Year-End Tax Planning Checklist for Tampa Bay Retirees

Year-end tax planning isn't something that happens in January while doing your 2024 return—it happens in October, November, and early December, while you still have time to act. Many retirees leave money on the table simply because they wait too long. Here are 15 actionable tax strategies worth reviewing before year-end.

First, review your RMD situation if you're age 73 or older. The deadline for RMDs is December 31st. If you haven't taken this year's distribution from your IRA or 401(k), make sure you do. Missing an RMD triggers a 25% penalty (recently reduced from 50%) on the amount not withdrawn. For a $50,000 RMD, that's $12,500 in penalties. No exceptions, no second chances. If you're over 73, this is non-negotiable.

Consider Qualified Charitable Distributions (QCDs) if you're 70.5 or older. QCDs allow you to transfer up to $100,000 per year directly from your IRA to a qualified charity without including it in your taxable income. This is particularly valuable if you itemize deductions or are close to IRMAA thresholds for Medicare. Unlike charitable deductions, QCDs directly reduce your AGI. For a retiree in the 22% bracket, a $10,000 QCD saves $2,200 in federal tax alone.

Harvest tax losses strategically. If you have securities trading at a loss in your taxable accounts, selling them now locks in the loss. Harvested losses offset capital gains dollar-for-dollar, and excess losses (up to $3,000) offset ordinary income. The key rule: don't buy the same or "substantially identical" security within 30 days before or after the sale. Buy a similar (but different) replacement, and you've harvested the loss cleanly. This works beautifully in down market years.

Implement Roth conversion strategies. If you're planning conversions, sooner is better—October and November give you two months to process the transaction and understand the impact before year-end. If you want to adjust or undo a conversion, the deadline to "recharacterize" (return the funds) is October 15 of the following year. Converting in October still gives you time to evaluate and make changes in the next calendar year if needed.

Bunch charitable giving into a single year using a Donor-Advised Fund (DAF). If you give $5,000 to charity in each of the next four years, you might not be able to itemize deductions—you'd be stuck with the standard deduction. But if you bunch those $20,000 into a single year via a DAF, you exceed the standard deduction and capture significant itemized deductions. Afterward, you direct the DAF to make annual distributions to your charities. This increases your deduction in the bunching year while still supporting your causes over time.

Manage estimated quarterly tax payments if you have business income or significant non-wage income. The fourth-quarter estimated payment is due January 15, 2026. Calculate whether you're under-withheld or likely to be. Over-withholding now (via January 15 payment) could mean a refund later. Under-withholding could mean penalties. For self-employed retirees, this is crucial.

Consider municipal bonds for tax-free income. Municipal bond interest is generally free from federal income tax, and if you buy bonds issued in your home state, they're often state-tax-free too. For Florida residents, this tax-free income doesn't push you into IRMAA or increase your Social Security taxation the way taxable income does. Rebalancing into munis in late October or November still provides a full year of tax-free interest if held into 2026.

Review your Form W-4 if you're still working. If you over-withheld taxes throughout 2025, adjusting your W-4 now could reduce future withholding and improve your cash flow in the final months of the year. Conversely, if you under-withheld, increasing withholding could avoid penalties. For retirees with part-time income or consulting work, this matters significantly.

Batch large deductions strategically. If you're planning home repairs, charitable contributions, medical expenses, or other deductible items, clustering them into 2025 might allow you to exceed the standard deduction threshold and itemize. Deferring some into 2026 does the opposite. Understanding your deduction capacity helps you time large expenses optimally.

Gift appreciated securities instead of cash to charities. If you own a stock that's appreciated significantly, donating the shares themselves (rather than selling and donating cash) lets you avoid the capital gains tax entirely while capturing the fair-market-value deduction. This is particularly relevant for long-term holdings and highly appreciated positions.

Maximize retirement plan contributions if still working. For 2025, you can contribute $24,000 to a 401(k) ($35,000 if age 50+) and $7,000 to an IRA ($8,000 if age 50+). These contributions reduce your taxable income dollar-for-dollar. If you own a business, a Solo 401(k) or SEP-IRA allows even larger contributions—potentially $70,000+. Contributions must be made by December 31st (or by the business filing deadline if self-employed).

Review your taxable account positions for loss-harvesting opportunities. Beyond just selling losers, consider your gains. If you have a $30,000 gain in one position and a $25,000 loss in another, harvesting the loss against the gain locks in a $5,000 net gain at 15% capital gains rate instead of realizing a $30,000 gain at 15% and a $25,000 loss separately. Coordination matters.

Coordinate with charitable remainder trusts or other advanced gifting vehicles if you've planned them. These transactions have year-end deadlines. A Charitable Remainder Trust (CRT) set up by December 31st allows you to fund it with appreciated assets, receive a charitable deduction, and generate income streams over time. Planning these transactions in November ensures you hit the deadline.
