To report partnership distributions on your tax return, start with Box 19 of the Schedule K-1 (Form 1065) the partnership sends you. In most cases the distribution itself is not entered as income anywhere on your Form 1040. Instead, it reduces your adjusted basis in the partnership interest, and tax is owed only when the cash or marketable securities you received exceed that basis. When that happens, the excess is reported as a capital gain on Form 8949 and Schedule D. Your share of partnership income, which is a separate figure from the distribution, flows onto Schedule E regardless of whether any cash actually left the partnership.
What Your K-1 Tells You About the Distribution
The Schedule K-1 breaks down your share of the partnership’s income, deductions, credits, and distributions for the year. For calendar-year partnerships, it is due to you by March 15.1Internal Revenue Service. Instructions for Form 1065 (2025)
Box 19 is where distributions appear. Code A covers cash and marketable securities (other than amounts received for services), Code C covers other property, and Codes F and G report distributions received specifically as compensation for services you performed.2Internal Revenue Service. Partner’s Instructions for Schedule K-1 (Form 1065) (2025) – Section: Box 19 Distributions
Item L of the K-1 shows a tax-basis capital account, but the IRS is explicit that this figure is not your adjusted basis. You are responsible for tracking basis yourself, and if the IRS challenges a number, the burden of proof is on you.3IRS.gov. Partner’s Outside Basis
Update Your Basis Before You File
Your adjusted basis is a running balance that starts with your initial contribution and moves each year with partnership activity. Under 26 USC 705, basis increases by your share of taxable income, tax-exempt income, and certain depletion deductions, and decreases by distributions, your share of losses, and nondeductible expenses.4Office of the Law Revision Counsel. 26 USC 705 – Determination of Basis of Partner’s Interest
The reason a cash distribution normally has no immediate tax consequence is that partnership income already flowed through to you on the K-1 and was taxed whether or not you took cash. A later withdrawal is treated as a return of money you were already taxed on, not new income.
Order matters at year-end. Basis increases first, from your share of the current year’s income, and then decreases for distributions. That sequencing can keep a distribution from exceeding basis when it would appear to if you ran the numbers in the other order.
What Goes on Schedule E, and What Doesn’t
Partnership activity is reported on Part II of Schedule E (Form 1040).5Internal Revenue Service. 2025 Instructions for Schedule E (Form 1040) – Supplemental Income and Loss For each partnership, you enter the income or loss from your K-1 on line 28, splitting passive amounts from nonpassive amounts into the correct columns. The employer identification number on Schedule E must match the K-1 exactly.
The Box 19 distribution figure is not a Schedule E line item. It is informational: it tells you how much basis to subtract in your own records. The taxable numbers that reach Schedule E and then Form 1040 come from the other K-1 boxes reporting your share of income, gains, deductions, and credits.
When a Distribution Becomes Taxable
A cash distribution is taxable to the extent it exceeds your adjusted basis immediately before the distribution. Under 26 USC 731, the excess is treated as gain from the sale of your partnership interest.6Office of the Law Revision Counsel. 26 USC 731 – Extent of Recognition of Gain or Loss on Distribution If your basis is $50,000 and you receive $65,000 in cash, you have a $15,000 gain. Basis cannot go below zero; the overshoot is what you report.
Report the gain on Form 8949 and Schedule D (Form 1040).7Internal Revenue Service. 2025 Instructions for Schedule D (Form 1040) The holding period of your partnership interest determines the rate. Held more than one year, the gain is long-term and taxed at 0%, 15%, or 20% depending on taxable income and filing status.8Internal Revenue Service. Topic No. 409, Capital Gains and Losses Held a year or less, it is short-term and taxed at ordinary rates that reach 37% at the top bracket.9Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
Net Investment Income Tax
A capital gain from an excess distribution can also trigger the 3.8% Net Investment Income Tax if your modified adjusted gross income exceeds $250,000 for married joint filers, $200,000 for single filers, or $125,000 for married filing separately. These thresholds are not indexed for inflation. The tax is calculated on Form 8960 and added to your regular liability.10Internal Revenue Service. Topic No. 559, Net Investment Income Tax
Hot Assets Can Convert Capital Gain to Ordinary Income
If the partnership holds unrealized receivables or substantially appreciated inventory, the portion of your gain attributable to those “hot assets” is ordinary income rather than capital gain.11Office of the Law Revision Counsel. 26 U.S. Code 751 – Unrealized Receivables and Inventory Items Unrealized receivables include rights to payment for delivered goods or services and certain depreciation recapture items. Inventory is substantially appreciated when its fair market value exceeds 120% of the partnership’s adjusted basis in it. Because ordinary rates run higher than long-term capital gain rates, this recharacterization can meaningfully increase what you owe. The partnership should give you enough information alongside the K-1 to run the calculation, but the balance sheet or a tax professional may be needed to work through it.
