Common Questions

Frequently Asked Questions

Straight answers to the questions we hear most.

Most people miss deductions in three areas: business use of their home or car (the home office deduction and mileage tax write-offs are among the most underclaimed), medical expenses that exceed the 7.5% AGI threshold, and professional development costs like courses and certifications. Start with our Can I Deduct This? directory to get quick answers on specific expenses, or use the AI Deduction Finder to surface the most relevant ones for your situation.
The IRS issues most refunds within 21 days of e-filing. Paper returns take 6–8 weeks. If you claimed the Earned Income Tax Credit or Additional Child Tax Credit, the IRS cannot issue your refund before mid-February by law. You can track your exact status using the IRS Where’s My Refund tool, or read our full Tax Refund Guide for a step-by-step walkthrough.
Yes — you can amend a return up to 3 years after the original due date using Form 1040-X. This is useful if you missed deductions, made an error, or your filing status changed. If the amendment results in a larger refund, the IRS will send you the difference. Our Tax Amendment Guide walks through the process step by step, including how to track your amended return status.
Our calculators use the same formulas published in official IRS guidance — the 7.5% AGI threshold for medical expenses, the 70¢/mile standard mileage rate for 2025, and the simplified vs. actual method rules for home office deductions. They give you a strong estimate of your deductible amount, but they are not a substitute for professional tax preparation. Think of them as a starting point for an informed conversation with your CPA — not a final tax return. Always consult a licensed tax professional for advice specific to your situation.
For 2025, the standard deduction is $15,000 for single filers and $30,000 for married filing jointly. Itemizing deductions is only worth it if your qualifying expenses — mortgage interest, medical costs, state and local taxes, charitable contributions — exceed those amounts. Our calculators help you understand the value of your individual deductions so you can make that comparison with real numbers.
A tax deduction reduces your taxable income — so a $1,000 deduction saves you $220 if you’re in the 22% bracket. A tax credit reduces your actual tax bill dollar-for-dollar — a $1,000 credit saves you $1,000. This site focuses on deductions (also called tax write-offs), which are the most widely applicable for self-employed individuals, homeowners, and people with significant medical expenses.
