New Hampshire LLC vs. S-Corp: Entity Selection Under BPT and BET State Tax Rules

When structuring a business in cities like Concord, Portsmouth, or Manchester, entrepreneurs must navigate a complex web of tax obligations. While federal tax strategies often dictate entity choice, New Hampshire's unique state tax system changes the calculation entirely. Unlike most states that simply mirror federal pass-through taxation rules, this state imposes distinct taxes directly on the business entity itself.

Understanding the interplay between federal rules and state statutes is critical. A strategy that saves thousands at the federal level might not provide any relief locally. This guide explores the critical differences between a standard Limited Liability Company and one that has elected S-Corporation status, specifically focusing on state-level tax implications.

Pass-Through Taxation Realities in New Hampshire

At the federal level, a standard multi-member LLC is taxed as a partnership. Profits 'pass through' to the owners' personal tax returns, and the entity pays no federal income tax. However, the New Hampshire Department of Revenue Administration, Concord treats business taxation very differently.

The Business Profits Tax (BPT)

Under N.H. Rev. Stat. Ann. § 77-A:2, the state assesses a Business Profits Tax on income derived from conducting business activity within its borders. Both standard LLCs and S-Corps are subject to the BPT at the entity level. This means that before profits can 'pass through' to your personal federal return, the business itself must pay a percentage of its taxable business profits directly to the state.

The Business Enterprise Tax (BET)

Additionally, N.H. Rev. Stat. Ann. § 77-E:2 establishes the Business Enterprise Tax. The BET is a tax on the enterprise value tax base, which essentially includes the total amount of compensation paid to employees, interest paid, and dividends distributed. Like the BPT, the BET applies uniformly to both LLCs and S-Corps. Because the state does not have a traditional personal income tax on earned wages, the BPT and BET serve as the primary methods for taxing commercial activity.

Net Tax Thresholds for BET/BPT Filing Obligations

Not every small business is immediately liable for these taxes. The state provides specific thresholds, and your entity is only required to file Form BT-Summary, New Hampshire, Department of Revenue Administration, Business Tax Return Summary if it exceeds these limits.

• BPT Threshold: Businesses must file a BPT return if their gross income from all activities exceeds $109,000 during the taxable period.
• BET Threshold: Businesses must file a BET return if their gross receipts exceed $298,000 OR if their enterprise value tax base (compensation, interest, and dividends) exceeds $298,000.

These statutory limits are periodically adjusted for inflation. It is possible for a business to be liable for the BET even if it operates at a loss and owes no BPT, simply because it paid out salaries or dividends.

Self-Employment Tax Mitigation via S-Corp Election

If state taxation is virtually identical for both structures, why do many local business owners choose an S-Corp? The answer lies at the federal level with the Internal Revenue Service, Manchester (local field office).

By default, all net profits of a standard LLC are subject to federal self-employment taxes (Medicare and Social Security), which total roughly 15.3%. However, by filing Form 2553, FED, Internal Revenue Service, Election by a Small Business Corporation under 26 U.S.C. § 1362, an LLC can elect to be taxed as an S-Corp.

In an S-Corp, the owner is treated as an employee and paid a 'reasonable salary'. Self-employment taxes only apply to that salary. The remaining net profits can be distributed as dividends, which are generally free from federal self-employment tax. While this federal tax loophole is highly advantageous, you must remember that those dividend distributions will still factor into your state-level BET calculation.
