ChatGPT recommended young adults use a simplified 50/30/20 rule for summer job income: 50% for upcoming needs like textbooks and tuition, 30% for guilt-free spending, and 20% for savings. It advised upgrading to high-yield savings accounts, which currently pay closer to 4% or 5% APY, versus standard checking accounts as low as 0.01% interest. For taxes, ChatGPT suggested filling out the W-4 accurately at the start of a first W-2 job, noting take-home pay will be lower due to Social Security, Medicare, and federal and state tax withholdings. For side hustles, if net earnings from self-employment hit $400 or more, self-employment tax is owed; ChatGPT recommended setting aside about 20% of gig income. It also proposed starting a Roth IRA, as a summer job creates earned income, making a young adult eligible to contribute. Financial expert Erick Parker, senior business consultant at Global Business Consultants, agreed on the W-4 issue, stating filling it out accurately prevents a surprise tax bill or larger-than-necessary withholding. He warned that with a side hustle, one is technically self-employed and must set money aside to pay taxes.
