Converted amount
10,000TWD
An inclusive price already contains tax. Recovering the before-tax price requires division, not simply subtracting the same percentage.
Amount before tax10,000 TWD
Tax500 TWD
Amount including tax10,500 TWD
Converts amounts using the tax rate you entered. Does not determine tax eligibility or applicability.
Method and scope
Tax-inclusive price equals pre-tax price times (1 plus the rate). To remove included tax, divide by that factor rather than subtracting the same percentage.
The tax amount is the difference between the two prices. All amounts retain the currency entered; no exchange conversion occurs.
The rate is your input, not a determination of Taiwan tax eligibility or exemption. Invoice rounding and the actual tax treatment must be checked separately.

What to enter

How the calculation works
Tax-inclusive price equals pre-tax price times (1 plus the rate). To remove included tax, divide by that factor rather than subtracting the same percentage.
Worked example
At 5%, a TWD 1,000 pre-tax amount becomes TWD 1,050 including tax. Entering 1,050 as tax-inclusive gives TWD 1,000 before tax.
Understanding the answer
The tax amount is the difference between the two prices. All amounts retain the currency entered; no exchange conversion occurs.
