The forms you need depend on your income type and life situation, not on how much you earned
The IRS does not send you a list of which forms to file. Instead, you figure it out based on what happened during the year — whether you worked for an employer, ran a business, got married, had a child, sold property, or received certain kinds of income. This section walks you through the main forms and who files them.
Start with Form 1040, the basic individual income tax return. Nearly everyone files this one. Then add forms based on your specific situation. If you worked for an employer, you will receive a W-2 from them by January 31. If you were self-employed or had freelance income, you will file Schedule C along with your 1040. If you had investment income, you may need Schedule B or Schedule D. The key is matching your income type to the right form.
Key Takeaways
- Form 1040 is the main return nearly all individual filers submit, and you attach other forms to it based on what income you received.
- W-2 forms from employers and 1099 forms from other income sources tell you what to report, and you must have received them by January 31 to file on time.
- Self-employed people file Schedule C to report business income and expenses, and also pay self-employment tax on Schedule SE.
- Married couples can file jointly on one 1040 or separately on two, and the choice affects which forms and deductions you can use.
- Life changes like marriage, divorce, having a child, or buying a home may require additional forms or schedules you did not file before.
Forms for wage and salary income
If you worked for an employer, your employer sends you a W-2 form by January 31. This form shows your gross wages, federal income tax withheld, Social Security tax, and Medicare tax. You do not file the W-2 itself — you use the numbers from it to fill out your 1040. If you worked for more than one employer during the year, you will receive multiple W-2s, and you report income from all of them on the same 1040.
Some employers also issue a W-2G if you won gambling winnings, or a W-2c if they made a mistake on your original W-2 and are sending a corrected version. You report the corrected W-2c instead of the original.
If you received wages but your employer did not withhold enough tax, or if you had no withholding at all, you may owe tax when you file. If too much was withheld, you will receive a refund. The W-2 tells you exactly how much was taken out.
Forms for self-employment and business income
If you were self-employed — meaning you ran your own business, worked as a contractor, or had freelance income — you report that income on Schedule C, which attaches to your 1040. Schedule C is where you list your business income and subtract your business expenses to find your net profit or loss. Common expenses include supplies, equipment, home office costs, vehicle mileage, and professional services.
You will also file Schedule SE to calculate self-employment tax, which covers both the employer and employee portions of Social Security and Medicare tax. If you are self-employed, you pay both portions yourself, unlike wage earners whose employers pay half. Schedule SE calculates what you owe based on your net profit from Schedule C.
If you received income from self-employment but it was less than $400 for the year, you do not have to file Schedule SE, though you may still need to file your 1040 for other reasons. If you had a business loss, you can use it to offset other income on your return.
Forms for investment and other income
Investment income comes in several forms, each with its own reporting document. If you received interest from a bank or bond, you will get a 1099-INT. If you received dividends from stocks or mutual funds, you will get a 1099-DIV. You report these on Schedule B if your total interest and dividends exceed $1,500, or you can report smaller amounts directly on your 1040.
If you sold stocks, mutual funds, real estate, or other property at a gain or loss, you report the sale on Schedule D and Form 8949. These forms calculate your capital gain or loss, which may be taxed at a different rate than ordinary income. Long-term capital gains (assets held more than one year) are usually taxed at lower rates than short-term gains.
Other income sources have their own forms: 1099-NEC for non-employee compensation (contract work), 1099-MISC for miscellaneous income like rental income or prizes, 1099-G for unemployment benefits or state tax refunds, and 1099-R for retirement distributions. Each one tells you what to report on your 1040.
Forms for dependents and family changes
If you have a child or other dependent, you claim them on your 1040 by listing their name and Social Security number. You do not file a separate form for each dependent — you list them all on the main return. However, if you claim the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit, you may need to file Schedule EIC to calculate those credits.
If you got married during the year, you can file jointly with your spouse on one 1040, or you can file separately on two returns. Filing jointly usually results in lower tax, but filing separately may be better in some situations — for example, if one spouse has very high medical expenses or large casualty losses. The choice affects which deductions and credits you can claim.
