Warren County Property Tax Appeal, New Jersey

Step 1: Review your assessment notice received in mid-April and compare your assessed value to recent comparable sales in your area. New Jersey assesses property at 100% of market value, so if comparable homes sold for less than your assessed value, you may have grounds for appeal.

Step 2: Gather evidence including recent comparable sales (within the last 6-12 months), property condition documentation, photographs showing defects or needed repairs, appraisals, and cost estimates for necessary repairs. Complete Form A-1 Comp. Sale for each comparable property.

Step 3: File your appeal by the deadline using Form A-1 (Petition of Appeal). You can file online at njappealonline.com, by mail, or in person at the Warren County Board of Taxation, 202 Mansfield Street, Belvidere, NJ 07823. The filing fee is $25.

Step 4: Attend your hearing before the Warren County Board of Taxation, typically scheduled between late April and early June. You'll have 5-15 minutes to present your evidence to the Board members, who will review comparable sales, property conditions, and other documentation you provide.

Step 5: Receive the Board's written decision within 2-4 weeks of your hearing. If your appeal is successful, your property will be reassessed at a lower valuation and your Warren County property taxes will be lowered accordingly.

Step 6: If the County Board's decision is unsatisfactory, you may appeal to the New Jersey Tax Court within 45 days of the Board's judgment. For properties assessed over $1,000,000, you have the option to file directly with Tax Court initially.

Step 7: If no further administrative appeals can be made and you remain unsatisfied, you can appeal your Warren County tax assessment in the New Jersey Appellate Division court system.
