With that, the government's three-day summit on economic reform is a wrap!

And so that's the end of our live blog for today too. Thank you for joining us.

We'll be back again tomorrow morning to bring you all the day's developments in federal politics.

One last point I didn't get to before the treasurer wrapped was a hint on more to come with tax reform.

The treasurer said he left it till last because it was the last item on the roundtable's three-day agenda (it's also one of the trickiest).

Chalmers says after hours of debate there was "a lot of support" for trying to put a "structure" around the work he and the government would now undertake.

He laid out three objectives the government would try to address in the tax system:

1. Ensuring a "fair go for working people ... including intergenerational equity terms".

2. Finding an affordable, "responsible" way to incentivise business investment, recognising a capital deepening challenge in the economy.

3. Making the system "simpler" and more sustainable so that the services people need can be funded, particularly in relation to ageing and other budget pressures.

We heard the treasurer say in June no sensible progress could be made without tax reform. Now he has spelled out where he may be looking.

Treasurer Jim Chalmers says if there was one defining element of the contributions from people at the table, it was that it was "intergenerational".

"We recognise that we as people of influence with this opportunity have responsibilities in lots of ways, but especially inter-generational responsibilities and we take them very seriously," Chalmers says.

"And I drew great strength and confidence from their contributions."

He wraps by saying the last three days were about confronting Australia's challenges, and finding the opportunities in them.

"And we believe that we give ourselves a much better chance of being the best in the world at confronting those challenges in an upfront way, in an honest way, and in a decisive way if we include more people in that task. That's what the last three days was all about."

Treasurer Jim Chalmers has not ruled out that some tax changes progressed at the productivity roundtable could be introduced before the next federal election.

Chalmers cited the road user charge, which the government argues it had raised before the last election.

He says it is ultimately a matter for cabinet, but a blanket rule on timing could not be applied because in his view work had been underway on a number of issues already.

The treasurer says there was no settlement among the group on whether Australia should create a dedicated AI Act, as desired by the unions, or a less invasive plan to close gaps in Australia's laws.

But Chalmers says the group got "a bit closer" to agreement, including a process to settle copyright concerns raised by artists and content creators over the use of their work by AI tools.

He says a gap analysis will identify what legislative response will be needed to the rapid rise in use of AI.

The treasurer says among some of the projects government will pursue are also recognising international standards so skilled workers don't have to get re-qualified in Australia, opening up opportunities for prefabricated and modular construction and looking at the performance test for super funds, which some argue disincentivise housing investment.

Chalmers says there will be a "heap" of work for treasurers to dig through at their next meeting in September.

So it sounds like a road user charge is all but committed to now, with the treasurer saying he will meet with state counterparts on September 5 to nut out the next stage of developing a charge.

Chalmers hasn't specified who it would cover (yet), but there is broad agreement one is needed, as the uptake of more efficient cars and electric vehicles whittles away at revenue from the fuel excise.

It will be a major reform and need the assistance of the states to develop.

Chalmers says there's no final model yet, but committed to working with NSW Treasurer Daniel Mookhey and with his cabinet colleagues on an options paper.

NSW has already legislated a road user charge, which is due to begin in 2027 unless a federal scheme replaces it.

The Treasurer Jim Chalmers has laid out a number of measures the government will pursue after finding broad agreement at the productivity roundtable.

The quick wins the government will move on are:

Scrapping more "nuisance" tariffs, which the treasurer will do in conjunction with Trade Minister Don Farrell.

Reducing housing red tape, which Housing Minister Clare O'Neil will investigate.

Accelerating EPBC reforms, which Environment Minister Murray Watt has said he would like to see legislated by mid-next year.

Clear a backlog of environmental approvals on housing and other projects, to be worked through by Senator Watt, Ms O'Neil and Finance Minister Katy Gallagher.

Reforms to remove regulatory double ups, which Senator Gallagher will work on, with a commitment to introduce a regulatory reform bill to progress that.

Industry Minister Tim Ayres will accelerate work on a national AI plan.

And the treasurer said while more work would be needed, there was broad agreement to introduce a road user charge, which would set a price on how far cars drive.

The treasurer says over 29 hours of discussion there was about 327 different contributions made by attendees to the economic reform roundtable.

Among them were a number of areas of consensus, Chalmers says.

He says there were ten "pretty clear" areas of agreement that set some reform directions for the government, and another several ideas that could be moved on quickly.

The ten reform directions were:

Progress towards a single national market

Simplifying trade and reforming tariffs

Better regulations and cutting clutter

Speeding up approvals in national priority areas

Building more homes more quickly

Making artificial intelligence a national priority

Attracting capital and deploying investment

Building a skilled and adaptable workforce

A better tax system

Modernising government services

Treasurer Jim Chalmers has concluded the government's three-day economic summit saying he is grateful for the spirit of businesspeople, academics, union members and politicians at this week's event

"The best way to sustain and grow living standards over time is to make it more productive, to make it more resilient and also to make sure that our budget is more sustainable," he says.

"These were the tasks that we set some terrific people to ... over the course of the last few days."

He says now the hard work really begins.
