Setting the tax rate on your Casio calculator is a one-time task that saves you from doing manual math every time you need to calculate a grand total or strip tax away from a price. Whether you are using a standard desk model (like the MS-80B) or a heavy-duty printing calculator, the process is nearly identical across most Casio "Tax & Exchange" series.

Here is a comprehensive guide on how to program your tax rate and use the tax functions effectively. Phase 1: Checking the Current Tax Rate

Before you change anything, it’s helpful to see what rate is currently stored in the memory. Press the [AC] key.

Press and hold the [%] (SET) key for about two seconds until "SET" appears on the screen.

Press the [TAX+] key. The screen will display the current rate (e.g., "0" or "5"). Phase 2: Setting a New Tax Rate Follow these steps to input your local sales tax or VAT: Clear the memory: Press the [AC] key.

Enter Set Mode: Press and hold the [%] (SET) key until "SET" appears on the display.

Initiate Tax Setting: Press the [TAX+] key. You should now see "TAX" and "%" blinking on the display, and the screen should show "0".

Enter the Rate: Type in your tax rate. For example, if your tax is 7.5%, simply type 7.5. (Do not press the % key again).

Save the Rate: Press the [%] (SET) key one last time. The number you entered is now stored.

Note: If you have a printing calculator (DR or HR series), make sure the selector switch is set to "PRINT" or "ITEM" to see the "SET" indicator clearly. Phase 3: How to Use the Tax Buttons

Once your rate is programmed, calculating totals becomes a two-click process. To Add Tax to a Price (Price + Tax) If you have a net price of $100 and want to find the total: Type 100 Press [TAX+] The screen will show the Total Amount ($107.50). Press [TAX+] again to see the Tax Amount only ($7.50). To Remove Tax from a Price (Price - Tax)

If you have a total of $107.50 and want to find the original price before tax: Type 107.50 Press [TAX-] The screen will show the Pre-Tax Price ($100).

Press [TAX-] again to see the Tax Amount that was included ($7.50). Troubleshooting Common Issues

1. The "SET" label isn't appearing.On some older Casio models, you must press [AC] twice before holding the [%] key. If your calculator does not have a "SET" label above the percentage key, look for a small hole on the back or side of the calculator labeled "SET" and press it with a paperclip.

2. The rate keeps resetting to zero.If your calculator is "Dual Power" (Solar + Battery), a dead internal battery can cause the memory to wipe whenever the calculator is in a dark room. If your tax rate won't stay saved, it’s likely time to replace the LR44 or CR2032 battery inside.

3. Decimal placement issues.If you enter "7" and the calculator shows "0.07," check your decimal selector switch (the slider at the top). For tax settings, it is usually best to keep the slider on "F" (Floating) or "2". Quick Summary for Pros:

[AC] → Hold [%] (SET) → [TAX+] → [Enter Number] → [%] (SET)

By mastering these few keystrokes, you can fly through invoices and expense reports without ever needing to look up a percentage table again.

Here’s a useful, practical story that walks through setting a tax rate on a standard Casio calculator (like the popular Casio HL-815L, MS-80B, or similar “tax” models).

Title: Mr. Ito’s Bakery and the 10% Tamago Tax

Mr. Ito ran a small bakery in Osaka. Every day, customers bought his famous tamago (egg) bread. But Mr. Ito had a problem: Japan’s consumption tax had just changed to 10%, and he was tired of fumbling with his phone’s calculator. “I need the tax added instantly,” he sighed.

His old Casio desktop calculator had two mysterious keys: TAX+ and TAX−. He’d never used them. “Time to learn,” he said.

Changing the rate is the same as setting it. Just repeat the setup steps with the new percentage.

On the left side or top of your Casio printing calculator, you will see a small physical switch. It usually has three positions: OFF, ON, and TAX SET (sometimes labeled RATE SET or PRINT/SET). Slide it to the TAX SET position.

Note: On some older models, you may need to press a 'SET' button while turning the calculator on.

Step 2: Enter your tax rate.
Using the numeric keypad, type your desired tax rate as a whole number. For example:

Step 3: Store the tax rate.
Press the TAX+ button (or sometimes labeled % or RATE). You will see "TAX %" appear on the display, and the number you entered will flash or stay steady.

Step 4: Lock and verify.
Slide the mode switch back from TAX SET to ON (or PRINT). Now, press the TAX+ button once without entering any number. The display should show your stored tax rate. For a printing model, it will print something like “TAX % 8.5”.

Once upon a time, in a small stationery shop, there was an accountant named Arthur. Arthur had a pile of receipts a foot high and a brand-new Casio calculator on his desk.

Arthur had a problem. His country’s sales tax was 8%. He had to calculate the final price for hundreds of items. He found himself typing the same thing over and over:

Arthur sighed. "There has to be a better way." He looked at his calculator and noticed three mysterious buttons he had never touched: TAX+, TAX-, and a small, recessed button labeled SET (or sometimes RATE).

Arthur decided to solve the mystery.
