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.
