The GST Council has introduced a new optional facility, Form GSTR-1A, allowing taxpayers to amend their outward supply or sales return form GSTR-1 before paying taxes for a month or quarter. This amendment can be used to add missing details, correct errors, or make changes to previously declared information. Additionally, taxpayers with an annual turnover of up to Rs 2 crore are exempt from filing annual returns for FY 2023-24.
