I need to change tax rate on my Victor1560-6

Please clarify the question. If you mean tax withholding rate, change the number of exemptions on your W-2. That won't change your tax liability at the end of the year, but will change your take home pay. If you mean actual tax rate, then you need to change the amount or source of your income, or change your tax deductions. Regarding source, I mean earned income vs investment income.

I'm in Australia and only going on the program manual for your area, it states that canadian tax is tax on tax? if this is true then you probably entered a code for add on or add in tax and thereby changed it all.

you need the following

tax table address
1 125
2 225
3 325
4 425

rounding off codes
rounding off to 2 decimal places is 50
rounding up to 2 decimal places is 90
cut off to 2 decimal places is 00

tax system code
tax table with out tax rate 01
tax table with tax rate and add on rate 02
add in tax rate 03
Canadian tax-on-tax rate 04

starting point
to get the starting point you multiply by 100 and subtract 1
eg 50 cents = 0.50 X 100 - 1 = 50 - 1 = 49
eg $4 = 4.00 x 100 -1 = 399

to program the tables go through these steps

go to program 3
tax table address eg 125
subtotal
tax rate
ca/amt tend
starting point eg 0.50 = 49
ca/amt tend
rounding eg 50
tax system eg 04
ca/amt tend
ca/amt tend

here you have 2 choices,

press ca/amt tend to go to the next tax table ie 225 and start over by entering the tax rate and go through the procedure again

or

press subtotal to finalise the tax table you are on

Hope this helps,

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!

Now what's the GT button for?

Printing models (except HR-8TE): 1. Have calculator in ?print? mode 2. Press [CA] 3. Hold [SET/%] key for about 3 seconds 4. Input the tax rate 5. Press [TAX+] 6. Press [SET/%]
