Form 50 Tawi, also known as "Certificate of Tax Withholding under Section 50 Tawi of the Revenue Code," is a document issued by the payer who withholds tax from payments made to the payee, such as salaries, wages, commissions, or other income. This certificate is provided to the payee as evidence for annual income tax filing (Form P.N.D. 90 or P.N.D. 91).
In this article, we will introduce you to Form 50 Tawi and what you need to know about issuing this form, as well as how to use it for tax filing to make it easier to understand.
Who needs to issue Form 50 Tawi?
Many people might mistakenly believe that Form 50 Tawi must be issued by the Revenue Department. In reality, Form 50 Tawi must be issued by the "employer" or "payer," which can be either an individual or a legal entity that makes payments to employees or recipients. This form serves as evidence for withholding tax from various types of income, such as salaries, wages, bonuses, and commissions.
Form 50 Tawi can be issued in either Thai or English. If it is issued in another language, a Thai translation must be included.
How to Issue Form 50 Tawi
In the case of salary or wage payments:
For employees working until the end of the year: The employer must issue Form 50 Tawi to the employee by February 15th of the following year.
For employees leaving during the year: If an employee leaves during the year, the employer must issue Form 50 Tawi within one month after the employee's departure date.
In the case of other types of income
For other types of income that require withholding tax under Section 40 (3), (4), (5), (6), (7), (8), the employer must issue Form 50 Tawi immediately upon withholding the tax.
Issuing a Replacement Form 50 Tawi
If an employee loses or damages Form 50 Tawi, they can request the employer to issue a replacement. To issue a replacement, the employer can make a copy of the original Form 50 Tawi and write "Replacement" at the top of the document, along with a signature for verification.
Why is Form 50 Tawi important?
