I owe taxes on my monthly retirement income, why is this?

[xmasbaby0 · Accepted solution]

Retirement income is taxable.  Are you receiving Social Security or income from a pension or IRA? 

Up to 85% of your Social Security benefits can be taxable.  There is no age limit for having to pay taxes on Social Security benefits if you have other sources of income along with the SS benefits.  When you have other income such as earnings from continuing to work, investment income, pensions, etc. up to 85% of your SS can be taxable.
