§7518 Tax Incentives Relating to Merchant Marine Capital Construction Funds

Title 26 › Subtitle F — Procedure and Administration › CHAPTER 77 — MISCELLANEOUS PROVISIONS › § 7518

Last updated Sep 23, 2026|Official source

Summary

Lets owners or lessees of certain ships put qualified money into a special capital construction fund and delay tax on it, if they follow the rules. The amount they can deposit each year is limited to a sum made up of: income from operating the agreement vessels, the tax depreciation allowed for those vessels, certain sale or insurance proceeds if not already counted, and earnings from the fund. A lessee’s deposit for depreciation is reduced by any matching deposit the owner makes. Fund money must be kept where the agreement says, meet trustee rules, and be invested mostly in interest-bearing securities the Secretary approves. Up to 60 percent of the fund can be in listed domestic corporate stock if agreed, and the fund must be adjusted if stock exceeds that limit. Nonvoting preferred stock can qualify if the corporation’s common stock would qualify. The fund must keep three accounts: a capital account, a capital gain account, and an ordinary income account. Withdrawals that follow the agreement and are used to buy, build, or rebuild qualified vessels (and their barges/containers) or to pay principal on related loans are “qualified withdrawals.” Qualified withdrawals are treated first from the capital account, then the capital gain account, then the ordinary income account. If withdrawals are not for allowed purposes, they are “nonqualified” and treated first as ordinary income, then as long-term capital gain, then as capital. Special rules apply for reducing the tax basis of vessels when money comes from gain or ordinary accounts, for recapturing income on later sales, and for interest owed on some nonqualified withdrawals. If amounts stay in the fund more than 25 years, parts become nonqualified: 20% at year 26, 40% at year 27, 60% at year 28, 80% at year 29, and 100% at year 30. Transfers in a corporate reorganization or partnership continuation may be allowed without penalty under regulations.

(a)Ceiling on deposits
(1)In general
The amount deposited in a fund established under chapter 535 of title 46 of the United States Code (hereinafter in this section referred to as a “capital construction fund”) shall not exceed for any taxable year the sum of: (A)
(B)the amount allowable as a deduction under section 167 for such year with respect to the agreement vessels,
(C)if the transaction is not taken into account for purposes of subparagraph (A), the net proceeds (as defined in joint regulations) from—
(i)the sale or other disposition of any agreement vessel, or
(ii)insurance or indemnity attributable to any agreement vessel, and
(D)the receipts from the investment or reinvestment of amounts held in such fund.
(2)Limitations on deposits by lessees
In the case of a lessee, the maximum amount which may be deposited with respect to an agreement vessel by reason of paragraph (1)(B) for any period shall be reduced by any amount which, under an agreement entered into under chapter 535 of title 46, United States Code, the owner is required or permitted to deposit for such period with respect to such vessel by reason of paragraph (1)(B).
(3)Certain barges and containers included
For purposes of paragraph (1), the term “agreement vessel” includes barges and containers which are part of the complement of such vessel and which are provided for in the agreement.
(b)Requirements as to investments
(1)In general
Amounts in any capital construction fund shall be kept in the depository or depositories specified in the agreement and shall be subject to such trustee and other fiduciary requirements as may be specified by the Secretary.
(2)Limitation on fund investments
Amounts in any capital construction fund may be invested only in interest-bearing securities approved by the Secretary; except that, if such Secretary consents thereto, an agreed percentage (not in excess of 60 percent) of the assets of the fund may be invested in the stock of domestic corporations. Such stock must be currently fully listed and registered on an exchange registered with the Securities and Exchange Commission as a national securities exchange, and must be stock which would be acquired by prudent men of discretion and intelligence in such matters who are seeking a reasonable income and the preservation of their capital. If at any time the fair market value of the stock in the fund is more than the agreed percentage of the assets in the fund, any subsequent investment of amounts deposited in the fund, and any subsequent withdrawal from the fund, shall be made in such a way as to tend to restore the fund to a situation in which the fair market value of the stock does not exceed such agreed percentage.
(3)Investment in certain preferred stock permitted
For purposes of this subsection, if the common stock of a corporation meets the requirements of this subsection and if the preferred stock of such corporation would meet such requirements but for the fact that it cannot be listed and registered as required because it is nonvoting stock, such preferred stock shall be treated as meeting the requirements of this subsection.
(c)Nontaxability for deposits
(1)In general
For purposes of this title—

