“I know I should have dealt with this sooner.”
It is one of the most common things people say when they first speak to us about a tax problem.
Sometimes, they have missed several tax returns. Sometimes, they owe HMRC more than they can afford to pay. In other cases, they forgot to declare income, misunderstood the tax treatment of an overseas asset or stopped opening letters because the situation felt overwhelming.
Whatever happened, many clients expect an accountant to criticise them.
That is not our role.
Our job is to understand the facts, explain the risks and help the client take the next appropriate step. We cannot change the past, but we can often make the future much more manageable.
Tax Problems Happen for Many Reasons
People rarely wake up one morning and decide that they would like a complicated problem with HMRC.
More often, the problem develops gradually.
A person may start working for themselves without fully understanding Self Assessment. A landlord may assume that tax only becomes relevant once a property makes a clear cash profit. Someone returning to the UK may misunderstand the residence rules. Meanwhile, a business owner may fall behind with VAT or PAYE during a difficult trading period.
Personal circumstances also matter. Bereavement, illness, divorce, caring responsibilities, job loss and business failure can quickly push tax administration to the bottom of the list.
One unanswered HMRC letter becomes three. Missing records become harder to reconstruct. The amount due may grow because of interest or penalties. Eventually, the client feels too embarrassed to ask for help.
We explored this pattern in our article on why clients sometimes wait years before seeking tax help. In many cases, the delay comes from fear rather than a lack of concern.
We Focus on the Facts, Not on Blame
When a client tells us about a tax problem, we need to establish what happened.
That normally means answering practical questions:
- Which tax years or accounting periods are affected?
- Were tax returns submitted?
- What income or transactions were omitted?
- Has HMRC already made contact?
- Are the available records complete?
- How much tax might be due?
- Can the client afford to pay it?
- Was the problem accidental, careless or deliberate?
These questions are not accusations. They help us understand the position and decide what work needs to happen next.
For example, a missed tax return requires a different response from an HMRC fraud investigation. An undeclared rental property may need different calculations from an overseas bank account. Likewise, a person who cannot pay an agreed liability faces a different problem from someone who does not yet know how much they owe.
Clear facts allow us to give useful advice. Judgement does not.
We Have Seen More Than Most Clients Expect
People often believe their situation is uniquely bad.
They may say:
“I have never told anyone about this.”
“You probably have not dealt with anything like it.”
“This must be the worst tax situation you have seen.”
Usually, it is not.
Tax advisers regularly work with late returns, missing records, undeclared income, HMRC enquiries, tax debts and misunderstandings that stretch back several years.
Although every case has its own details, the underlying problems are often familiar.
That experience helps us remain calm. It also allows us to separate a serious technical risk from something that merely feels frightening because the client has faced it alone.
Even where the position is serious, panic will not improve it. A structured review, accurate calculations and honest communication offer a much better starting point.
Honesty Helps Us Protect Your Position
Although we do not judge clients, we do need them to be open with us.
An accountant can only give reliable advice when the information is complete and accurate. If a client withholds an account, changes part of the story or provides only the documents they think look favourable, the adviser may reach the wrong conclusion.
That can create a bigger risk later—particularly if HMRC already holds information from another source.
For example, HMRC may receive data from employers, financial institutions, Companies House, overseas tax authorities and other third parties. It may also compare tax returns with information already held in its systems.
Therefore, it is much safer to tell your adviser about the difficult part at the beginning. The information that feels most embarrassing may be the information we need most.
If overseas matters are involved, our article explaining whether HMRC can access overseas banking information may help you understand why full disclosure matters.
Confidentiality Matters—but It Has Legal Limits
Clients should feel able to discuss sensitive financial matters privately with their accountant. Accountancy firms must handle personal data securely and follow professional and data-protection requirements.
However, confidentiality is not an agreement to hide wrongdoing.
Accountants must comply with UK anti-money laundering legislation and professional obligations. In certain circumstances, a regulated firm may need to submit a Suspicious Activity Report where it knows or suspects money laundering. Tax evasion can create criminal property for these purposes.
The law may also prevent the accountant from telling the client whether a report has been made.
This does not mean that every tax error creates a report. A genuine mistake, misunderstanding or late filing does not automatically amount to money laundering. The facts, the client’s knowledge and what happens after the problem comes to light all matter.
The important distinction is simple: we can help clients correct tax problems, make appropriate disclosures and deal with HMRC. We cannot help anybody conceal income, create false documents or give HMRC information that we know is misleading.
A good adviser combines understanding with professional honesty.
Coming Forward Can Improve the Position
Clients sometimes assume that admitting a problem will automatically make everything worse. As a result, they consider waiting to see whether HMRC discovers it.
That approach carries significant risk.
HMRC distinguishes between disclosures made before it prompts the taxpayer and those made after contact. Depending on the type of error and the relevant penalty rules, an unprompted disclosure may produce a better outcome than waiting for HMRC to start an enquiry.
HMRC may also consider the quality of the disclosure. This includes how much the taxpayer tells HMRC, how actively they help calculate the correct liability and whether they provide access to relevant records.
Of course, disclosure needs careful preparation. It should cover the correct taxes and periods, use reasonable calculations and explain the circumstances accurately.
