One of the most common questions growing businesses ask is simple on the surface and complex in reality.
Do we have sales tax nexus in multiple states?
Many businesses answer this question based on instinct, fear, or incomplete information. Others assume that selling nationally means obligations exist everywhere.
Neither approach is reliable.
Selling in multiple states does not equal nexus everywhere
Selling across state lines is common. Nexus is not. Nexus depends on specific triggers, not geographic reach.
A business can:
- Sell into all 50 states
- Have customers nationwide
- Operate entirely online
And still only have nexus in a limited number of states. The key is identifying where legal thresholds have actually been crossed.
Why guessing creates unnecessary risk
When businesses guess, they often:
- Register in states where no obligation exists
- Begin filing unnecessarily
- Create administrative burden
- Increase long-term compliance costs
- Signal activity that draws scrutiny
Guessing rarely reduces risk. It usually shifts it.

How nexus actually spreads across states
Nexus accumulates through specific activities, not general growth.
Common multi-state triggers include:
- Exceeding economic thresholds in certain states
- Hiring remote employees
- Using third-party warehouses or fulfillment centers
- Storing inventory through marketplaces
- Providing taxable services across jurisdictions
- Participating in in-state projects or installations
Each of these triggers applies differently by state.
Why spreadsheets and intuition fail
Many teams rely on:
- Sales summaries
- Revenue totals
- State counts
- Payment processor dashboards
These tools are not designed to evaluate nexus.
They often miss:
- Transaction count thresholds
- Timing of threshold crossings
- Indirect physical presence
- Marketplace nuances
- Product and service taxability differences
As a result, they produce false positives and false negatives.
Marketplace activity complicates nexus
Marketplaces may collect tax on certain transactions, but that does not eliminate nexus automatically.
Businesses can still have:
- Registration requirements
- Reporting obligations
- Use tax exposure
- Nexus from non-marketplace activity
Marketplace collection reduces some risk, but it does not remove the need for analysis.
SaaS and services add another layer
Digital products and services create additional complexity. Taxability varies widely by state.
A business may:
- Exceed economic thresholds
- Have nexus
- But sell non-taxable services in certain states
Without taxability analysis, nexus conclusions are incomplete.
Why multi-state nexus should be evaluated state by state
There is no universal rule.
Each state has:
- Different thresholds
- Different definitions
- Different enforcement priorities
- Different interpretations
Multi-state nexus is not a single determination. It is a collection of state-specific conclusions.
How experienced teams determine multi-state nexus
Experienced teams do not ask “Do we have nexus everywhere?”
They ask:
- Which states show potential triggers
- How those triggers were created
- When thresholds were crossed
- Whether activity is taxable
- Whether exposure exists
- Whether action is required
This turns uncertainty into a manageable list.
Nexus does not require immediate registration everywhere
Discovering nexus in multiple states does not mean filing everywhere at once.
It means:
- Prioritizing states
- Evaluating materiality
- Sequencing action
- Preserving optionality
This prevents rushed decisions.
Multi-state nexus is a diagnostic exercise
Determining where nexus exists is not a compliance commitment. It is an analysis step that enables better decisions. Businesses that take this step avoid unnecessary filings and reduce long-term risk.
Guessing is optional
Sales tax nexus is complex, but it is not unknowable.
With the right framework, businesses can determine where obligations actually exist and where they do not. Clarity replaces fear when guessing is removed.
