Upcoming CT DRS webinar: Select to register for the upcoming Withholding Tax Overview Webinar on Wednesday, July 24, 2024, at 10:00 a.m.

Welcome to FSET (Federal/State Employment Taxes)

Connecticut’s partnership with the Internal Revenue Service (IRS), Connecticut Department of Labor (DOL), Connecticut Department of Revenue Services (DRS), and the software community resulted in the Federal/State Employment Taxes (FSET) program which supports payment and filing of employment taxes over the Internet.

The mission of the FSET program is to reduce employer burden by simplifying the process for the quarterly filing of state and federal tax and wage reports and making employment tax payments. The program seeks to facilitate the development of commercial software applications for the single point electronic transmission of employer quarterly tax and wage reports that satisfy both state and federal obligations.


The program is open to software developers, transmitters, and payroll service providers who will act as "reporting agents."


Use FSET to file the following returns safely and securely:

  • Federal Payroll taxes (Forms 940 and 941)

  • CT Payroll Withholding taxes (Forms CT-941),

  • CT Unemployment taxes (Forms UC-2 and UC-5a)

  • Payments associated with Withholding and Unemployment taxes 

If you have a question, comment, or suggestion regarding the FSET Program, e-mail us at: DRS.FSET@po.state.ct.us.

What returns can I file using FSET?

FSET allows taxpayers to file to following returns:

  • Form CT-941, DRS Connecticut Quarterly Reconciliation of Withholding
  • Form UC-2, DOL Employer Contribution Return
  • Form UC-5a, DOL Employee Quarterly Earning Report

How do I make payments using FSET?

All balances due must be paid electronically using direct payment.  Direct payment allows you to file returns at your convenience and have payments "warehoused" until a later date.  Payment can be transferred from your bank account to DRS or DOL any day up to the legal due date of the return.

If you are currently a registered user of the Connecticut Electronic Funds Transfer (EFT) program, you may make FSET payments using EFT.

Who is eligible to use FSET?

The FSET schemas and standards are designed to be used by software developers, transmitters, and payroll service providers to enable any business to file its payroll tax returns and payments.

Transmission using FSET may be either by an individual employer or a third party, using the required XML record format.

If your company is interested in using FSET for the quarterly filing of state and federal tax and wage reports and making employment tax payments ask your payroll company to contact the DRS to get involved or contact an Approved FSET Vendor.

What is required to use FSET?

Both the DOL and DRS must approve the transmitter responsible for submitting FSET data to the State of Connecticut as well as the software that generates the files.  The FSET XML schemas and the State User Guide as well as news and alerts for IRS e-file for Business – Software Developers and Transmitters are housed on the IRS Web site.
