If you live by yourself in 2011, paid more than 50% of your expenses and you earned income you should file tax return claiming your income and yourself.
Such case need to be taken care of by family members. Discuss the issue with your parents first.
First: if you live with your family in 2011 and they pay at least your health insurance and or more than 50% of your expenses and you were below 18, they do have right to claim you.
Second: If you make less than 6 thousand ayear and your age less than 25, you will not get any
credit except your federal withholding.
If your parents paid for school, they can claim you for education credit.
Remember, when your parents claim you as their dependent, you must file a single person but to state that someone else did claim you. Check box 6 of your 1040.
You only claim your wages, but can not claim your credit.
To see the different between your case being claimed by your parents or not:
Make one return claiming your self and all income etc..
Make another return, excluding your exemption but including the entire income,
Now, compare any loss you may encounter if your parents claim you....
show your parents the loss and ask them to help you out..
If you feel your income too high and your family should not claim you, and if your family did not amend their return first, simply write letter to IRS along with the 1040X amendment and
send it to the IRS, which should include: Proof of residency (rental agreement), health services paid by you and showing your address differ from your parents, school address showing different address than your parents.
It will take around 16 weeks to process the amendment . If the IRS approved your amendment, they will ask your parents to revise their return or the IRS simply adjust your parents return based on your information.
