Great easy and free to use tax calculator. I like the fact that you can just put in your tax code if you know it. Simplifies things. Also, it includes things like pension contributions and student loans. Think they are adding childcare vouchers now also. Handy little calculator which I go back to time and again. I see that moneysavingexpert now use the listentotaxman calculator on their site also so they must agree with me. Have emailed the people behind listentotaxman with suggestions for the calculator, such as the addition of childcare vouchers and found them to be really interested and helpful. I see they also have an i phone app available, which I will be sure to get, once I get an i phone!
