Each August, the Porter County Auditor's office certifies the net assessed values that are used in the preparation of the following year's budgets and property tax bills. The certified net assessed values (CNAVs) for 2021 show a net assessed value countywide of $10.5 billion. This is an increase of about $627 million in taxable value compared to 2020.
The certified values also show the following:
- Porter County's net taxable real property totaled $10.1 billion, a 6.3% increase over 2020. Personal property totaled $1.48 billion, an overall increase of 6.4%.
- The certified assessed value in TIF districts totaled $886 million, an increase of 5.7%.
- The certified net values increased in 25 taxing districts, decreased in five, and remained unchanged in one other.
The certified NAVs are used in setting the following year's property tax rates. It is important to note that the CNAVs are the values as of the certification date each year. The actual assessed values fluctuate throughout the year, due mainly to appeals and corrections. A chart of how Porter County's CNAVs have changed over the years is shown below.
