There is currently $681,000 in unclaimed money in the Orange local government area.

There is also $699,000 in the Dubbo council area and $546,000 at Bathurst.

Finance Minister for Damien Tudehope said more than $442 million in forgotten money was sitting with Revenue NSW across the state.

He said that money includes share dividends, trust accounts, refunds, commissions, deceased estates and money from a range of other sources.

"We know many people are doing it tough, especially during the COVID-19 pandemic, and households are having to keep a close eye on their budget, which is why I encourage people to check their eligibility," Mr Tudehope said.

"You could have hundreds or thousands of dollars that you didn't know about.

"This money belongs to the people of NSW and I want to make sure it goes back to its rightful owners."

Revenue NSW holds more than a million unclaimed items from private companies, State Trustees, local councils and government agencies that cannot be returned because contact details are out of date and they cannot be tracked down.

"It's quick and easy to check if you have unclaimed money," Mr Tudehope said.

"Simply visit the Revenue NSW website and type your name into the free search tool.

"If you do have a claim, notify Revenue NSW and collect your money.

"It only takes a few minutes and you could walk away with some extra money in your pocket."

The NSW Government holds unclaimed money indefinitely until it is claimed.
