2021 US Federal Tax Brackets
The 2021 US federal income tax brackets are as follows:
Note: These tax brackets are for federal income tax only. State and local taxes may have different brackets and rates.
| Filing Status | 10% Bracket | 12% Bracket | 22% Bracket | 24% Bracket | 32% Bracket | 35% Bracket | 37% Bracket |
|---|---|---|---|---|---|---|---|
| Single | $0 - $9,950 | $9,951 - $40,525 | $40,526 - $86,375 | $86,376 - $164,925 | $164,926 - $209,425 | $209,426 - $523,600 | $523,601+ |
| Married Filing Jointly | $0 - $19,900 | $19,901 - $81,050 | $81,051 - $172,750 | $172,751 - $329,850 | $329,851 - $418,850 | $418,851 - $628,300 | $628,301+ |
| Married Filing Separately | $0 - $9,950 | $9,951 - $40,525 | $40,526 - $86,375 | $86,376 - $164,925 | $164,926 - $209,425 | $209,426 - $314,150 | $314,151+ |
| Head of Household | $0 - $14,200 | $14,201 - $54,200 | $54,201 - $86,350 | $86,351 - $164,900 | $164,901 - $209,400 | $209,401 - $523,600 | $523,601+ |
Standard Deduction Amounts
The standard deduction amounts for 2021 are as follows:
| Filing Status | Standard Deduction |
|---|---|
| Single | $12,550 |
| Married Filing Jointly | $25,100 |
| Married Filing Separately | $12,550 |
| Head of Household | $18,800 |
If you itemize your deductions, you may be able to reduce your taxable income by more than the standard deduction. However, the standard deduction is often simpler and may result in a lower tax liability for many taxpayers.
Example Calculation
Let's look at an example to see how the income tax calculator works. Suppose you are single and your total taxable income for 2021 is $50,000.
Using the 2021 tax brackets for single filers:
- $0 - $9,950: 10% tax = $995
- $9,951 - $40,525: 12% tax = $3,660
- $40,526 - $50,000: 22% tax = $2,104
Total estimated federal income tax = $995 + $3,660 + $2,104 = $6,759
Formula: Federal Income Tax = (Taxable Income × Tax Rate) + (Taxable Income × Tax Rate) + ...
This example shows how the income tax calculator breaks down your taxable income into the appropriate tax brackets and calculates the tax owed for each bracket.
Frequently Asked Questions
How do I know if I should itemize or take the standard deduction?
+To determine whether to itemize or take the standard deduction, compare the total of your itemized deductions to the standard deduction amount for your filing status. If your itemized deductions are greater than the standard deduction, you may want to itemize. However, keep in mind that itemizing can be more time-consuming and complex.
Are there any additional taxes I need to pay besides federal income tax?
+Yes, in addition to federal income tax, you may need to pay state and local income taxes, payroll taxes, self-employment tax, and other taxes depending on your situation. The income tax calculator only calculates federal income tax.
Can I use this calculator for estimated tax payments?
+Yes, you can use the estimated federal income tax from this calculator to help determine your estimated tax payments for 2021. However, it's important to consult with a tax professional or use the IRS's Withholding and Estimated Tax tool for more accurate estimates.
