Calculating Taxable Income

Taxable income is calculated as follows:

Where:

• Gross Income is your total income before any deductions.
• Deductions are expenses you can subtract from your income (e.g., retirement contributions, student loan interest).
• Standard Deduction is the fixed amount based on your filing status.

The calculator uses this formula to determine your taxable income before applying the tax rates.

Common Tax Credits

Tax credits directly reduce your tax liability dollar-for-dollar. Some common tax credits for 2021 include:

• Child Tax Credit: Up to $2,000 per qualifying child.
• Earned Income Tax Credit (EITC): Up to $6,660 for individuals with low to moderate income.
• American Opportunity Credit: Up to $2,500 per eligible student.
• Saver's Credit: Up to $1,000 for retirement contributions.

These credits are not included in the calculator's estimate but can significantly reduce your tax liability. Consult a tax professional for details on eligibility and application.

Example Calculation

Let's calculate the estimated taxes for a single filer with $50,000 in gross income, no additional deductions, and no tax credits.

1. Gross Income: $50,000
2. Deductions: $0
3. Standard Deduction: $12,550
4. Taxable Income: $50,000 - $0 - $12,550 = $37,450
5. Federal Tax:
   • $9,950 × 10% = $995
   • ($40,525 - $9,950) × 12% = $3,649
   • ($37,450 - $40,525) × 22% = $205
   • Total Federal Tax: $995 + $3,649 + $205 = $4,849
6. State Tax (California example):
   • State Standard Deduction: $4,723
   • State Taxable Income: $37,450 - $4,723 = $32,727
   • California Tax: $32,727 × 1% = $327
7. Total Estimated Tax: $4,849 (federal) + $327 (state) = $5,176

This example shows an estimated tax liability of $5,176 for a single filer with $50,000 in gross income in California. Your actual tax liability may differ based on your specific circumstances.
