Vertex counted 681 combined sales tax rate changes and new rates in 2025, up from 588 the year prior. The rules are changing faster than most businesses realize — and non-compliance discovered during an audit means back taxes, interest, and penalties.
This article covers how sales tax on services actually works, which categories are most commonly taxable, how rules vary across key states, what's typically exempt, and the compliance steps service businesses should take.
Key Takeaways
- Services are not automatically exempt — taxability depends on the specific state and service type
- Five states have no statewide sales tax; most others only tax services explicitly listed in their law
- Post-Wayfair, remote service providers may owe sales tax in states where they've never set foot
- Taxability hinges on three factors: nexus, enumeration, and exemptions
- Legal, medical, and accounting services are exempt in most — but not all — states
Does Sales Tax Apply to Services? Understanding the Basics
Sales tax laws trace back to the Great Depression, when states needed revenue and the economy ran on manufactured goods. The original design was straightforward: tax retail sales of tangible property. Services were largely an afterthought.
That's changed considerably. As the service sector grew, states began adding specific services to their taxable lists — a process still accelerating. Kentucky alone added more than 30 additional service categories effective January 1, 2023.
The U.S. Framework
The current landscape breaks into three groups:
- Five states — Alaska, Delaware, Montana, New Hampshire, and Oregon — impose no statewide general sales tax (Alaska allows local taxes)
- A small group of states — including Hawaii, New Mexico, and South Dakota — tax services broadly by default, unless a specific exemption applies
- Most states take the opposite approach: services are exempt unless explicitly enumerated in state law
In most states, the default is "exempt unless listed" — not the other way around. Whether your specific service appears on a state's enumerated list determines your obligation.
Nexus: The Starting Point for Every Compliance Analysis
Before taxability even matters, a business must determine whether it has nexus — a sufficient connection to a state that creates a tax collection obligation. Nexus comes in two forms:
- Physical presence nexus — a store, office, warehouse, or employees located in the state
- Economic nexus — crossing a state's sales volume threshold, typically based on revenue (commonly $100,000) or transaction count
The 2018 Supreme Court ruling in South Dakota v. Wayfair removed the physical presence requirement, allowing states to impose economic nexus on remote sellers. Today, every sales-tax state has enacted economic nexus rules, though thresholds vary. Many states have also dropped the transaction-count test entirely — as of early 2026, only 15 states and D.C. still maintain one.
The Three-Part Test
For any service transaction, work through these three questions in order:
- Does your business have nexus in the state where the service is delivered?
- Is your specific service enumerated as taxable under that state's law?
- Does any exemption apply — to the transaction, the customer, or the use?
All three must be evaluated for every state where you sell services.
Which Services Are Typically Subject to Sales Tax?
No two states tax the exact same services. But taxable services tend to cluster into recognizable categories — knowing them helps assess exposure before diving into state-specific rules.
Services to Tangible Personal Property
This is the most widely taxed service category — covering repairs, installations, alterations, or improvements to physical goods like car repair, appliance servicing, jewelry repair, and custom tailoring.
States that otherwise exempt most services will often still tax this category. If your business works on physical goods, assume this is a compliance exposure worth checking in every state where you operate.
Personal Services and Services to Real Property
Personal services subject to tax in many states include massage (when not medically necessary), tanning, tattooing, and pet grooming. Rules vary significantly:
- Minnesota taxes massage, pet grooming, and tanning — but excludes grooming for service or utility animals
- Ohio taxes massage, tanning, and tattooing; pet grooming is expressly not taxable there
- Washington taxes tanning and tattooing as retail services
Services to real property — landscaping, janitorial services, construction repairs — are taxable in Texas, Minnesota, Ohio, and Washington, though each state draws its own lines:
- Minnesota: landscape maintenance is taxable; landscape construction is not
- Ohio: lawn care is only taxable when the provider earns $5,000 or more annually from those services
- Texas and Washington: apply tax broadly to most real property service work
Business Services and Amusement/Recreation Services
Business services commonly taxed include:
- Data processing (Texas taxes 80% of the charge)
- Security and alarm monitoring
- Information services
- Parking
- Website hosting
These categories often catch businesses off guard, particularly data processing and website hosting, which many owners assume are exempt. Amusement and recreation services — admissions to sporting events, fitness club memberships, health club fees — are taxed across Texas, New York, Minnesota, and Washington.
One category that's taxable almost nowhere: professional services. Legal, accounting, and medical services are explicitly exempt in most states — though a handful of states do carve out exceptions, so it's worth confirming in any state where you have clients.
How Sales Tax on Services Varies State by State
The range is wide. Some states barely tax services beyond property-related labor. Others have dozens of enumerated taxable categories. Assuming one state's treatment applies anywhere else is one of the most common — and costly — mistakes service businesses make.
California and Illinois: Narrow Bases
California generally does not tax stand-alone services. The key exception: labor that creates, processes, or assembles a tangible product — called fabrication labor — is taxable. Separately stated installation labor is generally not. California is frequently cited as a reference point, but its approach is far more restrictive than most states.
Illinois operates through a Service Occupation Tax, which applies when tangible property is transferred as part of a service transaction. The tax hits the transferred property, not the service itself. Separately contracted installation charges are generally not taxable — but charges bundled into a single price may lose that exclusion.
