Most likely-last I looked if you mean Fed The cutoff is VERY low usually a few hundred within a month or around 3k annual
Anyone with any income, or even without an income can file. You are required to file Federal taxes if you made more than $1,800. Illinois requires anyone that earns or receives income in the state to file state taxes.
$600 is the line for filing taxes. So yes, if you made $2000 you should file.
You can file a return no matter what your income level is if you have some reason to do so. With this amount of income you are not required to file but you can if you want to.
Anyone can file a tax return with any amount of income. You may want to do this if you paid in withholding taxes or you qualify for some credit that will benefit you. You are not required to file with this amount of income but you can if you want to.
You need to claim your income as being self-employed
No, if you made anything less than $600.00 in one year then you do not need to pay taxes on that income. However, you should still file your taxes for that year.
You do not have to file taxes with the IRS if you have received no income for a tax year, or if you made below the minimum requirement for filling. The minimum requirement income for 2007 was around $8000.00.
Federal of course and all states you've lived or made income from
No you don't, it is considered hobby money unless you made $5,000 or more, then you DO have to file.
It doesn't matter if you receive an income tax refund or not. The fact is is you worked and had federal and state taxes taken out you would need to file your taxes every year. However, much depends on your filing status (single, married, etc) and how much you made that year on whether you would file. To be on the safe side if you had federal and state taken out of your checks you should file.
For 2009, generally if you made only $3,400 in wages/salaries, then you wouldn't be required to file no matter what your filing status. However, you still can file even when you're not required to file. If income taxes were withheld, you should file to receive a refund of all those taxes. Also, if you're eligible for certain credits (such as earned income or making work pay, etc.), you should file even if you're not required.
Simply file an amended return - a form 1040 X. Your refund will include interest on the excess.
