Reporting corporate expenses beyond income beneficial?

Out of curiosity, is it necessary to continue reporting expenses beyond the annual income, for tax reasons? Or is it okay to stop once the expense amount is equal to or more than income amount?

For example, if my income was 20000 for the tax year, and I purchased a company car for 21000. Do I still need to report gas expenses, meals, travel, etc? is there any benefit to doing so? is it required? If I keep adding expenses, assume I will end up with 28000 expenses and 20000 income – either way I am at a net loss..
