Frequently Asked Questions
What is Thai withholding tax (WHT)?
It is tax deducted at source by the payer before paying income to a vendor or freelancer. Rates vary by income type: 3% for services, 5% for rent, 2% for professional fees and advertising, among others. The payer remits it to the Revenue Department using a PND form.
When should I use net-to-gross solve mode?
When you want to receive a specific net amount after tax. For example, if a client agrees to pay you 10,000 THB net, the gross-to-net solve mode computes the gross invoice amount and the WHT to deduct.
What is the difference between PND.3 and PND.53?
PND.3 is for individual payers or unregistered businesses withholding from taxable income. PND.53 is for registered companies withholding from service fees, rent, and professional fees paid to other companies or individuals.
Are the WHT rates always the same?
The rates shown reflect the standard rates under the Thai Revenue Code. Specific treaty rates, government exemptions, or temporary reductions may apply - always verify with the Revenue Department or a tax advisor.
