Since 6 April 2012 HMRC is able to require seriously non-compliant employers to provide security to protect against non-payment.

This does not affect employers who have genuine payment difficulties and does not apply to employers who:

Where HMRC think security is necessary it will calculate the amount of the security based on the evidence of the individual case.

The employer may appeal to the Tax Tribunal against the notice requiring security, or the amount. Alternatively, they can ask to have their case reviewed first by HMRC’s internal review team before any Tribunal hearing.

There will be a criminal sanction for not providing security when one has been required, with a fine of up to £5000.

The most common form of security is a cash deposit held by HMRC or paid into a joint HMRC/taxpayer interest-bearing bank account. Security can also be a performance bond which is similar to a third-party guarantee. It may be provided by any bank, building society or other financial institution approved by HMRC.

In Boship Lyons Hotels & others v HMRC [2018] TC6613, three companies, all under the control of one director, were given a requirement to give security for PAYE and National Insurance Contributions (NICs). At the time the decision to issue the notices of requirement to give security was taken:

The director's grounds for appeal were weak. He was going to appoint another director. but had not. He felt he was being personally victimised etc. The FTT dismissed the appeal finding that HMRC’s decision to impose security requirements on the companies was reasonable in all the circumstances.
