I have had received a letter from ATO twice this year, both letters are exactly the same except "Our Reference". The letters mentioned I have CGT needs to report due to shares sold (which I don't own shares account) . I have called ATO through interpreter line. ATO said the "our reference" should be numbers not letters. The reference in my letter is "IAI-CGTS-PD". So, ATO started to ask my passport number, centerlink number, driver licence number, it feel like a scam.
So, is this letter a true letter from ATO???
