Yes — the Patna Municipal Corporation (PMC) property tax assessment can be challenged, and there is a formal mechanism for doing so that many Patna property owners are unaware of. An assessment based on incorrect parameters — wrong area, wrong use classification, wrong road category — is not only challengeable but frequently revised in the owner's favour when the right procedure is followed.

Property tax in Patna is levied by the PMC under the Bihar Municipal Act 2007 and the Patna Municipal Corporation Act 1951, assessed on the annual value of the property using parameters including the property's location (determined by road category), its type (residential, commercial, industrial), its built-up area, and a tax multiplication factor. The PMC revised road classifications for Patna properties and issued a new Tax Multiplication Factor gazette notification in 2025, which has affected assessments across the city. If your assessment has increased substantially under the revised parameters, or if you believe the underlying data (area, road category, use type) is incorrect, that is a valid ground for challenge.

The formal challenge is filed as an objection or appeal before the PMC's Assessment Appeal Authority, within the period prescribed from the date of the assessment notice or the demand. You must identify specifically what is wrong: if the PMC has recorded a larger built-up area than actually exists, submit measurement evidence and building plans; if the road category assigned to your property has been reclassified incorrectly, show the correct road classification; if residential premises have been assessed at commercial rates, submit evidence of actual use. The PMC tax portal at pmcptax.bihar.gov.in allows you to view your current assessment details and your Property Identification Number (PID), which is the starting point for understanding the basis of your assessment. If the PMC's own appeal process does not produce a fair result, the matter can be escalated to the civil court through a suit challenging the assessment, or — where the PMC has acted beyond its statutory powers or violated the prescribed procedure — a writ petition before the Patna High Court. The property and municipal law advocates at the Patna panel of Aapka Legal Advice can review your PMC assessment notice, identify any errors, and file the formal objection with supporting evidence.

Keep paying your tax on time while the challenge is pending — non-payment during the appeal period attracts penalty and interest that compounds the problem you are already trying to
