You may be able to subtract amounts from your total income (Form 1040, line 22 or Form 1040A, line 15) or total effectively connected income (Form 1040NR, line 23) to get your adjusted gross income (Form 1040, line 37; Form 1040A, line 21; or Form 1040NR, line 36). Some adjustments to income follow.

• Contributions to your individual retirement arrangement (IRA) (Form 1040, line 32; Form 1040A, line 17; or Form 1040NR, line 32), explained later in this publication.
• Certain moving expenses (line 26 of Form 1040 or Form 1040NR) if you changed job locations or started a new job in 2010. See Publication 521, Moving Expenses, or see Form 3903, Moving Expenses, and its Instructions.
• Some health insurance costs (Form 1040, line 29 or Form 1040NR, line 29) if you were self-employed and had a net profit for the year, or if you received wages in 2010 from an S corporation in which you were a more-than-2% shareholder. For more details, see Publication 535, Business Expenses.
• Payments to your self-employed SEP, SIMPLE, or qualified plan (Form 1040, line 28 or Form 1040NR, line 28). For more information, including limits on how much you can deduct, see Publication 560, Retirement Plans for Small Business.
• Penalties paid on early withdrawal of savings (Form 1040, line 30 or Form 1040NR, line 30). Form 1099-INT, Interest Income, or Form 1099-OID, Original Issue Discount, will show the amount of any penalty you were charged.
• Alimony payments (Form 1040, line 31a). For more information, see Publication 504, Divorced or Separated Individuals.

There are other items you can claim as adjustments to income. These adjustments are discussed in your tax return instructions.

This section explains the tax treatment of amounts you pay into traditional IRAs. A traditional IRA is any IRA that is not a Roth or SIMPLE IRA. Roth and SIMPLE IRAs are defined earlier in the IRA discussion under Retirement Plan Distributions. For more detailed information, see Publication 590.

An IRA is a personal savings plan that offers you tax advantages to set aside money for your retirement. Two advantages of a traditional IRA are:

• You may be able to deduct some or all of your contributions to it, depending on the type of IRA you have and your circumstances, and
• Generally, amounts in your IRA, including earnings and gains, are not taxed until distributed. In some cases, amounts are not taxed at all if distributed according to the applicable rules.

The most that can be contributed for 2010 to your traditional IRA is the smaller of the following amounts.

• Your taxable compensation for the year, or
• $5,000 ($6,000 if you were age 50 or older by the end of 2010).

In the case of a married couple filing a joint return for 2010, up to $5,000 ($6,000 for each spouse age 50 or older by the end of 2010) can be contributed to IRAs on behalf of each spouse, even if one spouse has little or no compensation.

For more information on the general limit and the spousal IRA limit, see How Much Can Be Contributed? in Publication 590.

Generally, you can deduct the lesser of the contributions to your traditional IRA for the year or the general limit (or spousal IRA limit, if applicable) just explained. However, if you or your spouse was covered by an employer retirement plan at any time during the year for which contributions were made, you may not be able to deduct all of the contributions. Your deduction may be reduced or eliminated, depending on your filing status and the amount of your income. Your deduction may also be affected by social security benefits you received. For more information, see Limit if Covered by Employer Plan in Publication 590.

The difference between your total permitted contributions and your IRA deduction, if any, is your nondeductible contribution. You must file Form 8606, Nondeductible IRAs, to report nondeductible contributions even if you do not have to file a tax return for the year.
