Understanding the 2025-2026 Tax Impact Comparison
The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, made many 2017 Tax Cuts and Jobs Act provisions permanent and added new deductions for tip income, overtime pay, auto loan interest, and seniors. But tax brackets, the standard deduction, and OBBBA's own thresholds are all indexed for inflation each year — so your actual liability can shift from one tax year to the next even without any change in income.
This calculator runs your full tax picture — wages, deductions, capital gains, self-employment income, credits, NIIT, and AMT — through both the 2025 and 2026 tax-year rules side by side, so you can see exactly where the difference comes from rather than guessing.
How This Calculator Works
Enter your wages, other income, deductions (standard or itemized), and whether to include capital gains, self-employment tax, credits, NIIT, or AMT. The calculator computes your full federal tax liability under both the 2025 and 2026 bracket, standard deduction, and phase-out figures using the same underlying tax engine as the site's other calculators, then shows the two results side by side along with the dollar and percentage difference.
