TAGS and Projects - how do I allocate to a journal

Hello there, @colnaghi-com.

Able to allocate tags to Journal is currently not an option for QuickBooks Online (QBO). And as for the project, you can assign a journal line to a customer/project by selecting them/it under the 'Name' column.

I can see how the feature you're looking for would benefit and empower your business. In the meantime, I recommend sending this request straight to our product engineers through feedback. 

To send feedback, follow the below steps:

1. Go to the Gear icon at the top.
2. Select Feedback.
3. Enter your comments or product suggestions. 
4. Then select Next to submit feedback.

In the meantime, let me share some resources that you can browse and use as a reference in managing and navigating your QuickBooks account.
