How Penalties Are Calculated

The exact penalty depends on:

  1. Duration of delay - Longer = higher penalty
  2. Nature of violation - First-time vs repeat
  3. Cooperation level - Voluntary disclosure helps
  4. Amount involved - Larger amounts = higher penalties

Mitigating Factors

Penalties may be reduced if:

  • First-time violation
  • Voluntary disclosure before audit
  • Cooperation with authorities
  • Reasonable cause documented

Late Payment Interest

Interest Rate

0.03% per day (approximately 10.95% per year) on unpaid tax.

Calculation

Interest = Tax Due × 0.03% × Number of Days Late

Example

Scenario:

  • Tax due: 20,000,000 VND
  • Days late: 60 days

Interest: 20,000,000 × 0.03% × 60 = 360,000 VND

When Interest Starts

Interest accrues from:

  • The original due date (for taxes not paid)
  • The date of assessment (for additional taxes)
