The Section 179 carryover comes in handy if you reach your maximum deduction amount for the year. If this happens, you might be able to carry over the amount to the following year. Here is an example of the Section 179 carryover: If a small business takes $100,000 of Section 179 deduction and has $60,000 of taxable income before the deduction, $40,000 ($100,000 minus $60,000) can be carried forward next year. Ask your accountant about the Section 179 carryover, as each business owner's situation is unique.
