Hi TracyLynno!
Hope you're having a wonderful day! I'm happy to provide details about updating your EIN.
You can update your EIN in your company settings, and in payroll and Payments if you have them. Another option is to subscribe to a new QBO plan to start with the new EIN for tax reporting purposes. You may get insights from an accounting professional on this.
I'm sharing this article with detailed steps to update your EIN in different sections in QuickBooks: Change your business name, contact info, or EIN in QuickBooks Online.
Feel free to comment below if you have additional questions about your EIN. Enjoy your weekend!
