I'm also in Romania, making about $95k/year. I'm running it through my company, an LLC (SRL in Romanian). Starting in 2016, you can classify yourself as a micro-enterprise if you make less than EUR 100k ($112k) and you pay 3% in tax if you have no employees or 1% if you employ at least 2 people (could be you and your spouse for instance - that's what I do), then an additional 5% in dividend tax if you want to get cash in your pocket and don't expense anything. An accountant will cost you about 100 EUR (probably less in your case if you have just one monthly invoice to your client).

I'm not sure why you'd want to stay below $55k, depending on where you live you may just get additional projects and outsource them yourself to a junior dev you can monitor. That would give you your two employees to qualify for the 1% tax and you could move more of your workload to the additional dev as he/she learns stuff.
