Frequently asked questions

It is 1,050 yuan including tax. How to calculate the untaxed amount?
In the general 5% mode of this tool, the tax amount for the total tax-included RMB 1,050 is 1,050 × 5 ÷ 105 = 50 yuan, and the untaxed sales volume is 1,050−50 = 1,000 yuan. The tool first rounds the input amount to whole yuan, and then rounds the tax amount to whole yuan. The sum of sales and tax amount is equal to the total amount.
1,000 yuan before tax, how much is it after adding tax?
In the general 5% mode of this tool, the tax amount of 1,000 yuan before tax is 1,000 × 5% = 50 yuan, and the total tax-included amount is 1,050 yuan. Select Untaxed Entry and fill in 1,000 to view the details and copy the results.
Why is there sometimes a difference of 1 yuan between the reverse calculations including tax and before tax?
Because both input and tax amounts are rounded to the nearest dollar. For example, 31 yuan including tax is divided into sales of 30 yuan and tax amount of 1 yuan; if an additional 30 yuan without tax is added to the tax, the tax amount of 1.5 yuan will be rounded to 2 yuan, and the total becomes 32 yuan. Please check the original transaction amount with the input mode. Do not assume that the reverse calculation will retain the original total amount.
Why does the total amount change when switching between tax-included or tax-exclusive mode?
Switching modes will be recalculated based on the current input value and will not automatically convert input fields. For example, the same number represents the total amount in tax-included mode, but represents the amount before tax in pre-tax mode.
Does choosing tax-free or zero-rated mean that the transaction qualifies?
No. The tool only performs calculations based on the mode you choose. The zero-rated and tax-free modes do not add tax, determine the eligibility of the transaction, and do not process declarations or special tax situations.
