Vietnam Small Business Tax Guide: From VAT to Filing Deadlines

Key insight

"Tax stops being scary once you know the forms—then it becomes a pricing tool."

"Insights from real conversations and real problems"

Part 1: VAT - Understanding It to Price Correctly

What is VAT?

Value-added tax (VAT) is not money the government takes extra from sellers, but a mechanism to encourage or discourage certain product groups. Each country applies different rates: priority items may be reduced or exempted, while items to be restricted face higher taxes.

Simple Example with a Water Bottle

Suppose you sell a bottle of water for 10,000 VND and VAT for this item is 10%.

  • Customer pays: 11,000 VND.
  • You only keep 10,000 VND – actual sales revenue.
  • The remaining 1,000 VND is collected on behalf of the state, must be remitted on time.

Don't Forget Corporate Income Tax

Besides VAT, businesses must also pay corporate income tax (CIT) calculated on profit. For very small businesses, tax rates are often preferential to encourage startups.

Part 2: Tax Filing Schedule - No More Missing Deadlines

Why Track Your Tax Calendar?

When Tea first opened her company, she wished someone had given her a simple sheet listing what to file each quarter. Information was everywhere, but overwhelming—easy to miss deadlines. Below is a tidy version for small businesses.

For Companies with VAT

  • Quarterly: 1 VAT return + 1 personal income tax (PIT) return.
  • Year-end: PIT finalization, CIT finalization, and full financial statements.

For Companies Without VAT

  • Quarterly: only PIT return.
  • Year-end: PIT finalization and CIT finalization.

Practical Tips

  1. Set reminders 1-2 weeks before deadline
  2. Maintain simple books to track revenue and expenses
  3. Consult an accountant if revenue grows quickly
  4. Store supporting documents fully for reconciliation when needed

Understanding taxes well not only helps you comply with the law but also price products accurately, predict cash flow, and plan business more sustainably.

What do you think?

This article might've started as a scribble on the back of a receipt during a bus ride, a spark of something real after a conversation over a pint of Leffe, or notes from a Sunday afternoon client call that left me buzzing with ideas. However it came to be, I hope it found you at just the right moment.

If it stirred something in you, or if you're just curious about anything from automating the boring bits of your business to capturing your quiet magic in a coffee shop shoot — shall we pencil something into the diary?

I'd love to be on the other end of the conversation.
