Virtual Office with VAT Registration Support

When VAT registration becomes mandatory

A business with taxable sales or services exceeding THB 1.8 million annually must apply for VAT registration within 30 days of crossing the threshold. Exempt activities and voluntary registration have separate conditions. Confirm the activity with the Revenue Department; input-tax credit or refunds are subject to eligibility and evidence.

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

Common mistakes and how we avoid them

More questions we are asked

Can a virtual office pass a Thai VAT inspection?

It may be considered, but the Revenue Department decides each application. Genuine occupancy rights, truthful photographs and usable space are supporting evidence, not an approval guarantee.

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.
