The Colorado 1Dr 0112Ep form, officially known as the 2014 Colorado Estimated Tax - Corporate Worksheet, is a crucial document for corporations operating within the state. This form is designed to assist businesses in calculating their estimated tax liabilities for the year 2014, ensuring compliance with state tax regulations. The corporate tax rate for Colorado is set at 4.63%, and the form guides users through various calculations, including the recapture of prior year credits and the application of estimated credits from Form 112CR. Corporations are required to pay estimated taxes if they anticipate their net tax liability will exceed $5,000. The form also outlines the necessary payment schedules, which include four quarterly due dates: April 15, June 15, September 15, and December 15. Payments can be made electronically to streamline the process and reduce the risk of errors. Furthermore, the form emphasizes the importance of accuracy in payment amounts, advising users to round payments to the nearest dollar and to ensure that checks match the amounts indicated on the payment voucher. In cases where electronic payment is not feasible, a detachable coupon is provided for mailing payments.
