QBO - Create invoice with different taxes per line item

Hello there, TPP-DEV. We'll provide a few insights about how sales taxes are calculated in QuickBooks Online (QBO) and encourage you to send feedback or product recommendations to help improve the features and your experience with the platform.

QuickBooks automatically calculates the total tax rate for each sale based on your location, customer's tax status, where you sell and ship, and what you sell. However, you can only use one tax code per invoice and not the per line item. For now, you may want to manually include sales tax, add tax codes as items, or override them on your sales transactions.

On the other hand, we put a value on our customers’ voices and consider them when enhancing the product. Let me help and guide you on how to send your ideas straight to our product engineers.

Thank you for your reply.  But none of the solution (work around) is working for me.

1) Having custom tax rate (10%) : 

         In this case custom tax rate applies to entire subtotal of $700.

         But in my case I want 6% tax on $700 and 4% tax on only $100.

2) Add sales tax code as line item :

        Can you create sales tax item as product or service?  I couldn't find a way to do it.

        If I just create a tax code item as product then there is 0 tax liability in my tax liability report.

3) Tax override :

        Tax liability getting messed up for tax agency.

My suggestion would be having tax code (group) per line item.  Just like Quick books desktop Canadian version.

That would solve all the issues.

Thanks,
