Tax Due Diligence & Special Assignments: What It Actually Involves
Every acquisition, investment, restructuring, or lending decision carries hidden tax exposure that a balance sheet alone will never reveal — an unresolved reassessment, a disallowed expense buried in three-year-old returns, a TDS default that becomes the buyer's problem the day the deal closes. PNPC Global conducts tax due diligence and special assignments for acquirers, investors, lenders, and boards across India and the UAE — reading behind the filed return to the exposure that actually travels with the transaction. We have done this since 1986.
Understanding the Service
Tax due diligence is a focused financial and legal review of a target entity's direct tax and indirect tax position — undertaken ahead of a merger, acquisition, investment round, internal restructuring, loan sanction, or any transaction where a buyer, investor, or lender needs to understand the tax exposure they are about to inherit. Unlike a statutory audit, which expresses an opinion on whether financial statements present a true and fair view for a given year, tax due diligence looks specifically at exposure — open assessments, pending appeals before CIT(A) or ITAT, TDS defaults under Chapter XVII-B, transfer pricing risk under Section 92C for related-party transactions, carry-forward loss eligibility under Sections 79 and 72A on a change of control, GST exposure under the CGST Act, and the tax cost of the deal structure itself — whether it is a share purchase, slump sale under Section 50B, business transfer, or scheme of arrangement under Sections 230-232 of the Companies Act. Note on section references: the Income-tax Act, 1961 was repealed and replaced by the Income-tax Act, 2025 with effect from 1 April 2026, which renumbers most sections (for example, the erstwhile Sections 147-151 on reassessment now correspond to Sections 279-284) while broadly preserving the underlying rules.

When You'd Need This
- You are acquiring shares or a controlling stake in an Indian or UAE entity — historical tax liabilities transfer with the shares in a share purchase, unlike an asset purchase
- You are a PE or VC fund conducting pre-investment diligence before a term sheet is finalised or before the definitive round closes
- You are planning a merger, demerger, or scheme of arrangement and need to confirm the scheme qualifies as tax-neutral under Sections 47(vib)/47(vid) and 2(19AA) before filing with the NCLT
- A lender or bank requires an independent tax health-check as a condition precedent before sanctioning a credit facility or term loan
What This Doesn't Cover
- You need only the annual statutory tax audit under Section 44AB — that is a distinct, recurring compliance engagement, not a transaction-driven review
- You are simply seeking representation on an existing income tax notice or scrutiny assessment with no transaction in the background — that is faceless assessment and appellate representation, not due diligence
- You need routine TDS or GST compliance management with no acquisition, investment, or restructuring event — that is ongoing compliance retainer work
Quick Answers
What exactly is tax due diligence, and how is it different from a statutory audit?
A statutory audit under Section 143 of the Companies Act (or a tax audit under Section 44AB of the Income-tax Act) expresses an opinion on whether financial statements present a true and fair view, or whether the tax computation for a given year is correctly stated, for that specific reporting period. Tax due diligence is transaction-driven — it looks across multiple years at open assessments, pending litigation, TDS defaults, transfer pricing exposure, and the tax cost of the deal structure itself, specifically to quantify what a buyer, investor, or lender is about to inherit or take on risk against. The two serve entirely different purposes and are commissioned for different reasons.
In a share purchase, do we really inherit the target's entire tax history?
Yes. In a share acquisition, the legal entity does not change — you are buying shares in the same company that filed those returns and carries that tax history. Every open assessment, every pending TDS default, every unresolved appeal remains the liability of the company, and the company is now yours. This is the single most important reason share deals require deeper tax diligence than asset purchases, where liabilities generally do not follow specific assets to the buyer.
How far back does the reassessment window go, and why does that matter for diligence?
Under Section 148 (as amended), the standard reassessment window is 3 years from the end of the relevant assessment year. This matters directly for diligence scope: for a target with material transactions, undisclosed income exposure could in principle be reopened for up to a decade, which is why diligence for higher-risk targets goes back further than a routine 3-year review.
Getting This Right From the Start
Before you sign, know exactly what you are acquiring. Speak with a PNPC Chartered Accountant who has been finding, quantifying, and negotiating tax exposure out of Indian and UAE transactions since 1986 — not a template checklist, a senior practitioner who reads the numbers behind the numbers.
