How it works in a data room
Tax advisers request several years of corporate tax returns, indirect tax filings, payroll tax records, transfer pricing documentation, correspondence with tax authorities and details of any open audits. These usually sit in a dedicated tax folder with access limited to tax specialists on each side. For groups operating in several countries, subfolders by jurisdiction help reviewers move quickly. Questions about specific positions are logged through Q&A so the answers can be referenced in the tax report.
Why it matters in a deal
Tax exposures often survive a change of ownership, so a buyer inheriting a company also inherits its tax history. Findings shape the tax indemnity in the purchase agreement and may influence whether the buyer chooses a share or asset deal. Insurers writing warranty and indemnity insurance read the tax report closely and often exclude known issues. Our India guide and other country guides note where local tax and data rules interact.
Example
A US buyer reviewing an e-commerce company finds that it has been selling into many states without collecting sales tax since remote sellers became liable in most of them. The financial due diligence team quantifies the exposure, and the parties agree a special escrow from the price to cover any back taxes assessed within four years of closing.
