Splitting my expenses to detail HST / GST portion of the expense

Hello ayesha-mirza-ncr,

Thanks for reaching out to us here. Making sure you're recording your transactions properly is an essential step for maintaining clean books. QuickBooks is a powerful program that enables you to enter your transactions without any hassle. 

Based on what you've described, I recommend reaching out to an accounting professional for expert advice on this. If you're not in contact with a professional, don't worry, you can search for one using this link here. In the meantime, I recommend taking advantage of the custom tax feature offered in QuickBooks. The program allows you to set up custom tax rate such as the one you've described. Here's a helpful article with more info about: Creating a custom tax rate. Once you've added the rate, you can use it on your invoices as you would with a regular tax rate. 

Give this a try and feel free to ask other questions, I've got your back.
