Hello @Mochenpa
Thank you for reaching out to the Community regarding your issue, although I am sorry to hear that you are experiencing issues with your Paypal payments. I was taking a look at the issue you were having and there's a couple of ways we could approach the issue.
The first and quickest way would be to remove the tax from the Quicken invoice. This should then report correctly to your customers but it might not record correctly inside of Quicken.
The second thing we could attempt is to gather information so that the developers could review the issue. If you'd like to do this we'll want to collect a couple of different pieces of information. First, is what version of Quicken are you using? You can find out by going across the top to help > about Quicken. Has the PayPal link always behaved this way? Or is it new behavior? If new, how long has it been happening and did anything change just prior to when it started showing up incorrectly?Next is if we could get a couple of screenshots to better help to illustrate this issue. We'll want screenshots of the invoice in Quicken and also the Paypal Link with the different amounts(You'll want to remove any personal or sensitive information). Any additional screenshots on how to reproduce this that might help would also be appreciated. I'll leave a link down below on how to do so.

Note: you may need to drag the photos into the response box in order to add them to your post.
Please let us know what option you want to try and we'll see about correcting the issue you're having.
Thanks,
