When you invest in the stock market, you make money in two ways: dividends and capital gains.
However, the critical part is that both are taxed differently in the UK.
If you’re an investor or planning to become one, you need to know how this affects your returns. In this blog, we’ll break it down clearly—no complicated terms or long-winded explanations—just straight answers.
By the end, you’ll understand how to keep more of your investment income and make more intelligent choices.
What Are Dividends?
Dividends are payments made by companies to shareholders from their profits.
Suppose you own shares in a company that performs well. In that case, you may receive a portion of their profits, typically on a quarterly or annual basis.
You get this income even if you don’t sell your shares.
What Are Capital Gains?
Capital gains happen when you sell your shares for more than you paid.
For example:
- Buy stock at £500
- Sell it at £800
- Your capital gain = £300
This Profit is taxed differently from dividend income.
How Is Dividend Income Taxed in the UK?
1. Tax-Free Allowance
As of the 2025–26 tax year, the dividend allowance is £500 per year.
This means the first £500 of dividend income is tax-free.
2. Tax Rates After Allowance
Once you go over the £500 allowance, you pay tax based on your income tax band:
Income Tax Band Dividend Tax Rate
Basic Rate (up to £50,270) 8.75%
Higher Rate (£50,271–£125,140) 33.75%
Additional Rate (Over £125,140) 39.35%
Your broker usually doesn’t deduct this automatically. You’ll need to report it through self-assessment if it exceeds your allowance.
How Are Capital Gains Taxed in the UK?
1. Capital Gains Tax (CGT) Allowance
For the 2025–26 tax year, the annual CGT allowance is £3,000.
Any profit under this amount is tax-free.
2. Tax Rates on Gains
If your capital gains go over the £3,000 limit, here’s what you pay:
Income Tax Band Capital Gains Tax Rate
Introductory Rate 10% on most assets
Higher/Additional Rate 20% on most assets
Property gains may be taxed at a higher rate, but we’re focusing here on stock investments.
Which One Is Better—Dividends or Capital Gains?
It depends on your income level and strategy.
Dividends Are Great If You Want:
- Regular income
- Passive cash flow
- Income without selling your stocks
However, dividend income is taxed sooner, even if you don’t sell any shares.
Capital Gains Are Better If You Want:
- To let your money grow over time
- Pay tax only when you sell
- More control over when you pay tax
Capital gains let you plan when to sell, so you control when you pay tax.
Tax Efficiency Tip: Use a Stocks and Shares ISA
Any investments inside an ISA are entirely tax-free.
That means:
- No dividend tax
- No capital gains tax
- No need to report to HMRC
This is one of the best tools for long-term, tax-efficient investing in the UK.
When and Where Is Tax Paid?
You pay tax through Self-Assessment if:
- Your dividend income exceeds the £500 allowance
- Your capital gains exceed £3,000
- You’re in the higher tax band
You submit your tax return to HMRC, usually online. Payment is due by 31 January each year for the previous tax year.
What’s the Venue for Stock Trading?
Most UK stock trading takes place digitally through the London Stock Exchange (LSE), located in Paternoster Square, London.
- Trading Hours: Monday to Friday
- Time: 8:00 AM to 4:30 PM
- Closed on public holidays
Even though everything happens online, this is the heart of UK financial trading.
Nearby Stays If Visiting the LSE
For finance fans or business travellers:
- Hotels nearby: The Ned, Club Quarters St. Paul’s, Apex Temple Court

Great spot to feel the pulse of UK finance, even if you’re just curious.
Common Mistakes Investors Make
- Ignoring dividend tax: Even small payments count towards your allowance
- Not planning capital gains: Selling too much at once can push you into a higher tax band
- Skipping ISA accounts: Missing out on tax-free growth
- Not reporting income: You still owe tax, even if your broker doesn’t deduct it
Avoid these early on to keep more of your profits.
