I filed my first taxes when I was 16. YES! If you earn income then you must file taxes. You employer is most likely withholding (unless you're not 'on the books) based on the form W4 you filled out.

If you worked all this time and did not have money withheld, you're in for a big surprise - as you could owe a lot at once. Being 16 and having these smaller jobs, you probably don't make enough to have to pay, but you still must file.

Your !6 y/o doesn't have to file taxes yet. He is too young for this responsibility and he's not at the right age to pay because he is still going to school and not yet earning his own money. People who file taxes are adults and working.

It depends on how much money your 16 yr old makes. As a general rule of thumb, children do not have to do so until they are 18, I believe. Once a child makes a certain amount of money (I do not recall how much) you need to claim it on your taxes, or they need to file themselves. This is a question that you should be able to get answered by a local tax preparer with no obligation to them. Otherwise, you can look it up on the federal govt's website, or your state one. Here is the page on child filing from the federal govt'. If you read it from the top, it should be easy enough to file. http://www.irs.gov/publications/p929/ar02.html#en_US_2010_publink1000203770 As I do not know which state you are from, I cannot help you with that info. Generally, you would type in the "ask" field your state government taxes to find the state site, then look up child earnings or child wages in the search field.

I filed taxes from the age of 14.
