check? EFT? ACH? bank transfer? depends on the amount. When you are dealing with that much money, Step 1: Accountant, Step 2: Attorney. You will be paying taxes, it is their job to minimize it. It is not your job to worry about it. If you are worrying about it, You. Are. Doing. It. Wrong.

They just make a bank transfer. The real issue is the taxation.

Every country has a threshold for how much someone can receive without paying taxes.

If my nigerian princes have taught me anything is that these kind of things are always best done by western union.

Using legit regular banks would be your best bet to avoid scams or being accused of fiscal crimes.

It depends on where the billionaire’s and your bank account are located (some restrictions may apply), but a normal bank transfer works perfectly for any amount. Of course for large amounts it’s better to contact the banks first because it may reject a large deposit if it comes out of the blue.

For donations there will be taxes and some bureaucracy, the anti money laundering will be triggered, but it’s nothing impossible to handle.

OP, if this is anything more than “hypothetically”, you are absolutely definitely being scammed right now. Break off chat with the “billionaire”. If you’ve given them your financial details, call the phone number printed on the back of your bank card. If you use Windows or MacOS, run a scan with Seraph Secure to make sure nobody has remote access to your computer.

That said: billionaires deal with banks and financial institutions of all kinds all the time. They’ll have their bank communicate directly with your bank before making a bank transfer, so both banks know exactly what’s happening. You may need to pay tax on the donation/investment. Use some of the money to hire an accountant.

They don’t, they want to help themselves, if you happen to benefit as well, it’s basically a rounding error on their part which they’ll be sure to minimize in the future.

It’s a scam at best. At worst you find yourself being part of a death game, thinking you can win all the money by killing all of the other players - only to get executed in the end anyway.

They will only do this in context of a company. Get a lawyer to setup a llc. They do sometimes give money this way - see angel investors, but you need a company for legal reasons.

Tell them you want a meeting in person to discuss exactly what the investment plan is and what they envision coming from it. If they really wanted to invest “millions” then they won’t mind meeting in person

Unless he’s standing at your door with a big bag of clean dollar bills, ignore it.

They don’t.

If billionaires actually wanted to help people, they wouldn’t be billionaires.

Start a foundation, advertise that they are passionate about cause, reach out to you to arrange an in person meeting with you or your legal representative, write a check.

But also, it’s not a donation. You are not a 501c or a 527. There is a maximum gift allowance that is tax free in the US. You have to pay taxes on top of that amount.

You should go through your bank because your bank knows the relevant tax laws and theoretically is capable and willing of countering money laundering

You don’t get to be a billionaire by being nice. They will wring every last bit of value out of you.

What if I spontaneously sprouted wings and flew? It’s about as likely.
