You can do your own taxes by working through a short sequence: confirm you need to file, gather your income forms, pick a filing method, complete Form 1040, and submit it by April 15. If your adjusted gross income is $89,000 or less, the IRS Free File program gives you guided software at no cost.1Internal Revenue Service. E-File – Do Your Taxes for Free Most people with a W-2 and the standard deduction can finish in under an hour.
Do You Actually Need to File
Filing is only required once your gross income crosses a threshold set by your filing status and age. For tax year 2025 (the return you file in 2026), the minimums are:
- Single, under 65: $15,750
- Single, 65 or older: $17,550
- Married filing jointly, both under 65: $31,500
- Married filing jointly, both 65 or older: $34,700
- Head of household, under 65: $23,625
- Married filing separately, any age: $5
Below those numbers you generally don’t owe a return.2Internal Revenue Service. Check If You Need to File a Tax Return You may still want to. If your employer withheld federal tax from your paychecks, filing is the only way to get that money back. Refundable credits like the Earned Income Tax Credit work the same way: no return, no payment.
One exception overrides the thresholds. If your net earnings from self-employment reached $400 or more, you must file regardless of total income.
Gather Your Documents Before You Start
Every person on the return needs a Social Security Number or an Individual Taxpayer Identification Number — you, a spouse if filing jointly, and each dependent.3Office of the Law Revision Counsel. 26 USC 6109 – Identifying Numbers These appear on Social Security cards, prior-year returns, and ITIN letters. Pull them first so you’re not hunting mid-filing.
Income forms arrive by January 31. Employers send Form W-2 for wages and withholding.4Internal Revenue Service. Employment Tax Due Dates Freelance clients who paid you $600 or more send a 1099-NEC. Banks send 1099-INT for interest above $10, and brokerages send 1099-DIV for dividends.5Internal Revenue Service. Instructions for Forms 1099-INT and 1099-OID Check both your mailbox and any online account where a company might have posted forms digitally.
If you plan to itemize, gather supporting records too: Form 1098 from your mortgage lender, Form 1098-T from a college, charitable donation receipts, medical bills, and business expense records. A missing document usually means a missed deduction.
Pick a Filing Method
IRS Free File offers guided tax software free of charge if your adjusted gross income is $89,000 or under. Eight partner companies participate, each with slightly different age and income rules, so browse the full list on IRS.gov to find one you qualify for.6IRS.gov. IRS Free File – Browse All Offers The software asks plain-language questions and does the math. State returns may cost extra even when the federal one is free.
Above the Free File income cutoff, commercial software from providers like TurboTax, H&R Block, or TaxAct typically runs $30 to $120 for a federal return. The IRS also offers Free File Fillable Forms, which any income level can use, but it has no guidance and expects you to read the form instructions yourself.
Paper filing still works. Download Form 1040 and the schedules you need from irs.gov, complete them by hand, and mail the package. Paper returns take six weeks or more to process versus roughly three weeks for e-filed ones, so if you’re expecting a refund, e-file.7Internal Revenue Service. Refunds
Pick Your Filing Status
Filing status controls which brackets and deduction amounts apply to you. The IRS uses your marital and family situation on December 31.8Internal Revenue Service. Filing Status There are five choices:
- Single: unmarried, divorced, or legally separated as of December 31.
- Married filing jointly: both spouses on one return. Most couples pay less this way.
- Married filing separately: each spouse files their own return. Sometimes useful when one has high medical costs or income-driven student loan payments.
- Head of household: unmarried and paying more than half the cost of a home for a qualifying dependent. Better brackets and a larger deduction than single.
- Qualifying surviving spouse: available for two years after a spouse’s death if you have a dependent child.
Choosing the wrong status is one of the errors the IRS flags most often, and it can move your tax bill by thousands of dollars, so pick carefully.
Work Through Form 1040
Form 1040 collects every kind of taxable income on a single page. Start with wages, salaries, and tips from your W-2s. Add interest, dividends, freelance income, and capital gains from any investments you sold. That sum is your total income.
