Dividend Tax Rate Rise 2026/27: What the 2pp Increase Costs a Real Portfolio
A worked example showing exactly how much extra tax the 2026/27 two-percentage-point dividend tax rise costs an investor holding shares outside an ISA.
What actually changed
From 6 April 2026, dividend tax rates rose by two percentage points at both the basic and higher rate levels: the basic rate moved from 8.75% to 10.75%, and the higher rate from 33.75% to 35.75%. The additional rate, paid by top earners, stayed unchanged at 39.35%. This applies to dividend income above the £500 tax-free dividend allowance, received on shares held outside an ISA.

Taxable dividends after the £500 allowance: £4,500. At the previous 8.75% rate, tax due would have been £393.75. At the new 10.75% rate, tax due is £483.75 — an extra £90 a year on identical dividend income, purely from the rate change.
Worked example: higher-rate investor with £10,000 dividends
Taxable dividends after the £500 allowance: £9,500. At the previous 33.75% rate, tax due would have been £3,206.25. At the new 35.75% rate, tax due is £3,396.25 — an extra £190 a year from the rate rise alone.
The ISA shelter matters more now
Because dividends earned within a Stocks and Shares ISA remain entirely free of dividend tax regardless of rate changes, the 2026/27 increase strengthens the case for prioritising ISA allowance use for dividend-paying shares over holding them in a general investment account, where both the shrunk £500 allowance and the higher rates now apply.

The 2026/27 two-percentage-point dividend tax rise adds a modest but real cost for investors holding dividend-paying shares outside an ISA — £90 a year for a basic-rate investor with £5,000 of dividends, £190 a year for a higher-rate investor with £10,000. Using the annual ISA allowance to shelter dividend income remains the most direct way to avoid both this rise and the reduced £500 allowance entirely.

Frequently asked questions
What changed with dividend tax rates in 2026/27?
The basic rate on dividends rose from 8.75% to 10.75%, and the higher rate rose from 33.75% to 35.75% — a two-percentage-point increase at both levels, from 6 April 2026. The additional rate stayed at 39.35%.
What is the dividend allowance for 2026/27?
£500 — the first £500 of dividend income each tax year is tax-free regardless of which Income Tax band the dividends otherwise fall into, though this allowance has been reduced substantially in recent years from a previous £2,000 and £5,000 level.
How much extra tax does the 2pp rise cost a basic-rate investor with £5,000 of dividends?
Taxable dividends after the £500 allowance are £4,500. At the old 8.75% rate this would have been £393.75; at the new 10.75% rate it is £483.75 — an extra £90 a year purely from the rate change on the same dividend income.
Does the dividend tax rise affect dividends earned inside an ISA?
No — dividends received on shares held within a Stocks and Shares ISA remain completely free of dividend tax regardless of rate changes, which is exactly why the rise increases the incentive to use ISA allowances fully before holding dividend-paying shares in a general investment account.
How much extra does a higher-rate taxpayer with £10,000 of dividends pay?
Taxable dividends after the £500 allowance are £9,500. At the old 33.75% rate this would have been £3,206.25; at the new 35.75% rate it is £3,396.25 — an extra £190 a year from the rate rise alone.
Should investors move dividend-paying shares into an ISA to avoid the increase?
Using the £20,000 annual ISA allowance to hold dividend-paying shares is one of the most direct ways to shelter future dividend income from both the rate rise and the shrunk £500 allowance, subject to each year's ISA contribution limit and any capital gains tax implications of moving existing holdings.
