Need More Time to File Your Utah Taxes?

Running behind on your Utah state taxes? Don’t sweat it. Whether life got hectic or you’re just a master procrastinator (we won’t judge), Utah makes it surprisingly easy to get more time to file your return. Here’s everything you need to know about getting a Utah state tax extension.

Does Utah Offer a State Tax Extension?

Yes! Utah grants an automatic six-month extension to file your state income tax return. No paperwork, no requests, and no excuses necessary. But there’s a catch: it’s an extension to file, not to pay. If you owe Utah taxes, they’re still due by the original deadline (usually April 15th).

How the Utah Tax Extension Works

Utah doesn’t require you to submit a special form to get more time to file. The state automatically grants an extension. However, you must still pay 90% or more of your Utah tax liabilities by the April deadline to avoid insufficient prepayment penalties.

Utah State Tax Extension Deadline

The Utah extension gives you until October 15th to file your return. But remember:

Payment is still due by April 15th.

If you miss that date and owe taxes, you could rack up interest and late payment penalties—and no one likes surprise fees.

How to Pay Your Utah Taxes with an Extension

Even if you're not ready to file, you must pay your tax liabilities to avoid penalties. Utah offers several payment options:

What If You Owe Nothing?

If you don’t owe Utah any tax, you're off the hook. You can file your return at any time before the October deadline without incurring penalties. Just don’t forget about it completely—October creeps up fast.

Federal Extension vs. Utah Extension

Here’s the lowdown: Utah gives you an automatic extension to file—no extra forms required, even if you didn’t request a federal extension. Yep, you read that right. Whether or not you filed IRS Form 4868, Utah lets you breathe a little easier come tax season.

Utah Tax Penalties and Interest

Here’s the not-so-fun part: Utah charges you interest and penalties if you owe taxes and don’t pay by April 15th.

Interest: Charged on unpaid balances from the due date until paid. Currently, the interest rate is 6%.

Insufficient Prepayment Penalty

If your prepayment is less than 90% of your tax liabilities for the current tax year, you will incur an insufficient prepayment penalty.

  • 2% per month (Computed daily until you file your return or the extension expires)

Late Payment Penalty

Behind on your payment? Here’s what you’re looking at:

  • 2% penalty if you're 1–5 days late
  • 5% if it's 6–15 days
  • 10% if you're 16 days or more past due

Late Filing Penalty

Filed your return later than October 15th? Here’s how the penalty stacks up:

  • 2% if you're 90–95 days late
  • 5% if it's 96–105 days
  • 10% if you’re 106+ days late

Note: You face Late Payment and Late Filing Penalties if you filed later than October 15th. However, the Insufficient Prepayment Penalty will not apply.

Utah Tax Facts

Getting a grip on Utah’s tax scene can make filing—or asking for more time—much easier. Here’s the quick-and-dirty rundown:

  • Flat Income Tax Rate: 4.55% across the board
  • Total Income Tax Collected (2023): About $6.43 billion (yep, that’s a lot of zeros)
  • E-Filing Popularity: More than 93% of Utahns file online—because it's way easier
  • Top Filing Mistake: Not paying enough in estimated taxes or missing that April 15 deadline
  • Why It Matters: Over 40% of Utah’s general fund depends on income taxes, so they’re serious about getting it right.

Timely and accurate filing helps avoid penalties. Additionally, your tax dollars support essential services in the state, including infrastructure and education.

Common Questions About Utah Tax Extensions

Can I e-file a Utah state extension?

You don’t need to! Utah doesn’t require a formal extension request. Your extension is automatic.

Do I need to attach anything to my Utah return later?

None. Utah automatically grants a tax filing extension for six months.

I’m getting a refund. Do I still need an extension?

Nope. If the state owes you money, you won’t face penalties for filing late. However, you should still file by October 15 to claim your refund.

What if I miss the October 15th deadline?

If you fail to file by October 15th and owe money to the state, you get hit with failure to file and failure to pay penalties, plus interest. The sooner you file, the better.
