Accounting & Tax Support for Companies with Overseas Shareholders

This service is for Thai companies that need local accounting and tax work together with information suitable for directors, shareholders or finance teams outside Thailand.

The work may cover regular monthly records, Thai tax filings, year-end preparation and related corporate coordination. The exact scope depends on the company's activities, registrations, transaction volume and reporting requirements.

  • Thai limited companies with foreign shareholders
  • Thai subsidiaries of overseas groups
  • Companies with foreign directors
  • Businesses reporting to regional or overseas headquarters

What WMC Can Support

The following areas can be included where they form part of the agreed engagement.

Reporting for Overseas Management

Foreign shareholders and overseas management often need financial information in a format they can review without relying only on Thai-language statutory documents.

Where required, accounting information, schedules and management explanations can be provided in English. The format, frequency and level of detail are agreed as part of the engagement.

This may help an overseas parent company review local balances, understand open accounting matters and follow the status of recurring Thai filings.

Situations Where This Support May Be Useful

This type of support may be relevant when a new accounting process is needed or management requires a better view of the existing records.

  • A newly incorporated Thai subsidiary starting monthly accounting
  • An overseas parent company requiring visibility over local accounts
  • A company preparing to change its accounting provider
  • Incomplete records that need review before regular monthly work begins
  • Management requiring support with recurring Thai filing requirements

Taking Over from Another Accounting Provider

WMC can take over ongoing accounting work after reviewing the available information and the current status of the accounts.

The initial review may cover:

  • Opening balances and prior financial statements
  • Prior tax filings
  • Bank reconciliations
  • Accounting records and outstanding items
  • Available invoices, receipts and other supporting documents

The transition scope, responsibilities and starting date are agreed after the review. Historical issues may require separate work before the regular monthly process can begin.

Accounting Cleanup Where Records Are Incomplete

If accounting records are incomplete, overdue or inconsistent, WMC may need to carry out a separate review before accepting regular monthly work. This review can identify missing periods, differences in balances, filing gaps and supporting documents that still need to be collected.

The cleanup scope depends on the records available and the number of periods involved. WMC does not assume that every historical issue can be resolved immediately.
