UK Tax Calculator

This is a question for you Brits out there who know the UK tax system, as I don´t know much about it myself.
Here is a tax calculator I found online: http://www.listentotaxman.com/

What I am specifically wondering about is whether this calculator would give a realistic/credible estimate of what (at least a UK citizen) would have to pay in tax, in total, during the course of a year. The way I would fill it out is choosing the year 2007, not checking any of the boxes for married etc, no student loan repayment, choosing the under 65 age range, no other allowances/deductions and no tax code simply because I don´t know what if anything to type in those categories! (and lastly, typing in gross income per year).

Does the calculator have any "flaws" in terms of not calculating/accounting for major numbers that would affect the total amount of tax that a citizen would pay?
Would the average person type in anything in the "other allowances/deductions" and "tax code" boxes? What do they mean and do they have a profound impact upon the total tax you would pay?

And finally I wonder about the following issue: Would an EEA citizen (who does not have a UK passport) pay different taxes if working in the UK than would a "native" UK passport citizen?

Thanks a lot in advance to you UK people out there!

Why don't you just ask the question you really want an answer to?

For example: I live in Poland and have been offered a job in the UK that pays X. I would like to know how the cost of living compares between the two countries in order to determine whether it is a good offer or not.

Figuring out what tax you would pay on a given income tells you nothing other than what tax you would pay. The question you really want an answer to probably requires other factors be taken into consideration.

Nope the question I really want an answer to concerns the tax system of the UK, hence my query about the tax calculator (I already have an idea of the general living conditions in London at least).

Its pretty accurate, I've used it before and it comes up about right.

Also yes you'd pay the same taxes as a UK native.

I was on an Australian passport and I paid the same amount of tax as everyone else. It's pretty easy to work out the tax you have to pay, and if you are in any doubt simply contact the HMRC - I did and they were very helpful. Besides which, you get a letter from the HMRC every year telling you what tax rate I would be getting charged at and this letter had all the information needed to calculate how much tax I had to pay. It's not rocket science ...
