Here we go again. Chancellor Rachel Reeves is hunting for cash—around £30bn worth—and economists reckon another National Insurance Contributions (NICs) shake-up is the most likely target. If you thought last year’s employer NICs hike was painful, buckle up. This autumn Budget could bring a whole new wave of tax changes that’ll hit businesses, landlords, and even your pension.
Oxford Economics predicts the Treasury’s eyeing up around £15bn in extra tax revenue through a mix of NICs tweaks and income tax freezes. So what’s actually on the table?
What’s Likely to Change?
Income Tax Freezes Extended (Again)
The big one? Freezing income tax allowances and NICs thresholds until 2029/30. That’s fiscal drag in action—millions more workers getting pulled into higher tax brackets without a pay rise. Expected haul: £10bn.
It’s a stealthy tax rise that doesn’t break Labour’s manifesto promise. Clever? Sure. Popular? Not so much.
NICs Coming for Your Pension Contributions
Right now, employer pension contributions are NICs-free. That could change. If Reeves slaps a new NICs rate on private company pension contributions, it’ll raise around £2bn—and potentially make employers think twice about generous pension schemes.
Landlords and LLPs in the Crosshairs
Landlords currently dodge NICs on rental income. That exemption might disappear, bringing in another £2bn. Limited Liability Partnerships—think law firms and investment funds—are also likely targets, adding £1bn to the pot.
These aren’t huge revenue raisers individually, but they add up fast when you’re plugging a £30bn hole.
What Reeves Probably Won’t Touch
Despite the pressure, don’t expect headline-grabbing rate hikes. Michael Saunders from Oxford Economics reckons increases to income tax, VAT, employee NICs, or corporation tax are “highly unlikely” given Labour’s manifesto pledges.
Another employer NICs rate rise? Also doubtful. Last year’s increase hammered retail and hospitality sectors hard, and the inflationary fallout is still fresh.
Instead, the focus is on broadening the tax base—finding new things to tax rather than hiking rates on existing ones.
Banks and ‘Sin Taxes’ on the Menu
Banks should brace themselves. A new windfall tax is reportedly in play, alongside higher levies on betting and other “sin taxes.” Combined, these could raise £8bn.
There’s also chatter about pension tax relief changes—potentially capping tax-free lump sums at £100,000 and standardising relief at 30%. That’s another £5bn right there.
The Fiscal Tightrope
Whether Reeves can pull this off depends partly on the Office for Budget Responsibility’s productivity forecasts. If they’re optimistic, the Chancellor gets more wiggle room. If not, these tax hikes might just be the beginning.
Saunders points out that while tax rises and spending restraint might calm market nerves short-term, the UK still needs to prove it’s on a “solid path to fiscal sustainability.” Translation: this probably isn’t the last Budget squeeze we’ll see.
The Bottom Line
Rachel Reeves is facing a £30bn black hole and limited options. Expect income tax freezes, NICs base-broadening, and targeted raids on pensions, landlords, and banks. What you won’t see? Big manifesto-breaking rate hikes.
It’s classic stealth taxation: technically keeping promises while quietly reaching deeper into everyone’s pockets.

FAQ
Q1: Will my take-home pay be affected by these changes?
A: If you’re an employee, probably not directly—but if income tax thresholds stay frozen, you’ll drift into higher tax brackets over time. Employers facing higher NICs on pensions might also trim benefits or freeze pay rises.
Q2: Are these NICs changes confirmed?
A: Not yet. These are predictions from Oxford Economics based on the fiscal gap and Labour’s manifesto commitments. The actual Budget will reveal what’s official, but economists see these moves as highly likely.
Q3: Why is the government targeting NICs instead of income tax?
A: Because Labour promised not to raise income tax, VAT, or employee NICs rates. Broadening the NICs base—making more income types liable—technically keeps that promise while still raising billions.
Q4: How will landlords be affected?
A: If NICs are extended to rental income, landlords could face a new tax bill on their earnings. It’s part of the push to widen the tax base and capture income streams that currently escape NICs.
Q5: What should I do to prepare?
A: Review your pension contributions, tax planning, and overall financial strategy. If you’re a landlord or business owner, consult an accountant before the autumn Budget to explore any preemptive moves.
