For Mercer County, use WIPP for current tax and sewer balances, Mercer County PIP for property record cards and tax information, and the Mercer County records portal for deeds. For Atlantic County, use the township WIPP portal for tax bills and the Tax Assessor-linked assessment-record search for value, ownership and property-card information.
Should I contact the Hamilton Township Tax Collector or Tax Assessor?
Contact the Tax Collector for bills, payments, sewer charges, receipts, interest, delinquent notices, tax-sale payments and lien redemptions. Contact the Tax Assessor for assessed value, ownership records, property record cards, added assessments, deductions, exemptions and assessment appeals.

What should I do if the Hamilton Township tax record is still under the prior owner?
Search by block and lot, property location or prior-owner name and verify the correct property before paying. Mercer County Hamilton says ownership updates can take six to eight weeks after closing. If the owner remains wrong after that period, follow the township and county-record correction route.

Do not estimate the payoff. In Mercer County Hamilton, tax-sale notice payments require certified check, cash or money order and may include sale costs.
