Taxation of partnership firms

I with my friend did a parnership deed on August 2010 and then he went on doing a job and I continued the business ( website development / software development ).

Also we had a PAN card made in name of the Firm and Now we need to open a bank account in name of our Firm, but we have never paid any taxes nor service nor personal. But now we want to start a fresh and we don't know anything about taxation and it's legal aspects.

So what should we do now as such everything becomes legitmate ?

Please guide.
