Who is the "tax man" and how do I pay Tax?

[Eleathegreat]

first of all are you empolyed or self empolyed?

what job are you doing?

does your empolyer pay tax and NI for you?

if your using your car to drive to work does the company pay you anything for mileage?, because if you goto your local tax office you can claim mileage from them(the tax office)?

-employed.
-Im in the telecom sector.
-my employer pays the tax/NI automatically every month (from my salary of course)
-the company doesnt pay me anything for mileage.

I think the best way for me then is to go to the local tax office ... is there a deadline for that (tax year 2009-2010)? I just dont have the time to do all these... that's why im thinking if it's worth having a tax advisor who can do all this bits and pieces.

I also tried to go to our HR and she said "you have to do that yourself dear."
