Standards Commissioner Kathryn Hudson found that the payments made to Ms Dorries as a result of her appearance on the show should have been declared.
Ms Dorries updated her entry on the register of MPs' interests at the end of October, covering the previous 12 months.
It showed Averbrook's gross income was £142,000, giving a profit of £82,000, and that Ms Dorries had taken a £10,000 dividend on October 30.
She spent approximately 60 days working on Averbrook's projects, which were described as "writing and media appearances".
In its conclusion the committee said:
Ms Dorries must register the details required by the rules. That leaves her initial failure to abide by the registrar's advice, and her attitude toward the Commissioner's inquiry.
The House's Code of Conduct and disciplinary system depend on Members being prepared to explain their conduct, to submit to public scrutiny and where necessary, to respond to the Commissioner's inquiries.
The committee said Ms Dorries should consult the registrar within 21 days about the detail of her entry on the register.
"We will monitor Ms Dorries's compliance and will recommend further action if necessary," the report said.