Texas: One of the Broadest Bases
Texas taxes an extensive list of services, including:
- Data processing and information services
- Amusement and recreation
- Landscaping, pest control, and janitorial services
- Security monitoring
- Catering
Texas also taxes defined "insurance support services" — not insurance premiums, but certain services provided to insurers. The Texas Comptroller's taxable services publication provides the full current list and is the authoritative reference for Texas-based businesses.
New York: Statewide Rules Plus an NYC Layer
Statewide, New York taxes interior decorating and design, protective and detective services, certain parking and information services, storage of tangible property, and admissions to amusement venues. Most services remain exempt.
New York City adds a separate layer: massage, tanning, barbering, manicures, electrolysis, and certain health and weight-control facilities are taxable within city limits but exempt in the rest of the state. Businesses operating in or delivering services to NYC need to account for both layers.
The True Object Test
When a transaction bundles a service with a product, many states apply the true object test to determine taxability. Ohio applies it directly: if the purchaser's primary purpose is a taxable component, the full bundled charge may be taxable. If the taxable item is incidental to an otherwise exempt service, the transaction may escape tax entirely.
Consider a medical device company selling a device alongside a clinical training service. If the state determines the true object is acquiring the device (a taxable product), the entire transaction could be taxable — including the training fee. Separately stating each component and pricing them at fair market value gives you the strongest — and sometimes only — audit defense.
Services That Are Commonly Exempt from Sales Tax
Several service categories receive consistent exemption treatment across most states:
- Medical and healthcare services — generally exempt, though what qualifies varies
- Educational services — exempt in most jurisdictions
- Legal and accounting services — the most consistently exempt professional category
- Services to qualifying nonprofits or government entities — typically exempt with proper documentation
Keep in mind: "most states" is not "all states." Always verify that a specific exemption applies in the state where the transaction occurs before assuming you're covered.
The Resale Exemption
Services purchased for resale are generally exempt. Iowa's guidance illustrates this clearly: an auto repair shop that subcontracts radiator work to another shop does not pay sales tax on that subcontracted service, because tax is ultimately collected from the end customer. The exemption prevents double taxation — but it requires documentation.
Exemption Certificates Matter
Exemptions don't apply automatically. To legally forgo collecting sales tax, sellers typically need a valid exemption certificate from the buyer, on file before the transaction.
Without it, the seller may remain liable for uncollected tax during an audit — even if the transaction genuinely qualified for exemption. Collecting and retaining certificates is a direct audit defense, not optional paperwork.
Sales Tax Compliance Steps for Service-Based Businesses
Step 1: Map Your Nexus
Identify every state where your business has a physical presence or has crossed economic nexus thresholds. Remote service providers and multi-state businesses often have more exposure than they expect — particularly given how many states have quietly dropped the transaction-count test while keeping the revenue threshold.
This step comes first. Taxability analysis is only relevant in states where nexus exists.
Step 2: Verify Taxability, Register, and File
Once nexus is confirmed in a state:
- Research that state's enumerated list for your specific service type
- If taxable, register for a sales tax permit before collecting
- Charge the correct rate, maintain transaction records, and file returns on the required schedule (monthly, quarterly, or annually depending on volume)
Filing without a permit — or collecting tax without remitting it — triggers penalties that compound quickly. The sequence matters.
Step 3: Get Professional Guidance
Multi-state service taxability rules shift constantly — states update thresholds, add new taxable categories, and revise exemptions with little notice. Staying current across multiple jurisdictions is a real operational burden for most businesses.
F.I.C. (Financial Innovations Consulting) works with businesses across Illinois, Minnesota, and nationwide to assess nexus exposure, evaluate service taxability by state, handle multi-jurisdictional filings, and maintain ongoing compliance. Sales tax filing starts at $100 per form per jurisdiction — two states and one city, for example, comes to $300. It's also included in The FIC Package, a bundled plan starting at $500/month that covers bookkeeping, payroll, sales tax, advisory, and year-end returns.
Proactive compliance costs far less than corrections after an audit.
Frequently Asked Questions
Should I add tax to my invoice for services?
It depends on the state where the service is delivered and whether that specific service appears on the state's taxable list. If it does, the seller is responsible for collecting and remitting — failure to collect places the liability on the seller, not the customer.
Do you pay sales tax on services in California?
California generally does not tax stand-alone services. The exception is fabrication labor — work that creates or assembles a tangible product — which is taxable. Verify your specific service type with the California Department of Tax and Fee Administration.
What services require sales tax in Texas?
Texas has one of the broadest service tax bases in the country, covering data processing, amusement, landscaping, janitorial, pest control, security monitoring, catering, and more. Consult the Texas Comptroller's taxable services guide for a complete and current list.
What services are exempt from sales tax in Ohio?
Ohio taxes many services, but common exemptions include hair care, most medical services, and lawn care or landscaping when the provider earns less than $5,000 annually from those services. Confirm specifics with the Ohio Department of Taxation.
Are professional services like accounting or legal work subject to sales tax?
In most states, no — legal, accounting, and medical services are explicitly exempt. A small number of states do tax certain professional services, so location-specific verification is always worth the check.
What are the penalties for not collecting sales tax on taxable services?
Uncollected and unremitted sales tax can result in back taxes, interest, and steep penalties during a state audit. In some states, business owners also face personal liability for unpaid sales tax.
