We’re in early December, which means you have a few weeks left to make meaningful adjustments to your 2025 tax situation. This is the perfect time to estimate your taxable income for the year and see where you land in the tax brackets. A little planning now can save you thousands in April.
If you’re not weaving tax planning into your overall retirement and investment strategy, you’re most likely leaving money on the table. And I’m not talking about the returns that show up on your 401(k) statement. Having a 401(k) or IRA doesn’t mean you have a retirement plan. A proper financial plan is multifaceted—it incorporates investment strategy, tax optimization, estate planning, and risk management. If you think financial planning is just about choosing between a handful of stocks or an index fund, you’re missing the bigger picture.
With that in mind, here are five year-end tax planning areas to focus on. These are the low-hanging fruit—the opportunities that show up in my client base year after year. This isn’t an exhaustive list, and not everything will apply to your situation, but chances are at least a few of these will be worth exploring. As always, consult your tax planning professionals before implementing any of these strategies. This outline is for educational purposes only.
1. Tax-Loss Harvesting
Tax-loss harvesting involves selling investments at a loss within your brokerage account to offset realized gains elsewhere in your portfolio. This can minimize your overall capital gains tax bill. Nobody invests hoping for losses, but they’re inevitable. Historical analysis shows us that markets rise about 70% of the time, but the average intra-year drop is around 14% according to JP Morgan’s Guide to the Markets research. Taking advantage of these dips can create tax benefits.
But just because you sell, it doesn’t mean you’re trying to sit out of the market. You sell the losing position and immediately buy something similar but substantially different to maintain your market exposure. Just watch out for the wash sale rule: in summary, if you buy the same or a substantially identical security within 30 days before or after the sale, the IRS won’t allow you to claim the loss.
Any losses you don’t use this year can be carried forward indefinitely, and you can deduct up to $3,000 annually against ordinary income.
2. Tax-Gain Harvesting
Tax-loss harvesting gets all the attention, but tax-gain harvesting deserves more. Sometimes it makes sense to intentionally realize gains or pull income into the current year. Why would anyone want to increase their taxable income? Let me show you with an example:
For long-term capital gains, a couple filing jointly in 2025 can have up to $96,700 in taxable income and pay 0% in capital gains tax. Remember, taxable income is what’s left after deductions. For a couple both age 65 in 2025, the deduction math looks like this:
- Standard deduction: $31,500
- Age 65+ additional deduction: $3,200 ($1,600 per)
- New senior bonus deduction: $12,000 ($6,000 per, subject to income limitations)
- Total deductions: $46,700
This means a couple could have adjusted gross income of $143,400 and still be in the 0% capital gains bracket. That’s over $10,000 per month in spending—pretty reasonable for many couples in retirement.
Let’s say you add up all your income and you’re only at $110,000. Does it make sense to realize some capital gains? It’s at least something to explore. You’ll increase taxable income, but if done correctly, you won’t pay a dime in additional capital gains tax. This strategy works particularly well in the early years of retirement if you’re delaying Social Security or IRA distributions and spending from after-tax brokerage accounts.
And just like tax-loss harvesting, the goal is not to sell your positions and sit out of the market. Remember the wash sale rule mentioned above only applies to losses. If you like an investment that’s appreciated, you can sell it, realize the gain tax-free, and immediately buy it back without missing out on future growth.
3. Income and Expense Timing
You can’t always control when income arrives or expenses hit, but when you can, timing matters.
For example, the One Big Beautiful Bill passed earlier in 2025 increased the state and local tax (SALT) deduction limit to $40,000 (up from $10,000) for 2025, subject to income limits. If you’re in a high-tax state and you haven’t maximized this benefit for the current year, you might consider prepaying your 2026 first-quarter taxes if your jurisdiction allows it. This lowers your 2025 taxable income and lets you maximize the deduction again in 2026. This benefit only runs through 2028, so use it while you can. You’ll need to itemize to claim this, but with the OBBB changes, it’s worth running the numbers even if you typically take the standard deduction.
On the income side, that new senior bonus deduction might make it worthwhile to pull some income into 2025 to take full advantage of your available deductions. Or consider a Roth conversion to fill up lower tax brackets in low-income years. A Roth conversion involves moving money from a traditional IRA to a Roth IRA, paying taxes now at today’s rates, and enjoying tax-free growth and withdrawals later.
4. Charitable Giving Strategies
If you’re charitably inclined, Qualified Charitable Distributions (QCDs) are powerful. Once you’re 70½, you can donate directly from your IRA to charity. The distribution doesn’t count as taxable income, and it satisfies your required minimum distribution if you’re over 73.
Another charitable giving strategy involves donating appreciated investments from your brokerage account directly to a Donor Advised Fund. The charity gets the full value, you avoid capital gains tax on the appreciation, and you increase the cost basis in your brokerage account. Two birds, one stone.
One more item to know—starting in 2026, there’s a new 0.5% AGI floor and a 35% cap for top-bracket donors. For example, if you have $400,000 in income, you’d only be able to deduct amounts given over $2,000. And if you’re in the highest tax bracket, your deduction is capped at 35 cents per dollar donated. Cash-gift deductions continue to be capped at 60% of AGI; that limit has not changed.
This creates an opportunity to accelerate giving in 2025 before these restrictions kick in.
5. Retirement Plan Contributions
The basics still matter. Maximize your 401(k) employee deferrals before December 31st. Health Savings Accounts and 529 education funds are also great year-end moves. While 529 contributions don’t provide a federal tax deduction, most states offer a state income tax benefit—check your specific state rules.
One exception to the December 31st deadline: if you have an Individual 401(k) and it’s the plan’s first year, you have until the tax filing deadline to establish and fund it for the prior year. This can be useful if you find yourself with extra cash after the new year.
Planning ahead makes all the difference. These strategies won’t all apply to everyone, but most lawyers approaching or in retirement will benefit from at least a few of them.
