Filing Deadline For AISE Statement In Nassau County Is April 1, 2022

Nassau County requires owners of class 4 “income-producing property” and property that is owner-occupied, under construction, and/or sold or purchased during each calendar year to file an Annual Survey of Income and Expense (ASIE Statement) on each applicable property. As a reminder, the filing deadline on your ASIE Statement for the 2021 year is April 1, 2022.

Currently, property owners are able to view the status of their 2016, 2017, 2018, 2019, and 2020 filings on the ASIE filing portals. Property owners are able to file if they have not done so. Property owners are unable to check the status for 2015, 2014, or 2013 filings at this time. We strongly recommend each property owner check the status of their filings, and file if you have not already done so.

The filing is imposed upon all owners of commercial property in Nassau County and is independent of the tax appeals you have commenced. HK cannot access the forms and we cannot file the forms for our clients, but we ask that you provide us with a copy so that we are aware of what information the County has been provided on your property.

If you believe the status of your filing is inaccurate, please contact the ASIE Department at:

(516) 571-0996
Department of Assessment
240 Old Country Road – 4th Floor
Mineola, NY 11501
Attn: ASIE Compliance

As a reminder, separate statements must be filed for each parcel, except that a consolidated statement may be filed where one or more tax lots are:

(1) operated together as an economic unit (or otherwise related for valuation purposes), and/or
(2) under common ownership and are contiguous, or within the same, or an adjacent tax block.

Additionally, Nassau County requires that a rent roll be filed with the statement where applicable. Please note that the law as it is currently written imposes penalties for failing to file, or filing improperly, among other defaults. The ASIE Statement MUST be filed electronically via the Nassau County website. The electronic filing forms for all years and instructions are available on the Nassau County website and may also be accessed at this time at
