How to Set Up GST Rates in Tally: Complete Configuration Guide

GST rate setup in TallyPrime involves enabling GST under F11, creating tax ledgers for each rate (5%, 12%, 18%, 28%), and assigning them to stock items or parties. Rates auto-calculate based on item classification and buyer location.

Why GST Rate Setup Matters in TallyPrime

Setting up GST rates correctly in TallyPrime is the foundation of compliant invoicing and accurate tax reporting. Without proper rate configuration, your invoices will either under-tax or over-tax customers, leading to reconciliation errors, GSTR-1 mismatches, and potential GST audit flags. TallyPrime automates tax calculation once rates are assigned, reducing manual errors and saving hours during month-end GSTR filing. Since TallyPrime has been trusted by 35 million users across India, its GST engine is built to handle the complexity of multi-rate taxation across states, categories, and exemptions.

Prerequisites Before Setting Up GST Rates

Before you configure GST rates, ensure the following are in place:

• TallyPrime version 6.x or later installed (includes native GST + GSTR reconciliation).
• A valid GST registration number (GSTIN) for your company.
• Basic knowledge of your product or service categories and their applicable GST slabs.
• A list of states where you sell, to determine SGST/CGST vs IGST application.
• Backup of your Tally data (use Alt+Y > Data > Backup before making changes).

Step 1: Enable GST in TallyPrime Features

The first step is to enable GST in your company's Tally configuration. Open TallyPrime and follow this exact path:

Gateway of Tally > F11 (Features) > F1 (Statutory) > GST > Yes (Enable GST)

Once you select "Yes", TallyPrime will activate GST-related fields, reports, and calculations company-wide. You will see new options appear in the menu, such as GSTR-1, GSTR-2B, and GSTR-3B under Display More Reports. If you have already configured a company without GST, enabling it retroactively will not alter past invoices, but all future transactions will include GST fields.

Step 2: Create Tax Ledgers for Each GST Rate

Tax ledgers are the backbone of GST rate management. Each rate (5%, 12%, 18%, 28%) and each tax type (SGST, CGST, IGST) requires its own ledger. Here is how to create them:

Gateway of Tally > Masters > Accounts > Tax Ledgers > Create New

For example, create a ledger named "SGST 18%" with these details:

• Name: SGST 18%
• Under: (select "Duties and Taxes" or "Tax Payable")
• Type: Tax (GST)
• Tax Rate: 18%
• Tax Type: SGST

Repeat this for CGST 18%, IGST 18%, and all other applicable rates (5%, 12%, 28%). The naming convention "SGST 18%" makes it easy to identify and audit later. Do not mix rates in a single ledger; TallyPrime requires one ledger per rate to calculate and report accurately.

Step 3: Assign GST Rates to Stock Items

Once tax ledgers are created, assign them to your stock items. This ensures that every invoice automatically applies the correct rate.

Gateway of Tally > Masters > Stock Items > select or create an item > F2 (Edit)

In the stock item form, you will see a field called "Tax Rate" or "Applicable Tax". Select the appropriate tax ledger (e.g., "SGST 18% + CGST 18%" for intra-state sales). For inter-state sales, TallyPrime will automatically switch to IGST if the buyer is in a different state.

Worked Example: Setting Up a 18% Rate for Electronics

Suppose you sell mobile phones (classified under 18% GST). Here is the complete setup:

Step	Action	Details
1	Create Tax Ledgers	SGST 18%, CGST 18%, IGST 18%
2	Create Stock Item	Item Name: Mobile Phone XYZ, Category: Electronics
3	Assign Tax Rate	Select "SGST 18% + CGST 18%" for intra-state, IGST auto-applies for inter-state
4	Create Invoice	Qty: 1, Rate: Rs 10,000, Tax auto-calculated: Rs 3,600 (18%), Total: Rs 13,600
5	Verify in GSTR-1	Alt+G > GSTR-1 > Check line items and tax amounts match

Understanding Multi-Rate GST Configuration

India's GST structure includes four main rates: 0% (essentials like food grains), 5% (common goods like tea, sugar), 12% (mid-range items like cosmetics), 18% (standard rate for most goods), and 28% (luxury items like cars, air conditioners). Your business may sell items across multiple rates. TallyPrime handles this by allowing you to assign different rates to different items. When you create an invoice, the system looks up the tax ledger assigned to each line item and applies the correct rate automatically. This multi-rate capability is critical for businesses like retailers, manufacturers, or wholesalers that deal with diverse product categories.

SGST, CGST, and IGST: When to Use Each

TallyPrime automatically determines which tax type to apply based on the buyer's location:

• SGST + CGST: Intra-state sales (buyer in same state as your company). Both are applied at the same rate, e.g., 9% SGST + 9% CGST = 18% total.
• IGST: Inter-state sales (buyer in a different state). A single IGST is applied at the full rate, e.g., 18% IGST for the same item.
• Exempt or 0%: Essential items, services, or specific exemptions under GST law.

