From April 2026, UK dividend tax rates rise, the personal allowance and other thresholds stay frozen through April 2030, and the state pension increases 4.8%. None of these on their own is a dramatic single headline — but together, and layered on top of a bigger Cash ISA change already confirmed for 2027, they add up to a meaningfully different picture for savers and investors than "no new taxes" might suggest.
The short version: dividend tax rates go up (basic rate 8.75%→10.75%, higher rate 33.75%→35.75%) from April 2026. The personal allowance stays frozen at £12,570 through 2030, quietly pulling more income into tax each year as wages rise. The state pension rises 4.8%. The widely-discussed Cash ISA cut to £12,000 doesn't hit until April 2027 — for 2026, the full £20,000 ISA allowance still applies.
Fiscal drag: the tax rise that isn't a rate change
The personal allowance (£12,570) and the higher-rate threshold have been frozen for years, and that freeze now extends to April 2030. Freezing a threshold while wages and prices keep rising is sometimes called a "stealth" tax rise: each pay increase pushes more income past a threshold that hasn't moved, so more of it gets taxed, and more people cross into the higher band — without the government ever announcing a headline rate increase. Over a multi-year freeze, this consistently raises more revenue than a single rate change would, precisely because it's less visible.
Dividend tax rates are going up
From April 2026, dividend income taxed outside an ISA or pension sees its rate rise: the basic-rate band moves from 8.75% to 10.75%, and the higher-rate band from 33.75% to 35.75%. The £500 tax-free dividend allowance is unchanged. This only affects dividend income above that allowance and held outside tax-sheltered accounts — if your dividend-paying investments already sit inside an ISA, this specific change doesn't touch you.
| Scenario | Tax at old rate | Tax at new rate (from April 2026) |
|---|---|---|
| £5,000 dividend income, basic rate | £393.75 | £483.75 |
| £10,000 dividend income, higher rate | £3,206.25 | £3,396.25 |
That's £90 more a year on £5,000 of basic-rate dividend income, and £190 more on £10,000 of higher-rate dividend income — modest per pound, but a real, permanent increase in the ongoing cost of holding dividend-paying investments outside a tax-sheltered account.
What's happening to ISAs — this year versus next
The headline "Cash ISA cut" that's been widely discussed doesn't take effect in 2026. From April 2027, the Cash ISA allowance for under-65s drops from £20,000 to £12,000, while the Stocks and Shares and Innovative Finance ISA allowance stays at £20,000, and over-65s keep the higher £20,000 Cash ISA limit. For April 2026 specifically, nothing changes yet: the full £20,000 adult ISA allowance resets as normal, with the £4,000 Lifetime ISA allowance counted as part of that total, not on top of it.
The state pension is rising 4.8%
The state pension increases 4.8% from April 2026, confirmed in the budget. For pensioners relying mainly on the state pension with little other taxable income, this is a straightforward income increase. It's a separate, unrelated change from the dividend and allowance changes above — a household can see the pension increase and the fiscal-drag effect simultaneously if it has both state pension and other taxed income.
Smaller changes worth knowing
- Venture Capital Trust (VCT) relief: income tax relief on VCT investments drops from 30% to 20%.
- Capital Gains Tax on Business Asset Disposal Relief: rises from 14% to 18% on qualifying disposals.
- Alcohol duty, council tax, car tax, and air passenger duty all rise at various points in the year — general cost-of-living increases rather than investment-specific changes.
What this means for your planning
- Hold dividend-paying investments outside an ISA? Moving them inside an ISA (within your annual allowance) shelters future dividend income from this specific rate rise entirely.
- Getting a raise this year? Check where it lands relative to the frozen thresholds — a raise that looks like a raise on paper can be partly or mostly absorbed by moving into a higher effective tax rate.
- Planning around the 2027 ISA change already: there's a full year of runway before the Cash ISA cut hits — no need to rush a decision in 2026 because of it.
