General Rule
Subsection (f) of  section 1  of the Internal Revenue Code of 1986 is amended by adding at the end the following new paragraphs:
(9)
Regional cost-of-living adjustments
(A)
In general
In the case of an individual, for taxable years beginning after 2026 the rate table otherwise in effect under this section for any taxable year (determined after the application of paragraph (1)) shall be further adjusted as provided in subparagraph (B).
(B)
Method of making regional adjustment
The rate table otherwise in effect under this section with respect to any individual for any taxable year shall be adjusted as follows:
(i)
The minimum and maximum dollar amounts otherwise in effect for each rate bracket shall be multiplied by the applicable multiplier (for the calendar year in which the taxable year begins) which applies to the statistical area in which the individual’s primary place of abode during the taxable year is located.
(ii)
The rate applicable to any rate bracket (as adjusted by clause (i)) shall not be changed.
(iii)
The amount setting forth the tax shall be adjusted to the extent necessary to reflect the adjustments in the rate brackets.
 If any amount determined under clause (i) is not a multiple of $50, such amount shall be rounded to the nearest multiple of $50.
(10)
Determination of multipliers
(A)
In general
Not later than December 15 of each calendar year, the Secretary shall prescribe an applicable multiplier for each statistical area of the United States which shall apply to taxable years beginning during the succeeding calendar year.
(B)
Determination of multipliers
(i)
For each statistical area where the cost-of-living differential for any calendar year exceeds 125 percent, the applicable multiplier for such calendar year is 90 percent of such differential.
(ii)
For each statistical area where the cost-of-living differential for any calendar year exceeds 97 percent but does not exceed 125 percent, the applicable multiplier for such calendar year is 1.05.
