What a tax return actually is, and why you need one

A tax return is a form you send to the IRS that reports how much money you earned in a year and how much tax you already paid on it. The IRS uses this form to figure out whether you owe more tax, are owed a refund, or are even. You need to file one if you earned enough income to cross the threshold — that threshold changes each year and depends on your age and filing status.

The return itself is not the refund. The return is the paperwork. The refund is money the IRS sends back to you if you overpaid during the year. Many people use the words interchangeably, but they mean different things. You file a return; you receive a refund.

Key Takeaways

  • You must report all income sources — wages, self-employment, interest, dividends, rental income — even if no one sent you a tax form for it.
  • The standard deduction reduces your taxable income automatically; most people use it instead of itemizing deductions.
  • Tax software, the IRS Free File program, or a tax preparer can walk you through the calculation, but you provide the numbers.
  • Your refund or amount owed depends on total income minus deductions, minus taxes already withheld from paychecks or paid through estimated tax payments.

Gather your income documents before you start

The IRS expects you to report every dollar you earned. Start by collecting documents from every source: W-2 forms from employers, 1099 forms for self-employment or contract work, interest statements from banks, dividend statements from investments, and rental income records if you own property. If you received unemployment benefits, student loan interest payments, or Social Security, those have forms too.

If you earned less than $600 from a single source of self-employment income, you may not receive a 1099-NEC or 1099-MISC, but you still must report it. Write down the amount yourself. The IRS cross-checks W-2s and 1099s against your return automatically, so leaving something out creates a mismatch they will catch.

Gather receipts or records for any deductions you plan to claim — mortgage interest statements, property tax bills, charitable donation records, medical expense receipts, or business expense logs if you are self-employed. You do not send these with your return, but you must keep them in case the IRS asks.

Understand the standard deduction versus itemizing

The standard deduction is a flat amount the IRS lets you subtract from your income before calculating tax. For 2024, it ranges from $14,600 to $23,500 depending on your age and filing status. Most people use the standard deduction because it is simpler and often larger than the total of their individual deductions.

You can instead itemize deductions — add up specific expenses like mortgage interest, state and local taxes, charitable donations, and medical costs — if that total is larger than the standard deduction. Itemizing requires more record-keeping and is worth doing only if your deductible expenses are high. If you own a home with a mortgage, you are more likely to itemize. If you rent, you almost certainly will not.

You choose one or the other, not both. Tax software will calculate both and show you which saves more money.

Calculate your taxable income and tax owed

Start with your total income from all sources. Subtract the standard deduction (or your itemized deductions if that is higher). The result is your taxable income. The IRS tax tables or software then tell you how much federal income tax you owe based on that number and your filing status.

This is where tax brackets come in. You do not pay one flat rate on all your income. Instead, income is taxed in layers: the first portion at 10%, the next portion at 12%, and so on, up to 37% for the highest earners. Tax software does this calculation automatically. You do not need to understand the math — you need to know that earning more money does not push all your income into a higher bracket, only the income above that threshold.

After calculating tax owed, subtract any tax credits you may have access to for. Credits are different from deductions: a $1,000 credit reduces your tax by $1,000, while a $1,000 deduction reduces your taxable income by $1,000. Common credits include the Earned Income Tax Credit (EITC) if you earn below a certain amount, the Child Tax Credit, and education credits if you paid tuition.

Account for taxes you already paid during the year

If you work as an employee, your employer withholds federal income tax from each paycheck. That money goes to the IRS on your behalf. If you are self-employed, you make estimated tax payments four times a year. Either way, you have already paid some or all of your tax liability.

On your return, you report the total amount withheld or paid. The IRS compares this to the tax you actually owe. If you paid more than you owe, you get a refund. If you paid less, you owe the difference. If you paid exactly the right amount, you break even.

Your W-2 form shows federal income tax withheld in box 2. If you made estimated payments, you have records from the IRS or your payment service. Self-employed people often adjust their withholding the following year if they owed a large amount or received a large refund.

Choose how to file: software, Free File, or a preparer

The IRS Free File program is a partnership with tax software companies that offer free returns to people earning below a certain income threshold — usually around $79,000 for 2024, though this varies by company. You can find the list at IRS.gov. These are real tax programs; they are not stripped-down versions.

If you earn above the Free File threshold or prefer not to use software, you can buy commercial tax software like TurboTax, H&R Block, or TaxAct. These range from $60 to $200 depending on how complex your return is. They walk you through questions, fill in the forms, and file electronically.

You can also hire a tax preparer — a CPA, enrolled agent, or tax professional — to do the work for you. They charge by the hour or a flat fee, usually $150 to $500 for a straightforward return. A preparer is useful if you are self-employed, own rental property, have investment income, or are unsure what to report.

File your return and track your refund

Once you have entered all your information, the software or preparer files your return electronically with the IRS. Electronic filing is faster and more accurate than mailing a paper return. The IRS sends you a confirmation number immediately.

If you are owed a refund, you can choose direct deposit to your bank account or a paper check mailed to you. Direct deposit is faster — usually two to three weeks. A check takes longer. You can track your refund status on IRS.gov using your confirmation number, Social Security number, and the refund amount.

If you owe money, you can pay by credit card, debit card, bank transfer, or check. Paying by card or transfer incurs a fee. Paying by check does not, but the IRS must receive it by the filing deadline or you face penalties and interest.

Frequently Asked Questions

Do I have to file a return if I did not earn much money?

It depends on your income and filing status. The IRS sets a threshold each year — for 2024, it is around $14,600 for most single filers and $29,200 for married couples filing jointly. If you earned less, you do not have to file. However, if taxes were withheld from your paychecks, filing gets you a refund of that money.

What if I cannot find a 1099 form I need?

Contact the person or business that paid you and ask them to send a copy or confirm the amount. If they do not respond, report the income based on your own records — bank deposits, invoices, or payment receipts. The IRS has a copy of the 1099 they received, so reporting the same amount protects you.

Can I file my return myself without software or a preparer?

Yes, but it is not practical for most people. You can download the forms from IRS.gov and fill them out by hand, then mail them in. This takes much longer and is error-prone. Tax software is inexpensive or free and catches mistakes before you file.

What happens if I make a mistake on my return after I file?

You can file an amended return using Form 1040-X. You have three years to correct most mistakes. If the IRS finds an error, they will contact you and either send you a bill or refund, depending on the mistake.

When do I have to file my return?

The deadline is usually April 15 of the year after you earned the income. If April 15 falls on a weekend or holiday, the deadline moves to the next business day. You can request an automatic extension to October 15, but this extends only the filing deadline, not the payment deadline — taxes owed are still due April 15.
