South Australian whistleblower Richard Boyle has accused the Australian Taxation Office (ATO) in court documents of being "callous" after taxpayer threats of suicide went ignored by senior Adelaide staff members.

The South Australian District Court has released Mr Boyle's 50-page affidavit, as the former public servant applies to be declared immune from prosecution.
