how old must you be to work and not have to pay taxes
For example, a person aged 55, filing as head of household, must file a return in 2016 when income is above $13,350. But, someone aged 66 with the same filing status does not need to file unless income is greater than $14,900. Age 65 is a factor for all filing statuses except Married Filing Separately. With that filing status, you must file in 2016 if your income is greater than your personal exemption of $4,050.
