New Jersey's Dual Appeal System

• Timeline: 3-9 months
• Good for: Smaller reductions

Option 2: New Jersey Tax Court

• Deadline: April 1 or May 1
• Filing fee: $150 (if seeking >$20k reduction)
• Timeline: 12-24 months
• Good for: Larger reductions

You can only choose ONE path per year.

Critical: New Jersey's Strict Deadlines

NJ Tax Court Rule 8:4 states no deadline extensions except for:

• County failed to mail assessment notice
• Death of property owner
• Active military deployment

"I didn't know" = appeal dismissed.

When to File Tax Court vs County Board

File with County Board if:

• Seeking <15% reduction
• Want quicker resolution
• Prefer informal process
• Limited evidence

File with Tax Court if:

• Seeking >15% reduction
• Have strong evidence
• Can wait for resolution
• Complex property issues

Cost of Missing NJ's Deadline
