What Are the Risks Associated With Multistate Commerce?
Key Takeaway
Multistate commerce creates four categories of tax risk: (1) sales / use tax exposure in customer states; (2) income tax on apportioned income; (3) payroll tax on employees working in other states; and (4) franchise / minimum taxes for doing-business states. The short version is that every interstate transaction potentially creates compliance obligations. In our experience, the biggest surprise for growing businesses is the minimum franchise tax (CA $800) applying in every year the business has nexus, regardless of income.1

The ROI Question
Multi-tax exposure can reach six figures quickly. Proactive compliance prevents catastrophic outcomes.
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
What are multistate commerce risks?
Four categories — sales / use tax, income tax, payroll tax, franchise / minimum tax. Each state imposes its own. Nexus drives exposure.
What's the biggest risk?
Depends on business. E-commerce: sales tax. Service providers: income tax. Multi-state employer: payroll. Franchise tax universal where doing business.
Does CA $800 apply everywhere?
CA $800 minimum franchise tax applies in CA. Other states have own minimums. TX franchise tax, DE franchise tax, etc. Varies.
How do I minimize risk?
Proactive nexus analysis, registration where required, professional compliance, VDA for prior gaps.
Does PL 86-272 help?
Protects income tax only for TPP sellers with solicitation-only activity. Doesn’t protect sales tax, payroll, franchise.
What's the cost of compliance?
Varies. Software ($500-$5K annual), multi-state payroll ($100-$500/month), CPA / attorney services variable. Always less than audit exposure.
Are some states easier?
Some states (SD, TX, FL, WA) no income tax. Sales tax universal with few exceptions. Analyze state-by-state.
How do I track obligations?
Avalara, TaxJar, Vertex for sales tax. Multi-state payroll providers. Professional services for income / franchise.
What if I missed registration?

How often do states audit?
Depends on size / risk profile. Random plus targeted. Multi-year audits common. Attorney representation valuable.
