Reminder from Cullen and Dykman Tax Certiorari department:
All commercial property owners in Nassau county must file online their annual survey of income and expenses (“ASIE”) by April 1, 2025. A 60 day extension is possible if “good cause” is established.
You can access your online ASIE forms and extension applications here:
Online ASIE Forms | Nassau County, NY - Official Website
This applies to both owner-occupied and income producing commercial properties. Owner-occupied properties do not have to report income but must file the appropriate form nonetheless. Multi-family operators (rental apartment buildings, cooperatives and condominiums of more than 6 units) are exempt from filing an ASIE form.
The ASIE reporting requirement has nothing to do with whether or not a property tax appeal is filed.
The firm cannot file for you but is happy to answer any questions you may have.
