Can someone tell me why I cannot add hst on the create bill screen? This is a new problem in the last week or so. Has something changed?

Welcome to the QuickBooks Community, @shelley-willaway! It's great to have you here, and I'm delighted to assist you with your first inquiry about adding HST (Harmonized Sales Tax) when creating a bill in QuickBooks. I have some suggestions that should help, and I'm eager to walk you through them.

If you don't see the HST as an option when adding a sales tax to a bill, please ensure this tax rate is active in your QuickBooks Online (QBO) account, since inactive ones can't be added.

Here's how:

1. Click the + New button and choose Bill.   
2. Fill in the required details and proceed to add Sales Tax.   
3. Hit the drop-down arrow and tap the Manage rates option.   
4. Toggle the HST switch on, then press the Done button.     

If the issue persists after checking your HST settings, it's worth addressing potential browser-related problems by clearing your cache and cookies. Accumulated data can sometimes interfere with the software's efficiency. I'd also suggest using a supported, up-to-date browser to have the best experience with QBO.

Finally, check out this article when it's time to manage a payment towards a bill, depending on the pay method you use: Enter and manage bills and bill payments in QBO.

These steps should resolve the issue and allow you to add HST to your bills again, @shelley-willaway. If you're still having trouble after trying these suggestions, please let us know. The Community forum is always here to help you out!
