Depending on the business model, periodic tax filings typically include:
- Value Added Tax Declaration Form (Form 01/GTGT or 04/GTGT).
- Personal income tax return form for deductions from salaries and wages.

- Report on invoice usage (if required).

| 31 to 60 days | 5,000,000 to 8,000,000 VND |

| If the period exceeds 90 days, tax payable will arise. | 15,000,000 to 25,000,000 VND |
Important note: the fine for individuals and household businesses is half the amount above (Clause 5, Article 5 of the same Decree).
