On a Schedule K-1, income and distributions answer two different questions. K-1 income is your share of the business’s profit for the year, and you owe tax on it whether or not any money reached your bank account. A distribution is cash (or property) the business actually sent you, and by itself it usually isn’t taxable. The reason both can appear on the same form, in very different amounts, comes down to how pass-through taxation works and how your basis in the entity tracks the difference.
What K-1 Income Is and Why You Owe Tax on It
Partnerships and S corporations don’t pay federal income tax at the entity level. Each owner picks up a share of the profit or loss directly on Form 1040, even if the business kept every dollar it earned.1Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income The Schedule K-1 is how the entity tells you (and the IRS) exactly what flowed through to you for the year.
Box 1 on a partnership K-1 (Form 1065) and Box 1 on an S corporation K-1 (Form 1120-S) show your share of ordinary business income or loss. If a partnership earns $200,000 and you own 25%, your K-1 reports $50,000 of ordinary income. You owe tax on that $50,000 even if the partnership held every cent in its operating account.
Some items are broken out on their own lines so they keep their tax character. Capital gains, qualified dividends, interest, and charitable contributions each appear in separate K-1 boxes rather than getting folded into Box 1. A qualified dividend flowing through the K-1 still gets the favorable dividend rate on your return.2Internal Revenue Service. Topic No. 404, Dividends and Other Corporate Distributions
Guaranteed payments sit in a category of their own. Reported in Box 4 of a partnership K-1, these are amounts a partnership pays a partner for services or for the use of capital, calculated without regard to partnership profits. The partner reports them as ordinary income, and they’re subject to self-employment tax.3Internal Revenue Service. Publication 541, Partnerships
One detail catches many owners off guard. K-1 income is figured on tax rules, which can look quite different from the entity’s financial statements. Depreciation methods, timing of deductions, and inventory adjustments all create gaps between book profit and the number on your K-1.
What a Distribution Is
A distribution is cash or property moving from the entity to you. It’s a cash flow event, not a taxable event in itself. On a partnership K-1, distributions appear in Box 19. On an S corporation K-1, they show up in Box 16.4Internal Revenue Service. Partners Instructions for Schedule K-1 Form 1065
Because you already owe tax on K-1 income the moment it’s allocated to you, a distribution of that same money is generally tax-free. You’re pulling out earnings you’ve already been taxed on. The distribution reduces your investment in the entity for tax purposes, but it doesn’t produce a second tax bill on the same dollars.
That tax-free treatment has a ceiling, though, and the ceiling is your basis in the entity.
Why Basis Is the Bridge Between the Two
Tax basis is the running scorecard of your investment in the entity. It starts with what you contributed and adjusts each year for what the entity does and what it sends you. The simplified formula:
Starting basis + your share of income + additional contributions − your share of losses − distributions = ending basis.
Notice what income and distributions do to that number. Income raises your basis. Distributions lower it. That’s the mechanical link between the two figures on your K-1: the profit you were already taxed on becomes basis, and later distributions draw that basis back down without generating new tax.
A quick example makes the interaction concrete. Suppose you start the year with a $30,000 basis. The K-1 allocates $20,000 of income to you, raising your basis to $50,000. The entity then distributes $45,000. That distribution is entirely tax-free because it doesn’t exceed your $50,000 basis. Your ending basis is $5,000. If the distribution had been $55,000, the first $50,000 would still be tax-free, and the extra $5,000 would be a taxable capital gain.
The entity does not track your basis for you. That’s on you. One year of loose recordkeeping can cascade into incorrect loss deductions or unexpected gains on distributions for years afterward.
When a Distribution Actually Becomes Taxable
Distributions stay tax-free only up to your current basis. Anything above that becomes a taxable capital gain.
For partnerships, if cash distributed exceeds your adjusted basis, the excess is treated as gain from the sale of your partnership interest.5Office of the Law Revision Counsel. 26 U.S. Code 731 – Extent of Recognition of Gain or Loss on Distribution The same principle applies to S corporations: a distribution beyond your stock basis is taxed as a capital gain.6Internal Revenue Service. S Corporation Stock and Debt Basis If you’ve held the interest for more than a year, the excess is a long-term capital gain taxed at favorable rates.7Internal Revenue Service. Topic No. 409, Capital Gains and Losses
Any capital gain from a distribution exceeding basis flows through to Form 8949 and Schedule D on your Form 1040.6Internal Revenue Service. S Corporation Stock and Debt Basis
There’s an additional wrinkle for S corporations that were once C corporations. If the entity has accumulated earnings and profits from its C corporation years, distributions follow a layered order: first out of the accumulated adjustments account (the S corporation era earnings), then as dividends to the extent of the old C corporation earnings, and only after that do the ordinary basis-reduction rules apply. Shareholders who assume every S corporation distribution is just a return of basis can be surprised by dividend treatment on part of what they received.
Partnership vs. S Corporation: Where the Rules Diverge
The basic income-versus-distribution split works the same way for both entity types, but one difference in the basis rules changes how much room owners actually have for tax-free distributions and deductible losses.
In a partnership, your basis includes your share of the entity’s liabilities. When the partnership borrows money, each partner’s basis increases by their allocated share of that debt.8Office of the Law Revision Counsel. 26 U.S. Code 752 – Treatment of Certain Liabilities Partnership basis can therefore run well above what a partner personally put in, which means more headroom before distributions turn taxable.
S corporation shareholders get no comparable boost from entity-level borrowing. Stock basis increases only from income allocations and your own contributions. The one adjacent concept is “debt basis,” which comes from loans you personally make directly to the S corporation. A bank loan to the S corporation doesn’t lift any shareholder’s basis.6Internal Revenue Service. S Corporation Stock and Debt Basis In practice, S corporation shareholders exhaust their basis faster and are more likely to see distributions push into taxable territory.
S corporation shareholders also have a specific reporting obligation. Form 7203 is required whenever you claim a loss deduction, take a non-dividend distribution, dispose of stock, or receive a loan repayment from the corporation.9Internal Revenue Service. About Form 7203, S Corporation Shareholder Stock and Debt Basis Limitations Filling it out even in off years keeps your basis records defensible.
The self-employment tax picture also runs on entity type. General partners owe self-employment tax on their share of ordinary business income and on guaranteed payments for services. Limited partners generally owe self-employment tax only on guaranteed payments for services, not on their share of ordinary income.10Internal Revenue Service. Self-Employment Tax and Partners S corporation K-1 income is not subject to self-employment tax at all, but any shareholder who works in the business must first take reasonable W-2 compensation before pulling money out as distributions.11Internal Revenue Service. Wage Compensation for S Corporation Officers The IRS can reclassify distributions as wages if the salary is too low, and the bill for back payroll taxes, penalties, and interest can be significant.
Tax Distributions: Why the Cash Often Follows the Income
Because K-1 income triggers a real tax bill even when the entity keeps the cash, many operating agreements include a “tax distribution” clause. The clause obligates the entity to send each owner enough cash to cover the taxes generated by their K-1 allocation. Without one, an owner can end up writing a check to the IRS for income that never arrived in their account.
That’s the practical shape of the K-1 income versus distribution question. The K-1 tells you what you owe tax on. The distribution tells you what you actually got. Basis is what keeps the second from being taxed twice, and what tells you when it will be taxed anyway. Track it every year, know which entity type you’re in, and check that any distribution above basis has been reported correctly on Schedule D.
