Under new legislation, the 10% surtax has been extended two additional years to income years beginning on or after January 1, 2021, and prior to January 1, 2023. Beginning with income year 2022, a company may utilize research and experimental tax credits available under section 12‑217j (R&E Tax Credits) and research and development tax credits available under section 12‑217n (R&D Tax Credits) in excess of the standard credit limitation. Capital Base Tax Phaseout Under prior law, the capital base tax phaseout was scheduled to begin in income year 2021. Under new legislation, the capital base tax portion of the corporation business tax will begin to phase out starting in income year 2024 as follows: Income Year Capital Base Tax Rate In general, the amount of tax credits allowable against the corporation business tax shall not exceed 50.01% of the amount of tax due. However, R&E Tax Credits and R&D Tax Credits may be used up to 60% of the tax due in income year 2022, and up to 70% of the tax due in income year 2023 and thereafter. R&D Tax Credit Carryforward Unused R&D Tax Credits that are earned during income years that begin on or after January 1, 2021 may be carried forward for up to 15 years. Beginning prior to January 1, 2024 0.0031 Beginning on or after January 1, 2024, and prior to January 1, 2025 0.0026 Beginning on or after January 1, 2025, and prior to January 1, 2026 0.0021 Beginning on or after January 1, 2026, and prior to January 1, 2027 0.0016 Beginning on or after January 1, 2027, and prior to January 1, 2028 DRS myconneCT 0.0011 Corporation business tax filers can now use myconneCT to file tax returns, make payments, view filing history, and communicate with the agency. For more information, see Where to File on Page 7. The minimum tax remains at $250 for all income years. Relief from Interest on Underpayment of Estimated Taxes Any additional tax attributable to the 10% surtax extension and the delay in the phaseout of the capital base tax, which are both described above, shall not be included when calculating interest on the underpayment of estimated tax (CT-1120I interest). This provision only applies to income years that began on or after January 1, 2021 and before June 23, 2021. For more information, see Special Notice 2021(5), 2021 Legislative Changes Affecting the Corporation Business Tax. Amended Returns Beginning with income year 2021, Form CT-1120X, Amended Connecticut Corporation Business Tax Return, will no longer be issued. Instead, companies that file on a separate company basis can file an amended 2021 corporation business tax return by using Form CT‑1120, Corporation Business Tax Return, and checking the Amended box on Page 4 of the return. Amended returns for prior years can be filed using Form CT-1120X for the applicable year. Combined unitary filers should continue to use Form CT-1120CU, Combined Unitary Corporation Business Tax Return, to file amended returns. For more information, see Amended Returns on Page 9. Page 3 Other Taxes for Which the Corporation May be Liable The information that follows is intended to be a general description of other Connecticut taxes for which a corporation may be liable. Failure to pay these or any taxes for which the corporation is liable may subject the corporation and its officers to civil and criminal penalties. Connecticut Income Tax Withholding Any corporation that maintains an office or transacts business in Connecticut (regardless of the location of the payroll department) and is considered an employer for federal income tax withholding purposes must withhold Connecticut income tax from Connecticut wages as defined in Conn. Agencies Reg. § 12‑706(b)‑1. See the current edition of the Connecticut Employer’s Tax Guide, Circular CT, which is available on the DRS website at portal.ct.gov/DRS. Connecticut Sales and Use Taxes A corporation may be responsible for filing sales and use tax returns. Sales tax is due if the company sells taxable goods or services.

(A copy of federal Form 1120‑H must be available only upon request from DRS.

