Every April, the UK tax landscape shifts — and 2026 will be no exception.
Even when the government promises “no new taxes,” frozen thresholds quietly shrink your take-home pay.
Here’s what’s really changing — and how to adjust your budget so these small policy tweaks don’t undo your progress.
1. Income Tax Thresholds Are Frozen — What That Means
The Personal Allowance (£12,570) and Basic Rate threshold (£50,270) remain frozen through 2026.
When your salary increases but thresholds don’t, more of your income slips into higher tax brackets — a hidden effect known as fiscal drag.
Example:
- 2025 salary: £35,000 → take-home pay ~£27,520
- 2026 salary: £36,750 (5% rise) → take-home pay ~£28,495
- Gain: +£975 gross
- Real gain after tax & NI: ~£690
- Inflation-adjusted: ~£300 (2–3% feel-good factor only)
🧮 You earn more, but your disposable income barely improves.

2. National Insurance Cuts: A Small Win
The government is considering a 1% NI cut, reducing employee contributions from 8% to 7%.
That saves around £350/year for a £35k earner.
💡 Budget move: redirect that “win” straight into your Emergency Fund or ISA, not everyday spending — it’s easy to lose track of it otherwise.
3. Savings & ISA Rules — A Quiet Opportunity
The ISA allowance (£20,000) will likely remain frozen.
However, more banks will offer Flexible ISAs, allowing you to withdraw and redeposit funds in the same tax year.
This gives savers flexibility to handle short-term cash flow issues without losing tax benefits.
Use this to:
- Park sinking funds (holiday, car, home repairs) inside your ISA.
- Top up before April each year to use your full allowance.

4. Child Benefit & Pension Adjustments
- The High-Income Child Benefit Charge threshold may increase slightly to £52,000.
- The Pension Annual Allowance (£60,000) remains — allowing for salary sacrifice or extra contributions.
If your income creeps near £50–55k, consider increasing pension contributions to reduce your tax exposure and preserve your benefits.
5. The Big Picture in Numbers
| Category | 2025 | 2026 (Projected) | Budget Impact |
|---|---|---|---|
| Personal Allowance | £12,570 | £12,570 (frozen) | More pay taxed |
| Basic Rate Limit | £50,270 | £50,270 (frozen) | Fiscal drag on raises |
| Employee NI | 8% | 7% (cut) | ~£350/year saved |
| ISA Allowance | £20,000 | £20,000 (frozen) | No new tax-free room |
| Inflation (CPI) | ~4% | ~3% | Modest relief |
| Energy Cap (avg.) | £2,074 | £2,200+ | +£126/year |
| Child Benefit Threshold | £50,000 | £52,000 (est.) | Slight gain for families |
💡 Example: The “Hidden Loss” Effect
Let’s put it into perspective for a middle-income household:
| Household | 2025 Disposable Income | 2026 Disposable Income (Est.) | Real Impact |
|---|---|---|---|
| Single, £35k salary | £27,520 | £28,495 | +£975 gross → ~£300 real gain |
| Couple, £60k + £30k | £55,600 | £56,800 | +£1,200 gross → ~£500 real gain |
| Family (2 kids, £45k) | £36,900 | £37,700 | +£800 gross → £0 gain after cost increases |
🧩 Bottom line: Most households will feel neutral or slightly worse off, even with small wage rises.
6. How to Adjust Your 2026 Budget
To protect your finances before April:
- Add a 3% inflation buffer to food, energy, and transport categories.
- Increase your Emergency Fund goal by £300.
- Update your take-home pay in your tracker — use the latest HMRC calculator.
- Plan pension or ISA top-ups to shield more income from tax.
- Don’t wait for policy changes — they rarely improve your day-to-day budget immediately.
Takeaway
Tax policy may look neutral on paper — but frozen thresholds and creeping costs mean your 2026 budget will need tightening.
You can’t control the tax code, but you can control your numbers.
Track your real spending, recalculate your categories, and let your budget work like a personal inflation shield.
