The Internal Revenue Service has announced income tax brackets and standard deductions for the 2024-2025 tax season.

The agency's annual inflation adjustments report revealed a 5.4% bump in income thresholds to reach each new bracket. While this bump is lower than last year's historical 7% increase, it is still more significant than times in the past when inflation was lower than the current 3.7%.

The IRS makes these changes annually, using a formula based on the consumer price index to address inflation and prevent "bracket creep," which happens when inflation pushes taxpayers into a higher bracket without any real increase in income or buying power.

There are seven federal income tax rates as set by the 2017 Tax Cuts and Job Act and they are applied progressively, meaning the more you earn, the higher percentage of taxes you pay from your income. The rates currently are set at 10%, 12%, 22%, 24%, 32%, 35% and 37%.

For 2024, the lowest rate of 10% will apply to individuals with taxable income up to $11,600 and joint filers up to $23,200. The top rate of 37% will apply to individuals making above $609,350 and married couples filing jointly earning $731,200 or more.

When is the filing deadline for 2024?

Regardless of your bracket, you must file taxes by April 15, 2024, though there are exceptions.
