Tax declaration is a tax management method where business households calculate the amount of tax to be paid themselves, prepare declarations and submit them to tax authorities monthly or quarterly. The things to do are actually very simple. Business households only need to record revenue and expenses in the period, issue invoices when selling goods or providing services, prepare declarations based on actual revenue and pay taxes on time. Declaration can be done online, not requiring going to the tax authority. These steps help both tax authorities and business households have accurate, transparent and easy-to-manage data.
According to the policy roadmap, from January 1, 2026, tax declaration becomes mandatory for business households. However, this does not mean increasing the burden of procedures. In fact, with MISA eShop, the entire process of selling goods - issuing invoices - declaring and paying taxes is integrated into a single application, helping business households easily access and comply with regulations.

MISA eShop software allows automatic revenue recording immediately when selling goods, issuing electronic invoices with just a few operations on a phone or computer. Sales data and invoices are automatically compiled, from which the software supports preparing monthly or quarterly tax returns, minimizing errors compared to manual methods.

No need for expensive computers or phones, with just a smartphone, business households can self-declare, pay taxes and issue invoices without worrying about the burden of investment costs or hiring accounting services.
