Late charges come into play only in case of default.<\/li>\n<li>Professional Charges: Based on the size of the business and the number of invoices generated by it.<\/li>\n<li>Factors Influencing Pricing: Number of filings, complexity of reconciliations, preference for monthly vs. quarterly schemes.<\/li>\n<\/ul>\n<h2>Compliance Requirements After GST Filing<\/h2>\n<ol>\n<li>Keeping the copies of filed returns and tax journals for a period of 72 months is mandatory.<\/li>\n<li>Continuously reconciling GSTR-2B with the internal purchase journal to identify missing invoices.<\/li>\n<li><a href=\"https:\/\/www.kanakkupillai.com\/gst-annual-return-filing\">Annual returns (GSTR-9) and the reconciliation statement (GSTR-9C)<\/a> need to be filed as per the statutory timelines.<\/li>\n<li>Returns can no longer be filed after 3 years. Since 1st July 2025 (per the Finance Act, 2023), GSTR-1, GSTR-3B, GSTR-4, GSTR-9, and other returns cannot be filed on the GST portal once 3 years have passed from their original due date.

Interest is charged at 24% p.a. (instead of the standard 18%) where excess Input Tax Credit is wrongly availed, or output tax is suppressed.<\/li>\n<li>Blocking of E-way Bill: If there are two or more consecutive non-filings of returns, the generation of an e-way bill is stopped.<\/li>\n<li>Risk of Cancellation: Continuous non-filing may lead to cancellation of GSTIN.<\/li>\n<\/ol>\n<h2>Common Mistakes to Avoid while Filing GST<\/h2>\n<ol>\n<li>Errors in documentation: GSTR-1 has errors with HSN codes or GSTIN.<\/li>\n<li>Filing incorrectly: Claiming ITC without reconciling with the data from GSTR-2B generated automatically.<\/li>\n<li>Missing deadlines: Waiting for the last day of filing leads to technical glitches in the GST portal.<\/li>\n<li>Non-compliance and non-usage of post-registration compliance procedures: Not filing Nil returns in case of no transactions.<\/li>\n<\/ol>\n<h2>Benefits of Following GST Calendar<\/h2>\n<ol>\n<li>Practical: Prevents last-minute panic.<\/li>\n<li>Legal: Protects management from notices and recovery actions.<\/li>\n<li>Business credibility: Ensures smooth flow of ITC between businesses.<\/li>\n<li>Growth assistance: Assists in getting working capital loans.<\/li>\n<\/ol>\n<h2>How Kanakkupillai Can Help You with GST Filing?<\/h2>\n<p><strong>1.
