Other Helpful Information



Rounding Off to Whole Dollars

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.


New Owners

Do not use the previous owner’s form to file your return. Any change in ownership requires a new Connecticut Tax Registration Number.


Power of Attorney

To authorize one or more individuals to represent you or your business before the Department of Revenue Services (DRS), use LGL-001, Power of Attorney. This authorization allows your representative(s) to receive and inspect confidential tax information and to act on your behalf in matters before DRS.

Submit LGL-001 electronically by sending it to DRS through a secure web message in myconneCT. Log in to myconneCT, open the More … menu, locate the Correspondence group and click the Send a Message hyperlink.


Waiver of Penalty

To make a penalty waiver request, complete and submit Form DRS-PW, Request for Waiver of Civil Penalty, to the DRS Operations Bureau/Penalty Waiver through myconneCT, by mail, or fax.
