    What is "underpayment restriction"? 28th Jan 12 at 6:47 PM
    Hi and thanks for taking the time to read my post and hopefully help!

    Can some one explain "underpayment restriction" please. I'm cofused about the word "restriction" and even more confused with HMRC's explanation.

    Is it simply underpayment of tax?

    This is why I ask:
    I earned some money from another source other than my main employer. Having declared the earnings, last year the HMRC changed my tax code to collect the tax owed on this amount. Fine.
    This year I received an even lower tax code stating I may remember I owed them money....

    BUT surely they altered my tax code to collect the money last year, so why are this saying I still owed them money?

    "underpayment restriction -£1900"

    Thank you in advance for your replies.
    Can anyone explain to me how to put a signature here?
