Difference Between GSTR 2A and 2B with Examples

If you’re running a small or micro business in India, knowing the difference between GSTR 2A and 2B is essential for your monthly GST filings. Both GSTR 2A and 2B are auto-generated statements that show details of purchases and input tax credit (ITC), but they serve different purposes.
Many business owners get confused between these two, leading to filing mistakes or loss of eligible credit. This guide will simplify what GSTR 2A and 2B are, how they are different, and why understanding them is crucial for GST compliance.
What is GSTR 2A?
GSTR 2A is a dynamic, auto-generated statement that gets updated in real time. It contains details of inward supplies (purchases) made by a registered taxpayer from GST-registered vendors.
Key Features:
- Auto-populated from the supplier’s GSTR-1, GSTR-5, and GSTR-6 filings.
- Changes continuously as and when suppliers upload or change invoices.
- Used mainly for reconciliation and cross-verification of ITC claims.
Example:
Let’s say you purchase raw materials from Vendor A on July 5, and they upload their GSTR-1 on July 10. This invoice will appear in your GSTR 2A. If they later correct the invoice on July 25, your GSTR 2A will reflect this updated data.
In simple words, GSTR 2A means a live document that keeps updating.
What is GSTR 2B?
GSTR 2B is a static, auto-drafted statement generated monthly on a fixed date. It shows eligible and ineligible Input Tax Credit (ITC) for a taxpayer based on their suppliers’ filings.
Key Features:
- Generated on the 14th of every month.
- Does not change once generated – it's a snapshot.
- Helps taxpayers finalize ITC for the tax period with certainty.
Example:
Suppose Vendor A files GSTR-1 for June on or before July 13. It will appear in your GSTR 2B for June. But if they file it late on July 20, it will appear in your next month’s GSTR 2B (i.e., for July).
So, GSTR 2B means a fixed document that’s used for actual GST return filing.
Major Difference Between GSTR 2A and 2B
Let’s break it down using simple and easy-to-understand pointers:
Why This Difference Between 2A and 2B Matters
For small business owners, this difference plays a big role in accurate tax filing and avoiding mismatches or penalties.
Key Reasons:
- GSTR 2A helps you track supplier behavior and timely filing.
- GSTR 2B is essential for the final ITC claim while filing GSTR-3B.
- Filing based on GSTR 2A may cause errors as it is not final.
- Using GSTR 2B ensures you claim only valid and eligible ITC.
What is 2A in GST?
If you're wondering, "What is 2A in GST?" it is a report showing auto-drafted purchase data pulled from your vendor’s GSTR-1. It’s a live feed of all the invoices uploaded by your suppliers.
GSTR 2B vs 2A: Real-Life Use Case
Let’s say you are a small garment manufacturer and rely on 10 different fabric suppliers. Some file their GSTR-1 on time; others are late.
- GSTR 2A will show you all invoices, even the ones from late filers, as soon as they upload.
- GSTR 2B, however, will only include invoices uploaded by the 13th of the following month.
So, if you want to know your total purchases for analysis, use 2A. But if you’re filing your monthly return, use 2B.
What If There’s a Mismatch Between GSTR 2A and 2B?
Mismatch between GSTR 2A and 2B is common when:
- Vendors upload invoices late.
- Amendments are made after the 13th of the next month.
- The wrong GSTIN or invoice details are shared.
To fix this:
- Reconcile with vendors.
- Encourage vendors to file GSTR-1 on time.
- Use tools or software that help match invoices automatically.
