Ok ... short lesson in depreciation/179 deduction ... this is the only legal way to manipulate the bottom line of a return after the tax year has closes. There are many options and you should explore them all to see how they will benefit you this tax year and future tax years. Sometimes taking all the expenses you can now will only hurt you in the future.
Say you have an asset with a value of $1000 but your Sch C is already at a loss ... options are:
1) take regular depreciation over the class life of the asset (allowed)
2) take the entire cost as bonus depreciation (allowed)
3) take the 179 deduction on the entire cost ... (it will not be allowed instead it will be carried forward)
4) take some of the cost as a 179 deduction (not allowed) and the rest as reg depreciation (allowed)
