You can reduce the amount you owe the IRS by lowering your taxable income, claiming every credit you qualify for, and adjusting your withholding so you’re not hit with a surprise bill in April. Most of these strategies are straightforward, and many can be set up once and left to run on autopilot for years.
Lower Your Taxable Income With Retirement Contributions
Every dollar you contribute to a traditional 401(k) or traditional IRA comes off your taxable income before the IRS calculates what you owe. This is the single most powerful lever most workers have. For 2026, you can contribute up to $24,500 to a 401(k), 403(b), or similar workplace plan. If you’re 50 or older, you can add another $8,000 in catch-up contributions, bringing the total to $32,500. Workers aged 60 through 63 get an even higher catch-up limit of $11,250.
If you don’t have access to a workplace plan, or want to save beyond it, you can contribute up to $7,500 to a traditional IRA for 2026, plus $1,100 more if you’re 50 or older. Traditional IRA contributions may be fully or partially deductible depending on your income and whether you’re covered by a workplace plan, so check the income phase-out ranges for your filing status.
The tax savings here are real and immediate. If you’re in the 22% tax bracket and contribute $24,500 to a 401(k), that’s roughly $5,390 less in federal tax for the year.
Use a Health Savings Account
If you have a high-deductible health plan, a Health Savings Account lets you set aside pre-tax money for medical expenses. Contributions reduce your taxable income, the money grows tax-free, and withdrawals for qualified medical costs are also tax-free. It’s the only account in the tax code with a triple tax advantage. HSA contribution limits are adjusted annually by the IRS, so check the current year’s cap for individual and family coverage.
Take the Right Deduction: Standard or Itemized
The standard deduction for 2026 is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household. You should itemize only if your total deductible expenses exceed those amounts. For most people, the standard deduction wins.
The expenses that count toward itemizing include state and local taxes (capped at $10,000), mortgage interest, charitable donations, and unreimbursed medical expenses above a percentage of your income. If you’re close to the threshold, you can sometimes “bunch” deductions by concentrating two years’ worth of charitable giving into a single year, pushing you over the standard deduction in that year and taking the standard deduction the next.
Claim Every Tax Credit You Qualify For
Credits are more valuable than deductions because they reduce your tax bill dollar for dollar rather than just lowering the income your tax is calculated on. A $1,000 credit saves you $1,000. A $1,000 deduction in the 22% bracket saves you $220.
Some credits are refundable, meaning they can give you money back even if you owe nothing in tax. The Earned Income Tax Credit is the most significant refundable credit for low- and moderate-income workers. You can claim it even if you don’t normally file a return.
Other credits worth checking:
- Child Tax Credit: Available for each qualifying child under a certain age.
- Child and Dependent Care Credit: Covers a portion of daycare or dependent care costs you pay so you can work.
- Education credits: The American Opportunity Credit and Lifetime Learning Credit help offset tuition and related expenses.
- Saver’s Credit: A credit for low- and moderate-income taxpayers who contribute to a retirement account.
- Clean vehicle credits: If you bought an eligible electric or plug-in hybrid vehicle, you may qualify for a credit of several thousand dollars.
- Home energy credits: Installing qualifying insulation, heat pumps, solar panels, or other energy improvements can generate credits.
- Premium Tax Credit: If you buy health insurance through the marketplace, this credit lowers your monthly premiums or reduces your tax bill at filing.
Credits have income limits, so check each one’s phase-out range. Even if you earned too much last year, a change in income or family size might make you eligible this year.
Deduct Business Expenses if You’re Self-Employed
Freelancers, independent contractors, and sole proprietors report income and expenses on Schedule C. Every legitimate business expense reduces your taxable income and, because self-employment tax is calculated on net profit, also lowers the 15.3% self-employment tax you pay on top of regular income tax.
Common deductible expenses include advertising, office supplies, software subscriptions, professional services, business insurance, contract labor, equipment, and business travel. Meals with a clear business purpose are generally 50% deductible. If you use your car for business, you can deduct actual vehicle costs or take the standard mileage rate, which was 70 cents per mile for 2025.
If you use part of your home regularly and exclusively for business, you can deduct a portion of your rent or mortgage interest, utilities, and insurance. The simplified method lets you deduct $5 per square foot of office space, up to 300 square feet, for a maximum $1,500 deduction without tracking individual expenses. The regular method requires calculating actual costs but often yields a larger deduction.
Self-employed workers can also deduct the employer-equivalent portion of their self-employment tax, 100% of their health insurance premiums (if they’re not eligible for coverage through a spouse’s employer), and contributions to a SEP-IRA or solo 401(k).
Adjust Your Withholding to Avoid a Year-End Bill
If you consistently owe a large balance when you file, the problem is usually that too little tax is being withheld from your paychecks throughout the year. The IRS offers a free Tax Withholding Estimator on its website that walks you through your income, deductions, and credits, then tells you exactly how to fill out a new Form W-4.
Once you complete the estimator, submit the updated W-4 to your employer, not to the IRS. Your employer adjusts the withholding from each paycheck going forward. You can update your W-4 at any time during the year, so if you get a raise, pick up a side job, or have a major life change like a new child, run the estimator again.
If you have income that doesn’t have taxes withheld, like freelance earnings, investment gains, or rental income, you’ll likely need to make quarterly estimated tax payments using Form 1040-ES. Paying these on time throughout the year prevents an underpayment penalty on top of the tax itself.
Time Your Income and Deductions
If you have some control over when you receive income or pay expenses, shifting them between tax years can make a meaningful difference. Deferring a year-end bonus into January pushes that income into the next tax year. Prepaying deductible expenses like property taxes or making charitable donations before December 31 pulls those deductions into the current year.
This strategy works best when your tax bracket will be meaningfully different from one year to the next, for example, if you’re retiring, starting a business, or expecting a large one-time payout. If your income is steady, the benefit of timing is smaller but still worth considering when you’re near a bracket boundary or the standard deduction threshold.
Contribute to Tax-Advantaged Education Accounts
Contributions to a 529 college savings plan don’t reduce your federal taxable income, but many states offer a state tax deduction or credit for contributions. The money grows tax-free, and withdrawals for qualified education expenses are also tax-free. If you’re saving for a child’s college costs, this is the most tax-efficient way to do it.
If you’re currently paying tuition, the American Opportunity Credit is worth up to $2,500 per eligible student for the first four years of higher education, and 40% of it is refundable. The Lifetime Learning Credit covers up to $2,000 per return for tuition at any level, including graduate school and professional development courses.
Donate Appreciated Assets Instead of Cash
If you itemize deductions and own stocks, mutual funds, or other investments that have gone up in value, donating them directly to a charity lets you deduct the full market value without paying capital gains tax on the appreciation. Selling the asset first and donating the cash triggers a taxable gain. This approach works with any asset held longer than one year and donated to a qualifying organization.
