Thanks for bringing this to my attention, @nancysakakura.

If your company is linked to e-services, you may need to turn this off first before updating your legal business name. After updating the info, please turn it on again and send us a new authorization form.

The details and steps are outlined in this article: Update your business info in online payroll.

I'm here to get you moving in the right direction, so let me know how it goes after performing the steps. I'm always around if you need help. Have a great day!
