Filing Deductions

Property tax deductions can be filed online or in person at the Hamilton County Auditor’s Office.

Recently the Hamilton County Auditor’s Office has partnered with a third party vendor, Tax Management Associates (TMA) to assist with eliminating homestead fraud. Tax Management Associates will be mailing letters to Hamilton County residence whose eligibility for the standard homestead deduction needs further clarification. The Hamilton County Auditor’s Office is working alongside TMA to ensure their high standard of customer service is maintained. Should you receive correspondence from Tax Management Associates please know it is not fraudulent and you will want to respond as requested.
