A plain-language guide to GST registration
What a GSTIN actually lets you do
Once registered, you receive a 15-digit GST Identification Number. It allows you to charge GST on your invoices, claim credit for the GST you pay on business purchases, and sell to customers who insist on a registered supplier. It also brings a duty: filing returns on time, even in months with no sales.
Regular scheme or composition scheme
Most businesses register under the regular scheme. Smaller traders, manufacturers and restaurants may opt for the composition scheme, which means a fixed low tax rate and simpler returns, but no input tax credit and no inter-state sales of goods. Picking the wrong one is a common and costly early mistake, so we talk it through before filing.
Choosing the right HSN and SAC codes
Every product or service you sell is identified by a code. The codes you list at registration should match what you really invoice. We go through your actual product list or service description and choose codes that will not cause trouble later.
Address and premises proof
The address you register is where the officer may visit. Rented, shared and home offices are all fine, provided the paperwork lines up — an electricity bill in the owner's name, a rent agreement or a consent letter. Most queries we see come from mismatched address documents.
What comes after the certificate
Display your GSTIN at your place of business, update your invoice format, and note your return due dates. Depending on your turnover you will file monthly or quarterly. Missing the first return is the most common reason new registrations attract late fees.
