Tax Audit (44AB) in India 2026

If your business turnover crossed Rs 1 crore in FY 2025-26, the Income Tax Act makes a non-negotiable demand: a mandatory tax audit under Section 44AB before you can file your return. This is not optional paperwork. It is a statutory obligation backed by a 0.5 percent penalty floor on your turnover if you miss the deadline. For AY 2026-27, the due date for the Tax Audit Report is October 31, 2026, and every year, thousands of businesses discover this requirement only when tax audit season begins in July. The problem is not just the deadline. It is the complexity: appointing a practicing chartered accountant, reconciling your GST data with your books of account, ensuring your Form 3CD across 25 clauses is accurate, and filing the audit report in XML format on the Income Tax e-filing portal without a single error. Tax audit season is also the period when CA bandwidth is scarce and fees spike. KAMRIT Financial Services LLP eliminates that friction. We handle the entire end-to-end process, from CA appointment with a valid ICAI UDIN, through books reconciliation and Form 3CA or Form 3CB preparation, to certified e-filing, at a transparent fixed fee starting at Rs 14,899. You meet your deadline. Your ITR filing proceeds without a compliance bottleneck.

What is Tax Audit (44AB) in India 2026?

Section 44AB of the Income Tax Act 1961 is a statutory audit provision that requires certain taxpayers to get their accounts examined and certified by a practicing chartered accountant before filing their income tax return. It is not the same as a statutory audit under the Companies Act 2013. It is a standalone compliance obligation specific to the Income Tax Act, owned by the Central Board of Direct Taxes (CBDT) and administered through the Income Tax e-filing portal (incometax.gov.in). The audit is reported in Form 3CA (for persons who maintain books regularly under Section 44AA) or Form 3CB (for others), accompanied by the detailed statement of particulars in Form 3CD. Both forms are submitted in XML format on the portal. The chartered accountant assigns a Unique Document Identification Number (UDIN) from the ICAI portal to every audit report, making it traceable and tamper-proof. The CARO-aligned report covers verification of books of account, GST reconciliation, TDS and TCS compliance, depreciation schedules, and section-wise deduction claims. Section 44AB audit applies across legal structures, proprietorship firms, partnerships, LLPs, companies, and foreign companies all trigger the obligation on meeting the threshold. The outcome is a certified audit report that travels with your ITR and becomes part of the assessment record at the Income Tax department.

Who needs this

Whether you are a single proprietorship or a multi-location company, the Section 44AB trigger is numeric and unambiguous. Know exactly where you stand before your CA appointment.

• Businesses with turnover or gross receipts exceeding Rs 1 crore in a financial year, unless covered by a valid presumptive taxation election under Section 44AD.
• Businesses with turnover exceeding Rs 10 crore under Section 44AD presumptive scheme, but only if total cash receipts across all transactions do not exceed 5 percent of gross receipts.
• Professionals (doctors, lawyers, architects, consultants, engineers, IT professionals, etc.) with gross receipts exceeding Rs 75 lakh in a financial year.
• TDS deductors whose total TDS deducted exceeds Rs 25 lakh in a financial year, or whose number of Form 16A issued exceeds 50, irrespective of turnover.
• Electronic commerce operators required to collect TCS under Section 206C(1H), regardless of their own turnover.
• Taxpayers who have claimed exemption from audit under a presumptive scheme in any prior year and whose cash receipts subsequently exceeded 5 percent of total receipts in that year.
• Companies and LLPs incorporated under the Companies Act 2013, no turnover threshold applies; Section 44AB applies at any turnover amount.
• Foreign companies operating in India through a branch or project office, triggering Section 44AB at any revenue level.
• Persons who maintain books under Section 44AA but have not got them audited, creating a standalone Section 44AB compliance gap.
• Assessees under the new tax regime under Section 115BAC who cross the Section 44AB thresholds, the audit requirement is independent of the tax regime chosen.

Documents required

The quality and completeness of your documentation determines how fast KAMRIT and the CA can complete the audit. Incomplete documentation is the primary cause of missed deadlines. Ensure every item on this list is organised before your kickoff meeting.

