Yes, you can appeal your property tax valuation if you believe it does not accurately reflect your property’s market value. The appeal must be made within a specific timeframe after receiving your valuation notice from the Revenue. The process involves submitting a formal appeal online through the Revenue’s LPT portal, where you will need to provide evidence supporting your claim for a different valuation, such as market data or a professional valuation report. An independent adjudicator will review your submission and make a decision.
