Understanding taxes can be tricky. But don’t worry! This guide will explain how to find GST on purchases in a way that’s easy to follow. Whether you’re a student, small business owner, or just curious, you’ll learn how GST works, how to calculate it, and why it’s important.
Let’s start from the basics and move step by step. By the end, you will feel confident about checking GST on purchases anytime.
What is GST and Why It Matters?
Before learning how to find GST on purchases, you need to know what GST is. GST stands for Goods and Services Tax. It’s a tax you pay when you buy products or services.
The government collects this tax. It helps fund public services like schools, hospitals, and roads. Different products and services have different GST rates. Some items may even be tax-free.
When you buy something, the bill will often show the price before tax and the GST amount separately. But sometimes it’s not that clear. That’s why knowing how to find GST on purchases helps you check if you’re paying the right amount.
Where Does GST Show Up on a Bill?
Most invoices or receipts show GST clearly. It’s usually labeled as “GST,” “CGST,” “SGST,” or “IGST.”
CGST is the Central GST.
SGST is the State GST.
IGST is the Integrated GST, applied when buying from another state.
For example, if you buy goods worth ₹1000 with 18% GST, the bill might look like this:
Item price: ₹1000
CGST @ 9%: ₹90
SGST @ 9%: ₹90
Total: ₹1180
This way, you know exactly how much tax is being charged.
However, some receipts may not show details. In that case, you can still calculate GST. Let’s learn how.
How to Find GST on Purchases Manually
It’s easier than you think! Follow these steps to find GST on any purchase.
Step 1 – Know the GST Rate
Check the GST rate that applies to the product or service. Common rates are:
5%
12%
18%
28%
For example, most electronics have 18% GST.
Step 2 – Find the Total Amount Paid
Look at your bill and see the total amount you paid. Let’s say it’s ₹1180.
Step 3 – Use the Formula
If the total includes GST, you can calculate the tax using this formula:
GST Amount = Total Amount × GST Rate / (100 + GST Rate)
Let’s calculate for ₹1180 with 18% GST:
GST Amount = 1180 × 18 / (100 + 18)
GST Amount = 1180 × 18 / 118
GST Amount = 21240 / 118
GST Amount = ₹180
So, ₹180 is the GST included in your total.
Another Way: Calculate GST From Taxable Amount- find GST on purchases
If your bill shows the price before tax, just multiply the amount by the GST rate.
GST Amount = Taxable Amount × GST Rate / 100
For example, taxable amount = ₹1000, GST rate = 18%:
GST Amount = 1000 × 18 / 100 = ₹180
Add the GST to the taxable amount:
Total = 1000 + 180 = ₹1180
