The Growing Complexity of US Sales Tax on Services

US sales tax traditionally applied to products, not services, but many states are expanding their tax base to include services—especially digital offerings like SaaS and ebooks. Services fall into four categories: business, personal, professional, and maintenance/repair. Five states have no sales tax, four tax services by default, and the rest tax only specifically listed services. Multi-state businesses must conduct nexus studies, register for sales tax permits, apply the correct rates, file returns, and monitor law changes to stay compliant. As service taxation grows more complex, proactive compliance and automation tools are key to avoiding penalties and keeping up with evolving state rules

Categories of Services

Services generally fall into four groups:

• Business services (advertising, IT, consulting, payroll)
• Personal services (dry cleaning, hair care, tanning)
• Professional services (accountants, lawyers, doctors)
• Maintenance & repair services (car repairs, landscaping, building improvements)

State-by-State Rules

• No sales tax at all: NH, OR, MT, AK, DE
• Tax services by default: HI, SD, NM, WV (exceptions must be specified)
• Others (41 states + DC): Tax only services explicitly listed in their statutes
  Examples: Hawaii taxes nearly all services; Texas taxes dry cleaning but exempts veterinary services.

Compliance Challenges

Multi-state businesses must understand each state’s rules for every product or service sold. A nexus study is essential when entering a new state or adding a new service line. For example, a CPA firm expanding from Arizona (CPA services untaxed) to New Mexico (CPA services taxable) must register, collect, and remit New Mexico’s Gross Receipts Tax or risk paying it out of pocket.

Compliance Steps

• Register for sales tax permits where you have nexus
• Research and apply correct tax rates (including local rates)
• File and remit returns on time
• Monitor law changes — services untaxed today may become taxable tomorrow

Sales tax on services is one of the most rapidly evolving areas of state tax policy, driven by budget needs and the digital economy. Businesses must stay proactive with nexus reviews, product/service taxability research, and rate updates to avoid costly compliance gaps. Automation tools like TaxJar can simplify multi-state compliance and reduce risk.
