New Hampshire does not levy a general sales tax or personal income tax, but it does impose business taxes on organizations operating in the state. The two major taxes are the Business Enterprise Tax (BET) and the Business Profits Tax (BPT). The BET applies to all entities, including corporations, partnerships, proprietorships, fiduciaries, trusts, non-profits, and LLCs, based on the enterprise value tax base. The BPT applies to business organizations with gross business income exceeding USD 92,000, with rates set at 7.6% for 2022 and 7.5% for 2023 onwards.
Both taxes require timely filing, estimated payments, and compliance with due dates. Penalties and interest are imposed for non-compliance, while extensions are available under specific conditions.
This blog explains the BET and BPT in detail, including rates, filing deadlines, extensions, estimated payments, penalties, and interest obligations.
