How many days it takes to itr processed?

1. For Individuals/HUF ...On an average 2 months for ITR 1&2 and 4 to 6 months for ITR 3&4.

2. ITR gets proceesed befot issue of any refund order.

3. Usually a week.....

Is there is a slight difference in IT Refund period whether "self filed" or thro Auditor Filed under his Practioner sign in ?

Past 3 years I self filed ITR 1 and got the refund with in 3-4 weeks .( but no deductions of any sort claimed . Just 26AS  income with TDS deducted shown)

My wife files ITR1 thro her long term Auditor (from her Dad's days) and gets refund in 2 to 21/2 months
