Can MPs amend the Budget?

MPs can propose amendments only to the first Budget Ways and Means motion. Any of the other Budget motions can be voted upon but they cannot be amended. This is because under Standing Order No. 51(3) where there is a series of motions the second and subsequent motions have to be put ‘forthwith’ – that is, without amendment or debate.

This guide is part of the collection: How does Parliament authorise the Government's taxation plans? A procedural guide to the Budget process

An amendment to the first Budget motion must be tabled, selected and moved, in order for a vote on an amendment to take place.

Limits on the power of amendment

The rules of order for amendments engage the constitutional principle of the financial initiative of the Crown. This precludes Parliament from seeking to impose taxes (or grant permission for public expenditure) unless requested to do so by the government.

MPs who are not Ministers therefore cannot increase ‘a charge upon the people’, extend the objects and purposes of a charge, or relax the conditions and qualifications set out by the government when recommending a charge, as this would trespass on the constitutional preserve of the government.

MPs can seek only to reduce a tax rate or increase a tax relief, provided that the result of their amendment is not an increase in the charge (compared to the situation prior to their proposed change).

Restrictions on the scope for amendments

The scope for amendment is determined by the scope of the first and only amendable Ways and Means motion tabled at the start of the debate.

Historically, this motion has often taken the form of an ‘Amendment of the Law’ motion. This usually contains the statement that:

“it is expedient to amend the law with respect to the National Debt and the public revenue and to make further provision in connection with finance”.

Provisions to restrict the scope are usually also incorporated into the motion so the room for MPs to amend it is quite limited. However, this motion does enable the opposition – or indeed government backbenchers – to table amendments setting out alternative tax provisions which can, if selected, then be debated and voted on.

If the Government chooses not to table an Amendment of the Law motion, then the first Ways and Means motion generally takes the form of a motion for the charging of income tax. This usually contains the statement:

"That income tax is charged for the tax year [2021-22].
And it is declared that it is expedient in the public interest that this Resolution should have statutory effect under the provisions of the Provisional Collection of Taxes Act 1968."

For an amendment to this motion to be selected it must concern the annual charge on income tax. The scope for amendment is thus very limited.

Historically, the tabling of an Amendment of the Law motion has been the norm, except where Budgets have taken place shortly after a general election or when the dissolution of Parliament is anticipated (May 1929; February 1974; May 1997; May 2010; June 2017).

However, since 2018 the government has chosen not to table an Amendment of the Law motion for any Budget, favouring a motion for the charging of income tax, thus limiting MPs scope for amendment.

Does the scope for amendment affect the Finance Bill?

Yes, as well as limiting the scope for debate and amendment of the first Budget motion, the form of the first Budget motion to be moved – that is, whether it is an Amendment of the Law motion or not – also affects the scope for amendment of the subsequent Finance Bill.

For example, an Amendment of the Law motion, if passed, might provide scope for MPs to table amendments to the Bill in areas which may not be covered by the Budget such as tax administration, tax avoidance or tax relief. The absence of an Amendment of the Law motion limits this possibility.

What happens if the Budget proposals are successfully amended?

Amendments to the government’s Budget proposals are rare but not unknown. For example:

in December 1994 the House supported an amendment to freeze VAT on domestic fuel at 8%, in place of the government’s proposed increase to 17.5%;
in March 2016 the government’s proposals were amended to provide for VAT relief on women’s sanitary products.

However, if any of the government’s proposals are amended, then a new Ways and Means motion (or motions) must be introduced to compensate for any lost revenue.

The new Leader of the Opposition, Kemi Badenoch, makes her debut at Prime Minister’s Questions. The Budget debate concludes with votes on the "founding" resolutions for the Finance Bill. But why is a separate bill for National Insurance changes needed? The Treasury Select Committee questions the Chancellor of the Exchequer, along with other leading economic experts. The Business and Trade Select Committee hears from Sir Alan Bates and other victims of the Post Office Horizon scandal about "fast and fair redress." And a draft Statutory Instrument to extend bus franchising powers to all local transport authorities in England will be debated by both Houses.

News / The Budget: Why aren't MPs told first? - Parliament Matters podcast, Episode 51

The Speaker, Sir Lindsay Hoyle, has criticised Ministers for leaking the content of the Budget. But Ministers have strong incentives to “pre-leak” plans, making the practice unlikely to stop, especially as the Speaker has limited power to penalise them. We also discuss the sub judice rule, which bars MPs from commenting on ongoing court cases amid controversy about the handling of the Southport murder case. Finally, former Liberal Democrat minister David Laws offers insights into a century of Labour-Lib Dem relations as we explore what the future holds for the Liberal Democrats in Parliament.

Publications / What’s the point of petitions? What the last century reveals about petitioning and people power in modern Britain

Petitioning has been one of the most popular and persistent forms of political participation since the dawn of mass democracy in Britain. But little is known about its development throughout much of the 20th Century. Contrary to received wisdom at the time or since, petitioning did not become irrelevant or old-fashioned in the era of universal suffrage. Moreover, petitioners often held more subtle or sophisticated definitions of ‘success’ than those who condemned the practice as ineffective.
