Tax Moves to Make Now to Maximize Your 2025 Refund

‍

Tax planning isn’t just something to scramble for once a year—it’s a continuous process that can save you money and increase your refund when you file your 2025 taxes in early 2026. Whether you’re a salaried employee, self-employed, investor, or homeowner, making smart tax moves during the 2025 tax year is key to maximizing your refund.

‍

In this guide, we’ll walk through important steps to take in 2025 that can reduce your taxable income and boost your refund next year. Plus, we’ll explore a real-life example of how a family man, James, uses these strategies to his advantage.

‍

‍

Why Early Tax Planning Matters

‍

Planning your taxes early allows you to adjust your income, deductions, and credits throughout the year rather than scrambling at tax time. This approach gives you more control over your refund or tax liability and helps avoid surprises when you file in 2026 for the 2025 tax year.

‍

When you start tax planning early:

‍

• You can make informed decisions about withholding or estimated payments
  
  
• You have time to maximize contributions to retirement and savings accounts
  
  
• You can strategically time deductible expenses and charitable donations
  
  
• You ensure you meet deadlines for tax-advantaged accounts
  
  

‍

Essential Tax Moves to Make in 2025 to Maximize Your Refund

‍

1. Review and Adjust Your Tax Withholding

‍

Many people either withhold too little or too much tax from their paychecks. Underwithholding can lead to owing taxes at filing time, while overwithholding means you’re essentially giving the government an interest-free loan all year.

‍

Start 2025 by using the IRS Tax Withholding Estimator to check if your current withholding is appropriate. If not, submit a new Form W-4 to your employer to increase or decrease the amount withheld.

‍

Adjusting your withholding keeps your tax payments on track throughout 2025, avoiding surprises and potentially maximizing your refund when you file in 2026.

‍

‍

2. Maximize Retirement Contributions for 2025

‍

Contributions to tax-advantaged retirement accounts are one of the most effective ways to reduce your taxable income for 2025.

‍

401(k) or 403(b):

‍

For 2025, employees can contribute up to $23,500. If you're age 50 or older, you can make an additional $7,500 catch-up contribution, bringing the total to $31,000. These contributions are made pre-tax, which reduces your taxable income.

‍

For individuals ages 60 to 63, the SECURE 2.0 Act introduces a higher catch-up contribution limit of $11,250 starting in 2025, although this must be made as a Roth (after-tax) contribution if your income exceeds $145,000.

‍

If you’re in a 403(b) plan and have at least 15 years of service with the same employer, you may qualify for an additional catch-up contribution of up to $3,000 per year, with a $15,000 lifetime limit. This is in addition to the age-based catch-up.
‍

‍

Traditional IRA:

‍

You can contribute up to $7,000 to a Traditional IRA for 2025. If you're age 50 or older, you can contribute an additional $1,000, for a total of $8,000.
 

‍

You have until the tax filing deadline in April 2026 to make your 2025 contribution.

‍

Deductibility depends on your income and whether you or your spouse are covered by a workplace retirement plan. (More on deduction limits)

‍

‍

SEP IRA or Solo 401(k):

‍

If you’re self-employed or own a small business:

‍

• You can contribute up to 25% of your net earnings from self-employment, up to a maximum of $69,000 in 2025, using a SEP IRA or Solo 401(k).
  
  

• Solo 401(k) plans also allow an employee deferral of up to $23,500, plus a $7,500 catch-up if age 50 or older, in addition to employer profit-sharing contributions—potentially reaching the same $69,000 (or $76,500 if 50+).
  
  

‍

These plans are powerful tools for maximizing retirement savings and tax deductions for the self-employed.

‍

Make sure contributions are made within the 2025 calendar year or, for IRAs, by the tax filing deadline to qualify for deductions on your 2025 return.

‍

‍

3. Use Health Savings Accounts (HSAs) to Save Taxes

‍

If you have a high-deductible health plan (HDHP), contributing to an HSA in 2025 can reduce your taxable income, grow tax-free, and allow tax-free withdrawals for qualified medical expenses.

‍

✅ 2025 HSA Contribution Limits

‍

According to IRS Revenue Procedure 2024-25:

‍

• Self-only coverage: $4,300
  
  
• Family coverage: $8,550
  
  
• Catch-up contribution (for individuals aged 55 or older): $1,000

‍

‍

🩺 HDHP Requirements for 2025

‍

To be eligible to contribute to an HSA, you must be enrolled in a high-deductible health plan (HDHP). For 2025, the IRS defines an HDHP as a plan with:

‍

📅 Minimum annual deductible:

- Self-only coverage: $1,650

- Family coverage: $3,300
‍

‍

📅‍ Maximum annual out-of-pocket expenses:

- Self-only coverage: $8,300

- Family coverage: $16,600

‍

These figures are detailed in IRS Publication 969. IRS+2IRS+2IRS+2

‍

📅 Contribution Deadline

Unlike IRAs, HSA contributions for a given tax year must be made by December 31 of that year. Therefore, to benefit from the 2025 tax advantages, ensure your HSA contributions are completed by December 31, 2025.

