I make my amount taxable but when I send invoice it sends it without tax wondering why?

Hi shane55-hotmail-,

Thanks for taking the time to reach out to us in the Community. I can see the importance of being able to send your invoices with tax and I'll be happy to help. QuickBooks Self-Employed is geared for business owners that are on the go with their work.

Based on what you've described, I recommend checking to make sure your taxes are set up. This article here does a great job at explaining how the tax module works in QB Self-Employed. I encourage you to check that out and let me know how you make out. Make sure that your changes are saved as that could be the reason why the invoice is sending without taxes. 

Let me know if this info here helps. In case you need further assistance, don't hesitate to reach back to me in the comments below, I've got your back.
