[UPDATED] Did you know that you get an automatic £100 minimum penalty if you file your Self Assessment tax return (or pay any tax owed) even one day late? After 3 months you can add £10 per day extra to that fine (up to 90 days/£900 max) and after 6 months it gets significantly worse. And remember that you need to file your return on time even if you don’t owe any tax, or if you have already paid it! Latest indications are that there are also no warnings given by HMRC. See the table below for the detail.
So our message is simple: don’t file late, and don’t pay late! Taxfile are here to help you, of course. We know Self Assessment Tax Returns back to front and we can help you file accurately, and on time.
