Purpose:This Announcement alerts married individuals who are both employed and file a joint Connecticut income tax return that it may be necessary to increase or decrease the amount of Connecticut income tax withheld from one spouse’s wage income to avoid underwithholding or overwithholding that may result when both incomes are combined.
Any reference in this Announcement to a spouse or married individual also refers to a party to a civil union recognized under Connecticut law. For more information on civil unions recognized under Connecticut law, visit the Attorney General’s Web site at www.ct.gov/ag for Attorney General Opinion 2005-024.
When to Use the Supplemental Table to Adjust Your Withholding: If you and your spouse are both employed, intend to file a joint Connecticut income tax return, and select Withholding Code "A" on Form CT-W4, Employee’s Withholding Certificate, the amount of Connecticut income tax withheld from one spouse’s wages may need to be adjusted. Although the Connecticut withholding tables provide the accurate amount of Connecticut withholding for each spouse’s own wage income when a joint Connecticut income tax return is filed, the application of the personal exemption and credit is based upon the combined income of both spouses. Therefore, the amount of combined withholding as determined by the tables may not be enough to cover the total Connecticut income tax liability. If you do not have enough Connecticut income tax withheld throughout the year, you may be required to make estimated Connecticut income tax payments and may be subject to interest if insufficient estimated tax payments are made.
To minimize this problem, use the Supplemental Table for Married Couples Filing Jointly to help you adjust your withholding. The table is included on Pages 3 and 4 of Form CT-W4, which is available from your employer. If you need to adjust your withholding, complete a new Form CT-W4 and give it to your employer as soon as possible.
Other Method to Help You Adjust Your Connecticut Withholding: The supplemental table is a quick and easy tool to help you adjust your Connecticut withholding, but the results may not match your required withholding exactly. For example, if you or your spouse, or both, have non-wage income (such as income from a sole proprietorship, partnership, trust or estate, S corporation, interest, dividends, capital gains, pension, annuity, or gambling winnings), you should take this other income into account when adjusting your withholding. For a precise method of determining your withholding, see Informational Publication 2007(1), Is My Connecticut Withholding Correct?
