Income tax notice u/s 133 (6) . followed by notice u/s 148

No need to mention about permission in the notice u/s. 133(6)......

Unless properly replied, permission for scrutiny can also be obtained.

But as per Section 133 (6), if no assessment procedings are ongoing AO needs to take permission from Comissioner before issuing notice U/s 133 (6)

Yes, agreed........... in case of inquiry when no proceeding are pending against assessee. (circular no 177 dated 18th August 1995), But it may not be disclosed in the Notice!!

Yup. Thanks for the response.

Still m not able to clarify that not mentioning the fact in the notice that "Prior permission has been obtained" will invalidate the notice..acc. to me
