Remote work for an American, what to apply for?

Question

Distant work

Hello!
I work remotely for a company in the USA. We signed a contract with obligations, fees, etc. In it, I act as a contractor, which is logical. I receive salary every week through paypal. I live in the Russian Federation, I want to be officially employed. I read similar topics here on the toaster and in other blogs about remote work. I did not find more or less intelligible answers to my questions.
1. What is required from the company? Any additional contracts/documents?
2. What is the type of taxation? Because in some threads on the toaster, people write that you need to choose 13% - supposedly safer.
3.

When a currency is sent to you, it falls into the transit account. You cannot take it off. It is necessary to provide a package of documents that confirm the legality of the translation. The composition of the documents depends on the bank. In my case, these are 7 documents that I have to provide every month.

What are the 7 documents?
Thank you.

Answer 1

13% easier, but not particularly secure. If you open an individual entrepreneur, you can legally reduce the tax to 6%.
According to the composition of the package of documents, no one will tell you exactly, call the bank where you want to open a current account, consult with currency control.
Often you will need an invoice and a translation of the contract, the need for other documents depends on the bank.

Answer 2

I have an IP on the simplified tax system from income (in our region the rate is 4%).
To receive payments, I opened an account with Tochka Bank. There were no problems at all in opening an account, there was no need to go anywhere, everything was done remotely and through a courier service. Opening an account (and all related operations - free of charge). Currency control is inexpensive. Tariffs are also reasonable.
An agreement with the company was required to open an account. I provided it in English, the bank itself did the translation, and for free, it just took a few extra days. If the contract is with a translation, then it’s generally good. Well, you will still need all sorts of certificates of individual entrepreneurs, PSRN, a declaration for the last year, etc. All this usually lies in a special folder for any individual entrepreneur :)
I worked for an Australian company, received payments in foreign currency. Currency control took at most a couple of hours and everything was done by the bank. If the total amount of receipts is exceeded, the bank itself is engaged in a "currency transaction".
Settlements with the company were based on invoices, which I also sent to the bank.
In the declaration, he indicated receipts in rubles after the sale of the currency.
Didn't sweat at all!
