8 Legal Ways to Reduce Your Tax Bill in 2026
Maximize your 401k contributions
Contributing to a traditional 401k reduces your taxable income dollar for dollar. Contributing the maximum $23,500 in 2026 could save $5,170 in taxes if you are in the 22% bracket.
Contribute to a traditional IRA
Traditional IRA contributions may be tax deductible depending on your income and whether you have a workplace retirement plan. The 2026 contribution limit is $7,000 or $8,000 if age 50 or older.
Use a Health Savings Account
HSA contributions are triple tax advantaged — tax deductible when contributed, tax-free growth and tax-free when used for medical expenses. You must have a high-deductible health plan to qualify.
Claim all eligible deductions
Common overlooked deductions include student loan interest, self-employment expenses, home office if self-employed, charitable donations and state and local taxes up to $10,000.
Take advantage of tax credits
Tax credits directly reduce your tax bill. Common credits include the Child Tax Credit, Earned Income Tax Credit, Child and Dependent Care Credit and education credits.
Harvest tax losses
If you have investments that have lost value you can sell them to realize a capital loss which offsets capital gains. You can also deduct up to $3,000 of net capital losses against ordinary income.
Consider timing your income
If you expect lower income next year defer income to next year and accelerate deductions into this year. Self-employed individuals have more flexibility to time income and expenses.
Give to charity strategically
Bunching multiple years of charitable donations into one year can help you exceed the standard deduction and itemize. Donating appreciated stock avoids capital gains tax and still gets the full deduction.
