A New South Wales Coalition government will cut pokie taxes by $300 million over four years if clubs agree to contribute more to community organisations.

In 2004 the State Government increased tax rates on gambling revenue for large clubs but the Opposition has announced a plan to wind rates back.

Opposition Leader Barry O'Farrell says the plan will create 2,000 jobs and raise community contributions from clubs by $270 million a year.

He says the policy will ensure clubs remain viable but also contribute to the community.

"When clubs are unable to provide funding to local social, community and sporting groups what happens is those groups come to Government," he said.

"It makes a lot of sense to ensure that clubs are able to do the job they've done for more than 50 years, which is support local neighbourhoods, support local groups through funds they're raising in their clubs."

Mr O'Farrell denies the announcement has anything to do with donations from clubs to the Liberal and National parties.
