Credit Karma Tax review

The popular credit monitoring site lets you file for free, but it’s not available in all states.

Credit Karma Tax offers a straightforward way to file your taxes for free, even if you’re self-employed or have several deductions. But you need a Credit Karma account and if you live in one of the 10 states where this service isn’t available, or you’re hoping for hands-on support, you’ll want to look elsewhere.

In June 2021, Credit Karma Tax became part of Cash App, which is owned by the payment processor Square. The software will get a new name and a new home before the 2021 tax season starts, but nothing will change before July 15, 2021. When the service does relaunch, it will still be free and include many if not all of the same features as the current interation.

Expert review

Credit Karma Tax is best if your taxes are uncomplicated and if you’re already familiar with the filing process. Credit Karma Tax is free and offers maximum refund guarantees and free audit defense. Plus, as far as free online tax software goes, Credit Karma Tax is also able to offer calculations guarantees — yet only up to $1,000.

But if you’re hoping for a lot of hand-holding during the application process, you’re limited to its 24/7 online chat. Plus, you’re only eligible to use Credit Karma Tax if you have a Credit Karma account and if you live in Alaska, Florida, Montana, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington or Wyoming.

How much does Credit Karma Tax cost?

Credit Karma Tax is completely free for all users. There’s no cost to file your state or federal return, no matter how simple or complex your tax situation is.

Credit Karma Tax pros

Credit Karma Tax offers several attractive features, including the ability to import previous years’ returns from TaxAct, TurboTax and H&R Block.

  • Completely free. There’s no cost to file your state or federal return with Credit Karma Tax.
  • Max refund guarantee. If you file an amended return using a different online service and receive a bigger refund or find out you owe less, Credit Karma will pay you up to $100 to cover the difference.
  • Streamlined process. Credit Karma Tax will only show you sections you need to complete based on your tax situation. You can also upload your W-2 by taking a photo of it.
  • Accurate calculations guarantee. If the IRS or your state tax authority penalizes you due to a calculation error, Credit Karma will reimburse you up to $1,000. Some other tax programs offer greater guarantees, including Tax Act, which will reimburse up to $100,000 for any penalties and interest you’re required to pay due to miscalculations caused by its software.
  • Free audit defense. Credit Karma automatically checks your return for accuracy and provides an Audit Defense service for free.


Credit Karma Tax also has a few shortcomings to keep in mind before signing up.

  • Not available in all states or if you recently moved. You can’t use Credit Karma to file taxes in Alaska, Florida, Montana, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington or Wyoming. It also doesn’t support income from multiple states, so you’ll need to look for another software if you moved in the middle of last year.
  • Credit Karma account required. You must open a Credit Karma account to use Credit Karma Tax.
  • Can’t import investment data. There’s no way to import investment data into Credit Karma Tax easily.
  • Not for complicated taxes. Credit Karma Tax contains the most common tax forms, but it’s missing forms you may need if your taxes are unusually complicated. Plus, unlike other online tax software, you won’t get a step-by-step walkthrough on how to file your taxes. You’re limited to a 24/7 chat if you need support.
  • Can’t skip around. Credit Karma tax requires you to complete one form before proceeding to the next one. Other services let you skip sections you’re not ready to fill out.

If you want more tax filing support or you have complicated taxes, you’ll want to keep looking. As always, compare your options when considering an online tax software.
