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 is found in RSA 78-D, specifically the addition of section 78-D:2-a, which emphasizes the autonomy of New Hampshire businesses in relation to foreign tax collection. It cites Part I, Article 12 of the New Hampshire Constitution, asserting that residents are only subject to laws they have consented to, thereby reinforcing the principle of local control over tax obligations.

The bill also specifies that New Hampshire retailers will not be required to collect sales or use taxes for foreign governments or assist in the collection of these taxes unless mandated by Congress under the Commerce Clause or by state law. The effective date for this 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 this bill primarily introduces new provisions rather than altering or removing existing ones.
