Tax Calculation Formula

The tax calculation follows these steps:

Federal Tax Formula:

Tax = (Taxable Income × Federal Tax Rate) + Additional Credits

This formula provides an estimate. Actual tax liability may vary based on your specific situation and local tax laws.

Worked Examples

Example 1: Single Filer

For a single filer with $50,000 gross income and no deductions:

Taxable income = $50,000 - $0 (deductions) - $13,850 (standard deduction) = $36,150
Federal tax = ($36,150 × 22%) + ($10,929 × 12%) + ($25,225 × 24%) = $8,000
State tax (California example) = $36,150 × 1% = $362
Total tax = $8,000 + $362 = $8,362

Example 2: Married Filing Jointly

For a married couple filing jointly with $100,000 gross income and $20,000 in deductions:

Taxable income = $100,000 - $20,000 - $27,700 = $52,300
Federal tax = ($52,300 × 12%) + ($36,100 × 22%) + ($14,100 × 24%) = $12,000
State tax (New York example) = $52,300 × 4% = $2,092
Total tax = $12,000 + $2,092 = $14,092