(B)gain from a transaction referred to in subsection (a)(1)(C) shall not be taken into account if an amount equal to the net proceeds (as defined in joint regulations) from such transaction is deposited in the fund,
(C)the earnings (including gains and losses) from the investment and reinvestment of amounts held in the fund shall not be taken into account,
(D)the earnings and profits (within the meaning of section 316) of any corporation shall be determined without regard to this section and chapter 535 of title 46, United States Code, and
(E)in applying the tax imposed by section 531 (relating to the accumulated earnings tax), amounts while held in the fund shall not be taken into account.
(2)Only qualified deposits eligible for treatment
Paragraph (1) shall apply with respect to any amount only if such amount is deposited in the fund pursuant to the agreement and not later than the time provided in joint regulations.
(d)Establishment of accounts
For purposes of this section
(1) In general

(D)ordinary income from a transaction described in subsection (a)(1)(C), and
(E)the portion of any dividend referred to in paragraph (2)(C) not taken into account under such paragraph.
(5)Capital losses only allowed to offset certain gains
Except on termination of a capital construction fund, capital losses referred to in paragraph (3)(B) or in paragraph (4)(B)(ii) shall be allowed only as an offset to gains referred to in paragraph (3)(A) or (4)(B)(i), respectively.
(e)Purposes of qualified withdrawals
(1)In general
A qualified withdrawal from the fund is one made in accordance with the terms of the agreement but only if it is for: (A)

(2)Penalty for failing to fulfill any substantial obligation
Under joint regulations, if the Secretary determines that any substantial obligation under any agreement is not being fulfilled, he may, after notice and opportunity for hearing to the person maintaining the fund, treat the entire fund or any portion thereof as an amount withdrawn from the fund in a nonqualified withdrawal.
(f)Tax treatment of qualified withdrawals
(1)Ordering rule
Any qualified withdrawal from a fund shall be treated—
(A)first as made out of the capital account,
(B)second as made out of the capital gain account, and
(C)third as made out of the ordinary income account.
(2)Adjustment to basis of vessel, etc., where withdrawal from ordinary income account
If any portion of a qualified withdrawal for a vessel, barge, or container is made out of the ordinary income account, the basis of such vessel, barge, or container shall be reduced by an amount equal to such portion.
(3)Adjustment to basis of vessel, etc., where withdrawal from capital gain account

(4)Adjustment to basis of vessels, etc., where withdrawals pay principal on debt
If any portion of a qualified withdrawal to pay the principal on any indebtedness is made out of the ordinary income account or the capital gain account, then an amount equal to the aggregate reduction which would be required by paragraphs (2) and (3) if this were a qualified withdrawal for a purpose described in such paragraphs shall be applied, in the order provided in joint regulations, to reduce the basis of vessels, barges, and containers owned by the person maintaining the fund. Any amount of a withdrawal remaining after the application of the preceding sentence shall be treated as a nonqualified withdrawal.

Subject to such conditions and requirements as may be provided in joint regulations, the preceding sentence shall not apply to a disposition where there is a redeposit in an amount determined under joint regulations which will, insofar as practicable, restore the fund to the position it was in before the withdrawal.
(g)Tax treatment of nonqualified withdrawals
(1)In general
Except as provided in subsection (h), any withdrawal from a capital construction fund which is not a qualified withdrawal shall be treated as a nonqualified withdrawal.

