The number of people who have to pay dividend tax in the UK is set to reach a record 3.7 million in the tax year 2024/25, according to new figures. Cuts to the dividend tax allowance over recent years have been slowly attracting more taxpayers into its net, with around 1.3 million more people expected to be caught by it in just two years.
Dividend tax is charged on income from dividends, different from capital gains tax, which is charged on profits from selling investments. For the 2024/25 tax year, the rates are still 8.75% for basic rate payers, 33.75% for higher rate payers, and 39.35% for additional rate payers.
Continuous Erosion of the Tax-Free Allowance
Only eight years ago, dividends over £5,000 were taxed. That was reduced in 2017/18 to £2,000, subsequently cut to £1,000 in 2023, and then reduced again to £500 from April 2024. As a result, many more people have been subject to tax on even modest investment income.
Recent HMRC statistics show that the dividend taxpayers increased from 1.9 million in 2022/23 to 3.08 million in 2023/24. This is forecast to increase again for 2024/25 to 3.67 million. The April 2024 reduction alone will add an additional 480,000 taxpayers to the net in addition to the 865,000 added last year.

Impact on Government Revenue
The shrinking dividend allowance is just one aspect of a broader trend of "stealth taxes," where freezing or reducing thresholds increases the level of tax paid without raising official rates. HMRC puts the April 2024 cut at £450 million in 2024/25, rising to £940 million by 2027/28.
Furthermore, dividend tax receipts are also expected to reach £18.6 billion in 2025/26. Experts note, however, that the growing taxpayer base comes with increased complexity, especially for those that are new to tax reporting.
Who's Paying Dividend Tax Now?
What was once a tax that mainly fell on the high earners and business owners now falls on a much larger group of people. 1.1 million basic rate taxpayers will be paying dividend tax in 2024/25, many of whom will be paying for the first time. Others may have only small investments outside ISAs or pensions, so the new changes are an unwelcomed surprise.
Nearly 20% of higher rate payers will be forced to pay an average of £6,202, and the additional rate payers will be forced to pay an average of £28,879. This adjustment signals the expansion of the levy to the middle-income families and the higher slabs.
Will the Allowance Disappear Completely?
There has been speculation about potential changes to dividend tax, including an earlier leaked Treasury memo that suggested the abolition of the remaining £500 allowance. This would raise only a limited extra amount of revenue, but may be on the cards if the government is eager to extract maximum revenue from every available source.
However, based on some financial experts, abolition of the allowance in its entirety could deter investment in the UK economy, which remains highly attractive to investors looking for dividends. While no immediate changes are expected with the Autumn Budget approaching, the possibility remains open.
Shielding Investments from Dividend Tax
Investors can shield their income from dividend tax by making use of tax-efficient investment structures. Stocks and shares ISAs, which have a £20,000 annual limit, allow dividends and capital gains to be generated tax-free. Pensions, like SIPPs, also offer protection, allowing for dividends to be saved without affecting the allowance.
Other options are Venture Capital Trusts (VCTs), exempt from dividend tax and offering up to 30% advance income tax relief, but typically of greater investment risk. Couples can also reduce their liabilities by splitting income-producing assets between the couple to take advantage of both allowances and lower rates of tax.
Conclusion
The sharp reduction in the dividend tax allowance has extended the scope of the charge to millions of extra taxpayers, with basic rate investors hit especially hard. While the reforms have significantly boosted the revenue for the government, they also created extra layers of complexity for those navigating through the system for the first-time.
For those who are hit, careful use of ISAs, pensions, and other tax-efficient plans can help reduce liabilities, safeguard returns, and leave taxation straightforward. With the fiscal pressures continuing, investors may have to watch out for further policy changes that could affect their income.
