Direct answers
Tax Filing Only Thailand: frequently asked questions
Practical answers before choosing your service scope.
Can we keep our overseas accounting team?
Yes. This service is intended for companies whose existing finance team prepares the books and filing-ready figures. UnionSPACE coordinates the agreed Thai submissions through the appropriate company accounts and authorisations. It does not require you to transfer the bookkeeping engagement.
What is included in the THB 65,000 annual fee?
The annual flat fee covers one company’s agreed applicable monthly and annual filings. The scope can include salary and payment withholding returns, VAT, Social Security, corporate income tax submissions and DBD filings. Specific business tax, transfer-pricing disclosure and local tax items are confirmed where applicable. The engagement defines the included forms and excludes actual taxes, official charges, penalties and additional professional work unless expressly agreed.
What must our accounting team provide?
Provide the completed figures, supporting schedules and approvals listed in the agreed filing checklist. For corporate income tax, your team supplies the tax computation. We arrange submission and filing evidence; preparation of the accounts, tax calculations and validation of the underlying records remain outside this filing-only scope.
What happens if data arrives late?
Late or incomplete figures can delay submission and create tax, surcharge or penalty exposure. We agree data cut-offs, issue reminders and tell you what remains outstanding. Actual statutory amounts depend on the filing and circumstances and are separate from the service fee.
Does the fee include preparing the corporate tax computation?
No. Your accounting team prepares the computation for P.N.D.50 and P.N.D.51 and provides the approved figures. Thai tax computation support or advice can be agreed under a separate engagement.
Is annual DBD submission included?
Submission of the agreed audited financial statements and post-meeting shareholder list is included where applicable. Your company provides the completed, approved documents. Preparing the accounts, performing the audit, organising the AGM, drafting meeting documents and auditor liaison are separate tasks unless expressly included.
Who is this service suitable for?
It suits a company with an established local or overseas finance team that can provide accurate filing-ready figures but wants a dedicated team to manage agreed Thai submissions and filing records. Businesses that need bookkeeping, management accounts or tax advice should consider the full accounting service.
