A 70/30 partnership agreement is the written contract between two business owners who hold unequal stakes, with one partner owning 70% and the other 30%, and it controls how money, decisions, and exits are handled between them. Getting it in writing matters because most states have adopted a version of the Revised Uniform Partnership Act, and those default rules assume equal profit sharing, equal management authority, and equal contributions. Nothing about a 70/30 arrangement is equal. Without a signed document stating the split, a court will likely fall back on the equal-share defaults and ignore whatever the partners discussed verbally.
The stakes are higher than many first-time partners realize. In a general partnership, both owners carry unlimited personal liability for the business’s debts, and that liability is joint and several. A creditor doesn’t have to split a claim proportionally; if the 30% partner has deeper pockets, the creditor can pursue that partner for the full amount. Each partner is also a legal agent of the other, so a contract one partner signs with a supplier binds both, even without the other’s approval. A well-drafted agreement sets dollar thresholds for binding commitments and requires joint consent above that limit. Partners who want stronger liability protection should look at a limited liability partnership or an LLC instead.
Capital Contributions That Justify the Split
The agreement needs to document exactly what each partner contributes to earn the 70/30 ownership. In a straightforward setup, the 70% partner contributes $70,000 in cash and the 30% partner contributes $30,000 in cash or equipment. When property or equipment is involved, get a formal appraisal. The IRS tracks each partner’s capital account using adjusted tax basis rather than market value, so accurate numbers at the start prevent problems at tax time.
Include a schedule listing each contribution, its value, and the deadline for transferring it to the partnership’s bank account or title. A missed deadline should trigger a defined consequence: a reduction in ownership percentage, an interest charge, or the right for the other partner to dissolve the partnership. Leaving this vague invites the exact dispute the agreement exists to prevent.
When a partner contributes a trademark, patent, proprietary software, or other intellectual property, the agreement must distinguish between an outright assignment, which transfers ownership to the partnership, and a license, which lets the partnership use the IP while the partner keeps it. Without an explicit assignment clause, the contributing partner likely still owns the IP personally, which becomes a problem if they leave. The agreement should also assign IP created during the partnership to the business rather than to the partner who developed it.
Beyond contributions, the opening section of the agreement should state the business’s legal name, principal address, and the full legal names and addresses of both partners. The name must be distinguishable from other entities registered with the state. Most Secretary of State offices offer a free online name search, though those searches typically cover only state filings and do not check federal trademarks. Also state the partnership’s purpose (broad or narrow), its start date, its expected duration, and the accounting method, usually cash or accrual.
How Profits and Losses Flow Under the Split
Federal tax law says a partner’s share of income, gain, loss, and deductions is determined by the partnership agreement.1Office of the Law Revision Counsel. 26 USC 704 – Partners Distributive Share In a 70/30 setup, the majority partner receives 70 cents of every dollar distributed and bears 70% of any losses. The minority partner receives and bears the remaining 30%. This proportional allocation is the simplest approach and generally avoids the complex “substantial economic effect” rules the IRS applies when partnerships allocate profits in ratios that don’t match ownership.
If the business posts a $10,000 loss in a given year, the 70% partner reports $7,000 of that loss on their personal return and the 30% partner reports $3,000. Specify the fiscal year (typically ending December 31 for calendar-year partnerships) and the accounting method in the agreement, since both affect when income and expenses get recognized.
Distribution timing matters too. The agreement should say whether distributions happen monthly, quarterly, or annually, and it should set a minimum cash reserve the business must maintain before any distribution occurs. Partners who drain the account every quarter leave the business unable to cover an unexpected expense or a slow month, and that puts both partners’ personal assets at risk. A common safeguard: require unanimous consent for any distribution that would drop the operating account below a stated threshold.
Management, Voting, and the Minority Partner’s Protection
In most 70/30 partnerships, voting power follows ownership percentages, giving the majority partner effective control over routine decisions. The agreement should define what counts as routine and what requires both partners to agree. A workable approach: day-to-day spending and operational choices go to whoever holds the managing partner role, with a dollar cap, and anything above that cap requires both partners’ written consent.
