With recent (last 12 months) changes to the tax and centrelink laws pay pal must supply all information to them if the pay pal account grows by $20,000 or more in any financial year.
Using pay pal a lot outside of
ebay sounds like a no no as well.
The scammers are the only ones that have been demanding pay pal information from me.
I make sure all my pay pal records go to the tax man and centrelink every year no matter what the income might be.
