A jury has found Rural & General Insurance founder Charles Pratten guilty of seven charges of obtaining a financial advantage by deception.

Pratten understated his taxable income by about $5 million in tax returns between 2003 and 2009.

He was previously convicted in June 2012 but appealed and a retrial was ordered.

The nine-week hearing took place in front of Justice Stephen Rothman at the NSW Supreme Court.

Pratten remains on bail before sentencing submissions on October 27.
