Quick Answer
Determining multistate compliance obligations requires four analyses: (1) nexus determination in each state; (2) tax type analysis (sales / income / payroll / franchise); (3) threshold verification and documentation; and (4) registration and ongoing compliance plan. The short version is that compliance determination is a state-by-state, tax-type-by-tax-type exercise. In our experience, the best approach is a systematic compliance map maintained and updated as the business changes.1

Four steps to determine multistate compliance.
The Four Compliance Determination Steps
| Step | Analysis2 |
|---|---|
| Nexus | Physical / economic / affiliate |
| Tax Type | Sales / income / payroll / franchise |
| Threshold | Verify triggers met |
| Plan | Registration + ongoing |
1. Nexus Determination
State-by-state nexus analysis.
If this is you: Multi-state business. Each state's nexus rules. Physical presence + economic thresholds. Apply per-state.
Nexus Strategy
- Inventory activities by state.
- Identify physical presence.
- Measure economic thresholds.
- Check affiliate / marketplace.
- Document analysis.
2. Tax Type Analysis
Each tax type analyzed separately.
If this is you: Nexus state may have different rules for different taxes. Sales tax, income tax, payroll, franchise. Each requires separate analysis and compliance.
3. Threshold Verification
Verify trigger thresholds met.
If this is you: Economic thresholds evaluated. $500K CA sales tax. $711K CA income (Factor Presence). Other states vary. Annual measurement.
4. Registration and Compliance Plan
Systematic state-by-state plan.
If this is you: Multi-state exposure identified. Registration plan. Software selection. Periodic review cadence. Professional engagement where complex.

Systematic compliance analysis prevents six-figure exposure. Professional determination pays for itself.
Dealing with Multistate Tax Exposure?
Multistate obligations don’t announce themselves — most businesses accumulate sales tax, income tax, or payroll tax exposure in other states without realizing it until they’re contacted or audited. If you’re selling across state lines, have remote employees, or aren’t sure where your business has nexus, a brief review can identify where you have exposure and what to do about it.

Frequently Asked Questions
How do I determine compliance?
Four-step analysis — nexus per state, tax type per state, threshold verification, compliance plan. Systematic approach required for multi-state businesses.
Is nexus the same for all taxes?
No. Sales tax nexus ≠ income tax nexus ≠ payroll nexus. Each tax type separate analysis. PL 86-272 protects income only.
What triggers physical nexus?
Office, employees, inventory, property, regular business presence. Even single day of activity can trigger in some states.
What is economic nexus?
Post-Wayfair sales / transaction thresholds. $500K CA sales tax. $711K CA income. Other states vary. Measured annually.
Should I ever deregister?
Sometimes. If truly no nexus and no ongoing activity. Formal deregistration process.
How often should I analyze?
Annual minimum. Quarterly for growth businesses. Continuous monitoring via software for thresholds.
What about new state expansions?
Analyze before activity. Proactive nexus determination. Register before triggering thresholds.
Can I use state nexus questionnaires?
Reviewing but not completing is best. Completing commits you to analysis. Attorney-guided response preferred.
What's MTC matrix?
Multistate Tax Commission comparison of state nexus rules. Updated periodically. Useful reference.
Do I register in every state?
Only nexus states. Analyze carefully. Registration creates ongoing obligations.
What about back-year exposure?
Analyze historical activity. VDA often optimal resolution. Limited look-back vs. unlimited non-filer.
How long does analysis take?
Varies with complexity. Single-state: hours. Multi-state 10+ states: days / weeks. Updates simpler after initial.
Do I need an attorney?
Complex or controversy matters: yes. Routine compliance: CPA often sufficient. Attorney for privilege and strategy.
