Dividends and Self Assessment 2026/27
HMRC cannot automatically collect dividend tax through PAYE for most people. If your dividend income exceeds certain thresholds, you need to register for Self Assessment and declare it yourself. This guide explains when and how.
Published by the UK Money Calculators editorial team. Last updated for the 2026/27 tax year.
In 2026/27 you must tell HMRC about dividends over the £500 allowance. If your dividend income is over £10,000 you have to register for Self Assessment and file a tax return. Between £500 and £10,000 you can instead ask HMRC to collect the tax through your PAYE tax code. Dividends inside an ISA never need declaring.
When do dividends trigger Self Assessment?
Dividend income above the £500 allowance is taxable. HMRC guidance says you must register for Self Assessment if your dividend income is over £10,000 in a tax year; between £500 and £10,000 you can instead ask HMRC to collect the tax through your tax code.
Small dividends within the £500 allowance may not require registration if you have no other filing obligation. But thresholds can change. Check GOV.UK or ask a tax adviser to confirm the current position.
How dividend tax is estimated and paid
When you file, HMRC calculates dividend tax based on what you declare. Salary and other non-dividend income fills the Personal Allowance (£12,570) and rate bands first. Dividends sit on top.
The first £500 is covered by the dividend allowance at 0%. Above that: 10.75% basic rate, 35.75% higher rate or 39.35% additional rate depending on where your dividends land.
Worked example
Scenario: An employee earns £40,000 salary and receives £2,500 in dividends outside an ISA in 2026/27.
- Dividends of £2,500 exceed the £500 allowance, so £2,000 is taxable and must be reported to HMRC.
- Salary fills the Personal Allowance and sits in the basic-rate band.
- Dividends sit on top in the basic-rate band.
- First £500: dividend allowance — £0 tax.
- Remaining £2,000 at 10.75% = approximately £215.
- Total dividend tax to declare and pay: approximately £215.
This would be declared on the Self Assessment return for the 2026/27 tax year, due by 31 January 2028 for online returns.
How to declare dividend income on Self Assessment
Dividend income goes in two places on the return:
- Dividends from UK companies — UK-listed shares or your own company.
- Dividends from foreign companies — overseas shares, where withholding tax treaties may also apply.
Dividends inside an ISA or pension don't need to be reported. Only dividends outside those wrappers are taxable and reportable.
Records to keep
- Dividend vouchers from each company paying a dividend
- Annual statements from your broker or platform showing dividends received
- Dividend reinvestment confirmations (if applicable)
- For your own company: formal dividend vouchers and board minutes authorising each payment
