# §507. Termination of private foundation status

- (a) **General rule—** Except as provided in [subsection (b)](#b), the status of any [organization](/usc/26/414.md?p=m-6-A) as a [private foundation](/usc/26/509.md?p=a) shall be terminated only if—
  - (1) such [organization](/usc/26/414.md?p=m-6-A) notifies the Secretary (at such time and in such manner as the Secretary may by regulations prescribe) of its intent to accomplish such termination, or
  - (2)
    - (A) with respect to such [organization](/usc/26/414.md?p=m-6-A), there have been either willful repeated acts (or failures to act), or a willful and flagrant act (or failure to act), giving rise to liability for tax under [chapter 42](/usc/26/chstD/ch42.md), and
    - (B) the Secretary notifies such [organization](/usc/26/414.md?p=m-6-A) that, by reason of [subparagraph (A)](#a-2-A), such [organization](/usc/26/414.md?p=m-6-A) is liable for the tax imposed by [subsection (c)](#c),

  and either such [organization](/usc/26/414.md?p=m-6-A) pays the tax imposed by [subsection (c)](#c) (or any portion not abated under [subsection (g)](#g)) or the entire amount of such tax is abated under [subsection (g)](#g).

- (b) **Special rules—**
  - (1) **Transfer to, or operation as, public charity—** The status as a [private foundation](/usc/26/509.md?p=a) of any [organization](/usc/26/414.md?p=m-6-A), with respect to which there have not been either willful repeated acts (or failures to act) or a willful and flagrant act (or failure to act) giving rise to liability for tax under [chapter 42](/usc/26/chstD/ch42.md), shall be terminated if—
    - (A) such [organization](/usc/26/414.md?p=m-6-A) distributes all of its net assets to one or more [organizations](/usc/26/414.md?p=m-6-A) described in [section 170(b)(1)(A)](/usc/26/170.md?p=b-1-A) (other than in clauses (vii) and (viii)) each of which has been in existence and so described for a continuous period of at least 60 calendar months immediately preceding such distribution, or
    - (B)
      - (i) such [organization](/usc/26/414.md?p=m-6-A) meets the requirements of paragraph [(1)](/usc/26/509.md?p=a-1), [(2)](/usc/26/509.md?p=a-2), or [(3)](/usc/26/509.md?p=a-3) of section 509(a) by the end of the 12-month period beginning with its first taxable year which begins after December 31, 1969, or for a continuous period of 60 calendar months beginning with the first day of any taxable year which begins after December 31, 1969,
      - (ii) such [organization](/usc/26/414.md?p=m-6-A) notifies the Secretary (in such manner as the Secretary may by regulations prescribe) before the commencement of such 12-month or 60-month period (or before the 90th day after the day on which regulations first prescribed under this subsection become final) that it is terminating its [private foundation](/usc/26/509.md?p=a) status, and
      - (iii) such [organization](/usc/26/414.md?p=m-6-A) establishes to the satisfaction of the Secretary (in such manner as the Secretary may by regulations prescribe) immediately after the expiration of such 12-month or 60-month period that such [organization](/usc/26/414.md?p=m-6-A) has complied with [clause (i)](#b-1-B-i).

    If an [organization](/usc/26/414.md?p=m-6-A) gives notice under [subparagraph (B)(ii)](#b-1-B-ii) of the commencement of a 60-month period and such [organization](/usc/26/414.md?p=m-6-A) fails to meet the requirements of paragraph [(1)](/usc/26/509.md?p=a-1), [(2)](/usc/26/509.md?p=a-2), or [(3)](/usc/26/509.md?p=a-3) of section 509(a) for the entire 60-month period, this part and [chapter 42](/usc/26/chstD/ch42.md) shall not apply to such [organization](/usc/26/414.md?p=m-6-A) for any taxable year within such 60-month period for which it does meet such requirements.

