About the Role

As Assistant Tax Manager, you will be the day-to-day owner of tax compliance for an assigned portfolio of Thailand entities, with an emphasis on applying automation tools for efficiency.

Qualifications

• Bachelor's degree in Accounting, Finance, Taxation, Law or Economics; CPA, CPD, TA or equivalent professional qualification is a strong plus.
• 4–8 years of relevant tax experience gained in a Big 4 firm, in-house tax function of an established multinational, or a combination of both.
• Hands-on experience preparing tax returns and supporting tax audits with the Thai Revenue Department.
• Comfortable extracting and reconciling data from ERP systems and working with large datasets in Excel.
