In general—(1) Tax shown or required to be shown on return. A reasonable extension of the time for payment of the amount of any tax imposed by Chapter 42 and shown or required to be shown on any return, may be granted by the district directors and directors of the service centers at the request of the taxpayer. The period of such extension shall not be in excess of 6 months from the date fixed for payment of such tax, except that if the taxpayer is abroad the period of the extension may be in excess of 6 months.

Deficiency. The time for payment of any amount determined as a deficiency in respect of tax imposed by Chapter 42 may, at the request of the taxpayer, be extended by the internal revenue officer to whom the tax is required to be paid for a period not to exceed 18 months from the date fixed for payment of the deficiency, as shown on the notice and demand, and, in exceptional cases for a further period not in excess of 12 months. No extension of the time for payment of a deficiency shall be granted if the deficiency is due to negligence, to intentional disregard of rules and regulations, or to fraud with intent to evade tax.

Extension of time for filing distinguished. The granting of an extension of time for filing a return does not operate to extend the time for the payment of the tax or any part thereof unless so specified in the extension.

Undue hardship required for extension. An extension of the time for payment shall be granted only upon a satisfactory showing that payment on the due date of the amount with respect to which the extension is desired will result in an undue hardship. The extension will not be granted upon a general statement of hardship. The term “undue hardship” means more than an inconvenience to the taxpayer. It must appear that substantial financial loss, for example, loss due to the sale of property at a sacrifice price, will result to the taxpayer from making payment on the due date of the amount with respect to which the extension is desired. If a market exists, the sale of property at the current market price is not ordinarily considered as resulting in an undue hardship.

Application for extension. An application for an extension of the time for payment of the tax shown or required to be shown on any return, or for the payment of any amount determined as a deficiency shall be made on Form 1127 and shall be accompanied by evidence showing the undue hardship that would result to the taxpayer if the extension were refused. Such application shall also be accompanied by a statement of the assets and liabilities of the taxpayer and an itemized statement showing all receipts and disbursements for each of the three months immediately preceding the due date of the amount to which the application relates. The application, with supporting documents, must be filed on or before the date prescribed for payment of the amount with respect to which the extension is desired with the internal revenue officer to whom the tax is to be paid. The application will be examined, and within 30 days, if possible, will be denied, granted, or tentatively granted subject to certain conditions of which the taxpayer will be notified. If an additional extension is desired, the request therefor must be made on or before the expiration of the period for which the prior extension is granted.

Payment pursuant to extension. If an extension of time for payment is granted, the amount the time for payment of which is so extended shall be paid on or before the expiration of the period of the extension without the necessity of notice and demand. The granting of an extension of the time for payment of the tax or deficiency does not relieve the taxpayer from liability for the payment of interest thereon during the period of the extension. See section 6601 and § 301.6601-1 of this chapter (Regulations on Procedure and Administration).
