Corporate Income Tax Position Review

Data sources: Last 3 years ITRs, tax computation sheets, assessment orders, CBDT communication history

This dimension reviews the company’s income tax position across three years — examining the Effective Tax Rate against the statutory benchmark (25.17% under Section 115BAA), identifying specific deduction and exemption claims made versus available, assessing the treatment of all significant transactions (capital gains, related-party payments, exceptional items), and reviewing the consistency of positions across assessment years. Key red flags: ETR above 27–28% without structural explanation; Section 40(a)(ia) disallowances from TDS gaps inflating taxable income; Section 43B timing failures on employee benefits; Section 14A over-disallowances; missed accelerated depreciation claims; and inconsistent treatment of provisions versus actual payments across assessment years. For a ₹50–200 crore company, the ETR optimisation opportunity typically ranges from ₹40 lakh to ₹2 crore annually — identified and actionable within the current assessment year in most cases.

TDS Compliance Audit

Data sources: Form 26AS, TRACES TDS returns, payment registers, vendor master, payroll records

The TDS compliance audit reviews every payment category above ₹1 lakh — contractors (194C), professional fees (194J), rent (194I), interest (194A), commissions (194H), purchases above ₹50 lakh aggregate (194Q), business benefits (194R), and all other applicable TDS provisions — against the company’s actual deduction and deposit records. For a company with 100+ vendors, this review typically identifies 3–7 categories with systematic non-deduction or under-deduction. Every identified TDS gap creates: interest exposure under Section 201(1A) at 1–1.5% per month from the original payment date; penalty exposure under Section 271C equal to the undeducted TDS amount; and a 30% disallowance of the underlying payment under Section 40(a)(ia) — permanently inflating taxable income for the affected year. The TDS audit quantifies the aggregate financial exposure from all identified defaults and recommends the optimal remediation approach — including voluntary disclosure to TRACES where applicable.

GST Compliance Review

Data sources: GSTR-1, GSTR-3B, GSTR-2B, GSTR-9/9C, e-way bill portal, GST portal notices

The GST compliance review covers: ITC utilisation ratio vs. GSTR-2B availability (target: 90%+); GSTR-2B vs. GSTR-3B reconciliation across all open periods; GSTR-9/9C consistency with audited financial statements; classification and rate application on outward supply; Section 17(5) blocked credit application accuracy; ISD distribution compliance (where applicable); and e-way bill vs. GSTR-1 consistency. For a ₹100 crore company, a 10% ITC leakage represents ₹1.5–3 crore in blocked or lost working capital annually. The GSTR-9/9C reconciliation review specifically identifies variances between GST-declared turnover and book turnover — every unexplained variance is a potential ASMT-10 scrutiny notice trigger under CBIC’s automated reconciliation engine.

Transfer Pricing Documentation Status

Data sources: Form 3CEB filings, Master File, Local File, intercompany agreements, related-party transaction register

This dimension reviews the status and quality of Transfer Pricing documentation for all international related-party transactions — intra-group services, product supply, royalties, management fees, cross-border loans, and guarantees. For companies with domestic related-party transactions above ₹5 crore, it also reviews the GST Rule 28 valuation compliance and income tax related-party transaction characterisation. Key red flags: Form 3CEB filed late or not filed; documentation not updated to reflect current-year transaction volumes and pricing; new transaction categories initiated during the year without documentation; and intercompany agreements that are either absent or materially inconsistent with how transactions actually operate. The penalty for undocumented international related-party transactions is 2% of full transaction value under Section 271AA — regardless of whether the pricing is arm’s length. For a company with ₹30 crore in annual related-party imports and ₹20 crore in management fee payments, inadequate documentation creates a ₹1 crore penalty exposure on each documentation gap year.

CBDT Scrutiny Risk Assessment

Data sources: Filed ITRs vs GSTR data, bank statement analysis, SFT submissions, AIS/TIS statements

This is the most forward-looking dimension — it analyses your company’s tax position through CBDT’s Project Insight lens, identifying the specific patterns that the algorithmic scrutiny selection system is most likely to flag. The assessment cross-references: ITR-declared turnover vs GSTR-1 turnover (mismatch above 1% is a primary scrutiny trigger); bank credit entries from the Annual Information Statement (AIS) not matched to ITR income; related-party transactions that deviate from arm’s length without documentation; TDS deduction gaps that create Section 40(a)(ia) disallowance risk; and any Section 56(2)(viib) issues from capital received at premium. For companies above ₹50 crore in the manufacturing, IT services, real estate, and financial services sectors, the scrutiny selection probability is estimated at 2–5% annually based on available CBDT data. The Scrutiny Risk Assessment produces a Scrutiny Risk Score and a prioritised list of positions that must be documented or corrected before the current year’s ITR is filed.

