ASIE Frequently Asked Questions



The confidential income and expense data collected in the ASIE is used to improve assessed values of all properties similar to yours. Your ASIE income and expense data is never used directly to value your property. Your data is added to all the data collected from the ASIE plus the data the Department of Assessment maintains on the physical attributes of all commercial properties to enrich statistical studies used to value all types of commercial property across Nassau County.

YES. 100% owner occupied properties are not exempt from filing the ASIE 2018; however, you will not be asked any questions about your income or your expenses.
Properties change hands, owner occupants become landlords. If your property were to become occupied by someone other than the owner, we need to know that and collect the income and expense to add to our database.
This means someone else has started or completed a filing for this parcel. Please check with your accountant, attorney, property manager or any other party who may have filed on your behalf and resolve this conflict.
This means the parcel you have input is not a liable filer. Check that you are entering your section, block and lot correctly. Take your section, block, and lot from your ASIE announcement letter. As a double check you can also validate your parcel by street address. Additionally, check the class of the parcel. As of this writing only class 4 properties are required to file the ASIE 2018. It may also be that this lot is a parking lot; if that is the case please enter the improved lot (the one with the building) and add this lot as a contiguous lot.
Use the "Forgot Password" tool on the ASIE login page. On the forgot password screen you'll be asked to supply the email address you started your account with. You will receive an e-mail with a link to re-set your password. If you didn't receive the reset password in your inbox, please check your spam folder.

Yes, you must file for ASIE regardless of the profitability of the commercial property.
We don’t ask for your Real Estate Taxes because we already have that data and we use it in building our valuation model.
Yes. We won't ask you about your income and expense but, the sale date and sale price is important to us. After you supply that information and any change of mailing address you will be asked to certify your statements and that's it.
Yes. Vacancy data is very important when building statistical models to assess commercial real estate. Be sure to indicate your vacancy in the appropriate field.
This is analogous to depreciation of equipment on a tax return. For the purposes of the ASIE reserves for replacement represents the amortized cost of short lived building components that will wear out before the building, for example: a new roof, resurfacing a parking lot, replacement of HVAC systems, upgrading network connectivity. If you replaced a roof for $20,000 and you anticipate it has a 15-year life, then 20,000 divided 15 = $1,333 (rounded) is the figure you 'd put in the reserves for replacement. Try to remember that figure for use in future ASIEs. Do not include painting, tape and spackle, changing of locks, new light fixtures, or any routine maintenance items in the reserve for replacement.
Your mortgage expense is the product of negotiation between you and your lender. It is not a reflection of your property's ability to earn income, nor is it an expense generated by the condition, location, age, maintenance or quality of the improvements.
A contiguous lot is a lot adjacent or in close proximity to the Primary Lot you started your filing with. A contiguous lot is part of the same real estate business entity and possesses an interdependent relationship with the primary lot such that both lots are more valuable because of that relationship. Examples would be: A lot line running through an office building, a retail establishment on one lot and it's parking lot on an adjacent lot, an industrial building with employee parking on a lot across the street. Please put in all the lots associated with that particular real estate business.
It is rent collected for the use of land under a building built by someone else. Typically, these are long term leases of 99 years. It might also mean rent collected for the use of land for outdoor storage.
