Tax Refund
A tax refund is a reimbursement from the IRS when your tax withholding or estimated payments during the year exceeded your actual tax liability. A refund is not free money — it means you gave the government an interest-free loan.
The average federal tax refund is about $3,000. That sounds nice, but it means the average American overpaid by $250/month all year. Invested at a 7% return, that $250/month would grow to ~$3,150 — not the $3,000 refund you receive with no growth.
A refund is not inherently bad — it can be a forced savings mechanism — but from a purely financial standpoint, you want to owe close to $0 at filing time. Adjust your W-4 withholding after major life changes: marriage, new child, second job, or significant investment income.
Refundable tax credits (Earned Income Credit, Child Tax Credit) can generate a refund even if you owe $0 in tax. Non-refundable credits only reduce your tax to zero; they can't create a refund.

- Tax Withholding
- Tax withholding is the amount your employer deducts from each paycheck and remits directly to the IRS on your behalf. It is an advance payment toward your annual tax liability — not an extra tax. If too much is withheld, you get a refund; too little, and you owe at filing.
- W-2 Form
- A W-2 (Wage and Tax Statement) is a form employers send to employees each January. It reports total wages paid and all taxes withheld during the prior year. You need it to file your federal and state income tax returns.
- Adjusted Gross Income (AGI)
- Adjusted gross income (AGI) is your total gross income minus specific 'above-the-line' deductions such as student loan interest, IRA contributions, and self-employment taxes. AGI is the starting point for calculating taxable income and determines eligibility for many tax credits and deductions.
- Taxable Income
- Taxable income is the portion of your income that is actually subject to income tax. It equals adjusted gross income (AGI) minus either the standard deduction or itemised deductions. Federal income tax brackets are applied to this number — not your gross salary.
