Between working full time, raising a family and catching up with all your streaming shows, you’re busy. So busy, in fact, that the additional burden of paying your taxes feels overwhelming. You might even wonder what would happen if you just didn’t file your taxes this year.

You figure you won’t end up in prison like Al Capone, but what’s the worst that could actually happen? Confident that I won’t end up an accomplice after the fact, I decided to help you out by consulting ChatGPT.

I asked the AI what would happen if you didn’t file your taxes. Spoiler alert: It’s not good.

While armed agents aren’t going to break down your door if you miss the tax deadline, ChatGPT cautioned that the IRS will charge a failure-to-file penalty.

That penalty is typically 5% of the unpaid tax for each month (or partial month) your return is late, up to a maximum of 25%. Interest also accrues on top of the penalty and compounds daily.

“This makes the total grow quickly, even if the original amount wasn’t huge,” wrote the AI.

It’s also worth noting that if you both fail to file and fail to pay, the IRS generally reduces the failure-to-file penalty slightly — but the combined penalties can still add up fast.

To better understand what the penalty could look like, you might want to peruse the page on the IRS website devoted to the failure-to-file penalty. It’s sobering reading.

As if this information didn’t scare you enough, the AI decided to compound your worries.

“If you don’t file, the IRS can create a Substitute for Return (SFR) using income data they have,” it wrote. “These returns don’t include deductions or credits you might qualify for, often resulting in a higher tax bill than necessary.”



OK, that is really alarming. But if you’re not persuaded that you absolutely must file your taxes, let ChatGPT continue.

Over time, unpaid taxes can have a disastrous impact on your finances. Your wages could be garnished. There could be levies on your bank account or federal tax liens placed on your property.

This is a pretty bleak picture. But it doesn’t have to be your future.

“These measures typically happen after repeated notices are ignored,” ChatGPT said.

In other words, the IRS usually starts with letters — but continued inaction can lead to aggressive collection efforts.

Even if you’re not hit with harsh penalties, you could still face financial consequences for not filing your taxes.

“If you’re owed a refund, there’s no penalty — but there is a deadline,” it wrote. “You have three years to claim it, after which the government keeps the money. You may also miss out on valuable credits.”

Not to sound like your scolding parent, but ChatGPT wants you to know that not paying your taxes can have long-term — and potentially devastating — consequences for your personal finances. Beyond that, it can affect major life choices.

The AI shared that missing tax returns can make it harder to:

  • Qualify for loans or mortgages

  • Apply for financial aid

  • Verify income for renting or government benefits

“In short, it can quietly limit your financial options beyond just taxes,” ChatGPT said.



That might be the most unsettling consequence of all.

Yeah, a lot can happen if you don’t file your taxes — and none of it is good. Penalties grow quickly, refunds can disappear and the IRS has more tools at its disposal than many people realize.

If you’re feeling overwhelmed by the prospect of paying your taxes, remember that filing — even if you can’t pay right away — is almost always better than doing nothing. You can also turn to a tax preparer or enrolled agent you trust to help you explore options like payment plans or penalty relief.
