Now known as employer-financed retirement benefit schemes (EFRBS), unapproved occupational pension schemes that employers used to set up to provide top-up benefits for employees who were caught by the pensions cap. No new UURBS can be set up since 6 April 2005. The employer entered into a contractual commitment to pay a pension at retirement, but did not make any payments to fund that pension promise. Instead, it simply paid out benefits at retirement. UURBS could not be approved by HM Revenue & Customs (HMRC), but an employer could deduct benefits paid to an employee from its liability for corporation tax.
