September is usually fantasized as the month of transition — an indicator that the year is progressing toward its last quarter. But for Chartered Accountants, tax advisers, and companies, September is anything but tranquil. It’s the most hectic and stressful month of the financial calendar.
At Ruchita Dang Associations, a well-known Company Registrations Consultant, we assist clients in remaining compliant and worry-free throughout the year. But wait until September, and even the most planned companies start sweating. Why? Because six key deadlines overlap in this month, under Income Tax, ROC filings, GST audits, and others.
Whether you are a startup, private limited company, LLP, or a sole proprietor — September is the month you cannot afford to mismanage.
1. 15th September: Advance Tax (2nd Installment)
Second installment of Advance Tax for the financial year is payable on 15th September. It is for:
- Individuals with substantial income apart from salary (freelancers, consultants, etc.)
- Companies and LLPs under regular or presumptive tax regime
- Professionals under Section 44ADA
Why it matters
If your total tax liability for a year is more than ₹10,000, you are obligated to pay tax in quarterly advance installments. Failure to meet the deadline results in:
- 1% per month interest as per Section 234B and 234C
- Scrutiny notices and fines
We, as a Company Registrations Consultant, compute, estimate, and deposit Advance Tax on behalf of our clients based on the latest income estimates, thereby helping them not overpay or underpay.
2. 15th September: LLPs Non-Audit Income Tax Return Filing
15th September is an important date for non-audit LLPs, HUFs, and individuals. If your company is not subject to a tax audit, you need to file your ITR by 15th September. These include:
- LLPs with below the audit limit turnover
- Consultants or freelancers under the presumptive scheme
- Small proprietorships or e-commerce sellers
- Consequences of non-compliance:
- ₹5,000 late charges under Section 234F
- Ineligibility to carry forward business losses
- Loss of TDS refunds or Input Tax Credits
As a complete-service Company Registrations Consultant, we ensure your ITRs are filed with proper business codes, bank verifications, and associated GSTR-3B data for hassle-free scrutiny.
3. 30th September: DIN KYC / DIR-3 KYC Filing
Each Indian company director has to annually renew their KYC by way of DIR-3 KYC or DIR-3 KYC Web form. This is a requirement under MCA regulations.
Penalties for late compliance:
- DIN gets deactivated
- ₹5,000 per director penalty
- Cannot file any ROC form (such as AOC-4, MGT-7, etc.)
At Ruchita Dang Associations, we actively deal with all directors’ KYC responsibilities for you, keeping your MCA filings clean and uninterrupted. We also serve as a Company Registrations Consultant for DIN allotments and changes.
4. 30th September: Finalization of Books & Coordination of Statutory Audit
This is the month of preparation for those companies which are mandated to be audited under the Companies Act or Income Tax Act. It is the time when you must:
- Finalize books of accounts
- Close TDS ledgers and reconcile Form 26AS
- Prepare depreciation schedules and trial balances
- Commence coordination with statutory auditors
A Company Registrations Consultant such as us ensures your accountants and auditors are well coordinated, facilitating the completion of internal records and avoiding audit delays.
5. 30th September: Annual General Meeting (AGM) for Companies
As per Section 96 of the Companies Act, AGMs should be held within 6 months from end of financial year, i.e., by 30th September (in non-extended cases). The following are discussed in this meeting:
- Financial statements (AOC-4)
- Director reports
- Appointments of auditors (ADT-1)
- Declaration of dividends (if any)
If AGM is postponed or omitted:
- ₹1 lakh penalty on company + ₹5,000 for each day of default
- Legal repercussions under Section 99
As a reliable Company Registrations Consultant, we prepare notices, resolutions, minutes, and even facilitate virtual AGMs on MCA-approved forms.
6. September: Begin GST Audit Preparation for GSTR-9 & 9C
Although GSTR-9 and 9C are due by 30th November, preparation begins in September for all firms reaching the ₹5 crore mark.
GST audit is not merely filing; it includes:
- Matching outward supplies with GSTR-1 and 3B
- Verification of Input Tax Credit availed
- Preparation of reconciliation and audit reports
- Obtaining GSTR-9C certification by a CA
We work with businesses as their Company Registrations Consultant by taking care of:

Pro Tip from a Company Registrations Expert
