Yet another corporate leader has questioned Treasurer Scott Morrison's statement that corporate tax cuts are now a matter of "urgency".

ANZ chief executive Shayne Elliott, who just announced a $6.9 billion profit, questioned the wisdom of rushing through corporate tax cuts.

"I think the question that needs to asked really quickly ... about corporate tax cuts is how are they going to be funded?" he told the ABC's The Business program.

"It's a very different proposition for the Government to say we're going to cut corporate taxes because we're going to shrink our spending, as opposed to we're going to cut corporate taxes and we're going to increase borrowing."

"We need to understand how that's going to be accommodated — I think that's an important part of the equation."

The Treasurer said the tax cuts were now an "an urgent matter" earlier this week, following the release of the Productivity Commission's latest report, which highlighted the need for reforms to increase wages and productivity.

However, Mr Elliott has doubts about how quickly businesses would be able to transfer any additional wealth into higher wages and higher productivity.

"They are linked whether they're linked very quickly, in timing or amount, that is up for debate," he said.

The Senate has already passed $24 billion of the Turnbull Government's $50 billion program of company tax cuts — cutting the tax rate for small and medium size businesses from 30 to 25 per cent, but not for big corporations.

Mr Elliott is not the first business leader to question the wisdom of corporate tax cuts.

Last week, Telstra chairman John Mullen told The Business he didn't see it as a "priority".

"I think governments have more pressing matters on their plate at the moment to address than corporate tax cuts," Mr Mullen said.

"I totally agree, long-term, they are definitely stimulants of the economy and they would be good things.

"But I wouldn't make it my number one priority right now."
