How does state tax nexus affect subscription-based businesses?

Subscription-based businesses must monitor nexus because membership fees, recurring digital services, and shipped goods can each trigger state tax obligations in different ways. After the U.S. Supreme Court decision in South Dakota v. Wayfair, Inc. (2018), many states shifted to “economic nexus” rules that tax out-of-state sellers once sales or transaction thresholds are met (see state Department of Revenue guidance).

Background and why it matters

Nexus is not one-size-fits-all. Historically, states relied on physical presence to establish nexus; after Wayfair, states added economic tests based on in-state sales or transaction counts. That means a subscription company with no offices or employees in a state can still owe sales tax if its sales into the state exceed the state’s trigger (many states use tests like $100,000 in sales or 200 transactions, but thresholds vary—always confirm with the state’s revenue department).

In my practice working with subscription SaaS and box-subscription clients, missing a nexus trigger often led to months of uncollected sales tax and awkward customer communications while correcting past returns. Early monitoring prevents that disruption.

How nexus is commonly established for subscriptions

  • Physical presence: offices, employees, contractors, inventory stored at a fulfillment center or third-party warehouse.
  • Economic presence: reaching a state’s sales- or transaction-based thresholds (post-Wayfair economic nexus rules).
  • Marketplace and marketplace facilitator rules: some platforms collect and remit sales tax on sellers’ behalf—know whether a facilitator covers your subscription model (check platform agreements).
  • Taxability rules: states differ on whether subscriptions are taxable; digital subscriptions, bundled offerings, and SaaS are treated differently across states.

For statutes and state-specific rules, consult the state Department of Revenue site. For federal guidance about multistate tax issues and reminders on withholding or reporting that may affect employees, see the IRS (irs.gov).

Practical examples

  • A subscription box company ships physical goods from one state but sells nationwide. When sales into State A exceed that state’s economic threshold, the company must register, collect State A sales tax, and file returns.
  • A SaaS provider with no physical footprint can still hit economic nexus in a state where recurring subscription revenue passes the threshold and must begin tax collection there.

Compliance checklist for subscription businesses

  1. Map where subscribers live and track gross sales and transaction counts by state.
  2. Review fulfillment and storage locations (including third-party logistics/warehouses).
  3. Confirm marketplace facilitator rules if you sell through platforms.
  4. Determine the taxability of your specific subscription (digital content, SaaS, and physical products are taxed differently by state).
  5. Register proactively in states where you exceed thresholds and begin collecting sales tax on new sales per state rules.
  6. Keep clear records to support exemptions, refunds, and historical compliance if you discover uncollected tax.

Common mistakes to avoid

  • Assuming uniform rules: states vary on thresholds, product taxability, and filing requirements.
  • Neglecting third-party warehouses: inventory at a fulfillment center often creates physical nexus.
  • Overlooking bundled pricing: combining taxable goods and untaxed services can change tax treatment.

Cost-control and strategy tips

  • Automate nexus tracking and tax calculations with a certified sales-tax engine that updates state rules.
  • Consider economic impact of registration: some states allow simplified filing or small-seller exemptions—review options before registering everywhere.
  • Use accurate product/service descriptions and exemption certificates when appropriate to reduce over-collection and administrative burden.

Frequently asked questions

Q: How do I know when to start collecting sales tax?
A: Start collecting when you meet a state’s nexus test and the state requires collection for your product or service. Track gross receipts and transaction counts by state and register as soon as you meet the trigger.

Q: Do marketplaces collect tax for subscription sales?
A: Some marketplace facilitators collect and remit sales tax, but coverage depends on the platform and the state’s law. Review the marketplace’s policy and state rules to confirm whether you’re still responsible.
