What is the penalty for filing late?
If you do not file a form of list for the fiscal year, the Assessors cannot grant an abatement for overvaluation for that year. If you file late, the Assessors can only grant an abatement if you show a reasonable excuse for the late filing or the tax assessed is more than 150% of the amount that would have been assessed if the list had been timely filed. In that case, only the amount over that percentage can be abated. You can avoid this penalty by filing on time.
