So just 5 easy steps to change the rate

1 press the AC button
2 hold down the SET /SET % / button for a few seconds
3 press the TAX + button
4 input the rate /in your case 6/
5 press SET button again
And you are done. You can also check it - press the Tax + button and the current tax rate will appear

Hope I helped !

In Quebce

We Tax 1 = 5% and Tax 2 7.5% ( Tax on the tax1)

Value 1.00

Tax 1 = 1.00 x 5% = 0.05

Suntotal= 1.00 + 0.05 = \$ 1.05

Tax2 = 1.05 x 7.5% = 0.79

Total = 1.00 + 0.05 + 0.079 = 1.13
