Understanding Tax History Integrity

Each time that you run the final update for a payroll cycle, the system creates payroll history records and stores them in history tables. The two types of history records are:

• Detail records

• Summary records

Detail history records contain each tax type, pay type, deduction, benefit, and accrual that the system calculates for each payment. The system stores these records in detail history tables.

After the system stores records in the detail history tables, it totals and summarizes the information in these tables and creates summary history records. The system then writes the summary history records to the corresponding summary history tables. The system uses the summary history tables to retrieve tax and earnings information for government reports and year-end forms. Using summary history tables to report tax and earnings information reduces processing time.