Property and Marketable Securities
Distributions of property other than cash generally trigger no gain. Your basis in the distributed property carries over from the partnership’s basis, capped at your remaining partnership basis.12Office of the Law Revision Counsel. 26 U.S. Code 732 – Basis of Distributed Property Other Than Money If the partnership hands you equipment with a $30,000 basis and your partnership basis is $25,000, your basis in the equipment is $25,000 and your partnership basis becomes zero.
Marketable securities are the exception you need to watch. For the gain-recognition rule, the tax code treats them as cash at fair market value on the distribution date.6Office of the Law Revision Counsel. 26 USC 731 – Extent of Recognition of Gain or Loss on Distribution Receive $80,000 of publicly traded stock when your basis is $60,000, and you recognize a $20,000 gain, exactly as if it were cash. A narrow exception applies if you originally contributed those same securities to the partnership.
Don’t Confuse Distributions With Guaranteed Payments
If the partnership pays you a set amount for services, similar to a salary, that payment shows up in Box 4a of the K-1, not in Box 19. Guaranteed payments are ordinary income regardless of whether the partnership was profitable, and they belong in the nonpassive column on Schedule E.13Internal Revenue Service. Partner’s Instructions for Schedule K-1 (Form 1065) (2025) – Section: Box 4 Guaranteed Payments
The two follow different tax paths. A distribution reduces basis and is usually tax-free. A guaranteed payment is ordinary income that increases basis (as part of partnership income) before any distribution reduces it. Treating one as the other throws off both your reported income and your basis going forward.
Self-Employment Tax Follows Income, Not the Distribution
The distribution itself is not subject to self-employment tax. Your distributive share of ordinary business income is, if you are a general partner, whether or not any cash was actually paid out. The combined rate is 15.3% on the first $176,100 of self-employment income for 2025 (the threshold adjusts annually), with the 2.9% Medicare portion continuing on income above that.14IRS.gov. Self-Employment Tax and Partners
Limited partners are treated differently. A limited partner’s distributive share is excluded from self-employment tax, other than guaranteed payments for services actually rendered.15Office of the Law Revision Counsel. 26 USC 1402 – Definitions
Self-employment tax is calculated on Schedule SE using the ordinary business income from the K-1, not the Box 19 distribution. Skipping self-employment tax because no distribution was received is a common error; the tax follows income allocation, not cash flow.
Deadlines and Getting the Return In
The individual return for tax year 2025 is due April 15, 2026.16Internal Revenue Service. IRS Opens 2026 Filing Season With the K-1 not due to you until March 15, you have roughly a month to work it into your return. If the K-1 is late or wrong, Form 4868 buys you until October 15, but any tax owed still has to be paid by April 15 to avoid interest.
Once the K-1 income is on Schedule E and any excess-basis gain is on Form 8949 and Schedule D, the return is ready. Electronic filing is faster and gives immediate confirmation. Software will usually handle K-1 entry and basis adjustments, but the numbers should be checked against your own basis records before you submit.
Underreporting has consequences. The IRS can impose a 20% accuracy-related penalty on underpayments caused by negligence, disregard of the rules, or a substantial understatement of income tax, and 40% for gross valuation misstatements.17eCFR. 26 CFR 1.6662-2 – Accuracy-Related Penalty Keeping a clean basis worksheet from year to year is the single best protection against both overpaying and underreporting.
