Charities have only a few days left to submit retrospective VAT-refund claims for tax paid on fundraising costs.
In July, the Children's Society won a landmark court case over the recovery of VAT on fundraising for unrestricted funds.
HM Revenue & Customs has said it will not appeal against the High Court decision, but it has not yet confirmed the exact date by which charities will have to submit claims for VAT they were unable to recover before 30 September 2002.
However, it is thought that the deadline is likely to fall at the end of September. There have been suggestions that the claims could be worth £50,000 a month to some charities.
Any claims for tax lost between October 2002 and August 2005 can be submitted at the end of the year.
Charities will not be able to submit their claims until HMRC releases a business brief. The appearance of the brief was imminent as Third Sector went to press.
