All charities that spend more than £100,000 a year on fundraising have been asked to pay the levy, but the regulator’s chief executive, Stephen Dunmore, said last week that of almost 2,000 charities that had been asked to pay, about 370 had either ignored requests or refused to pay.
Sir Stuart Etherington, chief executive of the National Council for Voluntary Organisations has called for charities that do not pay to be named, and last week the regulator said it was considering doing so.
The register, published yesterday, includes the names of all eligible charities that have paid the levy, as well as those charities that are not eligible to pay the levy but have paid an annual fee of £50 to register with the regulator.
But it does not reveal the names of the charities that had not yet paid the levy.
Charities that have paid the levy are also automatically registered with the regulator.
One major fundraising charity that has not paid the levy is the International Planned Parenthood Federation, which spent £3.6m on fundraising in the year to 31 December 2015 and had an income of £76m, its accounts show.
Stephen Dunmore, chief executive of the Fundraising Regulator, said: "We are grateful to all charities that have played a role in supporting us by assisting with our set-up costs and by paying the levy.
"This is a commitment to ethical, regulated fundraising in the charity sector and good progress is being made. However, I would urge those that have not paid the levy to do so as soon as possible and for others to register."
