    I pressed the CA button twice. Then pushed the %/set key until the 0 dissappeared and reappeared. then typed in the new tax rate and the percent key and the tax+ key.

    Great - it works for HR100TE too.
    reminder that to hold the tax rate after you turn off the Casio, be sure before setting you put the calculator in the print position!

How do i change the sales tax on se-s700?

Hello, Ron -

I hope you have the owner's manual for your Casio SE-S700 Electronic Cash Register. If so, the instructions for setting the sales tax start on page E-11.

If you don't have the manual, you can find a copy to download, save, and print here:
It is a PDF document, so you will need Adobe Reader (free.)

Look on page E-11 for the instructions to set the tax table.

It depends upon a few things. Does your country use add on (tax added at the end) or add in (tax included in price). Which tax number is the machine using (1 to 4) for VAT?

Make sure you have flipped the switch all the way towards you to program.

Press 1 for tax rate #1. Press Tax Shift. Then put in your rate with 4 digits where 8% is 8000. Press Total.

If you want a department key to be taxable, press 001, press check, type in the price you want that department to be, and then press the department key.

If you want to make it not taxable, press 000, press check, type in the price, then press the department key.
