The Colorado net operating loss of a corporation is computed in the same manner as the federal net operating loss deduction except that in the case of a corporation apportioning income, it is that part of the federal net operating loss, as modified, that is from Colorado sources. Federal limitations on carryover losses between predecessor and successor corporations apply for Colorado income tax purposes.
11. How do you file a return for an LLC?
A Limited Liability Company (LLC) is a business organizational structure that is allowed in Colorado. The Department will generally treat the income from your LLC in the same way as indicated on your federal income tax return. Review the LLC classification criteria on the Internal Revenue Service (IRS) website for more information. For example, if you filed as a partnership at the federal level, then you generally would file as a partnership in Colorado, as well.
12. What if I don't pay my business' tax liability?
When you do not pay your tax in full when you file your return, if you paid late and owe penalty and interest or if you did not file a return and the Department filed one for you. When a Notice of Deficiency is issued, you have 30 days to notify the department if you disagree with the bill. Be sure to read the notice carefully to understand your rights and to see what documentation is required.
Review FYI General 11 for more information on penalties and interest.
If you do not pay, dispute or protest the bill within the allotted time, the Department will issue a Final Determination and Demand for Payment. Should you fail to pay the balance in full or start a monthly installment plan, CDOR may take certain actions to collect your unpaid taxes.
