Cut Your Property Taxes: A Simple Guide to Filing a Hamilton County BOR Appeal
Property owners have the right to challenge their property’s assessed value through the Board of Revision (BOR). This process might reduce your property tax burden if think your property is overvalued. Recent higher than normal property assessments have prompted legislation considerations, such as HB 124, as a method to balance fair valuation increases. It is best investor practice to check your property valuations annually to ensure they align with the market rates.
If you find that your assessment needs to be challenged, we have provided a complete guide and checklist to ensure your request is accurate and timely.
