There have been a number of recent changes and updates with respect to employee personal tax allowances so this is an opportune time to provide readers of RSM Focus with relevant information regarding the latest payroll outsourcing Bangkok tax news. An individual, resident or non-resident, who derives assessable income from employment in Thailand or from income sourced in Thailand, is liable to report their income and pay taxes at the progressive tax rate of 0% - 35% (if any) via filing their Thai annual tax return (PND 90/91). This is regardless of where the income is paid.

What are personal allowances and / or deductions?

The Thai Revenue Department allows an individual to claim personal allowances and deductions from net income after the deduction of standard expenses according to Thai tax laws. This can help individuals to minimize their tax liabilities by offsetting them against assessable income before calculating their tax liabilities.

As you may be aware the Thai Revenue Department always updates/announces additional personal allowances and deduction each year to support tax payers or also to make things easier and fairer when economic situations dictate a need during particular periods of turbulence or other.

As taxpayers, you should be aware of some of the personal allowances and deductions which may have been discontinued. Therefore, below is an updated personal allowances and deductions summary which are still applicable for the tax year 2021.
