You built your startup to solve a problem, not to drown in paperwork. But here is the reality: investors check your audits before they cut your cheque. Missed filings, unreconciled books, or a poorly handled statutory audit can delay funding rounds, attract regulatory penalties, and — in worst cases — get your directors disqualified.
The good news? Audit compliance is not as overwhelming as it sounds when you know exactly what to do and when. This guide gives you a clear, structured audit checklist for startups in India — covering statutory requirements, tax audit triggers, GST compliance, ROC filings, and the documentation that every investor will ask for during due diligence.
First: Does Your Startup Need a Statutory Audit?
This is where most founders get confused. Let’s settle it clearly.
If your startup is incorporated as a Private Limited Company or a Public Limited Company — statutory audit under the Companies Act, 2013 is mandatory regardless of turnover. Even a company with zero revenue in its first year must get its accounts audited by a Chartered Accountant.
If your startup is structured as an LLP, statutory audit is required only if:
- Annual turnover exceeds ₹40 lakh, OR
- Capital contribution exceeds ₹25 lakh
Tax Audit under Section 44AB (Income Tax Act) applies separately:
- Business turnover exceeds ₹1 crore (₹10 crore if cash transactions are less than 5% of total receipts and payments)
- Professional receipts exceed ₹50 lakh
Understanding which audits apply to your structure is Step Zero. Getting this wrong — either ignoring a mandatory audit or over-complicating your compliance — costs time and money.
The Complete Audit Checklist for Startups
✅ SECTION 1 — Books of Accounts & Basic Financial Records
Before your auditor even begins, your books must be in order. Auditors spend a disproportionate amount of time on startups that hand over messy, unreconciled data. Clean books mean faster audits and lower professional fees.
What to prepare:
- Maintained books of accounts on accrual basis (mandatory under Companies Act)
- Bank statements for all accounts reconciled with books for the full financial year
- Cash book updated — cash transactions below ₹10,000 per day for business expenses
- All sales invoices and purchase bills organized and accessible
- Fixed asset register — with purchase dates, costs, depreciation rates, and WDV
- Loan statements for all borrowings (from directors, shareholders, banks, NBFCs)
- Petty cash records, employee advance registers, and expense vouchers
- Stock/inventory records (if applicable) — opening stock, purchases, closing stock
- List of all related party transactions (founders, directors, group companies)
Pro Tip from ABV & Company: Use cloud-based accounting software (Tally, Zoho Books, or QuickBooks) updated in real time. Startups that maintain monthly-closed books reduce audit turnaround time by over 40% compared to those who compile records only at year-end.
SECTION 2 — Statutory Audit Requirements (Companies Act, 2013)
Every Private Limited Company startup must comply with these audit-linked obligations:
- First Auditor Appointment: Board of directors must appoint the first auditor within 30 days of incorporation. If not done, the shareholders must appoint within 90 days at an EGM.
- Auditor Reappointment: Confirm or reappoint auditor at every Annual General Meeting (AGM). Auditors are appointed for a term of 5 years.
- Audit Completion: Statutory audit must be completed before the AGM.
- AGM Timing: Hold AGM within 6 months of the financial year end — i.e., by 30 September for companies with a March 31 year-end.
- Financial Statements: Prepare balance sheet, profit & loss account, cash flow statement, and notes to accounts as per Schedule III of the Companies Act.
- Board Report: Directors’ report under Section 134 — mandatory and must accompany financial statements filed with MCA.
- Auditor’s Report: Ensure the auditor’s report addresses all CARO 2020 (Companies Auditor’s Report Order) requirements — applicable to most companies.
SECTION 3 — ROC Filings (MCA Compliance)
Post-audit, these MCA filings are mandatory and carry per-day penalties for delays:
| Form | Purpose | Due Date |
|---|---|---|
| AOC-4 | Filing of financial statements with MCA | Within 30 days of AGM |
| MGT-7 / MGT-7A | Annual return (shareholding, directors, etc.) | Within 60 days of AGM |
| DIR-3 KYC | Annual KYC of all directors | On or before 30 September |
| DPT-3 | Disclosure of loans/deposits received | On or before 30 June |
| MSME-1 | Payments delayed >45 days to MSME vendors | Half-yearly |
Warning: Missing DIR-3 KYC deactivates the Director’s DIN. Reactivation costs ₹5,000 as a penalty — avoidable with a single annual filing.
SECTION 4 — Tax Audit Checklist (Section 44AB)
If your startup crosses the turnover threshold, a tax audit is mandatory and must be completed by a Chartered Accountant before filing the ITR.
Documents your CA will need:
- Audited financial statements (P&L, Balance Sheet, Schedules)
- Form 26AS, AIS, and TIS reconciled with books
- TDS deducted and deposited records — all challans and returns (24Q, 26Q)
- Advance tax payment challan copies (if applicable)
- Details of all capital assets sold during the year
- Loans and deposits details (Section 269SS / 269T compliance — no cash loans above ₹20,000)
- MSME payment compliance — dues beyond 45 days disallowed under Section 43B(h)
- Form 3CA/3CB and Form 3CD — completed and filed by the auditor
Key Deadlines:
- Tax Audit Report (Form 3CA/3CB + 3CD): 30 September of the assessment year
- ITR filing (if tax audit applicable): 31 October of the assessment year
- Transfer Pricing (Form 3CEB, if applicable): 30 November
SECTION 5 — GST Compliance Audit
Even if a formal GST audit (GSTR-9C) is not mandatory for your startup, reconciling GST records before your statutory audit is critical. Auditors routinely cross-check GST data with books.
