wrong charge gst rate on sale bill

Suggest to issue credit note for differential tax. Give a copy to customer also so that he can ajdust input tax credit also accordinlgy.

I am also agree with Mr. Raja Sir

Credit note not applicable in this case beacuse in this case only Tax Amt reduced Not Taxable Value

Credit Note apply when both Amount change ( Taxable + Tax Amt )

According to me its note be possible to revise that invoice in which charge excess Tax Amt 

In my Opinion that if any option in GSTR-1 than first change only one month.

Its Better to You Filled Return on the basis of Tax which was you have collected

Otherwise you liability arise in this case 

because you have access collected tax Amount and give ITC only Less Amt

Filled GSTR-1 on the basis of 18 % GST rate because you have collceted same amt from customer 

This Medical Oxygen  according to me i things use  by ultimate consumer. So GST Benefit not receive to ultimate consumer.

According to me Its Better to you filled return on the basis of old Tax Rate 

So That This Chapter Close otherwise Liability arise in Future.
