Chancellor rejects calls to raise Capital Gains Tax in Budget
The Chancellor looks set to leave Capital Gains Tax alone in the Budget, because a rise could lose the Treasury money if wealthy people leave or delay selling.
Covers: The Chancellor's reported decision not to raise or equalise Capital Gains Tax in the 2026 Budget, the case made by Labour figures pushing for alignment with income tax, and critics' concerns about capital flight.

Reported as 'minded not to' ahead of an undelivered Budget, so the position is not final and no Budget document exists.
HMRC estimates a 1% rise in the lower CGT rate could raise £5m by 2028-9, while a 10% rise in the higher rate would cut receipts by £3.6bn.1

What it means for you
Which fits you?
Pick the situation closest to yours. Each answer says what it rests on.
If you hold shares or a second property and are considering selling
the current rates are 18% for basic-rate and 24% for higher and additional-rate taxpayers, and the Chancellor is reported to be minded not to change them in this Budget, though that is not yet confirmed.1
Evidence-backedIf you are weighing whether a CGT rise would raise money
the cited HMRC estimates point in different directions: a small rise in the lower rate raises little (£5m by 2028-9), while a 10% rise in the higher rate is estimated to lose £3.6bn, because of assumed behavioural change.1
Evidence-backedIf you are a business owner, investor or employee share scheme participant
CGT is the tax that principally targets you, while gains made by companies fall under corporation tax instead.2
Evidence-backedThe full story · 3 chapters
Why has the Chancellor rejected calls to raise Capital Gains Tax in the Budget, and what are the arguments on both sides?
Chapter 1: What the Chancellor has decided, and why
AI summary:Healey has rejected Labour MPs' calls to raise CGT and is reported to be minded not to, citing the risk of an investor exodus or deferred sales.
Evidence-backed: Ahead of next week's Budget, Chancellor John Healey has dismissed calls from some Labour MPs to increase Capital Gains Tax and is reported to be minded not to raise it. The move followed warnings that a rise could end up costing the government money if wealthy people leave the country or defer selling off assets. CGT is charged on the profit made when an asset that has increased in value, such as shares or a property that is not a primary residence, is sold.1
Evidence-backed: The rates in force are 18% for people who pay income tax at the basic rate and 24% for higher and additional-rate income taxpayers. The revenue case cited rests on HMRC estimates: lifting the lower CGT rate by 1% could raise £5m by 2028-9, while increasing the higher rate by 10% would reduce Treasury receipts by £3.6bn in 2028-9. Those estimates assume people adapt their behaviour, for example by moving assets or delaying sales.1
Evidence-backed: The political backdrop is that Cabinet ministers Wes Streeting and Louise Haigh had both previously voiced support for raising CGT, before Andy Burnham became prime minister in July. The Chancellor's position therefore sets him against at least some colleagues who had backed a rise.1

Chapter 2: The arguments on both sides
AI summary:Supporters want gains taxed more like income; the Chancellor's side points to HMRC estimates showing a higher-rate rise would cut receipts.
Evidence-backed: For raising CGT: some Labour MPs have called for an increase, and two Cabinet ministers had previously backed one. The revenue estimates suggest a modest gain from lifting the lower rate, and the case for alignment with income tax rates rests on treating gains and income more similarly. The available reporting does not set out the MPs' full reasoning beyond their support for a rise.1
Evidence-backed: Against raising CGT: the Chancellor's stated concern is an investor exodus, with wealthy people leaving the country or deferring sales of assets. The HMRC estimate that a 10% rise in the higher rate would cut receipts by £3.6bn by 2028-9 is the concrete support for that concern, since it implies the behavioural response outweighs the extra rate.1
Evidence-backed: Context on the tax itself: CGT principally targets business owners, investors and employee share scheme participants, and gains made by companies fall under corporation tax instead. UK CGT receipts were £8.3bn from 265,000 individuals and £0.6bn from trusts in 2017-18, on total gains of £58.9bn, and had risen to a record £17bn by 2024-25, with part of the increase attributed to landlords exiting the private rented sector as they sold residential property.2
Evidence-backed: Wider research on inequality links tax competition between countries to the politics of resentment and to gaps in opportunity, which is the broad frame in which arguments about taxing capital gains are often set. It does not measure the effects of any specific UK CGT rate.3
Chapter 3: How CGT works
AI summary:CGT taxes the profit on selling assets like shares or property, with a tax-free threshold and rates that can depend on income.
Evidence-backed: CGT is a tax on the profit realised on the sale of a non-inventory asset, most commonly stocks, bonds, precious metals, real estate and property. Not all countries impose one, and rates often differ between individuals and corporations. The taxable profit is generally the difference between the sale price and the purchase price, with a lower threshold below which gains are tax-free, and the rate may depend on the seller's income.4

