Missouri has established specific tax regulations for both resident and nonresident remote employees. Here’s a concise overview:
-
Employer Withholding Obligations: Employers in Missouri must deduct and withhold taxes from the wages paid to employees, whether residents or nonresidents. For remote employees, the determination of amounts to withhold is subject to regulations prescribed by the Director of Revenue. This ensures that the amount withheld is approximately equivalent to the estimated tax due on the employee's wages.
-
Sourcing Nonresident Wages: Nonresident employees' wages are sourced based on income derived from activities conducted within Missouri. Specifically, a nonresident individual's adjusted gross income consists of income, gain, loss, and deductions that originate from Missouri sources as outlined in the tax laws.
-
Reciprocity Agreements: Currently, Missouri does not have reciprocity agreements with any states regarding the withholding of income taxes for nonresident employees. This means that nonresident employees working remotely in Missouri are subject to its withholding requirements, regardless of their home state tax obligations.
-
De-minimis Threshold: There is a de-minimis threshold that stipulates a minimum earning level for nonresidents. A nonresident individual must have adjusted gross income derived from Missouri sources of at least $600 to be required to file a tax return and potentially have taxes withheld.
-
Local/City Wage Taxes: Missouri imposes local wage taxes, particularly in areas like Kansas City and St. Louis, where specific earnings taxes apply. Employers located in these jurisdictions must comply with additional local tax obligations when processing wages for employees working in those cities.
Overall, Missouri's tax framework for remote employees mandates strict adherence to withholding requirements without established reciprocity, while local taxes further complicate wage tax responsibilities for employers.
