In California, the taxation of wages for both resident and nonresident remote employees follows distinct rules shaped by the state's aggressive tax posture.
Employer Withholding Obligations
California imposes day-one withholding for all wages paid to employees, regardless of their residency status. Employers are required to withhold income taxes on payments to both residents and nonresidents from the first day of employment.
Wage Sourcing for Nonresidents
For nonresident employees, the wages are sourced based on where the services are performed. Specifically, nonresidents are taxed on income derived from California sources, which means that if the work performed by the nonresident qualifies as service conducted in California, those wages are subject to California taxation.
Reciprocity Agreements
California does not have any reciprocity agreements with other states. This means that income earned by nonresidents while working for a California employer will be subject to California taxes without any allowance of income tax credits for taxes paid to their state of residence.
De-minimis Thresholds
There are no de-minimis thresholds in California's tax structure; hence all income earned is subject to withholding from the outset. This applies to both resident and nonresident workers.
Local/City Wage Taxes
Additionally, California does not have local or city wage taxes affecting employee earnings. As a result, employees will only deal with state income tax obligations without the complication of local taxes.
In summary, California's framework for taxing the wages of resident and nonresident employees is characterized by mandatory withholding from the initial wages, a clear sourcing policy for nonresident income, and the absence of reciprocity agreements or de-minimis thresholds, all underscored by a streamlined approach devoid of local wage taxes.
