Are you one of the million?

One million people have missed the deadline to complete their self assessment tax return. If you have completed a self assessment in the past, but you no longer have different income streams, you must still compete a return, unless advised differently. Those now late will be charged a £100 late return notice, even if there is no tax to pay. This can only be overturned, if you have a genuine excuse. Don’t leave any later, otherwise that penalty will keep rising!
