HMRC Enquiries, Compliance Checks & Disclosures

If HMRC has written to you, the first response shapes everything that follows. We take over the correspondence.

Who this is for

Anyone who has received an HMRC letter opening an enquiry, a compliance check or a nudge about undeclared income, as a company, employer, landlord or individual. Also those who know something was missed and want to come forward first, and those facing a penalty or tax demand they believe is wrong.

Compliance Checks & Enquiries

Corporation tax, income tax, VAT and PAYE enquiries handled end to end.

The letter will say what HMRC wants to look at and by when. We read it properly first, check whether the enquiry was opened in time and what it covers, and explain what it means in plain terms. From there we are the point of contact: replies are drafted by us, records are reviewed before anything is sent, and each request is answered in full but no wider than it needs to be. Compliance checks and enquiries end with a written position you understand before you agree to it.

Compliance Prompts & Nudge Letters

Assessing what HMRC actually knows and responding proportionately.

A compliance prompt or nudge letter is not an enquiry. It means HMRC holds data, from a letting agent, a bank, a platform or an overseas tax authority, and wants you to check your return against it. Some letters ask for a signed certificate of tax position; that should not be signed without a review, because the declaration carries consequences. We look at what the data might be, check the returns concerned, and either confirm there is nothing to correct or make the correction through the right route.

PAYE & Employer Compliance Reviews

Employer visits, status challenges and expenses and benefits reviews.

An employer compliance review starts with a request for a visit and a list of records: payroll, expenses claims, benefits, contractor invoices and CIS returns. Before the officer arrives we go through the same records ourselves, so you know where the exposures are before the meeting. We attend the visit, deal with questions on employment status, travel and subsistence, and directors' loans, and handle the follow-up correspondence. Where a PAYE and employer compliance review produces a liability, we check the years, interest and penalty position before anything is agreed.

02Coming forward first 1 area

Voluntary Disclosures

Digital Disclosure Service, Let Property Campaign and unprompted disclosures.

Coming forward before HMRC writes is treated differently from being found, in the penalty range and in the tone of what follows. A voluntary disclosure starts with quantifying what was missed, year by year, and deciding which route fits: the Let Property Campaign for rental income, the Digital Disclosure Service for most other income and gains, or a direct letter where the facts call for it. We register the disclosure, prepare the computation with the interest and penalty position explained, and submit it with the payment offer.

03Penalties and payment 3 areas

Penalty Appeals & Reasonable Excuse

Challenging late filing, late payment and inaccuracy penalties.

Penalty notices carry a time limit for appeal, and the first job is to protect it. We then look at the ground that fits: reasonable excuse for a late filing or payment, where illness, bereavement or a system failure is documented; a reduction for the quality of disclosure on an inaccuracy penalty; or special circumstances where the facts justify it. The appeal is written with the evidence attached, and if HMRC's decision stands we ask for an independent statutory review and, if needed, notify the tribunal.

Time to Pay Arrangements

Negotiating instalment arrangements and keeping enforcement away.

HMRC considers instalments where the proposal is realistic, the returns are up to date and the company or individual can show how the payments will be met. We prepare that case: a short cashflow, the affordability figures HMRC's debt management team ask for, and a proposal that is honest about what can be paid each month. We then make the call or the written application and confirm the terms in writing. Time to Pay arrangements are monitored afterwards, because a missed instalment can cancel the agreement.

ESC A19 & PAYE Underpayment Challenges

Contesting Simple Assessments and PAYE arrears where HMRC delayed acting on information held.

A P800 or Simple Assessment often follows a job change, a second pension or a benefit in kind that HMRC was told about but did not act on. ESC A19 allows a PAYE underpayment to be given up where HMRC held the information, failed to use it in time and it was reasonable for you to believe your affairs were in order. We reconstruct what HMRC was sent and when, from P45s, P60s, P11Ds and the employer's RTI submissions, and put the request in writing with that evidence.

04Escalation 1 area

Alternative Dispute Resolution & Tribunal Support

ADR applications and preparation of tribunal appeals, with counsel where required.

When correspondence has stalled, alternative dispute resolution puts an HMRC mediator between the two sides and can narrow or settle the issue without a hearing. We prepare the application, set out the facts and the points in dispute, and attend the mediation with you. Where the matter has to go to the First-tier Tribunal, we notify the appeal within the time limit, prepare the grounds, bundle and witness statements, and instruct tax counsel where the point of law justifies it, working alongside your solicitors if they are involved.

Questions

Frequently asked

What should I do first when HMRC writes to me?

Read the letter carefully, note the deadline it gives and do not reply or send documents until you understand what is being asked and why. Most letters are routine compliance checks or nudge letters rather than accusations, and a measured, accurate first response sets the tone for everything that follows. Send us the letter and we will explain what it means, agree the approach with you and take over the correspondence as your agent. Read more.

What is an HMRC nudge letter and do I have to respond?

A nudge letter is a prompt sent when HMRC holds information suggesting income or gains may not have been declared, for example from overseas banks, letting agents or online platforms, and it usually asks you to check your returns and sign a certificate. There is no legal duty to sign the certificate, but ignoring the letter is unwise. We establish what HMRC is likely to hold, check your position and respond proportionately. Read more.

Can I appeal an HMRC penalty for filing late?

Yes. Penalties for late filing, late payment and inaccuracies can be appealed, normally within thirty days of the penalty notice, where you have a reasonable excuse such as serious illness, bereavement or a failure in HMRC's own systems, or where the penalty has been calculated incorrectly. We set out the grounds with supporting evidence, submit the appeal and, if HMRC rejects it, request an independent review or take the matter to tribunal. Read more.

What happens if I cannot pay my tax bill on time?

Contact HMRC before the due date rather than after it, because a Time to Pay arrangement agreed in advance stops most enforcement action while it runs and can prevent late payment penalties on the amounts it covers. HMRC will want a realistic proposal supported by your income and outgoings, and it expects the instalments to be kept. We prepare the proposal, negotiate the arrangement and make sure future returns are filed on time so it holds. Read more.

Do I need to tell HMRC about undeclared rental income?

Yes. Undeclared income needs to be disclosed, and coming forward before HMRC contacts you is treated as unprompted, which means lower penalties than if HMRC finds it first. Landlords can use the Let Property Campaign, and other income and gains go through the Digital Disclosure Service. We calculate the tax, interest and penalty for each year, prepare the disclosure and handle the correspondence until it is settled. Read more.
