Along with decorating the Christmas tree, lighting the Hanukkah or Kwanzaa candles and watching holiday classics like It’s a Wonderful Life, making a few last-minute moves to cut your tax bill for the year is a time-honored holiday season tradition.
With good reason: The steps you take between now and Dec. 31 can potentially slash hundreds or even thousands of dollars off what you owe Uncle Sam for 2025.
“Older taxpayers in particular have a lot to gain because they’re at a stage of life when they’re likely to have greater income and assets to protect and more pressing needs, tax-wise, in terms of retirement,” says Dan Snyder, director of personal financial planning at the American Institute of Certified Public Accountants.
Plus, the One Big Beautiful Bill Act, signed into law July 4, introduced several tax changes that have made certain moves particularly timely.
Here are seven money moves that tax experts suggest you consider tackling before ringing in the new year.
1. Bump up contributions to your workplace savings plan
IRAs can be funded right up until next year’s April 15 tax-filing deadline, but you have until only Dec. 31 to make contributions to a 401(k) or similar employer-sponsored retirement plan to reduce your 2025 tax bill and boost savings.
“Within the confines of your discretionary income, maximizing your retirement contributions is one of the most important year-end moves you can make,” Snyder says.
For 2025, taxpayers 50 and older can contribute as much as $31,000 to workplace accounts. That includes catch-up contributions of up to $7,500 on top of the regular $23,500 limit. Every dollar you contribute to a traditional tax-deferred plan reduces your taxable income by a dollar.
Conversely, contributions to a Roth 401(k) don’t reduce your taxes now, but you get the future benefit of tax-free withdrawals. “If your plan allows it, you can contribute over and above $31,000 as a nondeductible contribution and convert immediately to a Roth,” Snyder says.
If you have already maxed out contributions to a tax-deferred plan, check with your plan provider to see if you can take advantage of this “backdoor” Roth conversion before the end of the year.
2. Take your required distributions
Already retired? New rules over the past few years, courtesy of the SECURE and SECURE 2.0 acts, dictate when and how much money you need to withdraw from tax-deferred savings plans once you stop working. Congress “keeps changing the ages and the time frames, so a lot of people are confused about what they need to do,” says Julie Welch, director of taxation at Meara Welch Browne in Kansas City, Missouri.
For 2025, if you’re 73 or older you’ll need to take a required minimum distribution (RMD) based on your life expectancy by Dec. 31 or face a hefty penalty of 25 percent (reduced to 10 percent if you take the distribution within two years).
