Yes. Partners are taxed on retained earnings in a partnership the same year those earnings are generated, even if the partnership distributes nothing. Federal tax law treats the partnership as a conduit rather than a taxpayer, so each partner’s allocated share of the year’s income lands on their personal return whether or not any cash actually changed hands.1eCFR. 26 CFR 1.701-1 – Partners, Not Partnership, Subject to Tax A management decision to hold profits back for working capital, debt paydown, or expansion has no effect on when the tax comes due.
This is the opposite of how a C-corporation works. A C-corp can stockpile profits internally and its shareholders owe nothing until the corporation actually pays a dividend. Partners get no such shelter. The partnership files Form 1065, which is purely informational, and the income flows through to each partner’s Form 1040 via Schedule K-1.2Internal Revenue Service.

How Your Share of Retained Income Is Determined
The amount you owe tax on is your “distributive share,” meaning the portion of partnership income allocated to you under the partnership agreement.3Office of the Law Revision Counsel. 26 USC 704 – Partners Distributive Share If the agreement gives you 30% of profits, you report 30% of the partnership’s taxable income on your return regardless of how much cash you actually took home. If the agreement doesn’t specify allocation percentages, or if the allocations lack what the IRS calls “substantial economic effect,” the IRS determines your share based on all the facts and circumstances of your actual interest in the partnership.
The partnership reports your share on Schedule K-1 (Form 1065), which breaks the numbers into categories: ordinary business income, guaranteed payments for services or capital, interest, dividends, capital gains, rental income, and various deductions.4Internal Revenue Service. Partners Instructions for Schedule K-1 Form 1065 Each category keeps its character on your return. Long-term capital gains recognized by the partnership stay long-term capital gains for you. Ordinary income stays ordinary.5Office of the Law Revision Counsel. 26 USC 702 – Income and Credits of Partner That matters, because different types of income face different tax rates.
Partnerships must issue K-1s by the 15th day of the third month after their tax year ends, which is March 15 for calendar-year partnerships.6Internal Revenue Service. Publication 509 (2026), Tax Calendars Late K-1s are common, and they can force you to either file an extension or estimate your numbers and amend later.
The Phantom Income Problem
When the partnership retains everything, the income allocated to you on the K-1 becomes what practitioners call phantom income: taxable to you, but never delivered. You still owe the full tax bill from personal funds. That bill often has three parts.
Regular Income Tax
Your distributive share is taxed at your marginal federal rate. State income tax typically applies as well, depending on where you live and where the partnership operates.
Self-Employment Tax
General partners and most LLC members who actively participate in the business owe self-employment tax on their share of ordinary business income. The combined self-employment rate for 2026 is 15.3%: 12.4% for Social Security on earnings up to $184,500, plus 2.9% for Medicare on all earnings with no cap.7Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet High earners pay an additional 0.9% Medicare surtax on self-employment income above $200,000 ($250,000 for joint filers). On $200,000 of ordinary business income, self-employment tax alone runs roughly $28,300 before regular income tax enters the picture.
Limited partners have historically been exempt from self-employment tax on their distributive share, though not on guaranteed payments for services. In early 2026, the Fifth Circuit reinforced that exclusion for partners with limited liability under state law. That ruling applies directly only in Texas, Louisiana, and Mississippi, and it addressed limited partnerships specifically. If you’re an active LLC member outside those states, expect the IRS to treat your distributive share as subject to self-employment tax.
Net Investment Income Tax
Partners who don’t materially participate face an additional 3.8% net investment income tax on their share of partnership income once modified adjusted gross income exceeds $200,000 for single filers or $250,000 for joint filers.8Internal Revenue Service. Questions and Answers on the Net Investment Income Tax Those thresholds are not indexed for inflation. Active operators generally escape this surcharge on ordinary business income; passive investors don’t.
Quarterly Estimated Payments
Because no employer is withholding on partnership income, you’re responsible for quarterly estimated payments. If you expect to owe $1,000 or more at filing, estimated payments are effectively mandatory.9Internal Revenue Service. Estimated Taxes The quarterly deadlines typically fall on April 15, June 15, September 15, and January 15 of the following year. Underpaying triggers a penalty on the shortfall for each quarter.10Office of the Law Revision Counsel. 26 USC 6654 – Failure by Individual to Pay Estimated Income Tax
You can generally avoid the penalty through either safe harbor: pay at least 90% of the current year’s total tax, or pay 100% of last year’s total tax. If your adjusted gross income last year exceeded $150,000, the second safe harbor bumps up to 110%.11Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty Partners relying on last year’s safe harbor sometimes find their estimated payments wildly insufficient when the current year’s income spikes, leaving a large balance due at filing time.
