For state income tax withholding, the primary rule is typically to withhold for the state where the employee physically performs the work (the ‘source’ of the income). While reciprocity agreements and resident/non-resident rules come into play, the work location is the starting point for determining tax jurisdiction.

Processing payments outside the normal cycle requires strict adherence to internal controls. The payroll professional must first consult and follow the company’s established written policy, which should outline authorization requirements. This ensures consistency, prevents unauthorized payments, and maintains audit trails.

Timely and accurate deposit of employee deferrals is a critical ERISA requirement. The immediate action must be to halt the erroneous transmission and identify the root cause within the payroll system (e.g., a calculation error, timing issue, or data export flaw). This prevents a compliance failure and ensures the correct funds are remitted.

An employee working from another country can create a ‘permanent establishment’ for the company, triggering corporate tax, payroll tax, and legal obligations in that foreign jurisdiction. This is a complex area requiring consultation with international tax and legal experts. The other options are operational details, not primary compliance risks.

IRS rules state that an employer must implement a new Form W-4 for withholding purposes no later than the first payroll period ending on or after the 30th day from the date the form was received. This provides a reasonable administrative window for processing while ensuring timely compliance with the employee’s updated withholding requests.

Providing the ACH trace number (also called a Trace ID or Transaction ID) empowers the employee and their bank to locate the specific transaction within the banking system. This is a standard, professional practice for investigating missing direct deposits and moves the inquiry to the appropriate financial institutions efficiently.

Under the Fair Labor Standards Act (FLSA), the employer has the ultimate responsibility to ensure non-exempt employees are paid for all hours worked. This requires implementing a system (like a time clock or online tracker) for employees to record time, and the employer must compensate based on those records. The employer cannot ignore work it knows or has reason to believe was performed.

Unless the benefit qualifies for a specific statutory exclusion (which a cash home office stipend generally does not), it is considered supplemental wages. Its value must be included in the employee’s gross taxable wages in the applicable pay period, subject to federal/state income tax withholding and FICA taxes, and reported on the Form W-2.

The employer is responsible for accurate reporting and withholding. The proper course is to stop the error, issue corrected documents (W-2c) to the employee and states, and initiate the process to recover taxes withheld for the wrong jurisdiction and remit them to the correct one. This demonstrates good faith compliance and assists the employee.
