Finance Minister Mathias Cormann wants to help families get ahead, businesses to become more successful, while ensuring energy is reliable and as affordable as possible.

But a ReachTEL poll reported in Fairfax Media of the electorates of Prime Minister Malcolm Turnbull and his predecessor Tony Abbott found many voters do not believe the government is going the right way about it with its planned business tax cuts, and want more money spent on renewable energy. .

More than half of voters in Wentworth and Warringah think the present 30 per cent business tax rate is about right or too low, while six in 10 favour policies closer to Labor's 50 per cent renewable energy target.

The government has indicated it will use the autumn session of parliament to push ahead with its 10-year business tax plan to cut the rate from 30 per cent to 25 per cent.

The first leg would lower the rate to 27.5 per cent for businesses with a turnover of up to $10 million.

"We are focused as a government on families getting ahead and businesses being the most successful they can be and hire more Australians," Senator Cormann told ABC radio on Tuesday.

"We make no apologies for that."
