Normally when you've got a meta-achievement, you need to complete all of the levels of the sub-achievements.

I did not have all the levels of Good Taxpayer but I got Taxpayer. (This has been fixed on my account by a UA.)

Do you know if there's still an issue with this?

There'd be no way for me to tell sorry, you can only get the Achievement once. They did say that they fixed it.

Locking this then. :)
