Our Story
From two professionals with corporate experience to a team of 30 experts — with one goal: outstanding client service.
2017
The Beginning — A Vision for Better Accounting
Przemek and Sebastian founded MTA Group. Both with experience in finance and accounting at multinational corporations, they understood what professional service looks like and wanted to bring that standard to business clients. From day one, Patrycja joined the team, building the firm’s operational foundation.
2020
Patrycja Becomes a Partner
After three years of working together, Patrycja joined as a shareholder. The team continued to grow, and MTA Group obtained the status of Autorisert Regnskapsførerselskap — an authorisation from Finanstilsynet confirming the highest accounting standards.
2024
Karol and Dawid Join as Partners
The firm entered a new phase of growth. Karol and Dawid strengthened the management team as partners. A new office at Fjordveien 3 in Høvik, proprietary IT tools, and industry-specific expertise — construction, hospitality, and beauty. The team had grown to 25 experts.
2026
Today — 600+ Businesses, 30 Experts, One Goal
One of the largest accounting firms in our segment. Our goal from day one has never changed: to be the firm with the best client service. Not the biggest — the best. And we continue to grow, because our clients recommend us.
What Sets Us Apart
We are not just another accounting firm. These are the principles that define every client relationship we build.
Authorisation and Security
Autorisert Regnskapsførerselskap, licensed by Finanstilsynet. Member of Regnskap Norge. Professional indemnity insurance covers every transaction. Your finances are in the hands of certified professionals.
01
Your Language, Your Dedicated Advisor
We communicate in your language, and before the authorities we represent you with full local proficiency. Every client has a dedicated advisor who knows their business and industry.
02
Industry Specialisation
We do not try to do a little of everything. We know industry-specific regulations inside and out — solidaransvar in construction, kassasystem in hospitality, and compliance requirements for beauty salons. This translates into real savings for your business.
03
Transparent Terms
Clear pricing from the outset, with no hidden fees. Regular reports you can actually understand. We inform you of regulatory changes before they affect your business.
04

Behind every number is a person. Meet the experts who manage your company’s finances every day.
