Accept payments with new company in a few weeks

What benefit do you seek from doing it offshore as opposed to a local US company? Tax burden is going to be the same in the end, and you can probably get a company and bank account set up in a matter of days.

Opening a company is fast (a few days if you have your KYC ready to go), but banking is going to take weeks, possibly months. A faster, interim option might be to use an escrow to hold the funds while you open an account.

Many jurisdictions and banks especially put up extra barriers for Americans. As an American, I'd suggest Cayman Islands first and foremost, and Saint Kitts and Nevis and BVI second. Banks and service providers there are a little bit more comfortable with Americans in general than many others.

Can also try Isle of Man and Channel Islands. Banking tends to be easier to arrange there.

There are a few higher end service providers that would be suitable for this. Speak with to the likes of Appleby, Walkers, Conyers, Maples, and Vistra. You'll want this set up with someone who understands the laws and tax implications, not just an incorporation mill that throws you to the wolves after you got your company.

Thank you. I was asking about offshore because I thought that offshore would be more anonymous for the US and I can delay the tax payments or reduce my tax burden.

No change to your tax bill. Offshore is as secretive as ”” or less secretive than ”” for example Wyoming, Delaware, or New Mexico LLCs.

I am a Turkish citizen living in the US, not an American; but US resident for tax purposes. Would this change anything for not getting as many barriers applied to Americans?

It's better but you're still a US person as defined in FATCA by being US resident. It's not a huge obstacle, but it does limit your options.

I can use my Turkish passport and residence in Turkey.

Don't lie to banks. If/when they find out you deceived them, that's a sure fire way to get your accounts terminated and funds frozen pending a court order to release them.

I also heard about already established companies we can take over at offshore. Would they come with bank accounts? Would you recommend this route?

Shelf companies speed up the incorporation process by bypassing it entirely. Account opening is the same in either case. Once ownership of the company changes, the bank will repeat KYC and treat it as a brand new application.

If I decide to go with US company and bank account due to time issue or not seeing much benefit from offshore if too much risk, is Delaware the best option? I live in Florida but can get a virtual mailbox and registered agent to open an LLC in Delaware.

I'm careful about throwing around words like "best" and "recommend" because they imply someone has studied your situation in detail and come to an informed conclusion. However, Delaware is popular for good reasons, as are Wyoming, Nevada, and New Mexico. In addition to plenty of literature available online that discusses and compares them, have a chat about your options with a local attorney.