FEMA and Cross-Border Compliance

Data sources: EDPMS export data, eBRC records, outward remittance records, Form 15CA/15CB, overseas investment filings

For companies with any cross-border dimension — exports of goods or services, import of services, technical collaboration agreements, overseas subsidiary investments, or foreign borrowings — this dimension reviews FEMA compliance across all applicable RBI regulations. Key review areas: export proceeds realisation within 9 months from invoice date; eBRC filing for all export invoices; Form 15CA/15CB for all outward remittances; annual return on Foreign Liabilities and Assets (FLA) filing compliance; overseas direct investment (ODI) filings for companies with foreign subsidiaries; and documentation for advance received against exports. FEMA contraventions that are not compounded are non-compoundable after a certain threshold — and carry penalty exposure of up to 3× the foreign exchange amount involved. For a company with ₹40 crore in annual service exports and a history of 9-month realisation non-compliance, the FEMA exposure can be material.

Tax Litigation Portfolio Review

Data sources: All income tax, GST, TDS, and customs notices received; CIT(A) and ITAT orders; demand register

Many mid-market companies do not have a consolidated, current view of all outstanding tax demands, notices, and appeals across all entities, all tax heads, and all jurisdictions. The Litigation Portfolio Review creates a single, structured register covering: every outstanding notice across income tax, GST, TDS, customs, PF/ESI, and state levies; the current stage of each matter; upcoming response and hearing deadlines; the probability-weighted outcome for provisioning purposes; the recommended legal strategy for each matter; and the aggregate total exposure across all matters. For listed companies and PE-backed businesses, this register is a mandatory component of board risk reporting. For companies approaching a fundraise or M&A transaction, the litigation portfolio is among the first three areas reviewed in tax due diligence — and untracked or inadequately provided matters are among the most common deal-structuring complications in Indian M&A.

Board-Level Tax Governance

Data sources: Board resolution records, delegation of authority matrix, audit committee charter, tax policy document

Tax governance is the dimension most mid-market companies have never thought about — yet it is the one that determines whether all other dimensions are being managed systematically or reactively. Key governance elements reviewed: Does the company have a written Tax Policy approved by the Board? Is there a documented Delegation of Authority matrix specifying who may take tax positions, approve large payments with tax implications, or sign notices and appeals? Does the Audit Committee receive a quarterly tax risk report? Is there a documented Notice Response Protocol ensuring specialist review of all tax notices before response? Has the CFO or Finance Director received a formal briefing on the company’s current tax risk register? For PE-backed and listed companies, weak tax governance is a management control deficiency that auditors and investors treat as a red flag — independent of the quantum of any specific tax exposure.

Q1: Why is ₹50 crore turnover the critical threshold for a tax health check?

At ₹50 crore turnover, a company simultaneously crosses: mandatory tax audit under Section 44AB of the Income Tax Act; higher weight in CBDT’s risk-based scrutiny selection algorithm; mandatory Transfer Pricing documentation requirements under Section 92D for international related-party transactions; entry into CBIC’s GST audit selection criteria; and the size threshold at which PE funds, strategic buyers, and banks conduct detailed tax due diligence. Each of these transitions creates new compliance obligations and new enforcement risks that a company’s existing filing-only CA relationship is typically not equipped to manage.

Q2: What are the 8 dimensions of a comprehensive Tax Health Check?

The 8 dimensions are: (1) Corporate Income Tax Position Review — ETR analysis, deduction completeness, and position consistency; (2) TDS Compliance Audit — all payment categories, defaults, and Section 40(a)(ia) disallowance risk; (3) GST Compliance Review — ITC utilisation, GSTR-2B reconciliation, and annual return consistency; (4) Transfer Pricing Documentation Status — Form 3CEB completeness and current-year benchmarking; (5) CBDT Scrutiny Risk Assessment — algorithmic trigger analysis using Project Insight criteria; (6) FEMA and Cross-Border Compliance — export realisation, remittance documentation, ODI filings; (7) Tax Litigation Portfolio Review — consolidated register of all outstanding notices and demands; and (8) Board-Level Tax Governance — Tax Policy, Delegation of Authority, and Audit Committee reporting.

