General Information
This Online Guide to Connecticut Business Tax Credits provides a brief overview of
Tax credits are tax expenditures paid for by foregoing revenues that would otherwise be paid to the state. Tax credits are also a matter of legislative grace and, therefore, narrowly construed. Careful attention must be paid to determine:
- Who is eligible to claim the tax credit;
- Whether the tax credit has an application process that must be followed;
- Whether the tax credit has a flow-through provision;
- Whether the tax credit is assignable and transferable;
- The timing and manner in which the tax credit must be claimed;
- Specific state taxes to which the tax credit applies;
- Ordering rules for claiming tax credits;
- Applicable limitations on the amount of tax credits that may be applied to a particular tax;
- Whether the tax credit may be carried forward if not used in the income year when earned; and
- Whether the tax credit may be refunded.
Application Process
Tax credits may require an application process or pre-certification of eligibility. If a tax credit requires an application, it is noted in the summary of the tax credit.
Who is Eligible to Earn the Tax Credit
The authorizing state statutes usually specify what entities may earn tax credits. Under the majority of tax credit statutes, only the entity that earned the credit may claim the credit. However, there are tax credits that may be claimed by an entity other than the entity that earned the credit. See the Flow-Through of Tax Credits and Assignment and Transfer of Tax Credits sections below. Please review the language of the specific tax credit to determine what entities may claim the credit.
Flow-Through of Tax Credits
Tax credits under Conn. Gen. Stat. Chapter 208 (Corporation Business Tax) follow much of the Internal Revenue Code and federal income tax principles, including the conduit treatment of partnerships. See Bell Atlantic Nynex Mobile v. Commissioner of Revenue Services, 273 Conn. 240 (2005). However, other chapters of the Connecticut General Statutes do not and conduit treatment is not applicable to such chapters.
Assignment and Transfer of Tax Credits
Tax credits that may be assigned are specifically identified in the reference chart and in the tax credit summaries. Unless otherwise specifically provided statutorily, tax credits may only be assigned once. If a tax credit is assigned, the assignee must claim the tax credit when the business that earned the tax credit would have been eligible to claim the tax credit. If a tax credit that allows carryforward is assigned, the assignee is entitled to the same carryforward provisions.
The Department of Revenue Services will rely solely on documentation provided by the Department of Economic and Community Development or the Department of Energy and Environmental Protection with respect to proof of assignment.
Claiming the Tax Credits
For most tax credits, there is a specific form that must be completed to claim the tax credit. Failure to provide all documentation required for the specific tax credit form may result in a denial of the tax credit. In addition to completing the applicable tax credit forms, you must report any such tax credit on Form CT-1120K, Business Tax Credit Summary.
Important note: Do not use Form CT-1120K in connection with a tax credit to be applied against the taxes imposed by Chapter 207 (Insurance/ Health Care) or Chapter 229 (Income Tax) of the Connecticut General Statutes. Instead, taxpayers subject to the Insurance/Health Care Taxes should use Form 207K, Insurance/Health Care Tax Credit Schedule, and taxpayers subject to the Income Tax should use Schedule CT-IT Credit, Income Tax Credit Summary. Please refer to the appropriate tax return instructions for information on how to claim credits against these taxes.
To Which Taxes Do Tax Credits Apply?
Each state statute authorizing a tax credit also specifies the tax or taxes against which the tax credit may be applied. Please refer to the tax credit summaries to determine the taxes against which specific tax credits may be applied.
Ordering Rules for Claiming Corporation Business Tax Credits
The Connecticut General Statutes specify the order in which tax credits are to be applied to the Corporation Business Tax. In accordance with these rules, tax credits must be applied (used) in the following order:
1. Carrybacks expiring first;
2. Current year tax credits that do not have a carryforward or carryback provision;
3. Any tax credit carryforward expiring first;
4. Non-expiring tax credits.
Taxpayers may apply the Electronic Data Processing Equipment Property tax credit only after all other allowable tax credits have been applied. If a taxpayer claims the Electronic Data Processing Equipment Property tax credit, the taxpayer must first use the tax credit against the tax imposed under Chapter 208, and then against the taxes imposed under Chapters 207, 208a, 209, 210, 211, or 212.
Please refer to the appropriate tax return instructions for information on the ordering rules for claiming business tax credits against taxes other than the Corporation Business Tax.
Limitation on the Application of Tax Credits
Tax Credits Against the Corporation Business Tax (Chapter 208)
The amount of tax credits otherwise allowable against the taxes imposed under Chapter 208 for any income year may not exceed 70% of the amount of tax due prior to the application of tax credits or be used against the minimum tax of $250.
Tax Credits Against Insurance/Health Care Centers Taxes (Chapter 207)
The amount of tax credits otherwise allowable against the taxes imposed under Chapter 207 may not exceed 70% of the amount of tax due prior to the application of tax credits. The same rule applies for all tax credits. For the 2013 and 2014 calendar years, the amount of tax credits allowed against the taxes imposed under Chapter 207 is reduced. For those three calendar years, the amount of tax credits allowed against the taxes imposed under Chapter 207 may not exceed 70% for Insurance Reinvestment Fund and Second Insurance Reinvestment Fund tax credits, 55% for Digital Animation, Film Production and Film Production Infrastructure tax credits, and 30% for all other credits.
Carryforward or Carryback of Tax Credits
Many of the tax credits may be carried forward for a period of years if they are not used in the year they are claimed. If a tax credit may be carried forward, the statute specifically provides for carryforward and also specifies the term of years for which the tax credit may be carried forward.
The Neighborhood Assistance tax credit and the Housing Program Contribution tax credit are the only tax credits that may be carried back.
Refund of Tax Credits
Under certain circumstances, the Research and Development (Nonincremental) Expenses tax credit and the Research and Experimental (Incremental) Expenditures tax credit may be exchanged with the state for 65% of their value. See the summaries for the Research and Development (Nonincremental) Expenses tax credit and the Research and Experimental (Incremental) Expenditures tax credit.
No other business tax credit is refundable.
