Mr Whyte said the scheme would stop middle and upper income families getting support from the Working for Families scheme but would make up the difference with the lower tax rate.
Cutting the amount of red tape was also imperative to improving the economy and Act would advocate to have the Resource Management Act repealed as part of the move to cut regulation, he said.
"Regulation is completely out of control," he said. "The RMA is just an outright assault on property rights."
Mr Whyte said welfare reform was also needed to get the 200,000 able-bodied New Zealanders currently receiving welfare back into the workforce.
"Being on welfare should not be a potential career." Act proposed lifetime limits on the amount of time a person could receive welfare for, he said.
The final aspect of the party's plan was to improve education through the creation of more charter schools, he said.
