"We propose more stability in funding for third sector success, particularly for small, local organisations," the Chancellor said.
Brown pledged a £30m fund to transfer community assets to voluntary groups.
"Ownership of assets can provide communities with a financial and social stake in their areas," he said.
And the Chancellor announced plans for legislation to create an unclaimed assets scheme. Money from dormant bank and building society accounts will be reinvested in local projects.
The pre-Budget report says: "To enable the banking industry to set up an unclaimed assets scheme, where both consumer and industry are protected, it is necessary to bring forward enabling legislation."
The Government will consult on how it can encourage young people to volunteer for the 2012 Olympics. Brown said 100,000 volunteers had already been secured.
And the Chancellor endorsed the public services action plan and the initial findings of the Treasury's third sector review.
The interim report on the review named five areas in which the Government would consider how charities can assist social and economic regeneration. It will look at campaigning, communities, public services, social enterprise and a healthy third sector.
