Section 302.1-4 - Computation of taxes(a)Detail of employees of the Internal Revenue Service. The Commissioner will detail for the assistance of the Attorney General such employees of the Internal Revenue Service as may be necessary to make the computations under the regulations in this part promptly and accurately.(b)Relationship of Attorney General and former owner. In the computation of tax liability under the regulations in this part, except as otherwise provided herein, the vesting of property shall not be considered as affecting the ownership thereof; and any act of the Attorney General in respect of such property (including the collection or operation thereof and any investment, sale, or other disposition and any payment or other expenditure) shall be considered as the act of the owner. Nevertheless, except as otherwise provided in the Act or the regulations in this part, insofar as taxes are incident to the vested property during the period of vesting, they shall be payable by the Attorney General, except that to the extent of the value of any of the property returned to the former owner the latter shall be liable for such tax not paid by the Attorney General. While tax incident to nonvested property is collectible out of both vested and nonvested property, the nonvested property will be regarded as the primary source of collection of such tax. In determining the amount of liability to be paid out of property not vested by the Attorney General a computation shall be made covering the taxpayer's full period of liability, but without regard to the vested property, or the income received by, or the operations of, the Attorney General. The amount so computed shall be first asserted against and collected so far as practicable from the taxpayer or out of his property which is not vested. Such part of the total tax liability as is not paid by the taxpayer or collected out of property not vested shall be asserted against the vested property. See § 302.1-5 , relating to payment of taxes, and § 302.1-7 , relating to claims for credit or refund.(c)Laws applicable to computations. Except as otherwise specifically provided in the regulations in this part, the computation under the regulations in this part of any internal revenue tax liability shall be in accordance with the internal revenue laws and regulations applicable thereto, including all amendments of such laws or regulations enacted or promulgated prior to determination of the tax.(d)Periods for which computations made. The amount of income, declared value excess profits, excess profits, capital stock, employment, and excise taxes under the internal revenue laws will be computed for each taxable year or period during all or part of which property is vested prior to the return of the property. In the case of a return of property prior to computation of tax, see § 302.1-3 . Where vesting occurs during a taxable year or taxable period, any return filed or computation made covering vested or nonvested property should nevertheless be for the entire year or period. See paragraph (b) of this section. Unless facts are available indicating a liability for taxes for a taxable year or period occurring wholly prior or subsequent to the period of vesting of the property by the Attorney General, the computations under the regulations in this part, both tentative and final, will be made only in respect of years and periods during all or part of which the property is held by the Attorney General.(e)Tentative computation. In order that the return of property or other appropriate action may not be delayed until the amount of taxes payable is finally computed and paid, a tentative computation of such amount will be made in every case, unless there are circumstances appearing to make such action inappropriate. Such circumstances would include (1) return of the property in accordance with § 302.1-3 ,(2) notice to the Commissioner by the person to whom the property is returnable or by the Attorney General that such person or the Attorney General, as the case may be, prefers that the return of the property be postponed until the amount of such taxes can be finally computed or(3) belief on the part of the Commissioner that a final computation will not unduly delay the return of, or other appropriate action with respect to, the property. In making any such tentative computation of income, profits, or estate tax, the gross income or the gross estate, as the case may be, as shown by the records of the Attorney General (excluding therefrom items exempt from taxation) shall be considered as the taxable or net income or taxable or net estate, respectively, unless a tax return has been filed or facts are available upon which a more accurate computation can be made. In any case in which a duly authorized officer or employee of the Internal Revenue Service has otherwise computed the amount of taxes payable in respect of any period, such computation will be accepted as a tentative computation, unless the facts clearly indicate that a more accurate computation can be made.(f)Final computation - (1)General. A final computation of the amount of taxes payable by the person to whom property is returnable, or out of property to be returned, will be made as soon as practicable in every case. In any case in which the amount shown by a tentative computation has been paid, refund or credit of any amount paid in excess of the amount properly due will be made in accordance with the final computation, even though a claim therefor has not been filed, if the period of limitation applicable to the filing of such claim has not expired. However, if it is desired to protect the right to any credit or refund determined to be due, a claim for credit or refund should be filed. The sufficiency of any such claim in respect of any amount paid in accordance with a tentative computation under the regulations in this part will not be questioned solely because facts upon which a more accurate computation could be made are not available or cannot be established at the time such claim is filed. Any such claim in respect of an amount paid in accordance with a final computation must, however, clearly set forth in detail under penalties of perjury all the facts relied upon in support of the claim and must conform to the regulations applicable to an ordinary claim for refund or credit. See § 302.1-7 relating to claims for credit or refunds.(2)Information required -(i)Income and profit taxes. The following information submitted under penalties of perjury by or for the taxpayer is necessary in each case for a final computation, for each taxable year for which the computation is to be made: (a) All income (other than income received by the Attorney General) from sources within the United States, or if no such income has been received, then a statement to that effect, except that in the case of a citizen or resident of the United States, income from sources without as well as within the United States must be shown.(b) If a return of such income has been made, then the following data in respect of such return: (1) The taxable year for which the return was made and the tax (whether income, declared value excess profits, or excess profits tax) paid;(2) The name of the taxpayer for whom the return was made;(3) The name of the agent or other person (if any) by whom such return was made;(4) The office of the district director in which such return was filed.(c) Such other facts as may be required, from time to time, by the Commissioner.(ii)Other taxes. Except as otherwise provided in subdivision (i) of this subparagraph, in order to make a final computation of the amount of any internal revenue tax payable by return in any case, the usual return should be filed, together with the supporting documents required by the regulations pertaining to the tax.(g)Tax returns -(1)General. In many cases allowance of deductions and credits is contingent upon the making of a return in accordance with the applicable internal revenue law. The submission of evidence relative to income or profits tax in accordance with subdivisions (a) and (c) of paragraph (f)(2)(i) of this section will be considered as the making of the return required by any such law, only(i) for any taxable period, ending on or before December 31, 1946, during all or part of which all or part of the property of the taxpayer was held by the Attorney General, or(ii) for any taxable period ending within one year from the date of the first return to the taxpayer of any part of the property held by the Attorney General, whichever period ends later. In all other cases a return will be required in accordance with the applicable internal revenue law and regulations. In the case of returns where property is vested during a taxable year or period, see paragraph (d) of this section.(2)Estates and trusts. In the case of estates and trusts the fiduciaries shall file returns, including information returns as required by section 147 of the Internal Revenue Code of 1939 or section 6041 of the Internal Revenue Code of 1954.(3)Income tax forms to be used - (i)General. In the case of taxpayers engaged in trade or business in the United States Forms 1040B and 1120, as may be appropriate, shall be used. Where the taxpayer is not engaged in trade or business in the United States, Form M797 may be used in lieu of Forms 1040NB, 1040NB--a, and 1120NB.(ii)Definition. When used in subdivision (i) of this subparagraph, the term "engaged in trade or business in the United States" includes the managing and renting of real estate in the United States by an agent of the Attorney General or of the former owner duly authorized to execute rental agreements and to pay all taxes and charges incident to the repair and maintenance of such property, but does not include the mere renting or leasing of property under agreement requiring the lessee or occupant to pay taxes and to make repairs or improvements.
