The New South Wales government is offering increased tax breaks to businesses who hire workers recently made redundant in large scale company restructures.

Employers can now claim a $6,000 payroll tax rebate instead of the $5,000 previously offered.

The only catch is they must hire former employees of companies that have made more than 100 people redundant since the beginning of this year.

Or if the company is in a regional area then employers who have let 50 or more people go.

It means Qantas workers in New South Wales who are facing the prospect of losing their jobs would be eligible.

It will also help former Alcoa employees.

The Aluminium producer recently announced it will close its facilities in Victoria and New South Wales, leaving almost 1,000 people out of work.

New South Wales Premier Barry O'Farrell says it will give employers an incentive to take on new workers.

"This is about trying to do something practical to assist with people being re-employed," he said.

"Boosting the payroll tax rebate from $5,000 to $6,000 for people who face restructure is one way to do that.

"Any job loss is concerning but it is particularly worrying when retrenchments cause significant disruptions to a region or when those jobs are in a specialised field where there are limited opportunities for re-employment."
