Rachel Reeves has just painted herself into a corner, and Liberal Democrats must be ready to offer the escape route Britain needs.

As Wimbledon reaches its climax, there’s a lesson for Liberal Democrat strategy: the greatest players don’t just react to their opponent’s shots, they anticipate them. With Labour’s recent U-turn on disability benefit cuts, their retention of the two-child benefit cap, and their “triple tax lock” commitment, an autumn tax squeeze is now inevitable. The question isn’t whether it’s coming, but whether we’ll be ready with better alternatives.

Reading the Court

Labour have served themselves into a corner. Having pledged not to raise income tax, National Insurance, or VAT rates. the three taxes that generate £520bn annually, two-thirds of all government revenue, while facing mounting spending pressures, Chancellor Rachel Reeves is rapidly running out of options. The disability benefit U-turn alone adds £3bn to her fiscal gap, while winter fuel payment cuts save just £1.5bn.

This isn’t speculation. The Treasury Select Committee’s 2021 report “Tax after coronavirus” mapped out exactly this scenario, warning that the Conservative “triple tax lock” would come under severe pressure and force governments toward regressive alternatives.

The Treasury Committee’s Prophetic Warnings

What they predicted in 2021:

✅ “Triple tax lock” would become unsustainable
✅ Governments would resort to fiscal drag through frozen thresholds
✅ Capital taxes would be targeted for “quick wins”
✅ Pension tax relief would face restrictions
✅ National Insurance increases would damage employment (Sunak ignored this, and later reversed)

Every warning is now Labour’s reality.

Anticipating Labour’s Shots

So where will Labour’s autumn shots land? The Treasury Select Committee report provides clear clues about the limited options available:

Fiscal Drag Through Frozen Thresholds The Committee noted governments “could raise revenue simply by freezing income tax thresholds.” It’s the easiest way to raise taxes without breaking manifesto promises, but deeply regressive. Freezing all thresholds could raise £8bn by 2025, but would hit a teacher earning £35,000 proportionally harder than a CEO earning £350,000.

Capital Gains Tax Raids The Committee found a “compelling case for reform” of capital taxes. Expect CGT rates to rise from 20% to match income tax rates, and the £3,000 annual exemption to vanish entirely, raising perhaps £14bn but catching middle-class savers alongside the genuinely wealthy.

Pension Tax Restrictions The report highlighted the “regressive nature” of current pension tax relief. The lifetime allowance could return at £1m, or relief could be capped at the basic rate, hitting middle-class savers while leaving wealthy offshore arrangements untouched.

Stamp Duty Manipulation Higher rates on properties above £500,000 while claiming to help first-time buyers, the classic Labour playbook that raises £2bn while making family homes even less affordable.

What Happens If We Don’t Act?

Without preparation, we’ll be left issuing predictable press releases about “stealth taxes” while Labour frames us as unserious about public finances. We’ll watch from the sidelines as:

• Middle-income families lose another 5% of disposable income to fiscal drag
• Young professionals give up on homeownership entirely
• Small business owners face CGT bills that dwarf their actual profits
• Labour claims they “kept their promises” while picking taxpayers’ pockets

Labour spent five years attacking Conservative stealth taxes. Now they’re reaching for the same regressive playbook, proving they’re out of progressive ideas.

Our Return Strategy

The greatest tennis players don’t just defend, they turn defence into attack. While Labour’s moves may be politically inevitable, they represent a fundamental failure of progressive tax policy. As a former City Councillor who’s seen how national tax decisions affect local communities, I know we can do better. To give some examples of potential policies:

Fairer Taxation of Unearned Income

Where Labour will tinker with capital gains rates, we should address the fundamental unfairness that sees unearned income taxed more lightly than wages. Rather than unworkable wealth taxes, we should:

• Equalise capital gains and dividend tax rates with income tax, raising £12bn
• Reform council tax with new bands above £500,000 and regular revaluations
• Introduce a proportional property tax replacing stamp duty, making the system fairer while raising similar revenue
• Close inheritance tax loopholes that let the wealthiest estates pay just 10% effective rates

Corporate Tax Justice

The Committee supported “moderate increases” in corporation tax. We should go further, a minimum tax rate of 15% for all UK profits would raise £8bn from multinationals currently paying virtually nothing, while protecting genuine small businesses.
Digital Economy Leadership A 2% revenue tax on tech giants with UK revenues above £500m would raise £2bn annually, ensuring they pay their way in the communities they profit from, rather than Labour’s piecemeal approach. The US and Trump would hate it; but Canada is standing up to them on this and so should we.

Environmental Tax Transition

A properly designed carbon tax at £75 per tonne with full redistribution to households could raise £15bn while giving every family a £600 annual carbon dividend, replacing Labour’s regressive alternatives while driving the transition to net zero.

Learning from Champions

The Treasury Select Committee’s 2021 report contains a crucial lesson. Its cross-party warnings about National Insurance increases were ignored by Rishi Sunak, who proceeded with exactly the policy experts advised against, a 1.25 percentage point increase that damaged employment and was later reversed, vindicating the Committee’s analysis.

We cannot afford to be similarly unprepared. Labour’s autumn tax moves are as predictable as a Djokovic baseline rally. If we wait until the Budget to respond, we’ll be scrambling to return shots that have already passed us by.

Getting to Centre Court

Currently polling fourth nationally, Liberal Democrats risk being seen as players who’ve lost their edge. While we’re the third largest party in Westminster, our policy offering often feels predictable, “join a customs union with the EU and growth will follow.” That’s not wrong, but it’s hardly the comprehensive economic vision voters need to hear.

Labour’s inevitable tax policy crisis presents a golden opportunity to move up the rankings. When Reeves inevitably unveils her regressive stealth taxes, we need to be ready with a credible alternative that puts us at the centre of the debate and that shows we’ve got better, more credible plans for progressive taxation than any other party.

Match Point: Our Action Plan

As someone who’s worked in finance and seen how these decisions play out in practice, I believe we need our parliamentary team developing comprehensive tax reform proposals now. Not as hasty reactions to Labour’s Budget, but as carefully prepared alternatives that demonstrate economic seriousness.

Immediate Next Steps:

1. By September: The party should issue a call for evidence across our membership and seek to identify our tax experts (accountants, economists, former treasury officials etc.,) to be drawn from in the future.
2. Before Conference: Parliamentary researchers should compile international best practices on wealth taxation
3. At Autumn Conference: Dedicate serious workshop time to tax reform and use that forum to test messages.
4. By October: Be ready with fully-costed progressive alternatives to close the fiscal gap (with an aim to removing the two-child benefit cap?)

Our MPs shouldn’t be doing this alone. The Liberal Democrats have deep expertise within our membership: tax professionals, economists, local government finance leads who understand how national decisions affect communities. Remember, it was a member-led initiative that developed our personal allowance policy, one of our greatest coalition successes. We need that same collaborative approach now.

The Treasury Select Committee showed us the court layout four years ago. Labour’s position is becoming increasingly predictable. We know they’ll need to raise at least £20bn in additional revenue. We know their options are limited by manifesto commitments.

The question is whether we’ll be ready with winning shots that actually deliver progressive taxation, or whether we’ll be left watching from the sidelines as Labour serves up another regressive tax squeeze.

The greatest players don’t just anticipate their opponent’s next move, they use it to climb the rankings. It’s time Liberal Democrats did the same.
