If you have received an HMRC dividend income nudge letter, do not ignore it. HMRC uses ‘one-to-many’ campaigns and third-party data to prompt taxpayers to review possible inaccuracies. Where it finds a mismatch, it sends a nudge letter to the shareholder involved, giving them an opportunity to put things right before a formal compliance check begins. Acting quickly and correctly is the single most effective way to reduce any penalty you might face.
This guide explains why HMRC sends these letters, what information they are working from, what your current tax obligations are for dividend income, and the exact steps you should take right now.
Who Is Most at Risk of Receiving This Letter?
A particular area of focus is owner-managed businesses, where directors may pay themselves a small salary and supplement it with dividends. While this is a common and tax-efficient strategy, failing to declare these dividends accurately can raise red flags.
Other risk groups include:
- Sole directors of small, limited companies
- Family-run businesses where multiple shareholders receive dividends
- SMEs that pay dividends informally, without proper board minutes or dividend vouchers
Your Dividend Tax Obligations: The Current Rules
Before deciding how to respond, it helps to be clear on what the rules say.
The Dividend Allowance for 2025/26
The dividend allowance for 2025/26 is £500. Dividend income is only taxed once it exceeds the dividend allowance and any available Personal Allowance. Only the portion above these allowances is subject to dividend tax. This allowance has fallen sharply in recent years. It was £2,000 for 2022/23, dropped to £1,000 for 2023/24, and dropped to £500 for 2024/25, thus bringing many more taxpayers into the requirement to declare dividend income.
Important:
If you already file a Self-Assessment tax return, you must report dividend income on it. But if your dividends are within the dividend allowance for the tax year, HMRC says you do not need to tell HMRC solely for that reason. Dividend Tax Rates for 2025/26
For 2025/26, dividend tax rates are 8.75%, 33.75% and 39.35%, but the rate applied depends on how the dividend sits within your taxable income bands after allowances. One taxpayer can pay dividend tax at more than one rate. Higher rate taxpayers with income between £50,271 and £125,140 pay 33.75% in 2025/26. Additional rate taxpayers with income over £125,140 pay 39.35%.
At Budget 2025, the government announced legislation to increase the dividend ordinary rate from 8.75% to 10.75% and the dividend upper rate from 33.75% to 35.75% from 6 April 2026. As of 18 March 2026, this is best described as an announced legislative change rather than a current rate already in force.
A Practical Example:
Suppose you are a company director who paid yourself a salary of £12,570 and took dividends of £20,000 in the 2024/25 tax year but only declared £5,000 of those dividends on your Self-Assessment return.
Your undeclared dividend income is £15,000. After applying the £500 allowance (already used), £15,000 would be taxed at the basic rate of 8.75%, giving an additional liability of £1,312.50, before interest and penalties are added. If HMRC identifies this through a formal enquiry rather than through your own voluntary disclosure, penalties will be significantly higher.
What Happens If You Ignore the HMRC Dividend Income Nudge Letter?
Ignoring the letter is the worst option available to you. Failure to respond to any letters received altogether could result in HMRC initiating an unwanted compliance check, leading to the possibility of higher penalties if undeclared dividend income is discovered as a result.
For income tax, the ordinary assessment time limit is generally 4 years, it can be 6 years where the loss of tax was brought about carelessly, and 20 years where it was deliberate or in certain other cases. Offshore cases can have different extended limits.
The distinction between a voluntary disclosure (which you initiate) and a prompted disclosure (which happens after HMRC contacts you formally) matters greatly for penalties. Where there are tax irregularities that require correcting, being proactive is the best thing you can do. Unprompted disclosures can attract lower penalties than prompted disclosures. But once HMRC has sent you a nudge letter about the issue, you should not assume any later disclosure will still count as ‘unprompted’ for penalty purposes.
Step-by-Step: What to Do After Receiving a Dividend Nudge Letter
Step 1 - Do Not Panic, Follow the deadline stated in your actual HMRC letter
The letter gives you 30 days to respond. Use this time wisely. Gather your company's dividend records, board minutes, and dividend vouchers for the relevant tax years. Pull up your Self-Assessment returns for the same periods.
