OPC annual filing simplified for 2026: AOC-4, MGT-7A, ADT-1, DIR-3 KYC and ITR-6 deadlines, relaxations and penalty risks for One Person Companies.
OPC Annual Filing Made Easy
A One Person Company registered under the Companies Act 2013 must complete three core ROC filings every year — AOC-4 (financial statements), MGT-7A (abridged annual return) and ADT-1 (auditor intimation) — plus DIR-3 KYC, DPT-3 and ITR-6 on the tax side. For FY 2026-27, AOC-4 is due by 27 September 2027 and MGT-7A by 30 May 2027. Missing any deadline attracts Rs. 100 per day per form with no statutory ceiling, and two consecutive years of non-filing can trigger MCA strike-off and a five-year director disqualification — both catastrophic for a structure that has only one person at the helm.
What "Annual Filing" Actually Means for an OPC
Most sole founders who incorporate as an OPC do so to get limited liability and a separate legal identity. What they underestimate is that a company — even with one member and one director — is a statutory entity with its own paper trail. Annual filing is how you prove to the Registrar of Companies (ROC) that the entity is alive, its books are audited, its director is identifiable and its capital structure is accurately reported.
For OPCs, "annual filing" runs across three parallel tracks simultaneously:
- ROC filings — financial statements and annual return with the Ministry of Corporate Affairs (MCA)
- Income tax filings — ITR-6 and, where applicable, a Tax Audit report with the Income Tax Department
- Event-based compliances — auditor intimation (ADT-1), director KYC (DIR-3 KYC), deposit return (DPT-3) and nominee updates (INC-4)
Each track has its own authority, portal, deadline and penalty regime. Build a single master calendar that maps all three — otherwise you will comply with one and inadvertently default on another.
The Three Core ROC Filings: Deadlines, Forms and Fees
AOC-4 — Filing of Financial Statements
What it is: AOC-4 is the form through which a company files its audited financial statements — Balance Sheet, Profit & Loss Account, Board's Report and Auditor's Report — with the ROC on the MCA V3 portal (efiling.mca.gov.in).
OPC-specific note: Unlike private companies, an OPC is not required to include a Cash Flow Statement in its financial statements (Schedule III, Part I exemption). This is a genuine cost-saver if your CA was billing you for preparing one unnecessarily.
Deadline: Within 180 days from the close of the financial year. For FY 2026-27 (year ending 31 March 2027), AOC-4 must be filed by 27 September 2027.
Signatories: The Board's Report must be signed by the sole director. Since the OPC has no company secretary, the director signs the form as well.
Late fee: Rs. 100 per day from the due date until actual filing — with no upper cap under Section 403 of the Companies Act 2013.
MGT-7A — Abridged Annual Return
What it is: MGT-7A is the condensed version of the annual return prescribed for OPCs and small companies. It captures member details, share capital, indebtedness, directors, KMP and remuneration paid.
Why abridged? Full-form MGT-7 (for larger companies) runs to exhaustive disclosures. MGT-7A is significantly shorter and does not require a practising Company Secretary's certification unless the OPC is required to appoint a CS (which is only where paid-up capital exceeds Rs. 5 crore or turnover exceeds Rs. 2 crore — rare at the OPC stage but worth checking).
Deadline: Within 60 days from the date the AGM would have been held. Since OPCs are exempt from holding an AGM under Section 96, the MCA's e-filing system treats the end of the financial year as the reference point. For FY 2026-27, MGT-7A is due by 30 May 2027.
Late fee: Rs. 100 per day from the due date, with no cap.
ADT-1 — Auditor Appointment Intimation
What it is: Every OPC must appoint a Chartered Accountant firm or individual CA as statutory auditor. ADT-1 is the form that informs the ROC of this appointment.
Deadline: Within 15 days of the Board meeting (or resolution) at which the auditor is appointed or reappointed. For a fresh OPC, this is 30 days from incorporation. For ongoing OPCs, it is filed when the existing appointment completes its term or whenever a new auditor is appointed.
Common error: Many OPCs appoint the same CA every year informally and never re-file ADT-1. If the original appointment was for a five-year block (the standard under Section 139(1)), no fresh ADT-1 is needed annually — but if the term has expired and a new block is starting, filing is mandatory.

Print this table, pin it to your compliance folder, and set calendar reminders at the 30-day and 7-day marks before each deadline.
OPC-Specific Relaxations That Actually Matter
OPCs enjoy structural simplifications that reduce governance costs. Know them precisely — some CAs and advisors apply private company rules by default and charge accordingly.
- No AGM required (Section 96 exemption). You save the notice drafting, quorum management and AGM minutes process entirely.
- Minimum two Board meetings per year, with at least a 90-day gap between consecutive meetings. A private company needs four. An OPC with a single director often conducts business by resolution on agenda — ensure these are signed and entered into the minutes book promptly.
- No Cash Flow Statement in financial statements (Schedule III, Part I). This reduces both audit complexity and financial statement preparation time.
