GST Setup Done But Invoices Still Show Zero Tax — What You’re Missing

You Did Everything Right… Or Did You?

You enabled GST in Tally Prime. You filled in your GSTIN. You even created tax ledgers. But when you create a sales invoice — the tax amount shows zero.

Frustrating, right?

Don’t worry. This is one of the most common problems beginners face in Tally Prime. And the good news is — the fix is usually simple, once you know where to look.

Let’s go step by step.

Why Does This Happen?

GST in Tally Prime is not just one setting. It works like a chain:

Company GST Setting
        ↓
Stock Item / Ledger GST Setting
        ↓
Party Ledger GST Setting
        ↓
Tax Ledger in Invoice
        ↓
✅ Tax Appears Correctly

If any one link in this chain is broken — your invoice will show zero tax.

Let’s check each link one by one.

Reason 1: GST Is Enabled in Company But Features Are Not Activated Properly

What happens:

You go to company settings, enable GST, add your GSTIN — but miss one small checkbox.

How to check:

1. Press F11 (Features) in Tally Prime
2. Go to Taxation
3. Check if “Enable Goods and Services Tax (GST)” is set to Yes
4. Also check “Set/Alter GST Details” is Yes
5. Make sure your State, GSTIN, and Registration Type are correctly filled

Example:

Ramesh runs a shop in Delhi. He enabled GST but forgot to select his State as “Delhi.” Because of this, Tally couldn’t calculate CGST + SGST correctly and showed zero tax.

✅ Fix: Press F11 → Taxation → Re-enter your state and GSTIN properly.

Reason 2: Your Stock Item Has No GST Rate Assigned

This is the most common reason for zero tax on invoices.

When you create a stock item (the product you sell), you must also tell Tally — what GST rate applies to this item.

If you skip that step, Tally doesn’t know what tax to charge. So it charges nothing.

How to check:

1. Go to Gateway of Tally → Masters → Stock Items
2. Open the stock item you used in the invoice
3. Scroll down to GST Details
4. Check if HSN Code and Tax Rate are filled

Example:

Priya sells mobile phone covers. She created the stock item “Phone Cover” but never added HSN Code 3926 or the 18% GST rate. Every invoice she made showed ₹0 tax — even though she was charging customers 18%.

✅ Fix: Edit the stock item → Add HSN Code + select correct Tax Slab (5%, 12%, 18%, 28%)

Step to add GST in Stock Item:

Gateway of Tally
→ Masters
→ Stock Items
→ Select your item → Press Enter
→ Scroll to GST Details
→ Set "Is GST Applicable" = Applicable
→ Enter HSN Code
→ Enter Tax Rate (e.g., 18%)
→ Save with Ctrl+A

Reason 3: Tax Ledger Is Not Added in the Invoice

Even if your stock item has the correct GST rate — if you don’t add a tax ledger in the invoice, the tax won’t appear.

Think of it like this:

Tally calculated the tax amount in the background. But you didn’t give it a “box” to put that amount in. So it stays hidden.

How to check:

Open a sales invoice and look at the bottom section. You should see ledger rows for:

• CGST (for local sales)
• SGST (for local sales)
• OR IGST (for interstate sales)

If those rows are missing — that’s your problem.

How to fix:

While creating the invoice:

1. After adding your stock item, press Enter to go to the ledger section below
2. Add a new row → Select CGST ledger
3. Add another row → Select SGST ledger
4. Tally will automatically fill the tax amount

✅ Once you add these ledgers, the tax will appear instantly.

Reason 4: Your Tax Ledger Is Created Under the Wrong Group

You created CGST and SGST ledgers — but you made them under “Indirect Expenses” or “Current Liabilities” instead of the correct group.

Tally only recognizes tax ledgers that are under the group “Duties & Taxes.”

How to check:

1. Go to Gateway of Tally → Masters → Ledgers
2. Open your CGST ledger
3. Check the “Under” field — it must say Duties & Taxes
4. Also check “Type of Duty/Tax” = GST
5. And “Tax Type” = Central Tax (for CGST) or State Tax (for SGST)

Example:

Amit created a ledger called “CGST Payable” but put it under “Current Liabilities.” Tally didn’t recognize it as a tax ledger. His invoices kept showing zero even after adding the ledger in the invoice.

✅ Fix: Edit the ledger → Change “Under” to Duties & Taxes → Save

Reason 5: GST Is Not Enabled for the Sales Ledger

Yes — your Sales ledger also needs GST to be turned on!

Many people forget this completely.

How to fix:

1. Go to Masters → Ledgers → Sales (or your sales ledger)
2. Open it and check “Is GST Applicable” = Applicable
3. Set the correct Nature of Transaction (e.g., Sales Taxable)

Gateway of Tally
→ Ledgers
→ Open Sales Ledger
→ GST Applicability = Applicable
→ Nature of Transaction = Sales Taxable
→ Save

Reason 6: Party Ledger Has Wrong Registration Type

If your customer’s ledger is set as Unregistered or Consumer when they are actually a Registered Business — Tally may calculate tax differently or not show it the way you expect.

How to check:

1. Open the party (customer) ledger
2. Check GST Registration Type
3. If they are a GST-registered business → Select Regular
4. If they are an end consumer → Select Consumer
5. Also make sure their GSTIN is correctly entered

Quick Checklist — Run This Every Time Tax Shows Zero

Before panicking, go through this list:

#	What to Check	Where to Check
1	GST enabled in company?	F11 → Taxation
2	HSN + Tax Rate in stock item?	Masters → Stock Items
3	CGST/SGST ledger added in invoice?	Inside the invoice
4	Tax ledger under “Duties & Taxes”?	Masters → Ledgers
5	Sales ledger GST = Applicable?	Masters → Ledgers → Sales
6	Party ledger registration type correct?	Masters → Ledgers → Party

Let’s See a Full Working Example

Situation: Sunita sells handmade candles (GST 12%) from her shop in Lucknow to a local customer.

Her mistake: She created the stock item “Scented Candle” but never added HSN code or tax rate.

Result: Every invoice showed ₹0 GST even though candles attract 12%.

How she fixed it:

1. Went to Masters → Stock Items → Scented Candle
2. Added HSN Code: 3406
3. Set Tax Rate: 12%
4. Saved the item
5. Opened a new invoice — added the candle — added CGST and SGST ledgers at the bottom
6. Tax appeared automatically — ₹72 on a ₹600 sale (6% CGST + 6% SGST)

Problem solved in under 5 minutes.

One More Tip — Use Voucher Class for Automatic Tax

If you don’t want to manually add CGST/SGST ledgers every single time in every invoice, you can set up a Voucher Class in Tally Prime.

With Voucher Class:

• Tax ledgers get added automatically
• You just enter the item and quantity
• Tally does the rest

This is especially helpful if you make 20-30 invoices per day.

(We’ll cover Voucher Class setup in a separate detailed post.)

Conclusion

Zero tax on invoices is never a Tally glitch — it’s always a setup gap. And now you know exactly where to look.

To recap the 6 things to check:

1. Company GST settings (F11)
2. Stock item HSN and tax rate
3. Tax ledgers added inside the invoice
4. Tax ledgers created under Duties & Taxes
5. Sales ledger GST applicability
6. Party ledger registration type

Fix any one of these — and your tax will start showing correctly.
