Well, it is true that everyone has to pay taxes, there are exceptions, especially for people age 65 and older. But there is no age at which you stop filing. You just need to check your income and the tax rules every year to determine if you need to report any of your income.
If you are older than 65, you must file if your taxable income is over $11,200. To file as a head of household, you must have at least one dependent and not be married. If you use this filing status, you must file a tax return if you are less then 65 years old and have at least $12,500 in taxable income. If you are older than 65, the threshold increases to $13,950. Married couples can chose to file a joint return or two separate returns.
