Under current tax law, taxpayers must fulfill many tax declaration and filing obligations for the 2025 tax period during Quarter I/2026. Tax authorities have identified three important deadlines that taxpayers should note.

The first key deadline is 20/1 for monthly tax declaration filings, specifically for the December 2025 tax period. This obligation typically applies to taxes such as value-added tax (VAT), personal income tax, and natural resource tax.

The second important deadline is 2/2 for quarterly tax declaration filings, applicable to the Quarter IV/2025 tax period. Common taxes requiring declaration include value-added tax and personal income tax.

The third critical deadline is 31/3/2026 for 2025 annual tax settlements. This includes corporate income tax, personal income tax, and annual financial statements. This date is crucial for tax authorities to determine taxpayers' final tax obligations for the preceding fiscal year.

According to the Tax Administration Law, taxpayers who pay taxes late will incur a late payment fee of 0,03% per day, calculated on the overdue tax amount.

Furthermore, late filing of tax declarations can also result in administrative penalties, depending on the severity of the violation. Specifically: delays of one to 30 days may lead to a warning or a fine of 2-5 million VND; delays of 31-90 days may incur a fine of 5-15 million VND; and delays exceeding 90 days could result in fines ranging from 15-25 million VND.

Tax authorities advise taxpayers to proactively review their records and accounting books, prepare declarations, and complete settlements on time to minimize potential fines and late payment charges.

Adhering to these tax declaration and payment deadlines not only helps businesses and business households mitigate legal risks but also contributes to greater transparency in financial management and compliance with tax laws.
