An obscure title I know, but this is an important one. If there are any conditional terms in your stock purchase agreement (and there probably should be – in the form of a buy-back right for the company) then you’ll want to get an 83(b) form to the IRS to document that you purchased your stock at fair market value. That means you’ll pay less in taxes in the future if you sell the stock.
The 83(b) must be submitted within 30 days of when you receive your stock. Talk to your lawyer to get educated on this. It has major tax implications.
The 83(b) is important. You do not want to mess this up! Talk to your attorney or accountant about this!
