Property Income and Expense Return (PIER) 

Many of the property types listed above are assessed according to their income generating potential.  In order to accurately assess these properties, MPAC requires property owners to file their property income and expense information.  This information is requested annually through our Property Income and Expense Return (PIER) program. A PIER contains the documentation of rental, income and expense information for your property. 

It is important to file your property income and expense information each year to support our analysis of the rental, income and expense trends for your property, which contributes to accurate property assessments. 

If you do not receive a letter but believe you should have, please contact us.