- Abridged Board's Report — the detailed disclosures required under Section 134(3) for private companies are not all applicable to OPCs. However, disclosures on related party transactions, director responsibility statement and the auditor's observations must still appear.
- Member's resolution equals general meeting resolution. A written resolution signed by the sole member and entered in the minutes book has the same legal effect as a resolution passed at a general meeting. This means you can approve accounts, change auditors, alter capital and do virtually everything through a written decision — no formality of convening a meeting is needed.
Income Tax Filing: ITR-6, Tax Audit and TDS
ITR-6 and the Due Date
OPCs are taxed as domestic companies under the Income Tax Act 1961. They file ITR-6 (not ITR-5 or ITR-4). For AY 2027-28 (i.e., income earned in FY 2026-27), the due date is 31 October 2027 — provided the OPC's accounts are subject to audit, which is true for virtually every OPC earning any meaningful income.
If ITR-6 is filed late, you lose the ability to carry forward business losses (Section 80 of the Act), which can be extremely damaging for a startup-phase OPC. Interest under Section 234A accrues at 1% per month on the unpaid tax, plus penalty under Section 271F (now replaced by Section 234F — Rs. 5,000 if filed after 31 July, Rs. 10,000 if filed after the original deadline, though for companies the relevant deadline is 31 October).
Tax Audit under Section 44AB
A Tax Audit is mandatory if:
- Turnover exceeds Rs. 1 crore in FY 2026-27; or
- Turnover exceeds Rs. 10 crore where at least 95% of all receipts and payments during the year are in non-cash modes (digital transactions)
The Tax Audit report (Form 3CA-3CD) must be uploaded by the CA before you file ITR-6. Both the audit report and the ITR share the 31 October 2027 deadline for AY 2027-28.
Tax Rates for FY 2026-27
Under Section 115BAA, an OPC (treated as a domestic company) can opt for a flat 22% tax rate, forgoing certain deductions like Chapter VI-A deductions and additional depreciation. Effective rate: 22% + surcharge 10% + health and education cess 4% = 25.168%. Once opted, this election is irrevocable.
For an OPC engaged in manufacturing and set up after 1 October 2019 (subject to eligibility as notified), Section 115BAB offers a 15% concessional rate. Confirm your eligibility with your CA before opting, as conditions on commencement dates apply.
TDS Obligations
OPCs are full-blown deductors. Your TDS calendar for FY 2026-27:
- Salary (Form 24Q): Deduct monthly, deposit by 7th of the following month, quarterly return due 31 July / 31 October / 31 January / 31 May
- Non-salary (Form 26Q — contractor payments, rent, professional fees, etc.): Same deposit cycle; quarterly returns by the same dates
- Late fee under Section 234E: Rs. 200 per day for every day TDS return remains unfiled — on top of interest for late deposit under Section 201(1A)
Even a small OPC paying rent of Rs. 40,000 a month to a corporate landlord must deduct TDS at 10% under Section 194-I and file 26Q quarterly. This is not optional.
Nominee Compliance: INC-3, INC-4 and Why It Cannot Wait
Every OPC must name a nominee — a natural person, resident in India, not a minor — who steps into the membership of the company on the death or incapacity of the sole member. The nominee has zero rights during the member's lifetime; this is purely a continuity mechanism.
At incorporation: The nominee's written consent is captured in Form INC-3, submitted as part of the SPICe+ (INC-32) incorporation bundle.
When the nominee changes: File Form INC-4 with the ROC within 30 days of the change. This is triggered when:
- The existing nominee withdraws consent
- The member nominates a different person
- The nominee dies or becomes incapacitated
The penalty for non-filing is Rs. 100 per day per form. More critically, an OPC without a valid nominee is technically non-compliant with Section 3(1)(c) of the Companies Act, which can attract scrutiny during ROC inspection or while registering any other event-based form.
Voluntary conversion: If your OPC has grown and you want to admit co-founders or investors, convert to a private company through Form INC-6. Since 2021, conversion is purely voluntary — there are no compulsory conversion thresholds based on turnover or paid-up capital.
Step-by-Step: Filing AOC-4 on MCA V3
Here is the exact sequence to file AOC-4 for FY 2026-27 on the MCA V3 portal:
- Prepare documents: Obtain the signed Balance Sheet, P&L, Board's Report, Auditor's Report and, if applicable, consolidated financial statements. Ensure the auditor has digitally signed the audit report.
- Log in: Go to
efiling.mca.gov.in→ Business User login. Use the Director Identification Number (DIN) login or Company login credentials. - Navigate to e-Forms: MCA Services → E-Filing → Company Forms Filing → Financial Statement-related filings.
- Select AOC-4: Enter the Corporate Identification Number (CIN). The system auto-populates company details.
- Fill the form: Select financial year, confirm number of shareholders, attach the financials as a single PDF. The total attachment size limit is 6 MB per attachment. If the financials are larger, compress them or split them across allowable attachment fields.
- Director DSC: The sole director must affix their Class 2 or Class 3 Digital Signature Certificate (DSC). Ensure the DSC is valid and not expired — a common last-minute crisis.
