Good drop. You can incorporate in any state apply for a foreign entity permit in the state that you live in. The best states to incorporate in are Delaware and Nevada from what I understand.
Yeah, NH is a good one too. I'm in MA so I went with NH. No income tax and reporting requirements are minimal.
Keep in mind you have to pay taxes on the business you do within your state unless you can justifiable say you did the business in Delaware or whatever. Usually will only work if you have an online sales biz. If say you're making money on selling t-shirts in Cali and you're incorporated in Delaware, you'll still have to pay Cali tax as a foreign entity.
But your not looking to keep TONS of cash in the bank. The goal is keep kust enough cash to show legit Income to be able rent an apartment or get a car note or lease a whip.
The more the better tbh. Banks love to see you have plenty of paper and even more behind it if something went wrong. But yeah, generally speaking you only have to put in enough to justify what you want to buy. I'd put in a little bit more to give yourself a cushion but realistically if its solely YOUR company, it doesn't matter how much money you put into it since you can take it out anytime (thus giving you liquidity). Propping up your biz account is far more valuable than keeping it in your personal accounts.
