Savvaidou studied law at the National and Kapodistrian University of Athens in 1995 before completing several postgraduate qualifications at the Panthéon-Assas University in Paris. Those included a diploma in French studies (DEUF), a Master's degree in public law (DEA de Droit Public Intern), a master's degree in public finance and tax law (DEA de Finances Publiques et Fiscalite) and a PhD with the thesis title: "The compulsory collection of taxes in French and Greek law". Her PhD was completed in 2003. From 2008 to 2009 she completed a postgraduate program on "Comparative Tax Policy and Administration" at Harvard University.
Savvaidou pursued post-doctoral research into corporate taxation at the University of Athens. She has also taught at the University of Athens, the National School of Public Administration and the National School of Judges. She is currently a lecturer at the Aristotle University of Thessaloniki as well as a visiting professor at University of Macedonia. She has been awarded by European Commission Jean Monnet Chair in European Tax Policy and Administration.
She has published numerous books and articles in tax policy and administration. These include the monograph entitled "Financial Transparency.

Savvaidou has worked as an adviser to the Ministry of Finance and to the private sector over the issue of tax. Before becoming the Secretary General, she worked as a senior manager at PricewaterhouseCoopers.
Savvaidou became the Secretary General of Public Revenue on 24 June 2014, succeeding Haris Theoharis, who cited personal reasons for his resignation. The role effectively made Savvaidou the top tax official in Greece as she was made head of the public revenue authority, responsible for tax collection.
On 16 October 2015, the Minister of Finance, Euclid Tsakalotos, at the request of the Prime Minister of Greece, Alexis Tsipras, asked Savvaidou to resign. This took place because an anti-corruption prosecutor, Yiannis Dragatsis, had filed charges against her and she was expected to answer questions over them on 20 October.
