Tax in a Double Entry Bookkeeping Sheet?

Hi,
I'm totally new to running business and doing my own bookkeeping so bare with me. I've looked at a few tutorials on double entry bookkeeping.
Most of them are kind enough to simplify it to the point that even I can understand it. But they simplify it so much that it misses some things. Like Tax. I am struggling to figure out where tax goes in a double entry style bookkeeping sheet.
So please suggest me with your ideas.
Thanks in Advance.
