In the M&A process, a Tax Due Diligence (TDD) report serves as a critical tool for identifying potential tax risks and quantifying liabilities. For investors and decision-makers, understanding the structure of this report is essential to interpreting the findings effectively.

Drawing from standard industry practices in Korea, here is an overview of how a comprehensive TDD report is structured and what information each section typically contains.

1. Executive Summary

The report begins with an Executive Summary, designed to give decision-makers a quick yet comprehensive overview of the target company’s tax health. This section is the most scrutinized part of the report.

• Summary of Key Findings: A high-level overview of the most significant tax issues discovered during the review.

• Quantification of Potential Risks: Issues are often categorized by tax type (e.g., Corporate Tax, VAT) and risk level (High/Medium/Low). The report provides an estimated monetary exposure for each issue, including potential principal tax, penalties, and interest.

• Overall Assessment: A professional opinion on the overall tax compliance status and material risks that could impact the deal valuation or structure.

2. General Tax Matters

Before diving into specific issues, the report establishes the context of the review.

• Scope and Limitations: Defines the period covered (usually the past 3 to 5 years based on the statute of limitations) and the scope of the review (e.g., limited to major tax items).

• Tax Filing History: A summary of the target company’s tax filing track record for Corporate Income Tax (CIT) and Value Added Tax (VAT).

• Audit History: Details of any past tax audits conducted by the National Tax Service (NTS) or local governments, including the outcomes and any assessments levied. This helps in understanding the company's historical relationship with tax authorities.

3. Detailed Review: Corporate Income Tax (CIT)

This section analyzes the target company’s compliance with corporate tax laws, focusing on the adjustments made between accounting profit and taxable income.

• Non-Deductible Expenses: A review of expenses that may be disallowed for tax purposes, such as excessive entertainment expenses, non-business related expenses, or undocumented payments.

• Labor-Related Costs: Examination of bonuses, severance payments, and retirement benefits for executives to ensure they meet the strict requirements of the Corporate Tax Act (e.g., existence of board-approved payment regulations).

• Depreciation and Capital Expenditures (CAPEX): Analysis of whether capital expenditures (e.g., facility construction, interior costs) were incorrectly expensed immediately instead of being capitalized and depreciated over time.

• Tax Credits and Exemptions: Verification of whether the company properly qualified for any tax incentives claimed (e.g., R&D tax credits, employment increase tax credits) and if there is a risk of recapture due to failure to meet post-claim requirements.

4. Detailed Review: Value Added Tax (VAT)

The VAT section focuses on the accuracy of tax invoices and the legitimacy of input tax deductions.

• Reconciliation of Revenue: Comparing the revenue reported on VAT returns with the revenue in the financial statements to ensure consistency.

• Input VAT Deductions: Scrutinizing input VAT deducted on purchases to ensure they are business-related. Common issues include deductions for non-business vehicles or entertainment-related costs.

• Zero-Rate and Exemptions: If the company engages in exports or specific exempt supplies, the report verifies that the necessary documentation (e.g., purchase confirmation letters, export declarations) is in place to justify the zero-rating.

• Timing of Issuance: Checking if tax invoices were issued and received at the correct "time of supply" to avoid penalties for late issuance or receipt.

5. Deal Implications & Other Tax Considerations

Finally, the report addresses tax issues that are triggered specifically by the transaction itself.

• Share Deal vs. Asset Deal: Implications differ based on the deal structure.

• Deemed Acquisition Tax (for Share Deals): In Korea, if an acquirer becomes a "major shareholder" (holding more than 50% of shares) of a company that owns real estate or vehicles, they may be liable for Deemed Acquisition Tax. The report calculates this potential liability.

• Secondary Tax Liability: Assessing whether the acquirer could be held secondarily liable for the target company’s unpaid taxes.

Conclusion

A well-structured TDD report does more than just list errors; it provides a roadmap for negotiation and post-merger integration (PMI). By understanding the typical components—from General Matters to specific CIT and VAT reviews—investors can better navigate the complexities of M&A taxation and make informed decisions.
