According to data compiled by Tussell, the firm was paid £401m in government contracts in the 12 months to November.
Among the other Big Four firms, PwC received £182m, EY was paid £40m and Deloitte earned just £48m.
In total, between November 2015 and November 2016, the firms were paid £673m by the different government departments.
The data also showed that the number of work awarded to Deloitte has been declining since June.
In November, the Times leaked a document produced by Deloitte which claimed the government had no “overall negotiation strategy” for Brexit. Theresa May’s office then accused the firm of “touting for business” through the “unsolicited” analysis.
The firm later apologised over the leaked memo and said the note was for internal audiences only. As a result, Deloitte is believed to have agreed not to apply for any lucrative central government contracts for the next six months, according to reports.
The departments that spent the most money with KPMG on contracts were the Cabinet Office, the Ministry of Defence and the Police and Crime Commission.
In October last year, an FOI request from former Public Accounts Committee chair Margaret Hodge found that the biggest spenders within government were the Department for International Development (DFID) and the Ministry of Defence.
The accounts showed that PwC, KPMG, Deloitte and EY were paid £98.5m by the DFID in the 2015/16 financial year. It spent £4.1m on Deloitte, £37.9m on KPMG, £302,743 on EY and £56.1m on PwC.