Decisions that commonly require unanimous approval regardless of ownership:
- Selling the business or substantially all of its assets
- Admitting a new partner or changing ownership percentages
- Taking on debt above a specified amount
- Entering a lease beyond a stated term or annual cost
- Filing for bankruptcy or voluntarily dissolving the partnership
The agreement should also name a managing partner and describe that role’s scope: authority to sign checks, hire and fire employees, negotiate vendor contracts, and handle regulatory filings. If both partners are active in the business, define their respective lanes so neither steps on the other’s work.
Fiduciary duties exist by law and matter especially to the minority partner. Under the Revised Uniform Partnership Act, every partner owes a duty of loyalty (no competing with the partnership, no self-dealing, no pocketing business opportunities for yourself) and a duty of care (no grossly negligent or reckless conduct, no intentional wrongdoing). These duties apply even if the agreement says nothing about them, though the agreement can clarify their scope within state law limits. Because the majority partner’s voting control makes it possible to steer the business in ways that favor one side, a well-drafted agreement for the minority partner requires full financial transparency, regular accounting reports, and equal access to the books.
Taxes Each Partner Owes Under a 70/30 Split
A partnership does not pay income tax itself. It files an informational return on Form 1065 and sends each partner a Schedule K-1 showing their share of income, deductions, and credits.2Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income Each partner then reports those items on their personal return. The character of the income passes through as well, so capital gains earned by the partnership stay capital gains on your individual return.3Office of the Law Revision Counsel. 26 USC 702 – Income and Credits of Partner
Calendar-year partnerships must file Form 1065 by March 15 each year, with the deadline shifting to the next business day when it falls on a weekend. For the 2025 tax year, that means March 16, 2026. An automatic six-month extension is available by filing Form 7004, pushing the deadline to September 15. The extension gives more time to file, but it does not extend the time to pay any tax the partners owe individually.
Partnership income isn’t subject to payroll withholding, so each partner owes self-employment tax on their distributive share. The combined rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.4Office of the Law Revision Counsel. 26 USC 1401 – Rate of Tax The Social Security portion applies only to the first $184,500 of net self-employment income in 2026.5Social Security Administration. Contribution and Benefit Base The Medicare portion has no cap. An additional 0.9% Medicare surtax applies above $200,000 for single filers or $250,000 for married couples filing jointly.6Internal Revenue Service. Questions and Answers for the Additional Medicare Tax
The 70/30 split creates meaningful tax planning differences. If the partnership earns $200,000, the majority partner’s $140,000 share triggers roughly $19,800 in self-employment tax alone, before income tax. The minority partner’s $60,000 share generates about $8,500. First-time partners who are used to FICA being split with an employer often find these amounts jarring.
Because no employer withholds taxes from distributions, each partner must make quarterly estimated tax payments if they expect to owe $1,000 or more for the year.7Internal Revenue Service. Estimated Taxes For tax year 2026, those payments are due April 15, June 15, and September 15 of 2026, plus January 15, 2027.8Internal Revenue Service. 2026 Form 1040-ES Missing a payment triggers an underpayment penalty. The IRS holds each partner individually responsible regardless of what the partnership’s bank account looks like.
The partnership also needs an Employer Identification Number from the IRS before opening a bank account, hiring employees, or filing taxes. The IRS issues EINs at no charge, so be wary of third-party sites that charge for the service.9Internal Revenue Service.

Resolving Disputes Before They Break the Business
Every partnership hits a disagreement eventually. The agreement should prescribe how to handle it before emotions are running high. The most effective approach is a multi-tiered escalation: a defined period of good-faith negotiation (typically 30 days), then mediation with a neutral third party if negotiation fails, and binding arbitration only as a last resort. Each step needs a deadline to prevent one partner from stalling.
An arbitration clause should specify the arbitration organization, the number of arbitrators, the location of proceedings, and whether the decision is binding. Mandatory language (“shall” rather than “may”) makes the clause enforceable. Courts in most jurisdictions will refuse to hear a lawsuit when the agreement requires arbitration first and the complaining partner skipped that step. Arbitration tends to be faster and cheaper than litigation and keeps the dispute private.
