Very strange thread. I don't think that there is legal way to make your taxes smaller in any country. There are texts in the laws in Bulgaria that say that if you are in s specifick social group you might pay less taxes but they are fixed and they are not mistake in some law which you can use to make your taxes smaller.
There is a legal way to decrease your taxes. You need spends, that is one of the ways. Maybe the best one. Of course your accounting company that serves you knows how and I believe that will give you more options about this. Let us know where you operate on as av location and what niche. Good luck. We all dealing with then. This is the only thing in common with every business.
You can reduce taxes at any moment, legaly. You need advanced accounting and everithing will be fine. Only profesional accounting service can point you to those ways of decreasing your taxes legaly.
Do not try to cheat the system, just play its game. That's enough.
