Prepayment Requirements

An extension allows extra time to file a return, not to pay your taxes. To avoid an extension penalty, you must do ONE of the following by April 15:

• Prepay 90 percent of your 2008 tax (through withholding, applying a refund from the previous year, or direct payments; OR
• Prepay an amount equal to 100 percent of your 2007 tax.
• Prepay 90 percent of the 2008 tax due if you did not file a return or had zero tax in 2007.

Notes

1. Interest will accrue during the extension period on any tax that was not prepaid by April 15.
2. To avoid a late filing penalty, you must pay all tax, interest, and any extension penalty the same day you file your return.
3. The late filing penalty will be waived if:
   • You are a Utah resident stationed outside the US for military service and
   • You file your return by your discharge date or the 15th of the fourth month after you return to the US (whichever is earlier)
   Interest will accrue on any unpaid tax from the original due date until the tax is paid. See combat zone relief.

Extension Penalty

If you don't meet the prepayment requirements (above) by the original due date, an extension penalty will be added. This penalty is assessed at 2 percent per month until the date the return is filed. The penalty is calculated using this formula:

(unpaid tax) x .24 x (number of days) ÷ 365
