Closing 2025: Tax Basics, Key Changes and Practical Insights

As 2025 comes to an end, companies will be closing their books and preparing for annual tax obligations. With the new Corporate Income Tax law now in effect and Circular 99 starting 1 January 2026, this is the right time to revisit the basics and understand what these changes mean. In this session, we will also share observations on common audit risks as the tax authorities will be preparing their 2026 tax audit list in Quarter 1.

The session will cover fundamentals, key updates, and include an extended Q&A for your specific questions.

Highlights of the seminar:

• Year-End Corporate Income Tax Fundamentals – Key obligations, deadlines and practical tips for accurate CIT declarations
• Transfer Pricing & Related-Party Transactions – Basics of compliance and documentation and common pitfalls to avoid
• Tax Audit Outlook for 2026 – Preparing for tax audits and common findings and risk areas from recent experiences
• Accounting Changes Under Circular 99/2025/TT-BTC – What shifts from January 2026
• Extended Q&A Session.

The session will be led by our Partner, Kevin Lam and our Accounting and Tax Director, Mai Vu.
