Statement of policy with respect to the exercise of the power to

make retrospective legislation within the Welsh Tax Acts etc.

(Power to Modify) Act 20XX

1. Background


1.1 The Welsh Tax Acts etc. (Power to Modify) Act 20XX (“the Act”) operates to

enable changes to be made to the Welsh Tax Acts1, by regulations where the

Welsh Ministers consider that such changes are necessary or appropriate and

where they are required to have effect immediately or shortly thereafter. Those

changes will be permitted in order to respond to a number of external

circumstances. In summary:

i. to ensure the devolved Welsh taxes are not imposed where to do so would be incompatible with any international obligations;

ii. to protect against tax avoidance in relation to devolved Welsh taxes;

iii. to respond to changes made by the UK government to ‘predecessor’2 UK taxes (that is, one where we have an equivalent devolved tax) which affect, or may affect the amount paid into the Welsh Consolidated Fund3, and

iv. to respond to decisions of the courts/tribunals which affect or may affect the operation of the Welsh Tax Acts, or any regulations made under them.

1.2 The primary intended effect of the Act is to provide Welsh Ministers with a

proportionate mechanism to protect Welsh tax revenues raised through devolved

taxes, and to avoid adverse implications for businesses, the property market, and

the environment.

1.3 The regulation making powers will not be used to achieve routine policy changes

to the devolved taxes. For such changes the Welsh Government will use powers

that already exist in the Welsh Tax Acts or, where necessary, primary legislation.

1 “The Welsh Tax Acts” are defined as The Land Transaction Tax and Anti-avoidance of Devolved

Taxes (Wales) Act 2017 (‘the LTTA’), the Landfill Disposals Tax (Wales) Act 2017 (‘the LDT’) and the Tax Collection and Management (Wales) Act 2016 (the “TCMA”).

2 ‘Predecessor taxes’ currently refers to Stamp Duty Land Tax and Landfill Tax – the UK equivalents for the taxes that are now devolved in Wales.

3 Under section 118(1) Government of Wales Act 2006. 3 see section 2(1)(c) of the Act


2. The Statement - Retrospective Legislation

2.1 Changes to tax legislation will normally take effect no earlier than the date the

regulations are made. However, a change which takes effect from a date earlier

than the date of making will also be possible for regulations made using the Act4,

although this is intended to be used in exceptional circumstances only.

Consideration as to whether to make regulations which give retrospective effect

will be decided on a case by case basis, depending upon the particular

circumstances. In all such circumstances, however, the regulations will be

subject to Senedd approval, be they subject to the draft or made affirmative


2.2 Examples of situations where the Welsh Ministers may consider making

regulations with retrospective effect include:

 where a change is made by the UK government that has immediate effect and provides a tax, and therefore commercial, advantage to entities liable to the predecessor tax,

 where a change is made by the UK government that has immediate effect and raises significant amounts of tax by a predecessor tax which will have a material effect on the block grant adjustment,

 where avoidance needs to be halted,

 where a court decision means the legislation may not be interpreted as intended by the Senedd when it was enacted, and

 where regulations have been made using powers in the Act (either by draft or made affirmative procedure) and the Welsh Ministers wish to amend the effect of the regulations, so that the changes have effect from the same date that the original regulations had effect.

2.3 The Welsh Ministers will ensure that the regulations made will be proportionate

and compatible with the European Convention on Human Rights6.

4 see section 2(1)(c) of the Act 5 Draft affirmative regulations must be laid in draft for at least 20 days before a Senedd vote can be held to approve them. Made affirmative regulations can come into force with immediate effect once

made by the Welsh Ministers, approval by Senedd vote must be given within a maximum period of 60 days for those regulations to remain in effect. 6 “The Convention Rights” which have been incorporated into UK law via the Human Rights Act 1998.


3. Timing and Communication of Changes

3.1 Whilst the Welsh Ministers will usually seek to make tax announcements as part

of the Draft Budget Statement where possible, it is necessary to recognise that

the intended use of the power provided by the Act is to respond to external

events. As a result, it is likely that the use of this power will fall outside the time

period that would permit an announcement to be made as part of the Welsh

Government’s Draft Budget. Changes are therefore most likely to occur outside

the first Draft Budget Statement. Where possible, the Welsh Government and

the Welsh Revenue Authority will use their communication channels and known

stakeholders to raise awareness of the changes in advance (in particular the

Written Statement and the details or annexes contained therein).

4. Procedure

4.1 When bringing forward retrospective legislation it is the Welsh Ministers’ intention

to abide by the following procedure:

- the outline of the proposed changes will be precise and provided by means of the Written Statement,

- the Written Statement will state the procedure that will be used and that the regulations will be made as soon as possible in line with relevant procedure and Welsh Government policies,

- the Welsh Ministers will write to the Chairs of the Finance Committee and the Legislation, Justice and Constitution Committee outlining the proposed changes and inviting the Committees to consider the purpose and effect of the retrospective legislation. Copies of the letters will be sent to the Llywydd, and

- The regulations will be published (and where appropriate made) as soon as possible.

4.2 Where is it possible to do so in the time allowed by individual circumstances, the

Welsh Government will seek views on the effect of the regulations, either

through a formal consultation where possible, or informally with trusted external

interested parties. However, given the nature of the regulations, particularly in

cases where amendments are required urgently it may not always be possible,

for example where the risk of forestalling arises.
