My client is a data search broker. The company is located in Florida (FL), the client is in Washington, D.C. (DC), and the data supplier is located outside the United States. For example, DC commissions FL to perform data searches; FL sends the request to the overseas supplier (Non-US), who returns the results to FL, and FL then provides the results to its client DC.

DC pays FL for the services, and FL pays the overseas supplier for the information obtained. In which state should FL pay state tax on this income?

Additionally, if FL is setting up a new entity, should it prioritize incorporating in Florida or another specific state?

Basic Determination of State Tax Nexus

State tax liability typically depends on "nexus"—whether a business has sufficient economic or physical connection to the state. This case involves three jurisdictions: Florida, Washington, D.C., and overseas (not involving U.S. state tax).

Florida (FL)

FL is incorporated and operates in Florida, so it has physical nexus in the state. Florida imposes a state corporate income tax, typically at a rate of 5.5% (subject to specific annual adjustments). The service income FL receives from the DC client is business income and should be reported and taxed in Florida unless special apportionment rules apply. Since FL's principal place of business, management functions, and employees are all in FL, this income is typically fully or formulaically apportioned to Florida.

Washington, D.C. (DC)

Whether DC has taxing authority over FL depends on whether FL establishes "economic nexus" in DC. DC has sales tax thresholds for remote sellers or service providers (e.g., annual sales exceeding $100,000 or 200 transactions), but this case involves service income, and DC does not impose a general corporate income tax (DC imposes income tax on businesses and individuals, but non-resident corporations are only taxed if they have source income in DC). FL has no office or employees in DC, only provides services to a DC client, and may not constitute a DC corporate income tax obligation. However, note DC's definition of "source income"—if services are "performed" or "used" within DC, DC-source income may arise. In this case, services are actually performed by FL in FL (sending requests, receiving results), and the DC client only receives the final report, so DC tax risk is low.

Overseas Supplier (Non-US)

The overseas supplier is not subject to U.S. state tax, but when FL pays overseas, it should consider whether withholding tax applies (e.g., U.S. federal tax on royalties or service fees paid abroad), but at the state tax level, this is typically not involved.

New Entity: Key Factors in State Selection

If FL plans to establish a new entity, the choice of incorporation state should consider the following factors:

  • Tax Burden:Florida has no personal income tax, a relatively low corporate income tax rate (5.5%), and no franchise tax. Other states such as Texas (no corporate income tax but has franchise tax), Nevada (no corporate income tax but other fees to consider), and Delaware (well-developed corporate law but higher franchise tax) each have pros and cons.
  • Client Location:If clients are concentrated in DC, it may be necessary to consider registering or qualifying to do business in DC, but DC has higher tax rates (corporate income tax around 8.25%) and increased compliance costs.
  • Supplier Relationships:Overseas suppliers do not create state tax implications, but international tax treaties should be considered.
  • Entity Form:An LLC or S corporation may pass through to the individual level, requiring consideration of the owners' state of residence tax.
  • Operational Convenience:Florida, as a state of incorporation, offers a mature business environment, no state personal income tax, and is friendly to the service industry.

Overall, if FL continues to use Florida as its primary place of operations, the new entity should still be established in Florida to maintain consistency in existing tax treatment. If considering future expansion into DC or high-tax states, the risk of triggering economic nexus should be evaluated, and optimization may be achieved through multi-entity structures or income apportionment rules.

Conclusion and Recommendations

In the current case, FL should report and pay corporate income tax on this income in Florida, as its business entity and operations are in that state. DC and the overseas supplier do not create state tax obligations for FL (unless DC determines economic nexus, which is unlikely). When establishing a new entity, absent special expansion plans, Florida remains a reasonable choice; if planning to serve more DC clients, it is advisable to consult a tax advisor to evaluate DC's "economic presence" rules and consider whether registration in DC is necessary.

Ultimately, state tax issues are highly dependent on specific facts and state law details. It is recommended that the client maintain complete transaction records and consult a state-licensed tax professional for a targeted analysis.
