What is the difference between federal and state payroll taxes?

Understanding Federal vs. State Payroll Taxes in New Hampshire

When managing payroll taxes for your business in New Hampshire, it is important to distinguish between federal and state payroll tax obligations. Both types impact your payroll processes but have different scopes and requirements.

Federal Payroll Taxes

• Scope: Federal payroll taxes apply nationwide and are mandated by the federal government.
• Components: These include Social Security tax, Medicare tax (FICA), federal income tax withholding, and Federal Unemployment Tax Act (FUTA) tax.
• Employer Responsibilities: Employers must withhold employee portions of Social Security, Medicare, and federal income taxes, and also pay the employer portion of Social Security, Medicare, and FUTA taxes.
• Reporting: Federal payroll taxes are reported to the Internal Revenue Service (IRS) through forms such as Form 941 (quarterly) and Form 940 (annually).
• Automation: Many businesses use payroll software or services to automate federal tax withholding and reporting to ensure compliance.

State Payroll Taxes in New Hampshire

• No State Income Tax: New Hampshire does not impose a state income tax on wages, so there is no state income tax withholding required for payroll.
• State Unemployment Insurance (SUI): Employers in New Hampshire must pay state unemployment insurance taxes. These are employer-only taxes that fund unemployment benefits.
• Reporting: Employers report and pay SUI taxes to the New Hampshire Employment Security (NHES) department according to their schedule.
• Compliance: Maintaining accurate payroll records and timely SUI tax payments is essential to avoid penalties.

Operational Takeaways

• Payroll Setup: Ensure your payroll system is configured to withhold federal taxes and calculate employer contributions correctly.
• State Tax Focus: Since New Hampshire lacks state income tax, focus on managing SUI tax payments and compliance.
• Recordkeeping: Keep detailed records of payroll tax withholdings and payments for both federal and state requirements.
• Stay Updated: As of 2026, monitor any changes in federal or New Hampshire payroll tax rates or reporting requirements.
