That’s right! We say “pay more/less tax” and “have you declared the tax?”, for instance. Although, I am not speaking from a standardized or school grammar perspective. This is just how I - as a native speaker - would use our equivalent of the word “tax”. This brings me back HARD. To times when I used to join various panel discussions to fiercly defend the/my stance on “correct language” - my vague stance being that the ruling classes need to let the actual spoken word and its usage to be reflected back into the academic discourse. End of off topic discussion.
