Start Q3 Strong: 5 Mid-Year Tax Planning Moves to Make Now

The halfway point of the year is the perfect time to take a financial pulse check. If you’ve been putting off tax planning until year-end—or worse, tax season—you may be missing key opportunities to save money, reduce stress, and avoid penalties. At Vincere Tax, we believe tax strategy isn’t a one-time event—it’s a year-round mindset.

With Q3 underway, here are five impactful mid-year tax planning moves to make now to ensure your 2025 tax year ends with fewer surprises and more money in your pocket.

1. Reassess Your Withholding and Estimated Payments

If you’ve had any financial changes this year—new job, raise, freelance side gig, or significant investment income—it’s time to revisit your tax withholding or estimated payments.

Why It Matters in 2025:

The IRS updated income tax brackets, standard deductions, and thresholds for 2025. If you’re not aligned with these changes, you may be under- or overpaying taxes.

Standard Deduction for 2025:

  • Single: $15,000
  • Married Filing Jointly: $30,000
  • Head of Household: $22,500

💡 Pro Tip:

Use the IRS Tax Withholding Estimator to determine if you’re on track. For those with self-employment or gig income, ensure your quarterly estimated payments are aligned with your current income trajectory.

📌 Example:
Emily started earning $2,000/month from consulting in addition to her day job. By recalculating her estimated payments mid-year, she avoided a surprise tax bill and penalty come April.

📆 2025 Estimated Tax Payment Deadlines
  • Q1: April 15, 2025
  • Q2: June 16, 2025
  • Q3: September 15, 2025
  • Q4: January 15, 2026

2. Maximize Retirement Contributions Before It’s Too Late

One of the easiest ways to reduce your taxable income is by contributing to retirement accounts—and the earlier in the year you do it, the more your money grows.

🔢 2025 Contribution Limits:

💡 Pro Tip:

Don’t wait until December. Spreading your contributions across the remaining months gives your investments more time to grow and lowers your risk of missing the deadline.

📌 Example:
Mark, 52, realized in July he was behind on his 401(k). By increasing his payroll contributions for the rest of the year, he reached the full $31,000 limit (standard + catch-up) by December.

🔁 Your state retirement rules may vary. Always double-check local limits and tax treatment with your advisor.

3. Harvest Tax Losses (and Gains) While You Can

Tax-loss harvesting isn’t just for December. Mid-year is a smart time to review your portfolio and offset capital gains with any underperforming assets.

Why It Matters in 2025:

You can use up to $3,000 of net capital losses to offset ordinary income each year. Losses beyond that carry forward to future years. And with continued market volatility, smart timing can yield major savings.

(IRS Publication 550 – Investment Income and Expenses)

💡 Pro Tip:

Avoid the “wash sale rule,” which disallows losses if you buy a “substantially identical” asset within 30 days. Work with a tax pro or financial advisor to strategize tax-efficient rebalancing.

📌 Example:
In July, Anna sold a tech ETF at a $5,000 loss to offset earlier gains from real estate investments. She immediately reinvested in a similar but not identical ETF to stay invested, preserving her market position while reducing 2025 taxes.

4. Review Your Flexible Spending and Health Accounts

If you’re enrolled in an FSA or HSA, now’s the time to check balances and ensure you’re optimizing these powerful tax-advantaged tools.

🏥 2025 Limits:

  • Health FSA (Medical): $3,300
  • Dependent Care FSA: $5,000 per household ($2,500 MFS)

  • Health Savings Account (HSA):
  • Individual: $4,300
  • Family: $8,550
  • Catch-Up (55+): $1,000

(IRS Publication 969 – HSAs and Other Tax-Favored Health Plans)

💡 Pro Tip:

FSAs are use-it-or-lose-it for most employers. Schedule dental work, vision care, or other qualified expenses now to avoid forfeiting funds. HSAs, on the other hand, don’t expire and can be a powerful retirement asset.

📌 Example:
Carlos realized in August he had $1,400 left in his FSA. He booked a dental cleaning and new glasses before year-end, using funds he would’ve otherwise lost.

5. Take Advantage of Charitable Giving Strategies

Charitable donations are about more than goodwill—they can significantly reduce your tax burden, especially if you itemize deductions.

💰 2025 Tip:

The standard deduction remains high, so many taxpayers don’t itemize. But with smart planning, you may still benefit from charitable giving:

  • Bunch donations: Combine multiple years of giving into one year to exceed the standard deduction threshold.
  • Donate appreciated assets: Give stocks instead of cash to avoid capital gains tax and get a deduction for the full fair market value.
  • Use Qualified Charitable Distributions (QCDs): If you’re 70½ or older, donate up to $100,000 directly from your IRA tax-free.

(IRS Topic No. 506 – Charitable Contributions)

💡 Pro Tip:

If you’re close to the itemization threshold, track all donations carefully and consider using a Donor-Advised Fund (DAF) to control timing and deductions.

📌 Example:
The Thompsons donated $20,000 in appreciated stock to a DAF in 2025. This allowed them to itemize for the first time in years while avoiding capital gains tax on the stock’s growth.

📋 Mid-Year Tax Planning Checklist

Here’s a quick reference guide to what you should review now:

  • Maximize your retirement contributions: 401(k), IRA, HSA, and FSA limits are updated for 2025.
  • Harvest capital losses or gains to manage your 2025 tax exposure.
  • Use or schedule your FSA funds before year-end to avoid losing unused amounts.
  • Plan charitable contributions strategically—consider bunching, QCDs, or donating appreciated assets.

Each step can help reduce your tax liability and avoid year-end stress.

🔍 Why Mid-Year Tax Planning Works

Too many people treat taxes as a once-a-year scramble. By planning in Q3, you unlock:

  • More Time to adjust and respond
  • Bigger Savings through compounding and optimization
  • Less Stress during tax season
  • Fewer Surprises from underpayments or overlooked deductions

Frequently Asked Questions

1. What if I didn’t make estimated payments earlier this year?

Yes—HSA contributions are pre-tax, grow tax-free, and can be withdrawn tax-free for qualified medical expenses.

4. Can I change my 401(k) contributions mid-year?

Yes, most employers allow adjustments anytime. Check your HR portal or payroll system and maximize savings before year-end.

5. When is the next estimated tax payment due?

For 2025, Q3 estimated payments are due September 15, 2025. Avoid interest and penalties by submitting on time.
