Common Vietnam tax procedures

10 procedures that companies, individuals and household businesses in Vietnam often have to complete. Each procedure has its own page: the steps in order, the documents to prepare (tick and print), where to file and common mistakes. Filing itself is done on the official government channels.

TaxDatum is run by a private company, not the tax authority, and does not accept filings on behalf of the tax authority.

How to use a procedure page

Open the procedure and read Who needs to do this to make sure it is your case.
Tick each document you already have under What to prepare; use Print checklist if you need to bring it along or send it to someone helping you.
Work through the steps in order and tick the ones that are done. Ticks are stored only in the browser on this device.
When you reach the filing step, go to the official channel named under Where to file and sign in with your own account.

Messy files, several periods outstanding? A tax service team in our network can review and handle the work within an agreed scope.

Questions and answers

Does TaxDatum file returns or applications on behalf of a business?

No. Each procedure page only helps with preparation: the steps in order, the documents to have ready, where to file and common mistakes. Filing itself is done on the official channels - the e-tax system, the tax mobile app, the e-invoice portal or the National Business Registration Portal - using the taxpayer's own account.

Why do the procedure pages not give form numbers or processing times?

Because the circulars on tax registration and tax administration in force from 1 July 2026 may have changed forms and processing times. The pages only state milestones that are certain (such as the quarterly return deadline and the annual finalization deadline) and describe documents by their content; the exact form is taken from the system when filing.

Are the ticked steps saved?

Yes, but only in the browser on the device you are using; nothing is sent anywhere. If you change device or clear browser data the ticks are lost; to keep them, use "Print checklist" to print or save as PDF.

Reference content, written from general rules and possibly not yet updated for new documents; it does not give form numbers, penalty amounts or processing times. TaxDatum.com is run by a private company and is not a government portal. Before applying it to a real case, ask the managing tax office or a qualified professional.