Next, subtract “above-the-line” adjustments to reach your adjusted gross income (AGI). Common adjustments include traditional IRA contributions, up to $2,500 of student loan interest, and half of self-employment tax if you owe any.9Internal Revenue Service. Topic No. 554 – Self-Employment Tax AGI determines your eligibility for most credits and deductions further down.
Standard Deduction or Itemize
From AGI, subtract your deduction. Most filers take the standard deduction because it requires no receipts. For tax year 2025:
- Single or married filing separately: $15,750
- Married filing jointly or qualifying surviving spouse: $31,500
- Head of household: $23,625
These are the figures for the 2026 filing season.10Internal Revenue Service. Standard Deduction – IRS Courseware Itemize on Schedule A only if your qualifying expenses beat the standard amount. The largest itemized deductions for most people are mortgage interest, state and local taxes (capped at $10,000), and medical expenses that exceed 7.5% of AGI. If you don’t own a home or live in a low-tax state, the standard deduction almost always wins.
If you’re 65 or older, you get an additional standard deduction on top of the base — roughly $1,600 for single filers and $1,300 per qualifying spouse for 2025. A separate enhanced senior deduction of up to $6,000 per qualifying person also applies through 2028, phasing out above $75,000 modified AGI single or $150,000 joint.11Internal Revenue Service.

Calculate Tax and Apply Credits
Taxable income (AGI minus deduction) goes into the federal brackets. The U.S. system is progressive: 10% on the first slice of income, 12% on the next, and so on up to 37%. Only the income within each bracket is taxed at that rate, so moving into a higher bracket doesn’t retroactively raise the rate on everything below.12Internal Revenue Service. Federal Income Tax Rates and Brackets Any software will handle this lookup for you.
Credits reduce the resulting tax dollar for dollar. The Child Tax Credit is worth up to $2,200 per qualifying child under 17, with up to $1,700 per child refundable through the Additional Child Tax Credit if your tax liability is too small to absorb the full amount.13Internal Revenue Service. Child Tax Credit The Earned Income Tax Credit ranges from $649 with no children to $8,046 with three or more qualifying children for tax year 2025 and is fully refundable.14Internal Revenue Service. Earned Income and Earned Income Tax Credit (EITC) Tables The IRS estimates millions of eligible filers miss it every year, so run through the eligibility questions carefully.
Finally, the form subtracts what you’ve already paid — employer withholding from your W-2, plus any estimated payments. If payments exceed tax, you get a refund. If they fall short, you owe the difference.
If You Have Self-Employment or Gig Income
Freelancers, contractors, rideshare drivers, and anyone earning outside a W-2 job report business income and expenses on Schedule C. The net profit flows onto your 1040 as part of total income.
Self-employment income also triggers a 15.3% self-employment tax, covering both halves of Social Security (12.4%) and Medicare (2.9%).15Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) The Social Security portion applies only up to $184,500 in combined wages and self-employment income for 2026.16Social Security Administration. Contribution and Benefit Base You can deduct half of the self-employment tax as an adjustment to income.
Because nobody withholds tax from a freelance check, the IRS expects you to pay quarterly. You generally owe estimated payments if you expect to owe at least $1,000 after withholding and refundable credits.17Internal Revenue Service. Form 1040-ES – Estimated Tax for Individuals (2026) The four due dates are:
- April 15, for income earned January through March
- June 15, for income earned April and May
- September 15, for income earned June through August
- January 15 of the following year, for income earned September through December
Missing a quarter creates an underpayment penalty calculated as interest on what you should have sent.18Internal Revenue Service. Estimated Tax A rough payment based on last year’s liability is far better than nothing.
