§ 20.2001-1 Valuation of adjusted taxable gifts and section 2701(d) taxable events. ( a ) *Adjusted taxable gifts made prior to August 6, 1997.* For purposes of determining the value of adjusted taxable gifts as defined in section 2001(b), if the gift was made prior to August 6, 1997, the value of the gift may be adjusted at any time, even if the time within which a gift tax may be assessed has expired under section 6501. This paragraph (a) also applies to adjustments involving issues other than valuation for gifts made prior to August 6, 1997.
( b ) *Adjusted taxable gifts and section 2701(d) taxable events occurring after August 5, 1997.* For purposes of determining the amount of adjusted taxable gifts as defined in section 2001(b), if, under section 6501, the time has expired within which a gift tax may be assessed under chapter 12 of the Internal Revenue Code (or under corresponding provisions of prior laws) with respect to a gift made after August 5, 1997, or with respect to an increase in taxable gifts required under section 2701(d) and § 25.2701-4 of this chapter, then the amount of the taxable gift will be the amount as finally determined for gift tax purposes under chapter 12 of the Internal Revenue Code and the amount of the taxable gift may not thereafter be adjusted. The rule of this paragraph (b) applies to adjustments involving all issues relating to the gift, including valuation issues and legal issues involving the interpretation of the gift tax law.
( c ) *Finally determined.* For purposes of paragraph (b) of this section, the amount of a taxable gift as finally determined for gift tax purposes is— ( 1 ) The amount of the taxable gift as shown on a gift tax return, or on a statement attached to the return, if the Internal Revenue Service does not contest such amount before the time has expired under section 6501 within which gift taxes may be assessed;
( 2 ) The amount as specified by the Internal Revenue Service before the time has expired under section 6501 within which gift taxes may be assessed on the gift, if such specified amount is not timely contested by the taxpayer;
( 3 ) The amount as finally determined by a court of competent jurisdiction; or
( 4 ) The amount as determined pursuant to a settlement agreement entered into between the taxpayer and the Internal Revenue Service.
( d ) *Definitions.* For purposes of paragraph (b) of this section, the amount is finally determined by a court of competent jurisdiction when the court enters a final decision, judgment, decree or other order with respect to the amount of the taxable gift that is not subject to appeal. See, for example, section 7481 regarding the finality of a decision by the U.S. Tax Court. Also, for purposes of paragraph (b) of this section, a settlement agreement means any agreement entered into by the Internal Revenue Service and the taxpayer that is binding on both. The term includes a closing agreement under section 7121, a compromise under section 7122, and an agreement entered into in settlement of litigation involving the amount of the taxable gift.
( e ) *Expiration of period of assessment.* For purposes of determining if the time has expired within which a tax may be assessed under chapter 12 of the Internal Revenue Code, see § 301.6501(c)-1(e) and (f) of this chapter.
( f ) *Effective dates.* Paragraph (a) of this section applies to transfers of property by gift made prior to August 6, 1997, if the estate tax return for the donor/decedent's estate is filed after December 3, 1999. Paragraphs (b) through (e) of this section apply to transfers of property by gift made after August 5, 1997, if the gift tax return for the calendar period in which the gift is made is filed after December 3, 1999.
