Owner-occupied homes on up to one acre are eligible for the homestead deduction. Taxpayers generally may receive only one homestead deduction, which is applied to their primary residence. This deduction consists of the standard homestead deduction (which, in most cases, totals $45,000 or 60% of the homestead assessed value) and the supplemental homestead deduction (which in most cases is calculated at 35% of the value after applying the standard homestead deduction). The Porter County Auditor's Office has a homestead compliance program designed to detect ineligible homestead deductions. Taxpayers who receive homestead deductions for which they are not eligible may be issued a corrected tax bill for the current tax year and are subject to up to three years of back tax payments and penalties, under Indiana law.
