Tell TRÍ TÍN about your business's situation

For real issues your business is facing: a notice you have just received, a situation you are unsure how to handle, or a decision you are weighing.

Who is this for?

Suitable: a real situation at your business (already operating, or preparing to be set up).

Not suitable: academic questions, exercises or general knowledge. You can look these up in our Knowledge section or in the original documents issued by the authorities. Our specialists prioritise real business situations, so we do not answer these questions individually — thank you for understanding.

Before you submit, please note

Free, no obligation: TRÍ TÍN answers free of charge and does not require you to use any service.
Response time: TRÍ TÍN replies by the email or phone number you provide. Our specialists set aside time each week for this section and usually reply within 7–10 days. When many situations arrive at once, or a situation needs further research, it may take longer; we will let you know. Thank you for your patience.
Nature of the answer: for reference only, based on the information you provide and the rules in force at the time of reply. It does not review specific files, figures or contracts and is not an official basis or opinion for a specific case. Every business is different — when specific files or figures need reviewing, TRÍ TÍN is ready to help.
Sensitive information: please do not send ID numbers, account numbers, passwords or documents containing sensitive information. If you need to share a file (for example Excel), mention it in your message and our specialist will explain how to send it.
Anonymous publication: situations that many businesses face may be written up as an article in our Knowledge section (with details removed, and only with your consent).
Use of information: the information you send is used only to reply and is not shared with anyone else.

Urgent matters (you have a notice or an appointment with the tax authority): please call or message us on Zalo instead of using the form.

Please note: TRÍ TÍN replies in Vietnamese only. Vietnamese tax and accounting rules are issued in Vietnamese, and translating legal and technical terms can shift their meaning — so we answer in the original language to keep every point exact. You may write your question in English; if your company has a Vietnamese-speaking colleague, please include their contact details.
