It is not really possible to advise what the notice is about. The IRS has many "campus" locations.
I can advise that the Ogden campus handles the penalties that are assessed. If you are late (reason for the installment being you have not paid and the time is past due) a penalty would be assessed for that .
You would need to get the letter and see what the notice number is ***** the letter.
The fact that it comes from the Ogden Campus could just mean that it is because your business is in MS. The Ogden campus handles many functions for requests made from the following states:
Alabama, Alaska, Arkansas, Arizona, California, Colorado, Hawaii, Idaho, Iowa, Kansas, Louisiana, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Texas, Utah, Washington, Wyoming, or any place outside of the United States
You have to get the letter to know for certain what it means.
