The institute's request for financial support came in its response to the Treasury's third sector review.
"We need more resources to drive through the progress we've made," said Alan Gosschalk, chair of the ImpACT coalition. "It's all been done so far on volunteer time."
Gosschalk said the coalition needed funds to recruit more charities, increase its online resources and provide support to members. He said it was too early to tell if the coalition would appoint permanent staff, but admitted it was a possible solution.
Gosschalk added that there were several trusts the coalition might also approach for financial assistance. However, it has not so far identified a target sum.
The coalition was set up last year by the institute, Shelter's Alan Gosschalk, the NSPCC's John Grounds and the NCVO's Campbell Robb, who has recently been appointed director general of the Office of the Third Sector in the Cabinet Office.
The institute has also asked the Government to ensure that fundraising plays a key role in the work of the new centre for research into charitable giving, which is being funded by the Cabinet Office, the Scottish Executive, the Carnegie UK Trust and the Economic and Social Research Foundation (Third Sector, 18 October).
"We want to make sure the centre properly identifies fundraising research and that fundraising gets an equal slice of the cake," said Lindsay Boswell, chief executive of the institute.
The initial results of the review are expected in the Chancellor's pre-Budget report at the end of the year.
