While New Hampshire does not impose sales tax, this is subject to change in the future. It’s also important to note that many US states and cities have their own sales tax laws. 

It’s also essential to be aware of sales tax nexus laws if you are a business with a substantial sales presence in other states that impose sales tax. Nexus laws refer to the obligation to collect and remit sales tax in states where a business has a significant economic or physical presence.

Each state has the autonomy to define economic nexus thresholds, which might include total sales, transaction count, or both. If your business has customers in other states, be sure to stay informed on the evolving economic nexus laws and requirements in those states.

With no state-level sales tax and only a few exceptions subject to taxation, most businesses in New Hampshire will not need to worry about sales tax compliance. However, if your product falls under one of the exceptions or if you have a presence in other states that require sales tax collection, it’s crucial to stay informed and to consult with tax professionals to ensure you are following all relevant tax laws and regulations.
