Dividend Tax and ISAs 2026/27

Written by James Whitfield · Updated August 2026 · Checked against 2026/27 HMRC rates

An ISA is the cleanest way to take dividend tax off the table entirely. Dividends inside the wrapper aren't taxed and don't touch your £500 allowance1; the same dividends outside it get the £500 allowance and then 10.75%, 35.75% or 39.35%2. Here's the difference in pounds, plus the Bed and ISA move that shifts existing holdings across.

Key takeaways
  • Dividends inside a Stocks and Shares ISA are fully exempt from income tax1 and never reported.
  • ISA dividends don't use your £500 allowance2 — it stays free for holdings outside the wrapper.
  • The 2026/27 ISA subscription limit is £20,000 per person1; a couple can shelter £40,000 a year.
  • Outside an ISA, the same dividends are taxed at 10.75% / 35.75% / 39.35%2 by band.
  • "Bed and ISA" moves existing holdings inside — but the sale can trigger Capital Gains Tax, so check first.

No dividend tax inside an ISA

Dividends inside a Stocks and Shares ISA are completely exempt from UK income tax. It doesn't matter how large they are, what rate band you're in, or how much you receive — ISA dividends are simply not taxable.

The exemption covers individual company dividends, fund distributions, REIT distributions and interest distributions. Capital gains inside an ISA are also exempt from CGT. None of it needs to be declared on a Self Assessment return.

The ISA allowance: £20,000 per year

The ISA allowance for 2026/27 is £20,000 per person. You can split that across a Cash ISA, Stocks and Shares ISA, Innovative Finance ISA or Lifetime ISA (up to £4,000 into a LISA), but the combined total can't exceed £20,000.

Unused allowance doesn't carry forward. It resets on 6 April. But existing ISA funds — and all the dividends accumulated over previous years — stay sheltered indefinitely. There is no cap on the total pot size.

How the dividend allowance interacts with ISAs

ISA dividends are ignored by the UK tax system entirely. They don't count toward your £500 allowance and don't push you into a higher band. Your £500 remains fully available for anything held outside the ISA.

For investors with large dividend-paying portfolios this matters a lot. A £200,000 portfolio inside an ISA yielding 4% produces £8,000 in dividends — all tax-free. The same portfolio outside an ISA generates a real dividend tax bill, especially for higher and additional-rate taxpayers.

Worked example: ISA vs outside ISA

Scenario: £2,000 of dividends inside a Stocks and Shares ISA and £2,000 of dividends outside the ISA. Taxpayer has a salary of £30,000 (basic-rate taxpayer).

  • £2,000 ISA dividends — completely tax-free. No tax owed. The £500 dividend allowance is not used up by these dividends.
  • £2,000 outside-ISA dividends — £500 dividend allowance applies. Remaining taxable dividends: £1,500.
  • Salary of £30,000 is in the basic-rate band. Dividends fall in the basic-rate band too.
  • Dividend tax: £1,500 × 10.75% = £161.25.
Inside ISA Outside ISA
Dividend income £2,000 £2,000
Dividend allowance used £0 £500
Taxable dividends £0 £1,500
Dividend tax owed £0 £161 (at 10.75%)

If the same taxpayer had a salary of £55,000, dividends outside the ISA would fall in the higher-rate band at 35.75% — tax on the £1,500 would be £536.

Bed and ISA: moving investments into an ISA

If you hold dividend-paying shares outside an ISA, a Bed and ISA is worth considering: sell outside the ISA and immediately repurchase inside. Future dividends and gains on those holdings then become tax-free.

The sale can trigger a CGT liability if the investment has grown, so check that before proceeding. You can move up to £20,000 per year this way. Spouses and civil partners each have their own £20,000 allowance, so a couple can shelter up to £40,000 per year.

Frequently asked questions

Do I pay tax on dividends in an ISA?
No. Dividends received inside a Stocks and Shares ISA are completely exempt from UK income tax. There is no dividend tax to pay on ISA dividends regardless of the amount or your tax rate, and you do not need to declare ISA income on a Self Assessment return.
Does the dividend allowance apply to ISA income?
No — ISA dividends are simply ignored for tax purposes entirely. They do not use up your £500 dividend allowance. Your £500 allowance remains fully available for any dividend income you hold outside an ISA. This is an additional benefit of holding investments inside an ISA.
Can I put unlimited amounts in an ISA to avoid dividend tax?
No. The ISA allowance is £20,000 per person per tax year in 2026/27. You cannot carry forward unused allowance from previous years. However, the allowance resets each 6 April and existing ISA funds remain sheltered indefinitely with no upper cap on the total pot size.
What is a Bed and ISA and is it worth doing?
Bed and ISA means selling shares you hold outside an ISA and immediately buying them back inside one, so future dividends and gains become tax-free. It's usually worth it for dividend-paying holdings, but the sale is a disposal for Capital Gains Tax, so a large gain could create a CGT bill. Most platforms run it as a single instruction to minimise time out of the market. You're limited to your £20,000 annual ISA subscription.
Do REIT and fund distributions inside an ISA stay tax-free?
Yes. Company dividends, fund distributions, REIT property income distributions and interest distributions are all exempt from tax inside an ISA, and none of it goes on a Self Assessment return. Outside an ISA some of these — REIT property income in particular — are taxed as ordinary income rather than at dividend rates, so the ISA shelter is often even more valuable for those holdings.
