How to Form a Business Partnership
If you’ve found a business partner and you’re ready to make it official, you’re in the right place. This guide covers everything you need to know about forming a business partnership — from choosing the right type to filing paperwork to avoiding expensive mistakes.
By the time you finish reading this, you’ll know exactly which steps to take and what forms to file. More importantly, you’ll understand why each step matters and how to protect yourself along the way.
This takes about 8 minutes to read and will save you hours of confusion (and potentially thousands in legal fees).
What You Need to Know First
A business partnership is simply two or more people who agree to run a business together and share profits and losses. Think of it as making your handshake agreement official and legal.
Here’s what most people don’t realize: the moment you start doing business with someone else, you’re already in a partnership legally speaking. The question is whether you want to control the terms or let state law decide for you.
Who This Works Best For
Partnerships make sense when you have complementary skills and want to share both the work and the financial responsibility. For example:
- A web developer and marketing expert starting a digital agency
- Two contractors who want to bid on larger projects together
- A chef and restaurant manager opening a restaurant
- Freelancers who regularly collaborate and want to formalize their arrangement
Common Myths About Partnerships
Myth: “We don’t need paperwork — we trust each other.”
Reality: Partnership agreements protect good relationships. They prevent confusion and arguments before they happen.
Myth: “Partnerships are cheaper than LLCs.”
Reality: While forming a general partnership costs less upfront, you lose liability protection. Most business advisors recommend an LLC with multiple members instead.
Myth: “All partnerships are 50/50.”
Reality: You can split ownership, profits, and decision-making any way you want. Put it in writing.
When This Doesn’t Apply
Skip partnerships if you want to be the sole decision-maker or if you’re looking for liability protection. In those cases, form an LLC or corporation instead. Also skip this if your potential partner has serious financial problems — you’ll be personally liable for business debts in a general partnership.
How to Form a Partnership — Step by Step
Before You Start
Have these conversations with your partner first:
- Who contributes what (money, time, skills, equipment)
- How you’ll split profits and losses
- Who makes which decisions
- What happens if someone wants out
These decisions will go into your partnership agreement.
Step 1: Choose Your Partnership Type (30 minutes)
You have three options:
General Partnership (GP): All partners share management duties and personal liability for business debts. Simplest to form but riskiest for your personal assets.
Limited Partnership (LP): Has general partners (who manage and have liability) and limited partners (who invest money but don’t manage). Requires state filing.
Limited Liability Partnership (LLP): Partners aren’t personally liable for other partners’ mistakes. Only available for certain professions like lawyers and accountants in most states.
Most small businesses choose general partnerships because they’re simple, or they skip partnerships entirely and form an LLC instead.
Step 2: Choose Your Business Name (15 minutes)
Your partnership can operate under the partners’ names (“Smith and Johnson Consulting”) or you can choose a different name.
If you pick a different name, you’ll need to file a “Doing Business As” (DBA) form with your county or state. This costs $25-$100 in most places and takes 1-2 weeks to process.
Check name availability by searching your state’s business database and doing a Google search.
Step 3: Get Required Licenses and Permits (1-4 weeks)
This depends entirely on your business type and location. A consulting partnership might need nothing more than a business license. A restaurant partnership needs food service permits, liquor licenses, and health department approvals.
Check with your city clerk’s office and your state’s business website for requirements.
Step 4: Get an EIN (Same Day)
An Employer Identification Number (EIN) is your business tax ID. You need one to open business bank accounts and file tax returns.
Apply directly with the IRS online at irs.gov. It’s free and takes about 15 minutes. You’ll get your EIN immediately.
Avoid third-party services that charge for this — they’re just filing the same free form.
Step 5: Write Your Partnership Agreement (1-2 weeks)
This is the most important step. Your partnership agreement should cover:
- Each partner’s contribution (money, property, time)
- Profit and loss sharing percentages
- Management responsibilities and decision-making authority
- How to add or remove partners
- What happens if a partner dies or becomes disabled
- How to dissolve the partnership
You can find partnership agreement templates online, but consider hiring an attorney for this. A good partnership agreement costs $1,000-$3,000 but prevents expensive disputes later.
Step 6: Open a Business Bank Account (1 week)
Keep business and personal finances separate from day one. You’ll need your EIN, partnership agreement, and identification to open an account.
Most banks require all partners to sign the account opening documents.
Step 7: Set Up Accounting and Tax Planning (1-2 weeks)
Partnerships are “pass-through” entities — the business doesn’t pay taxes, but profits and losses pass through to partners’ personal tax returns.
The partnership must file Form 1065 annually and give each partner a K-1 form showing their share of income and losses.
Set up bookkeeping software (QuickBooks, FreshBooks, or Wave) from the start. Consider hiring a CPA who understands partnership taxation.
What It Costs
State Filing Fees
General partnerships don’t require state filing in most states, so there’s no fee. Limited partnerships and LLPs typically cost $100-$300 to file, depending on your state.
DBA Registration
If you’re using a business name other than your legal names: $25-$100
EIN application
Free if you apply directly with the IRS. Third-party services charge $50-$200 for the same free form.
