Congratulations on reaching your milestone and enjoying the game! Passive income can be a great way to earn money while focusing on other activities. Some businesses that provide a passive income in GTA V include the nightclub, which generates income from the DJs and technicians, and the bunker, which generates income from weapons sales. Consider investing in stocks or real estate within the game, as these can provide long-term passive income. In real-life, you can use a paystub maker to manage income and taxes better. Good luck!
