As per section 24 of the Central GST Act, every person who is earning any income from outside the state or outside the country is required to get GST registration and the exemption limit shall not apply.
In other words, the exemption limit of Rs.20 lakh is only valid for small dealers/service providers who generate their income from within state, but if you are a service provider i.e. blogger, and generating income from outside India (export of services), then GST registration is mandatory and exemption limit shall not apply.
