Many businesses assume that state filing obligations follow profitability. That assumption is increasingly unreliable. In today’s state and local tax (SALT) environment, a company can trigger state filing or registration obligations even if it is operating at a loss. This is because states impose tax obligations based on nexus – a sufficient connection with the state – not on net income. As a result, nexus standards and gross receipts, and not net income, now drive most state filing requirements.
This matters most for venture-backed start-ups, SaaS companies, professional service firms, and pass-through entities expanding across state lines. The practical question is no longer only whether the business has taxable income, but whether it has created enough activity in a state to trigger filing, payment, or registration obligations.
Three Nexus Tests That Matter
State nexus generally shows up in three forms.
- Physical nexus exists when a business has people, property, inventory, or other tangible presence in the state.
- Economic nexus exists when receipts or transaction volume exceed a state threshold, even without physical presence.
- Activity-based nexus exists when a business performs specific types of in-state activities that independently create filing obligations.
These concepts overlap, but they are not the same. A business can have economic nexus without offices or employees, and it can have physical nexus even if revenue in the state is modest.
Thresholds Commonly Used By States
Most states use some combination of the following triggers:
- $50,000 to $500,000 of gross receipts sourced to the state;
- 100 or more in-state transactions in some jurisdictions;
- Payroll or property within the state; and/or
- Registration with a state agency or licensing authority.
California is a useful example because its economic nexus threshold for 2025 is $757,070 or 25% of total sales sourced to the state, indexed annually. Other states are lower and may impose obligations far sooner than many businesses expect. Profitability does not eliminate these requirements.
Federal Baseline Versus State Divergence
At the federal level, filing rules are based on the Internal Revenue Code and generally follow entity type and taxable activity. Corporations file Form 1120 when required, and partnerships file Form 1065 under the applicable federal rules. Federal law does not create a gross receipts-based state filing regime.
That distinction is where the SALT issue begins. States are not required to follow the federal model, and many now impose filing obligations based on revenue or activity alone. As a result, a business can be fully compliant federally while still missing multiple state-level filing requirements.
Best Practices for Planning & Risks Businesses Should Know
The best planning in this area is structural. Businesses should implement monthly state-by-state revenue tracking so they can see when thresholds are approaching instead of discovering the problem at year-end.
Other useful controls include:
- Reviewing where receipts are sourced under each state’s rules;
- Tracking payroll and property footprints by jurisdiction;
- Monitoring registration thresholds separately from income tax thresholds;
- Considering voluntary disclosure if prior-year thresholds were exceeded without filing; and
- Reviewing how contracts, personnel, and delivery models affect nexus.
For businesses with multiple revenue streams, classification matters too. A state may treat one activity as taxable while another is not, so a one-size-fits-all filing analysis can easily miss nuances.
The most common compliance failures are predictable.
- Assuming no filing is required because the business is not profitable;
- Waiting until year-end to assess nexus;
- Misapplying sourcing rules;
- Failing to register after crossing a threshold; and
- Ignoring prior open years once nexus is established.
When a business fails to file, this can lead to late filing penalties and interest. Exposure can accumulate quickly, especially for fast-growing companies that cross multiple state thresholds before anyone notices.
Key Takeaways
- State filing obligations increasingly arise from nexus and receipts, not profitability.
- Physical nexus, economic nexus, and activity-based nexus are separate triggers.
- Many states use thresholds in the $5,000 to $500,000 range, but the rules vary.
- California’s economic nexus threshold is indexed and should be reviewed annually.
- Proactive monthly monitoring and sourcing review are the best ways to control exposure.
Final Thoughts
State tax compliance is no longer a simple function of profit. A business can be unprofitable and still create filing obligations in multiple states based on revenue, activity, or physical presence.
If your company is expanding across state lines or approaching a new threshold, the right time to review nexus is before a filing notice or audit letter arrives. Contact our team today to discuss your state filing exposure.
