The carryback of an NOL,

The carryback of a net section 1256 contracts loss, or

The NOL for the tax year.
-
The excess of the NOL for the year over the specified liability loss for the year to which a 10-year carryback applies, or
-
The total of the following deductions (to the extent they are taken into account in computing the NOL for the tax year):
-
Qualified GO Zone casualty loss (defined below),
-
Moving expenses paid or incurred for the employment of an individual whose main home was in the GO Zone before August 28, 2005, who was unable to remain in that home because of Hurricane Katrina, and whose main job location (after the move) is in the GO Zone,
-
Temporary housing expenses paid or incurred to house employees of the taxpayer whose main job location is in the GO Zone,

Reclamation of land,
-
Dismantling of a drilling platform,

Remediation of environmental contamination, or
-
Payment under any workers compensation act.
You must file Form 1045 within 1 year after the end of the year in which an NOL, unused credit, a net section 1256 contracts loss, or claim of right adjustment arose.

If you carry back any portion of an NOL or an unused general business credit to tax years before the 3 years preceding the 2007 tax year, you may need to use additional Forms 1045. Complete lines 1 through 9 and Schedule A on only one Form 1045. Use this Form 1045 for the earliest preceding tax years. You must sign this Form 1045, but do not need to sign the other Forms 1045.
File Form 1045 with the Internal Revenue Service Center for the place where you live as shown in the instructions for your 2007 income tax return.

Attach copies of the following, if applicable, to Form 1045 for the year of the loss or credit:
-
If you are an individual, pages 1 and 2 of your 2007 Form 1040 and Schedules A, D, and J (Form 1040), if applicable,
-
Any Form 4952, Investment Interest Expense Deduction, attached to your 2007 income tax return,
-
All Schedules K-1 you received from partnerships, S corporations, estates, or trusts that contribute to the carryback,
-
Any application for extension of time to file your 2007 income tax return,
-
All Forms 8886, Reportable Transaction Disclosure Statement, attached to your 2007 income tax return,
-
Forms 8302, Electronic Deposit of Tax Refund of $1 Million or More,
-
All other forms and schedules from which a carryback results, such as Schedule C or F (Form 1040; Form 3800, General Business Credit; Form 6781, Gains and Losses From Section 1256 Contracts and Straddles; or Form 8586, Low-Income Housing Credit, and
-
All forms or schedules for items refigured in the carryback years, such as Form 3800; Form 6251, Alternative Minimum Tax—Individuals; Form 6781; Form 8586; or Form 8844, Empowerment Zone and Renewal Community Employment Credit; or Form 8884, New York Liberty Zone Business Employee Credit.

The IRS will process your application within 90 days from the later of:
-
The date you file the complete application, or
-
The last day of the month that includes the due date (including extensions) for filing your 2007 income tax return (or, for a claim of right adjustment, the date of the overpayment under section 1341(b)(1)).
The processing of Form 1045 and the payment of the requested refund does not mean the IRS has accepted your application as correct. If the IRS later determines that the claimed deductions or credits are due to an overstatement of the value of property, negligence, disregard of rules, or substantial understatement of income tax, you may have to pay penalties. Any additional tax also will generate interest compounded daily.
The IRS may need to contact you or your authorized representative (for example, your accountant or tax return preparer) for more information so we can process your application. If you want to designate a representative for us to contact, attach a copy of your authorization to Form 1045. For this purpose, you can use Form 2848, Power of Attorney and Declaration of Representative.
Your application is not treated as a claim for credit or refund. It may be disallowed if it has material omissions or math errors that are not corrected within the 90-day period. If the application is disallowed in whole or in part, no suit challenging the disallowance can be brought in any court. But you can file a regular claim for credit or refund before the limitation period expires, as explained later under Form 1040X or Other Amended Return.
Any amount applied, credited, or refunded based on this application that the IRS later determines to be excessive may be billed as if it were due to a math or clerical error on the return.
Individuals can get a refund by filing Form 1040X, Amended U.S. Individual Income Tax Return, instead of Form 1045. An estate or trust can file an amended Form 1041, U.S. Income Tax Return for Estates and Trusts. Generally, you must file an amended return no later than 3 years after the due date of the return for the applicable tax year.
If you use Form 1040X or other amended return, follow the instructions for that return. Attach to the amended return a copy of Schedule A of Form 1045 showing the computation of the NOL and, if applicable, a copy of Schedule B of Form 1045 showing the computation of the NOL carryover. Complete a separate Form 1040X or other amended return for each year for which you request an adjustment.
The procedures for Form 1040X and Form 1045 are different. The IRS is not required to process your Form 1040X within 90 days. However, if we do not process it within 6 months from the date you file it, you can file suit in court. If the IRS disallows your claim on Form 1040X and you disagree with that determination, you must file suit no later than 2 years after the date we disallow it.
