Mazars is a global audit, accounting and consulting group employing more than 20,000 professionals in 86 countries through member firms.[1] With head offices in France, Mazars has a network of correspondent partners and joint ventures in a further 21 countries and is a founding member of the Praxity alliance, a network of independent firms.

Worldwide turnover for the integrated partnership for the fiscal year ending August 2014 was 1.081 billion euro.[2] Mazars operates as a single entity as a fully integrated partnership. Mazars publicizes its consolidated financial accounts, a move it claims is unusual for private audit and advisory firms.[3]


The original Mazars firm was formed in Rouen, Normandy in France in 1940, by Robert Mazars. Mazars stayed a local firm until the 1980s when former CEO Patrick de Cambourg started to internationalize the firm growing the business from 33 employees in 1977 to the global firm of today.[4]


Mazars merged with accounting firm Guérard Viala to form Mazars & Guérard in 1995.

United Kingdom[edit]

On 1 September 1998 Mazars & Guerard merged with the British accountancy firm Neville Russell and traded, in the UK, for a number of years as "Mazars Neville Russell". In 2002, "Mazars Neville Russell", as well as its counterpart firms across Europe, changed the name to become simply Mazars. Mazars currently employs 1,600 people in 20 offices[5][6] in the UK and turnover is around €100m.[7]

In April 2007 Mazars merged with the London office of MRI Moores Rowland which will create a firm with turnover in the UK exceeding £90million.[8]

Mazars, prior to the MRI Moores Rowland merger, was listed as the 14th-largest accountancy firm in the UK with about £65 millions fee income,[9] however following the merger and with the merger between Grant Thornton and RSM Robson Rhodes in the summer of 2007, Mazars was listed as 12th[10] with an estimated fee income of £90.3m.

"Neville Russell" was founded in 1900 by Charles Neville Russell to work principally with the insurance sector of the economy. Neville Russell developed a reputation in London of being specialists in this area.

Mazars is a keen advocate of a more open audit market and notably of joint audit.


In 1987 "Rawlison Hunter" joined forces with Mazars.[11] From then Mazars has gone from strength to strength in Ireland joining and merging other firms. Mazars now has three offices in Ireland, in Dublin, Galway and Limerick with 22 Partners and over 400 professionals.[12]


As of 2000 Mazars integrated "Paardekooper & Hoffman" (of the Netherlands), which employed 800 people. In the Dutch audit market Mazars ranks as the sixth-largest firm and contributes more than 15% of the total global turnover.

Jan Paardekooper founded "Paardekooper & Hoffman" in 1927. The firm worked with large clients involved in the maritime and harbour businesses of Rotterdam.
