An interactive costing · Rebuilding Middle Britain

Be the Chancellor:
tax wealth, free the wage

Set every lever the white paper proposes — rates on capital and on earned pay, the spending that reaches middle-income households, and the statutes that decide whether any of it survives contact with reality. Then read the books: surplus or deficit, borrowing, debt, and what lands in a nurse's payslip.

Your Budget

SET

Each section shows its running total. Open any of them.

A · Taxes on wealth & capital£0.0bn
Annual wealth tax rate1.0%
0%2.5% recommended peak3%

On individual net worth above the threshold. The Wealth Tax Commission costed 1% above £2m at roughly £16bn a year. Yield peaks near 2.5% and falls beyond it.

Threshold£2.0m
£1m£50m

The nisab principle — liability attaches only above a high floor, exempting ordinary living assets.

Productive reinvestment credit0%
nonefull relief

Discount for capital deployed in job-creating enterprise, R&D or green infrastructure.

Capital gains tax, top rate24%
24% today45% aligned

Aligning capital with labour. Yield turns down past the mid-30s as realisations are deferred.

Dividend tax, upper rate34%
33.75% today45%

The other half of the labour–capital asymmetry the paper identifies.

B · Taxes on earned income£0.0bn
Basic rate20%
15%25%

The broadest lever in the system — about £8bn per point. Falls squarely on Middle Britain.

Higher rate40%
35%50%

About £2bn per point. Now paid by teachers and sergeants, not only the affluent.

Additional rate45%
40%55%

Close to its revenue-maximising point; yield per point is small and falls as the rate climbs.

Employee National Insurance8%
4%12%

Main rate between the thresholds. A tax on earned pay alone — never on wealth.

Personal allowance£12,570
£12,570 frozen£20,000

Frozen since 2021. Roughly £6.5bn per £1,000 of unfreezing.

Higher rate threshold£50,270
£50,270 frozen£80,000

The paper's target is £70,000+. Roughly £1.3bn per £1,000.

C · Spending that reaches the middle£0.0bn

Transfers and services aimed at the same cohort. Each carries its own multiplier — childcare and skills raise labour supply as well as demand.

Childcare entitlement£0.0bn
£0£12bn

The strongest lever here: it removes a second-earner barrier, so it buys labour supply as well as demand.

NHS capacity & waiting lists£0.0bn
£0£20bn

Long waits hold working-age people out of the labour force; clearing them returns some of them to it.

Housing supply & first-time buyers£0.0bn
£0£15bn

The paper's third functional test of middle-class status: accumulating equity through ownership.

Schools, FE & skills£0.0bn
£0£15bn

Slow-burning, but it is the mechanism by which the mobility ladder is rebuilt.

Transport fare cap£0.0bn
£0£8bn

Cost-of-living relief that reaches commuters directly and shows up fast.

D · Legislation & administration0 in force

Statutes change what a rate actually collects, and whether the package survives politically. These are the paper's §4.4 and §5.2 recommendations.

The public finances

BORROWING & DEBT

Baseline: £75bn of borrowing, 2.6% of GDP, with net debt at 95.5% and drifting. Your budget moves both lines.

MACRO

Pounds move from holders with a marginal propensity to consume of 0.05–0.15 to households at 0.60–0.85, and the difference circulates. Baselines are the OBR's.

Annual change in take-home pay by gross salary. The shaded band is the paper's Middle Britain corridor — 75% to 200% of median, roughly £28,000 to £75,000.
