Furnishing amended withholding or exemption certificate

(b) (1) In completing a Form CT-W4, an employee is required to check a filing status.

(A) Filing status "A" is to be claimed if an employee is married but filing a federal income tax return separately from his or her spouse; or is married and filing a federal income tax return jointly with his or her spouse who is employed and their combined Connecticut adjusted gross income is $100,500 or less.

(B) Filing status "B" is to be claimed if an employee is eligible to file, and filing, a federal income tax return as a head of household.

(C) Filing status "C" is to be claimed if an employee is married and filing a federal income tax return jointly with his or her spouse who is not employed.

(D) Filing status "D" is to be claimed if an employee is married and filing a federal income tax return jointly with his or her spouse who is employed, and their combined Connecticut adjusted gross income is more than $100,500; or if the employee has significant nonwage income and wishes to avoid having insufficient tax withheld; or if the employee is a nonresident individual and has substantial other income.

(E) Filing status "E" is to be claimed if an employee expects a refund of all Connecticut income withheld during the taxable year because he or she expects to have no Connecticut income tax liability for such year.

(F) Filing status "F" is to be claimed if an employee is unmarried but is not eligible to file a federal income tax return as a head of household.

(2) Some examples of when a new Form CT-W4 is required to be provided are as follows:

Example 1: X originally indicated filing status "A" on her Form CT-W4 because she is married, filing jointly, and the combined income of the spouses was expected to be less than or equal to $100,500. In August, X's spouse changed jobs, and as a result the spouses' combined income for the taxable year is expected to exceed $100,500. Filing status "A" would therefore no longer be correct, and X is required to file a new Form CT-W4 within 10 days of the change and check filing status "D" on her new Form CT-W4.

Example 2: Y originally indicated filing status "C" on his Form CT-W4 because he is married, filing jointly, and his spouse was not employed. In May, Y's spouse became employed. Filing status "C" would therefore no longer be correct, and Y is required to file a new Form CT-W4 within 10 days of the change and check either filing status "A" on his new Form CT-W4 and use the supplemental table for married couples filing jointly that is attached thereto, if the spouses' combined income for the taxable year is not expected to exceed $100,500, or filing status "D" on his new Form CT-W4, if the spouses' combined income for the taxable year is expected to exceed $100,500.

Example 3: Z requested reduced withholding on her original Form CT-W4 because she expected to have a loss passed through to her from a partnership in which she is a partner. In February, however, she learns that the expected loss will be much less than originally anticipated. Z is required to redetermine whether she is entitled to reduced withholding, and, if the adjustment of the loss amount results in a change in the amount to be withheld, file a new Form CT-W4 within 10 days of the change.
