Inland Revenue is under fire, for refusing to release a report into the quality of its tax law.
Newstalk ZB has requested the report, which was first commissioned in 2019, but wasn't completed until last month.
But the IRD has rejected the request saying releasing the report would undermine the tax law system.
But PWC tax law expert Geof Nightingale told Mike Hosking there's no reason why it should be withholding the report.
“I suspect it says that the tax laws are too complex and very hard to follow but I just can’t understand why they need to keep that secret.”
