Valuation Date. Valuation Date is the date upon which the value of your property is based. In most communities, Valuation Date is July 1 of the prior year (but this date can also vary). For example, assessments on the 2022 assessment roll (typically made public on May 1, 2023) were based on the value of property as of July 1, 2021.
The lag between Valuation Date and Tentative Roll Date enables assessors and taxpayers to use all available sales before and after the Valuation Date to estimate the value of property.
Taxable Status Date and Valuation Date. As noted above, the assessments published on the tentative and final assessment rolls are:
- based on the value of the property on Valuation Date, and
- based on the property's condition and ownership as of Taxable Status Date.
- Your home was destroyed by fire in February, 2022 leaving only a vacant lot.
- Because the property burned down prior to Taxable Status Date, your 2022 assessment was based on the vacant lot only.
- Your 2022 assessment was based on the value of your vacant lot on July 1, 2021 (Valuation Date).
- Your September 2022 school taxes and January 2023 town and county taxes are based on the value of the vacant lot.
- Your home burned down on March 15, 2022 leaving only a vacant lot.
- Because the property burned down after Taxable Status Date, your 2022 assessment was based on your property with your home intact.
- Your 2022 assessment was based on the value of your home on July 1, 2021 (Valuation Date).
- Your September 2022 school taxes and January 2023 town and county taxes are based on the value of your home.
Local budget dates
If you are concerned with the amount of property taxes being collected in your community, you may wish to be involved with the local budgeting processes. There are public meetings you can attend and voice your opinion, and you also have the opportunity to vote on your school budget.
For school district taxes, in addition to voting on the budget, you can attend budget meetings. Generally, the budget meetings are held in the spring through early April.
For municipal and county taxes, budget meetings are typically held in the fall through mid-November. Special districts (fire districts, sewer districts, etc.) also hold public meetings, but the dates vary. Contact the district for more information.
