How can we help?

Find your New Hampshire tax account info

If you've run payroll in New Hampshire previously, you can find your NHES Employer Number on notices received from the NHES such as the Letter of Determination or Quarterly Tax and Wage Report. You can also call the agency to obtain your number at (603) 228-4038. 

UI Tax Rate

Your UI Tax Rate will appear on the Tax Rate Determination letter that you received from NH Employment Security. Typically, NH Employment Security will establish new rates in July, but it also can update rates in any given quarter. You'll also be assigned an Administrative Contribution rate (AC rate) between 0.1% and 0.4%–do not enter this as part of your unemployment rate in Gusto. If you’re unsure of your rates, verify by calling the agency at (603) 224-3311. 

Your UI Tax Rate generally changes each year, effective July 1st. However, this New Hampshire tax agency can update assigned rates quarterly, dependent upon the agency's needs. When you receive a new rate from New Hampshire, update your rate in Gusto with the correct effective date.
