This is the general edition of this guide for Vietnam. It explains how the Tax code (MST), VAT and annual filing work and names General Department of Taxation as the place to confirm thresholds and dates. Country-specific figures are added as each edition is reviewed.
The rate
The standard rate in Vietnam is 10%. Some goods and services carry reduced or zero rates and others are exempt. The difference matters: zero-rated sales still let you reclaim the tax on your purchases, exempt sales do not.
A temporary 8% rate applies to many goods and services under stimulus decrees.
Who must register
Registration becomes compulsory once taxable turnover passes the threshold General Department of Taxation sets, measured over a rolling period. Below it, registration is usually voluntary, which makes sense if your customers are registered businesses that can reclaim what you charge.
How to register
Register with General Department of Taxation using your Tax code (MST). Once registered you receive a VAT registration number or certificate, and from that date you must charge VAT on taxable sales, issue compliant invoices and file returns even when nothing is due.
Charging VAT on an invoice
Show the net amount, the VAT rate, the VAT amount and the gross total, with your registration number in the header. Prices quoted to consumers should include VAT; prices quoted to businesses usually exclude it and say so. The Vietnam calculator adds or removes VAT and shows the arithmetic.
Filing and paying
Returns are periodic, most often monthly or quarterly, and report the VAT you charged less the VAT you paid on purchases. The difference is paid to General Department of Taxation by the return deadline; a repayment is claimed when purchases exceed sales.
Penalties for getting it wrong
Late registration, late returns and late payment each attract penalties and interest with General Department of Taxation. Charging VAT while unregistered is an offence in most countries. If you missed the threshold, register now and declare the back period.
Questions people ask
How do I add VAT to a price?
Multiply the net price by 1.1. A ₫100 sale at 10% carries ₫10 of VAT and totals ₫110.
How do I remove VAT from a total?
Divide the gross by 1.1 to get the net, then subtract to find the tax. Dividing, not taking a percentage off, is the step people get wrong.
Should I register voluntarily?
If most of your customers are registered businesses, yes: they reclaim what you charge and you reclaim what you pay. If your customers are consumers, registration raises your prices by the tax rate or cuts your margin.
What if I am not registered?
Do not charge VAT and do not show a VAT line. State on the invoice that no VAT was charged. The generator prints that line when the toggle is off.
