After a new tax ID has been received, please send all documentation showing proof of the tax ID obtained to the Tax Department by submitting a Tax Ticket. Choose "Need to Add Tax Jurisdiction/Obtained Tax ID" from the ticket reason drop down. It's best practice to add new tax ID's before processing payment for employees within the jurisdiction.