If you believe you have undeclared income, our guide on how to disclose undeclared income to HMRC explains the general process.
Not Every Tax Problem Requires the Same Solution
The right approach depends on what has happened.
| Situation | Possible next step |
| A return contains an error | Check whether the return can still be amended or whether HMRC needs a separate disclosure |
| One or more returns are outstanding | Prepare and submit the missing returns, using reconstructed figures where appropriate |
| Income was never declared | Calculate the omitted income and use the correct HMRC disclosure route |
| HMRC has opened a compliance check | Review its questions, preserve the evidence and respond within the deadline |
| HMRC has issued an estimated bill | Check whether the assessment can be replaced or challenged using accurate information |
| The tax is correct but unaffordable | Review affordability and discuss payment options with HMRC |
| HMRC alleges deliberate behaviour | Seek specialist advice before responding |
Possible next step
- Check whether the return can still be amended or whether HMRC needs a separate disclosure.
- Prepare and submit the missing returns, using reconstructed figures where appropriate
- Calculate the omitted income and use the correct HMRC disclosure route
- Review its questions, preserve the evidence and respond within the deadline
- Check whether the assessment can be replaced or challenged using accurate information
- Review affordability and discuss payment options with HMRC
- Seek specialist advice before responding
This is why general advice from friends or online forums can be unhelpful. A solution that worked for somebody else may not fit your tax, your dates or your circumstances.
We Will Be Honest About the Risks
A non-judgemental approach does not mean pretending that nothing is wrong.
If interest is building, we will explain it. If HMRC may charge a penalty, we will discuss the likely basis. If a deadline creates an immediate risk, we will tell you.
Likewise, if the case requires legal advice or a specialist investigation service, we should say so.
Sometimes, the client’s position is better than they fear. At other times, the problem is serious and requires substantial work.
Either way, honest advice is more useful than reassurance that has no evidence behind it.
Progress Usually Begins with One Conversation
You do not need to have every document ready before contacting an accountant.
At the first stage, it is often enough to explain:
- what you believe has gone wrong;
- which years may be involved;
- whether HMRC has contacted you;
- what records you still hold; and
- whether you expect difficulty paying.
From there, the adviser can identify missing information and agree an order for the work.
The first conversation may not solve the whole problem. However, it replaces uncertainty with a plan—and that alone can make the situation feel much less overwhelming.
Practical Guide
Before speaking to an accountant about a tax problem:
- Collect HMRC correspondence. Include letters, notices, assessments and penalty documents.
- Write a short timeline. Note when the problem began and any important events.
- List the taxes and years involved. Do not worry if you are uncertain; approximate information still gives the adviser a starting point.
- Gather available records. These may include tax returns, accounts, payslips, invoices and bank statements.
- Identify missing information. Tell the adviser what you cannot currently find.
- Explain whether HMRC has contacted you. Provide the complete letter and the response deadline.
- Be open about affordability. If you cannot pay the expected liability in full, say so early.
- Tell the complete story. Do not leave out a fact because it feels embarrassing or unhelpful.
You do not need to present a perfect file. You simply need to give the adviser an honest place to begin.
Frequently Asked Questions
Will my accountant criticise me for filing late?
A professional accountant should focus on correcting the position and reducing further risk. They will need to ask why the filing was late, because the reason may affect penalties or a reasonable-excuse claim. However, that question should support the advice rather than assign blame.
Can an accountant keep my tax problem confidential?
Accountants must handle client information carefully and comply with professional and data-protection requirements. However, confidentiality has legal limits, including obligations under anti-money laundering legislation. An accountant cannot promise secrecy where the law requires action.
What if I do not have all my records?
Tell your accountant what is missing. They may help obtain copies or reconstruct figures using bank statements, invoices and other evidence. Avoid inventing amounts simply to fill gaps.
Will HMRC treat me more favourably if I come forward voluntarily?
An unprompted disclosure may qualify for a lower penalty range than a prompted disclosure, depending on the circumstances and relevant rules. HMRC may also consider how fully and helpfully you disclose the position. However, no adviser should guarantee a particular penalty outcome.
Can my accountant contact HMRC for me?
Yes, once HMRC has the appropriate authority in place. You will still remain responsible for your tax affairs, but your accountant can normally handle correspondence, explain calculations and discuss the case with HMRC.
Is it ever too late to ask for help?
You can still seek advice after HMRC has contacted you, issued penalties or started recovery action. However, your available options may narrow over time. Therefore, early advice usually gives you more control.
Where to Find Official HMRC Information
For current official guidance, see:
- Make a voluntary disclosure to HMRC, which explains the general disclosure process and the information HMRC may require.
- Tell HMRC about undeclared income, covering HMRC’s Digital Disclosure Service.
- Tax compliance checks, explaining what HMRC may check and what can happen during and after a compliance check.
- The HMRC Charter, which sets out the standards of behaviour taxpayers should expect from HMRC.
- Anti-money laundering supervision, which includes official guidance on the responsibilities of supervised accountancy firms.
- UK GDPR security guidance, published by the Information Commissioner’s Office.
Tax and disclosure rules depend on the facts. Therefore, check the current guidance and obtain advice before deciding which route to use.
