How to Calculate Federal Income Tax

Step 1: Calculate Gross Income

Gross Income = Wages + Interest + Dividends + Capital Gains + Self-Employment Income + Other Income

Step 2: Subtract Deductions

Taxable Income = Gross Income - Standard Deduction (or Itemized Deductions)

Choose the larger of:

Standard deduction (most people use this)
Itemized deductions (mortgage interest, state taxes, charitable donations)

Step 3: Apply Tax Brackets

Use the bracket table above for your filing status.

Step 4: Subtract Tax Credits

Tax Credits directly reduce your tax liability (unlike deductions which reduce taxable income).

Common credits:

Child Tax Credit: $2,000 per child
Earned Income Tax Credit (EITC): Up to $3,995 (depends on income)
American Opportunity Credit: Up to $2,500 for education
Lifetime Learning Credit: Up to $2,000 for education

Step 5: Calculate Final Tax

Federal Tax = Tax from Brackets - Tax Credits

Real-World Example: $100,000 Single Filer

Gross Income: $100,000

Deductions:

Standard Deduction: $14,600
Taxable Income: $85,400

Tax Calculation:

$0–$11,600 @ 10% = $1,160
$11,601–$47,150 @ 12% = $4,266
$47,151–$85,400 @ 22% = $8,415
Total Tax Before Credits: $13,841

Tax Credits:

Child Tax Credit: $2,000
Total Credits: $2,000

Federal Tax Owed: $13,841 - $2,000 = $11,841

Effective Tax Rate: 11.8%

Take-Home (after FICA): ~$75,000/year

Example: $200,000 Married Filing Jointly

Gross Income: $200,000

Deductions:

Standard Deduction: $29,200
Taxable Income: $170,800

Tax Calculation:

$0–$23,200 @ 10% = $2,320
$23,201–$94,300 @ 12% = $8,532
$94,301–$170,800 @ 22% = $16,830
Total Tax Before Credits: $27,682

Tax Credits:

Child Tax Credit (2 children): $4,000
Total Credits: $4,000

Federal Tax Owed: $27,682 - $4,000 = $23,682

Effective Tax Rate: 11.8%

Take-Home (after FICA): ~$150,000/year

Itemized vs Standard Deduction

When to Itemize

Itemize if your deductible expenses exceed the standard deduction:

Common Itemized Deductions:

Mortgage interest (up to $750,000 loan)
State and local taxes (SALT, capped at $10,000)
Charitable donations
Medical expenses (exceeding 7.5% of AGI)

Example: Married couple with:

Mortgage interest: $15,000
State taxes: $8,000
Charitable donations: $5,000
Total: $28,000 < $29,200 standard deduction
Verdict: Use standard deduction

Tax Credits vs Deductions

Deductions (Reduce Taxable Income)

Example: $10,000 deduction in 24% bracket = $2,400 tax savings

Credits (Reduce Tax Dollar-for-Dollar)

Example: $2,000 credit = $2,000 tax savings (regardless of bracket)

Credits are always more valuable than deductions.

2.9% for Medicare (on all income)

Total tax: ~$24,000

Combined income: $200,000
Total tax: ~$23,682
Savings: $318 by filing jointly
