Taxes

Federal tax brackets, deductions, credits, and the 2026 changes from the One Big Beautiful Bill Act.

U.S. federal income tax is governed by the Internal Revenue Code, administered by the IRS, and adjusted each year for inflation. The 2026 tax year is unusual: the One Big Beautiful Bill Act (P.L. 119-21, signed July 4, 2025) created several new deductions on top of the regular inflation adjustments — a $25,000 deduction on tips, a $12,500 deduction on overtime, a $6,000 senior deduction for filers 65 and older, and a $10,000 deduction on auto loan interest. All four phase out above specific income thresholds and apply to tax years 2025 through 2028.
