Why Tax Due Diligence Matters
Business transactions often involve more than financial statements and legal documents. Hidden tax liabilities can significantly affect the value of an investment and may become the responsibility of the buyer after a transaction is completed.
Tax Due Diligence is a systematic review of a company's tax position to identify existing and potential tax exposures before a merger, acquisition, investment, restructuring, or other significant corporate event. By evaluating tax compliance, historical filings, tax risks, and outstanding obligations, businesses gain a clearer understanding of potential liabilities and opportunities.
Without proper Tax Due Diligence, organizations may face unexpected tax assessments, penalties, interest, compliance issues, or disputes that could reduce the anticipated value of the transaction.
At TGS AU Partners, we help businesses uncover these risks early, enabling clients to negotiate transactions with greater confidence, strengthen their bargaining position, and develop effective risk mitigation strategies before agreements are finalized.
What is Tax Due Diligence?
Tax Due Diligence is a comprehensive examination of a company's tax affairs conducted before significant corporate transactions. The objective is to evaluate whether the target company has complied with applicable tax regulations and to identify any historical or future tax exposures that could affect the transaction.
Our review extends beyond simply checking tax returns. We examine the company's overall tax profile, including compliance history, tax positions, accounting treatments, supporting documentation, tax incentives, transfer pricing arrangements, and ongoing disputes with tax authorities.
The findings allow investors, shareholders, lenders, and management teams to understand:
- Potential unpaid tax liabilities
- Compliance deficiencies
- Tax audit exposure
- Risks associated with aggressive tax positions
- Opportunities for tax optimization
- Financial implications of identified risks
By identifying these issues before a transaction is completed, businesses can make informed investment decisions, negotiate purchase prices more effectively, or request appropriate indemnities from sellers.
When Do You Need Tax Due Diligence?
Tax Due Diligence is valuable in many business situations where understanding tax risks is essential.
Mergers and Acquisitions (M&A)
Before acquiring or merging with another company, investors need confidence that undisclosed tax liabilities will not become unexpected financial burdens after completion.
Business Acquisitions
Acquiring an existing business requires more than reviewing financial performance. Tax Due Diligence identifies historical tax compliance issues, unpaid obligations, and potential exposures that may affect the transaction value.
Investment Transactions
Private equity firms, venture capital investors, family offices, and strategic investors often perform Tax Due Diligence before investing to better understand tax risks associated with the target company.
Corporate Restructuring
Business reorganizations may create tax consequences that require careful analysis. Tax Due Diligence helps evaluate existing obligations and future tax implications before restructuring activities begin.
Joint Ventures
When entering a new partnership, understanding each party's historical tax compliance helps reduce uncertainty and supports more effective negotiations.
IPO Preparation
Companies preparing for public offerings should ensure their historical tax compliance is well documented before entering the capital market.
Our Tax Due Diligence Services
At TGS AU Partners, our Tax Due Diligence engagements are tailored to the nature of each transaction. We assess tax risks comprehensively while providing commercially practical recommendations that support informed decision-making.
Our review may include:
Corporate Income Tax Review
We examine historical Corporate Income Tax filings, fiscal reconciliations, deductible expenses, tax loss carry-forwards, deferred tax positions, and compliance with Indonesian tax regulations.
Value Added Tax (VAT)
Our specialists review VAT reporting processes, input and output VAT, tax invoices, VAT refunds, and potential exposures arising from incorrect VAT treatments.
Withholding Tax
We evaluate compliance relating to withholding tax obligations, including Articles 21, 23, 26, and Final Income Tax under Article 4(2), identifying potential underpayments and reporting deficiencies.
Transfer Pricing
For companies engaged in related-party transactions, we assess transfer pricing documentation, pricing methodologies, benchmarking analyses, and compliance with prevailing regulations.
Tax Incentives
Where applicable, we review the utilization of tax incentives, investment allowances, tax holidays, super deductions, and other government facilities to verify compliance with eligibility requirements.
Tax Audits and Disputes
Our professionals assess ongoing or historical tax audits, objections, appeals, and litigation matters to understand their financial implications and potential impact on the transaction.
Payroll Taxes
We review payroll tax compliance, employee income tax obligations, benefit taxation, and employer reporting requirements.
Tax Compliance Review
Our team examines the completeness and accuracy of tax filings, payment history, supporting documentation, and compliance procedures to identify weaknesses that may require corrective action.
Common Tax Risks We Frequently Identify
During Tax Due Diligence engagements, businesses commonly encounter issues such as:
- Incomplete tax documentation
- Incorrect VAT treatment
