So I had to fill out an ir330c for some contract work I do and I noticed when having to select a tax rate that there is a massive range of tax rates based on what type of contract work you do.
From 10.5% for home help, 15% for being a guard, 20% for modeling to 33% for being an examiner.
I thought one of the advantages of the NZ tax system is that it is relatively simple.
Does anyone know why these different rates exist?
