On 3 April, Ms Simkins accepted a bankruptcy restrictions undertaking (BRU), which allows a bankrupt person suspected of misconduct to accept restrictions without needing to go to court.
She will be barred from managing a limited company for a period of seven years, as well as from taking out a loan of more than £500 without disclosing the restriction.
She will also not be allowed to work in some senior roles in the NHS.
Senior official receiver at the IS, David Chapman, said: “Sonia Simkins deducted pension contributions from her staff’s wages but failed to pay more than £75,000 into the NHS pension fund, while the closure of Hawes Lane Surgery had an immediate impact on staff and patients in Rowley Regis.
“Following an Insolvency Service investigation by the Official Receiver, Simkins accepted her misconduct.”
In a statement, the Black Country ICB said: “The ICB were made aware of the closure [of the surgery] on Wednesday 24 July.
“Clinical services were temporarily moved to Portway Family Practice to ensure patients had ongoing access to local GP services, and arrangements were made to relocate all patients to a different GP practice in their local area.
“Hawes Lane Surgery is now closed and the contract for the practice has ended.”