(3)Operating rules
For purposes of this title—
(A)any amount referred to in paragraph (2)(A) shall be included in income as an item of ordinary income for the taxable year in which the withdrawal is made,
(B)any amount referred to in paragraph (2)(B) shall be included in income for the taxable year in which the withdrawal is made as an item of gain realized during such year from the disposition of an asset held for more than 6 months, and
(C)for the period on or before the last date prescribed for payment of tax for the taxable year in which this withdrawal is made—
(i)no interest shall be payable under section 6601 and no addition to the tax shall be payable under section 6651,
(ii)interest on the amount of the additional tax attributable to any item referred to in subparagraph (A) or (B) shall be paid at the applicable rate (as defined in paragraph (4)) from the last date prescribed for payment of the tax for the taxable year for which such item was deposited in the fund, and
(iii)no interest shall be payable on amounts referred to in clauses (i) and (ii) of paragraph (2) or in the case of any nonqualified withdrawal arising from the application of the recapture provision of section 606(5) of the Merchant Marine Act, 1936, as in effect on December 31, 1969.
(4)Interest rate
For purposes of paragraph (3)(C)(ii), the applicable rate of interest for any nonqualified withdrawal shall be determined and published jointly by the Secretary of the Treasury or his delegate and the applicable Secretary and shall bear a relationship to 8 percent which the Secretaries determine under joint regulations to be comparable to the relationship which the money rates and investment yields for the calendar year immediately preceding the beginning of the taxable year bear to the money rates and investment yields for the calendar year 1970.
(5)Amount not withdrawn from fund after 25 years from deposit taxed as nonqualified withdrawal
(A)In general
The applicable percentage of any amount which remains in a capital construction fund at the close of the 26th, 27th, 28th, 29th, or 30th taxable year following the taxable year for which such amount was deposited shall be treated as a nonqualified withdrawal in accordance with the following table:
If the amount remains in the fund at the close of the— | The applicable percentage is—
26th taxable year | 20 percent
27th taxable year | 40 percent
28th taxable year | 60 percent
29th taxable year | 80 percent
30th taxable year | 100 percent.
(B)Earnings treated as deposits
The earnings of any capital construction fund for any taxable year (other than net gains) shall be treated for purposes of this paragraph as an amount deposited for such taxable year.
(C)Amounts committed treated as withdrawn
For purposes of subparagraph (A), an amount shall not be treated as remaining in a capital construction fund at the close of any taxable year to the extent there is a binding contract at the close of such year for a qualified withdrawal of such amount with respect to an identified item for which such withdrawal may be made.
(D)Authority to treat excess funds as withdrawn
If the Secretary determines that the balance in any capital construction fund exceeds the amount which is appropriate to meet the vessel construction program objectives of the person who established such fund, the amount of such excess shall be treated as a nonqualified withdrawal under subparagraph (A) unless such person develops appropriate program objectives within 3 years to dissipate such excess.
(E)Amounts in fund on January 1, 1987
For purposes of this paragraph, all amounts in a capital construction fund on January 1, 1987, shall be treated as deposited in such fund on such date.
(6)Nonqualified withdrawals taxed at highest marginal rate
(A)In general
In the case of any taxable year for which there is a nonqualified withdrawal (including any amount so treated under paragraph (5)), the tax imposed by chapter 1 shall be determined—
(i)by excluding such withdrawal from gross income, and
(ii)by increasing the tax imposed by chapter 1 by the product of the amount of such withdrawal and the highest rate of tax specified in section 1 (section 11 in the case of a corporation).
In the case of a taxpayer other than a corporation, with respect to the portion of any nonqualified withdrawal made out of the capital gain account during a taxable year to which section 1(h) applies, the rate of tax taken into account under the preceding sentence shall not exceed 20 percent.
(B)Tax benefit rule
If any portion of a nonqualified withdrawal is properly attributable to deposits (other than earnings on deposits) made by the taxpayer in any taxable year which did not reduce the taxpayer’s liability for tax under chapter 1 for any taxable year preceding the taxable year in which such withdrawal occurs—
(i)such portion shall not be taken into account under subparagraph (A), and
(ii)an amount equal to such portion shall be treated as allowed as a deduction under section 172 for the taxable year in which such withdrawal occurs.
(C)Coordination with deduction for net operating losses
Any nonqualified withdrawal excluded from gross income under subparagraph (A) shall be excluded in determining taxable income under section 172(b)(2).
(h)Certain corporate reorganizations and changes in partnerships
Under joint regulations—
(1)a transfer of a fund from one person to another person in a transaction to which section 381 applies may be treated as if such transaction did not constitute a nonqualified withdrawal, and
(2)a similar rule shall be applied in the case of a continuation of a partnership.
