What is TaxCopilot AI — and what is GST Reconciliation Software?
GST Reconciliation Software automates the matching of your Purchase Register against government-issued GSTR-2B (and GSTR-2A) data to identify mismatches, recover eligible Input Tax Credit (ITC), and maintain GST compliance — eliminating the need for manual VLOOKUP-based reconciliation in Excel.

TaxCopilot is an AI-powered GST Reconciliation engine built specifically for Indian Chartered Accountants. It processes thousands of invoice rows in seconds, categorizing them into Exact Matches, Tolerant Matches, and Missing invoices. The platform then calculates your Total ITC at Risk in real-time and uniquely enables CAs to send AI-drafted Hinglish WhatsApp reminders to non-compliant vendors — directly from the dashboard. Exports to Excel are available in one click, and the tool is compatible with CSV exports from major ERP systems including Tally, Zoho Books, and SAP.

GSTR-2A vs GSTR-2B Reconciliation — What's the Difference?

Both GSTR-2A and GSTR-2B are ITC-related statements — but they serve different purposes. TaxCopilot handles both.

GSTR-2A Reconciliation

GSTR-2A is a dynamic, auto-populated statement that updates continuously as your suppliers file GSTR-1. Reconciling your Purchase Register against GSTR-2A is ideal for intra-month ITC tracking before GSTR-2B is finalized. TaxCopilot supports GSTR-2A CSV uploads and flags discrepancies in the same workflow.

GSTR-2B Reconciliation

GSTR-2B is a static, locked statement generated on the 14th of each month based on your suppliers' GSTR-1 filings. It is the definitive source for claiming ITC in your GSTR-3B. Reconciling your Purchase Register against GSTR-2B using TaxCopilot ensures you never over- or under-claim credit.

TaxCopilot's AI engine handles both GSTR-2A vs Purchase Register matching and GSTR-2B vs Purchase Register reconciliation — so your firm is covered for every use case, every month.

GST Compliance Management & ERP Integration

TaxCopilot goes beyond reconciliation — it is a complete GST compliance management tool that fits directly into your existing accounting workflow.

🛡️ GST Compliance Management

Maintain GST compliance month after month with a structured workflow: reconcile → identify missing invoices → chase vendors → confirm ITC → export. The AI Copilot Chat generates client-ready compliance summaries directly from your live dashboard data. Never miss a deadline or mis-claim ITC again.

🔗 ERP & Accounting Software Integration

TaxCopilot is designed to work alongside your existing ERP system. Import Purchase Register CSVs exported directly from Tally ERP, Zoho Books, SAP, QuickBooks India, Busy Accounting, and any other software that supports CSV output. The dynamic column-mapping UI means no fixed template — map your headers once and reconcile in seconds.

🔒 Data Privacy & Security

Your financial data never leaves your control. TaxCopilot processes reconciliation on a multi-tenant, CA-specific architecture — each firm's data is isolated. Unlike desktop-based offline GST reconciliation tools, TaxCopilot's cloud architecture means your reconciliation history is accessible from anywhere, while remaining private to your firm.

Frequently Asked Questions

Everything you need to know about AI-powered GST reconciliation.

What is GST Reconciliation Software and why do CAs need it? +
GST Reconciliation Software automates the comparison of your Purchase Register with GSTR-2B or GSTR-2A data provided by the government portal. Without it, CAs must use complex Excel VLOOKUPs to manually match thousands of invoice rows — a process prone to errors and missed ITC. GST Reconciliation Software like TaxCopilot handles this automatically, flagging mismatches and calculating Total Input Tax Credit (ITC) at Risk in seconds, ensuring accurate GSTR-3B filing and maximum ITC recovery.
Does TaxCopilot support GSTR-2A vs Purchase Register matching? +
Yes. TaxCopilot supports both GSTR-2B vs Purchase Register reconciliation and GSTR-2A vs Purchase Register matching. GSTR-2A is the dynamic real-time statement useful for intra-month ITC tracking, while GSTR-2B is the static, finalized statement used for GSTR-3B filing. You can upload either CSV format and run the same AI matching workflow.
How does TaxCopilot calculate ITC at Risk? +
During Input Tax Credit (ITC) reconciliation, TaxCopilot identifies all invoices that appear in your Purchase Register but are absent from GSTR-2B (or vice versa). For each such invoice, the system extracts the IGST, CGST, and SGST values and sums them into a Total ITC at Risk figure displayed on your dashboard. This tells you exactly how much credit you could lose if vendors fail to file their GSTR-1 — so you can chase them proactively.
Does TaxCopilot integrate with Tally, SAP, or other ERP systems? +
TaxCopilot accepts CSV exports from any ERP or accounting software — including Tally ERP, Zoho Books, SAP Business One, QuickBooks India, Busy Accounting, and Marg ERP. There is no fixed template. The dynamic column-mapping UI lets you select which column in your CSV corresponds to Invoice Number, GSTIN, Taxable Value, Tax Amount, and so on. You map headers once, and the engine handles the rest. This makes TaxCopilot a seamless addition to any existing ERP workflow.
How does TaxCopilot handle round-off differences? +
Our backend engine uses a Tolerant Match logic. If the invoice numbers match but the taxable value is off by minor decimal rounding (e.g., ₹2.00 difference), the system intelligently groups them into the 'Matched Tolerant' bucket rather than throwing a hard mismatch error — saving you from chasing vendors for rounding discrepancies.
Is TaxCopilot safe for sensitive GST data? Is there an offline version? +
TaxCopilot is a cloud-based GST Reconciliation Software built on a multi-tenant, firm-isolated architecture — meaning your client's financial data is never mixed with other firms' data and is not used to train any AI models. While TaxCopilot is not a desktop offline tool, all reconciliation processing happens securely on our servers and your data is accessible only to your firm's authorized users. If your firm has strict data-residency requirements, please contact our team to discuss options.
How does TaxCopilot help with ongoing GST compliance management? +
Beyond reconciliation, TaxCopilot functions as a GST compliance management platform. The AI Copilot Chat can generate client-ready compliance summaries from your live dashboard, identify vendors with a pattern of late GSTR-1 filings, and draft WhatsApp or email follow-up messages. Monthly reconciliation history is saved per client, so you can track ITC recovery trends over time and demonstrate compliance to auditors.
How does the WhatsApp Vendor Follow-up drafter work? +
When an invoice is Missing in 2B, you click 'Follow Up'. TaxCopilot sends the invoice details securely to Gemini AI, which drafts a professional Hinglish reminder. You then click one button to open WhatsApp Web and send it directly to the vendor — helping you recover your client's ITC without writing a single word manually.
