In Oracle Payroll Cloud, a tax reporting unit (TRU) is created as part of the payroll statutory unit (PSU) setup. When a legal entity is identified as a PSU, the application automatically transfers its associated legal reporting units (LRUs) to HCM as TRUs (Option A). This ensures tax reporting aligns with the legislative requirements of the PSU. Option B is incorrect, as there's no optional step to designate the PSU as a TRU-it's automatic. Option C (directly identifying a legal entity as a TRU) bypasses the PSU linkage, which is not supported. Option D (legal employer) is inaccurate, as TRUs are tied to PSUs, not legal employers. Oracle documentation confirms this automatic transfer process.
