Taxes & GST
Settings → Taxes & GST → GST & invoices is one page with three tabs:
| Tab | What it holds | Used to be |
|---|---|---|
| GST numbers | Your business and PAN, a GST number for each state you sell from, and which one is the default. | Settings → Business and GST |
| Tax rules | Your registered legal name and address, whether prices include GST, the default rate and HSN code, the composition scheme. | Settings → Taxes & GST |
| Invoice numbers | How your tax invoices are numbered, and e-invoicing. | Settings → Taxes & GST |
Old links to either page still work and open the right tab. The tab you are on is part of the
address (?tab=tax-rules), so you can bookmark it or send it to your CA.
What this is for
- Keeping every GST number your business holds in one place, and choosing the default one.
- Putting your GST number, legal name and registered address on your invoices.
- Deciding how much GST each order carries when a product has no rate of its own.
- Numbering your tax invoices the way GST expects: every number used once, in order.
If your business is not registered for GST, you can skip this page. Nothing on it is needed.
How GST works here
The Tax rules tab ends with a short guide. The same points, in brief:
- Inside your state: CGST + SGST. When the delivery address is in the same state as your GST registration, the tax is split in half: CGST to the central government, SGST to your state.
- Outside your state: IGST. When it is another state, it is one tax, IGST, at the full rate. The delivery address decides which one; you do not pick it.
- Prices including or excluding GST. Including means the price already has the tax inside it and the customer pays exactly that. Excluding means tax is added on top.
A ₹1,000 item at 18%:
| Price includes GST | Price excludes GST | |
|---|---|---|
| Item value | ₹847.46 | ₹1,000 |
| GST | ₹152.54 | ₹180 |
| Customer pays | ₹1,000 | ₹1,180 |
| Same state | CGST ₹76.27 + SGST ₹76.27 | CGST ₹90 + SGST ₹90 |
| Other state | IGST ₹152.54 | IGST ₹180 |
The example on the Tax rules tab uses your own default rate.
GST per state
Each order is billed from the GST number of the warehouse its products sell from (you choose it per location on Locations). If that warehouse has no GST number chosen, the order is billed from your default GST number.
Your prices already include GST, so this never changes what the shopper pays. It only changes how the tax is split on the invoice:
| Warehouse in | Shopper in | Tax on the order |
|---|---|---|
| Haryana | Haryana | CGST + SGST |
| Haryana | Karnataka | IGST |
| Karnataka | Karnataka | CGST + SGST |
The order page shows which GST number it was billed from, for example Billed from: Haryana · 06AAPFU0939F1ZV. Each GST number also numbers its own invoices and files its own GSTR-1 (see GST invoices).
GST numbers tab
In India you get one GST number for each state where you have a shop or warehouse. If you send orders from Haryana and from Delhi, you have two GST numbers, and both belong to the same PAN.
- Your business shows your legal name and PAN. You do not type the PAN for your first GST number: we read it from the GST number itself (characters 3 to 12 of a GST number are the PAN).
- GST numbers lists each number with its state. We read the state from the first two digits, so you never pick it. The default one has a Default badge.
- Add GST number asks for the 15-character number from your GST certificate. As you type,
the page shows “Registered in Haryana” (or your state). The other fields are optional: an
invoice prefix such as
HR(printed where your numbering uses{GST}), and the address on the certificate, which invoices from this GST number print as your address. - If the number belongs to a different PAN, you see: “This GST number belongs to a different PAN. Is it another business?” Check for a typo first. If it really is another business, use Add it as another business.
- Make default (from the ⋮ menu) switches your default GST number. Mark as cancelled is only for a number the GST department has cancelled; old invoices keep showing it.
More than one business
Open Advanced: more than one business only if a warehouse belongs to a different legal business (a different PAN), for example a partner’s stock you sell.
Selling stock owned by another business makes you an e-commerce operator. Talk to your CA first.
GST numbers and the Tax rules tab
Once you have a GST number on the GST numbers tab, the Tax rules tab shows it read-only with a Manage GST numbers button that brings you back to the first tab. If you have no GST number yet, typing one on Tax rules adds it as your first.
Only owners and administrators can change this tab. Staff cannot open it.
Tax rules tab
GST registration
Type your 15-character GSTIN, like 06AAACW1234A1Z5. The page checks it as you save: a
typo in any character is caught by the check digit at the end. Once the first two digits are
in, it shows the state you are registered in, for example “Registered in Haryana”.
Add your Registered legal name (the name on your GST certificate, which can differ from your shop name) and your Registered address. Both are printed on invoices.
How you charge GST
-
I am on the composition scheme: turn this on only if you chose the composition scheme when you registered. No GST is added to your orders, and your invoices become a “Bill of Supply” with the words “Composition taxable person, not eligible to collect tax on supplies”.
-
My prices include GST: on by default, the usual way in India. The price you type is what the customer pays and GST is worked out from inside it.
Adding GST on top of your prices at checkout is not built yet. You can switch this off to record how you price, but for now customers still pay the price you type.
-
Default GST rate: used for any product that has no rate of its own. Since 22 September 2025 most goods are 5% or 18%.
-
Default HSN code: the goods code printed on invoices for products without their own. 4 digits up to ₹5 crore turnover, 6 above.
A different rate or HSN code for one product is set on that product’s page in Products.
Save
Select Save in the bar at the top. You will see “Tax settings saved”. The bar stays put when you switch tabs, so you can change a rule and an invoice number and save both at once.
Invoice numbers tab
Invoice numbers
- Starts with: letters, numbers,
/and-. Write{FY}where you want the year:INV/{FY}/givesINV/26-27/0001. - Next number: moving from another system? Start where your old invoices stopped. You can only go up, never back to a number that is already used.
- Start again at 1 every April: on by default. A new financial year starts on 1 April; most shops restart the count then and keep the year in the number.
The line under the fields shows your next invoice number. These are the same numbers the GST invoices app uses; if the app is not installed yet, the page says so and links to Apps. Separate numbers for exports, credit notes or business buyers are set in Apps → GST invoices → Settings.
E-invoicing (IRN)
Not built yet. Businesses above ₹5 crore turnover must get an IRN and QR code from the government portal for B2B invoices; for now, do that on the e-invoice portal yourself.
Save
Select Save in the bar at the top. You will see “Tax settings saved”.

Common questions
I changed the legal name here and it changed in the GST invoices app too. Is that right? Yes. Both screens edit the same details, so your invoices always match.
Does changing the default rate change old orders? No. Each order keeps the tax it was placed with. The new rate applies to orders placed after you save.
