Withholding tax (WHT) is a form of pre-collected tax that is deducted from certain payments made in Phuket and the rest of Thailand. The purpose of WHT is to collect tax from individuals and businesses before they receive their full payment, ensuring that the government receives its revenue upfront.
Types of Income Subject to WHT
WHT applies to various types of income, including:
- Employment income: Salaries, wages, bonuses, commissions, and other forms of compensation paid to employees.
- Service and professional fees: Payments made for services rendered by individuals or businesses, such as legal, accounting, consulting, and engineering services.
- Rents: Income earned from renting out properties, such as apartments, houses, and commercial spaces.
- Interest income: Interest earned on bank deposits, bonds, and other investments.
- Royalties: Payments made for the use of intellectual property, such as patents, trademarks, copyrights, and industrial designs.
- Dividends: Income distributions from companies to their shareholders.
WHT Rates
The applicable WHT rate depends on the type of income and the tax status of the recipient. For instance, WHT rates for employment income range from 0% to 35%, while the rate for service and professional fees is typically 3% for residents and 15% for non-residents.
Responsibility for Withholding Tax
The responsibility for withholding tax lies with the person or entity making the payment. For example, employers withhold WHT from their employees’ salaries, while companies withhold WHT from payments made to service providers.
Filing and Payment of WHT
The withheld tax must be filed and paid to the Revenue Department within a specified timeframe, usually within the month following the payment. Companies can file and pay WHT electronically through the e-withholding tax system.
Penalties for Non-Compliance
Failure to withhold, file, or pay WHT can result in penalties, including fines and interest charges.
Purpose of WHT
WHT serves several important purposes:
- Ensures timely collection of tax revenue: By collecting tax upfront, the government ensures a steady flow of revenue and minimizes the risk of tax evasion.
- Simplifies tax administration: WHT reduces the administrative burden on taxpayers by shifting the responsibility of tax withholding to the payer.
- Promotes tax compliance: The threat of penalties encourages taxpayers to comply with WHT requirements.
- Facilitates cross-border transactions: WHT rules are often incorporated into double tax treaties, ensuring that taxes are collected in the appropriate country.
In summary, withholding tax plays a crucial role in Thailand’s tax system, ensuring that the government collects its revenue efficiently and promoting tax compliance among individuals and businesses.
