Why Knowing GST On Domestic Purchases Matters
Before diving into numbers, let’s understand why it matters.
When you buy goods or services within India, GST is charged by the supplier. This is called input tax. Tracking this GST is important because:
You can claim input tax credit (ITC).
It helps in accurate tax filing.
It ensures you pay only the correct amount of GST.
It gives a clear view of expenses.
Simply put, knowing the GST on domestic purchases saves money and avoids penalties.
Step 1: Collect All Purchase Invoices
The first step in finding GST on domestic purchases is to gather your invoices.
Invoices are proof of your purchase. Every invoice should show:
Supplier name and GSTIN
Invoice number and date
Description of goods or services
Total value of purchase
GST charged (CGST, SGST, or IGST)
Tip: Keep invoices organized by date or supplier. This makes checking GST much easier.
Step 2: Identify The GST Charged
Once invoices are collected, you need to check the GST charged.
For intra-state purchases (same state), the invoice shows CGST + SGST.
For inter-state purchases (different states), it shows IGST.
Look carefully at the invoice. Sometimes GST is included in the price, and sometimes it is extra. Make sure you separate the GST amount from the total value.
Step 3: Use GSTR-2B To Check Domestic Purchases
The GST portal offers a helpful report called GSTR-2B.
GSTR-2B is an auto-drafted statement of all inward supplies (purchases) for a tax period.
It shows all domestic purchases, including tax details.
You can use it to cross-check your invoices and ensure no GST is missing.
How to use it:
Log in to GST Portal.
Navigate to Services → Returns → GSTR-2B.
Select the financial period.
Download the report in Excel or PDF.
Check the column for GST charged on each purchase.
This makes finding GST on domestic purchases much faster.
Step 4: Categorize GST By Type
It helps to categorize GST for better understanding.
CGST: Central Goods and Services Tax.
SGST: State Goods and Services Tax.
IGST: Integrated Goods and Services Tax for inter-state purchases.
If your purchase is within the same state, the invoice usually shows CGST + SGST. If it’s from another state, it shows IGST.
Categorizing GST ensures correct input tax credit calculation.
Step 5: Check For Input Tax Credit Eligibility
Not all GST on domestic purchases is eligible for credit. You can claim ITC only if:
You have a valid GST invoice.
Goods/services are used for business purposes.
GST is correctly charged by the supplier.
Purchases are recorded in GSTR-2B.
Always reconcile invoices with GSTR-2B. This reduces errors and ensures you claim all eligible GST.
Step 6: Calculate GST On Domestic Purchases
Calculating GST is simple once you have invoices and GSTR-2B data.
Formula:
For intra-state:
GST = CGST + SGSTFor inter-state:
GST = IGST
Add up GST amounts from all invoices or GSTR-2B report for the chosen period. This gives you total GST paid on domestic purchases.
Tip: Use Excel or accounting software for easier calculation and reconciliation.
Step 7: Reconcile GST With Accounting Records
After calculation, always reconcile GST with your accounting books.
Compare invoice GST with purchase ledger.
Match totals with GSTR-2B report.
Check for missing invoices or wrong GST amounts.
Reconciliation ensures:
Accuracy in tax filing
No missed ITC claims
Avoidance of penalties
Step 8: Use GST Reports For Better Insights
Finding GST on domestic purchases is not just about tax filing. It also gives business insights:
Identify suppliers charging correct GST
