2024 IRS Tax Changes: What You Need to Know


The new year brings new tax brackets, deductions, and limits that will impact your 2024 federal income tax return. While 2023 did not see major federal tax reform legislation, the IRS has adjusted ranges for tax brackets, standard deductions, retirement savings contributions and more to account for inflation. These 2024 IRS tax code tweaks affect taxpayers across income levels and will change how much you owe or your refund amount. Understanding the latest IRS adjustments will allow you to update your withholding and take advantage of any new breaks. A financial advisor can help you stay up to date on the latest in tax rules and regulations.

Tax Change Basics

The five major 2024 tax changes cover income tax brackets, the standard deduction, retirement contribution limits, the gift tax exclusion and phase-out levels for Individual Retirement Account (IRA) deductions, Roth IRAs and the Saver’s Credit. This annual inflation adjustment ensures that taxpayers aren’t bumped into higher brackets due to cost-of-living increases rather than pay raises.

While many adjustments are relatively minor, even small tweaks can add up to substantial savings or higher bills. For example, an upper-middle class couple could bank over $1,000 more by making the most of increased 401(k) contributions and shifting IRA deductibility planning.
