Judges will deliver their verdict in the oldco Rangers "big tax case" court battle next week.

The Supreme Court will hand down its findings on Wednesday morning, after the liquidators of oldco Rangers sought to overturn a previous ruling.

Her Majesty's Revenue and Customs (HMRC) won an appeal in November 2015 over the use of the now-outlawed employee benefit trusts (EBT) at the club during Sir David Murray's stewardship.

The Court of Session agreed with HMRC that the scheme, which involved payments to former employees, players and staff, amounted to "a mere redirection of earnings which did not remove the liability of employees to income tax".

The judges decided any income derived from employees' services was earnings and subject to income tax.

Oldco liquidators BDO asked the court for permission to appeal to the Supreme Court, the highest in the UK, and this was granted.

The key issues to be decided by the Supreme Court are whether the Court of Session "erred in law" in its findings and whether the payments "derived from" work and were subject to PAYE and income tax.

The Supreme Court also said the judgment will settle whether the funds put into each EBT "subtrust" were solely for the disposal of individual employees and, therefore, liable for tax.

The decision relates to Murray Group companies, including the liquidated company now called RFC 2012 plc, and does not affect the current regime at Ibrox.
