Virtual Office with VAT Registration Support
Virtual Office พร้อมจดภาษีมูลค่าเพิ่ม (ภ.พ.20) · § Tax
Quick answer
Prepare the premises to pass a Revenue Department inspection, file Por Por 01 and follow through to the Por Por 20 VAT certificate.
Timeline: Site preparation 3–5 days; filing and inspection 2–4 weeks
Who this is for
- Companies crossing the 1.8 million baht annual revenue threshold
- Businesses whose corporate clients require full tax invoices
- Importers and exporters needing a VAT number for customs clearance
Documents required
- Current company affidavit
- Consent letter and house registration copy
- Photographs of the building, signboard and interior
- Location map and lease or service agreement
- ID of the authorised director
When VAT registration becomes mandatory
Under the Revenue Code, a business whose income from goods or services exceeds 1.8 million baht in a year must apply for VAT registration within 30 days of crossing the threshold. Below that level registration is voluntary.
Voluntary registration buys credibility with corporate buyers and allows input-tax credits, but it also creates a monthly Por Por 30 filing obligation even for nil months, plus input and output tax reports.
What the Revenue Department inspects on site
- A permanent, externally visible company signboard
- Usable workspace with desk, seating and office equipment
- A responsible person able to explain the business activity
- Occupancy documents matching the filing
- Consistency between the declared activity and the space used
Obligations after the Por Por 20 is issued
| Obligation | Deadline | Consequence of default |
|---|---|---|
| Monthly Por Por 30 filing | By the 15th of the following month | Surcharge and penalty under the Revenue Code |
| Issue compliant tax invoices | On each taxable event | Customers lose their input tax credit |
| Maintain input and output tax reports | Monthly | Assessment risk on audit |
| Display the Por Por 20 at the premises | At all times | Statutory fine |
| File Por Por 09 for changes | Within 15 days | Registry mismatch blocks refunds |
Common mistakes and how we avoid them
More questions we are asked
- Can a virtual office pass a Thai VAT inspection?
- Yes, provided the signboard is installed, the workspace is genuinely usable, someone can explain the business on site and the occupancy paperwork matches the application.
- Should I register voluntarily below the threshold?
- It depends on your buyers and cost base. Corporate customers who need full tax invoices and businesses with heavy input VAT usually benefit; consumer-facing businesses with little input VAT often do not.
Common mistakes and how to avoid them
- Filing before the signboard and workspace are ready
- Fix: Prepare and photograph the premises before submission
- Nobody on site during the inspection visit
- Fix: Arrange representation with a power of attorney to answer questions
