10 Smart Summer Tax Moves to Shrink Your 2025 Bill Before It’s Too Late
Summer isn’t just for cookouts and vacations.
It’s actually the perfect window—calm enough, early enough—to make smart tax moves before the year starts slipping away. You don’t have to overhaul your finances or spend hours in spreadsheets. But if you wait until the fall (or worse, winter), the choices shrink fast.
This is about small, practical steps that still pack a punch. Whether you’re a W-2 employee, a 1099 contractor, or running an S Corp, here’s what you can do this summer to lower your 2025 tax bill while you still have time.
1. Check Your Withholding or Estimated Payments
If you owed a surprise tax bill in April, now’s the time to adjust.
Seriously, don’t wait. Mid-year is when changes still have time to matter without overcorrecting.
-
W-2? Revisit your W-4 and check if you’re withholding enough.
-
1099 or business owner? Run a new projection and align your estimated tax payments.
Too many people forget about this and scramble in Q4. You don’t need that stress.
2. Convert Some of Your IRA to a Roth—Early
Why now? Because timing matters.
Doing a Roth conversion during the summer lets you spread out the income and maybe even reduce the tax impact by planning it over multiple months. The earlier you start, the more options you have.
Also: fewer surprises. Waiting until December leaves no wiggle room.
If you’re thinking long-term and expect your tax rate to go up later, paying some tax now to avoid more tax later can be worth it.
Already dealing with RMDs? You might benefit even more.
3. Boost Your HSA Contributions
Health Savings Accounts (HSAs) are still underutilized—and still one of the best tax shelters.
Limits for 2025:
-
$4,150 for individuals
-
$8,300 for families
-
+$1,000 if you’re 55+
The trick is to not spend your HSA funds right away. Pay out-of-pocket now if you can afford it, and let the account grow tax-free. You can reimburse yourself later, even years later.
Triple-tax-advantaged. No other account works quite like it.
4. Bunch Your Donations This Year (If You Itemize)
Most people take the standard deduction—because it’s pretty high now.
But if you donate to charity and your itemized deductions hover just below the standard threshold, consider bunching this year’s and next year’s giving into 2025. That way, you might actually get a tax break for being generous.
Not sure where to give yet? Open a Donor-Advised Fund (DAF) this summer. Donate now, take the deduction, and distribute the money later.
5. Review Your Business Numbers Now (Not in December)
Running a business or side hustle?
Summer is a great time to step back and look at your profit and expenses so far this year.
-
Are your quarterly taxes on track?
-
Should you shift more income to payroll (S Corp owners)?
-
Are you missing deductions?
This is also when you might want to reevaluate your entity type. If you’re still a sole proprietor, the S Corp route might make more sense now than ever.
Also take a fresh look at your business travel deductions—summer trips could double as strategy sessions if done right.
6. Treat Your Side Hustle Like a Business
Let’s say you sell art online or tutor on weekends. If that income is just going into your personal account with no expense tracking, you’re missing out.
Open a separate business bank account. Start documenting your expenses. Consider a business structure if income is picking up.
And if you’re not sure it’s worth the trouble—see how physicians are doing it to save on taxes and build wealth outside of clinical work.
7. Scan for Market Losses (Tax-Loss Harvesting)
Nobody likes market dips, but if you’ve got unrealized losses in your taxable accounts, you might be able to turn those into tax savings.
Sell underperforming assets to lock in losses. You can use those to offset capital gains and reduce taxable income—up to $3,000 against ordinary income.
Then? Reinvest in something similar (just not “substantially identical” or the IRS will disallow the loss—wash-sale rule).

8. Catch Up or Front-Load Retirement Contributions
Summer is halftime. Not too late to make progress.
Max out:
-
Traditional or Roth 401(k): $23,000 (plus $7,500 if 50+)
-
Traditional or Roth IRA: $7,000 (plus $1,000 if 50+)
If you’re self-employed? Look into Solo 401(k)s or SEP IRAs. They come with higher contribution limits and more control.

9. Consider 529 Contributions and State Tax Benefits
Planning ahead for college?
Many states give you a state income tax deduction for 529 plan contributions. That’s an easy summer win.
And if you have cash on hand, there’s a 5-year front-loading rule that allows gifts of up to $90,000 per child ($180,000 per couple) without triggering gift tax.
You don’t need to go that big, obviously. But even a few thousand dollars in a 529 now could be worth both tax breaks and future tuition relief.
10. Meet With Your Tax Advisor—Before Everyone Else Does
By fall, it gets crowded. Your tax advisor’s time is spread thin. Your options shrink.
A summer planning meeting lets you:
-
Adjust projections early
-
Make strategic moves with plenty of time left in the year
-
Avoid rushing through decisions in December
Even just an hour could save you more than any spreadsheet tweak.
Some topics worth asking about:
FAQ: Summer Tax Moves and 2025 Planning
Why plan taxes during summer instead of year-end?
Because you still have time to adjust course. Waiting until the fall or winter limits your choices and forces rushed decisions.
Are these strategies only for high-income people?
Not at all. Anyone can adjust withholding, contribute to HSAs or IRAs, or review spending and deductions. The earlier you start, the better your outcome—no matter your income.
What’s one quick thing I can do today?
Check your withholding or estimated taxes. Seriously, that alone can save you stress next April.
Is it too early to do a Roth conversion?
Not if you want flexibility. Spreading the tax impact over more months lets you fine-tune how much you convert and potentially avoid higher tax brackets.
Do I need a tax advisor for this?
You don’t need one—but the right advisor can spot missed deductions, map out long-term plans, and help you avoid costly missteps. Summer’s a great time to get that help while things are still calm.