Buy-Sell Provisions: Planning the Exit in Advance
The agreement should answer a question both partners hope they won’t need: what happens when one of them wants out? A buy-sell provision sets the rules in advance for voluntary withdrawal, involuntary removal, retirement, death, and disability.
Right of First Refusal
A right of first refusal prevents a partner from selling their interest to an outside party without first offering it to the remaining partner on the same terms. The clause should specify a response window, commonly 30 to 60 days, during which the remaining partner must accept or decline. If they decline, the departing partner can sell to the third party at the same price and terms.
Valuation Methods
Agreeing on what the interest is worth is the hardest part of any buyout. Three common approaches:
- Fixed value: the partners agree on a specific dollar amount, listed as an exhibit and updated annually. Simple, but it goes stale fast.
- Formula: a defined calculation based on earnings, book value, or a multiple of revenue. Predictable, but formulas can produce results that feel unfair in unusual years.
- Independent appraisal: a business appraiser determines fair market value after a triggering event. More accurate, more expensive, slower.
Whichever method you pick, specify who pays for the appraisal, whether more than one appraisal is permitted, and the effective date for valuation. Naming a single agreed-upon appraiser in advance eliminates the common fight over who gets to pick the expert.
Death or Disability
If a partner dies, their interest passes to their estate unless the agreement says otherwise. That can leave the surviving partner in business with the deceased partner’s spouse or heirs, which is rarely what anyone wants. A well-drafted agreement gives the surviving partner the right (or obligation) to buy the deceased partner’s interest at the agreed-upon valuation, often funded by a life insurance policy on each partner. Define “disability” clearly, often as the inability to perform partnership duties for 180 consecutive days, and provide a similar buyout mechanism.
Payment terms matter too. Requiring full cash payment within 30 days can bankrupt the business. Many agreements allow installment payments over two to four years, with interest at the applicable federal rate, so the business can absorb the cost without liquidating assets.
Dissolution and Winding Up
Dissolution is the formal process of ending the partnership. The agreement should list the events that trigger it: expiration of a fixed term, a vote of both partners, a court order, or an event that makes the business illegal to operate. Without these provisions, state default rules control, and those rules vary widely.
Once dissolution is triggered, winding up typically follows this order:
- Finish existing obligations: complete open contracts, collect receivables, and sell remaining inventory or assets.
- Pay creditors: all business debts, including loans and vendor balances, get paid first.
- Return capital contributions: each partner receives their capital account balance.
- Distribute remaining assets: whatever is left gets split 70/30 along ownership lines.
If the partnership’s debts exceed its assets, each partner is personally liable for the shortfall in proportion to their ownership share, unless the agreement specifies otherwise. Designate who handles winding up, set a timeline, and require a final accounting.
Signing and Keeping the Agreement Current
A partnership agreement becomes binding when both partners sign. Notarization is not legally required in most states, but having a notary verify identity adds protection if anyone later claims they didn’t sign voluntarily. If the partnership will buy or sell real estate, some states require notarized documents for property transactions, so notarizing from the start avoids a second round of signatures later. Electronic signatures carry the same legal weight as handwritten ones for contracts affecting interstate commerce under the federal E-Sign Act.11Federal Deposit Insurance Corporation. Electronic Signatures in Global and National Commerce Act
Each partner should keep an original or a certified electronic copy in a secure location. You’ll need the agreement when opening a business bank account, applying for credit, proving authority to a landlord or vendor, and filing taxes. Consider filing a Statement of Partnership Authority with the Secretary of State. This public filing identifies who has the power to act on the partnership’s behalf, which title companies and financial institutions often require before completing transactions. Filing fees vary by state, generally between $25 and $70.
Review the agreement annually, especially the valuation exhibit if you’re using a fixed-value buyout, and amend it in writing whenever the partners’ roles, contributions, or business circumstances change. An outdated agreement is nearly as dangerous as no agreement at all.
