3% of the amount by which your AGI exceeds $311,300 if married filing jointly or qualifying widow(er), $285,350 if head of household, $259,400 if single, or $155,650 if married filing separately.
Before you figure the overall limit on itemized deductions, you first must complete Schedule A (Form 1040), lines 1 through 28, 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 24), the limit on certain meal and entertainment expenses (chapter 26), and the 2%-of-adjusted-gross-income limit on certain miscellaneous deductions (chapter 28).
For tax year 2016 Bill and Terry Willow are filing a joint return on Form 1040. Their adjusted gross income on line 38 is $325,500. Their Schedule A itemized deductions are as follows:

|Investment interest expense—line 14||41,000|
|Gifts to charity—line 19||21,000|

The Willows’ investment interest expense deduction ($41,000 from Schedule A (Form 1040), line 14) isn't 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. Of their $142,140 total itemized deductions, the Willows can deduct only $141,714 ($142,140 - $426). They enter $141,714 on Schedule A (Form 1040), line 29.
