Corporation name Connecticut Tax Registration Number DECD Eligibility Certificate Number (If applicable) Complete this form in blue or black ink only. Do not use staples. Please note that each form is year specific. The correct year’s form must be used. Use Form CT‑1120 RDC to claim the tax credit available under Conn. Gen. Stat. § 12‑217n for research and development expenses paid or incurred during the income year for research and development conducted in Connecticut. Required Attachments Attach a detailed schedule that identifies the research and development expenses as to the type, amount, and location in Connecticut where conducted. Definitions Connecticut research and development expenses are those amounts deductible under § 174 of the Internal Revenue Code (IRC) of 1986, as in effect on May 28, 1993, (determined without regard to §  280C(c) thereof), and basic research payments as defined under IRC § 41, to the extent not deducted under IRC § 174. The expenses must be paid or incurred by the taxpayer for research and development and basic research conducted in Connecticut and may not be funded, within the meaning of IRC § 41(d)(4)(H), by any grant, contract, or otherwise by a person or governmental entity other than the taxpayer unless the other person is included in a combined return with the person paying or incurring the expenses. Overhead and other expenses, including general and administrative expenses that relate to a corporation’s activities as a whole and not specifically to the research and development effort will not qualify. Qualifying expenses include but are not limited to: • Expenses incurred in connection with the taxpayer’s trade or business that represent research and development costs in the experimental or laboratory sense; • All costs incident to the development of an experimental or pilot model, a plant process, a product, a formula, an invention, or similar property, and the improvement of already existing property of the type mentioned; and • Costs of obtaining a patent, such as attorneys’ fees expended in making and perfecting a patent application. Qualified Small Business is defined as a company that has gross income for the previous income year that does not exceed $100 million and has not met the gross income test through transactions with a related person, as defined in Conn. Gen. Stat. § 12‑217w. Tentative Tax Credit Computation For a qualified small business, the tentative tax credit allowed for research and development expenses is equal to 6% of such expenses. Any company other than a qualified small business must use the tentative rate schedule below to determine the amount of the tentative credit. The amount of credit available to companies that have revenues in excess of $3 billion, employing more than 2,500 employees, and headquartered in an Enterprise Zone shall be the tentative credit allowed or 3.5% of the total research and development expenses, whichever is greater. A company that pays or incurs research and development expenses in excess of $200 million for the income year must obtain an eligibility certificate from the Department of Economic and Community Development (DECD) prior to claiming the credit.

Form CT-1120 RDC is a Connecticut Corporate Income Tax form. States often have dozens of even hundreds of various tax credits, which, unlike deductions, provide a dollar-for-dollar reduction of tax liability. Some common tax credits apply to many taxpayers, while others only apply to extremely specific situations. In most cases, you will have to provide evidence to show that you are eligible for the tax credit, and calculate the amount of the credit to which you are entitled.

About the Corporate Income Tax

The IRS and most states require corporations to file an income tax return, with the exact filing requirements depending on the type of company.

Sole proprietorships or disregarded entities like LLCs are filed on Schedule C (or the state equivalent) of the owner's personal income tax return, flow-through entities like S Corporations or Partnerships are generally required to file an informational return equivilent to the IRS Form 1120S or Form 1065, and full corporations must file the equivalent of federal Form 1120 (and, unlike flow-through corporations, are often subject to a corporate tax liability).

Additional forms are available for a wide variety of specific entities and transactions including fiduciaries, nonprofits, and companies involved in other specific types of business.
