no exception to this trend. However, large business households are currently facing
significant challenges in the digital economy stemming from limitations in capital,
capacity, technology, and especially compliance with new tax regulations. With many
new regulations related to revenue management and payment accounts for household
businesses coming into effect from 2026, and mandatory digital financial services for
large household businesses such as online tax payment, tax deadline reminders,
electronic invoices, electronic statements and digital signatures, and a self-declaration
mechanism, tax accounting at large household businesses becomes increasingly
important. It needs to be fully implemented and coordinated with tax authorities, the
banking system, and other public entities. Effective tax accounting at household
businesses will play a crucial role in supporting them to standardize their financial
operations, improve operational efficiency, and comply with tax laws in the digital
