A year-end tax planning checklist covers Q4 actions including maximizing retirement contributions, reviewing tax-loss harvesting, evaluating Roth conversions, charitable giving, and RMDs.

Year-End Tax Planning Checklist

1 / 7

Maximize Retirement Contributions

  • Confirm you are on track to maximize 401(k) contributions, the 2025 limit is $23,500 ($31,000 if age 50+).
  • IRA contributions (traditional or Roth) can be made until the tax filing deadline, but planning ahead is advisable.
  • If your employer offers a mega backdoor Roth option, consider maximizing after-tax contributions before year-end.
  • HSA contributions (if eligible) also have year-end deadlines, the 2025 limit is $4,300 individual / $8,550 family.

Maximize Retirement Contributions

  • Confirm you are on track to maximize 401(k) contributions, the 2025 limit is $23,500 ($31,000 if age 50+).
  • IRA contributions (traditional or Roth) can be made until the tax filing deadline, but planning ahead is advisable.

  • HSA contributions (if eligible) also have year-end deadlines, the 2025 limit is $4,300 individual / $8,550 family.

Review Tax-Loss Harvesting Opportunities

  • Identify positions with unrealized losses that could be sold to offset realized capital gains from the year.
  • Net capital losses exceeding gains may offset up to $3,000 of ordinary income per year, with the remainder carrying forward.
  • Be mindful of the 30-day wash sale rule when repurchasing substantially identical securities.
  • Tax-loss harvesting is generally only available in taxable accounts, not retirement accounts.

Evaluate Roth Conversion Opportunities

  • Low-income years or years with unusually large deductions may present favorable Roth conversion windows.
  • Converting traditional IRA or 401(k) assets to Roth triggers ordinary income tax but provides tax-free growth going forward.
  • Model the conversion amount carefully to avoid pushing into a higher marginal tax bracket or triggering IRMAA surcharges.
  • Roth conversions are irrevocable under current law, consult a tax advisor before proceeding.

Charitable Giving and Bunching

  • Consider bunching charitable contributions using a donor-advised fund if you alternate between itemizing and taking the standard deduction.
  • Donating appreciated securities held over one year may allow you to avoid capital gains tax and claim a fair market value deduction.
  • Qualified charitable distributions (QCDs) from IRAs are available for taxpayers age 70½ and older.
  • Ensure all charitable contributions are completed and documented by December 31.

Required Minimum Distributions (RMDs)

  • If you are age 73 or older (under current SECURE Act rules), ensure your RMD is taken by December 31.
  • First-year RMD recipients may defer until April 1 of the following year, but this doubles up distributions in that year.
  • Failing to take a required RMD may result in a 25% excise tax on the amount not distributed (reduced from 50% under SECURE 2.0).
  • Consider whether a qualified charitable distribution can satisfy part or all of your RMD obligation.

Capital Gains and Estimated Tax Review

  • Review realized capital gains and losses for the year to assess your net tax position before year-end.
  • If you have significant gains, consider whether additional tax-loss harvesting or charitable giving could offset the liability.
  • Verify that estimated tax payments or withholding are sufficient to avoid underpayment penalties.
  • Capital gains harvesting (intentionally recognizing gains in low-income years) may be appropriate in some situations.

Key Takeaways

  • Year-end is the last opportunity to take many tax-reducing actions for the current tax year.
  • Prioritize items with hard December 31 deadlines: 401(k) contributions, RMDs, tax-loss harvesting, and charitable gifts.
  • Model your projected tax liability before making decisions about Roth conversions or capital gains recognition.
  • Work with a tax advisor to identify the strategies most relevant to your specific financial situation.
