1. Introduction
About this Call for Evidence
1.1 The government is keen to ensure that the process to amend a tax return is
simple and transparent for taxpayers to use.
1.2 The government recognises that tax records will increasingly be held and
submitted digitally. With the HM Revenue and Customs (HMRC) digital agenda
there is an opportunity to modernise the process and create a better taxpayer
experience.
1.3 There are a number of different methods of making amendments to returns,
which vary according to tax, value, accounting period and turnover. For
example, the processes for amending Income Tax Self-Assessment (ITSA),
Corporation Tax Self-Assessment (CTSA) and VAT returns differ and are not
consistent across the taxes or aligned with the digital future of tax
administration.
1.4 This Call for Evidence sets out the current way in which amendments to returns
are made and we are keen to gather evidence on the issues taxpayers face
when making an amendment. We also want to understand what the experience
is like for a taxpayer for each tax type, and understand whether alignment of
amendment methods across the taxes can work well. Further information to
assist HMRC in fully understanding the amendments process experience would
be welcome.
1.5 Following responses to this Call for Evidence we will seek to develop policy
solutions to any issues highlighted in the amendments to returns process.
1.6 Chapter two sets out what we mean by amendments to returns and the
differing existing processes across the tax system. Chapter three sets out the
policy work HMRC has already undertaken to review amendments and it also
explores the scope of the policy solutions given the future vision of tax
administration. We also ask a series of direct questions in the main chapters
and would welcome your responses to these.
1.7 We are keen to hear from taxpayers (both businesses and individuals), agents,
and representative bodies with views on amendments to returns, to help us
address any inadequacies and to ensure we introduce consistent administration
policies.

2. Current position on tax returns
HMRC’s policy on amending tax returns
2.1 An amendment is any change made by a taxpayer to a submitted return. It
forms an important part of HMRC’s tax administration framework and ensures
that both HMRC and its customers can exercise their right to correct, adjust or
amend a filed return. The process in making an amendment varies according to
tax type and in this chapter we will set out the existing processes for ITSA,
CTSA and VAT.
2.2 Where a taxpayer wants to make a change to a tax return, in some instances it
is possible to file an amended return. The period in which amendments to
returns can be made depends on the tax type.
2.3 HMRC can undertake a compliance check to check for errors in a tax return.
For example, under ITSA, HMRC can correct or amend any obvious errors or
mistakes made by the taxpayer by amending their tax return within 9 months of
the date the return was delivered. This is not the case for all tax types.
2.4 HMRC recognise that the current processes for making amendments are not
consistent across the taxes. For example, taxpayers can currently amend ITSA
returns online, manually, and make some amendments by phone. They are not
restricted to amending in the same format that the return was originally made
(e.g. a person filing online can still amend on paper or by phone). Whereas
depending on the circumstances, amendments to VAT returns may be made on
subsequent returns or may have to be notified separately on paper.
Amending ITSA returns
2.5 Taxpayer amendments to ITSA returns should usually be made within 12
months of the statutory filing date. The ability and period in which to amend a
tax return is therefore linked to the filing date for the particular return.
For example, if a taxpayer has filed a 2016-2017 return online (with a filing date
of 31 January 2018) they would be able to amend that return up to 12 months
after the filing date, so until 31 January 2019.
2.6 Where the taxpayer has informed HMRC of their chargeability on or before 5
October, following the end of year of assessment, but the tax return is not
issued until after 31 October, the taxpayer has three months from the date of
issue to file the tax return. The return can be amended up to 12 months after
the deadline for filing.
2.7 ITSA returns that have been filed online can be amended online or by paper.
The normal deadline for filing an ITSA tax return online is 31 January after the
end of the tax year. For example, an ITSA return for 2016-17 should generally
have been filed by 31 January 2018. Paper returns must be filed by 31 October
5
after the end of the tax year, so a deadline of 31 October 2017 for a 2016/17
paper return. Therefore, where the normal online filing deadline applies,
amended returns for 2016-17 must be made by 31 January 2019.
2.8 Where a paper return was filed, a mistake in the return can be amended by
downloading blank versions of the required pages and then sending those
revised pages to HMRC. Alternatively, taxpayers can write to HMRC with
details of the amendments.
2.9 Some amendments to ITSA tax returns can be accepted by phone, such as
where a taxpayer forgot to fill in an entry or wants to change an entry. HMRC
cannot accept whole return sections by phone – the taxpayer must complete
the missing pages online or by post.
2.10 Once the statutory window for making an amendment to the original return has
passed, neither HMRC nor the taxpayer can amend the return. In some
circumstances tax overpaid may be refunded up to four years after the end of
the year of assessment; but that does not affect the original return and self-
assessment which would be final and no longer subject to possible amendment
by HMRC or the taxpayer.
2.11 HMRC can undertake a compliance check to check for errors in an ITSA return.
A taxpayer may make amendments to their return during the course of a
compliance check which will be given effect to once the check is completed.
2.12 Further information on making an amendment to an ITSA return can be found
in Self Assessment tax returns guidance.
Amending CTSA returns
2.13 For CTSA returns, amendments should usually be made within 12 months of
the filing deadline. The deadline depends on the company year-end date. The
return can be amended online or by writing to the appropriate tax office
(regardless of how it was originally processed). The exceptions to this include
the Corporate Interest Restriction, which is a group filing, where amendments
can be made beyond the filing deadline.
2.14 Other than in very limited circumstances, HMRC has not prescribed the format
and content of an amended return or provided an official form for amending
returns. Generally, companies can amend CTSA returns informally in
correspondence or online.
2.15 HMRC can undertake a compliance check to check for errors in a CTSA return.
A company may make amendments to its return during the course of a
compliance check, these will be given effect to once the check is completed.
2.16 Further information on making an amendment to a CTSA return can be found in
CTSA guidance.

