Registering your business is just the beginning. Whether you complete company registration in Kolkata or company registration in Noida , your responsibilities as a business owner start immediately after you receive your Certificate of Incorporation.
This article outlines the essential steps and legal compliances every startup or private limited company must follow post-registration in 2025.
✅ Step 1: Apply for PAN & TAN
Once you complete the incorporation process, your company will automatically be issued a Permanent Account Number (PAN) and Tax Deduction and Collection Account Number (TAN) by the Income Tax Department.
- Why it matters: PAN is required for all financial transactions, and TAN is mandatory if you deduct TDS (Tax Deducted at Source) while paying employees, freelancers, or vendors.
🏢 Step 2: Open a Business Bank Account
A corporate current account is mandatory for any registered business. After company registration in Kolkata or company registration in Noida, use your incorporation documents and PAN to open a business bank account.
- Tip: Choose a bank offering digital banking, bulk payments, and integration with accounting software for ease.
📜 Step 3: Register for GST (If Applicable)
If your turnover exceeds ₹40 lakhs (₹20 lakhs for services), or if you're operating across states, you must register for Goods and Services Tax (GST).
- For tech startups in Noida, early GST registration is often required due to B2B billing.
- Businesses in Kolkata, especially those in manufacturing or logistics, also benefit from early GST compliance.
🗂️ Step 4: Maintain Statutory Registers and Records
After registration, your company is legally required to maintain:
- Register Members
- Register of Directors & Shareholdings
- Minutes of Board Meetings
- Statutory Audit Reports (annually)
This applies to companies in both Noida and Kolkata, under the Companies Act, 2013.
🧾 Step 5: File ROC Returns Annually
Every company registered in India must file annual returns with the Registrar of Companies (RoC), regardless of whether they've begun operations or made profits.
- RoC Kolkata and RoC Noida both enforce strict penalties for delayed filings.
- Use professional help to file MGT-7, AOC-4, and DIR-3 KYC on time.
👥 Step 6: Appoint an Auditor
All companies must appoint a Chartered Accountant (CA) as statutory auditor within 30 days of incorporation.
- In Noida, where startups often raise funds, audit readiness is crucial.
- In Kolkata, SMEs and traditional businesses also require proper auditing to avoid legal risks.
📢 Bonus: Start Your Branding Legally
Now that you've completed company registration in Kolkata or company registration in Noida, don't forget to:
- Register your brand name/trademark
- Create a professional website with your company name and CIN
- List your company on GST and MCA portals for verification
🔚 Final Thoughts
Getting your company registered in Kolkata or company registered in Noida is a great first step in 2025. But remaining compliant and legally sound is key to long-term success. Following this checklist ensures you avoid penalties, stay investor-ready, and build a trustworthy brand from day one.
