So in the US you can't just take cash out of your company?
Not like you do!
If your company has a legal form other than sole proprietor (LLC, corporation, partnership), you have five options that I know of (but I'm not an accountant, there may be a few others):
(1) Collecting wage or salary income from the company. (Must pay Social Security tax, etc.)
(2) Withdraw cash from your company as "dividends" or other forms of "profits", and pay taxes on that as income. Putting the money back in doesn't get you any deductions!
(3) Withdraw cash from your company "return of paid-in capital", but only up to the amount you originally put in, and there are further accounting restrictions on that.
(4) Borrow money from your company. (Which is essentially what you're doing.) This is SEVERELY discouraged. You are expected to draw up an actual lending contract, with lawyers, interest, terms, etc., the way you'd write an arms-length lending contract with a bank or investor. If you don't do this, the IRS (tax service) will decide it wasn't a loan, declare that it was a withdrawal of profits, and tax you on it like #2. (Or sometimes #1 or #3.) It is also sometimes declared to be defrauding the company!
(5) A bona fide purchase or sale between the company and yourself; it must be similar to an arms-length transaction, and if it isn't, the IRS will recharacterize it as #1, #2, or #3.
If you're self-employed as a sole proprietor, your company "is you".You have company expenses and company revenues (which must all be documented), and the difference is taxable profit. You can comingle your business and personal accounts, but the accountants' advice is STILL to set up separate bank accounts for the company. And if you comingle them it both doesn't benefit you and usually hurts your ability to prove that something was a business expense (thus making it nondeductible).
If you have an LLC or a corporation or a partnership, you MUST NOT comingle personal and business property, and can actually get put in prison for it. People do it all the time, but you're *really* not supposed to. Each transfer between the partnership account and the personal account should be marked at the time with its specific identity, whether it's salary, profit-taking, return of originally invested capital, investment of additional capital, a loan, a purchase, or whatever. The IRS frowns on loans and asset purchases, so their terms must be similar to those of an "arms-length" deal and have to be really well-documented.
There are indeed many partnership type businesses, but I don't know whether that's a direct consequence of anything in particular. I have a very simple company structure, with my wife as a silent partner holding one share, I hold 99.
Right. So in the US, you'd have to have separate company (partnership) bank accounts and personal bank accounts. Transfers between the accounts would have to be marked with their nature immediately -- you couldn't just withdraw a bunch of money and later decide that it was a loan and pay it back. It would be presumed to be profit-taking. Transferring the stock into the partnership and then transferring it back after the end of the year would also likely be considered a "sham transaction" and disallowed. In the US you *can* loan as much money to your company as you like, even at zero interest -- but the other way around, the company loaning money to YOU, is not kosher.
I guess in Belgium they have a tax on the amount the company loaned to you, which is what you're messing around with. In the US such a loan is typically simply prohibited (unless you can prove that it's a proper arms-length commercial loan) and recharacterized as profit-taking.
In the US, claiming that you were "borrowing" from your controlled company without proper documentation is one of the best ways to get in big, big trouble with the IRS. Which is why this surprised me.
