Year-End Financial Planning Checklist: What Smart Investors Are Doing Before December 31

Posted November 3, 2025

The scent of pine needles (or is that peppermint?) is in the air. Your calendar is likely bursting with holiday parties, travel plans, and a seemingly endless shopping list. As the year winds down, it’s incredibly easy to get caught up in the festive flurry and put your finances on autopilot. We get it.

But before the ball drops and the confetti settles, savvy investors know that these final weeks are a golden opportunity. This isn’t just about closing the books on 2025; it’s about making strategic moves that can significantly impact your tax bill, protect your family, and set you up for a more prosperous 2026.

At Thayer Financial, we see year-end as one of the most important checkpoints in your entire financial journey. It’s a moment to review, reflect, and realign. Many of the most powerful financial opportunities are tied to the calendar—once December 31 passes, they’re gone for good.

Don’t let the end-of-year rush cost you. Here’s a practical checklist to help you make the most of these final, crucial months.

Utilizing our year end financial planning checklist can greatly enhance your financial strategy as the year comes to a close.

1. Review Your Tax Strategy (and Don’t Leave a Tip for Uncle Sam)

For many people, “taxes” are a dreaded springtime event. But thoughtful financial planning means thinking about them in the fall. Why? Because you still have time to act.

• Maximize Your Retirement Savings: This is the heavyweight champion of year-end tax moves. Every dollar you contribute to a traditional 401(k) or IRA is a dollar you don’t pay income tax on this year. For 2025, you can contribute up to $23,500 to your 401(k) (plus an extra $7,500 if you’re 50 or older). For an IRA, the limit is **$7,000** (with a $1,000 catch-up). At a minimum, make sure you’re contributing enough to get your full employer match—that’s free money!
• Harvest Your Losses: Did some of your investments in a taxable brokerage account lose value this year? While never fun, it can be a strategic opportunity. Tax-loss harvesting is the practice of selling those losing investments to “harvest” the loss. You can then use that loss to offset any capital gains you realized (like from selling a winner). And if your losses exceed your gains, you can use up to $3,000 to offset your regular income. The key rule to watch is the “wash sale rule”: you can’t buy that same (or a “substantially identical”) investment back for 30 days, or the IRS disallows the loss.
• Be Smart About Charity: If you plan on giving, be strategic. For many, “bunching” deductions—or concentrating multiple years’ worth of giving into one—can help you itemize and get a larger tax benefit. An even more powerful tool is a Donor-Advised Fund (DAF). You can contribute cash or, even better, highly appreciated stock (getting a deduction for full value and avoiding capital gains tax), and then decide which charities to grant the money to over time.

Our team works alongside your tax professional to make sure your investment strategy and tax strategy are speaking the same language.

2. Check Required Minimum Distributions (RMDs)

If you are age 73 or older, the IRS requires you to take a “Required Minimum Distribution” (RMD) from your tax-deferred retirement accounts (like Traditional IRAs and 401(k)s) every year. This is not optional. The penalty for failing to take your full RMD is a steep 25% of the amount you failed to withdraw.

The deadline is December 31. Don’t wait until the last minute, as transfers can take a few days.

For those who are 70½ or older and don’t necessarily need their RMD for living expenses, there’s a fantastic alternative: the Qualified Charitable Distribution (QCD). A QCD allows you to send up to $108,000 (for 2025) directly from your IRA to a qualified charity. This move has a powerful double benefit: the distribution counts toward your RMD, but it is not counted as taxable income. It’s a win-win for your finances and your philanthropy!

3. Assess Cash Flow and Spending

A year-end review is the perfect time to review your budget—or, as we prefer to call it, your “cash flow plan.” It’s not about judgment; it’s about data. Where did your money actually go this year?

• Did your spending align with your values and goals? If you value travel but spent more on subscriptions and dining out, this is a chance to realign.
• Check your Emergency Fund. The old rule was 3-6 months of living expenses. But after a few years of high inflation, is your “3-6 months” from 2022 still enough in 2025? Higher property taxes, insurance, and grocery bills mean your emergency fund may need a top-off. Make sure this cash is working for you in a high-yield savings account.
• Plan for 2026. Are there significant expenses on the horizon? A new roof, college tuition, a big anniversary trip, or a car purchase? By planning for these 12-18 months out, you can set aside cash systematically instead of taking a big, stressful hit all at once.

4. Update Your Protections and Insurance

Your finances aren’t just about growth; they’re about protecting what you’ve built. Your insurance policies are the defensive line for your financial plan, and they need to be checked annually.

• Home & Auto: Replacement costs for both homes and cars have skyrocketed. Is your coverage still high enough to actually rebuild your home or replace your car in 2026?
• Life Insurance: Did you have a new child, buy a new home with a bigger mortgage, or get a promotion? These life events often mean your old life insurance policy is no longer adequate.
• Umbrella Insurance: This is the most-overlooked policy by successful families. An umbrella policy provides an extra layer of liability protection (typically $1 million or more) on top of your home and auto policies. In our litigious world, it’s a non-negotiable for protecting your assets.

5. Update Your Financial Documents (and Avoid a Costly Mistake)

This one is critical. Life changes, and your legal documents must keep up. Here is one of the most important things you’ll read today: Beneficiary designations on your retirement accounts (IRAs, 401(k)s) and life insurance policies supersede your will.

We know of heartbreaking situations where an ex-spouse inherits a multi-million dollar IRA because the beneficiary form was never updated after a divorce, even though the will was. (Thankfully, this has never happened to one of our clients.)

Pull these documents now. Review the primary and contingent beneficiaries on every single account. While you’re at it, locate and review your other key estate documents:

• Will or Trust
• Durable Power of Attorney (for financial decisions if you’re incapacitated)
• Healthcare Directive (for medical decisions)

Ensure they all still reflect your wishes and protect your family.

6. Revisit Your Investment Strategy

Markets fluctuate. Even if you haven’t bought or sold a single thing, your portfolio has not stayed the same. This is called “portfolio drift.”

Imagine you started the year with a 60% stock and 40% bond allocation. But 2025 was a fantastic year for stocks, and bonds were flat. By December, without you doing anything, your portfolio might have “drifted” to 68% stocks and 32% bonds. You are now taking on significantly more risk than you intended.

Rebalancing is the disciplined process of selling some of your winners (stocks, in this case) and buying more of your underperformers (bonds) to get back to your original 60/40 target. It’s a simple, non-emotional way to “sell high and buy low” and ensure your investments stay aligned with your actual risk tolerance and long-term goals.

7. Set Your Sights on 2026

Finally, after you’ve reviewed the past, it’s time to build the future. Instead of vague “resolutions,” set concrete, actionable financial goals. Think SMART: Specific, Measurable, Achievable, Relevant, and Time-bound.

• Instead of: “Save more money.”
• Try: “Increase my 401(k) contribution by 1% by February 1.”
• Instead of: “Worry about college.”
• Try: “Open a 529 plan for my grandchild with an automatic monthly contribution of $100.”

What one thing do you want to achieve financially in 2026? Pay off a credit card? Max out your IRA? Start that 529? Write it down, and let’s build a plan to make it happen.
