(a)(1) This section applies if:

(i) An individual dies while in active service as a member of the Armed Forces of the United States, and

(ii) His death occurs while he is serving in a combat zone (as determined under section 112), or at any place as a result of wounds, disease, or injury incurred while he was serving in a combat zone.

(2) If an individuals dies as described in paragraph (a)(1), the following liabilities for tax, under subtitle A of the Internal Revenue Code of 1954 or under chapter 1 of the Internal Revenue Code of 1939, are canceled:

(i) The libaility of the deceased individual, for the last taxable year, ending on the date of his death, and for any prior taxable year ending on or after the first day he served in a combat zone in active service as a member of the U.S. Armed Forces after June 24, 1950, and

(ii) The liability of any other person to the extent the liability is attributable to an amount received after the individual's death (including income in respect of a decedent under section 691) which would have been includible in the individual's gross income for his taxable year in which the date of his death falls (determined as if he had survived).

(3) If an individual dies as described in paragraph (a)(1), there will not be assessed any amount of tax of the indvidual for taxable years preceding the years specified in paragraph (a)(2), under subtitle A of the Internal Revenue Code of 1954, chapter 1 of the Internal Revenue Code of 1939, or corresponding provisions of prior revenue laws, remaining unpaid as of the date of death. If any such unpaid tax (including interest, additions to the tax, and additional amounts) has been assessed, the assessments will be abated. If the amount of any such unpaid tax is collected after the date of death, the amount so collected will be credited or refunded as an overpayment.

(4) As to what constitutes active service as a member of the Armed Forces, service in a combat zone, and wounds, disease, or injury incurred while serving in a combat zone, see section 112. As to who are members of the Armed Forces, see section 7701(a)(15). As to the period of time within which any claim for refund must be filed, see sections 6511(a) and 7508(a)(1)(E).

(b) If such an individual and his spouse have for any such year filed a joint return, the tax abated, credited, or refunded pursuant to the provisions of section 692 for such year shall be an amount equal to that portion of the joint tax liability which is the same percentage of such joint tax liability as a tax computed upon the separate income of such individual is of the sum of the taxes computed upon the separate income of such individual and his spouse, but with respect to taxable years ending before June 24, 1950, and with respect to taxable years ending before the first day such individual served in a combat zone, as determined under section 112, the amount so abated, credited, or refunded shall not exceed the amount unpaid at the date of death. For such purpose, the separate tax of each spouse:

(1) For taxable years beginning after December 31, 1953, and ending after August 16, 1954, shall be the tax computed under subtitle A of the Internal Revenue Code of 1954 before the application of sections 31, 32, 6401(b), and 6402, but after the application of section 33, as if such spouse were required to make a separate income tax return; and

(2) For taxable years beginning before January 1, 1954, and for taxable years beginning after December 31, 1953, and ending before August 17, 1954, shall be the tax computed under chapter 1 of the Internal Revenue Code of 1939 before the application of sections 32, 35, and 322(a), but after the application of section 31, as if such spouse were required to make a separate income tax return.

(c) If such an individual and his spouse filed a joint declaration of estimated tax for the taxable year ending with the date of his death, the estimated tax paid pursuant to such declaration may be treated as the estimated tax of either such individual or his spouse, or may be divided between them, in such manner as his legal representative and such spouse may agree. Should they agree to treat such estimated tax, or any portion thereof, as the estimated tax of such individual, the estimated tax so paid shall be credited or refunded as an overpayment for the taxable year ending with the date of his death.

(d) For the purpose of determining the tax which is unpaid at the date of death, amounts deducted and withheld under chapter 24, subtitle C of the Internal Revenue Code of 1954, or under subchapter D, chapter 9 of the Internal Revenue Code of 1939 (relating to income tax withheld at source on wages), constitute payment of tax imposed under subtitle A of the Internal Revenue Code of 1954 or under chapter 1 of the Internal Revenue Code of 1939, as the case may be.

(e) This section shall have no application whatsoever with respect to the liability of an individual as a transferee of property of a taxpayer where such liability relates to the tax imposed upon the taxpayer by subtitle A of the Internal Revenue Code of 1954 or by chapter 1 of the Internal Revenue Code of 1939.
