How Partnerships Are Taxed
Business partnerships occupy a unique position in the tax code. Unlike corporations, partnerships don't pay income tax at the entity level. Instead, income, losses, deductions, and credits "pass through" to the individual partners, who report their share on their personal tax returns.
This pass-through treatment avoids the double taxation that affects C corporations, but it creates its own complexities — from self-employment taxes to special allocations to quarterly estimated payments.
Pass-Through Taxation Basics
How It Works
The partnership files an informational return (Form 1065) with the IRS each year. This return reports the partnership's total income, deductions, and credits but doesn't result in any tax payment by the partnership itself.
Each partner receives a Schedule K-1 that reports their individual share of the partnership's income, losses, deductions, and credits. Partners then include these amounts on their personal income tax returns (Form 1040), regardless of whether the partnership actually distributed any cash to them.
The Critical Detail: Phantom Income
Partners owe tax on their allocated share of partnership income even if the partnership retained all the profits and distributed nothing. This "phantom income" situation is common in growing businesses that reinvest profits rather than distributing them.
Example: A partnership earns $200,000 and retains all of it for expansion. If you're a 50% partner, you owe taxes on $100,000 of income even though you received zero cash. Your personal tax bill on this phantom income could easily exceed $30,000.
Include a "tax distribution" provision in your partnership agreement that requires the partnership to distribute at least enough cash to each partner to cover their tax liability on allocated partnership income. This prevents partners from being stuck with tax bills they can't pay.
Self-Employment Tax
General partners pay self-employment tax (Social Security and Medicare) on their share of partnership income. For 2025, this is 15.3% on the first $168,600 of self-employment income, plus 2.9% Medicare tax on all self-employment income above that threshold. An additional 0.9% Medicare surtax applies to self-employment income over $200,000 ($250,000 for married filing jointly).
Limited partners generally don't pay self-employment tax on their share of partnership income, though guaranteed payments to limited partners are subject to it. This distinction is one reason some partners prefer limited partnership structures.
Allocation of Income and Losses
Default Allocation
Unless the partnership agreement specifies otherwise, profits and losses are allocated equally among partners — regardless of capital contributions or ownership percentages. This default rarely reflects the partners' actual intent.
Special Allocations
The partnership agreement can allocate income and losses in any proportion the partners choose, as long as the allocations have "substantial economic effect" under IRS regulations. This means:
- The allocation must actually affect partners' capital accounts — it can't be a paper-only arrangement
- Partners must bear the economic consequences — if losses are allocated to a partner, that partner's capital account must reflect the reduction
- Liquidating distributions must follow capital account balances — when the partnership dissolves, distributions go according to capital accounts, not some other formula
Why Special Allocations Matter
Special allocations give partnerships enormous flexibility. Common scenarios include:
- Allocating depreciation to the partner who contributed the property being depreciated
- Allocating early-year losses to partners with other income who can use the tax deductions
- Allocating income disproportionately to reward sweat equity or other non-cash contributions
- Shifting allocations over time as partners' contributions and roles change
Guaranteed Payments
Guaranteed payments are fixed amounts paid to partners for services or capital, regardless of partnership income. They function like a salary from a tax perspective:
- Deductible by the partnership as a business expense
- Taxable to the receiving partner as ordinary income
- Subject to self-employment tax for the receiving partner
- Paid before profit allocations are calculated
Guaranteed payments provide income predictability for working partners while preserving the flexibility of profit-based compensation for all partners.
Capital Gains and Losses
When a partnership sells assets, the resulting capital gains or losses pass through to partners. The character of the gain (short-term vs. long-term) is determined at the partnership level and maintained on each partner's K-1.
Section 751 "Hot Assets"
When a partner sells their partnership interest, some of the gain may be reclassified as ordinary income (rather than capital gain) if the partnership holds "hot assets" — primarily unrealized receivables and inventory. This can significantly increase the selling partner's tax bill.
Basis and the Impact on Gains
Each partner's tax basis in their partnership interest determines their gain or loss when they sell or receive distributions. Basis is affected by:
- Initial capital contributions
- Share of partnership liabilities
- Allocated income (increases basis)
- Allocated losses (decreases basis)
- Distributions received (decreases basis)
- Additional contributions (increases basis)
Partners cannot deduct losses that exceed their tax basis in the partnership interest.
Partners should track their outside basis in the partnership carefully. Unlike corporate shareholders, partners don't have a simple stock basis — partnership basis changes every year with income allocations, distributions, and liability changes.
State Tax Considerations
State Income Tax
Most states follow the federal pass-through model, but there are exceptions and variations:
- Some states impose an entity-level tax on partnerships (in addition to partner-level tax)
- Several states have adopted optional pass-through entity taxes (PTET) that allow partnerships to pay state tax at the entity level, enabling partners to deduct state taxes beyond the $10,000 SALT cap
- Partners may owe state income tax in multiple states if the partnership operates across state lines
State Filing Requirements
Partnerships often must file state tax returns in every state where they do business, not just the state where they're formed. Each partner may have filing obligations in multiple states as well.
Quarterly Estimated Taxes
Unlike employees who have taxes withheld from paychecks, partners must make quarterly estimated tax payments to the IRS (and potentially to state tax authorities). Missing these payments results in penalties and interest.
Quarterly estimated payments are due:
- April 15
- June 15
- September 15
- January 15 of the following year
Each payment should cover approximately 25% of the partner's expected annual tax liability from all sources, including partnership income.
Tax Planning in Your Partnership Agreement
Your partnership agreement should address several tax-related provisions:
Tax Elections
Specify which tax elections the partnership will make, or give the managing partner authority to make tax elections. Common elections include:
- Method of accounting (cash vs. accrual)
- Depreciation methods
- Section 754 election (for adjusting basis when partnership interests are transferred)
- Pass-through entity tax elections
Tax Matters Partner
Designate a "partnership representative" (formerly called the tax matters partner) who has authority to deal with the IRS on behalf of the partnership for audit purposes. Under the Bipartisan Budget Act rules, this representative has significant power, including the ability to bind partners to audit adjustments.
Tax Distributions
Include a provision requiring minimum distributions sufficient to cover each partner's tax liability on allocated partnership income.
Allocation Provisions
Detailed allocation provisions that comply with the substantial economic effect rules, including:
- How partnership income and losses are allocated
- Special allocations for contributed property
- Allocation of nonrecourse deductions
- Qualified income offset provisions
- Minimum gain chargeback provisions
Common Tax Mistakes Partnerships Make
- Not making quarterly estimated payments — Leading to penalties and cash flow problems
- Ignoring phantom income — Partners owe tax on allocated income whether or not it's distributed
- Improper special allocations — Allocations that lack substantial economic effect can be reclassified by the IRS
- Failing to track basis — Partners need to know their basis to properly report income and claim deductions
- Missing state filing requirements — Multi-state operations create filing obligations in every state of operation
Building Tax-Smart Partnership Provisions
Tax considerations should inform your partnership agreement from the start. The allocation provisions, distribution policies, and tax election authorities you establish can save partners significant money and prevent costly disputes.
