If you cannot use Form 1040EZ or Form 1040A, you must use Form 1040. You can use Form 1040 to report all types of income, deductions, and credits.
You may have received Form 1040A or Form 1040EZ in the mail because of the return you filed last year. If your situation has changed this year, it may be to your advantage to file Form 1040 instead. You may pay less tax by filing Form 1040 because you can take itemized deductions, some adjustments to income, and credits you cannot take on Form 1040A or Form 1040EZ.
You must use Form 1040 if any of the following apply.
- Your taxable income is $100,000 or more.
- You itemize your deductions.
- You had income that cannot be reported on Form 1040EZ or Form 1040A, including tax-exempt interest from private activity bonds issued after August 7, 1986.
- You claim any adjustments to gross income other than the adjustments listed earlier under Form 1040A.
- Your Form W-2, box 12, shows uncollected employee tax (social security and Medicare tax) on tips or group term life insurance.
- You received $20 or more in tips in any one month and did not report all of them to your employer.
- You claim any credits other than the credits listed earlier under Form 1040A.
- You owe the excise tax on insider stock compensation from an expatriated corporation.
- Your Form W-2 shows an amount in box 12 with a code Z.
- You have to file other forms with your return to report certain exclusions, taxes, or transactions.