- Pay filing fees: Fees are based on paid-up capital and are paid online through the MCA payment gateway. Keep the Service Request Number (SRN) as proof of filing.
- Download acknowledgment: After successful submission, download the filed challan and SRN confirmation. Store both for at least eight years.
Worked Example: What a Filing Delay Actually Costs
Scenario: Priya runs a consulting OPC with Rs. 18 lakh turnover. She gets occupied with a large client project and files AOC-4 210 days late and MGT-7A 90 days late for FY 2024-25.
AOC-4 late fee: Rs. 100 × 210 days = Rs. 21,000
MGT-7A late fee: Rs. 100 × 90 days = Rs. 9,000
DIR-3 KYC filed 45 days late — flat penalty: Rs. 5,000
Total ROC penalty: Rs. 35,000
Add interest on late ITR-6 at 1% per month on tax due (say, Rs. 80,000 tax outstanding for 3 months): Rs. 2,400
Grand total avoidable outgo: Rs. 37,400 — purely for missing calendar dates on a company with Rs. 18 lakh revenue. That is over 2% of annual turnover burned on penalties for a problem that a one-page calendar prevents.
The same delay in a private company with, say, two directors might look similar in absolute terms — but for an OPC, the sole director's disqualification risk (detailed below) makes the human cost far larger than the financial penalty.
Common Mistakes OPC Directors Make
1. Treating OPC accounts as a formality and auditing them in August. AOC-4 is due in late September. If your CA signs the audit report in late August, you have barely 30 days to review, sign, convert to PDF, test DSC, and file. Any technical glitch on MCA V3 and you have defaulted. Close your books by April, finalise accounts by June, and sign by July.
2. Not filing ADT-1 when the five-year auditor term expires. Section 139(1) limits a statutory auditor's initial appointment to five years. When that block ends and you reappoint the same CA for another five-year term, ADT-1 must be filed within 15 days of the resolution. Many OPCs miss this because "it's the same CA" — the appointment is legally new.
3. Filing ITR-6 without uploading the Tax Audit report first. The Income Tax portal links the Tax Audit SRN to the ITR. If you file ITR-6 before your CA uploads Form 3CA-3CD (or 3CB-3CD), the ITR is defective and you may receive a notice under Section 142(1).
4. Ignoring DPT-3. Every OPC that has any outstanding loans, director loans, security deposits or similar amounts must file DPT-3 by 30 June every year. Directors who lent money to their own OPC often overlook this. Non-filing of DPT-3 attracts Rs. 100 per day — but more seriously, it flags the OPC as potentially accepting deposits in violation of the Companies Act.
5. Using an expired DSC on filing day. DSCs are valid for 2-3 years. Check expiry dates in April every year — don't discover they've expired in September when you're trying to file AOC-4.
Pitfalls to Avoid: Strike-Off and Director Disqualification
Under Section 248 of the Companies Act, the ROC can strike off an OPC if:
- It has not commenced business within one year of incorporation; or
- It has not been carrying on any business for two immediately preceding financial years and has not applied for dormant company status (Section 455)
More immediately relevant: Section 164(2) disqualifies a director if the company in which they are a director has not filed financial statements or annual returns for any three consecutive financial years. The disqualification runs for five years and prevents the person from being appointed as a director of any company during that period.
For an OPC, this is uniquely dangerous. A private company with two directors can still technically function if one is disqualified — the other can sign the belated filings. An OPC with a disqualified sole director has no one authorised to sign anything. You cannot file, you cannot appoint a new director (because no valid director can pass the resolution), and the company effectively becomes inoperable, heading toward strike-off.
How to avoid this entirely: File on time, every time. If you have missed filings, use the MCA's CFSS (Companies Fresh Start Scheme) or LLP Settlement Scheme amnesty windows when notified, or file with additional fees while the company is still in good standing.
Key Takeaways
- Three core ROC filings define OPC annual compliance: AOC-4 (27 Sep 2027 for FY 2026-27), MGT-7A (30 May 2027) and ADT-1 (within 15 days of auditor appointment).
- Late fee is Rs. 100 per day per form with no cap — a 200-day delay across two forms costs Rs. 40,000 before you even open an IT notice.
- OPCs skip the AGM, skip the cash flow statement and skip the full Board's Report — but every other compliance obligation of a domestic company applies fully.
- ITR-6 is due 31 October 2027 for AY 2027-28; missing this date means losing loss carry-forwards and incurring Section 234A interest.
- DPT-3 by 30 June, DIR-3 KYC by 30 September — both are standalone filings that fall outside the main ROC cycle and are frequently overlooked.
- Nominee compliance (INC-4 within 30 days of any change) is not optional — a company without a valid nominee is non-compliant with the foundational OPC eligibility conditions.
- Director disqualification under Section 164(2) for three consecutive years of non-filing is the worst-case outcome and, in an OPC, it is irreversible without judicial intervention — build your compliance calendar in April, not in September.
