Reforming Gift Aid is at the top of the Conservative Party's agenda on the voluntary sector, according to shadow charities minister Nick Hurd
He told an Institute of Fundraising conference in London that the Conservatives were more likely to develop a composite rate of Gift Aid than pursue an opt-out system, which he said would be more difficult.
He said if the Conservatives won the general election they would attempt to reduce the "bureaucratic burden" of Gift Aid on charities.
He said Angela Smith, the third sector minister, had told him the reason the Government had not yet reformed Gift Aid was that "the sector has not got its act together about what it wants".
Hurd said that a Conservative government would give charities more opportunities to deliver public services, but contracts to run these services would be longer term and based on outcomes. He said the contracts would allow charities to earn a return on the investment, rather than just full cost recovery.
"David Cameron is a man with a social mission, and the third sector is a huge part of that," he said.
He said there had been some concern in his party about the weight attached to campaigning by some charities. "There is a risk of excessive politicisation of the sector, but we are happy with the status quo on the regulations about campaigning," he said.
