Cobra Consulting Group, New York's Property Tax Grievance Specialists

for Nassau and Suffolk Counties.

Cobra files your property tax assessment challenge, which is called a grievance. The grievance seeks to have your property assessment reduced. If your assessed value is reduced, you will pay less in taxes because your taxes are based on your assessed value multiplied by the tax rate, whether it’s the county, town or school tax rate.


Since taxes are going up, and other people seek to reduce their assessment, you will pay more in taxes, unless you reduce your assessment.

Taxes are going up at all levels in Nassau and Suffolk Counties. Nassau and Suffolk homeowners can file a grievance once a year, which is your right to challenge the assessment that is set on your home.


The assessed value affects your property taxes and reducing your assessment saves you money.

The Nassau County grievance period ends April 30th, 2021 and the

Suffolk County grievance period ends May 18,2021.

You should not pay more than your fair share of property taxes. Make sure you are fairly assessed by challenging your assessment. There is no cost to challenge. You are protecting your rights and making sure that you do not overpay your taxes. When your neighbors challenge and win a reduction, you pay more.

Protect yourself and file a grievance.

There is no risk. Cobra does all the work. There is no court appearance. There is no home inspection.

There's No Risk!

We Do All The Work

No Court Appearance

No Home Inspection

A challenge is filed with the Assessment Review Commission. Any settlement offer is communicated to the client. Cobra negotiates and leads the process for you. If the Assessment Review Commission does not make a satisfactory offer to reduce your assessment, Cobra will file a small claims assessment review on your behalf, the cost of which

is only $30.


No reduction, no fee. If there is a reduction, Cobra charges the lowest rate in the industry. Cobra charges only 40% of the tax reduction secured through the assessment reduction.

Remember, You Can Only File Once Per Year.
