Delaware's tax treatment of remote employees, both residents and nonresidents, entails specific employer withholding obligations and sourcing rules, with notable complexities.
Employer Withholding Obligations: Employers in Delaware are required to deduct and withhold taxes from the wages paid to both resident and nonresident employees. The State Tax Department establishes withholding tables to guide calculations, ensuring that an appropriate amount is deducted based on the estimated tax liability of employees throughout the year (30 Del. C. 1953, § 1151) [3][1]. Employers must file withholding returns and pay the withheld tax to the Division of Revenue, adhering to prescribed filing frequencies based on the amount of taxes withheld during a lookback period (30 Del. C. 1953, § 1154) [1].
Sourcing Nonresident Wages: For nonresident employees, wages sourced to Delaware are primarily derived from services performed within the state. This includes compensation for work that is directly attributable to a Delaware employer's operations or conducted within Delaware (30 Del. C. 1953, § 1124) [6]. Nonresidents are subject to a tax on their modified Delaware source income, which is calculated similarly to residents but is adjusted based on the portion of income derived from Delaware sources (30 Del. C. 1953, § 1122) [8].
Reciprocity Agreements: Delaware currently does not maintain any reciprocity agreements with other states concerning tax withholding for nonresident wages. Thus, nonresident employees are generally subject to Delaware withholding without offset from their home state's taxes (30 Del. C. 1953, § 1151) [3].
De-minimis Threshold: Delaware employs a convenience-of-the-employer rule, where remote work conducted out-of-state could avoid Delaware taxation if employees are working from home for their convenience rather than the employer’s requirement. However, there isn't a specific de-minimis dollar or day threshold mandated in the current regulations (as specified in the curated facts) [3].
Local/City Wage Taxes: There are local wage taxes imposed in cities like Wilmington. employers must deduct these local taxes alongside state taxes when applicable (Knowledge Graph Data). These local taxes necessitate careful employer compliance to ensure that all applicable taxes are withheld, which can vary by locality.
Overall, Delaware's framework for taxing remote workers involves a combination of obligations, sourcing rules, and local considerations, making it critical for employers to accurately manage tax compliance for remote employees.
