He began refereeing in 1987, eventually officiating in the
Southern League until 2002, during which he was promoted to the list of Football League
assistant referees (in 1998). He was a referee in the
Football Conference South from 2002 to 2003. As an assistant referee, Tanner officiated in the
2003 FA Trophy final. In the same year, he progressed to the National List of Football League referees, taking control of his first match on 9 August 2003, between
Football League Third Division sides
Kidderminster and
Mansfield Town, the home side winning 2–1. He took charge of the
Championship play-off semi-final second leg between
Watford and
Crystal Palace at
Vicarage Road on 9 May 2006, which ended 0–0. Tanner was promoted to the
PGMO Ltd Select Group of referees at the start of the
2007–08 season. He had already refereed three Premier League games in the previous season as 'trial' matches, the first of which was the encounter between
Reading and
Everton at the
Madejski Stadium on 23 December 2006, with the away side winning 2–0. However, the second of those appointments, Watford against
Wigan Athletic, was abandoned early in the second half due to heavy rain with the score at 1–1. The match was subsequently struck from Premier League records. On 13 May 2007, Tanner was man-in-the-middle for the
Championship play-off semi-final first leg between
Wolves and
West Bromwich Albion at
Molineux, which finished in a 3–2 away win. On 1 January 2008 he was added to the
FIFA list of referees, allowing him to referee in international and continental competitions. Tanner had his place on the select group of referees relinquished, along with
Keith Stroud, in November 2009, and has therefore also lost his place on the international list for 2010. Following the 2011/12 football season, Tanner took up the role of Referee Development Officer at
Gloucestershire FA, and subsequently retired from refereeing.
