Grok, the artificial intelligence tool developed by xAI, can assist people with their taxes, tech billionaire Elon Musk said in an X post. The discussion began when a social media user suggested people should “doublecheck your taxes with @grok.” The user claimed a friend used Grok alongside TurboTax and saw an increase of $1,400 in their tax refund.
The additional refund amount was almost enough to cover several years of premium subscription costs, the user added.

“Doublecheck your taxes with @grok. A friend had Grok doublecheck TurboTax and it increased her tax refund by $1,400. That covers nearly four years of Grok Premium! Disclaimer: This/Grok is not tax advice so always confirm yourself too,” the user @BurnhamDC wrote.

Responding to the post, Musk wrote, “Grok can help with your taxes,” which brought wider attention to the idea of using the AI tool for financial tasks.

Following Musk's comment, several users shared their own experiences.
One user wrote that they had Grok answer all their questions while filing taxes and help troubleshoot errors that came up during the process. “I had Grok answer all of my questions while doing my taxes and troubleshoot errors I was getting, saving me from upgrading to their more expensive plan. So it saved me money that way as well!”

A separate commenter compared Grok's estimate with that of their certified public accountant (CPA). The user said that in January, before filing taxes, their CPA provided an estimate after reviewing all bank statements.
“Last year, in January, prior to filing, my CPA gave me an estimate of how much my taxes would be (she sees all of my bank statements). I asked @grok what my taxes would be. My CPA overstated by ~$7,000, Grok overstated by ~$200. I gave both the same information in January,” the user wrote.

I asked @grok what my taxes would be.
My CPA overstated by ~$7,000.
Grok overstated by ~$200.
I gave both the same information in January.
At the same time, some users raised concerns about privacy and data security.
One user questioned, “It is safe to share social security numbers, etc?”

Some questioned whether Grok could help them avoid paying taxes. Others asked how the tool could assist without being considered official tax advice.
One user wrote, “How can it help and at the same time not be tax advice? #Grok either knows what it's doing or it doesn't. Which is it?”
Another user humorously remarked, “Will Grok handle your appeal and go into court with you too?”
