Limitation based on modified adjusted gross income
(A) In general
(A)In general#
If the modified adjusted gross income of the taxpayer for the taxable year exceeds $40,000 ($60,000 in the case of a joint return), the amount which would (but for this paragraph) be excludable from gross income under subsection (a) shall be reduced (but not below zero) by the amount which bears the same ratio to the amount which would be so excludable as such excess bears to $15,000 ($30,000 in the case of a joint return).
(B)Inflation adjustment#
In the case of any taxable year beginning in a calendar year after 1990, the $40,000 and $60,000 amounts contained in subparagraph (A) shall be increased by an amount equal to—
(i) such dollar amount, multiplied by
(ii) the cost-of-living adjustment under section 1(f)(3) for the calendar year in which the taxable year begins, determined by substituting “calendar year 1989” for “calendar year 2016” in subparagraph (A)(ii) thereof.
(B)(i)#
such dollar amount, multiplied by
(B)(ii)#
the cost-of-living adjustment under section 1(f)(3) for the calendar year in which the taxable year begins, determined by substituting “calendar year 1989” for “calendar year 2016” in subparagraph (A)(ii) thereof.
(C)Rounding#
If any amount as adjusted under subparagraph (B) is not a multiple of $50, such amount shall be rounded to the nearest multiple of $50 (or if such amount is a multiple of $25, such amount shall be rounded to the next highest multiple of $50).
