New penalties were introduced on 6 April 2011 for Self Assessment customers who fail to meet their tax return and payment deadlines. There may still be some cases where the old penalty rules apply - this is a brief reminder of what these are.
If you were asked to complete a tax return for any year up to 2009-10 and you still haven't sent it back, the old penalty rules will apply.
You'll be charged an automatic £100 penalty.
If it's a Partnership Tax Return there's a £100 penalty for each partner.
If it's a Trust and Estate Tax Return there's a £100 charge to the trust or estate.
If you owe tax for any year up to 2009-10, the old rules will apply. You will continue to be charged interest and possibly one or two five per cent additional charges, called surcharges, on top of the amount you still owe.