You do not need to manually select SGST vs IGST on each invoice. When you enter the buyer's GSTIN or address, TallyPrime checks the state code and automatically switches between SGST+CGST and IGST. This is one of the most powerful features of TallyPrime's GST engine.

Setting Up HSN and SAC Codes

HSN (Harmonized System of Nomenclature) codes are 6-digit codes that classify goods and determine their GST rate. SAC (Service Accounting Code) codes do the same for services. Assigning these codes to your stock items is not mandatory for basic invoicing, but it is required for GSTR-1 filing and e-invoicing. To add HSN to a stock item:

Gateway of Tally > Masters > Stock Items > Edit Item > Add HSN Code field

For example, mobile phones have HSN code 8517.62, which falls under 18% GST. Assigning the correct HSN ensures that your GSTR-1 report is accurate and matches the GST portal's expectations. You can download the official HSN list from the GST portal.

Handling Exemptions and Zero-Rated Items

Some items are exempt from GST (no tax collected but input credit not available) or zero-rated (no tax collected but input credit available). Examples include:

• Exempt: Services like education, healthcare (private).
• Zero-rated: Exports, certain food items.

To set up a zero-rated or exempt item, create a tax ledger with 0% rate and assign it to the item. In GSTR-1, these will appear in separate sections (Exempt, Zero-Rated, or Nil-Rated), and TallyPrime will handle the reporting correctly. This is especially important if you export goods, as zero-rated supplies allow you to claim input credit while charging no tax.

Verifying GST Rate Setup with a Test Invoice

Before going live, always test your GST rate setup by creating a sample invoice. Here is how:

1. Go to Gateway of Tally > Transactions > Invoicing > Sales.
2. Enter a customer, select a stock item with assigned tax rate.
3. Enter quantity and rate; TallyPrime will auto-calculate tax.
4. Verify the tax amount matches your expectation (e.g., 18% of Rs 10,000 = Rs 1,800 SGST + Rs 1,800 CGST).
5. Save the invoice.
6. Go to Alt+G > GSTR-1 and check that the invoice appears with correct tax amounts.

If the tax amount is incorrect, go back to the stock item and verify the assigned tax ledger. If it is still wrong, check that the tax ledger itself has the correct rate under Masters > Accounts > Tax Ledgers.

Common GST Rate Setup Mistakes to Avoid

Even experienced Tally users make these errors:

• Mixing rates in one ledger: Do not create a ledger called "All Taxes 18%". Create separate SGST 18%, CGST 18%, IGST 18% ledgers.
• Forgetting to enable GST first: If GST is not enabled in F11, tax fields will not appear, and rates will not calculate.
• Assigning wrong rate to item: Always double-check the HSN code and applicable rate before assigning a tax ledger to a stock item.
• Not backing up before changes: Large-scale rate changes can affect historical invoices. Always backup first using Alt+Y.
• Ignoring state-wise rate differences: Some items have different rates in different states (e.g., certain foods). TallyPrime does not auto-adjust by state; you must manage this manually via different items or ledgers.

GST Rate Updates and Compliance

GST rates occasionally change due to policy updates. The government announces changes on the GST portal, usually effective from a specific date. When a rate change occurs, you must update your tax ledgers in TallyPrime. Go to Masters > Accounts > Tax Ledgers > select ledger > Edit and change the rate. Ensure the change is applied from the correct effective date. TallyPrime does not have a built-in rate history feature, so you may want to create new ledgers (e.g., "SGST 18% Old", "SGST 18% New") and use them for invoices before and after the change date. This makes auditing easier.

Integration with GSTR-1 Filing

Once your GST rates are set up correctly, GSTR-1 filing becomes straightforward. The GSTR-1 report pulls data directly from your invoices, using the tax ledgers and rates you assigned. Go to Alt+G > GSTR-1 to view your monthly summary. The report shows sales by tax rate, HSN code, and buyer type. If your rates are misconfigured, the GSTR-1 will have errors, and you will need to amend it on the GST portal. Proper rate setup at the start prevents costly amendments later.

Connecting to e-Invoicing with Correct Rates

If you use e-invoicing in TallyPrime, the IRN (Invoice Reference Number) generation depends on accurate GST rates. The IRP (Invoice Registration Portal) validates your invoice, including tax amounts, before issuing an IRN. If rates are wrong, the e-invoice will fail validation. Ensure that GST is enabled and rates are correctly assigned before enabling e-invoicing. TallyPrime 6.x includes integrated e-invoicing, so once rates are set, invoices flow automatically to the portal.
