Unit
- Employer tax responsibilities: Employers must withhold and remit federal income tax, Social Security and Medicare taxes (FICA), and federal unemployment tax (FUTA). State taxes vary by jurisdiction.
- Federal income tax withholding: Based on Form W-4 completed by the employee. Employers use IRS tables or percentage methods to compute withholding amounts, adjusting for allowances and filing status.
- FICA taxes: Social Security tax rate is 6.2% on wages up to the annual wage base limit; Medicare tax is 1.45% on all wages, with an additional 0.9% on high earners (employer matches both except additional Medicare).
- FUTA tax: 6.0% on first $7,000 of wages per employee, but most states offer credits reducing the effective rate to 0.6%. FUTA funds state unemployment agencies.
- Deposit requirements: Payroll taxes must be deposited electronically via EFTPS. Deposit frequency (monthly or semi-weekly) depends on prior tax liability.
- Penalties for noncompliance: Failure to deposit or pay taxes on time can result in penalties ranging from 2% to 15%, plus interest. Trust fund recovery penalties apply to willful nonpayment.
- Recordkeeping: Maintain employment tax records for at least four years, including payroll registers, tax returns, and employee source documents.
- Quarterly and annual reporting: File Form 941 quarterly (or Form 944 annually for small employers) and Form 940 annually for FUTA. Provide Form W-2 to employees and Social Security Administration.
- State and local tax compliance: Employers must register with state and local tax authorities where employees work and reside. State income tax withholding rates vary by jurisdiction, and some states have reciprocal agreements with neighboring states to simplify withholding for cross-border employees. Employers must file state specific wage and tax reports, often on a quarterly or monthly basis, and remit withheld amounts to the appropriate agency. Failure to register or file can result in penalties and interest.
- Worker classification: Employers must correctly classify workers as employees or independent contractors using IRS common law factors that focus on behavioral control, financial control, and the type of relationship. Misclassification can lead to liability for unpaid federal income tax withholding, FICA, and FUTA, plus penalties and interest. Form SS 8 can be submitted for a formal determination from the IRS.
- Payroll tax credits and adjustments: Employers may be eligible for credits such as the Work Opportunity Tax Credit for hiring targeted groups or the Employer Credit for Paid Family and Medical Leave. Adjustments to previously filed returns are made using Form 941 X, and amended state returns may be required. Proper documentation is essential to support claimed credits and avoid disallowance.
- Multi state employment tax issues: When employees work in multiple states or telecommute, employers must navigate nexus rules, state unemployment tax thresholds, and withholding obligations. Some states follow a physical presence standard while others use economic nexus. Employers should track days worked in each state and file accordingly to prevent double taxation and minimize penalty exposure.
