Along with your W-2 state filing, Connecticut mandates the filing of the Annual Reconciliation Form CT-W3 to be submitted. You will be able to submit both forms to the state through ExpressTaxFilings.
|Filing Type||Due Date|
|Electronic Filing||January 31|
You must file the form W-2 & W-2c even if there was no state withholding.
Nothing, if you are filing electronically with ExpressTaxFilings!
The state of Connecticut accepts both e-filing and paper filing.
