation (B&O) tax on gross receipts that applies broadly to service businesses -- confirm current treatment with the Washington Department of Revenue.
Filing fees change periodically — confirm the current fee directly with the Washington Secretary of State before filing. This is general informational content, not legal or tax advice.
Licensing varies by state — don't guess
Most states license home inspectors with some combination of training hours, a supervised inspection count, and an exam -- but a smaller number of states have no state-level licensing requirement at all. Confirm the current rule with your state's licensing board before planning your timeline.
ASHI & InterNACHI
The two major national home inspector associations, each offering training and voluntary certification. Neither replaces your state's licensing requirement where one exists.
