Connected GST in TallyPrime: Real-Time GSTR Reconciliation & e-Invoice Filing

Connected GST in TallyPrime 6.x is a real-time integration feature that syncs your sales and purchase invoices with the GST portal, auto-reconciles GSTR-1 and GSTR-2B, and enables one-click e-invoice filing with IRN generation. It requires active TSS and internet connectivity.

What is Connected GST in TallyPrime?

Connected GST is a cloud-integrated feature introduced in TallyPrime 6.x that bridges your accounting software with the GST portal in real-time. Instead of manually exporting data, reconciling offline, and uploading to the portal, Connected GST automates the entire workflow. Your invoices flow directly to the GST portal, GSTR-1 (outward supplies) and GSTR-2B (inward supplies) data sync automatically, and e-invoices are generated with IRN (Invoice Reference Number) and QR codes on the fly.

This feature is especially valuable for businesses in Purnea, Bihar, and across India that file GST returns monthly. It eliminates data entry errors, reduces compliance risk, and cuts the time spent on GST administration by up to 70 percent. Global IT Care, a Tally 3 Star Certified Partner since 2010, has helped hundreds of Purnea-based traders and SMEs implement Connected GST to stay audit-ready year-round.

Why Connected GST Matters for Your Business

GST filing deadlines are strict. GSTR-3B is due on the 20th of the month following the invoice month for regular taxpayers. A single mismatch between your books and the portal can trigger a notice, delay your ITC (Input Tax Credit) claim, or invite scrutiny. Connected GST removes that risk by ensuring your data is always in sync with the portal.

Before Connected GST, businesses had to export data from TallyPrime, upload it to the GST portal, wait for portal validation, manually reconcile mismatches, and then re-upload. This multi-step process was error-prone and time-consuming. Connected GST collapses all of this into a single, automated workflow. Your invoices are validated in real-time, GSTR-2B data is matched automatically, and e-invoices are generated instantly with IRN and QR codes.

How to Enable Connected GST in TallyPrime

Enabling Connected GST is straightforward. First, ensure you are running TallyPrime 6.x or later and that your Technical Support Services (TSS) is active. TSS is mandatory for Connected GST because it provides the secure connection to the GST portal and e-invoice infrastructure.

Follow these steps:

1. Open TallyPrime and go to Gateway of Tally.
2. Press F11 to open Features Configuration.
3. Navigate to GST and select Enable GST.
4. In the GST settings, enable Connected Services.
5. Enter your GST Registration Number (GSTIN) and authenticate using your GST portal credentials.
6. Save and exit. TallyPrime will now sync with the portal.

If you encounter a "License Server Error" or "Connection Failed" message, check your internet connection and verify that the correct IP and port are set in TallyPrime Server Monitor. Once Connected GST is enabled, all new invoices created in TallyPrime will be transmitted to the GST portal in real-time.

Real-Time GSTR-1 Reconciliation

GSTR-1 is your outward supply return, listing all sales invoices issued during the month. With Connected GST, every invoice you create in TallyPrime is automatically transmitted to the GST portal and appears in your GSTR-1 within minutes. This real-time sync means you can verify your GSTR-1 before the filing deadline and correct any errors on the spot.

To view your GSTR-1 reconciliation in TallyPrime, go to Gateway of Tally, select Display More Reports, then GST Reports, and choose GSTR-1. TallyPrime will show you a side-by-side comparison of invoices in your books versus those on the portal. Any discrepancies are flagged, allowing you to investigate and correct them immediately.

GSTR-2B Auto-Matching and Reconciliation

GSTR-2B is the most powerful feature of Connected GST. It shows all purchases reported by your suppliers on the GST portal. Instead of manually downloading GSTR-2B from the portal and comparing it line-by-line with your purchase invoices, Connected GST does this automatically.

When you enable Connected GST, TallyPrime pulls GSTR-2B data from the portal and matches it against your purchase ledger. Invoices that match are marked as reconciled. Invoices in GSTR-2B that are not in your books are flagged for investigation, and invoices in your books that are not in GSTR-2B are also highlighted. This reconciliation happens in the background, so you always have an up-to-date picture of your ITC eligibility before filing GSTR-3B.

This is critical because ITC (Input Tax Credit) is only available for purchases that appear in GSTR-2B. If a supplier has not filed their GSTR-1, their invoice will not appear in GSTR-2B, and you cannot claim ITC for it until they do. Connected GST alerts you to these gaps in real-time, so you can follow up with suppliers and ensure timely filing.

Automated e-Invoice Generation and IRN

e-Invoicing is mandatory for businesses with turnover above Rs 20 lakhs. With Connected GST enabled, every invoice you create in TallyPrime is automatically sent to the IRP (Invoice Registration Portal) for IRN (Invoice Reference Number) generation. The IRN and QR code are returned instantly and embedded in the invoice PDF.

You do not need to manually upload invoices to the IRP or copy-paste IRNs. TallyPrime handles it all. The QR code on the e-invoice can be scanned by your customer, and the invoice data flows automatically to their GSTR-2B, eliminating manual data entry on their end as well.

To verify that e-invoicing is enabled, go to Gateway of Tally, press F11, navigate to GST, and confirm that e-Invoicing is set to Yes. Your TSS must be active for this to work.

