If the deed to a property is donated to a non profit youth organization, can the nonprofit request the city of Philadelphia to forgive the back taxes?

I am the legal owner of a nonprofit organization which serves youth at risk of homelessness, juvenile delinquency, truancy etc. Currently, we have been granted daily use of the 2nd floor of a daycare center. A week ago, a local businessman donated a commercial store front to the youth organization. This building however is a distressed property in need of renovations and is behind in taxes. My question to you is can the nonprofit organization get those taxes forgiven by the city of Philadelphia or will the nonprofit be forced to come up with the funds to pay off the taxes? Please help me
