Should I Start My Business as a Partnership?

By Bill Stilwell · Last reviewed October 16, 2026

The short answer

A partnership is a business owned by two or more people who share its profits, without forming a corporation or limited liability company (LLC). In a general partnership, each partner can be personally responsible for the business’s debts, while limited partnerships and limited liability partnerships change who carries that risk. Whichever type you choose, put a written partnership agreement in place before you start, because most partnership problems come from things nobody wrote down.

What this means

The outline asks you to review ownership, authority, liability, taxes, contributions, and exit rules.

Types. The U.S. Small Business Administration (SBA) describes three:

General partnership: two or more owners, and partners have unlimited personal liability.
Limited partnership (LP): at least one general partner with unlimited liability, plus limited partners who have liability protection but usually less control.
Limited liability partnership (LLP): every owner has limited liability, so partners aren’t responsible for the partnership’s debts or other partners’ actions. Some states limit LLPs to certain professions. California, for example, limits them to fields like law, accounting, architecture, engineering, and land surveying. Check your state.

Ownership and contributions. Who owns what share, and what each person puts in: money, equipment, clients, or work (see 6.2.1 Ownership Percentages and Capital Contributions).

Authority. Who can sign contracts, spend money, hire, and borrow. In a general partnership, a partner can often bind the business, which means your partner’s signature can commit you.

Taxes. The Internal Revenue Service (IRS) says a partnership generally doesn’t pay income tax itself. It files Form 1065, and each partner’s share of profit or loss passes to them on a Schedule K-1 for their own return. Partners in a general partnership generally pay self-employment tax on their share. A partnership needs an Employer Identification Number (EIN).

Exit rules. What happens if a partner quits, dies, divorces, or wants to sell (see 6.2.6 Buy-Sell Provisions).

Example: two friends start a pressure washing business (made up for this page). One brings the truck and equipment. The other brings sales skills and a customer list. Their agreement says the truck stays with the business if either leaves, the customer list belongs to the business, and either partner can buy the other out at a set formula.

Why it matters

You can be liable for your partner’s decisions. In a general partnership, a debt your partner signs for can become your debt.
A partnership can form by accident. The IRS treats two or more people running a business and dividing profits as a partnership for tax purposes, even with nothing filed. Many people are partners without realizing it.
No agreement means state default rules. If you don’t write your own rules, your state’s partnership law fills the gaps, and those rules may not match what you intended.
Splits get expensive. Without exit rules, a breakup can mean a lawsuit over equipment, clients, the name, and online accounts.

Who this applies to

Any business with two or more owners that isn’t formed as an LLC or corporation. If you and someone else share profits from a business, read this page even if you never filed anything. Many co-owners form an LLC instead (see 8.6.3 Limited Liability Company). They still need the same kind of written agreement, called an operating agreement.

How to do it

Talk through the hard questions first. Ownership split, who does what, how much each person invests, how you’ll pay yourselves, and what happens if someone leaves.
Compare structures with a pro. Ask an attorney and a certified public accountant (CPA) whether a general partnership, LP, LLP, or LLC fits your risk and taxes.
Check your state’s rules. SBA says LPs and LLPs generally file a certificate with the state, though not all states require it or use the same name. Check your Secretary of State’s website.
Write the partnership agreement. Cover ownership, contributions, authority, profit sharing, decisions, deadlocks, intellectual property, and exits (see 6.2.3 Decision-Making Authority and Voting, 6.2.5 Deadlock Procedures, and 6.2.7 Intellectual-Property Ownership).
Have each partner get their own advice if interests differ a lot. One lawyer for both sides can be a conflict.
File any required state forms, plus a doing business as (DBA) filing if you use a brand name (see 8.1.2 DBA or Trade Name).
Get an EIN for the partnership (see 10.1.1 Employer Identification Number).
Open a business bank account in the partnership’s name, with clear signing rules.
Set up account ownership. Put the Google Business Profile, domain, website, and social accounts under business-controlled logins with at least two admins (see 8.4.6 Two Business-Controlled Administrators and 14.3.8 Profile Ownership).
Record ownership in an ownership ledger and update it with every change (see 8.7.4 Ownership Ledger).

What proof to keep

The signed partnership agreement and every amendment
State filings, such as an LP or LLP certificate, if any
DBA filing, if you use a brand name
EIN confirmation letter
Records of each partner’s contributions
Ownership ledger
Each year’s Form 1065 and Schedule K-1s

Common mistakes

Starting on a handshake. Friends and family partnerships often fall apart over expectations nobody wrote down.
Splitting 50/50 with no deadlock rule. When you disagree, nothing moves. Write a tiebreaker.
Not saying who owns the customer list, name, and accounts. These are often the most valuable assets.
Letting one partner own the Google Business Profile personally. If they leave, the business can lose control of its listing and reviews.
Assuming an LLP is available. Some states, like California, limit LLPs to certain licensed professions.
Forgetting about taxes on money you didn’t take out. Partners can owe tax on their share of profit even if it stayed in the business.

When to get help from a pro

An attorney should draft or review the partnership agreement. A CPA should explain the taxes. Ask the attorney:

In our state, can one partner bind the business without the other’s approval?
What happens to the business, its name, and its accounts if one of us leaves or dies?

Ask the CPA:

How will each of us be taxed on our share, including self-employment tax?
Would an LLC or S corporation election change our taxes?

Bill’s note

[Bill: add a short story or opinion. For example, a client partnership that split and fought over the Google Business Profile, or how you’d set up account ownership with a partner.]

If you’d rather have this done for you, SiteSmarty sets up Google Business Profiles with business-controlled ownership and backup managers.

Questions people ask

What’s the difference between a general partnership and an LLP? In a general partnership, partners can be personally liable for business debts. SBA says in an LLP, partners aren’t responsible for the partnership’s debts or other partners’ actions. Some states limit who can form an LLP.

Do we need a written partnership agreement? It isn’t always required, but SBA recommends one. Without it, your state’s default rules apply.

How is a partnership taxed? The IRS says the partnership files Form 1065 but generally doesn’t pay income tax. Each partner reports their share from Schedule K-1.

Am I liable for my partner’s mistakes? In a general partnership, you can be. Limited partners and LLP partners have more protection.

What happens if a partner wants out? Whatever your agreement says. With no agreement, state law decides, which can be messy.

Audit check

Question: Do the co-owners have a signed partnership agreement covering ownership, authority, contributions, taxes, and exits, with business accounts held by the business?
Pass looks like: A signed, current agreement, required state filings, an EIN, a business bank account, an ownership ledger, and the Google Business Profile and domain under business-controlled logins.
Fail looks like: No written agreement. One partner personally owns the profile, domain, or bank account. No exit or deadlock rules.
Evidence to collect: Signed agreement, state filings, EIN letter, ownership ledger, and a screenshot of the profile’s owners and managers list.

Where this fits
