A business that is not registered under GST cannot charge GST.

Every industry in our nation today scrambles to make adaptations to the billing format dictated by the GSTN. This phase of adaptation demands that along with the businesses, even the customers understand the changes that will reflect in the bills they receive. The first piece of information that customers need to keep in mind while they get used to this new regime is that the GST act mandates that only those who are registered with the GST Network and have an assigned GSTIN are eligible to charge the GST rates.

While the customers are catching up to the changes, there are a few restaurants that are taking advantage of lack of knowledge to charge GST rates even though are not registered. Take into consideration a situation that was recently brought to light, where a customer found that a restaurant that wasn’t registered was charging 18% GST. When questioned, they agreed to repay the tax amount but they had been charging all their customers the tax for 10 whole days which is nothing short of a fraud.

As tax paying individuals of the nation, how can you make sure that you are not taken advantage of? Know how to identify a fake GST and then verify its authenticity.

The next 10 digits are the PAN number which has been used to register with the GSTN

The 13th digit indicates the number of registrations that the business has within that state

The 14th digit by default is Z

The 15th digit is a check code used to identify any errors

The state codes assigned by the GSTN are as follows-

01-Jammu and Kashmir

02-Himachal Pradesh

Step 3: Check if you are being charged the right tax percentage on the bill
