If you have received notice of a tax investigation from HMRC or you want advice about how best to prepare your tax affairs to prevent an investigation or to make one go as smoothly as possible, you can contact us. At Auditox Accountancy we can give you professional advice about all aspects of HMRC tax investigations.

What Triggers A Tax Investigation?

There are several reasons why an HMRC tax investigation may occur. Some of these are out of your control but others can relate to how you have completed your tax returns.

Random Investigations

HMRC will complete random checks. Every year, some businesses will be chosen at random to be investigated.

Type Of Business

Some types of businesses are deemed to be in a "high-risk industry". This means that the businesses in this industry are more likely than others to have tax issues. For example, businesses that deal mainly with cash payments rather than cards.

Inconsistencies In Tax Returns

HMRC has a Central Risk team. This team uses data mining tools to identify unusual activity in people's accounts. The type of activity they might pick up on will include:

  • a sudden large fall in income
  • inconsistencies in tax returns (for example small businesses that suddenly have a very large VAT claim)
  • a business that will frequently file tax returns late
  • a business whose tax records do not match norms for its industry

Tip-Offs

Occasionally, a tax investigation can be triggered by a tip-off. This is when an individual informs HMRC that they believe a person or company is committing tax fraud.

Different Types Of Investigation

There are three main types of HMRC tax investigations. The type of investigation you are under will determine what you can expect to happen.

Full Enquiry

This is also known as a "drains up" tax inspection. This is the most thorough type of investigation and occurs when HMRC has reason to believe that there is a significant risk of error in your accounts.

During a full enquiry, you can expect HMRC to investigate the entirety of your business records. This can include:

  • the tax you have paid
  • your accounts and tax calculations
  • your Self Assessment tax return and/or your Company Tax return
  • your VAT returns and your VAT records
  • your PAYE returns and your PAYE records

If you have a limited company, you can expect HMRC to also investigate the tax affairs of all company directors as well as the business taxes.

Aspect Enquiry

An aspect enquiry is less thorough than full enquiries. It is triggered when HMRC believes that there is an error with one part of your tax return. HMRC will investigate this one particular aspect of your accounts where there appear to be inconsistencies.

Random Enquiry

This is the type of enquiry that is part of HMRC's regular random tax investigations. The depth of the investigation will be at the discretion of the officer, depending on what they find.

What Types Of Taxes Does HMRC Investigate?

It is a common misconception that HMRC only investigates Income Tax. In fact, they also investigate:

  • Capital Gains Tax
  • Construction Industry Scheme (CIS)
  • Corporation Tax
  • Insurance Premium Tax
  • VAT
  • Landfill Tax
  • Climate Change Levy
  • IR35

What Are The Outcomes Of An HMRC Tax Investigation?

The outcome will depend on the information that HMRC has discovered during their investigation of your accounts. At the end of the investigation, you will receive a decision notice and/or a contract settlement.

Overpaid Tax

HMRC may discover that you have overpaid on your taxes. In this situation, you can expect them to issue a refund to you for the discrepancy.

Underpaid Tax

HMRC may also discover that you have not paid enough tax. In this situation, you can expect them to issue you a bill for the remaining tax that you need to pay.

Deliberate Or Negligent Wrongdoing

HMRC may determine that you have engaged in deliberate wrongdoing about your tax return. This can be a criminal investigation regarding tax fraud or tax evasion and is the most severe outcome.

The 5 Stages Of Tax Investigations

Every tax investigation is different depending on the type of tax audit and your circumstances. Generally speaking, however, the investigation will have five stages.

Stage 1 - Receipt Of Opening Letter

In the first stage, you will receive a letter from HMRC informing you that they will be conducting a tax audit. They will also lay out the information that they need from you. This could be expense receipts,

It is worth at this point checking that HMRC is within the time limit allowed to trigger the investigation in the first place. Tax inspections are under very strict rules about the time limits in which they can begin.

A tax inspector will have 12 months from when the return was filed. An HMRC investigation can only be opened after 12 months if the HMRC officers couldn't reasonably have known about the loss of tax at the time. For instance, if it had been deliberately concealed.

Stage 2 - Potential Further Correspondence

If you do not respond to the opening letter, you will receive more correspondence consisting of a formal request for the information and sometimes a penalty.

If you did respond to the opening letter, you may still receive further correspondence with clarifying questions and potentially a request for more information.

Stage 3 - Potential Face-To-Face Meeting Request

A face-to-face meeting can be requested either by you or by HMRC. Attending a meeting will demonstrate cooperation and can make the investigation more streamlined. You are welcome to bring along another person for moral support or to give you advice/take notes for you.

Before a face-to-face meeting, you can:

  • Request a copy of the agenda
  • Have a say in where the meeting is held
  • Request an estimate for how long the meeting is likely to take

Stage 4 - Face-To-Face Meeting

A face-to-face meeting can be daunting but you do have some control over the situation. The meeting is an information-gathering effort so being upfront and honest if you have made a genuine mistake will usually go down well.

During a meeting, you can:

  • Ask clarifying questions
  • Request that the meeting stick to the agenda laid out beforehand
  • Request that you be given time to look up information after the meeting before submitting an answer to a question
  • Ask for a break or for the meeting to end at any time

After a meeting, you can:

  • Request a copy of HMRC's notes from the meeting and submit any errors that you find in writing (this should be done sooner rather than later)
  • Sign the notes once you are happy that they are correct

Stage 6 - Closing The Investigation

As we have mentioned, there are three possible outcomes to the investigation:

  • Underpaid tax
  • Overpaid tax
  • Deliberate or negligent wrongdoing

If you are asked to sign a contract settlement, you will often be given a schedule of adjustments. This is the schedule on which HMRC proposes you make any necessary payments. Interest can be charged on penalties so it is worth looking into whether you can pay them off as a lump sum.

How Far Back HMRC Can Investigate

For routine tax audits that uncover nothing unusual, HMRC can't go back further than 12 months. However, HMRC can initiate a discovery assessment if:

  • The loss of tax was brought about carelessly or deliberately
  • Or the officers couldn't reasonably be expected to have known about the loss of tax beforehand.

The time limit on a discovery assessment is longer and the investigating officers can look into historical tax records.

For basic innocent clerical errors, they can look back four years. If they suspect that careless mistakes have been made then this time limit is extended to six years (except for VAT where the limit remains at four years). For suspected fraud, negligence, or dishonesty the limit is extended to 20 years in all cases.

How To Avoid A Tax Investigation

You can't always avoid an investigation because in some cases they truly are random. If you feel that you are having too frequent tax audits or that the investigation is being triggered under false information, you can appeal it at the very start.

Otherwise, your best chances of avoiding an investigation are to be very precise and correct with your tax returns and records. Don't pay tax late, ensure that your accounts are up to date and that they match the amount of tax that you pay.

If you have a complicated tax situation, such as offshore bank accounts, a good accountant will be able to keep these records transparent and easy to understand for HMRC.
