What Happens If My K-1 Is Late — or Never Shows Up?

If you invest in partnerships, private equity, or real estate syndications, you’re probably familiar with the K-1 waiting game. Some arrive in early March. Others? Late August… or not at all.

So what do you do if your K-1 is delayed?

All of these answers and much more will be a part of our 3 Day Workshop - Stop Guessing at Your K-1 - Critical Tax Moves Savvy Investors Make

Can I File Without My K-1?

Short answer: No — not if you want your return to be accurate. Filing without a K-1 means you’re leaving off income, deductions, or losses you’re legally required to report. That’s a red flag for the IRS and could trigger penalties or amended returns later.

What Should I Do Instead?

File an extension.
If you’re still waiting on a K-1 close to the filing deadline (April 15 for individuals), the safest option is to extend your return. This gives you until October 15 to file — and avoids rushing into errors or having to amend later.

⚠️ Reminder: An extension gives you more time to file, not more time to pay. You still need to estimate and pay any taxes owed by April 15 to avoid interest.

What If I Get a K-1 After I File?

If you receive a Schedule K-1 after you've already filed your tax return, you’ll likely need to file an amended return (Form 1040-X) to report the missing information—especially if it affects your tax liability. However, whether you need to amend depends on the nature of the K-1. If it reports income, or if the loss is active, an amendment is usually necessary. On the other hand, if the K-1 shows passive losses, you might be able to avoid filing an amended return by simply updating Form 8582, which handles passive activity limitations. This is advanced territory, so proceed carefully—or better yet, consult a CPA who knows their way around these rules.

What If I Never Get a K-1?

  1. Contact the Sponsor or Manager
    Reach out to the investment sponsor, fund manager, or investment platform to confirm the status of the Schedule K-1. It could be delayed, misdelivered, or available online.

  2. Document All Communication Attempts
    Keep records of emails, calls, and any written requests asking for the K-1. This helps demonstrate good faith efforts to obtain the tax document.

  3. Estimate Income if Necessary
    If no K-1 is received and you're sure there was taxable activity, you're still responsible for reporting it. Your CPA can:

    • Estimate income based on prior-year K-1s

    • Use cash distributions or internal reports

    • Include a disclosure with your tax return explaining the estimate and that the K-1 was not provided

  4. File an Extension (if needed)
    If the K-1 is delayed and you're trying to avoid amending your return later, consider filing for an extension (Form 4868) to allow more time.

  5. Inform the IRS with a Statement (Optional but Helpful)
    While there’s no official IRS form to “report” a missing K-1, your CPA can include a Form 8275 (Disclosure Statement) or just attach a written explanation with the return. This protects you in case of an audit by showing that:

    • You attempted to obtain the K-1

    • You made a reasonable estimate

    • You were not willfully hiding income

Why This Matters

Late or missing K-1s aren’t just annoying — they can cost you:

  • IRS penalties for underreporting income

  • Amended return fees

  • Missed deductions or credits

  • Increased audit risk

That’s why we always recommend extending when a K-1 is missing — and why investors should track down missing K-1s proactively, not passively.
