None directly – you will get unrealized income (or loss) as the value of that 5% goes up (or down). Note that the “value” means whatever someone is willing to pay you for it, which is much easier to measure for a “publicly traded” company. If this is a startup or other private company, the opportunities to sell that ownership will be more limited.
Companies can choose to distribute some of it’s cash (hopefully from excess profits, but not always) to owners in proportion to their ownership. However, this is not really “income” since if the company pays out cash, the value of that company goes down accordingly. If you have $100 worth of stock and get a $5 dividend, you now have $95 worth of stock and $5 cash. But it is a way to get cash from the ownership without having to sell shares.
Companies are not required to distribute profits – it can choose to “retain” them (hence the balance sheet item “Retained Earnings”), distribute them, or use them to buy more assets.
