New Hampshire's lack of state income tax makes it an excellent state for dental practice LLCs. You'll benefit from self-employment tax savings through S-Corp election, liability separation between practice operations and personal assets, and streamlined insurance credentialing processes that most dental insurance networks require.
Key Benefits of an LLC for New Hampshire
Self-Employment Tax Savings
Elect S-Corp status to save thousands annually on self-employment taxes by paying yourself a reasonable salary and taking additional profits as distributions, which aren't subject to Medicare and Social Security taxes.
Simplified Practice Acquisition Structure
LLCs provide a clean ownership structure for acquiring existing dental practices or bringing in associate dentists as members, making transitions and buy-ins much more straightforward than sole proprietorships.
Enhanced Insurance Credentialing
Most dental insurance networks and PPO plans require business entity status for credentialing. An LLC streamlines this process and maintains your provider numbers during ownership changes.
Liability Separation for Associates
Protect your personal assets from malpractice claims against associate dentists by clearly separating business operations from your personal finances through the LLC structure.
Equipment and Supply Tax Benefits
Maximize deductions for dental equipment purchases, lab fees, continuing education, and practice supplies while maintaining clear business expense documentation required for dental practice audits.
How to Form Your LLC
- 1
Choose Your Dental Practice Name
Select a name ending in 'LLC' that reflects your dental practice. Avoid using 'Dr.' in the LLC name as it may complicate insurance credentialing. Check name availability on the New Hampshire Secretary of State website and ensure it doesn't conflict with existing dental practices in your area.
- 2
Appoint a Registered Agent
Your registered agent receives legal documents and state correspondence. Many dentists use a professional service to maintain privacy and ensure documents aren't missed during practice hours or vacations. The agent must have a New Hampshire address.
- 3
File Articles of Organization
Submit your Articles of Organization to the New Hampshire Secretary of State with the $100 filing fee. Include your practice address and specify if you'll have multiple dental locations under the same LLC. Processing takes 5 business days.
- 4
Create an Operating Agreement
Draft an operating agreement that addresses associate dentist arrangements, profit-sharing for hygienists or staff, equipment ownership, and succession planning. This is crucial for multi-dentist practices and protects your practice structure.
- 5
Obtain Required Licenses and Insurance
Transfer your dental license to the LLC name, update malpractice insurance policies, and notify dental insurance networks of your new business structure. Update your DEA registration and any controlled substance licenses to reflect the LLC.
Tax Considerations
Self Employment Tax
Dental practice LLCs can elect S-Corp status to significantly reduce self-employment taxes. Instead of paying 15.3% SE tax on all practice profits, you'll pay yourself a reasonable salary (subject to payroll taxes) and take remaining profits as distributions, which aren't subject to Medicare and Social Security taxes.
Deductions
Maximize deductions for dental equipment, lab fees, dental supplies, malpractice insurance premiums, continuing education courses, staff wages and benefits, office rent or mortgage interest, and practice marketing expenses. LLCs provide clear business expense documentation that's essential for dental practice tax compliance.
State Taxes
New Hampshire has no state income tax, making it highly favorable for dental practice profits. However, you'll still pay the Interest and Dividends Tax if applicable, and annual LLC reporting fees of $100 are due April 1st each year.
