Why we’re bringing our clients a tax investigation service

Why we’re bringing our clients a tax investigation service

When you run a business, the last thing you want is an unexpected tax investigation eating up your time and money.

HM Revenue & Customs (HMRC) enquiries can be stressful and costly, even when you’ve done everything right and it’s a genuine error on their part.

That’s why we are partnering with Markel Tax, who work with over 2,500 accountancy practices and are specialists in handling HMRC enquiries.

What is a tax investigation service?

A tax investigation service gives you expert, controlled support and representation if HMRC decides to review your tax affairs.

If HMRC launches a full enquiry, an aspect enquiry, a compliance check, or an intervention, your accountant must use their technical expertise and invest significant time resolving it.

This may involve compiling detailed records, producing supporting documentation, liaising with HMRC officers, and potentially attending meetings on your behalf.

A dedicated tax investigation service means those professional activities are handled quickly and efficiently by experienced specialists, so you don’t have to shoulder the operational burden alone.

Why is a tax investigation service so valuable to our clients?

Even businesses with accurate, timely, and fully compliant accounts can find themselves under scrutiny.

HMRC sometimes selects cases randomly, uses advanced data analytics to flag potential discrepancies, or may act on third-party information.

Regardless of the trigger, investigations can be time-consuming and disruptive and without specialist support, you could face delays, stress and additional cost just to prove your compliance.

Some of the key benefits include:

  • Immediate response to any HMRC contact, avoiding delays.
  • Thorough preparation and representation, increasing the chance of a quicker, positive resolution.
  • Access to specialist advice on complex areas such as VAT, PAYE, IR35, and Corporation Tax.
  • Peace of mind knowing experienced professionals are managing the process on your behalf.

Essentially, a tax investigation service ensures that we, as accountants, can focus fully on protecting your position, without you worrying about the operational and technical load.

Why Markel Tax?

By partnering with Markel Tax, your accountant is giving you access to a team experienced in dealing with HMRC enquiries and the technicalities of tax law and investigation procedures.

Their service typically includes:

  • Representation for full and aspect enquiries, compliance checks, and VAT/PAYE visits.
  • Support for interventions, such as checks on directors’ personal tax returns when linked to the business.
  • Access to specialist tax consultants and expert opinions to strengthen your defence.
  • Clear, transparent engagement terms so you know exactly what support you’ll receive.

Investigations can range from simple queries to complex cases involving multiple years of accounts.

Without structured support, defending these could cost time and distract you from running your business.

With Markel Tax’s service in place, we can dedicate the right level of resource and technical expertise to your case without hesitation.

This ensures nothing is overlooked and your interests are fully protected.

It’s also worth noting that offering this service does not encourage HMRC scrutiny or imply any wrongdoing.

Instead, it provides a professional, proactive safeguard because we value risk management and care deeply about our clients.

A smart safety net for your business

A tax investigation service is a strategic safety net that keeps you protected and helps your accountant work efficiently if HMRC comes calling.

Partnering with an accountancy firm (like Delphini) who offer this through Markel Tax shows they are committed to safeguarding your time, money and peace of mind.
