I am finalizing my business taxes can i add a new credit care account details

Hi there, @earleyinsurances. 

Welcome to the Community. Yes you can! I'd be happy to guide you through the whole process of updating your credit card account in QuicKBooks. Though, that only the Master Admin, Company Admin, or Standard with all access rights user can view and edit the details. 

Let me show you how: 

1. Go to Gear icon, and select Account and Settings. 
2. Select Billing & Subscription. 
3. In the top section, you'll see your credit card information beside of Payment method.
4. Click the pencil icon and enter your new card information. 
5. Select Save.
6. Click Done.

Your next charge will come from the new card now that the billing info has been updated. 

Please let me know how it goes by clicking the Reply button. Have a great day!
