The LS-100TS has tax keys. I suspect (for I cannot have access to a manual, just the online brochure by Canon) that you have to switch left to right or up-down one of the tax keys then you enter the tax percentage. and toggle back into position.

Hide All
Percentages are calculated by using the following equation:
amount/total = percentage
Where percentage is in decimal format.
What do you want to do?

### Tax-

The Tax- function allows you to take the total cost (sub-total + tax) and it will subtract the tax and leave you with the sub-total (before tax).

Example:

If the item you have is \$5 and the tax is set to 5%... when you use the Tax+ key it'll give you 5.25.

Conversely, when you enter 5.25 and press the Tax- key and it will give you the base price of \$5.

So the Tax- key removes the tax from the total amount.
It doesn't remove the percentage OF the total amount.