Partnership Agreement
- DIY with online templates: $50-$200
- Attorney-prepared: $1,000-$3,000
- Online legal services: $300-$800
Other Startup Costs
- Business licenses: $50-$500 depending on your business
- Business bank account: $0-$25 monthly maintenance fee
- Accounting software: $15-$50 per month
- Business insurance: $400-$1,500 annually
Total Bottom Line
Most partnerships spend $500-$2,000 to get properly set up, not counting industry-specific licenses or initial business insurance. The partnership agreement is usually the biggest expense, but it’s worth every dollar.
Mistakes That Cost People Money
1. Operating Without a Written Agreement
The mistake: “We’ll figure it out as we go” or relying on a handshake deal.
Why it happens: Partners focus on the exciting business stuff and skip the boring legal stuff.
The cost: Partnership disputes are expensive and nasty. Without a written agreement, state law decides everything — and state law probably doesn’t match what you had in mind.
How to prevent it: Write a partnership agreement before you start operating, not after problems arise.
2. Not Planning for Partner Departure
The mistake: Failing to address what happens when someone wants out or dies.
Why it happens: Nobody wants to think about worst-case scenarios when starting a business.
The cost: The business might have to shut down, or remaining partners might have to work with the deceased partner’s spouse or heirs.
How to prevent it: Include buy-sell provisions in your partnership agreement. Consider life insurance on each partner to fund buyouts.
3. Mixing Personal and Business Money
The mistake: Using personal accounts for business expenses or vice versa.
Why it happens: It’s easier than opening separate accounts, especially early on.
The cost: Tax headaches, lost deductions, and potential legal problems if you’re ever sued.
How to prevent it: Open a business bank account before you start operating. Use it for everything business-related.
4. Ignoring Self-Employment Taxes
The mistake: Not setting aside money for quarterly tax payments.
Why it happens: Partners don’t realize they’re considered self-employed and owe both income tax and self-employment tax (Social Security and Medicare).
The cost: Penalties and interest on late payments, plus a huge tax bill in April.
How to prevent it: Work with a CPA to calculate quarterly payments. Set aside 25-30% of profits for taxes.
5. Choosing Partnership Over LLC by Default
The mistake: Forming a general partnership because it’s simple, without considering alternatives.
Why it happens: People hear “partnership” and assume it’s the right choice for partners.
The cost: Personal liability for business debts and other partners’ mistakes.
How to prevent it: Consider an LLC with multiple members instead. You get liability protection with similar tax treatment and operational flexibility.
6. Not Getting Proper Insurance
The mistake: Skipping general liability insurance or professional liability coverage.
Why it happens: Trying to save money in the early days.
The cost: Personal assets at risk if the business gets sued.
How to prevent it: Get quotes for general liability insurance before you start operating. It’s cheaper than you think, and your partnership agreement should require it.
For International Founders
Good news: non-U.S. citizens can absolutely form partnerships in the United States. There’s no visa or residency requirement.
However, most international founders should consider an LLC instead of a partnership. LLCs provide liability protection and are easier to manage from abroad.
Popular States for International Partnerships
Wyoming and Delaware top the list for international founders. Wyoming offers privacy protections and no state income tax. Delaware has business-friendly courts and is widely recognized by banks and investors.
The Registered Agent Requirement
You’ll need a registered agent with a physical U.S. address in your formation state. This can’t be a P.O. box. We provide registered agent services in all 50 states, which solves this requirement completely.
Getting an EIN as a Non-Resident
The process is slightly different for international founders. You might need to file Form SS-4 by fax instead of applying online, which takes 4-8 weeks instead of getting immediate approval.
Banking Challenges
Opening a U.S. business bank account is the biggest hurdle for international partnerships. Traditional banks often require a U.S. address and Social Security number.
Consider online business banks like Mercury, Relay, or Wise Business, which are more international-friendly. Some require an EIN and business formation documents but don’t require U.S. residency.
Tax Obligations
Partnerships with foreign partners have additional filing requirements. You’ll likely need to file Form 5472 annually, and penalties for non-filing start at $25,000.
This is complex enough that you should work with a CPA who specializes in international tax from the beginning. Don’t try to figure this out on your own.
Frequently Asked Questions
Do I need to register my general partnership with the state?
Usually not. General partnerships exist automatically when two or more people do business together. You only need state filing for limited partnerships or LLPs in most states.
Can my partnership have different profit splits than ownership splits?
Yes. You might own 50/50 but agree to split profits 60/40 based on who brings in more clients. Put these arrangements in your partnership agreement.
What’s the difference between a partnership and an LLC with multiple members?
The main difference is liability protection. LLC members aren’t personally liable for business debts. Partners in a general partnership are. Tax treatment is similar for both.
Can I add partners later?
Yes, but it requires amending your partnership agreement and potentially updating your EIN information with the IRS. Plan for this possibility when you write your original agreement.
Do partnerships need operating agreements?
Partnerships have “partnership agreements” instead of operating agreements (that’s an LLC term). But yes, you absolutely need a written partnership agreement.
What happens if my partner quits suddenly?
Whatever your partnership agreement says happens. Without an agreement, state law takes over, which might force you to dissolve the entire business. This is why buy-sell clauses are crucial.
Can a partnership own property?
Yes, partnerships can own real estate, equipment, and other business assets. The partnership owns the property, not the individual partners.
How do I dissolve a partnership?
Follow the dissolution process in your partnership agreement. If you don’t have an agreement, you’ll need to follow your state’s default process, which usually involves settling debts, distributing assets, and filing final tax returns.
