The big picture: The Internal Revenue Service made a few other changes to account for inflation, including raising contribution limits for tax-deferred retirement plans in 2023 and a 3-cent increase to the mileage rate.
- The higher limits to 401(k) plans can help people save more for retirement, which in many cases will help lower their income tax.
- The new tax adjustments apply to tax returns filed in 2024, but the IRS also changed the 2023 tax withholding tables, which determine how much money employers should withhold from employee wages in paychecks for federal taxes.
