Connecticut usually releases forms for the current tax year between January and April. We last updated Connecticut Form CT-1120 ES from the Department of Revenue Services in March 2024.
Form CT-1120 ES is a Connecticut Corporate Income Tax form. While most taxpayers have income taxes automatically withheld every pay period by their employer, taxpayers who earn money that is not subject to withholding (such as self employed income, investment returns, etc) are often required to make estimated tax payments on a quarterly basis. Failure to make correct estimated payments can result in interest or penalties.
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.
