These are the questions we hear most often about the refund estimator — what it does and doesn't cover, how to read the result, and how to make the estimate more accurate. If you're deciding between the standard deduction and itemizing, see the dedicated standard vs. itemized deduction page for that decision in depth; for the exact calculation steps, see the methodology page.
Is this exact to the dollar? +
No — this is a simplified planning estimate that uses federal tax brackets by filing status. It does not include state income tax, self-employment tax, the alternative minimum tax, or every credit and deduction that could apply to your specific situation. Your actual return, prepared with tax software or a tax professional using your complete tax documents, is the only way to know your exact result.
Does this file my taxes? +
No. This is an estimate tool only — it does not prepare, e-file, or submit anything to the IRS or any state tax agency. It's meant to help you plan and understand your numbers before you file with tax software, a tax professional, or the IRS's own free filing options.
Is my data stored anywhere? +
No. All calculations happen locally in your browser using the numbers you type in — nothing you enter into the calculator fields is sent to a server, stored in a database, or shared with any third party. You can close the tab and none of your inputs persist anywhere.
Why did my estimated refund change from what I got last year? +
A refund estimate moves whenever any input changes: a raise or pay cut, a new job with different withholding, marriage or divorce, a new dependent, a change in itemized deductions, or a tax credit you qualified for last year but not this year. Tax rules themselves are also updated for each tax year, so brackets, the standard deduction amount, and some credit rules can shift year to year even if your income stays flat. If last year's refund was unusually large or small, it's often a withholding issue rather than an income issue — see the next question.
What's the difference between a refund and just having less withheld? +
A refund means you paid the government more through withholding during the year than you actually owed, so the IRS returns the difference after you file. It is not a bonus — it's your own money paid back to you, without interest. If you consistently get a large refund, you may be having more withheld from each paycheck than necessary; adjusting your W-4 with your employer can put more of that money in your regular paychecks throughout the year instead of waiting for a refund.
Does this calculator include state taxes? +
No — this estimator is federal-only. State income tax rules, brackets, and deductions vary widely (and some states have no income tax at all), so a federal-only estimate will not reflect your total state-plus-federal tax picture. If your state has an income tax, budget separately for that using your state's own tax agency resources.
Should I use the standard deduction or itemize? +
It depends on whether your total itemizable expenses — mortgage interest, state and local taxes (subject to a cap), charitable contributions, and qualifying medical expenses above a certain share of your income — add up to more than your standard deduction amount for your filing status. Most filers, especially renters and those without large deductible expenses, come out ahead with the standard deduction because it's simpler and often larger. See the full
standard vs. itemized comparison for a detailed breakdown of when each one wins.
What counts as a tax credit versus a deduction? +
A deduction reduces the amount of income that gets taxed — it saves you your tax rate times the deduction amount. A credit reduces your actual tax bill dollar-for-dollar, which generally makes it more valuable. Common credits include the child tax credit, education credits, and dependent care credits; eligibility and amounts depend on your income, filing status, and specific circumstances, so confirm your eligibility for any credit before assuming it applies to you.
I'm self-employed or have 1099 income — does this work for me? +
This calculator estimates federal income tax on your entered income but does not calculate self-employment tax (the Social Security and Medicare tax that self-employed workers pay directly, since there's no employer to withhold it). If most of your income comes from freelance, contract, or self-employed work, your actual tax liability will likely be higher than this estimate suggests, and you may also need to make quarterly estimated tax payments during the year rather than relying on withholding.
Can I trust this for a big financial decision? +
Use it for planning and getting oriented — not as the sole basis for a major financial decision like a large purchase, a loan application, or adjusting your withholding dramatically. Because it's a simplified federal-only estimate, it can be meaningfully off from your actual result. For anything consequential, verify your numbers with a qualified tax professional or with the IRS's own tools and current-year published figures.
