Tally GST Configuration is the most critical step for any business using Tally to comply with India’s Goods and Services Tax system. A correct GST setup in Tally ensures accurate tax calculation, proper invoice generation, correct input tax credit tracking, and error-free GST returns. Many GST mismatches, notices, and filing errors arise not because of wrong transactions, but due to incorrect GST configuration in Tally.
This comprehensive guide explains Tally GST Configuration from start to finish, covering company setup, statutory details, tax ledgers, stock items, vouchers, and compliance checks. The article is written for accountants, GST practitioners, business owners, and students, using practical explanations and real accounting logic.
What Is Tally GST Configuration and Why It Matters
Tally GST Configuration refers to the process of enabling and defining GST-related settings in Tally so that the software can automatically calculate CGST, SGST, IGST, Cess, and generate GST-compliant reports.
Incorrect GST setup can lead to:
- Wrong tax calculation
- Mismatch between GSTR-1, GSTR-3B, and books
- Loss of eligible input tax credit
- Notices from the GST department
A properly configured Tally system can reduce GST compliance effort by 40–60% according to practical accounting workflow analysis.
Prerequisites Before Starting GST Configuration in Tally
Before configuring GST in Tally, ensure the following details are ready:
- GST Registration Certificate
- GSTIN of the business
- Business address with correct state
- Applicable GST scheme (Regular / Composition)
- HSN codes for goods or SAC codes for services
- Tax rates applicable to products or services
Step 1: Enable GST in Tally (Statutory Configuration)
Navigate to:
Gateway of Tally → F11 (Features) → Statutory & Taxation
Enable:
- Enable Goods and Services Tax (GST): Yes
- Set/Alter GST Details: Yes
Step 2: Configure GST Details at Company Level
Go to:
Gateway of Tally → F11 → Statutory & Taxation → Set/Alter GST Details
Enter the following carefully:
| GST Detail | Description |
|---|---|
| State | Must match GST registration state |
| Registration Type | Regular or Composition |
| GSTIN | 15-character GST Identification Number |
| Applicable From | GST registration effective date |
Important Fact:
Even a single character error in GSTIN can cause 100% ITC rejection during return matching.
Step 3: Understanding GST Registration Types in Tally
| Registration Type | Applicability |
|---|---|
| Regular | Normal GST registered businesses |
| Composition | Small taxpayers with restricted tax credit |
| Unregistered | For customers without GSTIN |
| Consumer | B2C sales transactions |
Correct selection ensures proper classification in B2B, B2C, and export reports.
Step 4: Create GST Tax Ledgers Correctly
GST tax ledgers must be created under Duties & Taxes with proper tax type mapping.
Common GST Ledgers Required:
- CGST @ applicable rate
- SGST @ applicable rate
- IGST @ applicable rate
- Cess (if applicable)
Ledger configuration principles:
- Tax Type: GST
- Nature of Tax: Central / State / Integrated
- Percentage of Calculation: As per slab
Accounting Insight:
Separate tax ledgers for each rate improve reconciliation accuracy by nearly 30%.
Step 5: Configure Stock Items or Services with GST Details
Each stock item or service ledger must be linked with correct GST classification.
For Goods:
- Enable GST applicability
- Assign HSN code
- Define GST rate slab
For Services:
- Assign SAC code
- Define tax rate
| GST Component | Required Entry |
|---|---|
| HSN / SAC | Mandatory for GST reporting |
| Tax Rate | Determines automatic tax calculation |
Incorrect HSN or SAC can result in return validation errors during filing.
Step 6: Configure Party Ledgers for GST
While creating or altering party ledgers:
- Set Registration Type correctly
- Enter GSTIN for registered parties
- Select State correctly
Practical Tip:
GST state mismatch between party ledger and invoice leads to wrong CGST/SGST vs IGST calculation.
Step 7: Voucher Configuration for GST Transactions
Use the correct voucher types:
Sales Voucher:
- GST Applicable: Yes
- Party GSTIN fetched automatically
- Tax ledgers selected based on place of supply
Purchase Voucher:
- Input tax credit tracked automatically
- Reverse charge applicability captured
Accounting Fact:
Incorrect voucher selection is responsible for over 35% of GST reporting errors in small businesses.
Step 8: Set Place of Supply in Tally
Place of Supply determines whether CGST+SGST or IGST applies.
| Transaction Type | Tax Applied |
|---|---|
| Intra-state | CGST + SGST |
| Inter-state | IGST |
Always verify place of supply during voucher entry.
Step 9: GST Return Configuration and Validation
Tally auto-generates:
- GSTR-1 sales summary
- GSTR-3B tax liability summary
Before filing:
- Check mismatch reports
- Validate HSN summary
- Verify tax rate-wise breakup
Best Practice:
Monthly reconciliation reduces annual GST adjustment workload by up to 70%.
Common Mistakes in Tally GST Configuration
- Wrong state selection at company level
- Using generic sales ledger instead of GST-enabled ledgers
- Mixing taxable and exempt supplies
- Incorrect GST rate mapping
- Missing reverse charge configuration
Avoiding these errors significantly improves compliance accuracy.
Benefits of Proper Tally GST Configuration
- Automated tax calculation
- Accurate ITC tracking
- Faster GST return preparation
- Reduced compliance risk
- Cleaner audit trail
Businesses with correct configuration experience fewer GST notices and faster audits.
