What happens when you file taxes for the first time

Filing taxes for the first time means sending the IRS a record of the money you earned last year and figuring out whether you owe them money or they owe you a refund. You do this by filling out a form (usually Form 1040 or a shorter version), gathering documents that show your income, and either mailing the form or filing it online. The IRS then processes your return, checks it against what your employer or bank reported, and either sends you a refund or bills you for what you owe.

Most people file once a year, by April 15 of the year after they earned the money. If you earned less than a certain amount — which varies by your age and whether someone claims you as a dependent — you may not have to file at all, though filing anyway can get you a refund of taxes your employer withheld from your paychecks.

Key Takeaways

  • You need a Social Security number or ITIN, your W-2 forms from employers (or 1099 forms if you were self-employed), and records of any deductions or credits you might claim.
  • The IRS important date is April 15, but filing earlier means you get a refund sooner if one is coming to you.
  • You can file for free using IRS Free File if your income is below a certain threshold, or use tax software that costs $0 to $200 depending on how complex your situation is.
  • If you make a mistake, you can file an amended return (Form 1040-X) within three years, so a wrong first filing is not permanent.
  • Keeping copies of what you filed and the documents you used to file it protects you if the IRS has questions later.

Gather your income documents before you start

Your employer sends you a W-2 form by January 31 if you worked for them during the previous year. This form shows how much you earned and how much tax was already taken out of your paychecks. If you worked for multiple employers, you will receive a W-2 from each one. Check the numbers against your own records — if a W-2 looks wrong, contact the employer's payroll department and ask them to issue a corrected one.

If you were self-employed or did freelance work, you will not receive a W-2. Instead, anyone who paid you more than $600 will send you a 1099-NEC form (or 1099-MISC in some cases). If you earned self-employment income but did not receive a 1099, you still have to report it. Keep records of invoices, bank deposits, or payment receipts to prove what you earned.

Gather any other income documents: interest statements from banks (1099-INT), dividend statements from investments (1099-DIV), or records of unemployment benefits you received. If you received a refund of state or local taxes, the IRS may send you a 1099-G. Have all of these in front of you before you open a tax form or software.

Decide whether to file on paper or online

Filing online is faster and more accurate because the software catches math errors and tells you right away if you are missing information. The IRS offers IRS Free File, which is free tax software you can use if your income was below a certain threshold in the previous year (the threshold changes yearly, so check IRS.gov for the current limit). You read the software, enter your information, and file electronically.

If your income is above the Free File limit, you can buy tax software from companies like TurboTax, H&R Block, or TaxAct. These range from $0 for basic versions to $200 or more if your situation is complicated (self-employment, rental income, investments). Many offer a free version for straightforward returns. You can also pay a tax preparer or CPA to file for you, which typically costs $150 to $500 depending on how complex your return is.

Filing on paper means printing the forms, filling them out by hand, and mailing them to the IRS address listed in the form instructions. This takes longer to process and is more prone to errors, so it is worth doing online if you can. If you do file on paper, keep a copy for your records and consider mailing it certified mail so you have proof the IRS received it.

Complete the main form and report your income

Most first-time filers use Form 1040, the main individual income tax form. You will enter your name, address, Social Security number, and filing status (single, married filing jointly, head of household, and so on). If someone claims you as a dependent — usually a parent — you will check that box.

Next, you report your income. If you have W-2 forms, you enter the total wages from all of them on the form. If you have 1099 forms, you enter that income in the section for self-employment or other income. The form walks you through where each type of income goes. If you are using software, it asks you questions and fills in the form for you.

After you report income, the form calculates your standard deduction — a set amount the IRS lets you subtract from your income before calculating tax. For 2024, the standard deduction was $14,600 for single filers and $29,200 for married couples filing jointly, but these amounts change yearly. Most first-time filers use the standard deduction rather than itemizing deductions, which is simpler and usually results in a lower tax bill.

Claim credits if you are may be able to access for them

A tax credit is different from a deduction: it directly reduces the tax you owe, dollar for dollar. Common credits for first-time filers include the Earned Income Tax Credit (EITC) if you earned less than a certain amount, the Child Tax Credit if you have children, or the American Opportunity Credit if you paid for college tuition. The form or software will ask you questions to determine which credits explore to you.

Do not skip the credits section. A credit can turn a small tax bill into a refund, or increase a refund you were already getting. If you are unsure whether you may have access to for a credit, the IRS website has a tool called the Interactive Tax Assistant that asks yes-or-no questions and tells you which credits you might be able to claim.

Review your return and file it

Before you submit, read through your return and check that all numbers match your documents. Make sure your name and Social Security number are spelled correctly — a typo here can delay your refund. Verify that you reported all income and that the tax withheld from your paychecks (shown on your W-2) is entered correctly.

If you are filing online, the software usually flags missing or inconsistent information before you can submit. If you are filing on paper, go through the form line by line and make sure you did not skip any sections. Sign and date the form — an unsigned return will be rejected.

Once you file, keep a copy of your return and all the documents you used (W-2s, 1099s, receipts, bank statements). The IRS can ask you about your return for up to three years after you file, and having these documents ready protects you. If you filed online, read and save the confirmation page the software gives you.

What to do if you made a mistake after filing

If you realize you made an error after you filed, you can file an amended return using Form 1040-X. You have three years from the original filing date to file an amendment. The amended return shows what you originally reported, what the correct information is, and the difference. You mail it to the IRS with a copy of your original return.

Amended returns take longer to process than original returns — usually eight to twelve weeks. If the amendment results in a refund, the IRS will send it to you. If it results in additional tax owed, you will receive a bill. Filing an amendment does not trigger an audit; it is a normal part of tax filing and the IRS processes thousands of them every year.

Frequently Asked Questions

Do I have to file taxes if I earned very little money?

If your income was below the standard deduction for your filing status, you are not required to file. However, if your employer withheld taxes from your paychecks, filing gets you a refund of that money. It is worth filing even if you are not required to, because you will likely get money back.

What if I do not have all my documents by April 15?

You can file for an automatic extension by submitting Form 4868 before April 15. This gives you until October 15 to file. Note that an extension to file is not an extension to pay — if you owe taxes, you should pay what you estimate you owe by April 15 to avoid penalties and interest, even if you have not filed yet.

Can I file my taxes myself, or do I need to hire someone?

You can file yourself using free or low-cost software if your situation is straightforward (one job, no investments, no business). If you are self-employed, own a business, or have complex income sources, hiring a tax preparer or CPA may catch deductions or credits you would miss and could save you money.

What happens if I owe taxes but cannot pay right away?

File your return on time even if you cannot pay the full amount. The IRS charges penalties and interest on unpaid taxes, but filing on time reduces the penalty. You can set up a payment plan with the IRS, or request an installment agreement to pay over time. Contact the IRS or work with a tax professional to arrange this.

Where do I mail my return if I file on paper?

The address depends on your state and whether you are including a payment. The Form 1040 instructions include a table with the correct mailing address for your situation. Using the wrong address delays processing, so check the current year's instructions before you mail.
