Tax Investigation
FAQ

Most tax investigations happen because HMRC has reason to believe that some aspect of your tax return or business accounts is wrong. They may have received a tip off, some figures in the tax return may not tally with other information they have, or the return may have been sent in late.

One important way to minimise the risk of becoming a target for investigation is to make sure your personal tax return and company accounts are always delivered to the appropriate agency (Companies House/HMRC) on time. Another way to avoid suspicion is to use the dns online accounting portal, employ a good accountant, keep hold of receipts and be scrupulous about correct reporting. Another thing, never ignore any correspondence from HMRC.

No. HMRC randomly selects a proportion of tax returns every year. In the first two years of self-assessment, some 15,000 returns were investigated. HMRC will write to you to let you know that your affairs are being investigated although it will not normally give the reason behind its decision to launch an enquiry. Under the self-assessment regime, the Revenue must start any enquiry within 12 months of the last filing date of 31 January but there is no requirement for an investigation to conclude within a fixed period of time.

If it is found that a tax payer has intentionally misled the tax authorities, punishment can be severe: prosecutions, jail sentences and stiff fines designed to recoup the unpaid tax and penalties.

In cases where minor amounts of income have been undeclared or where small mistakes have been made on the return, normally the matter can be cleared up with a few phone calls and submission of relevant pay slips. If the problem appears to be a simple one of omission, HMRC can ask the tax payer to answer specific questions or provide documents that might answer the question. If it is discovered that tax has been underpaid, the taxpayer will have to pay what is due plus any penalty or interest accrued. Where serious fraud (amounts of more than £50,000) is concerned, HMRC can start to request information from banks, accountants and other parties if it is the tax inspector’s “reasonable opinion” that this will help the investigation.

Yes, but taxpayers’ affairs are confidential and information will only be disclosed to people that the individual agrees it may be given to, such as dns or another adviser. But, HMRC can ask former employers, customers, suppliers or colleagues for information relating to its investigation

Yes, of course, but you may have to go back through the whole accounts’ years (legally you must keep six years), and to collate this and submit it all is quite a job if you are still trying to run a company.
