Corporate Tax IDs

When a company changes their Corporate Tax ID during the year, the tax ID that was replaced will no longer exist in the Payroll Corporate Tax Identification table (F069086). The system was designed assuming a one to one correspondence between company number and the Corporate Tax ID.

When the records are updated in the Tax History table (F06136), they are updated with the tax identification numbers that are currently in the F069086 table for the company. When a company changes their Corporate Tax ID, a new set of history records are created in the F06136 table with the new Corporate Tax ID, but with the same company number. TAXX is a key to the F06136 table. If you run the integrity reports for an employee when there is a change in company's Corporate Tax ID, then the Corporate Tax ID does not match and the system throws errors on all the records with the previous Corporate Tax IDs.

Because the company's current Corporate Tax IDs in the F069086 table are not the same as in the F06136 table; when you run the integrity reports in update mode, the records in the F06136 table will be merged into a single record per tax type for that company with the new or updated Corporate Tax ID from the F069086 table. If you ignore these errors and run the year-end build process for the employee, the year-end build cannot accurately match up the state wages from history to the Corporate Tax ID.

The Employee State/Local Control table (F07831) (state information) has fields for both TAXX (Federal A tax ID), and TAXS (state tax ID). Even though the F06136 table might contain the previous tax IDs on the tax history records (if the integrity reports were not run in update mode), when the year-end build process is run, the system will not know which Federal A tax ID was available at the time the state wages were under the tax ID on the state history record. Therefore, if there is a change in the Corporate Tax ID, you must also change the company number. If you want to change the Corporate Tax ID for the same company number, then you must run the year-end build after the last payroll of the year, and prior to changing the corporate tax ID in the Corporate Tax IDs table.
