Meet your right-hand man in Slovakia
“I’m Milan Černák. Since 2005, I’ve been helping businesses, primarily from the DACH region, navigate Slovakia’s tax landscape. In 2010, I founded LEON Advisory Group, which I successfully exited to the international RSM network in 2023.
I left the big advisory world because I need to see the real impact of my work. I don’t want to hand over a memo and disappear. I want to know your people, your processes, and your day-to-day reality and improve your results in a way you can see in the data and feel in the calm at HQ.”
Results you can actually count
Consolidating data from multiple accounting systems
Problem:
A German parent company managed multiple Slovak subsidiaries, each using different accounting software. Financial reports were delivered only once a year.
Solution:
I implemented an online system that processes and aggregates all data into a single, structured dashboard. This included the elimination of intercompany transactions and real-time budget tracking.
Result:
24/7 online overview across all subsidiaries, in one place.
Dividends without double taxation
Problem:
An Austrian company was bleeding capital by paying dividend taxes in both Slovakia and Austria.
Solution:
I redesigned the corporate structure and implemented a GmbH & Co. KG model in full compliance with Slovak law.
Result:
Total tax burden on the transaction dropped by 50%, after applying double taxation treaty rules.
I’ll set up clear processes so your Slovak subsidiary stays in control and in good shape
Reporting your HQ can finally understand
Is your German headquarters receiving numbers they don’t understand? I translate your Slovak accounting into your parent company’s language, including HB II and IFRS. No surprises or unexpected losses at the end of the quarter.
Tax optimisation at every step
Paying more tax than you have to? Most advisors react too late. I get involved before the liability arises, not after. You won’t pay a single euro more than necessary.
Financial cover for your local management
Is your Slovak production manager delivering results? Let them focus on what they’re good at. I take over all financial communication with the German executives. Your local team gets the headspace to focus on the business.
Your Slovak taxes and business strategy in the right hands
Tax supervision of your Slovak entity
I review your accounting and tax returns. I eliminate risks and catch errors before the tax authorities do. Your parent company sleeps easy.
Non-executive support for your business goals
I sit at the table with you and help make the decisions that matter. I advise on market expansion and process optimization with the mindset of a partner who guards your cash flow like his own.

Straight to the point. Here’s how we work together
We set up the partnership without unnecessary bureaucracy. Direct, practical, with a clear plan from day one.
1
Discovery call – we talk through what you need and how I can help you get clarity and control.
2
Initial audit – I take a critical look at your processes, risks, and results in a broader context.
3
In-person meeting – I visit both your HQ and your local branch to understand the everyday reality of your business.
4
Strategic proposal – I draft a strategic plan built around your KPIs. What to change, what to keep, when and why.
5
Ongoing meetings & reporting – we establish the system and agree on what information gets sent, when, and how.
Questions I get asked most often
How are you different from a standard consulting agency?
I spend real time inside your company and get involved in your internal processes. I’m not an external consultant who writes a memo and walks away. I’m a non-executive director who is personally invested in your success.
Do you only work with large companies?
My typical client is a DACH-region business with both a production operation and a production manager in Slovakia but no one managing the finances locally. I come in as a financial non-executive director: the link between local management and the German parent. The size of your turnover isn’t the condition. Your willingness to do things properly is.
When will I see the first results?
Right after the initial audit. My goal isn’t to write hundred-page theoretical analyses that gather dust on a shelf. Within the first month, I’ll identify the critical issues and implement processes that immediately give you more control and more peace of mind.
Is your Slovak subsidiary as solid as you think?
Don’t risk costly mistakes from not knowing local legislation. In a 30-minute call, I’ll show you the risks you’re currently exposed to and how to prevent them.
No presentation slides. No commitment. Just you and your situation.
