The National party is to unveil its taxation policy on Monday.
National leader Bill English is expected to promise small cuts in taxation as part of his party's wider economic package.
National MPs have indicated the party will look to cut the corporate tax rate to 30 cents from the current 33
cents in the dollar.
A reduction in the current top tax rate of 39 cents for individuals earning over $60,000 has also been mooted.
One other option mooted was lifting the threshold people have to earn before they move to higher tax rates.
National MPs have been fiercely debating the tax issue. Many wish to go into the election promising lower rates. However, Mr English has been reluctant to commit to drastic changes.
Mr English fears that the Government will be able to paint National as a party that would have to cut social spending in order to pay for its tax promises.
He had been seeking to wait until the Government's upcoming budget revealed how much money an incoming government may have to spend before finalising policy.
His colleagues have argued that National's plans to scrap Finance Minister Michael Cullen's superannuation fund will give the party room to implement tax cuts and increase spending in other areas.
National's finance spokesman David Carter said today "the impact of taking the super fund out of the fiscal equation and putting in National's proposed tax cuts means we will run lower operating balances, but will also have significantly lower debt".
Claims the tax cuts would lead to lower social spending "are simply not true," Mr Carter said.
