Phase 1\/2026: Focus on settling accounts for the previous year.<\/b><\/h3>\n

January and March are the two busiest periods. January 30, 2026 is the deadline for filing corporate income tax returns for the fourth quarter of 2025. This is when businesses must balance the tax amounts already paid in the previous three quarters to ensure they do not violate Rule 80%.<\/span><\/p>\n

By March 31, 2026, businesses must submit their financial statements and tax return for 2025. This deadline cannot be extended except in special circumstances. If the final tax amount is higher than the amount already paid in advance, the difference must be settled immediately on this day to meet the deadline for corporate income tax payment in 2026.<\/span><\/p>\n

Period Q2\/2026: Initial tax obligations<\/b><\/h3>\n

Due to the extended holiday period, the deadline for filing corporate income tax returns for the first quarter of 2026 usually falls in early May. Accountants need to prepare revenue and expense data for the first three months of the year to determine the provisional tax amount. Accurately forecasting business results helps businesses be more proactive in meeting the 2026 corporate income tax deadline.<\/span><\/p>\n

Phase 3 and 4\/2026: Acceleration and Review<\/b><\/h3>\n

In the third quarter, July 30, 2026 is the deadline for filing corporate income tax returns for the second quarter. By the end of October, businesses will file for the third quarter. This is a crucial period for reviewing all reasonable and legitimate expenses in preparation for the next year's tax settlement.<\/span><\/p>\n

Risks and penalties for violating the 2026 corporate income tax payment deadline.<\/b><\/h2>\n

Missing the 2026 corporate income tax deadline will have consequences for businesses that extend beyond just money; it will also affect their tax credit rating.<\/span><\/p>\n

Penalties for late filing of tax returns<\/b><\/h3>\n

According to Decree 125\/2020\/ND-CP, the penalty for late filing of tax returns can range from 2 million VND to 25 million VND, depending on the length of the delay. This is separate from the penalty for late payment of corporate income tax by the 2026 deadline.<\/span><\/p>\n

How to calculate late payment penalties for taxes<\/b><\/h3>\n\n\n\n
\n

Late payment penalty = (Amount of tax overdue) x 0.03% x (Number of days overdue)<\/span><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
