How to make a checkbox change value?
Question
So I am just wondering how would I change the value, whenever someone clicks on the checkbox. Basically the Total Land Transfer Tax (PLTT + TLTT) should become $0 . I have tired to do if statements with the checkbox but then the program does not working properly. Please I just need some advice should I do?

how were you doing your if statement?
Try this at the end of the calculations (but before changing textbox values)
if ($("#check1").is(":checked")) {
y3=0;
}

Use click event handler to handle checked/unchecked events and run the calculations inside as apt. jsFiddle link
$("#check1").click(function () {
if ($("#check1").prop("checked")) {
$("#final").val(0);
$("#toronto").val(0);
$("#provincal").val(0);
}
else{
calc();
}
});

you may try it .
$("checkbox#check1").on('click',function(){
if($(this).is(":checked")){
$("input#price").val(0);
}else{
calculate();
}
})