If you got divorced or legally separated, your filing status changes to single or head of household starting the year after the divorce is final. If you paid alimony (spousal support) to an ex-spouse, you may be able to deduct it. If you received alimony, you report it as income. The rules for alimony changed in 2019, so check whether your situation qualifies under current law.
Forms for deductions and credits
If you own a home and paid mortgage interest or property taxes, you may be able to deduct those amounts. You do not file a separate form — you claim the deduction on Schedule A if you itemize deductions instead of taking the standard deduction. Your mortgage lender sends you a 1098 showing how much interest you paid.
If you made charitable donations, paid student loan interest, or had significant medical expenses, you may file Schedule A to itemize those deductions. The standard deduction for 2024 is $14,600 for single filers and $29,200 for married couples filing jointly, so you only benefit from itemizing if your deductions exceed that amount.
If you paid education expenses for yourself or a dependent, you may claim the American Opportunity Credit or Lifetime Learning Credit using Form 8863. If you paid student loan interest, you can deduct up to $2,500 directly on your 1040 without itemizing. If you received a scholarship or grant, you report it on your return, though scholarships used for tuition are usually not taxable.
Forms for special situations
If you received a distribution from a retirement account like an IRA or 401(k), you will get a 1099-R showing the amount. You report this on your 1040. If you took money out before age 59½, you may owe an early withdrawal penalty unless an exception applies, such as a first-time home purchase or medical hardship.
If you sold your home, you may have a capital gain. You report the sale on Schedule D. However, if you lived in the home for at least two of the last five years, you can exclude up to $250,000 of gain (or $500,000 if married filing jointly) from your income, so you may owe no tax even if you made a profit.
If you had a significant loss in a business or investment, you may be able to carry that loss forward to future years to offset future income. This requires filing Form 8949 and Schedule D to document the loss and show how you are using it.
How to know which forms to file
The IRS publishes a Form 1040 instructions booklet each year that walks through which schedules and forms you need based on your situation. You can read it free from IRS.gov. Tax software also guides you through questions about your income and life situation, then automatically generates the forms you need.
If you received a form like a W-2 or 1099, you must report the income shown on it. You cannot ignore a form because you think the amount is wrong — you report what the form says, and if there is an error, you contact the issuer to request a corrected form. If you received a form in error (for example, a 1099-NEC for work you did not do), contact the issuer and ask them to issue a corrected form showing zero income.
The key rule: file every form that matches your income or situation, even if you think you might not owe tax. The IRS receives copies of most forms you receive, so they will notice if you do not report income that appears on a form sent to them.
Frequently Asked Questions
Do I have to file if I only had W-2 income and no other income?
It depends on how much you earned. For 2024, single filers must file if their gross income was $14,600 or more, and married couples filing jointly must file if their combined income was $29,200 or more. If you earned less and had no other income, you do not have to file, though you may want to if you had taxes withheld — you would get a refund.
What if I received a 1099 form but I think the amount is wrong?
Contact the person or business that issued the form and ask them to send you a corrected version. Do not ignore the form on your return. The IRS receives a copy, and if you do not report the income, they will send you a notice. Once you have the corrected form, file an amended return if needed.
Can I file without all my forms if I need to file by the important date?
You can file your return without a form if you have not received it by the filing important date, but you must report the income based on what you know. When you receive the missing form later, check it against what you reported. If there is a difference, file an amended return. You can also request an extension to give yourself more time to gather forms.
Do I need to file Schedule A if I rent instead of own a home?
You only file Schedule A if you itemize deductions, which means your deductions exceed the standard deduction. Renters can still itemize if they have charitable donations, medical expenses, or other deductible items that add up to more than the standard deduction. Most renters take the standard deduction instead.
What if I had both W-2 income and self-employment income?
You report the W-2 income on your 1040 and the self-employment income on Schedule C. You also file Schedule SE to calculate self-employment tax on the business income. Both types of income go on the same 1040 return.
