business expenses tax deductions?

And is this your own personal tools and tool box that you can carry around and use at home also when you are not working at your regular job shop as an employee with and employer that will issuing you a W-2 form after the end of the tax year showing you your GROSS wages earnings in the Box 1 of the W-2 form during the 2013 tax filing season for this purpose RIGHT.
Not completely when you can and will also be using them for your own personal use when you would choose to do so and when you would no longer be working at firestone auto care you would be taking the tool box and any of your personal tools back home with you for your personal use or to your next mechanic job for this purpose and time in your life RIGHT.
When it is REQUIRED by your employer this might be possible BUT you would have to be able to qualify to use the schedule A itemized deductions of your 1040 income tax return to start with for this purpose and then as a part of your employer related business expenses as miscellaneous itemzed deduction amounts that would also be subject to the 2% of adjusted gross income limit before any of the amount would be added to all of your itemized deduction on the 1040 income tax return for this purpose and time in your life.

If you have expenses that qualify as miscellaneous itemized deductions, you can deduct the total amount of those expenses only to the extent that they exceed 2% of your adjusted gross income.
There are three types of expenses that are subject to the 2% limit. They are unreimbursed employee expenses, tax preparation fees and other expenses. For an explanation of deductible and nondeductible expenses refer to Publication 529, Miscellaneous Deductions.

As an "expense", no. An "expense" is something that gets used up in less than a year, like paper towels.

Things that last more than a year are capital expenditures. You calculate the "depreciation". Each year that you own the thing, you write off that year's "depreciation"....Show more
