What payroll deadlines should employers track?

Payroll Tax Deadlines for Employers in New Hampshire

Employers operating in New Hampshire must stay on top of several payroll tax deadlines to ensure compliance and avoid penalties. While New Hampshire does not impose a state income tax or state-level unemployment tax, federal payroll tax obligations remain in effect.

Key Payroll Tax Deadlines

• Federal Payroll Tax Deposits: Employers must deposit federal income tax withheld, Social Security, and Medicare taxes according to the IRS deposit schedule. This can be semi-weekly or monthly depending on the amount of payroll tax liability.
• Quarterly Federal Tax Returns (Form 941): Employers must file Form 941 to report federal payroll taxes withheld and paid. Deadlines are typically April 30, July 31, October 31, and January 31, following the end of each calendar quarter.
• Annual Federal Unemployment Tax Return (Form 940): This form is due by January 31 each year to report federal unemployment tax, if applicable.
• New Hampshire Employment Security (NHES) Reporting: Although New Hampshire does not charge unemployment insurance taxes, employers must report new hires to the NH New Hire Reporting Program within 20 days of hire. This supports federal and state compliance efforts.

Operational Considerations

• Recordkeeping: Maintain accurate payroll records including tax deposits, filings, and employee wage information for at least four years.
• Automation: Use payroll software or service providers that track federal deadlines and automate tax deposits and filings to reduce errors.
• Employee Classification: Properly classify workers as employees or contractors to ensure correct payroll tax treatment.
• Compliance Monitoring: Regularly review payroll processes and IRS updates to stay current on any changes to deposit schedules or filing deadlines.

As of 2026, employers in New Hampshire should prioritize federal payroll tax deadlines and new hire reporting requirements to maintain smooth business operations and compliance.
