Tax Computations for NH Businesses

Businesses in New Hampshire are subject to a number of taxes.  It is important that taxes not only be paid on a timely basis, but that they are also planned for properly in advance.  In addition to withholding (and submitting to the taxing authorities) employee's taxes from employee paychecks, employers are also liable for additional taxes on employee compensation.  Employers who have employees residing in other states should also consider the tax consequences of such employment.

Depending on the type of legal business entity your business is operating under, you may also have additional personal or business tax liabilities.  The nature of your business will also dictate other tax liabilities for which you may be subject.  While most of the taxes shown below are the legal responsibility of the business to report and to pay to the appropriate taxing authority, many of the taxes should be collected from the businesses' customers at the time of sale.  The fact that you do not collect the appropriate taxes from your customers will not remove your liability to pay said taxes to the taxing authority!  Even if you do not collect the correct amount of taxes from your customers, you will still be responsible to pay them to the taxing authority.  This can be an extremely devastating mistake.  Be sure to seek professional tax advice.

Because of the complexity of tax matters, all SCORE clients are advised to seek professional advice from a registered Certified Public Accountant (CPA) and/or a licensed attorney specializing in tax law.  Seacoast Chapter 185 provides a registry of Local Resources which contains information on accountants, lawyers, and other useful business resources.

While all reasonable efforts have been made for accuracy, the following list should be considered a guideline for planning and budgeting purposes.  SCORE makes no representations as to the accuracy or completeness of the below information, nor does SCORE guarantee that these rates or payment schedules have been updated as tax laws and rates may change.  The information contained below was compiled in most part from
