How Does Tax Reduction in Nassau County and Suffolk County Work?

Individuals who pay property taxes can appeal for a tax reduction. This group includes:


  • Property owners
  • Tenants required to pay property taxes under a written agreement or lease
  • Purchasers



Local tax authorities will assess only the current assessment roll for grievances. You cannot appeal for tax assessment from prior years. Also, assessment grievances do not cost you nor do they require the services of a lawyer.

Common Questions

  • If I file a tax grievance, will tax officials personally inspect my home?

    Local tax authorities establish the value of your home using a process of estimation with data classified as public information (e.g., recent sales of comparable homes in your neighborhood). With a wealth of information at their disposal, local authorities need not visit your home in case you file a property tax reduction.

  • Should I appeal for a tax grievance only once to receive a fair assessment?

    Even if you’ve successfully grieved your property taxes before, file your grievances yearly due to the steady rise of General and School tax rates. If you fail to protest your assessment, your taxes could increase.

  • Is it wise to sign up with another tax reduction company to get “the best deal?”

    Having more than one tax grievance company in Suffolk Countyand Nassau County to represent you can slow down the process of reducing your taxes. The Assessment Review Commission does not settle cases with multiple representatives involved.
