Form 1127 (Rev. December 2024) – 2023 Tax Year Checklist
Purpose
Form 1127 is the official Application for Extension of Time to Pay federal tax when immediate payment would cause undue hardship to the liable taxpayer. Under Treasury Regulation, undue hardship means more than inconvenience—you must demonstrate substantial financial loss, such as selling property at a sacrifice price. The Internal Revenue Service requires detailed financial documentation, including asset and liability statements, as well as three months of itemized income records, to evaluate whether an extension should be granted.
Filing Steps
1. Confirm Form 1127 eligibility for your tax type
Verify that your tax qualifies for extension of time consideration. Eligible taxes include income taxes, self-employment taxes, withheld taxes on nonresident aliens and foreign corporations, taxes on private foundations and tax-exempt organizations, taxes on qualified investment entities, greenmail taxes, structured settlement factoring taxes, and gift taxes.
2. Complete Part I with the correct tax year reference
Enter the original due date of your 2023 return or deficiency notice without considering filing extensions. Specify your proposed payment date, which may extend up to 6 months beyond the return due date for taxes shown on returns, or up to 18 months from the deficiency payment owing date for amounts determined by Field Collection or examination.
Enter the exact tax amount owed and check only one box—either the tax shown on the return or the amount determined as a deficiency. Include the correct form number and calendar year 2023 or the fiscal year ending date. The Internal Revenue Service tax examiner will verify this information against the Master File when processing your application.
3. Document undue hardship in Part II with substantive detail
Provide a detailed explanation demonstrating undue hardship as defined under the Treasury Regulation. Generic statements like “I cannot afford payment” are insufficient and result in denial. Instead, describe specific circumstances such as assets requiring liquidation, current market conditions causing losses, business operations disrupted, or quantifiable financial harm.
The Internal Revenue Service determines whether the payment results in a substantial financial loss beyond mere inconvenience. A tax examiner will review your explanation against your financial documentation, so ensure consistency between your narrative and the attached statements of assets and liabilities.
4. Prepare an asset and liability statement as of the end of the last month
Create a comprehensive statement that shows the book value and market value for all assets. Indicate whether securities are listed or unlisted. Include all liabilities with current balances. This statement should be dated as of the end of the last completed month before filing Form 1127.
Example dating rule
If filing in March 2024, date your assets and liabilities statement February 29, 2024.
Include all property owned individually or as a single-member owner of entities, and identify any secondary taxpayer interests in jointly held assets.
5. Compile a three-month income and expense record
Itemize income and expenses for each of the three calendar months immediately preceding your tax due date. Each month must be itemized separately—combined statements are not acceptable.
Example for a typical 2023 return due date
For a 2023 return due April 15, 2024, provide detailed records for January, February, and March 2024.
List specific income sources, including wages, Social Security benefits, investment income, and business receipts—detail expense categories with actual amounts for each month. The Internal Revenue Service uses this to verify your hardship claim and assess payment ability within the requested extension period.
6. Verify both required attachments are included before submission
Confirm you have attached both required documents: The assets and liabilities statement showing book and market values, and the three-month itemized income and expense list with separate monthly detail.
Part III requires checking both boxes to certify that these attachments are included. Applications without both attachments will not be accepted and will be returned to you.
Missing either attachment results in automatic denial without further review by the tax examiner. Incomplete submissions delay processing and may affect your appeal period for challenging the underlying tax liability.
7. Ensure proper signature and verification
All signatures must be original. If the 2023 tax is joint or the deficiency is assessed jointly, both the liable taxpayer and spouse must sign and date the form. If only one spouse can sign due to incapacity, refer to Treasury publication guidance. If a preparer completed the form, that person must also sign, date, and provide credentials.
Signatures confirm, under penalty of perjury, that the statements are accurate and complete. Unsigned applications cannot be processed and will be returned, potentially causing the O Freeze code to remain on your Master File account until a proper submission is made.
8. Identify the correct mailing address
Gift tax applications (Form 709 or Form 709-NA)
Send your application for extension to:
Department of the Treasury
Internal Revenue Service
Stop 824G
7940 Kentucky Drive
Florence, KY 41042-2915
All other taxes (including income tax and self-employment tax)
Consult Publication 4235, Collection Advisory Offices Contact Information, to locate the Advisory Group Manager address for your legal residence or principal place of business. The Internal Revenue Service maintains separate processing locations, and mailing to incorrect addresses delays consideration. Field Collection offices do not process Form 1127—only designated Advisory Group offices handle these applications.
Mailing address reminder for gift tax returns
The Florence address for Form 1127 is specifically for extension of time payment requests. Original gift tax returns go to Kansas City, Missouri. Only supplemental or amended returns go to Florence. Verify your current mailing addresses, as the Internal Revenue Service periodically updates its processing locations.
9. Note interest and penalty accrual rules
Interest accrues on the unpaid 2023 tax from the original due date and continues until full payment is made, regardless of whether an extension is granted. Under Treasury Regulation, granting extensions does not suspend the accumulation of interest. The Internal Revenue Service calculates interest daily using the federal short-term rate plus 3 percent.
Penalties apply if tax remains unpaid after the extension expires. Extensions provide additional time to pay but do not eliminate interest charges. Calculate all interest and penalties along with the tax liability to avoid additional notices from Field Collection.
10. Understand extension period limits
For tax shown on your 2023 return, extension of time generally does not exceed 6 months from the original due date. Extensions longer than 6 months may be granted only if you are outside the United States at the time of application. For deficiency amounts, extensions are limited to 18 months from the payment due date. In exceptional circumstances, an additional 12 months may be granted, for a total of up to 30 months.
The Internal Revenue Service will not grant extensions for deficiencies from negligence, intentional disregard of rules, or fraud. Under Title 26 provisions, the liable taxpayer bears the burden of demonstrating that the deficiency did not arise from prohibited causes. If your case involves disputed facts, consider whether a Tax Court petition during the appeal period is more appropriate than requesting an extension of time for payment.
