FAQs

Cis faqs 1 1 1
What is an HMRC tax investigation?

An HMRC tax investigation, also known as a compliance check or tax enquiry, is a review of your tax affairs to establish whether the correct amount of tax has been reported and paid.

What can HMRC investigate?

HMRC can check accounts, tax calculations, Company Tax Returns, VAT, PAYE, CIS and other tax records, depending on the scope of the enquiry.

Can you deal with HMRC on our behalf?

Yes. With appropriate authorisation, an accountant can communicate with HMRC and assist with the compliance check.

What should I do if HMRC sends me an enquiry letter?

Do not ignore it. The first step is to understand exactly what HMRC is asking for and the relevant deadlines. We can review the correspondence and help you determine the appropriate response.

Can you help with a CIS investigation?

Yes. We can review CIS returns, subcontractor verification, deductions, payments and supporting records where these form part of an HMRC investigation.

Can you represent us during an HMRC compliance check?

Yes. Subject to the appropriate authorisation, we can assist with correspondence, information requests and discussions with HMRC.

Can you challenge an HMRC penalty?

We can review the basis for a tax penalty and advise on available options, including a review or appeal where appropriate. HMRC generally allows 30 days to appeal a penalty, although the applicable process depends on the type of tax decision.

What is Alternative Dispute Resolution?

Alternative Dispute Resolution (ADR) is a process that can help resolve certain disagreements with HMRC without proceeding directly to a tribunal. HMRC confirms that ADR can be available during or after a compliance check in appropriate cases.

Can you help with VAT, PAYE and Corporation Tax investigations?

Yes. Our HMRC investigation support can cover relevant VAT, PAYE, Corporation Tax and CIS matters for construction businesses.

Does an HMRC investigation always mean I have done something wrong?

No. HMRC compliance checks can have different reasons and may conclude that nothing is wrong. If HMRC identifies an underpayment, it may require additional tax and interest and may also charge a penalty.