Q3: How long does a Tax Health Check take for a company between ₹50 crore and ₹500 crore?

A comprehensive 8-dimension Tax Health Check for a company between ₹50 crore and ₹500 crore typically takes 3–5 weeks from data access to final Risk Register delivery. Week 1 covers data collection and review of Dimensions 1–3; Week 2 covers Dimensions 4–6; Week 3 covers Dimensions 7–8 and cross-dimension analysis; Weeks 4–5 are used for remediation recommendations, Risk Register preparation, and Board or Audit Committee presentation. For companies above ₹500 crore or with multi-entity structures, the timeline extends to 6–8 weeks.

Q4: Why must the Tax Health Check be conducted by a firm independent of the filing CA?

Independence is critical for three reasons: (1) The filing CA has a commercial incentive not to identify problems that imply their own prior-year work was suboptimal — creating a structural conflict of interest in any self-review; (2) The Health Check requires specialist risk management, litigation, and cross-disciplinary tax expertise beyond the compliance scope of most filing CA relationships; (3) In subsequent PE due diligence, M&A transactions, or litigation proceedings, a health check conducted by an independent specialist is significantly more credible than one conducted by the filing CA. Rudra Capital conducts all Tax Health Checks as fully independent engagements, separate from any filing relationship with the company.

Q5: What is the typical financial impact identified in a Tax Health Check for a ₹50–200 crore company?

Based on Rudra Capital’s experience across 200+ health checks, the typical findings for a ₹50–200 crore company include: TDS default exposure of ₹40 lakh–₹2.5 crore across multiple vendor categories; GST ITC utilisation gap of ₹50 lakh–₹3 crore in blocked or lost working capital; ETR above benchmark by 2–5 percentage points, representing ₹40 lakh–₹1.5 crore in unnecessary tax; Transfer Pricing documentation gaps creating 2% penalty exposure on typically ₹5–50 crore in related-party transactions; and at least one open scrutiny risk trigger that can be addressed pre-notice with pre-emptive documentation. Total identified exposure in a first-time health check engagement averages ₹1.5–7 crore for this company size band.

Q6: How does a Tax Health Check help with a PE fundraise or M&A transaction?

In a PE fundraise or M&A transaction, the investor or buyer’s tax due diligence will cover all 8 dimensions of the health check framework. Companies that discover exposures for the first time in the investor’s due diligence face: valuation adjustments of 3–5x the exposure quantum (capitalised risk value); escrow holdbacks against identified contingent liabilities; warranty and indemnity insurance exclusions for known tax issues; and potentially deal re-pricing or deal failure for material unresolved exposures. Companies that conduct their own health check first arrive at the due diligence table with identified exposures already quantified, provisioned, and with remediation plans in place — dramatically improving the due diligence outcome and the valuation conversation.

Q7: What is CBDT’s Project Insight and how does it affect scrutiny selection for mid-market companies?

CBDT’s Project Insight is India’s AI-powered tax return analysis and scrutiny selection system. It processes filed income tax returns within 60 days of filing and cross-references them against GST filings, bank SFT data, property registrations, import-export records, and social media for lifestyle indicators. It algorithmically identifies specific patterns — ITR-GST turnover divergence, unexplained bank credits, related-party transactions at off-market terms, high deduction claims, TDS gaps — and queues matching returns for scrutiny. For mid-market companies above ₹50 crore, the estimated scrutiny selection probability is 2–5% annually based on available CBDT statistical data. The Scrutiny Risk Assessment dimension of the Tax Health Check analyses your return through the same lens Project Insight uses — identifying your highest-risk positions before the algorithm does.

Q8: When should a company conduct a Tax Health Check — and how frequently?

The optimal annual timing is 2–3 months before the income tax return filing deadline — allowing identified issues to be addressed in the current year’s return. Mandatory additional triggers include: before any PE fundraise, M&A transaction, IPO, or major bank credit facility; when the company crosses ₹50, ₹100, ₹250, or ₹500 crore in annual turnover; after any corporate restructuring, acquisition, or addition of a new business line; when key finance personnel change; and whenever the company receives any tax notice, scrutiny communication, or GST audit notice in the prior 12 months. Companies that conduct annual health checks consistently report lower ETRs, zero missed TDS deadlines, and significantly reduced litigation exposure compared to peers without structured annual tax reviews.
