Tuesday's budget will include a migration overhaul, tax relief for small businesses and fresh efforts to cut red tape, in a push Treasurer Jim Chalmers says will save businesses money and boost Australian living standards.Further uses for the digital identification system myID and a government-backed crypto token will also be considered in a wide-ranging productivity package Mr Chalmers said was "one of the most important parts" of his fifth budget."We won't get the higher living standards we want and the wages we want unless we turn this productivity performance around," he told the ABC in a pre-budget interview.Productivity, a measure of our economic capacity which economists say must grow if Australia is to become richer over time, has hit a 60-year low in the last decade."If we're going to shift this decade-long problem, we've got to think about it in new ways, and we've got to work out how we can act on a really broad range of fronts," he said.The headline promise is to slash the cost for businesses of complying with government regulations by $10 billion a year The government has set itself a big task over the next year to get this done."Ms Wood said she was disappointed that the government had decided against pursuing changes to company tax, saying it was clear that the current system constrained investment and that this was holding back productivity growth."Making inroads on that does require some kind of budget hit, and it's understandable that the government is grappling with that in the current environment