Form CT‑1120 EXT extends only the time to file the Connecticut Corporation Business Tax return. Form CT‑1120 EXT does not extend the time to pay the amount of tax due. Visit myconneCT at portal.ct.gov/DRS-myconneCT to file Form CT-1120 EXT and to make an extension payment. Interest on any tax not paid by the original due date is computed at 1% per month or fraction of a month until the tax is paid in full. To apply for a waiver from the electronic filing and payment requirement, see Electronic Filing and Payment Waiver on Page 8. When to File Where to File • Every corporation must file a return on or before the fifteenth day of the month following the due date of the corporation’s corresponding federal income tax return for the income year (May 15 for calendar year taxpayers). If the due date falls on a Saturday, Sunday, or legal holiday, the return is considered timely if filed on the next business day. Extension Request Use Form CT‑1120 EXT, Application for Extension of Time to File Connecticut Corporation Business Tax Return, to request a six‑month extension (seven-month extension for corporations with a June 30 fiscal year end) to file Form CT‑1120, Corporation Business Tax Return. It is not necessary to include a reason for the Connecticut extension request if an extension on federal Form 7004, Application for Automatic Extension of Time to File Certain Business Income Tax, Information, and Other Returns, was filed with the Internal Revenue Service. If federal Form 7004 was not filed, the corporation may apply for an extension to file the Connecticut Corporation Business Tax return if there is reasonable cause for the request. To get a Connecticut filing extension the corporation MUST: • Complete Form CT‑1120 EXT in its entirety; • File it on or before the fifteenth day of the month following the due date of the corporation’s corresponding federal income tax return for the income year (May 15 for calendar year taxpayers); and • Pay the amount shown on Line 15. File Electronically All Corporation Business Tax returns must be filed electronically. See Informational Publication 2021(5), Filing and Paying Connecticut Taxes Electronically. Form CT-1120 can be filed electronically through myconneCT. DRS myconneCT allows taxpayers to electronically file, pay, and manage state tax responsibilities. If you file electronically you are expected to pay electronically at the time of filing. Visit myconneCT at portal.ct.gov/DRS-myconneCT. Modernized e-File Program (MeF) DRS accepts Corporation Business Tax returns, extensions and estimated payments through the MeF Program. Check with your software provider for availability. File a Paper Return A paper return may be filed only if a waiver from the electronic filing requirement has been granted. To apply for a waiver from the electronic filing requirement, complete Form DRS‑EWVR, Electronic Filing and Payment Waiver Request. See Electronic Filing and Payment Waiver on Page 8 for more information. If you file a paper return, print in blue or black ink, or type the information requested in the space provided at the top of Form CT‑1120. Mail paper return with payment to: Department of Revenue Services State of Connecticut PO Box 2974 Hartford CT 06104‑2974 Page 7 Mail paper return without payment to: Department of Revenue Services State of Connecticut PO Box 150406 Hartford CT 06115‑0406 • Make check payable to Commissioner of Revenue Services. To ensure payment is applied to the correct account, write “2021 Form CT-1120” and the corporation’s Connecticut Tax Registration Number on the front of the check. Be sure to sign your check and paper clip it to the front of your return. DRS may submit your check to your bank electronically. Do not send cash. The return will meet the timely filed and timely payment rules if the U.S. Postal Service cancellation date, or the date recorded or marked by a designated private delivery service (PDS) using a designated type of service, is on or before the due date. Not all services provided by these designated PDSs qualify. See Policy Statement 2016(4), Designated Private Delivery Services and Designated Types of Service, for a current list of qualified PDSs. If Form CT‑1120 is filed late, see Interest and Penalties on Page 9 to determine if interest and penalty should be reported with this return. Electronic Payment Options All Corporation Business Tax payments (e.g., estimates, extension payments, and return payments) must be made electronically. Non-electronic payments made without an electronic payment waiver will be subject to penalty. See Informational Publication 2021(5), Filing and Paying Connecticut Taxes Electronically. Visit myconneCT at portal.ct.gov/DRS-myconneCT to make an electronic payment. After logging in to myconneCT, find your tax account on the Summary screen, select the Make a Payment link and choose your payment method. • Pay by Direct Payment: Using this option authorizes DRS to electronically withdraw a payment from your bank account (checking or savings) on a date you select up to the due date. Pay by Credit Card or Debit Card: You may elect to pay your tax liability using a credit card (American Express®, Discover®, Master Card®, Visa®) or comparable debit card. A convenience fee will be charged by the credit card service provider. The convenience fee is generally 2.35% of the payment amount, with a minimum charge of $3.95. You will be informed of the amount of the fee and may elect to cancel the transaction. Your payment will be effective on the date that you make the charge. At the end of the transaction, you will receive a confirmation number for your records. As a reminder, even if you pay electronically, you must still file your return by the due date. Tax not paid on or before the due date will be subject to penalty and interest. Electronic Filing and Payment Waiver If a corporation can show that filing and paying electronically creates an undue hardship, the Commissioner of Revenue Services may grant a one year waiver of the electronic filing and payment requirement. Request a waiver by completing Form DRS‑EWVR, Electronic Filing and Payment Waiver Request, no fewer than 30 days before the due date of your first electronic filing and payment. See Policy Statement 2020(2), Requests for Waiver of Electronic Filing and Electronic Payment Requirements. Estimated Tax Payments Every corporation subject to the Connecticut Corporation Business Tax whose estimated current year tax exceeds $1,000 must make its required annual payment in four installments. All Corporation Business Tax estimated tax payments must be filed and paid electronically. To file and pay estimated taxes electronically, visit myconneCT at