Frequently Asked Questions
What's the difference between marginal and effective tax rates?
Your marginal tax rate is the percentage paid on your last dollar of income, while your effective tax rate is the average percentage of total income paid in taxes. The effective rate is usually lower due to progressive tax brackets.
How accurate are these tax calculations?
The calculator provides estimates based on 2023 federal tax brackets and standard deductions. Actual taxes may vary due to state-specific rules, additional deductions, credits, and other factors. Always consult a tax professional for official calculations.
What taxes are not included in this calculator?
This calculator doesn't include unemployment taxes, disability insurance, property taxes, local taxes, tax credits (like child tax credit), or additional Medicare tax on high earners. It provides a baseline estimate.
Why is my take-home pay different from what my employer calculates?
Employers may withhold different amounts based on your W-4 selections, additional deductions (health insurance, 401k), and other factors. This calculator shows the tax obligation, not necessarily what's withheld from paychecks.
How do state taxes vary across different states?
State income tax rates vary significantly - some states have no income tax, while others have rates over 10%. Some states also have local income taxes. Always check your specific state and local tax requirements.
When should I consider adjusting my tax withholdings?
Consider adjusting withholdings when you have major life changes (marriage, new job, additional income), if you consistently owe money or get large refunds, or when tax laws change significantly.
