Many people ask about the 9% NH Rooms and Meals tax, so here is a quick explanation.
If you decide to offer your vacation up for short-term vacation rentals (185 days or less), those rentals are subject to a 9% tax (Meals and Rooms tax) that is paid to the state of New Hampshire. Owners must obtain a license (which you can get get here) and submit your tax reports monthly (which is done online).
If you rent your home for a longer period of time (186 days or more), the rental is not subject to that tax. If you start a rental that is subject to the tax & the dates extend, you can file for a refund for any taxes paid.
