If you have been sent a Tax Calculation, or P800, showing you have previously underpaid tax, in certain circumstances HM Revenue & Customs (HMRC) may agree not to collect it using 'Extra Statutory Concession A19' (ESC A19).
ESC A19 only applies to people who owe Income Tax or Capital Gains Tax. It does not apply to other taxes.
This guide explains the rules for ESC A19 and how you can ask HMRC to apply it.
On this page:
HMRC will only agree not to collect an underpayment if the tax is unpaid and the following circumstances apply:
This means, for example, if you receive a Tax Calculation, or P800, in the 2013-2014 tax year showing that you have underpaid tax in the previous tax year (2012-2013) then ESC A19 will not apply.
A tax year runs from 6 April in one year to 5 April in the following year.
However, in exceptional circumstances, HMRC may consider cases where your underpayment is notified within 12 months of the tax year in which the information was received, subject to certain conditions (see Exceptional Circumstances below).
Information that HMRC uses to change your tax code so that you pay the right amount of tax includes:
This is not a full list. HMRC treats each request on its own circumstances.
This information can come from a variety of sources - for example a letter from you or your agent, or a notification from your employer or the Department for Work and Pensions (DWP).
If HMRC did not receive any information to use or to act upon, ESC A19 cannot apply.
HMRC can only apply ESC A19 if it hasn't used information that would affect your tax, within 12 months from the end of the tax year it receives the information.
For example: on 1 August 2012 HMRC received information about the start of a new pension in tax year 2011-12. (tax year ending 5 April 2012). For the purposes of the concession HMRC should have issued a tax calculation reflecting this information before 5 April 2014. Otherwise, ESC A19 does not apply, unless there are Exceptional Circumstances.
If the tax repayment you get from HMRC is more than it should have been they can ask you to pay back the extra money. But they must contact you to ask for the extra tax back within 12 months of the end of the tax year.
If HMRC did not receive any information they can't accept a request for ESC.A19.
In exceptional circumstances HMRC can consider a request for ESC A19 if it told you about tax you owe less than 12 months after the end of the tax year in which it received information that changed the amount of tax due. Both of the following must apply:
If these conditions are not met, then ESC A19 cannot be considered.
HMRC also needs to consider whether it was reasonable for you to believe (before you received your tax calculation) that your tax affairs were in order.
It may take into account relevant details about your circumstances such as notes of conversations with HMRC officials and customer records.
It will also consider any evidence offered by you, or your agent, about your personal circumstances explaining why you believed that your tax affairs were in order, or whether you were able to manage your tax affairs at the time.
ESC A19 does not apply where you have paid the tax owed. But if you think this concession applies to you should contact HMRC before you pay the underpaid tax.
You will need to tell HMRC:
HMRC will consider your request but may need to check some details with you before giving you a decision.
There is no right of appeal if your ESC A19 request is refused, but you can ask for another HMRC officer to review the decision.
If you still believe that you should not have to pay the tax after a second review decision has been made, please read 'How to Complain to HMRC' to decide if your case has not been dealt with properly.
