There are several reasons why HMRC may initiate a tax investigation. One common reason is if they suspect that you have underreported your income or claimed false deductions on your tax return.
They may also investigate if they suspect that you are involved in illegal activities, such as money laundering or tax evasion. Additionally, if you are selected for a random audit, this can also lead to a tax investigation.
Whatever the reason, it’s important to take the investigation seriously and cooperate fully with HMRC to ensure a fair and timely resolution.
