2013 Tax Brackets
The 2013 federal income tax brackets are as follows:
The tax brackets are progressive, meaning higher income levels are taxed at higher rates.
| Filing Status | 10% Bracket | 15% Bracket | 25% Bracket | 28% Bracket | 33% Bracket | 35% Bracket | 39.6% Bracket |
|---|---|---|---|---|---|---|---|
| Single | $0 - $8,925 | $8,926 - $36,250 | $36,251 - $87,850 | $87,851 - $183,250 | $183,251 - $398,350 | $398,351 - $400,000 | $400,001+ |
| Married Filing Jointly | $0 - $17,850 | $17,851 - $72,500 | $72,501 - $146,400 | $146,401 - $228,850 | $228,851 - $405,700 | $405,701 - $457,600 | $457,601+ |
These brackets apply to taxable income after deductions and exemptions. The rates shown are the standard rates for 2013.
Standard Deduction
The standard deduction for 2013 was:
| Filing Status | Standard Deduction |
|---|---|
| Single | $6,200 |
| Married Filing Jointly | $12,400 |
| Married Filing Separately | $6,200 |
| Head of Household | $9,100 |
You can choose to take the standard deduction instead of itemizing your deductions. The standard deduction reduces your taxable income, potentially lowering your tax liability.
Calculating Taxable Income
Taxable income is calculated as:
Where:
- Gross Income is your total earnings before taxes
- Deductions include the standard deduction or itemized deductions
- Exemptions are personal exemptions for yourself and dependents
The calculator uses the standard deduction for simplicity. For more accurate results, you may need to adjust for your specific deductions and exemptions.
Example Calculation
Let's calculate the federal tax for a single filer with $50,000 in gross income:
- Subtract the standard deduction: $50,000 - $6,200 = $43,800
- Subtract personal exemptions: $43,800 - $3,900 (for yourself) = $39,900
- Apply the tax brackets:
- $0 - $8,925 at 10%: $8,925 × 0.10 = $892.50
- $8,926 - $36,250 at 15%: $27,325 × 0.15 = $4,100.75
- $36,251 - $39,900 at 25%: $3,649 × 0.25 = $912.25
- Total tax: $892.50 + $4,100.75 + $912.25 = $5,905.50
This example shows the tax calculation for a single filer with $50,000 in gross income. The actual tax owed may vary based on your specific circumstances.
Frequently Asked Questions
What is the difference between taxable income and gross income?
Gross income is your total earnings before any deductions or exemptions. Taxable income is what remains after subtracting deductions and exemptions from gross income.
How do I know if I should itemize or take the standard deduction?
Itemizing deductions can be beneficial if your itemized deductions exceed the standard deduction. The calculator uses the standard deduction for simplicity, but you may want to consult a tax professional for personalized advice.
Are there any additional taxes I need to pay besides federal income tax?
Yes, you may need to pay state income tax, Social Security tax, and Medicare tax. The federal income tax calculator only calculates the federal portion of your tax liability.
When is the tax filing deadline for 2013?
The tax filing deadline for 2013 was April 15, 2014. However, you may need to file an extension if you need more time to prepare your return.
