1. New Hampshire — No Sales Tax

   New Hampshire has no state sales tax and no local sales taxes, so businesses need no sales tax permit or resale registration for sales tax purposes. Businesses may instead owe the Business Enterprise Tax and the Business Profits Tax, both administered by the NH Department of Revenue Administration; BET paid can be credited against BPT. Restaurants, caterers and lodging operators separately collect the Meals and Rooms (Rentals) Tax and must hold a DRA license for it. Filing and payment are handled through DRA's Granite Tax Connect portal.

2. Nashua Wash Water Discharge Rules — No Permit or Fee

   Pressure washing businesses must not wash detergents, chemicals or contaminants into storm drains. In Nashua this is an illicit-discharge prohibition administered by the City's Wastewater Department under its stormwater and pretreatment program, backed by state NHDES stormwater rules — Hillsborough County has no environmental compliance role. There is no per-business stormwater discharge permit product for pressure washers; operators are expected to contain and recover wash water and dispose of it to the sanitary sewer or a licensed facility.
