How do I program tax rate into my calculator? 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/%]

On your Sharp press
CA
C.CE
C.CE
RATE SET(+TAX Key)
175(No decimals for they are not taken into consideration)
RATE SET(+TAX Key)

To check if all went well press
CA
C.CE
C.CE
RATE RECALL(-TAX Key)
It should read your tax rate.

I had the same problem and finally figured it out. Here's what you do:

Press C-CE twice
Press +TAX (Rate set)
Key in your new tax rate as an integer (e.g. 5)
Press +Tax (Rate set) again
Press C-CE

Then you're ready to calculate with the new rate!
