Example—Nonrefundable portion of credit for qualified sick and family leave compensation increased. You originally reported a $1,000 nonrefundable portion of credit for qualified sick and family leave compensation on your 2021 Form CT-1, line 16, but later determined that you understated qualified sick leave compensation eligible for the credit. If your period of limitations is still open, use Worksheet 1 to refigure the correct nonrefundable portion of the credit for qualified sick and family leave compensation and you determine that the correct credit is now $2,000. To correct the error, figure the difference on Form CT-1 X as shown.

Column 1 (corrected amount) 2,000.00 Column 2 (Form CT-1, line 16) - 1,000.00

Column 3 (difference) 1,000.00

To properly show the credit increase as a reduction to your balance, enter the positive number in column 3 as a negative number in column 4. Here is how you would enter the numbers on Form CT-1 X, line 19.

Be sure to explain the reasons for this correction on line 43.
