Does Your Repair Shop Need GST Registration?
If your mobile repair shop's annual turnover exceeds ₹20 lakhs (₹10 lakhs in special category states like Himachal Pradesh, Uttarakhand, etc.), GST registration is mandatory.
Even below this threshold, voluntary GST registration is recommended because: - It lets you issue proper GST invoices to corporate clients - You can claim Input Tax Credit (ITC) on spare parts purchases - It makes your shop look professional and trustworthy

CGST vs SGST vs IGST — When to Apply Which
This is where most repair shop owners get confused:
Within the same state (e.g., you're in Tamil Nadu, customer is from Tamil Nadu): - CGST: 9% (goes to Central Government) - SGST: 9% (goes to State Government) - Total: 18%
Between states (e.g., you're in Maharashtra, customer's billing address is Karnataka): - IGST: 18% (goes to Central Government, then shared) - No CGST or SGST
Practical tip: For walk-in repair shops, almost all transactions are intra-state. You will primarily use CGST + SGST.

Filing Your GST Returns
As a repair shop, you will primarily file:
- GSTR-1: Monthly/quarterly — outward supplies (your invoices) - GSTR-3B: Monthly — summary return with tax payment - GSTR-2B: Auto-populated ITC statement
MobiBix exports all billing data in the format needed for your CA or for direct GSTN filing.

Input Tax Credit — Claim Back GST on Parts
One major benefit of GST registration: you can claim back the GST you pay on spare parts purchases.
Example: - You buy a screen for ₹1,000 + 18% GST = ₹1,180 - You charge the customer ₹1,800 + 18% GST - You owe: 18% of ₹800 profit = ₹144 - You claim: ₹180 paid as input credit - Net GST to pay = ₹0 (plus you save ₹36)
This system rewards proper GST billing and record-keeping.
