Burnham Faces Push for Single Levy to Replace Key Taxes

Andy Burnham is being pushed toward a sweeping tax overhaul before he enters Downing Street, with economists urging him to consider replacing several major taxes with one broad national levy.

The proposal would merge income tax, National Insurance, capital gains tax, inheritance tax and other personal-tax streams into a single “national contributions” system applied across different forms of income and gains.

It is not government policy. It is an outside pressure document aimed at shaping the economic agenda of an expected incoming prime minister.

The proposal targets the split between work and wealth

The central claim behind the plan is that Britain taxes different income sources too unevenly.

Wages, dividends, capital gains and inheritances face separate rules, separate rates and separate political protections.

A single levy would try to collapse that structure into one framework.

Supporters argue that the current system is complex, distorts behaviour and places too much visible pressure on workers while allowing other forms of income to be taxed differently.

The proposal’s political appeal is simplicity. Its political danger is that almost every simplification creates winners, losers and a new fight over fairness.

National Insurance is the hardest piece

National Insurance is not just another tax in public perception.

Workers see it on payslips, employers pay it through payroll, and voters often connect it to pensions, benefits and the NHS even when the modern public-finance reality is more complex.

The Office for Budget Responsibility estimated National Insurance contributions at £205.4bn in 2025-26, making it one of the largest UK revenue streams.

That scale explains why economists target it for reform and why politicians fear touching it.

Any plan to fold National Insurance into a broader levy would need to explain how pension entitlement, employer contributions and take-home pay change.

Without that detail, the proposal risks being attacked as a stealth tax before it reaches Parliament.

The £75bn claim will face scrutiny

Supporters of the Prosperity 2030 approach argue that the wider reform package could raise tens of billions in additional revenue over several years.

That number is the first place critics will test the plan.

Tax reforms can look powerful on paper and shrink under behavioural response, avoidance planning, transitional reliefs and political carve-outs.

High-value estates, asset sales and capital gains are especially sensitive to timing. People can defer, restructure or move transactions if they know a new regime is coming.

A credible Burnham Treasury would need independent costing before adopting anything close to the full plan.

Property tax reform may be the easier route

The proposal also includes scrapping council tax and stamp duty in favour of a national levy on property value.

That part may attract more attention because UK property taxation is widely criticised as outdated and uneven.

Council tax is still based on old valuation bands, while stamp duty can discourage moving and make the housing market less flexible.

A property-value levy would create its own political danger. Homeowners in high-value areas could face higher annual bills even if their income is not high.

That is why property-tax reform often looks rational in reports and brutal in constituency politics.

Burnham’s first problem is credibility

Burnham’s allies want a break from what they see as fiscal caution and public-service decline.

Markets will want reassurance that reform does not mean unfunded promises.

Voters will want to know whether the plan raises their household tax bill.

That gives Burnham a narrow early path: he can welcome serious tax debate without adopting the most radical package immediately.

He can also use the proposal to signal that public-service funding, property taxation and work incentives are on the table.

The risk is that opponents define the whole agenda as a tax raid before Burnham defines it himself.

The proposal is also a public-services argument

The single-levy plan is not only about collection mechanics.

Supporters want the proceeds spent on universal services such as transport, meals for primary schoolchildren and wider social infrastructure.

That makes it a broader political offer: higher or broader taxation in exchange for visible everyday services.

The challenge is trust.

British voters have heard promises of better services before. If the tax rise feels immediate and the service improvement feels delayed, the bargain weakens.

Burnham’s Manchester record gives him language around devolution, buses and local services, but national tax reform is a different scale of risk.

Critics will focus on implementation

The biggest obstacle may not be ideology.

It may be execution.

Merging major taxes would require payroll changes, HMRC system redesign, transitional rules, pension and benefit clarifications, investment-income treatment, inheritance treatment and anti-avoidance protections.

The government would also need to decide whether employers pay the levy, whether pensioners pay it, how self-employed income is handled and how devolved finance is affected.

Those questions are not technical footnotes. They decide the political outcome.

A reform sold as simplification can become a bureaucratic fight if the transition is not clear.

The next signal will come from Burnham’s team

The open letter is designed to force an answer before the new government settles.

Burnham can ignore it, endorse the principle, commission a review or fold parts of the idea into a future Budget process.

The more likely early move is a review rather than instant adoption.

That would let him claim reformist ambition while avoiding a market shock before his chancellor and Treasury team are fully in place.

The proposal has still done its job. It has put tax-system redesign, not just rate changes, into the opening debate around a Burnham government.
