Formula
Duty = Customs Value × Duty Rate ÷ 100 | VAT/GST = (Customs Value + Duty) × Tax Rate ÷ 100
In most countries, VAT or GST on imported goods is applied to the duty-inclusive value — meaning tax is calculated on the customs value plus any import duty. This is sometimes called a 'tax on a tax' effect and means the combined tax burden is higher than simply adding the duty rate and VAT rate percentages. The effective tax rate shows total taxes as a percentage of the original customs value.
Worked Example
Import to UK: Customs value USD 10,000 · Duty rate 5% · UK VAT 20%:
Duty = USD 10,000 × 5% = USD 500
VAT base = USD 10,000 + USD 500 = USD 10,500
VAT = USD 10,500 × 20% = USD 2,100
Total taxes = USD 500 + USD 2,100 = USD 2,600
Effective tax rate = USD 2,600 ÷ USD 10,000 = 26.0%
Note that the effective rate of 26% is higher than simply adding 5% + 20% = 25%. The difference arises because VAT is applied on the duty-inclusive base. For VAT-registered importers who reclaim VAT, the effective cash cost may be only the duty (5%) plus the time-cost of the VAT cash flow.
