This article will walk you through the necessary steps to transition to and register for these cash register-generated invoices starting June 1, 2025, along with some important things to keep in mind.
This article provides a how-to guide for business households on switching over to and registering for the use of invoices produced by cash registers, starting June 1, 2025, along with some important points to keep in mind.
1.1. Four Key Steps for Businesses Registering for Cash Register-Generated Invoices
After transitioning and registering to use invoices generated from your cash register, business households need to take care of four main tasks:
Get Your Technical Gear Ready
To use invoices generated from cash registers, you'll need a device connected to the internet. This could be:
- A smartphone or tablet
- A desktop computer
- A POS machine
- A dedicated cash register system.
If business households or individual businesses qualify for using electronic invoices directly from their cash registers but lack the necessary IT infrastructure and solutions, the tax authority should provide support and guidance to help them transition to this new system.
Sign up to use invoices that are produced by cash registers.
The last day to register is May 30, 2025.

Registering a change in how taxes are calculated
Because of this, if you want to change your tax calculation method, you must register by May 30, 2025, at the latest.
The registration form you'll need is Form 08-MST, as outlined in Circular 86/2024/TT-BTC, which is for switching from the lump-sum tax method to the declaration method.
* A lump-sum tax is a special way of taxation, based on a fixed amount, rather than on the real circumstance of the taxed entity.
Tax Declaration Information
Which form to use: You'll need to fill out Form 01/CNKD, as outlined in Circular 40/2021/TT-BTC, for your tax declaration.
When to submit your declaration:
- Monthly declarations: Make sure to submit your monthly tax declaration by the 20th of the month immediately following the month when the tax was incurred.
- Quarterly declarations: For quarterly declarations, the deadline is the last day of the first month after the end of the quarter in which the tax liability arose. The tax authorities actually recommend this option.
