Tax Brackets
The federal income tax uses progressive tax brackets, meaning higher incomes are taxed at higher rates. The 2023 tax brackets for single filers are:
| Taxable Income | Tax Rate |
|---|---|
| $0 - $11,000 | 10% |
| $11,001 - $44,725 | 12% |
| $44,726 - $95,375 | 22% |
| $95,376 - $182,100 | 24% |
| $182,101 - $231,250 | 32% |
| $231,251 - $578,125 | 35% |
| $578,126+ | 37% |
The brackets are different for married filing jointly, head of household, and other filing statuses. The calculator accounts for these differences.
Standard Deduction
The standard deduction reduces your taxable income by a fixed amount. For 2023, the standard deductions are:
- Single filers: $13,850
- Married filing jointly: $27,700
- Head of household: $20,800
- Married filing separately: $13,850
You can choose to take the standard deduction instead of itemizing your deductions. The calculator automatically applies the correct standard deduction based on your filing status.
Itemized Deduction
Itemized deductions allow you to subtract certain expenses from your income. Common itemized deductions include:
- Mortgage interest
- State and local taxes
- Medical expenses
- Charitable donations
- Casualty or theft losses
To itemize deductions, you must have expenses that exceed the standard deduction. The calculator can help you estimate whether itemizing would be beneficial for your situation.
Tax Credits
Tax credits directly reduce your tax liability dollar-for-dollar. Common tax credits include:
- Child Tax Credit
- Earned Income Tax Credit (EITC)
- American Opportunity Credit
- Lifetime Learning Credit
The amount of tax credit you qualify for depends on your income, filing status, and other factors. The calculator includes common tax credits in its calculations.
