Multi-Branch and Multi-Business GST: One Owner, Many GSTINs

One GSTIN per state

GST registration is state-wise. A business operating in three states needs three GSTINs and files returns for each.

Distinct persons

Branches with different GSTINs are 'distinct persons'; supplies between them are taxable and need a tax invoice even without payment.

Cross-charge

Head office expenses benefiting branches (rent, salaries, software) are cross-charged with GST; the branch claims ITC.

Separate books, one login

Keep separate invoice series, clients and reports per GSTIN, but avoid juggling multiple logins.

SmartGST multi-business

Add each GSTIN as a business under your account and switch with one click; every report and invoice series stays isolated.
