How much money can a teenager earn before he has to pay taxes?

In the United States, for the tax year 2023, a teenager can earn up to $14,050 in earned income before needing to file a federal tax return. However, if they have unearned income, such as interest or dividends, the threshold is lower at $1,250. If their total income exceeds these thresholds, they may be required to pay taxes. It's always a good idea to check the latest IRS guidelines or consult a tax professional for specific circumstances.
