Frequently Asked Questions (FAQ)

How accurate are the tax calculations?
Our tax calculator uses current federal tax brackets and standard deduction amounts. Results are estimates based on the information provided and may not reflect your exact tax situation. Always consult with a tax professional or use official IRS tools for final tax preparation.
What's the difference between effective and marginal tax rates?
Your marginal tax rate is the rate you pay on your last dollar of income (your highest tax bracket). Your effective tax rate is your total tax divided by your total income, representing your average tax rate across all income levels.
Should I itemize deductions or take the standard deduction?
Take whichever is higher. For 2023, the standard deduction is $13,850 for single filers and $27,700 for married filing jointly. Itemize if your mortgage interest, state/local taxes, charitable donations, and other qualifying expenses exceed these amounts.
How do I determine my state tax rate?
State tax rates vary significantly. Some states like Texas, Florida, and Nevada have no state income tax, while others like California and New York have rates over 10%. Check your state's department of revenue website for current rates and brackets.
What are FICA taxes and why can't I opt out?
FICA taxes fund Social Security (6.2%) and Medicare (1.45%). These are mandatory payroll taxes that provide future benefits. Social Security tax has an annual wage cap ($160,200 in 2023), but Medicare tax applies to all wages.
How can I reduce my tax withholding from my paycheck?
Update your W-4 form with your employer to claim more allowances or specify additional exemptions. Be careful not to under-withhold significantly, as you may owe taxes and penalties at year-end if you haven't paid enough throughout the year.
Do I need to pay sales tax on online purchases?
Most online retailers now collect sales tax for your state automatically. If they don't, you're technically required to pay "use tax" when filing your state tax return, though enforcement varies by state.
What happens if I don't pay enough taxes during the year?
You may owe penalties if you don't pay at least 90% of the current year's tax liability or 100% of last year's liability (110% if your prior year AGI exceeded $150,000). Make quarterly estimated payments if you expect to owe $1,000 or more.
Are there different tax rates for different types of income?
Yes. Ordinary income (wages, interest) is taxed at regular rates. Long-term capital gains and qualified dividends receive preferential rates (0%, 15%, or 20% depending on income). Short-term capital gains are taxed as ordinary income.
When should I consult a tax professional?
Consider professional help if you have complex situations like self-employment income, rental properties, significant investments, multiple income sources, or major life changes. The cost is often justified by potential tax savings and peace of mind.
