Test 1

Economic Nexus

The Rule:

Most states now require out-of-state sellers to collect sales tax once they exceed certain sales thresholds, regardless of physical presence.

The Threshold:

$100,000 in revenue OR 200 transactions in any single state within a year.

Common Triggers:

  • Selling through your own website to customers nationwide
  • Rapid growth in e-commerce sales
  • Expanding into new markets without tax review

Self-Assessment:

Have you exceeded $100,000 in sales OR 200 transactions in any state where you don't currently collect sales tax?

Test 2

Physical Presence

The Rule:

Physical presence extends beyond buildings to inventory, employees, and contractors.

The Threshold:

$100,000 in revenue OR 200 transactions in any single state within a year.

Common Triggers:

  • FBA or 3PL inventory in another state
  • Remote employees or contractors working from other states
  • Trade show attendance with onsite order-taking

Self-Assessment:

Do you have inventory stored, employees working, or contractors operating in states where you don't currently file?

Test 3

Product Taxability

The Rule:

What's taxable varies dramatically by state. Digital goods, SaaS, and services have inconsistent treatment.

The Danger:

Assuming your product is non-taxable everywhere because it's non-taxable in your home state.

Common Triggers:

  • Selling software, downloads, or streaming services
  • Offering installation, consulting, or professional services
  • Bundling taxable and non-taxable items

Self-Assessment:

Do you sell digital products, SaaS, or services that might be taxable in some states but not others?

Test 4

Marketplace Sales

The Rule:

Marketplace facilitators (Amazon, Etsy, etc.) collect tax on your behalf for marketplace sales, but NOT for your direct sales.

The Danger:

Assuming marketplace collection covers all your obligations, or double-collecting on marketplace sales.

Common Triggers:

  • Selling on Amazon FBA plus your own Shopify store
  • Using multiple marketplaces with different rules
  • Wholesale and retail sales through different channels

Self-Assessment:

Do you sell through marketplaces AND directly through your own website?

Test 5

Past Exposure

The Rule:

Past non-compliance doesn't disappear. States can audit back 3-8 years depending on jurisdiction.

The Danger:

Registering to collect tax going forward can trigger audits of past periods. This requires careful planning.

Common Triggers:

  • Growing business that never had a formal tax review
  • Changing business models without updating tax compliance
  • Acquiring a business with unknown tax history

Self-Assessment:

Have you been selling for more than a year without conducting a sales tax review?
