How to appeal your property assessment in New Brunswick
In New Brunswick, Service New Brunswick assesses every property at its value on January 1 of the previous year and mails notices in January.

Tips
- Thirty days is short. Start with SNB's online property information and check the facts (size, finish, outbuildings) before the window closes.
- Lenders don't use your assessment for a refinance; for borrowing, see the equity calculator.
Evidence wins appeals: sales of similar homes near the valuation date, similar homes' assessments, and corrections to the facts on your notice.
