This bill establishes that New Hampshire businesses are not obligated to collect sales taxes for foreign jurisdictions unless such a requirement is imposed by either federal law or New Hampshire state law. The new legal language inserted into the existing law specifies that no New Hampshire retailer shall be compelled to collect sales or use taxes for a foreign government or provide information to facilitate the collection of these taxes, unless mandated by Congress or state law. This provision is grounded in the New Hampshire Constitution, which emphasizes that the state's inhabitants are only subject to laws they have consented to.

The bill amends RSA 78-D by adding a new section, 78-D:2-a, which articulates this principle clearly. The effective date of the act is set for 60 days following its passage. The deletion of any existing legal language is not specified in the provided text, indicating that the bill primarily introduces new provisions rather than removing existing ones.
