Whether or not you need to file a return usually depends on 3 things:
How much money you make (gross income)
Your age
There are 5 filing statuses:
Your filing status is single if, on the last day of the year, you are unmarried or legally separated from your spouse under a divorce or separate maintenance decree, and you don’t qualify to use the head of household or qualifying widow(er) filing status. You are also single if you were widowed before January 1, 2010, and didn’t remarry during 2010.
You’re considered married if, on the last day of the year, you are legally married and not legally separated under a divorce or separate maintenance decree. A married couple can choose to file a joint return or separate returns. If you live in a state that recognizes common-law marriages, then you can also file as a married couple.
If your spouse dies during the year, both you and your spouse are considered married for that tax year. If you don’t remarry during the year, you can file either a joint return or separate returns. If you do remarry in the same year that your spouse died, you need to file either a joint return or separate returns with your new spouse, and file a married filing separately return for your deceased spouse.
A married couple may choose to file a joint return or separate returns. However, a joint return often results in a lower federal tax. If you file separate returns, the tax rates are generally higher and several deductions and credits are reduced, limited, or not allowed at all.
You can file as qualifying widow(er) if all of these requirements apply:
You were entitled to file a joint return for the year that your spouse died. It does not matter whether you actually filed a joint return.
Your spouse died in either of the 2 tax years immediately preceding the current tax year. For 2010, this means that your spouse died in either 2008 or 2009.
You have a child or stepchild whom you claim as an exemption on your return. This does not include a foster child.
You paid more than half the cost of maintaining your home, which was the home of your child or stepchild for the entire year.
You can file as head of household if all of these requirements apply:
You were unmarried or considered unmarried on last day of the tax year.
You paid more than half the cost of maintaining your home for the year.
A qualifying person lived with you in the home for more than half the year (except for temporary absences). However, if the qualifying person is your dependent parent, he or she does not have to live with you. See Publication 17, Your Federal Income Tax, for more information about who is a qualifying person.
To be considered unmarried for tax purposes, you must be legally separated under a divorce or separate maintenance decree, or all of these requirements must apply:
You file a separate return from your spouse.
You provided more than half the cost of maintaining your home for the entire year.
Your home was the main home of your son, daughter, stepson, or stepdaughter, or foster child for more than half the year.
You can claim an exemption for the child. However, you meet this test if you cannot claim the exemption only because the noncustodial parent can claim the child, See Publication 17, Your Federal Income Tax, for more information.
Your spouse did not live in the home during the last 6 months of the year.
Example: Let’s assume that you’ve lived apart from your spouse since February 3, 2010, you don’t have a divorce decree or a written separation agreement, and you don’t want to file a joint return. Because you paid more than half the cost of maintaining the home where you and your son lived all year, you’re considered unmarried for tax purposes, and you’re entitled to file as head of household.
By filing as head of household, you might be able to take advantage of some credits and deductions that aren’t available to married filing separately filers, such as the Earned Income Credit, child and dependent care credit, education credits, and the student loan interest deduction.
For more information, see IRS Publication 501: Exemptions, Standard Deduction and Filing Information.

If your parent (or someone else) can claim you as a dependent, the IRS looks at your gross income in terms of earned income and unearned income to determine whether or not you need to file a return. Check the list below to see if you need to file.
You must file a return if any of the following conditions apply:
Your unearned income was more than $950
Your earned income was more than $5,700.
Your gross income was more than the larger of $950 or your earned income (up to $5,400) plus $300.
You must file a return if any of the following conditions apply:
Your unearned income was more than $2,350.
Your earned income was more than $7,100.
Your gross income was more than the larger of $2,350 or your earned income (up to $5,400) plus $300 plus $1,400.
You must file a return if any of the following conditions apply:
Your unearned income was more than $3,750.
Your earned income was more than $8,500.
Your gross income was more than the larger of $3,750 or your earned income (up to $5,400) plus $300 plus $2,800.
There may be times when you need to file a return even though your income falls below the gross income filing requirements. The most common reasons are:
You owe uncollected Social Security or Medicare tax, usually on tips that you didn’t report to your employer.
You receive advance Earned Income Credit payments from your employer during the year. These payments are reported on your Form W-2 in box 9.
You’re self employed and have net earnings of $400 or more.
Even if you don’t have to file, you should file a federal tax return to get money back if:
You had federal income tax withheld from your pay.
You qualify for the Earned Income Credit, additional child tax credit, or the health coverage tax credit.
Since you’re due a refund, you don’t have to worry about paying a penalty for filing a late return. So, don’t delay -- make sure to file a return to get your money back. If you don’t file a return to claim your refund within three years, the money becomes the property of the U.S. Treasury.
