GST has issued notice in portal to those Tax payers who have registered but failed to update their bank details. It is always advisable to update Current account of the registered tax payer. In case Savings account or personal Bank account is updated in case of default of attachment your registered Bank account will be frozen from doing any activity.
We have seen Many GST registered tax payers running business and filing returns ignoring Bank account update note from GST but now Government is Serious and have given 45 days time line to comply or else they will cancel the registration.
