According to efile.com, the amount of money a person can make without filing taxes depends on filing status and age. For tax year 2013, a single person under 65 years old had to make in excess of $10,000 before filing taxes, while someone over 65 years old needed income over $11,500 to file taxes. Dependents have a lower tax filing threshold of $6,100 if they're under 65 years old, single and not blind.
Income thresholds for taxpayers 65 and older. If you are at least 65 years old and receive Social Security income during the year, you are subject to the same filing requirements as any other taxpayer. However, you can generally receive more income during the year than other taxpayers before having to file a tax return.or example, if you are a single taxpayer who earns $2,500 during the year, with $300 withheld for federal tax, then you are entitled to a refund for the entire $300 since you earned less than the standard deduction plus one exemption.
