Are You Subject to the Limit?

You are subject to the limit on certain itemized deductions if your adjusted gross income (AGI) is more than $142,700 ($71,350 if you are married filing separately). Your AGI is the amount on Form 1040, line 37.

Which Itemized Deductions Are Limited?

The following Schedule A (Form 1040) deductions are subject to the overall limit on itemized deductions.

  • Taxes—line 9.

  • Interest—lines 10, 11, and 12.

  • Gifts to charity—line 18.

  • Job expenses and most other miscellaneous deductions—line 26.

  • Other miscellaneous deductions—line 27, excluding gambling and casualty or theft losses.

Which Itemized Deductions Are Not Limited?

The following Schedule A (Form 1040) deductions are not subject to the overall limit on itemized deductions. However, they are still subject to other applicable limits.

  • Medical and dental expenses—line 4.

  • Investment interest expense—line 13.

  • Casualty and theft losses from personal use property—line 19.

  • Casualty and theft losses from income-producing property—line 27.

  • Gambling losses—line 27.

How Do You Figure the Limit?

If your itemized deductions are subject to the limit, the total of all your itemized deductions is reduced by the smaller of:

  • 3% of the amount by which your AGI exceeds $142,700 ($71,350 if married filing separately), or

  • 80% of your itemized deductions that are affected by the limit. See Which Itemized Deductions Are Limited, earlier.

Before you figure the overall limit on itemized deductions, you first must complete Schedule A (Form 1040), lines 1 through 27, including any related forms (such as Form 2106, Form 4684, etc.).

The overall limit on itemized deductions is figured after you have applied any other limit on the allowance of any itemized deduction. These other limits include charitable contribution limits (chapter 26), the limit on certain meals and entertainment (chapter 28), and the 2%-of- adjusted-gross-income limit on certain miscellaneous deductions (chapter 30).

Itemized Deductions Worksheet.   After you have completed Schedule A (Form 1040) through line 27, you can use the Itemized Deductions Worksheet in the Form 1040 instructions for Schedule A to figure your limit. Enter the result on Schedule A (Form 1040), line 28. Keep the worksheet for your records.

Tip
You should compare the amount of your standard deduction to the amount of your itemized deductions after applying the limit. Use the greater amount when completing Form 1040, line 39. See chapter 22 for information on how to figure your standard deduction.

Example

For tax year 2004, Bill and Terry Willow are filing a joint return on Form 1040. Their adjusted gross income on line 37 is $259,600. Their Schedule A itemized deductions are as follows:

Taxes—line 9   $17,900
Interest—lines 10, 11, and 12   45,000
Investment interest expense
—line 13
  41,000
Gifts to charity—line 18   21,000
Job expenses—line 26   17,240
Total   $142,140
     

The Willows' investment interest expense deduction ($41,000 from Schedule A (Form 1040), line 13) is not subject to the overall limit on itemized deductions.

The Willows use the Itemized Deductions Worksheet in the Schedule A (Form 1040) instructions to figure their overall limit. Their completed worksheet is shown as Table 31-1.

Of their $142,140 total itemized deductions, the Willows can deduct only $138,633 ($142,140 - $3,507). They enter $138,633 on Schedule A (Form 1040), line 28.
