Utah Code §59-1-401 authorizes the Tax Commission to assess the following penalties on individual income tax:
Penalties are separated by tax type and the date returns are filed or payments are made. Penalties are assessed as follows:
|1 through 5 days||The greater of $20 or 2% of the unpaid tax|
|6 through 15 days||The greater of $20 or 5% of the unpaid tax|
|16 or more days||The greater of $20 or 10% of the unpaid tax|
If a tax due return is not filed by the original due date, or by the extension period due date, a late filing penalty will be assessed.
When a return is filed, all tax, penalty and interest due must be paid. If they are not paid by the original due date, a late payment penalty will be assessed.
If the late filing penalty has been assessed, the late payment penalty will not be assessed until 91 days after the due date of the return. If the return is not filed within the 90 days, both the late filing penalty and the late payment penalty will be assessed.
Utah automatically grants a six-month extension to file income tax returns (not an extension to pay tax due). However, you will receive an extension penalty if you do not meet the following prepayment conditions by the original return due date.
Your prepaid credits (withholding tax, pre-payments, credits, etc.) must equal at least:
The penalty on the unpaid tax is assessed at a rate of 2% per month, calculated on a daily basis, until the date the return is filed. The penalty calculation is:
(unpaid tax) x .24 x (number of days) ÷ 365
The following penalties may apply due to findings during an audit:
See Publication 58, Utah Interest and Penalties for more information, including penalties for other taxes.
If you fail to file an information return, complete a required supporting schedule, or use an approved form, the penalty is $50 for each return or schedule up to a maximum of $1,000.
Utah Code §59-1-402 authorizes the Tax Commission to assess interest. The interest rate for a calendar year of two percentage points above the federal short-term rate is calculated for underpayments, deficiencies, and delinquencies.
For calendar year 2013 (Jan. 1, 2013 - Dec. 31, 2013), the interest rate is 2 percent.
Interest is calculated from the original due date of the return until the tax liability is paid in full. Interest is calculated as follows:
interest = (unpaid tax) x (interest rate) x (number of days) ÷ 365
Note: Payments are applied first to penalties, then to interest, and last to the tax liability. See Rule R861-1A-18.
