How a New Government Could Change Your Tax (2026/27)

Every general election brings a fresh round of tax promises. Some parties pledge to cut income tax, others promise to raise it for higher earners, and almost all claim they can fund better public services without hurting "working people." This guide looks at what the main UK parties have historically proposed and what a change of government could realistically mean for your take-home pay in 2026/27 and beyond.

The current landscape (2026/27)

As of 2026/27, the income tax Personal Allowance remains frozen at £12,570, and the higher-rate threshold at £50,270. National Insurance thresholds have been similarly frozen, meaning inflation has been dragging more people into higher tax bands — a policy known as fiscal drag. Any incoming government inherits this baseline.

Conservative proposals (historical pattern)

The Conservative Party has traditionally favoured cutting National Insurance rates over income tax changes. Their 2024 manifesto included a further 2p NI cut and a long-term aspiration to eventually abolish employee NI entirely. They tend to keep the Personal Allowance frozen (to raise revenue quietly) while offering headline-grabbing rate cuts.

Impact on you: A 2p NI cut on £35,000 salary saves roughly £350/year. However, if thresholds remain frozen and wages rise with inflation, you lose more through fiscal drag than you gain from a small rate cut.

Labour proposals (historical pattern)

Labour has typically pledged not to raise income tax, NI, or VAT for those earning under £80,000–£100,000. Instead they look to raise revenue through windfall taxes, closing tax loopholes, and increasing Capital Gains Tax or reforming non-dom status. Their approach tends to affect higher earners and business owners more than PAYE employees.

Impact on you: If you earn under £80,000, your take-home is unlikely to change directly. If you earn above that, or have significant investment income, expect a larger tax bill through increased CGT rates or reduced allowances.

Liberal Democrat proposals

The Liberal Democrats have historically pushed for raising the Personal Allowance (they championed the increase to £12,500 in the 2010–2015 coalition). They also tend to favour hypothecated taxes — specific levies ring-fenced for health or social care. A 1p income tax rise for the NHS has been a recurring proposal.

Impact on you: A 1p income tax rise on a £35,000 salary costs approximately £225/year. But if combined with a Personal Allowance increase to, say, £15,000, lower earners could still be better off overall.

Reform UK proposals

Reform UK has proposed raising the income tax threshold to £20,000 and cutting the basic rate to 18p. These are large structural changes that would significantly increase take-home pay for most earners, but would require substantial spending cuts to balance.

Impact on you: On £35,000, a £20,000 Personal Allowance and 18% basic rate would save approximately £2,700/year compared to the current system. The debate is whether such cuts are fundable without reducing public services.

What actually matters for your pay

Regardless of who wins, several factors determine your real take-home change:

  • Threshold freezes vs. uprating: unfreezing the Personal Allowance would benefit everyone; keeping it frozen is a stealth tax rise
  • NI rates vs. income tax rates: NI cuts only help earners between the Primary Threshold and Upper Earnings Limit; income tax cuts help at all levels above the PA
  • Pension policy: changes to tax relief on pension contributions (e.g., flat-rate relief at 25%) would dramatically affect higher earners
  • Student loan plan changes: Plan 5 terms or retrospective changes to Plan 2 affect graduates heavily

Model your scenarios

Use the income tax calculator to model different scenarios — try adjusting your Personal Allowance, tax rates, and NI to see what each party's proposals would actually mean for your monthly take-home.
