The amount here is the deduction you're allowed for all your 2007 unreimbursed job-related expenses (and those of your spouse, if you're married filing a joint return). It includes the costs of:

• Travel for work
• 50% of meals and entertainment
• Supplies
• Professional books and publications
• Home office and vehicles expenses
• Depreciation of tools and other property used for your job
• Expenses to look for a job within your current occupation

You're only allowed to deduct these kinds of expenses to the extent they exceed 2% of your adjusted gross income. We've taken care of these limitations for you.
