Do small mobile repair shops need GST registration?

Under general GST rules, service-led businesses typically need to register once turnover crosses ₹20 lakh (₹10 lakh in special category states), while predominantly goods-based businesses register at ₹40 lakh in most states — a repair-and-parts shop usually falls under the services threshold. These limits are set by notification and can change, so verify the current threshold on the GST portal before assuming you’re under or over it.