Submit, Then Pay or Get Your Refund
The deadline for a 2025 federal return is April 15, 2026.19Internal Revenue Service. IRS Announces First Day of 2026 Filing Season E-filing is fastest. Your software will let you review everything, then have you sign electronically using a self-selected PIN or last year’s AGI. Save the confirmation number the system generates. If you file on paper, print your 1040 and every schedule, attach copies of your W-2s, and mail to the service center listed in your form instructions. Use certified mail with a return receipt. A paper return is on time if postmarked by the deadline.
Owe money? Pay by April 15 to avoid penalties. IRS Direct Pay moves funds from a bank account at no charge. Debit and credit card payments go through approved processors that charge a fee. If you can’t pay in full, apply online for a monthly installment agreement. The failure-to-pay penalty drops from 0.5% per month to 0.25% per month while an approved plan is in place.20Internal Revenue Service. Failure to Pay Penalty
Getting a refund? Direct deposit is fastest. You’ll enter your bank’s nine-digit routing number and your account number, both printed on personal checks or visible in your bank’s online portal. The IRS can split a refund across up to three accounts using Form 8888.21Internal Revenue Service. Form 8888 Verify every digit. One wrong number can delay the refund by weeks or send it to a stranger.
Don’t Forget Your State Return
Nine states have no individual income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Everywhere else, you also file a state return, and most state forms start with your federal AGI or taxable income. Many state revenue departments offer free e-filing directly on their websites. Commercial software usually charges an extra $25 to $50 to add a state return, so check the state agency site first.
After You File
The “Where’s My Refund?” tool on irs.gov shows return status once you’ve submitted. You’ll need your SSN, filing status, and the exact whole-dollar refund amount. The tool updates once a day, usually overnight, and shows status within 24 hours of e-filing or about four weeks after mailing paper.7Internal Revenue Service. Refunds
The IRS contacts taxpayers by mail through the U.S. Postal Service with a specific notice number. It does not initiate contact by email, text, or social media to ask for personal or financial information. Anyone doing that is running a scam. Respond promptly to real letters. Most minor issues, like a math error, get corrected automatically with an explanation mailed to you.
Consider signing up for an Identity Protection PIN through your IRS Online Account. It’s a free six-digit number that blocks anyone else from filing a return under your SSN.22Internal Revenue Service. Frequently Asked Questions About the Identity Protection Personal Identification Number (IP PIN)
Extensions
If April 15 is too soon, file Form 4868 to extend the filing deadline to October 15. The extension is automatic and requires no explanation.23Internal Revenue Service. About Form 4868 – Application for Automatic Extension of Time to File US Individual Income Tax Return It is not an extension to pay. If you owe, estimate the amount and send payment by April 15 to avoid the 0.5% monthly failure-to-pay penalty.20Internal Revenue Service. Failure to Pay Penalty Skipping both the return and the extension triggers a 5% monthly failure-to-file penalty, up to 25%.24Internal Revenue Service. Failure to File Penalty Filing late without an extension costs ten times more per month than paying late.
Amending a Return
If you find a mistake after filing (forgotten income, a missed deduction, the wrong filing status), file Form 1040-X. Most tax software can e-file an amended return. Processing usually takes 8 to 12 weeks, though some run to 16.25Internal Revenue Service. Form 1040-X – Amended US Individual Income Tax Return – Frequently Asked Questions To claim a refund on an amended return, file within three years of the original filing date or two years from the date you paid the tax, whichever is later.26IRS.gov. Instructions for Form 1040-X
Keeping Records
The IRS generally has three years from your filing date to audit, and up to six years if you underreported income by more than 25%.27Internal Revenue Service. IRS Audits Keep your completed return, W-2s, 1099s, deduction receipts, and IRS letters for at least three years. Records tied to property or investments with basis calculations should stay until you sell plus three years. You can request free copies of past returns through your IRS Online Account, by calling 800-908-9946, or by submitting Form 4506-T.28Internal Revenue Service. Transcript Types for Individuals and Ways to Order Them Mortgage lenders and financial aid offices routinely ask for transcripts, so knowing how to pull them saves time later.
