TL;DR Summary:
Statutory audit in India works best as a year-long process, not a last-minute rush. Close books in April–May, hand records to the auditor by June, use July–September for interim review, complete year-end fieldwork by December, and finish report signing, AGM, and ROC filings by March to avoid penalties and delays.
If you run a company in India, the statutory audit is one of those things that always feels far away – right up until it isn’t. Then suddenly it’s September, your books aren’t closed, the auditor is chasing you, and everyone’s stressed. It doesn’t have to go that way. The whole thing is much calmer when you spread the work across the year instead of cramming it into a few panicked weeks. Below is a simple month-by-month calendar you can actually follow, plus the key dates, a checklist of what to keep ready, and the usual reasons audits drag on (and how to dodge them).
| Quick answer: A statutory audit for a mid-sized Indian company typically takes 8–12 weeks from commencement to signed report. |
Smaller companies with tidy books can wrap up faster. Larger ones, or anyone handing over half-finished records, will take longer. The single biggest thing that decides where you land in that range is how ready your paperwork is on day one. Start clean and the weeks fly by; start messy and the same audit drags into months.
Statutory Audit Timeline: Key Dates at a Glance
Before the month-by-month plan, here are the hard legal deadlines that everything else is built around. These are the dates you genuinely cannot miss without paying for it.
| What you must do | By when | Form / law |
| Appoint your auditor (first one, after incorporation) | Within 30 days of incorporation by the Board | Companies Act, Sec 139 |
| Hold the Annual General Meeting (AGM) | Within 6 months of year-end (by 30 Sept for a March year-end) | Companies Act, Sec 96 |
| Tell the ROC who your auditor is | Within 15 days of the AGM | Form ADT-1 |
| File your audited accounts with the ROC | Within 30 days of the AGM | Form AOC-4, Sec 137 |
| File your annual return | Within 60 days of the AGM | Form MGT-7 |
The catch most people miss: Form AOC-4 is due just 30 days after the AGM. So your audited accounts must already be signed and ready before the meeting, not after. If you hold the AGM on 30 September, your audit needs to be finished well before that. Work backwards from there and the rest of the calendar falls into place.
A Month-by-Month Audit Calendar
Here’s the heart of it. Print this, stick it on the wall, and you’ll rarely be caught out. The dates assume the usual April–March financial year.
| Month | What to do |
| April | Close last year’s books. Start gathering bank statements, invoices, GST and TDS records. |
| May | Finish the trial balance. Clear pending reconciliations — bank, vendor, GST, TDS. |
| June | Hand records to the auditor. Auditor begins planning and sends the document request list. |
| July–August | Interim review and walkthroughs. Auditor raises early queries you can still fix calmly. |
| September | Respond to queries, firm up the draft numbers, and finalise the financial statements. |
| October–November | Main fieldwork: detailed testing, balance confirmations, verifying assets and balances. |
| December | Resolve open points. Review the draft financial statements with the auditor. |
| January | Auditor signs the report. Board approves the accounts. |
| February | Hold the AGM (it must be within six months of year-end — so by 30 September at the latest). |
| March | File AOC-4 within 30 days of the AGM. File MGT-7 within 60 days. |
A quick note on timing: the law lets you hold the AGM as late as 30 September, but the smoothest companies don’t wait that long. They aim to sign the accounts early and hold the AGM well ahead of the deadline, which leaves room for the ROC filings without any last-minute scramble. The calendar above is the relaxed version — adjust the AGM month earlier if your year-end forces it.
The Four Phases of a Statutory Audit
If the month-by-month grid feels too granular, it helps to zoom out and think of the audit year in four simple phases. Same plan, bigger blocks.
Phase 1: Pre-Audit Preparation – April to June
This is where good audits are won. Once the financial year ends on 31 March, your job is to get everything tidy. Close the books, finish your reconciliations, fix any leftover points from last year’s audit, and pull together the records the auditor will ask for. This phase is almost entirely on your finance team, not the auditor. Get it right and the rest is smooth. Skip it and the audit will drag no matter how good your auditor is.
Phase 2: Interim Audit and Walkthroughs – July to September
Now the auditor steps in. They review how your controls work, walk through key processes like sales, purchases and payroll, and test a sample of transactions from the year. The point of doing this mid-year is to catch problems while there’s still time to fix them, rather than discovering them at the very end. This phase is especially useful for larger or more complex businesses, because it spreads the load.
