An 80-year-old accountant who owes Inland Revenue around $500 million wants the High Court to approve his proposal to pay $1000 a week off the debt.
If John George Russell's bid fails, it places him one step closer to bankruptcy, which the tax department appears intent on pursuing.
Russell, a former merchant banker who lives in Kawakawa Bay, is best known as the governing mind behind a template that the Court of Appeal called a "blatant tax-avoidance scheme".
According to that same court, the accountant established an "elaborate, maze-like structure of companies, partnerships and trusts" and provided advice on how others could avoid tax through their participation in the Russell template.
Only 1 per cent of the $500 million bill is core tax, the rest being penalties and compound interest.
