Whether you owe sales tax on services by state depends almost entirely on where the transaction happens and what kind of service is involved. Four states tax services by default. Most states tax only the services they’ve specifically named in their tax code. Five states charge no general sales tax at all. The same haircut, repair job, or software subscription can be fully taxable on one side of a state line and completely exempt on the other.
The Three State Approaches
There is no federal sales tax. Every state writes its own rules, and each state falls into one of three camps.
Hawaii, New Mexico, South Dakota, and West Virginia tax services by default. A service is presumed taxable in those states unless the legislature has carved out an exemption. If you sell services there, assume you’re collecting tax and work backward from that assumption.
The other 41 states with a sales tax, plus the District of Columbia, do the opposite. Services are presumed exempt unless the state has affirmatively listed them as taxable. A web design firm in New Mexico collects sales tax on every project. The same firm in Virginia likely owes nothing, because Virginia hasn’t enumerated web design as a taxable service.
Alaska, Delaware, Montana, New Hampshire, and Oregon have no general statewide sales tax. Alaska does allow local jurisdictions to impose their own, so a business operating there still needs to check municipal rules.
The practical takeaway: if you sell across state lines, check each state individually. One state’s treatment tells you nothing about the next.
Which Services Get Taxed Most Often
Repair and Maintenance Labor
Work on physical items is the most commonly taxed service category. Automotive repair, appliance servicing, and clothing alterations appear on taxable service lists in a wide range of states. The labor is usually taxed at the same rate as any replacement parts, so the full invoice carries tax.
Work on Buildings and Land
Services performed on real property also trigger sales tax in many states. Landscaping, janitorial services, pest control, and certain construction or remodeling work show up on taxable lists across a significant number of jurisdictions. The provider collects the tax and remits it on a monthly, quarterly, or annual schedule based on volume.
SaaS, Streaming, and Digital Services
Software as a Service, cloud storage, and streaming subscriptions are the fastest-changing area of sales tax law. Roughly 20 to 25 states now treat SaaS as taxable, including Arizona, Connecticut, New York, Pennsylvania, Texas, and Washington. California, Florida, Georgia, and Virginia currently do not. Because legislatures keep adjusting these rules to catch up with how people actually spend money, a service that was exempt last year can become taxable this year. Verify the current rule before you rely on last year’s answer.
Professional Services
Legal counsel, accounting, architecture, and engineering remain exempt in the vast majority of states. This is one of the few areas of broad consensus. New Mexico and South Dakota both tax professional services, and a handful of others, including Kentucky and Ohio, have started taxing certain professional categories. Even in an exempt state, the final deliverable can become taxable if it qualifies as tangible personal property or a taxable digital product.
When a Job Mixes Goods and Services
Plenty of real transactions blend a product with labor. Tax authorities sort these using the True Object Test, which asks what the buyer actually wanted. If the customer’s real goal was the service and any physical item was incidental, the transaction leans exempt. If the customer really wanted the product and the labor was just the means of delivering it, the whole charge leans taxable.
States use different labels for the same idea. Texas calls it the “essence of the transaction” test. Michigan looks at whether goods are “incidental to the service.” Rhode Island calls it the “real object.” A printing company that designs and prints marketing materials is selling tangible goods with incidental design work. A consultant who hands over a written report is selling a service with an incidental physical product.
Some states add a de minimis threshold on top of the True Object Test. If the tangible goods represent a small enough share of the price, they’re ignored and the whole charge is treated as a service. The Streamlined Sales and Use Tax Agreement uses 10% as its standard threshold.
Bundled Invoices: Itemize or Pay Tax on the Whole Thing
A single invoice that combines taxable goods with a nontaxable service at one lump price creates a bundled transaction. A security company charging one flat fee for camera hardware and installation labor is the classic example. If the invoice doesn’t break the charges apart, many states will apply sales tax to the entire amount.
The fix is simple: itemize. List the goods and services as separate line items and tax only the taxable portion. In many states, itemizing is the only way to protect the service portion from tax.
Some states apply a de minimis exception here too. Under the Streamlined Sales and Use Tax Agreement, if the taxable products are 10% or less of the total price, the invoice isn’t treated as a bundled transaction. Individual states set their own thresholds. Texas uses 5%. Illinois has historically applied roughly 35%. Knowing your state’s number can matter when the goods portion of a mostly-service job is small.
Does an Out-of-State Seller Have to Collect?
Before taxability even comes into play, a state has to be able to require you to collect. That question turns on nexus, meaning a sufficient connection to the state. An office, employees, or a storefront in the state is physical nexus and creates a collection obligation on its own.
The bigger shift came in 2018, when the Supreme Court decided South Dakota v. Wayfair, Inc. The court ruled that a state can require remote businesses to collect sales tax based purely on economic activity, without any physical presence, overruling the earlier physical-presence requirement.1Supreme Court of the United States. South Dakota v. Wayfair, Inc. (06/21/2018)
The most common economic nexus threshold is $100,000 in sales into a state during a calendar year. California uses $500,000. New York requires $500,000 combined with at least 100 transactions. Alabama and Mississippi set their threshold at $250,000. When Wayfair was decided, South Dakota’s law also included a 200-transaction alternative, and many states initially copied that. The trend since has been to drop the transaction count. As of 2026, more than a dozen states have eliminated it entirely, including South Dakota itself, leaving only the dollar amount.
Crossing back out of a state is harder than crossing in. Many states impose trailing nexus, requiring you to keep collecting and remitting for a period after your sales fall below the threshold. Common trailing nexus periods run through the end of the current calendar year plus the entire following year. Some states require continued collection until you formally cancel your sales tax registration. Check the rule before you stop.
Rates themselves range from 2.9% to 7.25% at the state level, with combined state and local rates reaching as high as 10.11% in some areas.2Tax Foundation. State and Local Sales Tax Rates, 2026 Most states source a service to the customer’s location; about a dozen source it to the seller’s location instead.
Use Tax: The Buyer’s Version
When you buy a taxable service from an out-of-state provider who doesn’t collect your state’s sales tax, the tax doesn’t disappear. Every state with a sales tax also imposes a use tax at the same rate, and the buyer is legally responsible for reporting and paying it. This applies to both businesses and individual consumers.
Compliance is low, mostly because most people don’t know the obligation exists. Many states have added a use tax line to their income tax return to make self-reporting easier. Businesses with substantial out-of-state purchases face much higher audit risk than individuals, and the amounts involved are usually larger.
What Getting It Wrong Costs
Failing to collect, collecting but not remitting, or filing late all trigger penalties in every state. Late-payment penalties typically run 5% to 25% of the unpaid tax, climbing the longer the delinquency continues. Interest on top of penalties commonly runs 3% to 18% annually, often tied to the federal prime rate.
Deliberately keeping tax you’ve already collected from customers is treated much more seriously. Some states classify it as a criminal offense, and personal liability can attach to business owners and responsible officers even when the business itself is the registered collector. If you’re unsure about a particular service, automate collection and file on schedule anyway. Overpaying and requesting a refund is almost always cheaper than underpaying and getting audited.
