How to Set the Tax Rate on a Casio Calculator

Follow these steps to program the tax rate so the calculator can quickly add or remove tax.

1. Turn the calculator on.
2. Enter the desired tax rate as a number (e.g., for 8.25% type 8.25).
3. Press the [SHIFT] key, then press [TAX+] (often labeled with % or TAX+ above a key).
   • This stores the entered percentage as the tax rate.
4. To add tax to a price, enter the price and press [TAX+].
5. To remove tax (calculate pre-tax price), enter the taxed price and press [TAX-].

Notes:

• Some Casio models label the tax function as [GT/TAX], [TAX+]/[TAX-], or use a dedicated [%TAX] key—look just above the keys for the TAX+ and TAX- labels.
• If you need to change the rate, simply repeat steps 2–3 with the new percentage.

Example:

• Set 8.25%: 8.25 → [SHIFT] → [TAX+]
• Add tax to 100.00: 100 → [TAX+] → displays 108.25
• Remove tax from 108.25: 108.25 → [TAX-] → displays 100.00

If you tell me your Casio model (e.g., fx-991ES, MS-80B), I can give exact key labels.

Before I tell you the story, there is one very important detail you must know: Not all Casio calculators can store a tax rate.

If your calculator has a button labeled TAX+ or TAX-, you are in luck. If it does not have these buttons, it cannot be programmed.

Here is the story of how the "Tax Button" came to life.

The happy ending

No more phone fumbling. Mr. Ito saved 30 seconds per transaction. His customers got faster service, and he never miscalculated the new 10% “Tamago Tax” again.

Quick reference (generic Casio tax-set sequence):

1. Hold AC (or SET, or RATE SET) until “SET” or “TAX %” appears.
2. Type the tax rate (e.g., 1 0 for 10%).
3. Press TAX+ (to store).
4. Press TAX RATE or AC to exit.
5. Test: Enter 100, press TAX+ → should show 110 (for 10% tax).

Note: Different Casio models vary slightly. If the above doesn’t work, look for a RATE or SETUP key, and check the manual. The key principle: Enter rate → Store with TAX+ is the most common pattern.

Now you – like Mr. Ito – can set a tax rate on a Casio calculator in under 10 seconds. 🧮
