November is prime time for year-end tax planning. There’s still plenty of opportunity to make smart financial moves that could save you money and set you up for a strong start in 2026. Whether you’re managing your household finances or running a business, a few proactive steps now can make a huge difference when tax season rolls around.
Let’s walk through some smart, doable actions to help you close out 2025 on a high note (and a low tax bill).
Why November Is the Sweet Spot for Tax Planning
The best tax planning doesn’t happen in March; it happens now.
Once the calendar flips to January 1, many opportunities are gone. 401(k) contributions, charitable donations, and expense deductions all have firm year-end deadlines.
This year also brings some notable updates to contribution limits, income thresholds, and standard deductions. Translation: What worked in 2024 might not work in 2025. Taking time to review your situation now can help you make the most of the rules before they change again.
1. Max Out Your Retirement Contributions
If you haven’t hit your contribution limit yet, now’s your moment.
For 2025, the 401(k) contribution limit rose again, which means more potential savings — and deductions. If you’re self-employed, explore a SEP IRA or Solo 401(k) before year-end.
And if you’re 50 or older, don’t forget about catch-up contributions. They not only boost your retirement cushion but also reduce your taxable income for this year.
2. Make Charitable Giving Work Harder
’Tis the season for giving — and smart giving can help your bottom line.
Charitable contributions made by December 31 can still count toward your 2025 tax deduction. Consider donating appreciated stocks instead of cash, or bunching multiple years of donations into one for a larger impact (and deduction).
Bonus idea: Set up a donor-advised fund. It lets you take an immediate deduction while planning how to distribute your gifts later. Win-win.
3. Review Your Investment Gains and Losses
If you’ve sold investments this year, now’s the time to look at your capital gains — and possibly offset them with losses.
Tax-loss harvesting can reduce your taxable income by balancing the scales between winners and losers in your portfolio.
Just keep an eye on the “wash-sale” rule: you can’t claim a loss on a stock if you buy a substantially identical one within 30 days before or after the sale.
4. Don’t Forget Required Minimum Distributions (RMDs)
If you’re age 73 or older, you must take your RMDs from traditional IRAs and employer-sponsored retirement accounts before the end of the year. Missing this deadline can mean a penalty of up to 25% of the amount not withdrawn — a mistake you definitely want to avoid.
And while you’re at it, consider whether a qualified charitable distribution (QCD) makes sense. It satisfies your RMD and supports your favorite cause at the same time — all while keeping that amount out of your taxable income.
5. Check Your Withholding and Estimated Payments
If you got an unpleasant surprise last tax season, now’s the time to fix it.
Review your paycheck withholdings or estimated quarterly payments to make sure you’re on track. Adjusting before year-end can help you avoid both a hefty bill and underpayment penalties in April.
6. Smart Moves for Business Owners
Small business owners have even more ways to trim taxable income before the clock runs out.
✅ Accelerate expenses: If it makes sense for your cash flow, prepay rent, utilities, or insurance for January to pull those deductions into this year.
✅ Defer income: If you can delay invoicing until January, you may be able to push some taxable income into 2026.
✅ Review your entity setup: The right business structure can make a huge difference in how income is taxed — something to review annually with your CPA.
✅ Upgrade equipment: Section 179 depreciation rules still allow many small businesses to write off qualifying purchases right away.
And don’t forget about retirement plans. Setting up a SEP IRA or SIMPLE 401(k) before year-end can help you and your employees save more while reducing your tax burden.
7. Arizona & Local Tax Credits Worth Remembering
If you live or do business in Arizona, there are additional credits worth exploring before December 31.
State programs allow taxpayers to support schools, foster care charities, and qualifying organizations while earning dollar-for-dollar credits on their state taxes.
These programs change periodically, so check current limits or work with your financial advisor to see which ones fit your goals.
8. Your Year-End Tax Checklist
Here’s your quick-hit list for the next few weeks:
- Review your 2025 income and projected tax bracket.
- Max out 401(k), IRA, HSA, or SEP IRA contributions.