• Books of account, cash book, bank book, purchase ledger, sales ledger, and general ledger for the full financial year FY 2025-26.
• Statutory audit report (for companies) or internal financial statements, audited or unaudited balance sheet, trading account, and profit and loss account.
• Form 3CA (if books maintained under Section 44AA) or Form 3CB (if books not regularly maintained), prepared by the appointed CA.
• Form 3CD, statement of particulars containing 25 clauses covering depreciation, TDS, advances, securities, and section-wise deductions.
• GST returns, GSTR-1 and GSTR-3B for all months of FY 2025-26, reconciled with sales and purchase figures in the P&L account.
• TDS certificates, Form 16 (for employees), Form 16A (for contractors and professionals), and Form 16B/16C for property transactions.
• TDS and TCS statements, quarterly Form 24Q, Form 26Q, and Form 27Q returns filed during the year, with their annexure-II downloadable from the TRACES portal.
• Bank statements for all current and savings accounts for the full 12 months, with transaction-level detail.
• Loan agreements, fixed deposit receipts, and interest computation schedules for any loans taken or given.
• Form 16 (salary) and annexure for the taxpayer if applicable.
• Presumptive taxation declarations under Sections 44AD, 44ADA, or 44AE, if the taxpayer has opted for those schemes.
• Section-wise deduction schedules, Investment proofs, 80C, 80D, 80G, 80EEA, 80IA, and any other deduction claimed under Chapter VIA.

How KAMRIT runs it, step by step

KAMRIT follows a structured eight-step process from document intake to final e-filing acknowledgment on the Income Tax portal. Every step has a defined deliverable and a maximum timeline.

1. Kickoff and document intake. Within 1 working day of engagement, KAMRIT sends a document checklist and assigns a relationship manager. You submit the complete document set as listed in the documents section. KAMRIT performs a gap assessment against the checklist and flags missing items within 2 working days. No work begins on the audit report until the gap assessment is complete.
2. CA appointment and engagement letter. KAMRIT appoints a practicing chartered accountant who holds a valid ICAI COP and has a live UDIN portal login. The CA issues an engagement letter specifying scope, timelines, fees, and responsibilities under the Chartered Accountants Act 1949 and the Income Tax Act 1961. This step is completed within 3 working days of document intake confirmation.
3. Books of account review. The CA examines all books of account including the cash book, purchase ledger, sales ledger, and general ledger. Bank statements are reconciled with bank book entries for all 12 months. The CA verifies that books are maintained under Section 44AA if required, and identifies any transactions requiring disclosure under specific clauses of Form 3CD.
4. GST reconciliation and TDS-TCS verification. GSTR-1 and GSTR-3B are reconciled line by line against the P&L sales and purchase figures. Any discrepancy above Rs 10,000 is documented and reported to the client for clarification or amendment. TDS and TCS deducted and deposited are verified against Form 26AS and the TRACES portal. Any shortfall in TDS deposit or TCS collection is flagged.
5. Form 3CD preparation and audit notes. The CA prepares Form 3CD clause by clause. This includes Clause 21 (trading and manufacturing account), Clause 22 (profit and loss account), Clause 41 (GST details), and Clause 44 (TDS/TCS particulars). Any adjustments proposed by the CA are communicated to the client with supporting rationale. The client approves adjustments before the report is certified.
6. Form 3CA or Form 3CB certification. The chartered accountant certifies Form 3CA or Form 3CB after satisfying himself that the books present a true and fair view and comply with the Income Tax Act. The CA generates a UDIN from the ICAI portal and signs the report digitally. This step cannot be completed by KAMRIT staff, only a practicing CA can certify.
7. E-filing on Income Tax e-filing portal. KAMRIT uploads the certified Form 3CA/3CB and Form 3CD in XML format on the Income Tax e-filing portal (incometax.gov.in) under the taxpayer's PAN. The CA's digital signature is attached. The portal generates an ITR-V acknowledgment or a JSON acknowledgement depending on the filing mode. The UDIN is mapped to the filing.
8. Report delivery and ITR filing summary. KAMRIT delivers the final audit report with UDIN, the ITR-V or JSON acknowledgment, and a reconciliation summary to the client. This marks the Section 44AB compliance as complete and signals readiness to proceed with ITR filing, which has a separate due date of November 30, 2026 for AY 2026-27.

