Why Payroll Compliance Matters
Of all the compliance obligations a US business faces, payroll is among the most unforgiving. The IRS and state agencies impose strict deadlines and significant penalties for late deposits, incorrect withholding, and missed filings. For foreign-owned US entities that hire their first US employee, this is often the area that generates the first compliance crisis.
Understanding the full stack of payroll obligations before you make your first hire is essential.
Federal Payroll Tax Obligations
Income Tax Withholding (Federal)
Employers must withhold federal income tax from employee wages based on the employee's Form W-4 (Employee's Withholding Certificate). The withholding amount is determined by the employee's filing status, allowances, and any additional amounts elected.
FICA Taxes
The Federal Insurance Contributions Act (FICA) taxes fund Social Security and Medicare.
|-----|--------------|--------------|-----------------|
Employers match the employee's Social Security and Medicare contributions. The combined employer-employee FICA cost is 15.3% up to the Social Security wage base, then 2.9% (Medicare only) above that.
Federal Unemployment Tax (FUTA)
Employers pay FUTA at 6% on the first $7,000 of each employee's wages. However, if you pay state unemployment taxes (SUI), you receive a credit of up to 5.4%, reducing the effective FUTA rate to 0.6% in most states.
Payroll Deposit Schedule
The IRS assigns employers to a deposit schedule based on their total tax liability over a lookback period:
Missing deposit deadlines triggers automatic penalties:
Quarterly and Annual Filings

State Payroll Compliance
Every state where you have employees has its own payroll requirements, including:
For companies with employees in multiple states, payroll compliance multiplies. You must register as an employer in each state where employees work, withhold the correct state income tax, and file state payroll returns on that state's schedule.
Classifying Workers: Employee vs. Independent Contractor
One of the most consequential payroll decisions is how you classify workers. The IRS uses a multi-factor test (behavioral control, financial control, type of relationship) to determine whether a worker is an employee or an independent contractor.
Employees: You withhold income taxes and FICA, pay employer FICA and FUTA, and are subject to all employer obligations.
Independent contractors: You do not withhold or pay payroll taxes. The contractor is responsible for self-employment tax. You issue Form 1099-NEC if you pay $600 or more during the year.
Misclassification risk: If the IRS determines you misclassified an employee as a contractor, you owe back taxes, penalties, and interest for all periods of misclassification. State agencies (particularly California's EDD) conduct their own audits with even more aggressive standards.
Payroll for Foreign Nationals Working in the US
If you employ foreign nationals in the US (H-1B, L-1, O-1, or other visa holders), US payroll tax obligations apply to their US wages. However:
India and the US do not currently have a social security totalization agreement, so Indian nationals working in the US are generally subject to full FICA.
