Prof Alexis Jay became the fourth head of the Independent Inquiry into Child Sexual Abuse (IICSA) last month after New Zealand high court judge Dame Lowell Goddard (pictured below) resigned.
The inquiry said: "Professor Jay specifically requested this salary and furthermore did not require the use of a car and driver as provided to the previous Chair."
While her successor has requested a salary of £185,000 per year, Dame Goddard was paid £355,000 in the last financial year.
In addition to releasing details of Prof Jay's remuneration arrangements, the Inquiry also disclosed its financial report for 2015/16 which revealed more than £500,000 was earmarked for Dame Lowell.
Her terms also included a rental and utilities allowance of £119,000, and travel costs worth £67,319 which the Inquiry said "included travel to and from New Zealand for her and her family."
The probe includes in its scope the Church of England, the Church in Wales, the Roman Catholic Church, the BBC, Lambeth Council and residential institutions arranged or provided by Rochdale Borough Council.
After announcing her resignation, Dame Lowell called for a "complete review" of the IICSA, claiming there was an "inherent problem" in its "sheer scale and size".
Prof Jay defended the inquiry earlier this month, which has been described as the most ambitious public inquiry ever in England and Wales, insisting it will not be scaled back.
The IICSA was originally intended to last five years, however, there are suggestions it could take up to a decade to complete.
