Connecticut · Payroll closure
Close a Connecticut payroll tax account.
Connecticut does not give you a window. If you go out of business or permanently stop paying wages, the state expects notice immediately, and the notice takes the form of filing Form CT-941 for the current quarter. Then the annual reconciliation and every W-2 still have to follow.

State fee. $0. Connecticut does not charge to close a withholding account or cancel a Department of Labor registration. Tax already owed is unaffected.
Our fee. $180 per state, flat. State fees are passed through at cost.
When you have to close or cancel
Going out of business or permanently ceasing to pay wages. Connecticut's instruction is to notify Revenue Services immediately by electronically filing Form CT-941 for the current quarter, so the notification and a return are the same act.
Final returns come first
Three things, not one. File CT-941 for the current quarter, file Form CT-W3, the Connecticut Annual Reconciliation of Withholding, and issue Forms W-2 to all employees while submitting copies to Revenue Services. All returns must be filed up to the closing date, so a gap anywhere in the year has to be filled before the account closes cleanly.
How long it takes
Connecticut does not publish a processing time. What it publishes instead is the word immediately, which is unusual. The obligation is on the speed of your notice rather than on the state's speed in acting on it.
What we do
We confirm which accounts are open, file any outstanding final returns, submit each cancellation, and follow up until every agency confirms in writing. You keep the client. We never email them.
Opening an account in another state instead? State payroll tax registration covers the withholding and unemployment accounts payroll software will not open.
What makes Connecticut harder than average
- Immediately is the actual instruction. Most states give 10, 15, or 30 days. Connecticut says notify Revenue Services immediately when you go out of business or permanently stop paying wages, which leaves no comfortable reading.
- The notification is a return. You notify by electronically filing CT-941 for the current quarter, so if you were expecting a form called something like Notice of Closure, there is not one. The quarterly reconciliation does that job.
- The annual reconciliation still comes due. CT-W3 and the W-2s are separate from CT-941 and separate from closing the account in myconneCT. Businesses that file the quarterly and close the account in the portal frequently stop there.
- Returns are owed up to the closing date, with no gaps. If a quarter earlier in the year was missed, it has to be filed before the closure is clean, and Connecticut states the requirement plainly rather than discovering it later.
Dissolving the company is not the same as closing the tax accounts
Articles of dissolution leave the withholding, unemployment, and sales tax accounts open, and those agencies keep expecting returns until each one is closed with them. That is the separate filing that stops the notices.
How Connecticut compares
Every state closes them differently. The table compares Connecticut with the other states we have documented, agency by agency.
For CPAs and bookkeepers
Send the state, the last payroll or sale date, and the account numbers. The written confirmations come back to you. We do not dissolve the company and we do not take over payroll.
Questions and answers
How quickly do I have to tell Connecticut?
Immediately, in the state's own words, by electronically filing Form CT-941 for the current quarter. There is no stated grace period to work with.
Is filing CT-941 enough?
No. You also file Form CT-W3, the Connecticut Annual Reconciliation of Withholding, issue Forms W-2 to all employees, and submit copies of those W-2s to Revenue Services. Then close the account in myconneCT.
Where in myconneCT do I close the account?
Open the More menu, find Taxpayer Updates, and click Close Accounts, then follow the prompts. It is not on the main dashboard, which is why people miss it.
Does this cancel my Department of Labor registration?
No. If the business had employees, the registration with the Connecticut Department of Labor has to be cancelled separately.
What do you need from me to start?
The legal name and Connecticut Tax Registration Number, the Department of Labor registration number, the closing date, and which quarters and annual reconciliations are already filed.
