As more Phoenix-based businesses grow beyond state lines—whether through remote hires, online sales, or service expansion—many unknowingly trigger multi-state tax nexus. If your business has customers, employees, or contractors in other states, you may be on the hook for sales tax, income tax, or payroll obligations far beyond Arizona.
At Concierge Consulting & Accounting, PLLC, we help businesses across Phoenix understand and manage their multi-state nexus risk. Here’s what you need to know to stay compliant and avoid unexpected penalties.
What Is Nexus?
Nexus is a legal connection between your business and a state, giving that state the authority to tax your company. Nexus can be created by:
- Having a remote employee or contractor working in that state
- Selling products or services over a certain dollar or transaction threshold
- Storing inventory in a warehouse (including Amazon FBA)
- Attending trade shows or operating short-term projects
With the rise of remote work and online commerce, many Phoenix businesses now have multi-state exposure without even realizing it.
Common Ways Phoenix Businesses Trigger Out-of-State Nexus
1. Remote Employees
If you have employees working from home in other states, you may owe:
- Payroll taxes in that state
- State income tax withholding
- Unemployment insurance (SUTA) registrations
2. Online Sales
Many states enforce economic nexus laws, requiring out-of-state sellers to collect and remit sales tax once they hit a certain threshold.
Example:
Selling more than $100,000 or 200 transactions per year into California can trigger sales tax obligations—even if you don’t have a physical presence there.
3. Contractors and Affiliates
Hiring 1099 contractors in other states, or working with marketing affiliates, can also create nexus depending on local laws.
How Nexus Affects Arizona-Based Businesses
Even if you’re incorporated in Arizona and primarily operate in Phoenix, you could still owe:
- Sales tax in states with economic nexus thresholds
- State income or franchise taxes in places where you have employees or inventory
- Annual business filings or fees
Failure to register and comply can result in:
- Late filing penalties
- Interest on unpaid taxes
- Back taxes for multiple years
- Jeopardized funding, licensing, or M&A transactions

FAQs: Multi-State Nexus for Phoenix Businesses
How do I know if I have economic nexus?
Each state has different rules. We’ll analyze your sales volume and transaction count by state to determine exposure.
Do remote workers always create nexus?
Usually, yes—especially if they’re employees. Some states even count long-term contractors toward nexus.
What if I haven’t filed in a state I now have nexus in?
We can help with voluntary disclosure agreements or backfiling to reduce penalties and get you back in good standing.
