I wouldn't worry about it too much... it's much more likely that they are backed up at the moment like they say they are, rather than cooking up some elaborate plot to defraud the instructors they depend upon. If withheld taxes were being systematically inflated in this manner I'm pretty sure people would be screaming about it on this forum, and they're not.
I just don't see them doing anything underhanded like that. I wouldn't panic unless you actually see your tax withholding increase. Given that you submitted the documents when required you should be OK.
Hi @Voider2049 I'm sorry for the delay in getting an update from the team as Frank mentioned, there was a backlog with the requests, but I'm able to see your tax form has been received and approved by our tax partners. In case you will like to have specific information about your revenue share or withholding rate, please reach out to firstname.lastname@example.org or follow up under the email you have received.
