9 End-of-Year Tax Moves That Could Save You $2,000+

As the year winds down, it's a good time to make tax decisions that can meaningfully lower your bill. A few strategic moves can reduce your taxable income, boost deductions, and position you for a smoother filing season. Since many tax breaks may only be available before the tax year ends on December 31st, waiting could cost you. If you want to prepare yourself financially for the year ahead, these smart tax moves are worth a closer look.

Below are nine end-of-year strategies that could save you $2,000 or more.

Max out your 401(k) contributions

Potential savings: $500–$1,500

For 2025, the IRS increased the 401(k) contribution limit to $23,500, with an additional $7,500 catch-up contribution for workers age 50 or older. A special higher catch-up applies for ages 60 to 63, allowing $11,250 instead of $7,500. IRA limits remain $7,000, with a $1,000 catch-up.

Every dollar you contribute reduces taxable income dollar-for-dollar. For example, someone in the 22% bracket who adds $2,000 could save $440 in taxes. Review your payroll contributions, calculate remaining room, and ask HR to increase your rate for the final pay periods of the year.

Harvest investment losses

Potential savings: $300–$800

Tax-loss harvesting allows you to sell losing investments and use those losses to offset capital gains. You can deduct up to $3,000 of excess losses against ordinary income each year. For example, if you have $5,000 in gains and $8,000 in losses, you could eliminate all gains and deduct $3,000 against your income.

Evaluate your brokerage accounts for unrealized losses and sell positions before year-end. Avoid the wash sale rule, which bars repurchasing the same security within 30 days. If you want to maintain market exposure, buy a similar — but not identical — investment. Keep in mind that trades must settle by December 31st.

Contribute to a Health Savings Account (HSA)

Potential savings: $400–$1,000

For 2025, the HSA contribution limits are $4,300 for self-only coverage and $8,550 for family coverage, plus a catch-up contribution for individuals age 55 or older who are not enrolled in Medicare.

HSAs offer a powerful triple tax advantage — deductible contributions, tax-free investment growth, and tax-free withdrawals for qualified medical costs. If you have a high-deductible health plan, review your current contributions and add more before the deadline. Employer contributions count toward your limit, and individual contributions can be made until April 15th.

Bunch charitable deductions

Potential savings: $200–$600

If you don't normally exceed the standard deduction, grouping multiple years of donations into one year may allow you to itemize. For 2025, the standard deduction is:

• Single / Married filing separately: $15,750
• Married filing jointly: $31,500
• Head of household: $23,625

Consider giving two or three years' worth at once or using a donor-advised fund for flexibility. If you donate appreciated stock instead of cash, you could avoid capital gains taxes while still deducting the full fair market value. For example, instead of giving $3,000 annually for 3 years, give $9,000 this year. Be sure all contributions are made by December 31st and collect written acknowledgments for gifts of $250 or more.

Accelerate business expenses

Potential savings: $300–$800

Business owners and freelancers can pull forward expenses to lower this year's taxable income. Section 179 allows expensing up to $2.5 million of qualified equipment purchases, with a phase-out starting at $4 million. Bonus depreciation remains available on certain assets.

You can also prepay business software subscriptions, professional dues, or training expenses. If you use a home office, you may deduct $5 per square foot up to 300 square feet. Make purchases before December 31st and keep receipts documenting business use.

Convert a traditional IRA to a Roth IRA

Potential long-term savings: $1,000 or more

A Roth conversion can make sense in a low-income year, since you'll pay taxes now but enjoy tax-free withdrawals in retirement. However, converting too much could bump you into a higher bracket, so consider a partial conversion to stay within your current rate.

Calculate available bracket space, ensure you have funds outside your IRA to pay the tax, and complete the conversion by December 31st. For example, a $10,000 conversion in the 22% bracket costs $2,200 now but could save much more when tax rates rise, or your investments grow.

Prepay state and local taxes

Potential savings: $200–$500

The SALT deduction is normally limited to $10,000, but under the One Big Beautiful Bill, the cap increases to $40,000 for 2025 to 2029.

If you haven't maxed out your SALT deductions, consider paying property taxes due early next year before December 31st. Prepaying your fourth-quarter estimated state income tax payment may also increase your deduction. Be careful not to prepay more than one year, and remember that the alternative minimum tax may reduce this benefit for high-income individuals.

Maximize Flexible Spending Account (FSA) funds

Potential savings: $150–$400

FSAs operate under a use-or-lose rule unless your employer offers a grace period or small rollover amount. For 2025, the FSA limit is $3,300 for health expenses and $5,000 for dependent care.

Check your balance and spend remaining funds on eligible healthcare or dependent care expenses before year-end. Many everyday medical purchases qualify, including eyeglasses, prescriptions, dental care, and first-aid supplies.

Review filing status and dependency claims

Potential savings: $200–$1,000+

Filing status affects standard deductions, credits, and overall tax liability. Reviewing your situation can reveal savings, especially if you qualify for head of household status or can claim a dependent relative.

The Child Tax Credit is $2,000 per qualifying child, and the refundable Additional Child Tax Credit can provide up to $1,700, depending on income. Eligibility requires at least $2,500 of earned income. Parents, caregivers, and those supporting aging relatives should review all dependency criteria.

Bottom line

These end-of-year tax strategies can meaningfully reduce your taxable income, boost deductions, and help you keep more cash in your wallet. By taking advantage of updated IRS limits, available credits, and timing strategies, you can position yourself for meaningful tax savings as the year closes.

A little planning now can strengthen your financial footing going into the new year and give you more control over what you owe — or what you get back — at tax time.