Step 2 - Compare Your Dividend Records Against Your Tax Returns
Check whether all dividends paid by the company appear on your personal tax returns. Look at:
- The total dividends declared by the company in its accounts
- The dividends shown on your personal Self-Assessment returns
- Any dividends paid to other shareholders (such as a spouse or family member) and whether those were declared on their returns
Step 3 - Decide How to Respond
You have two possible positions.
If you have no additional income to declare:
If the recipient believes they have no additional income to declare, they can advise HMRC of this via the telephone number or e-mail address provided in the letter. Do this in writing and keep a record of your response.
If you do have additional dividend income to declare:
You need to make a disclosure. Do not wait. Acting promptly can still help limit the scope of the issue and demonstrate cooperation, but once HMRC has contacted you, you should not assume any later disclosure will be treated as unprompted for penalty purposes
Step 4 - Use the HMRC Digital Disclosure Service
If you have undeclared dividend income from earlier tax years, you may be able to use HMRC’s Digital Disclosure Service. First, notify HMRC that you intend to make a disclosure. HMRC will then issue a Disclosure Reference Number and a Payment Reference Number. You must submit your disclosure within 90 days of HMRC’s acknowledgement and pay what you owe when you submit it. Before using the service, check whether HMRC has directed you to a different disclosure route in the letter.
Step 5 - Calculate What You Owe
Your disclosure should cover tax, interest, and penalties for every year where there has been an under declaration. HMRC provides calculators for interest and penalties, but its own guidance says those calculators will not calculate the underlying Income Tax due.
By coming forward now, making a complete disclosure, and gaining full abatements for telling, helping, and giving, there may be an appropriate reduction in any penalty that may be charged.
Step 6 - Consider Taking Professional Advice
This is the point at which involving a qualified tax adviser or accountant is strongly recommended. An adviser can:
Review all relevant tax years and identify the full extent of any under declaration
Calculate the correct liability, interest, and potential penalties
Draft and submit the DDS disclosure on your behalf
Negotiate with HMRC where appropriate
Disclosure Checklist: Before You Respond to HMRC
Use this checklist to make sure you have covered everything before submitting your response or disclosure.
Gathering Your Records
- Company accounts and dividend declarations for all relevant tax years
- Board meeting minutes approving dividend payments
- Dividend vouchers issued to shareholders
- Personal Self-Assessment returns for the same years
- Bank statements showing dividend payments received
Checking Your Returns
- Confirm whether all dividends received appear on your Self-Assessment returns
- Check whether the correct dividend allowance was applied in each year (£2,000 for 2022/23, £1,000 for 2023/24, £500 from 2024/25 onwards)
- Check whether any other shareholders in the family also need to review their returns
Acting
- Respond to HMRC within the 30-day window, even if only to say you are reviewing your position
- Register for the Digital Disclosure Service on GOV.UK if you have income to declare
- Seek professional advice before submitting your disclosure
- Submit the disclosure within 90 days of HMRC acknowledging your notification and pay what you owe when you submit it, using the payment reference number
Conclusion: Key Takeaways and Next Steps
Receiving an HMRC dividend income nudge letter is serious, but it does not by itself mean that a formal compliance check has started. Review your dividend records against your Self-Assessment returns, follow the deadline stated in the letter, and use the appropriate HMRC disclosure route if any income has been omitted. If you use the Digital Disclosure Service, HMRC says your disclosure must be submitted within 90 days of its acknowledgement of your notification.
Doing nothing increases the risk of further HMRC action. Acting quickly and making a full and accurate disclosure can help reduce penalties, but once HMRC has contacted you, you should not assume any disclosure will be treated as unprompted. Depending on the circumstances, HMRC may be able to assess earlier years beyond the normal time limit, including up to 20 years in deliberate cases.
FAQs:
Yes. If you missed dividend income, you should correct your Self-Assessment return. You can amend it within 12 months of the filing deadline, and after that you must contact HMRC to report the error.
HMRC uses data from tax returns, company filings, and other sources to identify inconsistencies. It does not rely on a single trigger but looks for patterns that suggest income may not have been fully declared.
Penalties depend on behaviour and can range from 0% to 100% of the tax. They are reduced if you disclose the error, cooperate, and provide accurate information.
Dividends must be paid from retained profits and properly declared. Companies are expected to keep records such as board minutes and dividend vouchers. Without proper evidence, HMRC may question how the payment should be taxed.
HMRC charges interest on late-paid tax from the original due date until payment. This is separate from penalties and cannot be reduced.