‍

‍

4. Harvest Investment Losses

‍

Selling investments at a loss — also known as tax-loss harvesting — can help offset capital gains and reduce your taxable income.

‍

• If your capital losses exceed your capital gains, you can deduct up to $3,000 (or $1,500 if married filing separately) against ordinary income in 2025.
  
  
• Any remaining losses can be carried forward indefinitely to offset future gains or income.
  
  

This strategy can be especially useful at year-end. Review your brokerage or taxable investment accounts in 2025 to identify underperforming or unwanted assets that could be sold to realize a tax loss.

5. Claim All Eligible Tax Credits

‍

Tax credits directly reduce your tax bill dollar-for-dollar and can substantially increase your refund. Some key tax credits to consider for 2025 include:

‍

• Earned Income Tax Credit (EITC) — for low to moderate-income workers
  
  
• Child Tax Credit (CTC) — for parents with qualifying children
  
  
• American Opportunity Credit and Lifetime Learning Credit — for qualified education expenses
  
  
• Child and Dependent Care Credit — for expenses related to child or dependent care
  
  

Make sure to keep thorough documentation throughout 2025 to prove your eligibility when filing your tax return

‍

6. Donate to Charity Strategically

‍

Charitable donations can be tax-deductible if you itemize your deductions on your tax return.

‍

• Consider donating appreciated stock instead of cash — this can help you avoid paying capital gains tax on the appreciation, while still allowing you to deduct the full fair market value of the donated stock.
  
  

• If you usually take the standard deduction, think about “bunching” multiple years’ worth of donations into 2025. This strategy can push your total deductions above the standard deduction threshold, enabling you to itemize and maximize your tax benefits.

‍

‍

7. Prepay Deductible Expenses if Possible

‍

You may be able to increase your 2025 tax deductions by prepaying certain deductible expenses that are due in early 2026, such as:

‍

• Property taxes
  
  
• Mortgage interest payments
  
  

‍

Before making any prepayments, check with your lender or a tax advisor to ensure these payments will be eligible for deduction in the 2025 tax year. Proper timing and documentation are key to maximizing your benefit.

‍

‍

‍

8. Utilize Flexible Spending Accounts (FSAs)

‍

If your employer offers Healthcare or Dependent Care FSAs, contribute the maximum allowed amount for 2025 to pay for eligible expenses with pre-tax dollars. This reduces your taxable income.

‍

• Keep detailed receipts and records of all eligible expenses to claim reimbursements and be prepared in case of an IRS audit.

‍

‍

9. Track Business Expenses Meticulously

‍

If you’re self-employed or own a business, maintain detailed records of all expenses incurred in 2025, including:

‍

• Office supplies
  
  
• Travel and meals (note that meal expenses are generally limited to 50%)
  
  
• Home office deductions
  
  
• Equipment purchases
  
  

Accurate bookkeeping helps maximize your deductions, reducing your taxable income and the risk of audit issues.

10. Choose the Right Filing Status and Dependents

‍

Ensure you claim the filing status that provides the greatest tax benefit (for example, Head of Household if you qualify).

‍

Also, list all qualifying dependents to maximize your eligibility for valuable credits and deductions like the Child Tax Credit or Earned Income Tax Credit.

🤵 Scenario: How James, a Mid-Level Manager, Maximizes His 2025 Tax Refund

‍

James is a mid-level manager earning $95,000 annually. He and his spouse have two young children and plan to buy their first home in late 2025. Here’s how James approaches tax planning throughout 2025:

‍

• Adjusts withholding: Since his spouse reduces work hours to care for their children, James submits a new Form W-4 early in 2025 to reflect their lower combined income and avoid overpaying taxes during the year.
  
  

• Maximizes 401(k) contributions: Both James and his spouse contribute the maximum allowed to their employer-sponsored retirement plans, totaling $46,000 in 2025 pre-tax contributions, which lowers their taxable income.
  
  

• Funds a 529 College Savings Plan: James contributes $10,000 toward their children’s education savings. Depending on their state, this may qualify them for state tax credits or deductions.
  
  

• Utilizes FSAs: They contribute the maximum allowed to their healthcare and dependent care FSAs, covering daycare and medical expenses with pre-tax dollars.
  
  

• Pre-pays mortgage interest: To increase deductible expenses for 2025, they prepay their January 2026 mortgage interest payment in December 2025.
  
  

• Bundles charitable donations: James and his spouse time their donations to exceed the standard deduction threshold in 2025, allowing them to itemize deductions and benefit from larger tax savings.
  
  

‍

Thanks to these smart moves, James and his family reduce their taxable income, qualify for multiple tax credits, and maximize deductions, resulting in a significantly larger refund when they file their 2025 taxes in early 2026.
