You get a Schedule K-1 from the partnership, S corporation, estate, or trust you have an interest in. The IRS does not send K-1s to individual taxpayers, and neither does your own tax preparer. The entity itself, or the accountant who prepared its return, produces the K-1 after finishing the entity’s tax return and then delivers it to you, usually through an investor portal or by mail. If yours hasn’t shown up, the entity is who you call.
Which Entity Sends Your K-1
There are three versions of the Schedule K-1, and identifying which one applies to you tells you exactly who is responsible for getting it to you.
A partnership files Form 1065 and issues a K-1 to each partner. This covers limited partnerships, most LLCs, and publicly traded partnerships. The general partner or the entity’s tax accountant handles distribution.1Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income
An S corporation files Form 1120-S and sends each shareholder a K-1 reporting their share of the company’s tax items. A corporate officer or the outside accountant typically distributes these.2Internal Revenue Service. About Form 1120-S, U.S. Income Tax Return for an S Corporation
An estate or trust that distributes income to beneficiaries files Form 1041 and issues a K-1 to each beneficiary. The executor of the estate or the trustee is the person to contact.3Internal Revenue Service. About Form 1041, U.S. Income Tax Return for Estates and Trusts
You may also see a Schedule K-3 alongside your K-1 if the entity has foreign-source income or paid foreign taxes. The K-3 reports the international items you need to claim a foreign tax credit.4Internal Revenue Service. 2025 Partner’s Instructions for Schedule K-3 (Form 1065) Not every K-1 recipient gets one; partnerships that qualify for a domestic filing exception can skip it.
Where to Look for Your K-1
Many entities no longer mail paper K-1s. If you invest through a large fund or a publicly traded partnership, start on the entity’s investor portal. These secure sites usually host the current year’s K-1 along with several prior years, and the login is typically the same one you use for distribution statements.
Publicly traded partnerships and master limited partnerships often distribute K-1s through third-party tax package websites. The investor relations page of the entity links to the correct site. If you don’t remember which one, searching the entity’s name with “K-1 tax package” almost always turns up the right landing page.
For smaller partnerships, S corporations, and trusts, delivery is more variable. The K-1 may come by mail, by email as a PDF, or through a secure client portal run by the entity’s CPA firm. If the entity sent you a K-1 last year, look at how that copy arrived and check the same channel first.
If you want to confirm what the IRS itself has on file, your IRS online account at irs.gov lets you view certain information return documents that have been reported to the agency.5Internal Revenue Service. Get Your Tax Records and Transcripts It isn’t a substitute for the full K-1, but it can tell you whether the entity has filed and what figures were reported.
When to Expect It
K-1s arrive later than W-2s and 1099s because the entity has to finish its own return first. Your share can’t be calculated until the entity’s numbers are final.
Partnerships and S corporations must file their returns, and deliver K-1s to investors, by the 15th day of the third month after their tax year ends. For calendar-year entities, that is March 15.6Internal Revenue Service. Publication 509 (2026), Tax Calendars Estates and trusts have until the 15th day of the fourth month, which is April 15 for calendar-year filers.7Internal Revenue Service. Forms 1041 and 1041-A: When to File
Entities can file Form 7004 for an automatic six-month extension of their own deadline.8Internal Revenue Service. About Form 7004, Application for Automatic Extension of Time to File Certain Business Income Tax, Information, and Other Returns A partnership or S corporation that extends pushes its deadline to September 15, and a trust or estate that extends generally pushes to late September or early October. If you invest in a fund or master limited partnership, expect to wait.
What to Do When Your K-1 Doesn’t Arrive
Once the expected delivery window has passed, work through these steps in order.
- Contact the entity directly. Reach out to the general partner, corporate officer, trustee, or investor relations department. A prior-year K-1 or the operating agreement usually lists the right contact. Ask whether the entity filed an extension and when K-1s are expected.
- Verify your address. A mailed K-1 may have gone to an old address, and an electronic copy can end up in a spam folder. Confirm the entity has your current contact information.
- Contact the accountant. The CPA firm that prepared the entity’s return often handles the actual printing and mailing. An emailed PDF from them is usually faster than waiting for a reprint.
- Put it in writing. If calls and emails aren’t producing results, send a written request specifying the K-1 form number and tax year. A documented paper trail helps if you later need to request penalty relief from the IRS.
Entities that fail to furnish K-1s on time face penalties of $60 to $340 per form depending on how late the delivery is, and up to $680 per form for intentional failures.9Internal Revenue Service. 20.1.7 Information Return Penalties Mentioning that in your follow-up sometimes moves things along.
Filing Your Own Return While You Wait
If April 15 is approaching and your K-1 still hasn’t arrived, file Form 4868 to request an automatic six-month extension for your personal return. That pushes your filing deadline to October 15 and eliminates the failure-to-file penalty, which is the steeper of the two late penalties.10Internal Revenue Service. Get an Extension to File Your Tax Return
The extension only covers filing, not payment. If you owe tax and don’t pay by April 15, the IRS charges a failure-to-pay penalty of 0.5% of the unpaid balance for each month the payment is late, up to a maximum of 25%.11Internal Revenue Service. Failure to Pay Penalty Interest accrues on top of that. To avoid it, send an estimated payment with your Form 4868.
Estimating the Payment
The simplest baseline is last year’s K-1. If the entity’s income was roughly stable, prior-year numbers give you a reasonable estimate. Any quarterly financial statements or year-end estimates the entity sent out before the K-1 was finalized are also useful inputs.
Two safe harbors protect you from the underpayment penalty. You avoid it if your total payments and withholding equal at least 90% of the current year’s tax, or at least 100% of the prior year’s tax. If your adjusted gross income last year exceeded $150,000 ($75,000 if married filing separately), the second threshold rises to 110% of the prior year’s tax.12Internal Revenue Service. Estimated Tax For K-1 recipients waiting on late forms, the prior-year safe harbor is the practical target because you already know the number. Any excess comes back as a refund when you file the completed return.
When the K-1 Never Comes or Comes Wrong
Sometimes a K-1 simply never arrives. The entity dissolved, the preparer went out of business, or the responsible party won’t respond. If you’ve reached your filing deadline, including any extension, and still don’t have the form, the IRS expects you to file using your best estimate of the K-1 income and attach Form 8082 to notify the agency that you’re reporting amounts inconsistently with what the entity may have reported.13Internal Revenue Service. Instructions for Form 8082, Notice of Inconsistent Treatment or Administrative Adjustment Request (AAR) Check the inconsistent treatment box in Part I and explain in Part III that you didn’t receive the K-1. Skipping this step is risky: if the IRS later adjusts your return to match the entity’s filing, the resulting deficiency and penalties can be assessed immediately without the usual notice process.
Corrected K-1s are common, especially when the entity amends its own return. If a corrected K-1 arrives after you’ve already filed and the changes affect your tax liability, file Form 1040-X to amend your return, explain in Part II that you received a corrected K-1, and attach the new schedule.14Internal Revenue Service. Instructions for Form 1040-X
If you believe the K-1 itself is wrong, contact the entity first, because many errors get resolved with a corrected K-1 before you need to involve the IRS. If that fails, partnership partners can file Form 8082 with their return to report amounts differently from what the partnership reported.13Internal Revenue Service. Instructions for Form 8082, Notice of Inconsistent Treatment or Administrative Adjustment Request (AAR) S corporation shareholders don’t have that option and must file an amended return instead.
If a late or incorrect K-1 causes an underpayment that wasn’t your fault, you may qualify for penalty relief. The IRS considers whether you made a reasonable effort to comply and whether the problem was outside your control.15Internal Revenue Service. Penalty Relief
