Formula and Tax Brackets
The 2019 federal income tax is calculated using progressive tax brackets. The formula is:
Federal Income Tax = Sum of (Taxable Income × Tax Rate) for each applicable bracket
The 2019 tax brackets for Married Filing Jointly are:
| Taxable Income Range | Tax Rate |
|---|---|
| $0 - $19,750 | 10% |
| $19,751 - $80,250 | 12% |
| $80,251 - $171,050 | 22% |
| $171,051 - $326,600 | 24% |
| $326,601 - $414,750 | 32% |
| $414,751 - $622,050 | 35% |
| $622,051+ | 37% |
The standard deduction for MFJ in 2019 was $24,800. This deduction reduces your taxable income before applying the brackets.
Worked Example
Let's calculate the federal income tax for a married couple with $100,000 taxable income:
- Subtract the standard deduction: $100,000 - $24,800 = $75,200 taxable income
- Apply tax brackets:
- $19,750 × 10% = $1,975
- ($80,250 - $19,750) × 12% = $60,500 × 12% = $7,260
- ($75,200 - $80,250) × 22% = $5,050 × 22% = $1,111
- Total tax = $1,975 + $7,260 + $1,111 = $10,346
This example shows how the progressive tax system applies higher rates to income in higher brackets.
