Accounting, tax, and business services in Thailand

Our monthly accounting service begins with an understanding of the business model, revenue and expense flows, payment channels, and the documents used in day-to-day operations. We then agree on a practical document cycle and bookkeeping workflow based on the company’s transaction volume.

We review tax invoices, receipts, purchase and sales documents, and bank activity before recording and reconciling key accounts. This supports consistent monthly tax work, annual closing, and management review without leaving avoidable issues until year end.

For foreign-owned companies in Thailand, we organize information so directors, local teams, and overseas finance personnel can communicate clearly while preserving the Thai statutory documents required locally.

Monthly tax filing depends on complete documents and correct transaction classification. We review payment types, recipients, input and output VAT, and the company’s registration status before preparing the relevant returns.

The scope may include withholding tax, VAT, payroll-related filings, and other recurring forms applicable to the business. We determine the required filings from the company’s facts rather than applying the same checklist to every entity.

A working tax calendar, document reminders, and pre-filing communication help management understand upcoming liabilities and resolve questions before the deadline.

Year-end work starts with a review of the full accounting period and reconciliation of cash, banks, receivables, payables, assets, inventory, payroll, and tax accounts. This identifies adjustments required before the financial statements are prepared.

We assemble supporting schedules and coordinate information with the independent auditor, including follow-up questions and additional documents, until the accounts are ready for approval and filing.

Management receives a clear explanation of significant matters in the statements, helping directors understand performance, financial position, and issues to plan for in the next accounting period.

Before incorporation, we discuss the proposed activities, shareholders, directors, capital, office address, and operating plan. This helps align the initial structure with the company’s objectives and relevant requirements.

We support the preparation of information and documents for juristic-person registration and review whether VAT, social security, or other registrations may be needed. Scope and timing are confirmed after an initial review.

After incorporation, we help outline the accounting documents, filing calendar, and internal responsibilities needed to begin operations on an organized basis.

Changes to directors, signing authority, shareholders, address, capital, or objectives may require different resolutions and supporting documents. We first determine the correct sequence and whether other authorities should also be notified.

We review the current company records, prepare the registration package, and check that applications, resolutions, corporate documents, and evidence are consistent.

After registration, we identify follow-on updates that may be needed with tax, social security, banks, counterparties, or licensing authorities so the company’s records remain aligned.

BOI support begins with the proposed activity, technology, workflow, investment, machinery, personnel, and market. We use these facts to assess how the project may relate to eligible activities and promotion conditions.

Where the route appears appropriate, we help structure the project information, Business Plan, and Financial Projection and coordinate the application documents and clarifications. Approval cannot be guaranteed before the authority completes its review.

After approval, we can help organize accounting, records, condition tracking, and reporting information so BOI obligations are integrated with the company’s normal operations.

A Foreign Business License assessment should begin with the activities the company will actually perform, its revenue, contracts, shareholders, and management roles. The analysis should not rely only on registered objectives or ownership percentages.

We help organize the business facts, consider relevant routes, and coordinate business descriptions, plans, and supporting documents for the selected approach. Timing and outcome remain subject to the facts and the authority’s review.

The licensing route is also considered alongside incorporation, tax, accounting, funding, staffing, and ongoing compliance so the proposed structure can operate in practice.

Foreign-owned companies often need to connect Thai statutory requirements with group policies. We review the chart of accounts, reporting timetable, ERP or working files, and information required by the overseas finance team.

We manage Thai bookkeeping, tax, and reconciliations within scope and can provide agreed English-language schedules or management reports so directors and regional teams can understand the local entity without losing Thai compliance context.

Where the company has BOI promotion, an FBL, a branch structure, or related-party transactions, we identify information that should be tracked separately and coordinate with other specialists where matters fall outside routine accounting.

Cross-border transactions may include services, royalties, interest, dividends, goods, or intercompany charges. Each category can require different evidence and accounting or tax treatment.

We map the transaction flow, review relevant agreements and documents from an accounting perspective, and identify the information needed for recording and reporting. Tax or legal specialists are coordinated where the matter requires advice beyond routine accounting.

For group companies, we can organize intercompany reconciliation schedules so the Thai entity’s records align with overseas counterparties and are ready for closing or audit.

This service supports businesses that need an address for corporate registration and relevant correspondence. The proposed activity, authorized persons, and intended use of the address must be reviewed before service begins.

The agreement sets out the scope, document-handling process, term, and identity requirements. Certain businesses or licences require premises with specific characteristics, so suitability must be assessed case by case.

The address service can be coordinated with company incorporation, an address change, and a document notification process so responsible persons know when official correspondence arrives.

Work permit and visa matters can depend on company status, capital, employment, salary, tax, social security, and applicant documents. We help review the company-side information and organize the supporting-document sequence.

Where immigration or labour specialists are required, we coordinate with relevant partners and support the corporate, accounting, tax, and employment documents included in the agreed scope.

This is a coordination and readiness service, not a guarantee of approval. Timing and outcome depend on the application type, qualifications, documents, and the authority’s review.
