Form CT-1040 EXT is a Connecticut Individual Income Tax form. The IRS and most states will grant an automatic 6-month extension of time to file income tax and other types of tax returns, which can be obtained by filing the proper extension request form. Obtaining an extension will prevent you from being subject to often very large failure-to-file penalties. However, in most cases this extension does not exempt you from the requirement to pay any tax owed in full by the return's original filing date.

About the Individual Income Tax

The IRS and most states collect a personal income tax, which is paid throughout the year via tax withholding or estimated income tax payments.

Most taxpayers are required to file a yearly income tax return in April to both the Internal Revenue Service and their state's revenue department, which will result in either a tax refund of excess withheld income or a tax payment if the withholding does not cover the taxpayer's entire liability. Every taxpayer's situation is different - please consult a CPA or licensed tax preparer to ensure that you are filing the correct tax forms!
