Tax Collection

The Tax Office is the major source of revenue for the Town of Hamden, collecting more than $184 million dollars in taxes for the 2018 to 2019 fiscal year. This represents a current grand list collection rate of 99.5%. The department also collected over $2 million dollars in delinquent taxes and over $1 million in interest charges.

A consistently high collection rate is the key to fiscal stability for the Town and remains the number one priority of the Tax Collector. Balancing the need to maintain a high rate of collection with the sensitivity necessary to deal with individual taxpayer issues, especially in this difficult economy, is an integral function of the department.

The Tax Department takes pride in providing taxpayers with prompt, courteous, professional service, while at the same time maintaining an extremely high rate of collection.
