What can the Suffolk County Assessor's Office do for me?
The Suffolk County Tax Assessor's Office oversees the appraisal and assessment of properties as well as the billing and collection of property taxes for all taxable real estate located in Suffolk County.

Submitting a Suffolk County property tax appeal
If you believe that your house has been unfairly overappraised (i.e. appraised at a value higher than the true market value of the property), you can attempt to get your home re-appraised at a lower value by contacting the Assessor's Office to submit a property tax appeal.
You will have to submit a form describing your property and sufficient proof that it is overassessed, including valuations of similar homes nearby as evidence. If your appeal is accepted, your home assessment (and property taxes) will be lowered as a result.
If you would like to appeal your property, call the Suffolk County Assessor's Office at (631) 852 1551 and ask for a property tax appeal form. Keep in mind that property tax appeals are generally only accepted in a 1-3 month window each year.
For more information and example appeals, see how to appeal your property taxes.
