There are different videos explaining the process for charities in three different income brackets between £10,000 and £500,000, each of which has different reporting requirements.
Those with incomes under £10,000 have to update their details annually, but do not have to submit accounts. Those with incomes above £500,000 are felt by the commission to be less in need of help.
"The target audience is smaller charities because, looking at the figures, it is the smaller charities that are less likely to have done it online before," said a commission spokeswoman.
The commission is moving this year to a system under which all charities required to file an annual return must do so online. In a statement, it said 86 per cent of charities filed online last year.
"From 2011 onwards, all charities are being asked to submit the required information online, through the Charity Commission’s website," the statement said.
