Hi!
I am Mateusz Nowak, a legal adviser and tax adviser with a passion. I started my educational path at the Faculty of Law of the Jagiellonian University. Instead of following the typical path of a lawyer, life led me in the direction of taxes.
While many of my colleagues in the industry view taxes with trepidation, I see them as an endless world of possibilities. although I am a lawyer by training, my passion comes down to one thing: helping clients navigate the complex world of taxes. That’s why I also completed a master’s degree in financial auditing at the Cracow University of Economics.
For more than three years, I had the pleasure of heading the Polish legal and finance department at the startup Revolut, one of the most innovative fintechs. This experience taught me how to combine the corporate world with the agility of start-ups.
Now I run my own accounting office in Krakow, Solpoint www.solpoint.pl where I combine my extensive experience with my interest in taxes.
I invite you to read my blog, where I share my knowledge and experience in a relaxed form. Together we will discover that taxes can be…. well, maybe not fun, but certainly less complicated!

Should you have any questions, I’m more than happy to answer them.
