You must round off cents to the nearest whole dollar on your returns and schedules. If you do not round, DRS will disregard the cents. Round down to the next lowest dollar all amounts that include 1 through 49 cents. Round up to the next highest dollar all amounts that include 50 through 99 cents. However, if you need to add two or more amounts to compute the amount to enter on a line, include cents and round off only the total.
Example: Add two amounts ($1.29 + $3.21) to compute the total ($4.50) to enter on a line. $4.50 is rounded to $5.00 and entered on a line.
Do not use the previous owner’s form to file your return. Any change in ownership requires a new Connecticut Tax Registration Number.
