Why this matters

Remote service providers — freelancers, consultants, SaaS vendors, online coaches, and other non‑storefront sellers — often assume sales tax only applies where they have a physical presence. That assumption is risky after South Dakota v. Wayfair, Inc. (2018), which allowed states to require out‑of‑state sellers to collect sales tax based on economic activity rather than physical presence (South Dakota v. Wayfair, 138 S. Ct. 2080 (2018)). Since then, most states have adopted economic nexus standards or marketplace facilitator rules that can create collection responsibilities for remote service providers.

In my work advising small businesses and solo practitioners, I regularly see missed registrations and late filings because owners didn’t track sales by state or understand how states treat services. Below I walk through how nexus works, how states tax services, practical compliance steps, and common traps to avoid.

How nexus is established for remote services

States typically use one or more of these concepts to establish sales tax nexus:

  • Physical presence: owning or leasing property, having employees or agents in‑state, or attending trade shows. This remains a traditional trigger.
  • Economic nexus: reaching a sales-dollar or transaction threshold in the state (for example, many states use $100,000 or $500,000 in sales or a 200‑transaction rule). After Wayfair, economic nexus is the dominant driver for remote sellers.
  • Marketplace facilitator nexus: marketplaces (for example, booking platforms or digital storefronts) may be required by law to collect and remit tax on seller transactions.

States differ in thresholds and tests. Examples commonly cited are California ($500,000), Texas ($500,000), New York ($500,000 and 100 transactions), and New Jersey ($100,000 or 200 transactions) — but always confirm against the state revenue department for the latest figures, as thresholds and rules sometimes change. See your state’s Department of Revenue for current limits.

Do states tax services the same way as goods?

No. Whether a service is taxable depends on the state and the nature of the service. Categories that are frequently taxable in some states include:

  • Digital goods and subscription services (in many states)
  • Telecommunications and streaming
  • Installation or repair services tied to tangible personal property
  • Certain professional services in a handful of states

Consult state law and guidance for definitions and exemptions. For example, software delivered as a service (SaaS) is taxable in some states and exempt or treated as a non‑taxable service in others.

Sourcing rules: where is the sale considered to occur?

States follow either destination‑based or origin‑based sourcing rules to decide which jurisdiction gets the tax:

  • Destination sourcing (most common): tax rate and rules of the customer’s location apply.
  • Origin sourcing: tax of the seller’s location applies (less common; used by some local jurisdictions for certain transactions).

For remote services, destination sourcing is common: you generally charge tax based on the customer’s address. That makes accurate customer addresses and reliable tax automation critical.

Step‑by‑step compliance checklist for remote service providers

  1. Inventory your services and determine whether each is taxable in the states where you sell. Start with the states that produce the most revenue.
  2. Track sales by state and the number of transactions on a rolling 12‑month basis so you can compare against economic‑nexus thresholds.
  3. Register for sales tax permits in any state where you’ve established nexus. Do not rely on marketplace platforms unless a marketplace facilitator law explicitly transfers collection responsibility.
  4. Determine sourcing rules for each taxable service and set up tax calculation tied to the customer’s location.
  5. Decide whether to collect tax at the point of sale or inform customers of use tax obligations (if the state allows). For B2C sales you generally collect; for B2B sales customers may provide resale or exemption certificates.
  6. File timely returns and remit collected tax to each state (frequency depends on volume and state rules).
  7. Keep robust records: invoices, exemption certificates, customer addresses, and marketplace receipts for at least the period your state requires (often 3–7 years).

Use automated solutions (e.g., tax engines integrated with your checkout, accounting software, or payment processor) to reduce manual errors. FinHelp has a practical guide on How to Implement Sales Tax Automation for Small Businesses.

Marketplace facilitators and who actually collects

Most states now impose marketplace facilitator laws that require the marketplace to collect and remit sales tax on behalf of third‑party sellers. This relieves many remote service sellers of the collection burden, but not always the registration or reporting obligations. Review the specific law and your marketplace agreement. See FinHelp’s analysis: Marketplace Facilitator Rules: Who Collects and Remits Sales Tax?.

Common pain points and mistakes

  • Assuming no physical presence means no tax liability — Wayfair changed this.
  • Failing to monitor rolling 12‑month sales and transactions that trigger economic nexus.
  • Misclassifying services (e.g., calling a taxable digital subscription “consulting”).
  • Relying solely on a marketplace without confirming the state law or the marketplace’s compliance.
  • Poor recordkeeping of exemption certificates or customer locations — this undermines your defense in an audit.

If you discover past noncompliance, many states offer voluntary disclosure agreements (VDAs) that limit lookback periods and penalties. Contact the state revenue department or a tax professional promptly.

Practical examples

  • Freelance graphic designer: If you sell $120,000 worth of design services to customers in State X where the threshold is $100,000, you may need to register and collect tax in State X even if you live elsewhere.
  • SaaS vendor: Some states tax SaaS; others do not. Determine categorization and apply destination sourcing rules to customer accounts (billing address or IP geolocation as allowed).
  • Marketplace seller: If you sell lessons via a platform that collects fees and remits tax, read the platform’s seller agreement and check state law to confirm the marketplace is the collecting party.

If you’re audited or get a notice

  • Respond quickly and gather supporting documentation (sales by state, filing history, exemption certificates).
  • Consider a voluntary disclosure before an audit if you find unreported nexus exposure.
  • If assessed tax and penalties, negotiate payment plans or penalty abatement when possible.

Professional tips from practice

In my advising practice I recommend the following:

  • Build a routine (quarterly) nexus review that lists states with sales above a conservative threshold (for example, $50k) so you catch upcoming exposure early.
  • Use a tax engine that integrates with your invoicing and payment system to apply correct rates and collect necessary customer data for sourcing.
  • Maintain a short memo for each state documenting the legal basis you used to classify a service as taxable or exempt — this helps during audits.

Where to get authoritative guidance

  • Read the South Dakota v. Wayfair decision for legal background (SCOTUS opinion).
  • Consult your state Department of Revenue website for current economic nexus thresholds and filing procedures.
  • For practical small‑business resources, review guidance from the Consumer Financial Protection Bureau and the IRS for general tax compliance practices, recognizing state sales tax is administered at the state level.
