Sales tax exposure is one of the most misunderstood areas of compliance. Most businesses do not realize exposure exists until filing, audits, or notices force the issue. By then, options are narrower and costs are higher.
This hub explains what sales tax exposure is, how it develops, when it becomes a risk, and how growing businesses should approach it before filing decisions are made.
What is sales tax exposure
Sales tax exposure is potential liability resulting from uncollected or unpaid sales tax or use tax.
Exposure can include:
- Uncollected sales tax
- Unpaid use tax
- Penalties
- Interest
- Reporting obligations
Exposure does not automatically mean tax is owed, but it always requires review.
Why sales tax exposure exists
Exposure exists because tax obligations often arise before businesses realize they exist.
Common causes include:
- Crossing economic nexus thresholds
- Hiring employees in new states
- Expanding products or services
- Adding marketplaces or platforms
- Untaxed purchases
- System fragmentation
Exposure accumulates quietly as businesses grow.
Core sales tax exposure concepts
These foundational guides explain the building blocks of exposure.
When exposure becomes a real risk
Not all exposure requires immediate action.
Risk increases when:
- Thresholds are crossed
- Multiple states are involved
- Exposure spans multiple years
- Filing has begun incorrectly
- Audits are likely
- Transactions increase in volume
Understanding timing matters as much as understanding amounts.
When sales tax exposure becomes a risk
What happens if exposure is ignored

It increases:

Why legacy tools miss exposure
Many tax platforms are built for calculation and filing, not exposure analysis. This creates blind spots that grow over time.
What comes after exposure is identified
Exposure clarity enables better decisions.
After exposure is identified, businesses can:
- Prioritize jurisdictions
- Plan remediation
- Choose filing strategies
- Engage advisors with clarity
- Scale compliance intentionally
