Vacant Unit Tax Drop-In Clinic

Vacant Unit Tax Declaration Period Now Open for 2025

All Residential Property Owners are required to submit a mandatory occupancy declaration for the 2025 tax year including your principal residence. A property’s occupancy may change year-over-year, an annual declaration ensures the City has accurate information about how residential properties are being used.

• Complete your residential Vacant Unit Tax Declaration by April 15, 2026.
• Late Declarations will be accepted from April 16 to May 15, 2026 with a Late Declaration Fee of $250.

The City of Hamilton is offering in-person, drop-in clinics in Senior Centres across Hamilton, where staff will provide personal assistance to help residential property owners complete their annual Vacant Unit Tax declaration accurately and on time.

No reservations are required. Residential property owners just need to bring their Notice to Declare Letter or most recent property tax bill, which contains the roll number and access code needed to complete their declaration.