Phase 3: Year-End Fieldwork – October to December
This is the heavy lifting. The auditor digs into the detail — verifying balances, confirming amounts with banks and customers, checking fixed assets, testing year-end adjustments, and reviewing related-party transactions and any legal matters. They’ll raise queries as they go. The faster you answer, the faster this phase ends. Slow, scattered replies are the number one reason fieldwork overruns.
Phase 4: Report Finalization and ROC Filing – January to March
The finish line. Auditor and management agree the final figures, the report is signed and dated, and the board approves the accounts. After the AGM, you file Form AOC-4 with the Registrar of Companies within 30 days, and Form MGT-7 within 60 days. Once those are in, you’re done — and you can breathe until next April.
What to Prepare Before the Auditors Arrive
Most delays come down to one thing: records that aren’t ready. Get these together before the auditor walks in and you’ve already won half the battle.
• Final trial balance, plus the draft balance sheet and profit & loss account
• Bank statements for the full year and the bank reconciliation statements
• Sales and purchase invoices, neatly filed
• GST returns (GSTR-1, GSTR-3B) and the GST reconciliation
• TDS returns and challans
• Fixed asset register with additions and depreciation
• Stock or inventory records and the year-end valuation
• Loan agreements, sanction letters and interest statements
• Board and shareholder resolutions, and the minutes book
• Last year’s signed financial statements and audit report
• Details of related-party transactions
None of this is exotic. It’s the everyday paperwork of running a business. The trick is having it in one place and ready to hand over, not scattered across drives, drawers and three different staff members.
What Causes Audit Delays and How to Prevent Them
An audit that overruns isn’t just stressful — it usually costs more, because the auditor keeps having to come back, and it pushes you towards those ₹100-a-day ROC late fees. Here are the usual culprits and the simple fixes.
| What slows things down | How to prevent it |
| Books not closed when the auditor arrives | Finish year-end closing in April–May, before handover |
| Reconciliations still pending (bank, GST, vendors) | Reconcile every month through the year, not at the end |
| Last year’s audit points never fixed | Clear prior observations early in the new year |
| Slow, scattered replies to auditor queries | Give one person clear ownership of audit responses |
| Missing documents or approvals | Use the checklist above before fieldwork starts |
| New accounting standards or complex deals | Flag them early and discuss treatment with the auditor upfront |
| Leaving everything to the AGM deadline | Aim to sign accounts early and hold the AGM ahead of time |

Why Getting the Timeline Right Actually Matters
It’s tempting to treat the audit as a box-ticking chore you rush through at the end. That’s the expensive way to do it. Miss the filing deadlines and you face penalties under the Companies Act plus ₹100 a day in late fees that never stop on their own. Late audited accounts also hold up your income tax filing, dent the confidence of investors and lenders, and can land you with last-minute audit qualifications because there wasn’t time to fix things properly.
There’s a quieter benefit too. A well-planned audit, done across the year, tends to catch real issues early — a reconciliation that’s off, a provision that’s wrong, a compliance gap you didn’t know about. Fixed in June, those are minor. Discovered in September, they’re a crisis. Treating the audit as a year-long project rather than a year-end event is genuinely the cheaper, calmer choice.
Frequently Asked Questions
When should a statutory audit start?
In practice, the moment the financial year ends on 31 March. Close your books in April and May, then hand records to your auditor by June so the work can begin. Starting early is the single best way to avoid both the stress and the penalties. If you wait until August or September to get going, you’re already on the back foot.
How long does a statutory audit take in India?
For a mid-sized company, expect roughly 8 to 12 weeks from the day the auditor starts to the signed report. Smaller, well-organized companies can be faster. Larger or messier ones take longer. The biggest factor, by far, is how ready your records are when the auditor begins — clean books can cut weeks off the process.
What is the ROC filing deadline for audit reports?
Your audited financial statements go to the Registrar of Companies in Form AOC-4 within 30 days of your Annual General Meeting. The AGM itself must be held within six months of the financial year-end — so by 30 September for a year ending 31 March. The annual return, Form MGT-7, follows within 60 days of the AGM. Miss the AOC-4 date and you pay ₹100 for every day of delay, with no cap on that day-count fee.
Can the audit be done in just a few weeks at the end?
Technically, yes, for a small company with clean books. But it’s risky. Cramming everything into the last few weeks leaves no room for fixing problems, chasing confirmations, or handling auditor queries. That’s exactly when mistakes slip through, and deadlines get missed. Spreading the work across the year is slower on paper but far safer in reality.
