I want to update New EIN for Federal Tax

Good morning, @accounting293. 

Thanks for taking the time to reach out to the QuickBooks Community for support. I hope you're enjoying the day so far. 

Updating your EIN in QuickBooks Online is easy as 1, 2, 3. I've included the steps to make the changes below. 

1. Go to Settings, then Account and settings.
2. Click on Sales, then tap on the Messages section. Update your company name anywhere it appears here.
3. Select Company, then Company name.
   • EIN: Hit EIN and enter your new info.

That's all there is to it. For additional details about this process, check out Change your business name, contact info, or EIN in QuickBooks Online. 

Please let me know if you have any questions or concerns. I'm always here to lend a hand. Take care!
