First, Is It GSTAT or GSTR?
Let's clarify a common point of confusion. The headline mentions 'GSTAT', which stands for the Goods and Services Tax Appellate Tribunal, a body for resolving GST-related disputes. However, the process of filing tax returns falls under 'GSTR', which stands for Goods and Services Tax Return.
For most businesses, GSTR is the term you'll interact with regularly. This guide focuses on demystifying the GSTR filing process.
The Two Most Important Returns: GSTR-1 and GSTR-3B
Think of GST filings as a two-part story you tell the government each month or quarter. The first part is GSTR-1. This is where you declare all your sales, or 'outward supplies'. It's a detailed report, listing invoices so your buyers can claim their tax credits. The second part is GSTR-3B. This is a summary of your sales, purchases, and final tax liability after claiming your own credits (Input Tax Credit or ITC). This is the return you file when you actually pay the tax you owe. Filing both accurately and on time is the foundation of GST compliance.
Decoding the Monthly Filing Window
For businesses with an annual turnover exceeding ₹5 crore, the rhythm is monthly and predictable. GSTR-1, the sales declaration, is due by the 11th of the following month. So, for sales made in July, you file GSTR-1 by August 11th. GSTR-3B, the summary and payment return, is due by the 20th of the following month. So, for July, the tax is due by August 20th. It's a simple sequence: declare your sales by the 11th, then pay the net tax by the 20th. Following this timeline ensures your buyers can claim their credits promptly and you remain compliant.
A Simpler Path: The QRMP Scheme
For small and medium-sized businesses with an annual turnover of up to ₹5 crore, the government created the QRMP (Quarterly Return Monthly Payment) scheme. This is a significant relief, allowing you to file both GSTR-1 and GSTR-3B once every quarter instead of every month. However, tax payments are still made monthly. By the 25th of each of the first two months of a quarter, you pay your estimated tax liability using a simple challan, Form PMT-06. In the third month, you file your quarterly returns and settle the final tax amount. The GSTR-1 is due by the 13th of the month after the quarter ends, and GSTR-3B is due by the 22nd or 24th, depending on your state.
The Cost of Missing the Window
The GST portal is strict about deadlines, and delays come with consequences. For late filing of GSTR-1 and GSTR-3B, a standard late fee of ₹50 per day (₹25 for CGST and ₹25 for SGST) applies. For nil returns (where you have no transactions to report), the fee is lower at ₹20 per day. In addition to the fixed late fee, you are also liable to pay interest at a rate of 18% per annum on the amount of tax that was due. These charges can accumulate quickly, turning a small oversight into a significant financial burden. Consistently missing deadlines can also lead to other restrictions, such as the inability to generate e-way bills.
Your Simple Filing Checklist
To stay on track, follow these simple steps. First, close your books promptly at the end of each month. Second, reconcile your sales data carefully before preparing your GSTR-1. Third, use the time between filing GSTR-1 and GSTR-3B to confirm your Input Tax Credit eligibility based on your GSTR-2B (an auto-populated statement of your purchases). For QRMP filers, remember to make your monthly tax payments by the 25th. Set calendar reminders for the key dates: the 11th, 13th, 20th, 22nd/24th, and 25th, depending on your filing frequency. This routine will help make GST compliance a seamless part of your business operations.
