The Revenue a while ago stopped sending us copies of taxpayer tax codes. It did this to cut costs.
This means that we do not know if your tax code that is operated against your salary is correct. You may be paying too much or too little tax.
To avoid paying the wrong amount of tax, please send us your tax code for checking, or drop us an email if the code was issued after 11 October 2011.
From this date, HMRC includes copies of the tax code on our agent section of its website.
So if you tell us you have been issued with a tax code, we can log in and check it for you.
