If you need to submit payments or document, there are two drop boxes outside our office main entrance.  One for Tax Claim Bureau payments, and the second (black box) is for Tax Assessment related documents, including plans and deeds for UPI certification.  If subdivision and/or land development plans for PIN numbers are being submitted but will not fit into the black box, deliver these documents to the security guard at our main entrance - with the appropriate department name to which these are to be delivered - as well as your contact information for further instructions.  The contents of these boxes will be reviewed weekly and processed as soon as possible.

The Dauphin County Office of Tax Assessment is primarily responsible for the valuation of real property for ad valorem (at value) tax purposes, including the management of all property characteristic and ownership records. This office does not establish the real estate tax levy; it is responsible for the valuation (commonly known as the assessment) of all real property in Dauphin County. Based on those assessments, the County, municipalities, and school districts establish budgets and necessary millage rates to generate revenue, apply those millage rates to individual property assessments, thereby producing individual property tax levies. The Office of Tax Assessment also administers the following programs:

Homestead and Farmstead Exclusion Program (Act 50 & Act 1)
     Information about the Homestead and Farmstead Exclusion Program
     Homestead/Farmstead Exclusion Application

Clean and Green Preferential Assessment Program (Act 319, as amended)
     Information about the Clean and Green program
     Clean and Green Application  (New filing deadline will be October 15, 2020 effective for January 1, 2021.)

Tax Deferral Program (Act 50)
     This program is not currently available, as there has been no County tax increase since 2005.

This office is further responsible for the production of tax duplicates, resulting in the preparation and delivery of County and municipal real estate tax notices in accordance with contracts with 39 municipalities within Dauphin County.
