❓ Bonus Take-Home Calculator FAQs

1. What is a gross bonus?
It’s the total bonus amount before any deductions like taxes or retirement contributions.

2. Why is my net bonus so much lower than expected?
Taxes (federal, state, Social Security, and Medicare) and contributions (like 401(k) or HSA) can reduce your bonus by 30–50%.

3. How are bonuses taxed?
Bonuses are typically taxed as supplemental wages using a flat federal rate of 22% (for bonuses under $1M).

4. Does my state affect my bonus take-home?
Yes. States like California and New York have higher tax rates, while Texas and Florida have no state income tax.

5. Can I reduce my bonus taxes?
Yes, contributing to a 401(k) or HSA lowers your taxable income, reducing your tax burden.

6. What if my bonus pushes my income into a higher bracket?
The tool accounts for your total income when applying tax rates. Only the income in the higher bracket is taxed at that rate.

7. Why enter my annual salary?
It helps determine your overall tax bracket and eligibility for certain deductions.

8. Is this tool accurate for self-employed individuals?
It’s best for W-2 employees. Self-employed taxes (like SECA) are not currently calculated.

9. What’s the Social Security wage base?
It’s the maximum income subject to Social Security tax. For example, in 2023 it was $160,200.

10. How does the Medicare surtax work?
If your income exceeds $200,000, an additional 0.9% Medicare tax applies to the excess.

11. What happens if I contribute too much to my 401(k)?
You may face tax penalties. Make sure your total contributions across income types don’t exceed IRS limits.

12. Can I use this for RSUs or stock bonuses?
Only if you’re receiving the value as cash. Equity vesting and taxation are more complex.

13. Does the calculator include local city taxes?
No, it focuses on federal and state-level taxes. Cities like NYC or San Francisco may have additional withholdings.

14. Can I change my bonus withholdings?
Typically, no. Employers often apply a flat rate, but check with HR.

15. Are the tax rates up-to-date?
Yes, the calculator uses current tax year brackets and rates as closely as possible.

16. Does it account for filing jointly or separately?
This version assumes a single filer. Joint or head-of-household rates may differ.

17. What if I don’t see my state?
Choose “Federal Only” for a general estimate. Full state support may be added soon.

18. Can I use it on mobile devices?
Absolutely. The calculator is mobile-friendly and works on smartphones and tablets.

19. How often should I update my numbers?
Whenever your salary, bonus amount, or contributions change.
