Need for tax audit

I have been doing share  trading, both  intraday and delivery since 2004 and have got my accounts tax audited till last year. Since I have incurred business losses  due to trading, I have carried forward losses of about Rs.3lacs. I have curtailed my share trading severely and my turnover during F/Y 2009-10 may be only around Rs30 lacs ,both intraday and delivery. Is it necessary to get my accounts tax audited for F/Y 2009-10 ? Is there any compulsion to undergo tax audit if one has to get the benefit of tax credits against carried forward  loss at a future date eventhough the current turnover may not entail tax audit?

Thanks