The 20% QBI Deduction Softens the Blow
One partial offset: eligible partners can deduct up to 20% of their qualified business income from the partnership under Section 199A.12Office of the Law Revision Counsel. 26 US Code 199A – Qualified Business Income The deduction is calculated at the individual partner level and applies whether or not the income was distributed. The full 20% is available without restriction to partners whose total taxable income falls below roughly $201,750 for single filers or $403,500 for joint filers in 2026. Above those thresholds, limitations kick in based on W-2 wages the business pays and the unadjusted basis of its qualified property, and partners in specified service businesses like law, accounting, consulting, medicine, and financial services face a phase-out that can eliminate the deduction entirely. The One Big Beautiful Bill Act, signed in mid-2025, made this deduction permanent.
Basis: Why You Don’t Get Taxed Twice
The tax code uses a tracking mechanism called “outside basis” to record each partner’s after-tax investment in the partnership. When you pay tax on income the partnership retained, your outside basis goes up by that amount.13Office of the Law Revision Counsel. 26 US Code 705 – Determination of Basis of Partners Interest The logic is simple: you already paid tax on that income with your own money, so the tax system credits you with more invested in the partnership.
Basis also increases when your share of partnership liabilities grows, because the code treats an increase in your share of debt as a deemed cash contribution.14Office of the Law Revision Counsel. 26 US Code 752 – Treatment of Certain Liabilities Basis decreases when you receive distributions, when the partnership allocates losses to you, or when your share of liabilities drops. Basis can never go below zero.
Without these adjustments, you’d effectively pay tax twice on the same dollar: once when it was allocated on the K-1, and again when you finally received the cash or sold your interest. A side benefit worth knowing: outside basis also caps how much of the partnership’s losses you can deduct in a given year. If the partnership allocates $50,000 in losses to you but your outside basis is only $30,000, you deduct $30,000. The remaining $20,000 suspends and carries forward until basis grows enough to absorb it.
Tax Distribution Clauses in the Partnership Agreement
Because the phantom income problem is common, well-drafted partnership agreements address it directly through tax distribution provisions. A typical clause requires the partnership to distribute enough cash each year for partners to cover the tax on their allocated income.
The mechanics are straightforward. The clause multiplies each partner’s allocated taxable income by an assumed tax rate, then distributes at least that amount. These distributions are usually treated as advances against future profit distributions, so they don’t shift the economics between partners; they simply prevent the cash-flow crunch of paying tax on retained earnings out of pocket.
The assumed rate is a real negotiation point. Partnerships often use a blended rate combining the top federal individual rate of 37%, the 3.8% net investment income tax, and an estimated state rate. A ceiling around 45% is a widely used benchmark. Whether to fold the 3.8% NIIT into the assumed rate is contested, since it applies only above certain income thresholds and only where the income is passive to the partner.
If you’re joining a partnership, particularly as a minority partner, read the operating agreement for a tax distribution clause before you sign. Without one, you depend entirely on the managing partners’ discretion to release cash. A strong year with full retention can leave you scrambling to cover a five- or six-figure tax bill with no offsetting income.
When the Retained Cash Finally Comes Out
A cash distribution of previously retained earnings is generally not a taxable event. You already paid tax on the underlying income the year it was earned, so the distribution is a return of capital you’ve been taxed on.15GovInfo. 26 USC 731 – Extent of Recognition of Gain or Loss on Distribution Your outside basis decreases dollar-for-dollar by the cash received.16Office of the Law Revision Counsel. 26 USC 733 – Basis of Distributee Partners Interest If the partnership distributes $80,000 to you and your basis is $120,000, basis drops to $40,000 and no additional tax is due.
A distribution becomes taxable only where the cash exceeds your current outside basis. The excess is treated as gain from the sale of your partnership interest, typically capital gain.15GovInfo. 26 USC 731 – Extent of Recognition of Gain or Loss on Distribution That scenario is uncommon when basis has been tracked correctly. Where it tends to surface is when a partner has taken significant loss deductions that eroded basis, or when partnership liabilities shrank substantially, dropping basis through deemed distributions under the liability rules.
A Worked Example
Suppose you’re a 25% partner in a partnership that earns $400,000 in 2026 and retains all of it. Your K-1 shows $100,000 of ordinary business income. Here’s what happens on your side:
- You report the $100,000 on your personal return and owe federal income tax at your marginal rate, even though you received no cash.
- If you’re a general partner, you owe roughly $14,130 in self-employment tax on the $100,000 (the 15.3% combined rate on 92.35% of net self-employment earnings).
- If your total taxable income is under the QBI threshold, you can deduct up to $20,000 (20% of the $100,000), reducing the income subject to your marginal rate.
- Your outside basis increases by $100,000, preserving your ability to receive that cash tax-free later.
- You should have been making quarterly estimated payments through the year to cover both the income tax and the self-employment tax on this income.
Whenever the partnership eventually distributes that $100,000 to you, whether next year or five years from now, no additional income tax is due. Your basis simply drops by the distribution amount. The system works as designed, but only if you had the cash flow to handle the upfront tax bill in a year the business paid you nothing.
