Thailand VAT Registration | Ph.Ph.01 & Premises Evidence
Assess the activity and registration basis before preparing Ph.Ph.01. Separate application filing from approval, and plan ongoing VAT work around actual transactions.

Check taxable activity before applying the turnover threshold
A business carrying on VAT-taxable sales or services should assess registration when annual turnover exceeds THB 1.8 million. Exempt activities must be identified separately: crossing the threshold does not make every exempt business liable to register. Turnover is not the same as profit, and bank deposits alone do not establish the tax treatment of every receipt.
Voluntary registration may be available subject to the applicable conditions. Choosing it creates ongoing invoice, record and return obligations; it is not simply a way to give a corporate customer a different document. Tell our team what you sell, where the transactions occur and whether you already have a VAT registration.
Prepare a registration file that matches the real premises
- Company registration records, directors and authorised signatories, with the proposed head-office and branch details.
- A description of actual goods or services and turnover records to distinguish taxable and exempt activities.
- Evidence of the right to occupy the premises, such as a lease or owner consent and supporting documents required for that case.
- A map and photographs of the real business premises, with address and business signage consistent with the application.
- Existing VAT records where relevant and representative authority if someone files on the company's behalf.
This is a preparation list, not a universal filing checklist. The applicant, premises arrangement and responsible Revenue office affect the evidence requested. The official premises guide linked below covers locations outside Bangkok; confirm Bangkok requirements separately rather than substituting that guide.
Ph.Ph.01 is an application, not the VAT certificate
We first assess the business details and premises evidence, then agree the filing scope and an available submission channel. The Revenue Department can request clarification or inspect the premises. Submitting Ph.Ph.01 does not itself establish approval: Ph.Ph.20 is the registration certificate.
Check the effective registration date before treating the company as VAT registered or issuing invoices on that basis. A company representative should be ready to explain its real operations. Approval remains with the Revenue Department; our quotation does not promise a fixed decision date or guaranteed outcome.
VAT-capable addresses at our two real offices
Our Bangkok address at 61 Soi Lat Phrao 95 and Khon Kaen head-office address at 680/45 Na Mueang Road support VAT registration. Agree the right-to-use evidence and arrangements for any premises inspection with our staff. Address availability does not replace an assessment of the particular company's application.
Specify whether the request is a first registration, relocation or additional branch. A change in the company's DBD records does not by itself complete the corresponding notification to the Revenue Department. Company-registration work, premises documentation and VAT filings should be identified separately in the quotation.
Monthly returns and foreign-service payments are separate checks
A VAT registrant has monthly Ph.Ph.30 filing obligations, including months without sales. Review output VAT, eligible input VAT and supporting tax invoices, and maintain the reports applicable to the business. Inventory records should be assessed against actual goods activity rather than assumed identical for every service company.
Ph.Ph.36 concerns remittance in specified circumstances, including certain payments for overseas services used in Thailand. It is not an additional monthly return automatically required of every company. Review the supplier, use of the service and relevant VAT arrangement before deciding how a particular payment is handled.
e-Tax Invoice onboarding is not automatically mandatory for every new VAT registrant. If electronic invoicing is needed, assess the relevant system and eligibility separately from registration. Moving, adding a branch or closing a business also requires a review of notification procedures and outstanding obligations; falling sales alone is not a reason to stop filing.
Request a quotation with a defined scope
Send the business activity, approximate turnover, current VAT status, intended premises and transaction start date. State whether you need registration only, changes to existing records, premises coordination or ongoing reports and monthly returns. Contact our team for a quotation; company service prices are not displayed here.
For an initial review, use legible copies and remove unnecessary personal information. Do not send tax-account passwords or one-time codes in ordinary messages. Agree filing authority and a suitable document-transfer method before work starts.
Questions foreign clients commonly need to separate
Does importing goods mean the business must register?
Import VAT and domestic VAT registration are distinct issues. Check the taxable business activity, threshold and applicable conditions; importing alone is not a universal registration test.
Is overseas e-service registration the same system?
The overseas electronic-service regime is distinct from ordinary domestic VAT registration. Identify the supplier, customer and transaction first instead of applying a domestic Ph.Ph.01 checklist to every foreign business.
Do returns continue in a month with no sales?
VAT registrants still have monthly Ph.Ph.30 filing duties in months without sales. Confirm any later cancellation or status change through the proper process before stopping.
