What is Multistate tax nexus?
Multistate tax nexus refers to the sufficient connection between a taxpayer and two or more states that creates income tax filing obligations in those jurisdictions. Remote workers establish nexus through either domicile in their resident state or physical presence while performing services in nonresident states. States assert nexus over residents who maintain their primary residence within the state's borders, taxing worldwide income regardless of where it is earned. Nonresident nexus typically arises when individuals perform services within a state's borders, creating obligations to file returns and pay tax on income sourced to that state. The determination of a multistate nexus requires analyzing domicile status, physical presence days in each jurisdiction, and state-specific rules, including convenience-of-the-employer doctrines that may attribute income to states where individuals never physically work. Understanding multistate nexus helps remote workers navigate complex filing requirements and implement strategies through Home office planning and proper income allocation to minimize overall tax liability while maintaining compliance across all applicable state jurisdictions.
