GSTR-3B is a monthly or quarterly summary return that registered taxpayers must file under the Goods and Services Tax (GST) regime. It contains details of outward supplies, inward supplies liable to reverse charge, Input Tax Credit (ITC) claimed, and tax payments made during the tax period.
Errors in GSTR-3B can lead to notices, interest liabilities, ITC mismatches, and compliance issues. Understanding the common mistakes made while filing GSTR-3B can help businesses ensure accurate GST compliance.
