Discount first, then tax

In general the discount reduces the taxable amount, and VAT at 10% is charged on the reduced price. If a 15% discount is applied to a net price, the tax is calculated on the remaining 85%.

Worked example

Here is the calculation with sample figures. Change any number in the Vietnam Discount and VAT Calculator to run your own.

Does the order change the total?

Mathematically, applying a percentage discount and a percentage tax gives the same final price in either order. What changes is the tax amount you record and report, and that must reflect the price actually charged.

Vouchers and coupons

Store vouchers, manufacturer coupons and gift cards can each be treated differently. Some reduce the taxable price, others are treated as a form of payment. Check how each type is handled in Vietnam before you run a promotion.

Quick reference at 10%

Withholding
Tax deducted at source, by an employer or payer, before the money reaches you.
Reduced rate
A lower rate that applies to specific categories, often essentials such as food, medicine or books.
Deduction
An amount subtracted from taxable income. It saves tax equal to the deduction times your marginal rate.
