In Poland there are some complexities when you run a company / employ, but as an employee it's relatively straightforward UX where you click through a government-operated "income tax fillings wizard" and either just OK a pre-filled declaration or add a couple missing items. Paper filling is a bit more complicated, but I think you can get help at the tax office to get 1 or 2 forms sorted out.
For self-employment I send 2 documents per month regarding my expenses (which is somewhat easy if you understand the rules), plus one or two summaries per year. Hiring is a bit more complicated, I only file simplified declarations for employing private people as contractors. Otherwise I'm pretty much a worst case scenario as I file 7 different yearly declarations covering most possible sources of income defined in the law. It's not that bad, but it could be better.
Running a company can be practically automated with an online accounting SaaS, including payroll. Laws tend to be relatively understandable and there isn't much complicated math. Most of the recent confusion was around shitty laws poorly implemented and then partially reverted by our previous government. I did not enjoy that, but there were some decent online writeups explaining how to proceed.
