Even if the seller’s turnover is under Rs. 10 lakh, they will have to take GST registration because they are selling on e-commerce.
Human-Centric Impact of GST Registration
GST registration has increased transparency and compliance in the Indian business ecosystem. But it has also forced people in the unorganized sector to become digitally competent. Small shops or freelancers who earlier worked in a cash-based system now have to understand documentation, invoice, return filing.
This system boosts financial inclusion – like getting a GSTIN has made it easier to get an MSME loan. But rural or non-tech savvy businesses need to learn and support.
