How the Calculator Determines Withholding

1. Calculate Adjusted Gross Income (AGI)

AGI=Total Income−Deductions\text{AGI} = \text{Total Income} – \text{Deductions}AGI=Total Income−Deductions

2. Apply Federal and State Tax Rates
   Uses IRS and state tax tables to determine accurate withholding.
3. Adjust for Allowances and Credits
   Reduces withholding based on dependents, exemptions, and tax credits.
4. Factor in Additional Withholding
   Includes any extra withholding you enter to ensure accuracy.
5. Output Per-Paycheck Withholding
   Shows exact federal and state withholding amounts, total annual tax, and estimated take-home pay.

Practical Example

Scenario:

• Filing Status: Married Filing Jointly
• Annual Salary: $70,000
• Dependents: 2
• Standard deduction: $27,700 (2025)
• Additional withholding: $30 per paycheck

Step 1: Adjusted Income
$70,000 – $27,700 = $42,300

Step 2: Federal Withholding using IRS tables
Estimated tax ≈ $4,230 annually

Step 3: Per-paycheck withholding (biweekly)
$4,230 ÷ 26 ≈ $162.69

Step 4: Include additional withholding
$162.69 + $30 = $192.69 per paycheck

✅ Ensures accurate withholding and predictable take-home pay.
