Renting an office in Bangkok involves more than just the rental rate. Understanding office rent Bangkok tax, VAT, and other related costs is essential for tenants when leasing office space in Thailand.

Key Costs to Know

When renting office space in Bangkok, tenants should be aware of the following:

• Withholding Tax
• Value Added Tax (VAT)
• Stamp Duty
• Insurance

Withholding Tax Explained

In Thailand, tenants are required to withhold tax when making payments to the landlord:

• 5% withholding tax applies to the rental portion
• 3% withholding tax applies to service fees (such as cleaning, security, and utilities)

This amount is deducted from the payment and submitted to the Revenue Department on behalf of the landlord.

VAT on Office Rental

When renting office space in Bangkok, the total cost is typically divided into two parts:

• Rental (Rent)
• Service Charge

VAT (Value Added Tax) is charged at 7% on service charges only.

This typically applies to:

• Common area maintenance
• Cleaning services
• Utilities and building services

In most office buildings, landlords structure the pricing into these two components. A common breakdown is:

• 40% Rent / 60% Service Charge, or
• 50% Rent / 50% Service Charge

This may vary depending on the building.

For example:

If the total office cost is THB 100,000 per month

• Rent: THB 50,000
• Service charge: THB 50,000
• VAT 7% applies only to service charge = THB 3,500

Total payable: THB 103,500

Understanding this structure is important, as VAT is calculated only on the service charge, not the total rent.

Stamp Duty

Lease agreements in Thailand are subject to stamp duty.

This is typically a small cost and is usually paid by the tenant upon signing the lease agreement.

Third-Party Liability Insurance (Why It Matters)

The landlord provides building insurance for the property. However, tenants are required to obtain third-party liability insurance to cover any damage or injury caused to others within the building. This helps protect your business from unexpected liabilities and financial risk.

This is important because incidents inside your office unit can affect common areas or other tenants.

For example:

• A water leak from your pantry floods neighboring units or damages the lift
• An electrical issue in your office causes damage to the building
• A visitor slips inside your office and gets injured

In these cases, the tenant may be responsible for repair costs or compensation.
Third-party liability insurance helps cover these unexpected expenses.

Common Questions from Tenants

Do I really need to pay withholding tax?
Yes, if your company is registered in Thailand, withholding tax is required by law.

Who pays VAT?
VAT is paid by the tenant on applicable service charges.

Can landlords include tax in the rent?
In some cases, landlords may structure pricing differently, but typically taxes are handled separately.

Here’s a quick look at where the Bangkok office market is heading in 2026 — and what it means for tenants.

Grade A Rental Rates

Expect to pay between 900–1,500+ THB/sqm.

Note: The newest “Grade A+” buildings in Ploenchit and Wireless Road are pushing the top end of this range.

Grade B Rental Rates

Generally range from 600–850 THB/sqm.

Tip: This represents a significant saving for companies that don’t require a “status” address but still want to be close to the BTS.

The “Flight to Quality”

Many companies are moving up from Grade B to Grade A as landlords offer attractive incentives, such as longer rent-free periods, to fill new office towers.

What This Means for Tenants

2026 is shaping up to be a tenant-friendly market, especially for companies willing to explore both Grade A and Grade B options strategically.

The key is understanding effective rent, not just headline asking rates.
