Question 1

How do I find the HSN code for my product?

Accepted Answer

Type the name you use in the shop, in English or Hindi (atta, chawal, chappal), and the matching index cards show the HSN code, what it covers and the GST rate. Click a card to copy the code into your billing software.

Question 2

How many digits of HSN code do I need on my invoice?

Accepted Answer

If your turnover in the last financial year was up to ₹5 crore, show at least 4 digits on invoices to registered buyers (B2B). Above ₹5 crore, show 6 digits on every invoice. Services always use the 6-digit SAC.

Question 3

What is the difference between HSN and SAC?

Accepted Answer

HSN (Harmonised System of Nomenclature) codes classify goods; SAC (Services Accounting Code) codes classify services and start with 99. A shop that sells goods and also repairs them uses both.

Question 4

Why is atta 5% GST in one place and 0% in another?

Accepted Answer

Staples like atta, rice and dal are nil-rated when sold loose, and 5% when pre-packaged and labelled for retail sale. The cards show both rates where it matters, along with other conditions such as the ₹2,500 limit for clothes and shoes.

Question 5

What are the GST rates from 22 September 2025?

Accepted Answer

Most goods now fall in two slabs: 5% for everyday items and 18% for the rest. A 40% rate applies to a short list such as sugary and caffeinated drinks, and essentials like fresh produce, milk and notebooks are nil. Gold and silver stay at 3%, and rough diamonds at 0.25%.
