For equipment that I purchased that was installed at a client's office, how do I write that off? Or do I subtract it from the payments I received from them (1099)?

I did computer consulting on the side. I was hired to install new internet equipment. I paid for the equipment and the company paid me for both the equipment and the labor. Since labor and equipment are combined on one check, I am taxed on that income, but how do I offset the amount I paid for the equipment?

You can deduct the cost of this equipment as a business expense categorized as Supplies.

It is all under income.  Then you enter it as an expense.  Probably under  Supplies or line 27a  Other Misc Expenses.

You may use the supplies category. Alternatively, you can enter it as other expenses. There, you can label it, for example, as "equipment  for Jones job".

 Do not use the inventory category.
