New Hampshire does not impose a state income tax on wages. Only federal taxes and FICA apply.
Federal withholding uses the official 2026 IRS Publication 15-T Percentage Method tables. Supports both 2019-and-earlier W-4 (allowance-based) and 2020+ W-4 (Steps 2–4). Federal withholding allowance: $4,300. Social Security wage base: $176,100.
To estimate your New Hampshire take-home pay: start with gross pay, subtract federal income tax (using IRS Pub 15-T 2026 brackets), subtract Social Security (6.2% up to $176,100) and Medicare (1.45%), and any other deductions. Use the calculator above for a quick estimate.
No. New Hampshire does not levy a state income tax on wages. Employees in New Hampshire only have federal income tax and FICA (Social Security and Medicare) withheld from their paychecks.
The 2026 Social Security wage base is $176,100. Employees pay 6.2% of wages up to this limit. Earnings above $176,100 are not subject to Social Security tax, though Medicare tax of 1.45% (plus 0.9% surtax over $200,000) applies to all wages.
For 2026, the IRS Publication 15-T Standard Withholding percentage method for a single filer uses annualized wages: 0% up to $7,500; 10% from $7,501 to $19,900; 12% from $19,901 to $57,900; 22% from $57,901 to $113,200; 24% from $113,201 to $209,275; 32% from $209,276 to $263,725; 35% from $263,726 to $648,100; and 37% above $648,100. These thresholds include the standard deduction and were updated for 2026 inflation adjustments.
The IRS updates federal withholding tables annually in Publication 15-T, typically released in December for the following year. State withholding tables vary by state — some update annually, others less frequently. Always verify you are using current-year tables before processing payroll.
