State Income Tax Considerations

• Consider local taxes in some jurisdictions

Common Tax Deductions

Several deductions can reduce your taxable income:

• Standard Deduction: $13,850 for single filers, $27,700 for married filing jointly
• Itemized Deductions: For expenses like mortgage interest, medical expenses, and charitable contributions
• Retirement Contributions: Traditional IRA and 401(k) contributions

The calculator includes the standard deduction by default. For more accurate results, you may need to adjust for your specific deductions.

Worked Examples

Example 1: Single Filer with $50,000 Income

Using the calculator with $50,000 income and single filing status:

1. Taxable Income = $50,000 - $13,850 (standard deduction) = $36,150
2. First $11,000 taxed at 10% = $1,100
3. Next $33,725 taxed at 12% = $4,047
4. Remaining $1,425 taxed at 22% = $314
5. Total Federal Tax = $1,100 + $4,047 + $314 = $5,461

Example 2: Married Filing Jointly with $100,000 Income

Using the calculator with $100,000 income and married filing jointly:

1. Taxable Income = $100,000 - $27,700 = $72,300
2. First $22,000 taxed at 10% = $2,200
3. Next $67,450 taxed at 12% = $8,094
4. Remaining $1,950 taxed at 22% = $429
5. Total Federal Tax = $2,200 + $8,094 + $429 = $10,723
