Assuming that is all the income you are going to report, then you do not have to file. With $600 of income (regardless of whether you can be claimed on your parent's return or not), you will not ow taxes (and thus be required to file).

> or can my parents just claim me as a dependent?

They can claim you as a depended regardless of whether you file. Whether you qualify as their dependent is their problem, not yours.

If you are claimed as a dependent on their return, and you file your own return, just make sure you state you are claimed as a dependent on someone else's return. It affects your deductions and such, but you are well below the limits for taxable income.

Whether you have a State income tax issue is another question.

> Also if my parents do claim me, will that effect my financial aid for college in any way?

Depends upon whether you qualify to be independent for Financial Aid purposes.

If you were born before 1/1/1989, then you are considered independent. Otherwise, see if you qualify for any of the others.

> My parents don't support me at all, they just want the money for claiming me as a dependent.

Then they will be committing tax fraud. But, that is their problem, not yours.

> Please let me know what my best options are here.

Let your parents do what they want to do. If/when you report your income, mark the appropriate box on your tax form. If you want the $70 bucks, then you have to file.

Assuming the IRS somehow finds out about your non-reported income (and you had a lot of it), then:
1) If you don't file, then they can get you for failure to file.
2) If you do file, then they can get you on tax evasion.

Remember, Al Capone was busted for tax evasion, not for all the stuff he did as head of the mob.
