Frequently Asked Questions
How is my tax bracket determined?
Your tax bracket depends on your taxable income and filing status. The U.S. uses a progressive system where different portions of your income are taxed at different rates. For example, if you’re single with $50,000 taxable income:
- First $11,600 taxed at 10% = $1,160
- Next $35,550 ($47,150 – $11,600) taxed at 12% = $4,266
- Remaining $2,850 ($50,000 – $47,150) taxed at 22% = $627
- Total tax: $1,160 + $4,266 + $627 = $6,053
Why do I owe taxes when my employer withholds money?
Withholding is an estimate. You might owe if:
- You had additional income not subject to withholding
- Your withholding allowances were set too high
- You had significant capital gains or other taxable events
- You’re self-employed and didn’t pay estimated taxes
What’s the difference between tax credits and deductions?
Deductions reduce your taxable income (e.g., $1,000 deduction saves $220 if you’re in 22% bracket). Credits directly reduce your tax bill dollar-for-dollar (e.g., $1,000 credit saves $1,000).
