When Partnership Makes Sense (and When LLC Is Better)
General Partnership May Be Appropriate
- Temporary project with defined completion date (under 12 months)
- Low-risk consulting with no physical assets or employees
- Partners prefer maximum simplicity and have no liability exposure
- Professional firms in states that require LLP for licensed practitioners
LLC Is Better (Most Businesses)
- Any business with physical assets (equipment, real estate, inventory)
- Any business with employees or contractors
- Any business with customer-facing operations
- Any business with significant revenue or debt
- Any business seeking bank financing
- Any business in a regulated or high-liability industry
How to Convert a Partnership to an LLC (Step by Step)
Draft the LLC Operating Agreement
The operating agreement replaces your partnership agreement. It should include the same key provisions (capital contributions, profit splits, management authority, exit terms) plus LLC-specific provisions (member voting, manager authority if manager-managed).
File Articles of Organization
File with the Secretary of State in your formation state. Most states have a statutory conversion form (Form LLC-1A or similar) that converts the partnership directly to LLC without requiring dissolution. Cost: $50 to $500 plus any expedite fees.
Obtain a New EIN
Apply for a new Employer Identification Number at IRS.gov (free, takes minutes). The partnership EIN does not transfer to the LLC. You will need the new EIN for bank accounts, tax filings, and vendor forms.
Update Bank Accounts and Contracts
Notify your bank and open new accounts under the LLC name (or update existing accounts with documentation). Update contracts, leases, insurance policies, licenses, and vendor agreements. Send a brief conversion notice to key customers.
File Final Partnership Tax Return
File a final Form 1065 for the partnership's last tax year, marked 'final return.' Issue final K-1s to all former partners. Begin filing as an LLC (default: same as partnership; or elect S-corp taxation for potential SE tax savings).
FAQ
Should I form a partnership or LLC?
For the vast majority of new businesses, an LLC is the better choice. An LLC provides personal liability protection, similar pass-through tax treatment, and more credibility with banks. The only situations where a general partnership makes sense: temporary projects with defined end dates, very low-risk consulting with no physical assets, or professional firms requiring LLP structure.
What is the difference between a partnership and an LLC?
Key differences: (1) Liability - partners in a general partnership have unlimited personal liability; LLC members are protected from business debts. (2) Formation - partnerships require no state filing; LLCs file Articles of Organization ($50-$500). (3) Tax flexibility - LLCs can elect S-corp taxation to save self-employment taxes. (4) Credibility - LLCs appear more established to banks and vendors.
How do you convert a partnership to an LLC?
Converting involves: (1) Draft an LLC operating agreement; (2) File Articles of Organization with the Secretary of State (statutory conversion forms available in most states, $50-$500); (3) Obtain a new EIN from the IRS; (4) Update bank accounts, licenses, and contracts; (5) File a final partnership tax return. The IRS treats most conversions as a continuation, avoiding immediate tax triggers.
