FAQ

  • Is my property information available online?

    Yes. To access Beacon, click here

  • If I split a property, when will I be assessed and when will I pay taxes on the two pieces separately?

    If you split a property, for example parcel A, before November 1, 2025, into parcel B and C, your assessment value would be only for parcel A and would be payable in 2026. Your 2026 assessment would be split between parcel B and C for taxes payable in 2027.

  • If my new home is not complete by November 1, 2025 when will it be assessed?

    If your home is 60% complete on November 1, 2025, you will be assessed at 60% of its completed value for your 2026 assessment payable in 2027. If the home is then completed by November 1, 2026 you will be assessed at full and true market value for the 2027 assessment for taxes payable in 2028.

  • If I build a house that is completed on or before November 1, 2025, when do I pay taxes?

    If your home is complete before November 1, 2025, we will be out to view the home in 2025. The value we arrive at will be on your 2026 assessment notice which you will receive around March 1, 2026. Then in 2027, you will receive a tax notice from the Treasurer for your 2026 assessment.
