Whats the New Jersy Law on retaining data for coperations?

No state has an across-the-board data retention law. As noted in response to the previous question about California, all states permit business records to be maintained indefinitely. Thus, recordkeeping requirements generally focus on the appropriate minimum retention period, which requires an inquiry into the purpose of maintaining the document and the statute of limitations for asserting claims to which the documents might provide a defense. For example, the statute of limitations on most tax claims is three years; therefore, most tax-related documents need to be retained only for three years (or enough past that to allow for any audit or claim to be learned of by the taxpayer).
