Autumn Budget · 26 November 2025

The Impossible Job

You are Rachel Reeves. It is November 2025. The OBR has handed you a deteriorating forecast — sluggish growth, £150bn borrowing, debt approaching £3 trillion. You must close the fiscal gap, meet your own rules, and avoid breaking your manifesto pledges. Move the sliders. Make your choices. See the consequences.

Starting Position — UK Public Finances, November 2025
£150bn
Annual borrowing (2024–25) — highest since pandemic
~95% GDP
Public debt-to-GDP — must fall by 2029–30 under fiscal rules
1.5%
OBR average GDP growth forecast (five-year) — downgraded again
3.5%
Inflation (2025) — well above 2% target, driving spending pressure
Labour Manifesto Constraints you must respect:
No increase in Income Tax rates, employee National Insurance, or VAT  ·  PSNFL must be falling as % of GDP by 2029–30  ·  Current spending to be covered by tax receipts  ·  Infrastructure investment commitments maintained
Your Budget Decisions
💰 Revenue Measures
Income Tax Threshold Freeze
Current: Thresholds already frozen until 2028 (£12,570 personal allowance, £50,270 higher rate)

Extend the freeze further — or end it early and raise thresholds above inflation to ease the cost-of-living burden.

End freeze early Extend 4 more yrs No change
Salary Sacrifice Pension NIC Relief
Current: Unlimited NI relief on salary sacrifice pension contributions — costs ~£7bn/yr to Treasury

Cap NI relief on pension salary sacrifice — raising revenue but reducing incentives for private retirement saving.

Keep generous Cap tightly No change
Wealth & Property Taxes
Current: No mansion tax; dividend/savings tax rate at 8.75%/33.75%; CGT at 18%/24%

Introduce a high-value property surcharge ("mansion tax") and raise rates on investment income — or keep wealth taxes light to avoid capital flight.

Light touch Aggressive No change
Gambling & Sin Taxes
Current: Remote gaming duty at 21%; general betting duty at 15%

Raise duties on remote gambling and online betting — politically popular but limited revenue yield.

Hold rates Sharp rises No change
Corporation Tax Rate
Current: £90bn annual yield at 25% main rate — roadmap pledged stability to 2030

Adjust the rate: cut to boost investment and signal pro-business credentials, or raise to close the fiscal gap faster.

Cut to 20% Raise to 30% 25% (no change)
✂️ Spending Choices
Welfare & Benefits
Current: £230bn+ welfare spend; two-child limit costs £3bn/yr to remove; welfare U-turns from summer already budgeted

Abolish the two-child benefit cap and restore winter fuel payments — or hold the line on eligibility to protect fiscal headroom.

Hold/tighten Expand & restore No change
NHS & Public Services
Current: £168bn NHS England budget; waiting lists remain a core political pressure point

Boost NHS funding to cut waiting lists and deliver on your top manifesto pledge — or demand efficiencies to keep spending flat.

Find efficiencies Major boost No change
Defence Spending
Current: ~2.3% GDP on defence; PM has committed to reaching 2.5% by 2027, funded by cutting overseas aid

Accelerate the path to 2.5% GDP — signalling strength to NATO allies — or slow the ramp-up to ease near-term fiscal pressure.

Slow ramp Accelerate fast No change
Departmental Day-to-Day Spending
Current: Real-terms departmental spending flat or falling in many areas outside NHS/defence

Inject new money into schools, policing, local government — or enforce spending restraint to demonstrate fiscal discipline to markets.

Restraint Significant boost No change
📈 Growth & Investment
Infrastructure & Housebuilding
Current: Planning reforms underway; housing target 1.5m homes by 2030; OBR estimates reforms add 0.2% to GDP

Accelerate capital investment and housebuilding — borrowing more now for long-run supply-side gains — or scale back to limit near-term borrowing.

Scale back Accelerate No change
Business Incentives & Skills
Current: £3bn skills budget; Employers NIC raised to 15% from Apr 2025 putting pressure on hiring

Offset the employer NIC impact with enhanced investment allowances and skills funding — or accept the cost and direct money elsewhere.

Scale back Enhance No change

    Economic & Political Outlook

    What did Reeves actually do? The real Autumn Budget 2025 (26 Nov) extended the income tax threshold freeze by 3 years to 2031, capped salary sacrifice pension NIC relief at £2,000/yr (from 2029), introduced a mansion tax surcharge of £2,500–£7,500 on homes worth £2m+ (from 2028), raised gambling duties sharply (remote gaming duty to 40%), kept corporation tax at 25%, abolished the two-child benefit cap, gave the NHS a significant cash injection, and accelerated defence spending toward 2.5% GDP. The result: taxes rose to an all-time high of 38% of GDP, fiscal headroom increased to £22bn, and the OBR forecast sluggish growth of 1.5% per year over the parliament.
