Form 1127: Asking for More Time to Pay Due to Undue Hardship
Published November 7, 2026
Form 1127 asks the IRS for more time to pay tax. It does not extend the time to file a return. The form says you use it to request an extension of time under section 6161 to pay tax shown on a return, or an amount determined as a deficiency after an examination.
This post is general information from the form and its instructions, both dated December 2024. It does not tell you what to do in your case, and the IRS decides each request.
Filing and paying are different steps
The instructions include a chart. If you need more time to file, use Form 4868 for an automatic extension for a U.S. individual income tax return, or Form 2350 if you are a U.S. citizen abroad. Do not file Form 1127 for that purpose.
If you want to pay in monthly installments, the chart points to Form 9465, Installment Agreement Request, or to the Online Payment Agreement application. Do not file Form 1127 for that either.
What undue hardship means
The instructions say undue hardship means more than an inconvenience. You must show that you would have a substantial financial loss if you paid the tax on the due date. The instructions give an example: selling property quickly for much less than it is worth.
Part II asks for a detailed explanation of the hardship. The form says an extension will not be granted if you give only a general statement of hardship.
Who can file
The instructions say you can file Form 1127 if you will owe certain taxes and paying on time would cause undue hardship. The list includes income taxes, self-employment taxes, and withheld taxes on nonresident aliens and foreign corporations. It also includes certain taxes on private foundations and other tax-exempt organizations.
The two statements you must attach
Part III lists two attachments. You must check both boxes, or the application will not be accepted.
- A statement of your assets and liabilities at the end of last month. It shows book and market values, and whether securities are listed or unlisted.
- An itemized list of your income and expenses for each of the 3 months before the due date of the tax.
Part I: the dates and the amount
Part I asks for the dates of the extension, the amount of tax you will pay, and the form or tax year it relates to. For a calendar-year tax, enter the tax year. For a fiscal-year tax, enter the ending month, day, and year.
The instructions say the date you propose to pay can be up to 6 months from the due date of the return, not counting extensions. If the request covers a deficiency, the date can be up to 18 months from the date payment is due. The instructions say the IRS may allow another 12 months in exceptional circumstances.
When to file
The instructions say to file as soon as you know you owe a tax you cannot pay without undue hardship. For tax on a return that is not yet due, the form must be received on or before the due date of that return, not counting extensions. For a deficiency, it must be received on or before the due date shown on the tax bill.
What keeps running while you wait
Interest starts on any tax not paid by the due date, even if an extension is granted. The interest runs until you pay. Penalties may apply if you do not pay within the extension period. The instructions say you must pay before the extension runs out, and not wait for a bill from the IRS.
The instructions also say that a deficiency extension is not granted when the deficiency comes from negligence, intentional disregard of the rules, or fraud.
Where to file and who signs
The instructions say to send the form to the Advisory Group Manager for the area where you maintain your legal residence or principal place of business. Publication 4235 lists the addresses. Both spouses must sign a joint application. A preparer who is not the taxpayer also signs.
A checklist before you file
- Confirm the form number and tax year the request relates to.
- Write a detailed reason in Part II, with dates and facts you can support.
- Prepare the assets and liabilities statement and the 3 months of income and expenses.
- Check both boxes in Part III.
- Keep a copy of the application and every attachment.