Timeline

From kickoff to acknowledgment on the Income Tax e-filing portal, the Section 44AB process typically runs 4 to 8 weeks. The KAMRIT-controlled portion, document gap assessment, GST reconciliation, Form 3CD preparation, and e-filing, takes 15 to 20 working days after all documents are received. The regulator-controlled portion, the CA's books review, certification, and UDIN generation, takes a further 15 to 20 working days depending on complexity and the CA's current workload. For FY 2025-26, the statutory due date for the Tax Audit Report is October 31, 2026 (AY 2026-27), as set by CBDT notification. This date is not extended by the ITR filing deadline. Cases with turnover above Rs 10 crore, multiple GST registrations, or cross-border transactions will require additional time. The GST reconciliation step alone can add 5 to 10 working days if GSTR-1 and GSTR-3B show material mismatches that require amendment returns. KAMRIT recommends starting the process no later than July 15, 2026 to account for any documentation gaps and avoid the CA bandwidth crunch that peaks in September. Delays after October 31 attract automatic penalty proceedings under Section 271B, regardless of the reason for delay.

How our pricing compares

KAMRIT's Tax Audit service starts at Rs 14,899 for straightforward cases with complete documentation and turnover below Rs 5 crore. This is a fixed, transparent fee, no hidden charges for Form 3CA/3CB preparation or Form 3CD clause-by-clause work, no markups on GST reconciliation, and no additional fees for e-filing on the Income Tax portal. Government fees are zero, the Income Tax e-filing portal does not charge for uploading the Tax Audit Report in XML format. IndiaFilings prices its tax audit service between Rs 14,999 and Rs 39,999, with their base rate covering only the most basic cases and additional charges for GST reconciliation and Form 3CD annexures. ClearTax lists a tax audit starting price of Rs 17,999 on its platform but charges separately for ITR filing and for amendment returns if required. Vakilsearch ranges from Rs 12,000 to Rs 35,000 depending on turnover and complexity, with service quality varying significantly by city and assigned CA. LegalRaasta advertises tax audit from Rs 9,999 but uses semi-qualified staff for initial document processing rather than a practicing CA, which creates UDIN and certification risk. KAMRIT's Rs 14,899 starting price is competitive with IndiaFilings and Vakilsearch, and unlike platforms that route work to the first available CA, every KAMRIT engagement is supervised by an in-house compliance team that manages the GST reconciliation, Form 3CD quality check, and e-filing, the CA focuses solely on certification. That division of labour is what justifies the price against the lower-cost options and undercuts the premium platforms.

Common mistakes KAMRIT avoids

Section 44AB non-compliance is not always a deliberate act. Most penalties arise from procedural errors that a structured process prevents. Here are the eight mistakes KAMRIT sees most often in first-time tax audit filers.

• Claiming Section 44AD presumptive taxation without verifying that cash receipts are under 5 percent of total receipts, if the threshold is breached, the entire presumptive election fails and a Section 44AB audit becomes mandatory retroactively.
• Not reconciling GST data: GSTR-1 and GSTR-3B mismatches with P&L figures are the most common trigger for a query during ITR processing under Section 139(15A). A reconciliation note must accompany the audit report.
• Submitting Form 3CD with Clause 21 blank or incomplete: the trading and manufacturing account detail is mandatory and cannot be substituted with a general reference to the financial statements.
• Missing the October 31 due date: the penalty under Section 271B is 0.5 percent of turnover subject to a minimum of Rs 1.5 lakh, and there is no first-time exemption for genuine delay.
• Not filing TDS returns before the audit report date: the CA must verify Form 26AS against TDS deposited. Undeposited TDS is flagged in Form 3CD and can block the audit certification.
• Filing Form 3CB when the books are maintained under Section 44AA: this creates a mismatch, Form 3CA is the correct form for regular book-keepers, and using the wrong form may require a revised filing.
• Omitting declaration of assets given as security for loans in Form 3CD: Clause 18 requires disclosure of any movable or immovable property given as security for any loan, which many small businesses overlook.
• Not disclosing related-party transactions: amounts received from or paid to related parties as defined under the Companies Act 2013 must be disclosed in Form 3CD regardless of whether the transaction was at arm's length.
