The scariest part of Halloween shouldn’t be your tax bill. As 2025 winds down, now is the time to take control of your finances and make sure you don’t get spooked by the IRS come spring. Year-end tax planning doesn’t have to feel like a haunted house—it’s simply about making smart moves before December 31st.

Here’s a simple, easy-to-follow checklist to keep financial nightmares away and help you start the new year with confidence.

1. Review Your Withholding & Estimated Taxes

Don’t let an unexpected tax bill scare you this spring. Check your W-4 and estimated payments to make sure you’re on track. If you’ve had major life changes in 2025—like a new job, marriage, or home purchase—adjusting your withholding now can prevent a nasty surprise later.

Pro Tip: Sign up for our Tax Strategy Guide to get an in-depth estimate of your potential refund and discover tax-saving opportunities before the year ends. This service helps you plan proactively and confidently for both personal and business finances.

2. Max Out Retirement Contributions

Think of your retirement account like a protective charm. Contributing to your 401(k), IRA, or SEP IRA before year-end not only grows your nest egg but also reduces your taxable income. Contribution limits have increased slightly for 2025, so double-check how much room you still have to save.

Pro Tip: Work with Peters Financial to see if you can increase contributions before year-end or optimize your retirement strategy for maximum tax savings. They can help you save smarter while reducing your taxable income.

3. Harvest Tax Losses (and Gains) Wisely

Investments that underperformed? Selling them before December 31st can offset capital gains and reduce your taxable income. Just remember the “wash sale” rule, the IRS doesn’t like it when you sell and repurchase the same stock too quickly.

Pro Tip: Review your portfolio with a tax professional to strategically harvest losses and gains. Timing your sales carefully can make a significant difference in your tax liability.

4. Use Up Flexible Spending Accounts (FSAs)

Don’t let your hard-earned FSA money disappear like a ghost. Medical checkups, prescriptions, or even new glasses are eligible expenses. If your plan allows, some funds may roll over—but it’s better to use them than lose them.

Pro Tip: Check your FSA balance now and schedule any qualifying expenses before year-end. Consider family medical visits or elective prescriptions that can be covered by your FSA.

5. Plan Charitable Contributions

Giving back can be a treat for others, and a tax benefit for you. Donations to qualified charities are deductible, so make sure you keep receipts and proper documentation. Bonus: donating appreciated stock can give you an even bigger tax advantage.

Pro Tip: Review your charitable giving plan and document every donation carefully. Consider donating appreciated assets for double tax benefits, avoiding capital gains while still getting a deduction.

6. Defer or Accelerate Income When Possible

If you’re self-employed or a small business owner, timing is everything. Deferring income into 2026 or accelerating deductions into 2025 can help you manage your tax bracket and keep more money in your pocket.

Pro Tip: Work with a tax professional to run “what-if” scenarios. Small adjustments in timing can have a large impact on your total tax bill.

7. Double-Check Deductions & Credits

Don’t leave money on the table. Education credits, child tax credits, energy-efficient home upgrades, and business expenses can all reduce your tax bill. Make sure you’ve documented everything before the clock strikes midnight on December 31st.

Pro Tip: Make a checklist of all potential deductions and credits, then review it with a professional. Missing even one credit could cost you hundreds or thousands of dollars.

Tax planning doesn’t have to be scary. Following this checklist can help you minimize taxable income, maximize deductions, and avoid penalties, making April 2026 far less frightening.