Amending VAT returns
2.17 Unlike an ITSA return or CTSA return, the VAT return cannot be refiled. If a
taxpayer discovers an error after filing a return, they may be able to make an
amendment on their next VAT return.
2.18 Errors on past returns can be adjusted on the next VAT return if:
it is for an accounting period that ended less than four years ago;
the error was not deliberate;
the value of the error is £10,000 or less, or
the value of the error is up to 1% of the total value of sales for the
accounting period (up to a maximum of £50,000).
2.19 VAT return errors that do not meet the conditions above must be notified on
form VAT 652 or by writing to HMRC with the details.
2.20 Further information on making an amendment to a VAT return can be found in
VAT Notice 700/45.
Questions

3. Potential policy approaches
Further evidence to support our findings
3.1 HMRC held informal consultation meetings with external stakeholders in
February 2018 to discuss several tax administration topics, including
amendments to returns. Discussions touched on the issues taxpayers (and
their agents) face in making an amendment. In relation to amendments we
have been told the following:
The different ways of making amendments cause confusion.
Taxpayers want to have the same process regardless of when it is
invoked.
Taxpayers want a process that is digitised end-to-end.
Taxpayers want to be able to explain why they made an amendment up
front (including being able to attach supporting documents).
Taxpayers want a receipt and acknowledgement of an amendment.
HMRC should consider the process when agents are taking over clients
in the middle of an amendment. Taking over clients is apparently a
problematic time in any agent process.
What the future holds
3.2 Following the brief engagement to date on the subject of amendments, the
government is seeking to understand the experience faced by a taxpayer when
making an amendment to a tax return. The government wishes to consider
suggestions for a method of correction that works for all tax returns and makes
amendments more transparent and simple.
3.3 Although we have referred to ITSA, CTSA and VAT in this document, we are
also interested in your views on return amendment processes for other
taxes/duties administered by HMRC.
3.4 We want to create a consistent digital approach, whilst still accommodating the
digitally assisted and excluded, to make it simple for taxpayers to see their
returns and make amendments where necessary.