portal.ct.gov/DRS-myconneCT. See Informational Publication 2021(5), Filing and Paying Connecticut Taxes Electronically. The required annual payment is the lesser of: • 90% of the tax (including surtax) shown on the return for the income year, or, if no return is filed, 90% of the tax for such year; or Estimated Tax Payments Estimated Tax Due Dates Required Payment Amounts The estimated payments for the income year are the lesser of: First ESA - Fifteenth day of the third month of the income year 30% of prior year tax (including surtax) without regard to credits or 27% of current year tax (including surtax) Second ESB - Fifteenth day of the sixth month of the income year * 70% of prior year tax (including surtax) without regard to credits or 63% of current year tax (including surtax) Third ESC - Fifteenth day of the ninth month of the income year * 80% of prior year tax (including surtax) without regard to credits or 72% of current year tax (including surtax) Fourth ESD - Fifteenth day of the twelfth month of the income year * 100% of prior year tax (including surtax) without regard to credits or 90% of current year tax (including surtax) Page 8 * Taking into account all prior estimated tax payments made for this year. • 100% of the tax (including surtax) shown on the return for the previous income year without regard to any credit, if the previous income year was an income year of 12 months and if the company filed a return for the previous income year showing a liability for tax. If the due date falls on a Saturday, Sunday, or legal holiday, the return is considered timely if filed on the next business day. The estimated tax due dates table (on Page  8) indicates the amount due for each installment under the regular installment method. For more information on estimated Corporation Business Tax payments, including information regarding the annualized installment method, see Informational Publication 2021(9), 2021 Q & A on Estimated Corporation Business Tax and Worksheet CT‑1120AE. Amended Returns Any corporation that fails to include items of income or deduction or makes any other error on a return must file an amended return using Form CT‑1120, Corporation Business Tax Return, that applies to the income year being amended. Check the Amended box on Form CT-1120, Page 4, Question 2 and enter the reason for amending. If a corporation has filed an amended federal return with the IRS and the amendment affects the corporation’s Connecticut tax return, then within 90 days of the IRS final determination on that amended federal return, the corporation shall file Form CT‑1120, and attach a copy of federal Form 1120X, Amended U.S. Corporation Income Tax return. Corrections to taxable income made by the IRS must be reported to the Commissioner of Revenue Services on or before 90 days after the final determination of the change. All federal adjustments must be reported on an amended return. An extension request for reporting federal audit changes may be submitted in writing to the Commissioner stating the reason additional time is required. If the adjustment on a Connecticut amended return is not related to an adjustment made on a federal amended return (e.g. an adjustment to Connecticut net income, Connecticut minimum tax base, a Connecticut apportionment factor, a Connecticut net operating loss, or a Connecticut Corporation Business Tax credit), explain such adjustment in detail and attach all appropriate supporting forms and schedules. Interest and Penalties In general, interest and penalty apply to any portion of the tax not paid on or before the original due date of the return. Interest If the corporation does not pay the tax when due, it will owe interest at the rate of 1% per month or fraction of a month until the tax is paid in full. Interest due on the underpayment of estimated tax is computed using Form CT‑1120I, Computation of Interest Due on Underpayment of Estimated Tax. Interest on underpayment or late payment of tax cannot be waived. Penalty for Failure to Remit Payments Electronically The following graduated penalty amounts will apply if you fail to remit payments electronically: • First offense – 10% penalty on the amount of the tax payment, but not more than $2,500; • Second offense – 10% penalty, but not more than $10,000; and • Third and subsequent offenses – 10% penalty. When initiating a payment through your financial institution’s online banking system you must verify that your financial institution is sending an EFT, not a check. Penalty for Late Payment or Late Filing The penalty for late payment or underpayment of Corporation Business Tax is 10% of the tax due or $50, whichever is greater. If a request for a filing extension has been granted, a corporation may avoid a penalty for failure to pay the full amount due by the original due date if it pays: • At least 90% of the tax shown to be due on the return on or before the original due date of the return; and • The balance due with the filing of Form CT-1120, on or before the extended due date. If no tax is due, DRS may impose a $50 penalty for the late filing of any return or report required by law to be filed. Penalty for Willful Failure to File or Pay Anyone who willfully fails to pay the tax or file a return will be fined up to $1,000 or imprisoned up to one year, or both, in addition to any other penalty. Penalty for Willful Filing of a Fraudulent or Materially False Return If you willfully file a tax return you know to be fraudulent or false in any material matter, you may be fined up to $5,000 or imprisoned from one to five years, or both. Page 9 Penalty for Failure to Disclose Listed Transaction A penalty of 75% of the amount of the deficiency may be imposed when it appears that any part of the deficiency is due to failure to disclose a listed transaction, as defined in IRC § 6707A. Waiver of Penalty To make a waiver of penalty request, taxpayers must complete and submit Form DRS‑PW, Request for Waiver of Civil Penalty, to the DRS Operations Bureau/Penalty Waiver through myconneCT at portal.ct.gov/DRS-myconneCT; by mail (to the address below); or fax to 860‑297‑5727 (ATTN: Operations Bureau/Penalty Waiver).

Form CT-1120 Instructions is a Connecticut Corporate Income Tax form. Like the Federal Form 1040, states each provide a core tax return form on which most high-level income and tax calculations are performed. While some taxpayers with simple returns can complete their entire tax return on this single form, in most cases various other additional schedules and forms must be completed, depending on the taxpayer's individual situation, to create a complete income tax return package.

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.
