Frequency: GST annual return must be filed by all regular GST taxpayers on an annual basis. The financial year in India typically runs from April 1st to March 31st.

Forms: There are different forms for different types of taxpayers. The primary forms for GST annual return filing in India are GSTR-9, GSTR-9A, and GSTR-9C.

• GSTR-9: This is the regular annual return form for most taxpayers. It includes details of all outward and inward supplies made during the year.

• GSTR-9A: This form is for composition scheme taxpayers.

• GSTR-9C: This is a reconciliation statement and certification form that is filed along with GSTR-9 by taxpayers with a turnover exceeding a specified limit. It requires certification by a Chartered Accountant or a Cost Accountant.

Information Included: The GST annual return typically includes information on the taxpayer's turnover, tax paid, input tax credit availed and reversed, and details of outward and inward supplies. It helps in reconciling the data reported in GST returns throughout the year.

Deadline: The due date for filing the GST annual return is usually December 31st of the subsequent financial year. However, this date can be extended by the government.

Late Fees: If a taxpayer does not file the annual return by the due date, they may be subject to late fees and penalties.

Reconciliation: The annual return is an important tool for taxpayers to reconcile their data with that of the government. It helps in identifying discrepancies and rectifying them.

Audit: For taxpayers with a turnover above a specified threshold, the GST annual return must be audited, and the audit report (GSTR-9C) must be filed along with the return.

Adjustments: Taxpayers can make adjustments for any differences or errors identified during the annual return filing. This ensures that the GST liability is correctly calculated.
