If your K-3, Box 16 is checked but hasn't been issued yet, here’s how you can proceed:
Best Option — File an Extension: You can request an extension to file your tax return. This gives you additional time to receive the K-3 and ensures you have all the necessary information to complete your return accurately.
You have until October to complete and file your return.
Note that your best estimate of taxes due on your return must be paid by the original filing deadline (April 15, 2025 for tax year 2024)
Next Option — File Now and Amend Later: If you prefer to file your return now, you can do so and then file an amended return once you receive the K-3. To file now, uncheck Box 16 and e-file.
