44ada and business code 14009

Hi,

I teach at a few educational institutes as a consultant. I do not own those institutes. I am also registered as a GST consultant. So far I have been showing my business code as 14009. But that disallows me to get beenfit under 44ada. Is 14009 the right code for me?

Should I be using some other code and get benefit under 44ada?

Please let me know.

Regards,

Ramesh
