December 2018

This deadline is relevant for those individuals who complete a self assessment tax return online and who are employees. Where you have an underpayment you may request that HMRC collect the tax outstanding by making an adjustment to your tax code for the year 2019/20.

If we are already dealing with this matter on your behalf you need take no action.
