Sony has projected a net loss of 520 billion yen ($A6.3 billion) for the fiscal year ended March 31, more than double the initial estimate of 220 billion yen ($A2.6 billion).
The company last financial year posted a net loss of 259.6 billion yen ($A3.1 billion).
In a statement to investors today, Sony blamed an additional United States tax expense of 300 billion yen in the fourth quarter of last year for the revised forecast.
Reports emerged yesterday that the company would shed 10,000 employees from its global workforce as part of a company-wide restructure.
It is the second wave of major job cuts in three years. In December 2008, Sony revealed plans to shed 16,000 jobs to cut costs during the global financial crisis.
Regardless, Sony predicts it will return to positive operating results by the end of the next fiscal year, with consolidated income forecast to hit 180 billion yen.
Sony's projected revenues for 2012 are unchanged at 6.4 trillion yen, down from the 7.18 trillion yen in revenue posted last fiscal year.
Sony's shares were down 3 percent from 1629 yen ($A19.7) to 1586 yen ($A19.1) in the opening minutes of trade on the Tokyo Stock Exchange today. Sony is also listed on the New York Stock Exchange which opens early this evening AEST.
