What to Do After GST Registration: Next Steps and Compliance

Once you receive your GST registration certificate (Form GST REG-06), you must verify the details and take several immediate actions. First, check that your business name, address, PAN, and constitution type are correct. If any details are wrong, you must file an application for amendment in Form GST REG-14 within 15 days of registration.

Next, you must display your GST registration certificate prominently at your principal place of business. You also need to print your GSTIN (Goods and Services Tax Identification Number) on all tax invoices, bills of supply, and other documents. Additionally, you should update your business stationery, website, and any public-facing materials with your GSTIN. Under Section 31 of the CGST Act, 2017, every registered person must issue a tax invoice for every supply of goods or services.

You must start issuing GST-compliant invoices immediately after registration. A valid tax invoice must include your name, address, GSTIN, invoice number, date, buyer's details (if registered, their GSTIN), HSN/SAC code, description of goods/services, quantity, taxable value, rate of tax, and the amount of CGST, SGST/UTGST, or IGST. The invoice number must be unique for each financial year.

You should also set up your accounting software to generate GST-compliant invoices and maintain proper records. The GST law requires you to keep accounts of all supplies, purchases, output tax, input tax credit, and stock for at least 72 months from the due date of filing the annual return. Many businesses use GST-compliant accounting software or hire a tax professional to ensure accuracy. If you are a composition dealer, you must issue a bill of supply instead of a tax invoice, as you cannot charge GST to customers.

After registration, you must file GST returns regularly based on your chosen scheme. The most common return is GSTR-3B, a monthly summary return due by the 20th of the following month. You must also file GSTR-1 (details of outward supplies) monthly or quarterly, depending on your turnover. For businesses with annual turnover up to ₹5 crore, you can opt for the quarterly filing of GSTR-1.

Additionally, you must file an annual return in Form GSTR-9 by 31st December of the following financial year. If you are a composition dealer, you file GSTR-4 annually. Late filing attracts a late fee of ₹50 per day (₹25 each for CGST and SGST) and interest at 18% per annum on the tax amount. You must also reconcile your purchase data with your suppliers' GSTR-2A/2B to claim input tax credit correctly. Missing returns can lead to suspension of registration.

Input Tax Credit (ITC) allows you to reduce the tax you pay on your supplies by the tax you paid on your purchases. To claim ITC, you must have a valid tax invoice from a registered supplier, and the goods/services must have been received. You can claim ITC only if your supplier has filed their GSTR-1 and the invoice appears in your GSTR-2A/2B.

You must also ensure that the supplier has paid the tax to the government. Under Section 16 of the CGST Act, ITC is available only if the tax charged on the supply has been actually paid to the government. You cannot claim ITC on goods or services used for personal consumption or for making exempt supplies. You must reverse ITC if you fail to pay the supplier within 180 days of the invoice date. Proper ITC management is critical to avoid notices and demands from the tax department.

Beyond returns and invoicing, you must comply with several other requirements. You must file an annual self-certified reconciliation statement in GSTR-9C if your turnover exceeds ₹5 crore. You must also maintain a digital record of all e-way bills if you transport goods worth more than ₹50,000. The e-way bill system is mandatory for inter-state movement and intra-state movement in many states.

You must also update your GST registration details within 15 days of any change in business name, address, partners, or constitution. If you close your business, you must apply for cancellation of registration in Form GST REG-16. Non-compliance can result in penalties, interest, and even suspension or cancellation of your GST registration. You should also keep track of changes in GST rates, rules, and notifications issued by the GST Council.

If you are unsure about any compliance step, consult a qualified chartered accountant or GST practitioner. They can help you set up your accounting system, file returns correctly, and avoid penalties. For your specific business situation, professional advice is essential.
