What is a HMRC Tax Investigation and What Triggers One?
To ensure self-employed persons are correctly paying tax, the HMRC has the right to investigate, particularly where details are not adding up. If they need to do an investigation, they will contact you or your accountant, if applicable, to provide evidence or further information. Some of the aspects they will take a look at include:
- The percentage of tax you pay
- Your accounts
- Your tax calculation
- Previous completed tax returns
- Your PAYE records and returns for employers
- Your VAT records for those VAT registered
The GOV.UK website can provide further information on the type of details they might check and what the process is.
There are many reasons as to why the HMRC might pursue an investigation into your tax records, particularly where there are unexplained anomalies or incorrect figures submitted. Sometimes, HMRC receives tip offs and occasionally will investigate these.
What Are the Different Types of Tax Investigations?
When HMRC carries out a tax investigation, there are three audit levels, including:
Full Enquiry
A full enquiry will involve HMRC reviewing the entirety of the documents. This is most usually done where they believe there is a significant number of errors with the details that have been submitted to them.
Aspect Enquiry
An aspect enquiry only looks into part of your return where they believe there is inconsistencies.
Random Check
Random checks can happen at any point and on any person, whether your details have alerted their system or not.
Tips to Avoid a HMRC Tax Investigation
Hire an Accountant
One way to avoid any type of HMRC tax investigation is to hire a qualified accountant who has dealt with many different types of tax returns. They will make sure you have provided them with all your financial details, such as income, expenses, and capital investments, as well as ensuring all that information is processed correctly.
Most often, tax investigations occur when details are submitted wrong, either wrong figures and/or figures in incorrect sections. HMRC also consider the use of an account as trustful due to the rules they have to follow.
Not only are accounts beneficial when it comes to avoiding a tax investigation, but they too are incredibly helpful for those who own small businesses and have a lot of details to put through.
Double Check Your Tax Return Before Submitting
Regardless of whether you did your tax return yourself or used an accountant to do this, it is really important to ensure that, before your accountant submits the document, you have completely double checked it to see that all the necessary and important details have been included.
Explain Any Anomalies
It is possible that anomalies occur do occur in tax returns, either by accident or on purpose, either for an explainable reason or not. Where you believe you have anomalies that can be described, it is extremely important to do this and, if possible, provide any evidence that justifies this.
Don’t Operate Cash Only
It isn’t uncommon for businesses to be ‘cash only’, but to HMRC this can be seen as a red flag and have the potential to cause a HMRC tax investigation. There are some businesses which are more likely to receive cash over card payments, such as small construction, etc. These are likely looked at more regularly to ensure everything is accurate and no illegal activity is happening.

Make The Effort to Avoid a HMRC Investigation
What we can conclude is that, if you have been untruthful on your tax return and are flagged for an investigation, it could have a lot of implications. You could receive a large penalty or, depending on the severity you might be criminally prosecuted, including prison time.
There might be times where, if HMRC found an error on your return, it was not done intentionally. Where this applies, they will inform you of the error, explain how the return needs to be amended so it’s done currently, and you will then have 30 days to implement those changes.
