25 Most Popular Tax Deductions and Credits for 2026

Tax deductions and credits are the two main ways to reduce your tax bill. The difference matters: deductions reduce your taxable income, while credits reduce your actual tax owed dollar-for-dollar. Here are the 25 most impactful deductions and credits available in 2026.

Tax Deductions vs. Tax Credits
