You also have corporate interests that profit from convoluted tax filing and lobby the government to keep it confusing so individuals continue to use their products.
But, it seem like a particular US infliction to make paying taxes as hard as possible? Plus, they sanction you in extreme ways if you don't manage to jump through all the hoops?
I pay taxes in many jurisdictions. Here is my experience: Netherlands (my home country): the tax authorities send me a proposal about payable taxes. This includes income from my business, my partner's job, our common investments, and some investments/business interests that are exclusive to me. I correct whatever is required (with the deadline being April 1st), and I'll get my final settlement sometime in June/July.
Germany/France: I provide the tax authorities with my Dutch tax identification number, and they confirm they're fine with that in 3-4 months time. Rwanda, Nigeria and Zimbabwe: I also provide my native tax details (sometimes using my mobile number, sometimes using my NL 'SSN'), and they're fine with that, sometimes after billing me a small percentage over some income.
US: I honestly have non idea where I stand. The IRS refuses to talk to me, yet summons me to physical meetings in the past that I cannot legally attend. I have hired several attorneys, none of which seem to be able to help.
I probably owe several HUNDREDS of dollars in US tax. I've not visited the US since 2004, and have not done any business there since 2002.
Yet... I'm apparently a much-wanted tax fugitive in the US. Does that count on a FAANG-inbound resume?
