Tax Lien Warning

⛔ Texas Attorney Fee Warning: After July 1, delinquent property taxes are referred to a collection attorney. An additional 15–20% attorney fee is added on top of your penalty and interest. On a $5,000 tax bill, this adds $750–$1,000 instantly. Pay before July 1 to avoid this.

Choose the correct account boxUse Tax Account Information for property tax. Use Utility Account Information for the Hamilton Township sewer account.
Search with one field onlyFor taxes, enter property location, block and lot, or owner name in only one search box. For sewer, use property location, Utility Account ID or owner name.
Open the correct propertyCompare location, owner, block, lot, qualifier, tax quarter, sewer account and displayed payment history. New owners may need to search the prior owner’s name.
Select Make a PaymentChoose the intended tax quarter, full available amount or sewer charge. Do not assume a payment to the tax account covers sewer.
Complete every payment screenEnter the payment information, continue through validation, select Process Payment, then select Finish. Leaving before Finish can prevent completion.
Check for Payment PendingThe township says the account should display “payment pending” in red after successful submission. Save the confirmation and check the bank/card record.

Atlantic County Hamilton tax sale and lien-redemption rules

Annual tax sale

The township says delinquent-property tax sale is normally held in March or April and advertised for four weeks. A written request for the delinquent-property list may be made in February with a self-addressed stamped envelope.

Lien redemption

Redemption must occur through the Tax Collector. Payment must be certified check or money order, only a party of interest may redeem, and the office needs the date the payment will arrive to calculate the figure.

Do not use the WIPP current-date interest for a lien redemption. Call 609-625-2151 and request the amount through the intended received date.
