Victim Support, Life Education Centres and the Woodland Trust are among the nominees for the Charities Accounts Awards.
The awards, sponsored by CAF and the Institute of Chartered Accountants of England and Wales, are more than 20 years old, but for the first time will judge accounts that are available online.
In the top income category the battle for the top prize of £2,000 is between Historic Royal Palaces, Victim Support, the North Humberside Hospice Project, the Royal Air Force Benevolent Fund and the Woodland Trust.
Chair of the judging panel Graham Ward said: "The judges found some excellent examples of online reports and accounts in every size and type of charity.
The shortlisted entries have demonstrated innovative use of new technology to help donors understand how their money is being spent."
The winners in all four categories will be announced at a ceremony at the Chartered Accountants Hall on 28 November. As well as the cash prize, winners will get a seal to display on their website.
