Real-Life Example

Let’s calculate the estimated tax for a single filer with an annual income of $60,000 in 2025:

• Annual Income: $60,000
• Tax Year: 2025
• Filing Status: Single

Step 1: Apply progressive tax rates:

• $\mathrm{First Income}=\mathrm{11,500}\times 0.10=\mathrm{1,150}$
• $\mathrm{Next Income}=\mathrm{33,225}\times 0.12=\mathrm{3,987}$
• $\mathrm{Remaining Income}=\mathrm{15,275}\times 0.22=\mathrm{3,360.50}$

Total Tax:

$\mathrm{Total Tax}=1150+3987+3360.50=\mathrm{8,497.50}$

Result: The estimated federal income tax is $8,497.50.
