From CASIO FAQS:

Non-printing models (also applies to HR-8TE printing calculator):

1. Press [AC]
2. Hold [SET/%] key for about 2 seconds
3. Press [TAX+]
4. Input the tax rate
5. Press [SET/%]

1. Press the AC button (bottom right of the calculator)
2. Press the % button (top line of calculator) and hold for around 2 seconds until the word "SET" appear on the display.
3. Press the TAX+ button (top right of calculator) it will then display what ever setting is current for Tax. Most deafults are set at 5%. Simply put in the % you want i.e. 17.5% for UK Vat etc...
4. Press the AC button (bottom right of the calculator) again and the job is completed
5. Test by putting in100 and then pressing the TAX+ button (top right of the calculator).
