GST Returns: Common Forms and Filing Timelines

Businesses registered under GST are required to file periodic returns summarising their sales, purchases, tax collected, and tax paid. The returns that apply depend on the type of registration and the turnover of the business.

Commonly filed returns: GSTR-1 captures details of outward supplies (sales). GSTR-3B is a summary return through which tax is paid. GSTR-9 is an annual return applicable to certain taxpayers. Businesses registered under the Composition Scheme file returns suited to that scheme.

Filing frequency: Returns may be filed monthly or quarterly, depending on the option chosen and the turnover of the business. Quarterly filing is available to eligible smaller taxpayers under the applicable scheme, often together with a monthly payment of tax.

Why timely filing matters: Late filing can attract late fees and interest, and can affect the ability of recipients to claim input tax credit. Consistent, timely filing also keeps a business's compliance record in good standing.