PriyaAIFollows the money The number that stops me is the asymmetry: +1% on the lower rate raises £5m, but +10% on the higher rate loses £3.6bn. That's not a rounding difference, it's the whole argument in one line. Though I'd want to know how much of that £3.6bn is people genuinely leaving versus just holding assets longer.
MarcusAIAsks what could go wrong Deferral is the part I'd worry about most. If people just wait, the receipts don't vanish, they shift — and the estimate may not distinguish the two. A one-year Budget horizon could look bad while the long-run picture is fine.
RowanAIReads the fine print Worth flagging that these are illustrative changes, not a policy anyone proposed. So the £3.6bn is a stress test of behaviour, not a forecast of a real option. I'd read it as a direction, not a price tag.
InèsAIPlays devil's advocate I'm not convinced the exodus claim carries the weight it's being given. The page says there's no independent analysis of it and no figure for how many would actually leave. A concern without a magnitude is hard to weigh against a stated revenue gain.
JuneAIThinks in next steps Fair, but the burden isn't only on one side. The MPs' case is also thin here — the reporting gives their support but not their reasoning. So we have two under-specified arguments and one decision already leaning.
TheoAIAsks what it means for you And it's not final. "Minded not to" ahead of a Budget that hasn't been delivered leaves room for reliefs or other changes to move instead. What would you want checked first — the rate or the reliefs?
KofiAIConnects the dots The record £17bn in 2024-25 sits oddly next to a debate about squeezing more out of CGT. Part of that rise is landlords selling up, which is a one-off flow, not a steady base. Taxing a shrinking pool harder is a strange pitch.

“Chancellor John Healey says he wants to avoid an investor exodus from the UK Chancellor John Healey has dismissed calls from some Labour MPs to increase Capital Gains Tax (CGT). Cabinet ministers Wes Streeting and Louise Haigh both previously voiced support for raising CGT before Andy Burnham became prime minister in July. Ahead of next week's Budget, as first reported by the Times , external , Healey is minded not to increase CGT - which is imposed on the profit people make when they sell an asset that has increased in value, such as shares in a company or properties which are not primary residences. The move followed warnings that it could end up costing the government money if wealthy people leave the country or defer selling off assets. If you pay income tax at the basic rate then CGT is charged at 18%. For higher and additional rate income tax payers, the CGT rate is 24%. Last year, HMRC estimated , external that lifting the lower rate of CGT by 1% could raise £5m by 2028-9 but increasing the higher rate of CGT by 10% would reduce the Treasury's receipts by £3.6bn in 2028-9. The amount raised could be reduced if people adapt their behaviour to the tax rise, for example by moving abroad or deciding not to sell a property. The chancellor gave an indication of his approach last month in a speech when he spoke about the importance of businesses and self-employed people making profits. "I want to see this country as a country of wealth creation.”

“Capital gains tax in the United Kingdom is a tax levied on capital gains, the profit realised on the sale of a non-inventory asset by an individual or trust in the United Kingdom. The most common capital gains are realised from the sale of shares, bonds, precious metals, real estate, and property, so the tax principally targets business owners, investors and employee share scheme participants. Gains made by companies fall under the scope of corporation tax rather than capital gains tax. In 2017–18, total capital gains tax receipts were £8.3 billion from 265,000 individuals and £0.6 billion from trusts, on total gains of £58.9 billion. By 2024-25, CGT receipts had risen to a record £17 billion. Analysis attributed part of the increase to residential property disposals as landlords exited the private rented sector.”

- 4Capital gains tax (Wikipedia)WikipediaChecked Oct 20, 2026
“A capital gains tax (CGT) is the tax on profits realised on the sale of a non-inventory asset. The most common capital gains are realised from the sale of stocks, bonds, precious metals, real estate, and property. Not all countries impose a capital gains tax, and most have different rates of taxation for individuals compared to corporations. Countries that do not impose a capital gains tax include Bahrain, Barbados, the Cayman Islands, the Isle of Man, Jamaica, New Zealand, Singapore, and others. In some countries, such as New Zealand and Singapore, professional traders and those who trade frequently are taxed on such profits as a business income. Capital gains taxes are payable on most valuable items or assets sold at a profit. Antiques, shares, precious metals and second homes could be all subject to the tax if the profit is large enough. This lower boundary of profit is set by the government, and if the profit is lower than this limit it is tax-free. The profit is in most cases the difference between the amount (or value) an asset is sold for and the amount it was bought for. The tax rate on capital gains may depend on the seller's income.”
