Understanding LLC Taxation Basics
How New Hampshire LLCs Are Taxed By Default
Your New Hampshire LLC doesn’t pay taxes itself. Instead, profits flow through to you and your members, who report them on personal tax returns. This is called pass-through taxation.
Here’s how it works:
- Your LLC earns income from business activities
- The LLC itself files no tax return (unless you elect otherwise)
- Profits “pass through” to members based on ownership percentage
- Each member reports their share on their personal tax return
- Members pay tax at their individual income tax rates
What this means for you: Unlike corporations, your business profits are only taxed once, which typically saves money.
Time-Saving Tip: If you’re uncertain about your LLC’s tax classification, a tax professional can review your LLC’s tax setup in 30 minutes and help you choose the most tax-efficient option.
Tax Classification Options
While pass-through taxation is the default, your New Hampshire LLC can choose alternative tax treatments:
Default LLC Tax Status:
- Single-member LLC: Taxed as a sole proprietorship
- Multi-member LLC: Taxed as a partnership
Optional Tax Classifications:
- S Corporation: Can reduce self-employment taxes by paying “reasonable salaries”
- C Corporation: LLC pays corporate tax on profits, members pay personal tax on distributions (creates double taxation)
Not sure which tax classification is right for your business? Schedule a free consultation with 1-800Accountant.
Federal Tax Obligations
Income Tax
As a New Hampshire LLC owner, you’ll report your share of business profits on your personal tax return using:
- Form 1040 + Schedule C (single-member LLCs)
- Form 1040 + Schedule E + Schedule K-1 (multi-member LLCs)
Federal income tax rates range from 10% to 37% based on your tax bracket (actual brackets will depend on inflation adjustments and any tax law changes).
Simply Put: Whatever money your business makes (after expenses) gets added to your personal tax return, just like income from a job.
Self-Employment Tax
LLC members actively involved in the business must pay self-employment tax of 15.3% (covering Social Security and Medicare) on their share of LLC profits.
Key points:
- Applies to net earnings of $400 or more
- Calculated on Schedule SE
- You can deduct 50% of the self-employment tax as an “above-the-line” deduction, which lowers your adjusted gross income
What happens if I miss this payment? The IRS charges penalties of 0.5% per month plus interest. However, first-time mistakes can often qualify for penalty abatement if you have a clean compliance history.
Employment Taxes
If your LLC has employees, you must:
- Withhold federal income tax
- Pay and withhold FICA taxes (7.65% each for employer and employee)
- Pay federal unemployment tax (FUTA)
- File quarterly employment tax returns (Form 941)
- Provide W-2 forms annually
Estimated completion time: 2-3 hours per quarter (significantly less with payroll software or professional help)
Estimated Tax Payments
Because no tax is withheld from your LLC profits, you’ll likely need to make quarterly estimated tax payments using Form 1040-ES. These payments cover both income and self-employment taxes on your share of the business income. Missing deadlines or underpaying can lead to IRS penalties, even if you pay in full later.
Working with an accountant can help ensure accurate calculations, on-time payments, and a smarter overall tax strategy.
Key deadlines:
- April 15
- June 16
- September 15
- January 15
Pro Tip: Set calendar reminders 15 days before each deadline. This gives you time to prepare without the last-minute rush that leads to mistakes.
New Hampshire State Taxes
New Hampshire Business Profits Tax
New Hampshire imposes a flat 7.5% Business Profits Tax on your LLC’s net business income if your gross receipts are above a certain threshold. This threshold is $103,000 for tax year 2024 (and $109,000 for tax year 2025).
Filing requirements:
- Due April 15, 2025
- Use New Hampshire Form BT-Summary to report your total BPT
- File with New Hampshire Form NH-1040
Bottom Line: For every $1,000 in net business income, you can expect to pay $75 in Business Profits Tax (assuming you are over the gross receipts threshold).
New Hampshire Business Enterprise Tax
In addition to the Business Profits Tax, New Hampshire imposes a 0.55% Business Enterprise Tax on your LLC’s enterprise value tax base (all compensation, interest, and dividends paid or accrued during the year).
Filing requirements:
- Due April 15, 2025
- File with New Hampshire Form BET
- Only applies if your gross receipts exceed $277,000 (or $298,000 for 2025)
Note: Keep in mind that any BET tax your LLC pays can be used as a credit against your Business Profits Tax liability.
New Hampshire Interest and Dividends Tax
If your LLC receives significant interest or dividend income, this may trigger the state’s Interest and Dividends Tax.
- Applies only if total interest and dividend income exceeds $2,400
- Rate is 3% on taxable interest and dividend income
- File with New Hampshire Form DP-10
Note: This tax was repealed for tax years beginning on or after January 1, 2025.
New Hampshire Unemployment Insurance (UI) Tax
If you have employees in New Hampshire, you will be responsible for Unemployment Insurance Tax.
- Register through New Hampshire Employment Security
- Rate is 2.7% for new employers (0.1%–7.5% afterwards, based on experience rating)
- Due quarterly
New Hampshire Annual Report

- Due April 1, 2025
- $100 filing fee
- Filed online through New Hampshire QuickStart
- Failure to file may result in administrative dissolution

Tax Strategies for New Hampshire LLCs
S Corporation Election Benefits
Converting your LLC to an S Corporation for tax purposes can save on self-employment taxes:
- File Form 2553 with the IRS
- Pay yourself a “reasonable salary” subject to employment taxes
- Take remaining profits as distributions exempt from self-employment tax
Example: An LLC making $100,000 in profit pays 15.3% self-employment tax on the entire amount. As an S Corp, if $60,000 is a reasonable salary and $40,000 is taken as distributions, only the $60,000 is subject to employment taxes.
Potential Savings: In this example, you’d save about $6,120 in self-employment taxes.

Common deductions New Hampshire LLC owners often overlook:
- Home office deduction
- Business mileage (70¢ per mile for 2025)

However, an LLC can also be taxed as a corporation if it meets certain tax requirements.