Worked Example: GSTR-1 and GSTR-2B Reconciliation

Let us walk through a real scenario. Suppose you are a wholesale trader in Purnea with a monthly turnover of Rs 50 lakhs. In January 2026, you issue 120 sales invoices totaling Rs 50 lakhs (including GST). You also receive 85 purchase invoices totaling Rs 35 lakhs (including GST) from suppliers.

Without Connected GST, you would:

1. Export sales data from TallyPrime and upload to the GST portal for GSTR-1 filing.
2. Download GSTR-2B from the portal on the 15th of February.
3. Manually compare your 85 purchase invoices against GSTR-2B entries.
4. Identify 8 invoices that are in your books but not in GSTR-2B (suppliers have not filed yet).
5. Identify 3 invoices in GSTR-2B that you had missed recording in TallyPrime.
6. Correct your books, re-export, and re-upload to the portal.
7. File GSTR-3B with the corrected data by the 20th of February.

This process takes 8-12 hours and is error-prone. With Connected GST, here is what happens:

1. You create all 120 sales invoices in TallyPrime throughout January. Each is transmitted to the portal in real-time.
2. You create all 85 purchase invoices in TallyPrime. Each is matched against GSTR-2B as it arrives on the portal.
3. By January 31st, you log into TallyPrime and run the GSTR-2B Reconciliation Report. It shows all 85 invoices matched, with 8 flagged as "Not Yet in GSTR-2B" (suppliers have not filed).
4. You follow up with those 8 suppliers to ensure they file by February 15th.
5. By February 15th, all 8 invoices appear in GSTR-2B, and TallyPrime auto-updates the reconciliation status.
6. You file GSTR-3B on February 19th with 100 percent confidence that your data matches the portal.

Time saved: 6-10 hours. Risk eliminated: 99 percent. This is the power of Connected GST.

GSTR-3B Filing Timeline and Connected GST

GSTR-3B is the monthly GST return, due on the 20th of the following month for regular taxpayers. Connected GST does not file GSTR-3B automatically, but it prepares all the data you need to file it confidently.

Here is the timeline:

• Days 1-31 of the month: Create invoices in TallyPrime. Connected GST syncs them to the portal in real-time.
• Day 15 of the next month: GSTR-2B is released on the portal. Connected GST auto-matches your purchases against it.
• Day 15-19 of the next month: Review GSTR-1 and GSTR-2B reconciliation reports in TallyPrime. Correct any mismatches.
• Day 20 of the next month: File GSTR-3B on the GST portal using the data prepared by TallyPrime.

Connected GST ensures that by day 19, your books are 100 percent aligned with the portal, so filing on day 20 is a formality.

Connected GST and TallyPrime on Cloud

If you use TallyPrime on Cloud, Connected GST works seamlessly. TallyPrime on Cloud is hosted on secure servers with 99.9 percent uptime, daily backups, and RDP access from Windows, Mac, Linux, Android, and iOS devices. Connected GST syncs your data to the GST portal regardless of where you access TallyPrime from.

TallyPrime on Cloud pricing starts at Rs 175-290 per user per month (bring-your-own-licence) or Rs 899-1,299 per month (with licence included). For businesses in Purnea that want the flexibility of cloud access without the complexity of on-premises servers, TallyPrime on Cloud with Connected GST is an excellent choice.

TSS and Connected GST: What You Need to Know

Technical Support Services (TSS) is the gateway to Connected GST. Without active TSS, you cannot sync with the GST portal, generate IRNs, or access e-invoicing. TSS renewal costs Rs 4,500 per year for TallyPrime Silver and Rs 13,500 per year for TallyPrime Gold (plus 18 percent GST).

Every new TallyPrime licence includes 1 year of TSS free. After that, renewal is optional but highly recommended if you use Connected GST. Early TSS renewal adds approximately 1 free month, and 2-year renewals offer approximately 10 percent discount.

If your TSS expires, TallyPrime continues to work, but you lose access to Connected GST, e-invoicing, and portal sync. You can still create invoices and file GST returns manually, but the automated features are unavailable until TSS is renewed.

Common Connected GST Issues and Fixes

If Connected GST is not syncing, check the following:

• Internet Connection: Connected GST requires a stable, continuous internet connection. Check your network status and ensure your firewall is not blocking TallyPrime ports.
• TSS Status: Verify that TSS is active. Go to Gateway of Tally, press F1 (Help), and check License and Subscription. If TSS has expired, renew it immediately.
• GSTIN Authentication: Confirm that your GSTIN is correctly entered and authenticated in TallyPrime. Go to F11, GST, and verify your GST Registration Number.
• License Server Error: If you see "License Server Error," open TallyPrime Server Monitor and ensure the correct IP address and port are set. Restart the server.
• Data Repair: If invoices are not syncing, perform a data repair. Go to Gateway of Tally, press Alt+Y (Data), and select Repair. Always back up your company data first.

TallyPrime Editions and Connected GST Availability

Connected GST is available in both TallyPrime Silver and TallyPrime Gold editions, provided TSS is active. TallyPrime Silver (single user, perpetual licence) costs Rs 22,500 plus 18 percent GST. TallyPrime Gold (unlimited users on LAN, perpetual licence) costs Rs 67,500 plus 18 percent GST. Upgrade from Silver to Gold is Rs 45,000 plus GST.
