How to Appeal Your Property Tax Bill

Learn the step-by-step process to challenge your property tax assessment and potentially lower your annual tax bill.

  1. Check your assessment notice for errors. Review your property tax bill for basic mistakes like wrong square footage, number of bedrooms, or property features. Look for errors in your home's description — assessors sometimes list a garage you don't have or miss structural problems that affect value. These simple mistakes are the easiest wins in an appeal.
  2. Research comparable home values in your area. Find 3-5 similar homes within half a mile that sold in the past 6-12 months. Look for houses with similar square footage, age, and features. If your assessed value is 10% or more above recent comparable sales, you have grounds for an appeal.
  3. Document problems that lower your home's value. Take photos of any issues the assessor might have missed — foundation cracks, outdated electrical, plumbing problems, or needed roof repairs. Note if your home backs up to a highway, power lines, or other features that reduce market value. These factors should lower your assessment compared to similar homes without these issues.
  4. File your appeal before the deadline. Submit your appeal to your local assessment board or tax authority — the process varies by location. Include your evidence packet with comparable sales, photos of problems, and a letter explaining why your assessment is too high. Most jurisdictions require appeals within 30-60 days of your assessment notice, so don't wait.
  5. Prepare for your hearing. Present your case clearly at the hearing — stick to facts and comparable data rather than complaints about high taxes in general. Bring printed copies of your evidence for board members. Be ready to explain why your home's market value is lower than the assessed value, not why you think taxes are unfair.
  6. Consider hiring a professional for complex cases. Property tax consultants typically charge 25-50% of your first year's tax savings if they win your case. This makes sense for expensive properties or complex situations, but most homeowners can handle straightforward appeals themselves. Only pay a professional if your potential savings exceed $1,000 annually.
