Schedule K-1
Definition
Schedule K-1 is the IRS form that a pass-through entity, a partnership, a limited liability company taxed as a partnership, an S corporation, an estate or a trust, issues to each of its owners to report that owner's share of the entity's income, gains, losses, deductions and credits for the tax year. The entity itself pays no federal income tax; each item flows through to the owner's return, keeping its character (ordinary income, interest, dividends, long-term capital gain, depreciation, foreign taxes) and, for real estate and energy, its state source. Most private funds, feeder and access funds, real estate syndications, single-asset SPVs, litigation finance partnerships and mineral royalty vehicles sold to individuals are partnerships for tax purposes and issue a K-1 (Form 1065, Schedule K-1); the alternative, a Form 1099 from a corporation, REIT or interval fund, reports only what was paid to the investor.
Why it matters
The K-1 is where the after-tax return of an alternative investment is decided, and it arrives after the investment is made. A 9 percent private credit yield reported as ordinary income on a K-1 in September, with estimated tax due in April on a number the fund had not yet sent, is a different investment from a 7 percent qualified dividend on a 1099 in January. Phantom income, multi-state filings, UBTI in a retirement account and a return that cannot be filed until October are costs that never appear in a pitch deck's return table and that many first-time platform investors discover the following spring.
Common misconceptions
- •A K-1 is not a bill and not a payment record. It reports your share of the partnership's tax items, which may be more or less than the cash you received.
- •A late K-1 is not the fund's failure. Funds that own other partnerships cannot complete their K-1s until the underlying ones arrive; the delay is structural, and the answer is an extension.
- •A loss on a K-1 is not always deductible. Passive-activity, at-risk and basis rules can suspend losses until there is passive income or a sale to use them against.
- •Tax-exempt accounts are not exempt from everything. UBTI from leveraged real estate or operating businesses is taxable inside an IRA and requires a separate return.
Technical details
Worked example: a $100,000 real estate LLC interest
Year 1: the property earns $9,000 of net rental income attributable to the investor, less $12,000 of allocated depreciation. The K-1 shows a $3,000 net rental loss in box 2 and a $6,000 cash distribution in box 19. The investor received $6,000 and reports a loss, which is suspended as passive unless there is other passive income.
Year 5: the property is sold. The K-1 shows a $40,000 Section 1231 gain in box 10, of which $15,000 is unrecaptured Section 1250 gain taxed at up to 25 percent, plus the release of the suspended passive losses. The investor receives $130,000 of sale proceeds; the taxable gain is measured against a basis reduced by five years of depreciation.
The property is in a state with a nonresident filing requirement; the investor files there in years 1 and 5 unless the fund files a composite return.
Timing and the extension routine
Partnership return due March 15; automatic extension to September 15. Most private funds use it.
Investors extend their own returns to October 15 (Form 4868) and pay estimated tax by April 15 based on the prior year or the fund's estimate; underpayment carries interest.
Amended K-1s arrive when an underlying partnership or portfolio company revises its numbers; an amended personal return may follow.
Platforms that promise K-1s by March are describing single-asset SPVs with simple books; funds of funds and feeders cannot.
Character, basis and the boxes that matter
Character flows through: ordinary income (box 1, box 5 interest) is taxed at ordinary rates; qualified dividends (box 6b) and long-term gains (box 9a) at capital rates; Section 1231 gains (box 10) as capital gains with depreciation recapture rules.
Basis: the investor's tax basis starts at cost, rises with allocated income and contributions, falls with losses and distributions; distributions above basis are taxable, and losses beyond basis are suspended. Part II of the K-1 tracks the capital account and share of liabilities.
Box 20 codes carry the items that trigger other forms: UBTI (code V), Section 199A qualified business income (code Z), foreign taxes, and the at-risk and passive information.
Box 19 distributions are informational; they are not income and not the amount to report.
Special situations
Feeders and access funds: the feeder issues one K-1 that consolidates the master fund's items; timing is later and the feeder may report state items from every state the master touches.
