Details of penalties for late submission of personal income tax returns.

Late submission of personal income tax returns is subject to administrative penalties as stipulated in Article 13. Decree 125/2020/ND-CP. The penalties vary depending on the number of days overdue, ranging from a warning to a fine of up to 25 million VND.
Below is a detailed summary of penalties for individuals or organizations who are late in submitting their personal income tax returns, for your easy reference:
| Late submission period | Forms of punishment | Fine amount (VND) |
| From 1 to 5 days (with mitigating circumstances) | Warning | 0 |
| From 1 to 30 days | Fine | 2.000.000 – 5.000.000 |
| From 31 to 60 days | Fine | 5.000.000 – 8.000.000 |
| From 61 to 90 days | Fine | 8.000.000 – 15.000.000 |

Cases where penalties for late filing of personal income tax returns are waived.
Not all late filings result in penalties. The tax authorities clearly state that individuals who have overpaid taxes and request a refund or tax offset in the next period but file their tax returns late will not be subject to administrative penalties. This is an important point to alleviate concerns for those entitled to a refund regarding late filing of their personal income tax returns.
However, even without a fine, late filing of personal income tax returns in this case still delays the tax refund process, affecting the individual's cash flow. Therefore, filing on time remains the best option.
How to calculate late payment penalties for taxes and fines.
Besides administrative fines, late payment of personal income tax returns also leads to consequences such as "interest" on delayed payments to the state budget. According to Clause 2, Article 59 of the 2019 Tax Administration Law, late payment interest is calculated using the following formula:
|
Late payment penalty = Amount of tax overdue x 0.03% x Number of days overdue |
Prolonged delays in filing personal income tax returns will significantly increase this figure over time. Furthermore, if taxpayers receive a penalty notice but fail to pay the penalty on time, the late payment penalty will be 0.051 TP3T/day on the overdue penalty amount.
Therefore, as soon as taxpayers discover they have been late in filing their personal income tax return, they should proactively submit the documents and immediately pay the outstanding tax amount plus any calculated late payment penalties to minimize the risk of aggravating circumstances from the tax authorities.
Things to note to avoid the risk of late filing of personal income tax returns.
