(a) General rules
For purposes of this subtitle—

(1) Mark to market
All property of a covered expatriate shall be treated as sold on the day before the expatriation date for its fair market value.

(2) Recognition of gain or loss
In the case of any sale under paragraph (1)—

(A) notwithstanding any other provision of this title, any gain arising from such sale shall be taken into account for the taxable year of the sale, and

(B) any loss arising from such sale shall be taken into account for the taxable year of the sale to the extent otherwise provided by this title, except that section 1091 shall not apply to any such loss.

Proper adjustment shall be made in the amount of any gain or loss subsequently realized for gain or loss taken into account under the preceding sentence, determined without regard to paragraph (3).

(3) Exclusion for certain gain

(A) In general
The amount which would (but for this paragraph) be includible in the gross income of any individual by reason of paragraph (1) shall be reduced (but not below zero) by $600,000.

(B) Adjustment for inflation

(i) In general
In the case of any taxable year beginning in a calendar year after 2008, the dollar amount in subparagraph (A) shall be increased by an amount equal to—

(I) such dollar amount, multiplied by

(II) the cost-of-living adjustment determined under section 1(f)(3) for the calendar year in which the taxable year begins, by substituting "calendar year 2007" for "calendar year 2016" in subparagraph (A)(ii) thereof.

(ii) Rounding
If any amount as adjusted under clause (i) is not a multiple of $1,000, such amount shall be rounded to the nearest multiple of $1,000.

(b) Election to defer tax

(1) In general
If the taxpayer elects the application of this subsection with respect to any property treated as sold by reason of subsection (a), the time for payment of the additional tax attributable to such property shall be extended until the due date of the return for the taxable year in which such property is disposed of (or, in the case of property disposed of in a transaction in which gain is not recognized in whole or in part, until such other date as the Secretary may prescribe).

(2) Determination of tax with respect to property
For purposes of paragraph (1), the additional tax attributable to any property is an amount which bears the same ratio to the additional tax imposed by this chapter for the taxable year solely by reason of subsection (a) as the gain taken into account under subsection (a) with respect to such property bears to the total gain taken into account under subsection (a) with respect to all property to which subsection (a) applies.

(3) Termination of extension
The due date for payment of tax may not be extended under this subsection later than the due date for the return of tax imposed by this chapter for the taxable year which includes the date of death of the expatriate (or, if earlier, the time that the security provided with respect to the property fails to meet the requirements of paragraph (4), unless the taxpayer corrects such failure within the time specified by the Secretary).

(4) Security

(A) In general
No election may be made under paragraph (1) with respect to any property unless adequate security is provided with respect to such property.

(B) Adequate security
For purposes of subparagraph (A), security with respect to any property shall be treated as adequate security if—

(i) it is a bond which is furnished to, and accepted by, the Secretary, which is conditioned on the payment of tax (and interest thereon), and which meets the requirements of section 6325, or

(ii) it is another form of security for such payment (including letters of credit) that meets such requirements as the Secretary may prescribe.

(5) Waiver of certain rights
No election may be made under paragraph (1) unless the taxpayer makes an irrevocable waiver of any right under any treaty of the United States which would preclude assessment or collection of any tax imposed by reason of this section.

(6) Elections
An election under paragraph (1) shall only apply to property described in the election and, once made, is irrevocable.

(7) Interest
For purposes of section 6601, the last date for the payment of tax shall be determined without regard to the election under this subsection.

(c) Exception for certain property
Subsection (a) shall not apply to—

(1) any deferred compensation item (as defined in subsection (d)(4)),

(2) any specified tax deferred account (as defined in subsection (e)(2)), and

(3) any interest in a nongrantor trust (as defined in subsection (f)(3)).
