Hi I’m trying to add GST/HST on to a invoice but I can’t can you please help

Hi nareeman_hussein,

Welcome to Community!  It's essential that you're able to enjoy the advantages of the sales tax feature in QuickBooks Online.  Ensuring that sales tax is applied to your invoices can be done seamlessly.  I'd be happy to assist!

Once you've set up the sales tax, QuickBooks automatically does the calculations for you on invoices and receipts, so you can submit your filings accurately.  You'll need to turn on the Sales Tax feature to get started.  Here's how:

1. From the left menu, select Taxes and then Set up sales tax

2. Click on Add tax

3. Choose Add under What type of tax do you want to add

4. Follow the on screen prompts and click Add to complete the process

You'll now see the Sales Tax column on your forms!

Here's a helpful article for setting up a new sales tax code, for your reference.  You'll also have the ability to add tax categories to your products and services.

If you have any other questions, please don't hesitate to reach back out.  We'd be glad to help!
