Fedelta OÜ
An accounting firm in Tallinn built on loyalty
The name comes from the Latin word fedelta — loyalty, fidelity. That is the value the whole way of working is built on. We are not just an accounting firm; we are the financial partner that grows alongside the company.
Fedelta Accounting has more than ten years of experience supporting businesses in Estonia. We started as a small team and now keep a representative office in the heart of Tallinn, at Tartu mnt 43 — a step that says what kind of service level we hold ourselves to.
"For us, every client is a personal partnership." — Ksenia Martynova, founder of Fedelta Accounting.
We build long-term relationships in which the entrepreneur has an expert beside them, one who keeps an eye on the business and helps with the decisions that shape its growth.

Our main strength
Expertise built inside the Estonian tax system
Fedelta OÜ was founded and is led by an accountant and tax auditor with years of experience at the Estonian Tax and Customs Board. The team consists of professional accountants who have worked in various financial institutions in Estonia.
That background is why we understand what working with non-residents and international clients actually involves, how different industries and company types differ in practice, and how to keep a company compliant and transparent at every stage.
We offer the full range of services in one place, so that you can concentrate on the business itself instead of on the paperwork around it.
