Cost of Living Tax Cut Act

The Cost of Living Tax Cut Act allows individual income tax brackets to automatically adjust based on the specific cost of living in a taxpayer's region starting in the 2027 tax year. The bill requires the Treasury to calculate multipliers for different statistical areas using a new cost-of-living index, which will increase tax thresholds for areas where living costs are significantly higher than the national average. This mechanism ensures that the tax rates themselves remain unchanged while the dollar amounts defining each bracket rise to reflect local economic conditions. The law applies to individuals living in metropolitan or non-metropolitan areas and takes effect for taxable years beginning after December 31, 2026.
