IRS Form 8828 is an application for an automatic extension of time to file a tax return for certain taxpayers, such as partnerships, S corporations, and certain estates. Use it when you need more than the standard six‑month filing period.
Plain English
If you’re a partnership, S‑corp, or similar entity and the regular filing deadline isn’t enough, Form 8828 asks the IRS for extra time. You fill it out, explain why you need the extension, and wait for IRS approval before filing the actual return.
