Tax Audit (Sec 44AB) — Form 3CA/3CB & 3CD: Where It Goes Wrong
The failures on Tax Audit (Sec 44AB) — Form 3CA/3CB & 3CD repeat, which means they are avoidable if you know what to watch. The questions below are the ones raised most often in practice; the full scope of the service is on the Tax Audit (Sec 44AB) — Form 3CA/3CB & 3CD page.
What is the risk of using an online portal or a low-cost preparer for my tax audit instead of a CA firm?
A tax audit report is a professional certification, not a data-entry form — it requires independent verification of GST turnover reconciliation, TDS compliance, statutory dues payment timing, and cash transaction compliance, each of which requires judgment and access to source documents, not just software that populates Form 3CD fields from whatever numbers are typed in. A report signed without genuine verification exposes you, not the preparer, to the consequences if the Department later finds a discrepancy — the CA's signature does not protect you from your own underlying non-compliance if it was never actually checked.
In practice: A Form 3CD showing 'Nil' against every disallowance clause is a warning sign where the books contain clear TDS defaults or cash transaction violations. A tax audit that finds nothing wrong in a business with real compliance gaps was not actually verifying anything.
What if the tax audit uncovers an error or discrepancy in my books?
We flag it to you directly and work through the correction before the report is finalised — correcting entries in the books where appropriate, obtaining missing documentation, or, where a genuine disallowance applies (for example, a TDS default that cannot be cured before the return due date), reporting it accurately in Form 3CD rather than concealing it. An accurate report that discloses a disallowance is far less risky than an inaccurate report that omits one and is later discovered on scrutiny.
In practice: Clients sometimes ask whether an issue can simply be left out of the report. Our answer is consistently no — a tax auditor who knowingly certifies an inaccurate Form 3CD exposes both the client and the auditor to professional and legal consequences that far outweigh the disallowance itself.
Can the same CA firm conduct my tax audit every year, or is rotation required?
Unlike the Companies Act statutory audit, which mandates auditor rotation for certain classes of companies under Section 139(2), the Income-tax Act does not impose a mandatory rotation requirement for tax auditors under Section 44AB. You are free to continue engaging the same CA firm for your tax audit year after year, which in practice allows the auditor to build institutional knowledge of your business, recurring risk areas, and prior-year positions — often producing a more efficient and higher-quality audit over time.
In practice: We find continuity genuinely valuable for tax audits specifically — a firm that has audited your books for several years catches subtle year-on-year anomalies (a sudden change in a ratio, an unusual related-party transaction) that a first-year auditor starting from zero context would likely miss.
How does PNPC's tax audit process differ from a generic accounting firm or online filing service?
A generic service often treats Form 3CD as a template to be populated from whatever figures the client's bookkeeping software produces, with limited independent verification. PNPC's process specifically includes GST-turnover-to-books reconciliation, TDS deduction-and-deposit verification against Form 26AS and TDS returns, Section 43B statutory dues payment-date testing, and Section 269SS/269T cash transaction review — the exact areas the Department's automated scrutiny-selection system focuses on. We treat the audit as risk-reduction for you, not a filing formality for us.
In practice: We have taken over tax audit engagements from clients whose prior auditor never once asked to see GST returns or TDS challans — the audit report was signed purely from the trial balance. That is not a tax audit in any meaningful sense, even if the form was technically filed.
Does PNPC also prepare and file my income tax return, or only the tax audit report?
PNPC typically handles both as a coordinated engagement — the tax audit (Form 3CA/3CB and 3CD) and the ITR itself (ITR-3 for individuals/HUFs with business/professional income, ITR-5 for firms/LLPs, or ITR-6 for companies) — precisely because the two documents must be internally consistent. Preparing them separately, or through different providers, increases the risk that the return contradicts the audit report.
In practice: We have corrected returns prepared by a different provider that reported turnover or disallowance figures inconsistent with an already-filed Form 3CD from a separate tax auditor. Coordinating both under one engagement removes this risk entirely.
Is a tax audit required for a business operating entirely through e-commerce or online marketplaces?
Yes, on the same turnover-based principles as any other business — an e-commerce seller's turnover for Section 44AB purposes includes the gross value of goods/services sold through the marketplace, not merely the net commission or margin retained. E-commerce sellers should also specifically verify TDS deducted by the marketplace operator under Section 194-O (TDS on e-commerce transactions) is correctly reflected and reconciled against their Form 26AS, as this is a common area of mismatch in Form 3CD's TDS disclosures.
In practice: 'Turnover' for GST purposes (often net of platform fees in a seller's own accounting) is easily confused with 'turnover' for the Section 44AB threshold test, which is based on gross sales value. We clarify and reconcile this distinction as one of the first steps in any e-commerce client's tax audit.
