TurboTax Online: Important Details about Filing Form 1040 Returns with Limited Credits

A Form 1040 return with limited credits is one that's filed using IRS Form 1040 only (with the exception of the specific covered situations described below). Roughly 37% of taxpayers are eligible.

If you have a Form 1040 return and are claiming limited credits only, you can file for free yourself with TurboTax Free Edition or TurboTax Live Assisted Basic (if available), or you can file with TurboTax Full Service at the listed price.

Situations covered (assuming no added tax complexity):

• W-2 income
• Interest or dividends (1099-INT/1099-DIV) that don’t require filing a Schedule B
• IRS standard deduction
• Earned Income Tax Credit (EITC)
• Child Tax Credit (CTC)
• Student loan interest deduction

Situations not covered:

• Itemized deductions claimed on Schedule A
• Unemployment income reported on a 1099-G
• Business or 1099-NEC income
• Stock sales (including crypto investments)
• Rental property income
• Credits, deductions and income reported on other forms or schedules
