No it is not illegal for TurboTax To charge a fee. There are two free versions of tax software available from TurboTax-- Free Edition and Free File. Your income level does not mean you can use any version of TurboTax you want to and get it for free.
You are posting from Deluxe $60
State return $50
Refund processing to have fees deducted from federal refund by 3rd party bank $39.99 ($44.99 in CA) (This fee is optional and can be avoided by paying TT upfront using a credit/debit card)
WHY DO I HAVE TO PAY? I WANT THE FREE EDITION
The information that you can enter in Free Edition is pretty limited now. Thanks to the new tax laws that began for 2018 returns, there are no more simple Form 1040EZ or 1040A's. Everything goes on a Form 1040 that has three extra "schedules" with it, and if you need any of those schedules, you are not able to use the Free Edition. Using the standard deduction instead of itemizing does NOT mean you will not need any of those schedules.https://ttlc.intuit.com/questions/4511011-what-happened-to-the-1040a-and-1040ez
If you qualify to use it, there is another full-featured free version of the software:
Try Free File:
You qualify if your income was $36,000 or less, or $69,000 or less if active duty military, or if you qualify for Earned Income Credit
Note: If you do not qualify to use Free File then you will have to upgrade to Deluxe or higher in the paid versions of the software.
