Closing disputes with HMRC

Tax legislation gives the taxpayer a number of ways to challenge a HMRC enquiry including the right to challenge unreasonable demands for documents and information as well as challenge the inspector’s conclusions. However, challenging a decision can be time consuming and costly.

Are you under investigation?

Being investigated by HM Revenue & Customs (HMRC) can be a stressful, lengthy, intrusive and ultimately a costly experience. Here at Mazars we will support you, help remove the stress, take control of the investigative process, minimise intrusion into your private life and get the best possible outcome for you.

HMRC Criminal Investigations and unannounced visits under the Police & Criminal Evidence Act 1984 (PACE)

The nightmare scenario – 7am in the morning, fast asleep, and suddenly there is a loud knock on the door and officials from HM Revenue & Customs announce themselves, accompanied by Police officers, armed with a warrant to search your house and business premises, and you are placed under arrest and taken to a police station for questioning in connection with suspected tax fraud. This can and does happen. So what do you do?

Are you at Risk of a National Minimum Wage Investigation?

In 1998 legislation was enacted that first introduced the concept of the National Minimum Wage (NMW). From 1 April 1999 the legislation required all employers to pay their workers a guaranteed minimum wage which at that time was £3.00 for 18 to 21 year olds and £3.60 for over 22 year olds. The amounts have increased annually and over the years the NMW has been broadened to include apprentices, 16-17 year olds and from 1 April 2016, the National Living wage which applies to over 25 year olds.
