UK Tax Changes 2025/26: What's New This Year

Tax7 min readCalcStack Team

No single headline-grabbing reform this year. But the cumulative effect of frozen thresholds, slashed allowances, and higher employer NI means most people are paying more tax in 2025/26 than they were a year ago — without a single rate technically going up. That’s fiscal drag for you, and it’s the government’s favourite stealth tax. Here’s what actually changed.

Income Tax: Thresholds Frozen. Again.

The Personal Allowance stays at £12,570. The higher-rate threshold stays at £50,270. These have been frozen since 2021/22 and won’t move until at least April 2028. Since the Autumn Statement confirmed the freeze extension, wages have kept rising while the thresholds haven’t — pushing millions more into higher tax bands without any actual rate change.

The additional rate threshold is still £125,140 (reduced from £150,000 in April 2023). Above that: 45% income tax, no Personal Allowance.

National Insurance

Employee NI stays at 8% (it was 10% until April 2024, and 12% before January 2024). The Primary Threshold is £12,570, aligned with the Personal Allowance.

But here’s the big one: employer NI jumped from 13.8% to 15% in April 2025, and the Secondary Threshold dropped from £9,100 to £5,000. That’s a serious cost hike for businesses. If your employer seems reluctant to give pay rises this year, this is why.

Dividend Allowance

Still at £500. Down from £1,000 last year and £2,000 the year before that. Dividend tax rates haven’t changed (8.75%, 33.75%, 39.35%), but with the allowance this low, virtually every dividend you take is now taxable.

Capital Gains Tax

The annual exempt amount stays at £3,000 (down from £6,000 last year). But the rates went up in the October 2024 Budget: the lower rate rose from 10% to 18%, and the higher rate from 20% to 24% on most assets. These now match the residential property CGT rates. If you’re selling shares or a business, the tax bill is noticeably higher than it was.

Pensions

Annual allowance stays at £60,000. The Lifetime Allowance was scrapped in April 2024, replaced by a lump sum allowance of £268,275 and a lump sum and death benefit allowance of £1,073,100. The Money Purchase Annual Allowance (for people who’ve already accessed a pension flexibly) is still £10,000.

Stamp Duty

The temporary higher thresholds ended 31 March 2025. First-time buyer nil-rate band is £425,000 (maintained). Standard nil-rate band is £250,000. The additional property surcharge went up from 3% to 5% in October 2024 — a significant hit for landlords and second-home buyers.

High Income Child Benefit Charge

After April 2024’s changes to the dividend allowance, the HICBC threshold rose from £50,000 to £60,000, with the taper running to £80,000. Parents earning under £60,000 now keep full Child Benefit. A welcome change for many families.

Minimum Wage

The National Living Wage (workers 21+) went to £12.21/hour in April 2025, up from £11.44. For a full-time worker on 37.5 hours, that’s about £23,800/year. The age threshold dropped from 23 to 21 in April 2024.

What This All Means for You

The overall picture: higher effective tax rates for most people. Frozen thresholds, reduced CGT and dividend allowances, higher employer NI — it adds up. The employee NI cut helps, but for many it’s more than wiped out by fiscal drag pulling them into higher bands.

Frequently Asked Questions

Has the Personal Allowance changed for 2025/26?

No. Still frozen at £12,570, where it’s been since 2021/22. Not expected to move until at least April 2028. Meanwhile, wages keep rising, so more people are pulled into higher bands each year.

What is the National Insurance rate for 2025/26?

Employee NI: 8% on earnings between £12,570 and £50,270, 2% above that. Employer NI jumped to 15% from April 2025, with the threshold dropping to £5,000. That employer increase is the biggest tax change this year.

Has Capital Gains Tax gone up?

Yes. From October 2024, the lower rate went from 10% to 18% and the higher rate from 20% to 24% on most assets. Combined with the £3,000 annual exempt amount, CGT bills are noticeably higher.

What is fiscal drag?

When tax thresholds are frozen but wages and prices keep rising. Without changing a single rate, more of your income falls into higher bands each year. It’s a hidden tax increase — and it’s been running since 2021.

When does the Personal Allowance unfreeze?

The current freeze runs until April 2028. Whether it’s extended or thresholds finally rise with inflation depends on whoever’s in charge and the state of the public finances at that point.
