For a technology services company registered in Texas and operating across the United States, the concept of a “borderless” business is a reality. However, state tax authorities view borders very differently. Whether you are providing SaaS, custom software development, or IT consulting, you are likely entangled in a web of tax obligations known as Nexus.
Understanding nexus is no longer just a concern for “Big Tech”—it is a foundational compliance requirement for every growing software firm.
What Is “Nexus”?
In simple terms, Nexus is the “minimum connection” a business must have with a state before that state can legally impose tax obligations on it. If you have nexus in a state, you may be required to:
- Collect and remit Sales Tax.
- Pay Franchise or Income Tax.
- File annual business reports.
1. Physical Presence Nexus: Beyond Brick and Mortar
Traditionally, nexus required a physical office. Today, for technology companies, it is triggered by “People and Property.”
Common Triggers for Tech Companies:
- Remote Employees: Having even one software engineer working from their home in Virginia or Colorado creates physical nexus in that state.
- Property & Equipment: This includes owning or leasing servers, laptops provided to remote staff, or data center space.
- On-Site Services: Sending a technician to a client’s site in Oklahoma for software installation or training establishes nexus there.
- Independent Contractors: Using third-party agents or “1099” contractors to solicit sales or perform services on your behalf.
Texas Example: A software company based in Austin sends a developer to a client in Dallas. While both are in Texas, if that developer later travels to New Mexico to customize a local server, the company has established physical nexus in New Mexico, triggering potential tax filings there.
2. Economic Nexus: The New Frontier
Since the landmark 2018 Supreme Court case South Dakota v. Wayfair, Inc., states can impose sales tax obligations based solely on your economic activity, regardless of physical presence.
States set specific “Safe Harbor” thresholds. If your sales exceed these amounts, you must register and collect tax.
2025–2026 Key State Thresholds
| State | Dollar Threshold | Transaction Threshold | Threshold Type |
| Texas | $500,000 | None | Dollar Only |
| California | $500,000 | None | Dollar Only |
| New York | $500,000 | 100 | Both must be met |
| Florida | $100,000 | None | Dollar Only |
| Illinois | $100,000 | None (as of 2026) | Dollar Only |
| Most Others | $100,000 | 200 | Dollar or Transaction |
3. Impact on Tax Obligations
Franchise Tax (The “Doing Business” Tax)
Texas imposes a franchise (margin) tax on any entity “doing business” in the state. This includes deriving receipts from Texas activities or having employees in the state. Even if you are a Delaware Corp, if your principal place of business is Texas, you are subject to this tax.
Sales and Use Tax
Technology services are often taxable, but rules vary wildly by state.
- SaaS: Generally taxable in Texas (with a 20% exemption—you only pay tax on 80% of the bill).
- Custom Software: Often exempt if delivered electronically, but taxable if delivered on physical media.
Income Tax
Many states use “factor-based” standards. If your payroll or property in a state exceeds a certain amount, you may owe corporate income tax even without an office.
4. IT Consulting & Professional Services: The “Bundling” Trap
A significant risk for Texas tech companies is the taxable bundle. Generally, professional services like advisory work or system design are not taxable in Texas. However:
- Advisory/Consulting: Not taxable.
- SaaS/Data Processing: Taxable.
The Danger: If you bill a client $10,000 for “Software Implementation & Subscription” as a single line item, Texas may tax the entire $10,000.
The Solution: Always itemize. List your exempt consulting services separately from taxable software licenses. In Texas, if the taxable portion exceeds 5% of a bundled invoice, the whole invoice is presumed taxable unless clearly separated.
Practical Guidance for Compliance
- Audit Your “Human Map”: Keep a live record of exactly where your remote employees and contractors are located.
- Track Sales by Destination: Monitor your revenue totals for every state to ensure you don’t accidentally cross an economic nexus threshold.
- Register Promptly: Once nexus is established, register with that state’s Comptroller or Department of Revenue to avoid back-taxes and penalties.
- Use Tax Automation: For multi-state operations, manual tracking is nearly impossible. Consider software like Avalara or TaxJar to automate state-specific tax rates.
Conclusion
For a Texas-based technology firm, the “borderless” nature of our industry is a competitive advantage, but it requires a disciplined approach to tax compliance. By understanding where your people, property, and sales “touch” other states, you can scale your business without the fear of a surprise audit.