- GSTR-1 and GSTR-3B filed on time for all months of the year
- ITC claimed in books matches GSTR-2B — reconcile mismatches before filing GSTR-9
- GST on RCM (Reverse Charge Mechanism) transactions paid and reported correctly
- E-invoicing compliance — if AATO exceeds ₹10 crore, all B2B invoices reported to IRP within 30 days
- GSTR-9 (Annual Return): Mandatory for all regular taxpayers with turnover above ₹2 crore
- GSTR-9C (Reconciliation Statement + Audit): Mandatory if turnover exceeds ₹5 crore
- GST registration details are updated — address, authorized signatory, bank account
SECTION 6 — TDS Compliance
TDS non-compliance is one of the most common audit flags for startups. Investors and auditors both scrutinize TDS records closely.
- TDS deducted at correct rates on salaries (Section 192), contractor payments (194C), professional fees (194J), rent (194I), and other applicable payments
- TDS deposited by the 7th of the following month (except March — 30 April)
- TDS returns filed quarterly — Form 24Q (salary) and 26Q (non-salary)
- Form 16 issued to all employees by 15 June
- Form 16A issued to vendors/professionals within 15 days of TDS return filing
- TDS on payments to non-residents (Section 195) if applicable — with FEMA compliance
Penalty Note: Late filing of TDS returns attracts a fee of ₹200 per day under Section 234E, plus interest under Section 201(1A). For a startup making significant payments, this adds up fast.
SECTION 7 — Labour & HR Compliance
Often overlooked in audit prep, HR compliance issues surface during investor due diligence and can delay or kill funding rounds.
- Provident Fund (PF): Mandatory if 20 or more employees — monthly contributions and returns
- ESI (Employee State Insurance): Mandatory if 10 or more employees with wages up to ₹21,000/month
- Professional Tax: As applicable in your state — deducted monthly from employee salaries
- Shops & Establishment Registration: Mandatory in most states — verify renewal dates
- Employment agreements signed by all employees with IP assignment clauses
- Offer letters, appointment letters, and increment letters on file
- Gratuity provisions booked in accounts if applicable (5+ years of employee service)
SECTION 8 — Investor & Fundraising Audit Readiness
If you are approaching a Series A round or institutional funding in FY 2026–27, your investor’s due diligence team will ask for every document in this section. Being ready before they ask signals professionalism and accelerates deal closure.
- Audited financials for all years since incorporation — signed, stamped, filed with MCA
- Cap table — fully updated, reflecting all share allotments, ESOPs, transfers, and buy-backs with board resolutions
- ESOP scheme documentation — board approval, shareholder approval, grant letters, vesting schedules
- Shareholder Agreement (SHA) and Articles of Association (AoA) — current, consistent with cap table
- Board and shareholder meeting minutes — all resolutions documented and signed
- FDI compliance (if foreign investment received): FCGPR filing with RBI within 30 days of share allotment to foreign investors
- IP and trademark registrations — ownership assigned to the company (not founders personally)
- Monthly MIS reports — revenue, burn rate, runway, gross margin, key operating metrics
- No outstanding demand notices from IT department, GST authorities, or ROC — or clear documentation of status and next steps
Founder Insight: Investors who do due diligence on a startup with clean, audited books process the round 30–60 days faster than those who discover gaps mid-diligence. One unfiled return or a cap table discrepancy can become a 90-day delay.
SECTION 9 — DPIIT Startup India Recognition (If Applicable)
If your startup holds DPIIT recognition, you are entitled to significant benefits — but also carry specific compliance obligations to maintain that status.
- DPIIT recognition valid and certificate updated
- Section 80-IAC tax exemption applied for (3 consecutive years of income tax exemption available to eligible startups)
- Angel Tax exemption under Section 56(2)(viib) — applicable to DPIIT-recognized startups
- Confirm startup age: DPIIT recognition is valid only for entities up to 10 years from incorporation
- Turnover has not exceeded ₹100 crore in any prior year (eligibility criterion)
Common Audit Red Flags for Startups — What Auditors and Investors Look For
Knowing what raises flags helps you clean up before the audit begins:
Financial red flags:
- Cash receipts or payments above ₹2 lakh (Section 269ST violations)
- Loans received or repaid in cash above ₹20,000
- Related party transactions not at arm’s length or undisclosed
- Personal expenses of founders routed through company books
- Unsupported journal entries or adjustments at year-end
Compliance red flags:
- TDS deducted but not deposited — a criminal liability for directors
- GST ITC claimed on ineligible inputs or without valid tax invoices
- Delayed ROC filings with accumulating per-day penalties
- Directors’ DIN deactivated due to missed KYC
Investor red flags:
- Audited financials not matching MIS data shared during pitching
- Unresolved income tax notices or demands
- ESOP scheme not documented or not approved by shareholders

Why Startups Should Engage a CA Early — Not Just at Audit Time
A common and expensive mistake: treating the statutory audit as an annual event rather than an ongoing process. By the time most startups call a CA, they are dealing with three months of catch-up bookkeeping, missing vouchers, and a filing deadline breathing down their neck.
The startups that scale cleanly — and raise funding faster — are those that work with a CA partner from Day 1. Your auditor is not just signing off on numbers; they are your early-warning system for compliance gaps, your ITC optimization advisor, and your credibility anchor when investors come knocking.
At ABV & Company, we work with startups across India as their year-round compliance partner — from first auditor appointment and books setup to tax audits, ROC filings, and investor due diligence support. We understand that founders need compliance to be seamless, not stressful.
