I am an Indian and my company is planning to send me UK on WP. I want to know that how tax workings are being done there and what type of benefit or obligation would be there.

I will be paid some payment for which bills has to be produced and some part would be without bills.

In India amount paid against bills are non taxable and other payment are taxable based on some condition.

So can some one help me to understand the UK tax law so that I can calculate my tax in UK

This forum is about the U.S. taxes.

I fail to understand why you disagree with my statement.
