Instead Neilson said it wanted to change the effective tax rates on savings to the same marginal tax rates which savers pay on their other income.
It believes this would be possible by dropping the current KiwiSaver funds tax rates of 28 per cent, 17.5 per cent and 10.5 per cent to 15 per cent, 8 per cent and 4.3 per cent respectively.
The council has produced research showing a KiwiSaver member on the top fund tax rate of 28 per cent and income tax rate of 33 per cent would see a 54.7 per cent impact from tax on their cumulative return on savings over 40 years.
"Over 40 years saving someone in KiwiSaver would face an effective tax rate of 54.7 per cent when their KiwiSaver fund tax rate is 28 per cent and the marginal tax rate they pay on their other income is 33 per cent.
"You might ask, how can the effective tax rate be so much higher than either the KiwiSaver fund tax rate of 28 per cent or the marginal tax rate?" said Neilson.
But Plunket said he believed it was misleading the describe the 54.7 per cent figure as an effective tax rate because it was not an annual basis.
"The FSC seems to be claiming, for example, that a KiwiSaver investor who contributes for 40 years faces an effective tax rate of 54.7 per cent.
"The FSC then uses that 54.7 per cent figure to support its claim that KiwiSaver investment is over-taxed."
Plunket said he understood the Financial Services Council was not proposing to exempt KiwiSaver income from tax until the money was paid out or remove the KiwiSaver subsidies but if its claim that KiwiSaver was being over-taxed was correct then making those changes would be the best approach to solve the problem.
"The simplest way to get that figure down to 28 per cent or less for all KiwiSaver investors is to exempt KiwiSaver income from tax until it is distributed, plus remove the KiwiSaver subsidies."
