Hi, iam pediatrician and have a clinic where along with consultation  I sell medicines (5%GST) worth 5 Lakh /year 
Turnover from clinic is 15 Lakh, I also visit other hospitals as consultant where I get additional consultation fee of around 9 Lakh/year so  taxable sale is 5 Lakh  clinic turnover is 15 Lakh but total income is 24 Lakh 
SHOULD I REGISTER FOR GST? Many of the doctors are in similar situation
kindly answer