  - (2) **Transferee foundations—** For purposes of this part, in the case of a transfer of assets of any [private foundation](/usc/26/509.md?p=a) to another [private foundation](/usc/26/509.md?p=a) pursuant to any liquidation, merger, redemption, recapitalization, or other adjustment, [organization](/usc/26/414.md?p=m-6-A), or [reorganization](/usc/26/368.md?p=a-1), the transferee foundation shall not be treated as a newly created [organization](/usc/26/414.md?p=m-6-A).
- (c) **Imposition of tax—** There is hereby imposed on each [organization](/usc/26/414.md?p=m-6-A) which is referred to in [subsection (a)](#a) a tax equal to the lower of—
  - (1) the amount which the [private foundation](/usc/26/509.md?p=a) substantiates by adequate records or other corroborating evidence as the aggregate tax benefit resulting from the [section 501(c)(3)](/usc/26/501.md?p=c-3) status of such foundation, or
  - (2) the [value](/usc/26/851.md?p=c-4) of the net assets of such foundation.
- (d) **Aggregate tax benefit—**
  - (1) **In general—** For purposes of [subsection (c)](#c), the aggregate tax benefit resulting from the [section 501(c)(3)](/usc/26/501.md?p=c-3) status of any [private foundation](/usc/26/509.md?p=a) is the sum of—
    - (A) the aggregate increases in tax under chapters [1](/usc/26/chstA/ch1.md), [11](/usc/26/chstB/ch11.md), and [12](/usc/26/chstB/ch12.md) (or the corresponding provisions of prior law) which would have been imposed with respect to all substantial contributors to the foundation if deductions for all contributions made by such contributors to the foundation after February 28, 1913, had been disallowed, and
    - (B) the aggregate increases in tax under [chapter 1](/usc/26/chstA/ch1.md) (or the corresponding provisions of prior law) which would have been imposed with respect to the income of the [private foundation](/usc/26/509.md?p=a) for taxable years beginning after December 31, 1912, if (i) it had not been exempt from tax under [section 501(a)](/usc/26/501.md?p=a) (or the corresponding provisions of prior law), and (ii) in the case of a trust, deductions under [section 642(c)](/usc/26/642.md?p=c) (or the corresponding provisions of prior law) had been limited to 20 percent of the [taxable income](/usc/26/63.md?p=a) of the trust (computed without the benefit of [section 642(c)](/usc/26/642.md?p=c) but with the benefit of [section 170(b)(1)(A)](/usc/26/170.md?p=b-1-A)), and
    - (C) [interest](/usc/26/856.md?p=f-1) on the increases in tax determined under subparagraphs [(A)](#d-1-A) and [(B)](#d-1-B) from the first date on which each such increase would have been due and payable to the date on which the [organization](/usc/26/414.md?p=m-6-A) ceases to be a [private foundation](/usc/26/509.md?p=a).
  - (2) **Substantial contributor—**
    - (A) **Definition—** For purposes of [paragraph (1)](#d-1), the term “substantial contributor” means any person who contributed or bequeathed an aggregate amount of more than $5,000 to the [private foundation](/usc/26/509.md?p=a), if such amount is more than 2 percent of the total contributions and bequests received by the foundation before the close of the taxable year of the foundation in which the contribution or bequest is received by the foundation from such person. In the case of a trust, the term “substantial contributor” also means the creator of the trust.
    - (B) **Special rules—** For purposes of [subparagraph (A)](#d-2-A)—
      - (i) each contribution or bequest shall be valued at fair market [value](/usc/26/851.md?p=c-4) on the date it was received,
      - (ii) in the case of a foundation which is in existence on October 9, 1969, all contributions and bequests received on or before such date shall be treated (except for purposes of [clause (i)](#d-2-B-i)) as if received on such date,
      - (iii) an individual shall be treated as making all contributions and bequests made by his spouse, and
      - (iv) any person who is a substantial contributor on any date shall remain a substantial contributor for all subsequent periods.
    - (C) **Person ceases to be substantial contributor in certain cases—**
      - (i) **In general—** A person shall cease to be treated as a substantial contributor with respect to any [private foundation](/usc/26/509.md?p=a) as of the close of any taxable year of such foundation if—
        - (I) during the 10-year period ending at the close of such taxable year such person (and all [related persons](/usc/26/414.md?p=n-6-A)) have not made any contribution to such [private foundation](/usc/26/509.md?p=a),
        - (II) at no time during such 10-year period was such person (or any [related person](/usc/26/864.md?p=d-4)) a foundation manager of such [private foundation](/usc/26/509.md?p=a), and
        - (III) the aggregate contributions made by such person (and [related persons](/usc/26/414.md?p=n-6-A)) are determined by the Secretary to be insignificant when compared to the aggregate amount of contributions to such foundation by one other person.

      For purposes of subclause (III), appreciation on contributions while held by the foundation shall be taken into account.

      - (ii) **Related person—** For purposes of [clause (i)](#d-2-C-i), the term “[related person](/usc/26/864.md?p=d-4)” means, with respect to any person, any other person who would be a disqualified person (within the meaning of [section 4946](/usc/26/4946.md)) by reason of his relationship to such person. In the case of a contributor which is a corporation, the term also includes any officer or director of such corporation.
  - (3) **Regulations—** For purposes of this section, the [determination](/usc/26/1313.md?p=a) as to whether and to what extent there would have been any increase in tax shall be made in accordance with regulations prescribed by the Secretary.
- (e) **Value of assets—** For purposes of [subsection (c)](#c), the [value](/usc/26/851.md?p=c-4) of the net assets shall be determined at whichever time such [value](/usc/26/851.md?p=c-4) is higher: (1) the first day on which action is taken by the [organization](/usc/26/414.md?p=m-6-A) which culminates in its ceasing to be a [private foundation](/usc/26/509.md?p=a), or (2) the date on which it ceases to be a [private foundation](/usc/26/509.md?p=a).
- (f) **Liability in case of transfers of assets from private foundation—** For purposes of determining liability for the tax imposed by [subsection (c)](#c) in the case of assets transferred by the [private foundation](/usc/26/509.md?p=a), such tax shall be deemed to have been imposed on the first day on which action is taken by the [organization](/usc/26/414.md?p=m-6-A) which culminates in its ceasing to be a [private foundation](/usc/26/509.md?p=a).
- (g) **Abatement of taxes—** The Secretary may abate the unpaid portion of the assessment of any tax imposed by [subsection (c)](#c), or any liability in respect thereof, if—
  - (1) the [private foundation](/usc/26/509.md?p=a) distributes all of its net assets to one or more [organizations](/usc/26/414.md?p=m-6-A) described in [section 170(b)(1)(A)](/usc/26/170.md?p=b-1-A) (other than in clauses (vii) and (viii)) each of which has been in existence and so described for a continuous period of at least 60 calendar months, or
  - (2) following the notification prescribed in [section 6104(c)](/usc/26/6104.md?p=c) to the appropriate State officer, such State officer within one year notifies the Secretary, in such manner as the Secretary may by regulations prescribe, that corrective action has been initiated pursuant to State law to insure that the assets of such [private foundation](/usc/26/509.md?p=a) are preserved for such charitable or other purposes specified in [section 501(c)(3)](/usc/26/501.md?p=c-3) as may be ordered or approved by a court of competent jurisdiction, and upon completion of the corrective action, the Secretary receives certification from the appropriate State officer that such action has resulted in such preservation of assets.
