Information About the Supplemental Withholding Table for Married Individuals Filing Jointly Who Both Earn Wage Income

This publication has been modified and superseded by AN 2004(1)


PURPOSE: The purpose of this Announcement is to alert married individuals who intend to 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 under withholding or over withholding that may result when both incomes are combined.


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 Filing Status "A" on Form CT-W4, Employee’s Withholding or Exemption 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 will 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. This table is included as part of Form CT-W4, which is available from your employer.


HOW TO USE THE SUPPLEMENTAL TABLE:  Follow the instructions on Form CT-W4 to determine if you need to increase or decrease the amount of Connecticut income tax that would otherwise be withheld. If you need to make a change, complete a new Form CT-W4 and give it to your employer as soon as possible.

Form CT-W4 is a four-page publication. The supplemental table may be found on pages 3 and 4.


ANOTHER METHOD TO HELP YOU ADJUST YOUR CONNECTICUT WITHHOLDING:  The supplemental table is a quick and easy tool to help you adjust your 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 2000(12), Is My Connecticut Withholding Correct?