Blocker corporations: funds sold to IRAs and foreign investors often interpose a corporation that pays entity-level tax and converts UBTI or effectively connected income into dividends; the investor receives a 1099 or nothing until the blocker distributes.
Publicly traded partnerships: K-1s from listed MLPs and some exchange-traded commodity funds, with UBTI and state issues on a scale that surprises IRA holders.
Series LLCs and single-asset SPVs: usually one K-1 per series; simple books, early delivery, but often income in states the investor has never visited.
Reg A and interval fund products: not K-1s; corporations, REITs and RICs issue 1099-DIV and 1099-B, which is one reason platforms structure retail products that way.
Diligence questions before investing
Is the vehicle a partnership (K-1) or a corporation, REIT or RIC (1099)? The subscription documents say which.
When were last year's K-1s delivered, and were any amended?
Does the fund file composite state returns or withhold for nonresidents, and in how many states did it report income last year?
Can the fund generate UBTI or effectively connected income, and does it offer a blocker for retirement accounts?
Has taxable income exceeded cash distributions in any recent year, and by how much?
Frequently asked questions
- What is a Schedule K-1 for an investor?
- The form that tells you your share of a partnership's tax items so you can report them on your own return. If you invested $50,000 in a real estate fund organized as an LLC and the fund earned rental income, took depreciation and sold a property at a gain, your K-1 shows your slice of each, in separate boxes, whether or not the fund sent you any cash.
- When do K-1s come out?
- Partnerships must furnish K-1s by the due date of their own return, March 15 for calendar-year partnerships, but most private funds file for an extension to September 15 and send K-1s between April and September. Funds of funds and feeders, which must wait for K-1s from the funds they own, are the latest. Investors who hold K-1 investments routinely extend their personal returns to October 15 and pay estimated tax in April on the expected amount.
- Can I owe tax on a K-1 without receiving any cash?
- Yes. Taxable income is allocated to you when the partnership earns it, not when it distributes it. A private credit fund that reinvests interest, a real estate fund that sells a building and holds the proceeds, or a company that realizes a gain and retains it for reserves all produce K-1 income with no matching distribution. The reverse also happens: a distribution funded by depreciation-sheltered cash flow or by return of capital can be tax-free in the year received.
- Do I have to file state tax returns because of a K-1?
- Often. Income from real estate, operating businesses and some energy assets is sourced to the state where the property or business is, and that state can require a nonresident return from every partner with income above its threshold. A fund owning properties in six states can create six filing obligations. Many funds file composite returns or withhold on behalf of nonresident investors to spare them the filings; ask before investing.
- What is UBTI on a K-1 and why does it matter for an IRA?
- Unrelated business taxable income: income from an active business or from debt-financed property that is taxable even inside a tax-exempt account such as an IRA or a pension. A leveraged real estate fund or a fund that owns operating businesses through partnerships can generate UBTI, reported on the K-1 (box 20, code V), and an IRA with more than $1,000 of it must file Form 990-T and pay tax. Funds sold to retirement accounts often use a blocker corporation to avoid it.
- Which alternative investments issue a K-1 and which a 1099?
- K-1: private equity, venture and private credit funds structured as LPs, access and feeder funds, real estate syndications and LLC deals, single-asset SPVs, litigation finance and royalty partnerships, most series LLC offerings. 1099: REITs (including non-traded and Reg A REITs), interval funds and BDCs (which are corporations or RICs), bonds and notes issued by a corporation, and platforms that lend to you a note rather than sell you an interest. A platform's tax reporting is stated in its offering documents and is a fair thing to choose an investment by.
- What are the main boxes on a partnership K-1?
- Part III of Form 1065 Schedule K-1: box 1 ordinary business income or loss, box 2 net rental real estate income, box 5 interest, box 6 dividends, box 8 and 9a short and long-term capital gains, box 10 Section 1231 gain, box 13 deductions, box 15 credits, box 19 distributions, box 20 other information including UBTI and Section 199A data. Part II shows your capital account and your share of liabilities, which matter for basis and for deducting losses.
