20th February 2026
January is always a strong month for government revenues, but this year's figures contained a striking anomaly. Capital Gains Tax (CGT) receipts jumped to unusually high levels, far above the normal seasonal spike that accompanies self‑assessment payments.
While the ONS hasn't yet published a detailed narrative, the underlying drivers are clear enough to sketch the story and it's a story about behaviour, policy, and the shifting structure of the UK economy.
This surge isn't happening in isolation. It sits alongside rising income‑tax receipts and a more subdued performance from corporation tax. Taken together, these trends reveal something important about where the tax burden is falling, who is paying it, and how the economy is evolving.
The January Spike
Why CGT Jumped So Dramatically
CGT is paid mainly through the self‑assessment system, which means January is always the peak month. But this year's spike was exceptional, and several forces converged to produce it.
People Rushed to Realise Gains Before Allowance Cuts
The Government has been steadily reducing the CGT annual allowance:
from £12,300
to £6,000
and now to £3,000
This created a powerful incentive for investors, landlords, and business owners to crystallise gains early. Tax advisers have been warning for months that this would produce a one‑off surge in disposals — and January's receipts reflect exactly that behaviour.
Asset Prices Rebounded And Gains Followed
CGT receipts lag asset‑price movements by a year or more. The strong recovery in:
equity markets
commercial and residential property
business valuations
...during 2024-25 is now feeding through into tax payments.
People who sold assets during the recovery are paying the tax now, in January 2026.
Higher Interest Rates Triggered Business Restructuring
The period of elevated interest rates forced many business owners to:
sell assets
restructure companies
exit investments
accelerate succession planning
All of these events generate capital gains.
Pandemic‑Era Losses Have Been Used Up
During the downturn, many investors accumulated losses they could offset against future gains. Those buffers have now been largely exhausted, meaning more gains are fully taxable.
Property Market Activity Picked Up
CGT applies to:
second homes
rental properties
inherited properties sold by beneficiaries
land sales
The property market stabilised in 2024-25, and those transactions are now showing up in the tax data.
How CGT Compares With Income Tax and Corporation Tax
The January figures don't just show a CGT spike — they reveal a broader shift in the UK’s tax base.
Income Tax
Rising Because of Fiscal Drag
Income‑tax receipts also rose sharply in January, but for different reasons:
wages have risen in nominal terms
tax thresholds have been frozen
more people are being pulled into higher tax bands
This is the quiet engine of revenue growth: fiscal drag. People are paying more tax without feeling richer.
Corporation Tax: Much Less Dynamic
Corporation‑tax receipts, by contrast, have been flatter.
Why?
business profits have been squeezed by higher interest rates
investment has been weak
many firms are still carrying forward pandemic‑era losses
the super‑deduction era is over, but its effects linger in the accounts
Corporation tax is no longer the buoyant revenue source it was during the pre‑pandemic years.
The Big Picture: The Tax Burden Is Shifting
The January data shows a clear pattern:
Individuals (through income tax and CGT) are carrying more of the tax burden
Businesses (through corporation tax) are contributing less than expected
Asset owners are paying more because of allowance cuts and rising valuations
This is a structural shift and not a one‑off blip.
What the CGT Surge Really Means
The spike in CGT receipts tells us several things about the state of the economy:
Wealthy individuals are restructuring their finances
The allowance cuts have forced action. People are selling assets earlier than planned.
Asset markets have recovered more strongly than the real economy
CGT rises when asset prices rise — even if wages and productivity don’t.
The Government is increasingly reliant on taxes paid by individuals
Income tax and CGT are doing the heavy lifting. Corporation tax is not.
This may be a one‑off peak
Once the allowance cuts are fully absorbed, CGT receipts may fall back.
It highlights the fragility of the UK’s tax base
A system that relies heavily on:
frozen thresholds
asset sales
one‑off behavioural responses
...is not a stable long‑term revenue model.
A Spike With a Story Behind It
January’s unusually high CGT receipts are not a mystery. They are the predictable result of:
policy changes
asset‑price recovery
business restructuring
and the timing of self‑assessment payments
But they also reveal something deeper: the UK is increasingly reliant on taxes paid by individuals, not companies, and on asset‑based revenues rather than productive growth.
It’s a spike worth celebrating if you sit in the Treasury.
But it’s also a warning sign about the shape of the economy beneath it.
Another Spike Is Possible Next Year - Here's Why
The January CGT spike is mostly about past behaviour, not the new property rules
The unusually high CGT receipts in January reflect:
people selling assets in 2024-25
people realising gains before the CGT allowance was cut
the rebound in share prices and property values
business owners restructuring due to interest rates
These are 2024-25 tax‑year events, paid in January 2026 through self‑assessment.
The new property‑tax changes weren’t in force yet, so they didn’t affect this spike.
The big property‑tax changes start affecting receipts next year
The UK Government has introduced several changes that will reshape how second homes, rental properties, and disposals are taxed. These include:
A. Abolition of multiple dwellings relief (MDR)
This affects landlords and investors buying multiple properties.
B. Restricting or removing furnished holiday let (FHL) tax advantages
This hits second‑home owners in tourist areas (including Scotland, if Westminster applies it UK‑wide).
C. Cuts to the CGT annual allowance
This is already affecting behaviour, but the full impact will show up next January.
D. Possible changes to property‑related CGT rates
The Government has signalled it may adjust rates in future fiscal events.
All of these will influence future CGT receipts — not the January 2026 spike.
So what happens next year? Expect another behavioural wave
When tax rules change, people act early. That’s exactly what happened with the CGT allowance cuts.
The same will happen with property:
Likely effects:
Landlords may sell before new rules bite
(especially those with marginal holiday lets or low‑yield rentals)
Second‑home owners may crystallise gains early
to lock in current CGT treatment
Developers and portfolio landlords may restructure
to avoid losing reliefs
Some may hold off selling
if they expect rates to fall or rules to soften
Net effect?
We could see another spike in CGT receipts next January — but it depends on how aggressively the Government pushes the reforms.
Scotland’s position is slightly different but the behavioural effect is UK‑wide
Even though property taxation is partly devolved, CGT is not.
So Scottish second‑home owners, landlords, and investors are affected in the same way as those in England.
However:
Scotland’s property market is cooler
fewer people own second homes
rural holiday‑let markets (Highlands, Moray, Aberdeenshire, Argyll) may be hit harder
Scottish landlords already face tighter regulation
This means the behavioural response in Scotland may be smaller, but still significant.
The big picture: January’s spike is the warm‑up, not the main event
To summarise:
This year’s spike = people acting before allowance cuts + asset‑price rebound
Next year’s spike (or slump) = people reacting to the new property‑tax rules
The Treasury knows this.
They expect volatile CGT receipts over the next two years as people adjust.
