Switching to the STAR Credit
Property owners who wish to switch to the STAR credit from the STAR exemption, can do so by registering for the STAR credit. (They are not required to "renounce" the exemption.)
For more information about switching to the STAR credit, see:

How to switch to the STAR credit
Property owners with STAR exemptions may wish to stop receiving the exemption for various reasons. They should bear in mind, however, that the decision to give up a STAR exemption is irreversible. This includes property owners who switch to the credit; they cannot switch back to the exemption at a later time.
