Social services were asked to make an assessment of the family in January 2015 after an incident between the parents, the tribunal heard.
Ms Taylor, who had been a social worker for 10 years, was assigned the case.
She recorded visiting the parents and the children at their schools, setting out statements allegedly made by the children and reporting on their demeanour.
In March 2015 the case was transferred to another social worker, witness 1, who visited the family.
He said the family had made it clear they had not been visited and he then contacted the children's school who also said they had no records of Ms Taylor seeing the children there.
He then informed his line manager, witness 2, who confronted Ms Taylor.
She said Ms Taylor said she could not remember the visits and described her as appearing flustered, going red and changing the subject.
Ms Taylor was suspended by her agency shortly afterwards.
She did not appear at the hearing on 8 May but had denied the allegations in an email in February 2016.
The panel determined the misconduct, "involving as it did the risk of harm to vulnerable children", meant the only sanction was to strike her name from the profession's register.

Sidibe, who died on Thursday, is known for his black and white studio portraits that captured the lives of young Malians in the 1960s and 1970s.
Critics say his photos of Mali's post-colonial period helped people see the West African nation in a new light.
In 2007, he became the first African winner of the Golden Lion for lifetime achievement at the Venice Biennale.
People on Twitter describe him as a talent whose images of popular and youth culture still resonate among young photographers across Africa.
Sidibe's work captures the lives of young men and women, often showing off a prized possession like a watch or a motorbike.
He also captures street scenes and young men seducing girls at parties with a sense of newfound freedom and identity.
Sidibe has work in several private and public museums around the world.
He became famous around the world after holding his first exhibition in France in 1996
Andres Magnin, Malick Sidibe's close friend and owner of the Parisian gallery which represented him, called the photographer an author "of thousands of images of tenderness and beauty".
"A photographer of the young generation of an independent Mali, untroubled, free, modern, full of joy and hope... He was generous, welcoming, loved by all the young people in Bamako."
A social worker who lied about visiting two children who were potentially at risk of harm has been struck off.
